RESUMO
PURPOSE: To demonstrate how the use of adjunctive Computed Tomography (CT) can modify diagnosis, treatment options, and operative planning of ankle fractures in comparison with conventional radiographs (CR) in isolation. MATERIALS AND METHODS: A total of 53 patients diagnosed with an ankle fracture between 2011 and 2016, were assessed with CT and CR. Evaluations of the fractures using CR in isolation and CR combined with CT were compared using different readers. Fractures were assessed in terms of type, displacement, size, associated injuries, treatment, patient position and surgical planning. RESULTS: The medial malleolus fractures characteristics (posteromedial fragment and anterior colliculus), the presence of posterior malleolus fracture and its characteristics (displacement, size, posteromedial or posterolateral segment) (ps < 0.042), syndesmosis injury (p < 0.001), and the absence of deltoid ligament lesion (p < 0.001), were more evident with the combination of CT and radiographs. There was an increase in operative indication (p = 0.007), prone positioning (p = 0.002), posterior malleolus surgical treatment (p < 0.001), posterolateral approach for the lateral malleolus (p = 0.003), and syndesmosis fixation (p = 0.020) with the association of CT and CR, among all groups of expertise, with a high interobserver reliability (> 0.75). CONCLUSIONS: The CR may fail to demonstrate subtle lesions, such as posterior malleolus fractures and syndesmotic injuries. The CT evaluation increases the diagnostic precision and improves the quality of information the surgeon receives, what might positively affect patient care. LEVEL OF EVIDENCE III: Retrospective Comparative Study.

INTRODUCTION: After an ankle sprain, up to 20% of patients may develop chronic lateral ankle instability (CLAI) requiring surgical treatment. The objective of this study was to investigate the functional outcomes and rates of return to sport activities in a cohort of non-athlete patients with chronic lateral ankle instability (CLAI) who underwent the opened Brostrom-Gould technique (BGT). MATERIALS AND METHODS: Seventy-nine patients (seventy-nine feet) from three different centers undergoing BGT were reviewed. For clinical and functional analysis, the AOFAS ankle-hindfoot scale was applied and rates of return to sport activities were assessed. Correlation of Δ-AOFAS and rates of return to sport activities with all variables analyzed was performed. RESULTS: Mean AOFAS score improved from 64.6 to 97.2 (p < 0.001). Sixty-one (77.2%) returned to preinjury activities and 18 (22.8%) changed to a lower-level modality. Symptoms of instability were related to Δ-AOFAS (p = 0.020). Change in the sport activity was related to pain and symptoms of instability (p = 0.41 and p < 0.001). CONCLUSION: Recreational athlete patients who underwent the BGT demonstrated excellent functional outcomes after a mean follow-up of 7 years. Residual pain and symptoms of instability after surgery were the main complaints associated with limitations in physical activities.

The incidence of cranial cruciate ligament rupture (CCLR) in dogs is high, which is considered the main arthropathy in the species. Once diagnosed, surgical stabilization is recommended and different treatments are categorized as intracapsular, extracapsular, and osteotomies. There is still no consensus regarding the most optimal method of stabilization, and some studies have attempted to create or improve existing techniques, making them more effective. This study presented an intra-articular stifle stabilization technique using a synthetic polyester implant using 32 anatomical specimens from canine cadavers, which were separated by weight into two groups. The drawer movement was analyzed at three timepoints: intact cranial cruciate ligament (CCL), dissected ligament, and after surgical stabilization using the proposed technique. Results showed a mean cranial displacement of the tibia relative to the femur of 0.61 ± 0.08 millimeters before dissection (mm), 2.61 ± 0.08 mm after dissection, and 0.68 ± 0.08 mm after surgical stabilization (P < 0.01). In conclusion, the intra-articular stabilization technique with polyester thread was effective in stabilizing ex vivo dog stifles after CCL dissection at the immediate postoperative period.
A incidência de ruptura do ligamento cruzado cranial (RLCCr) em cães é alta, sendo considerada a principal artropatia na espécie. Uma vez diagnosticada, a estabilização cirúrgica é recomendada e diversos autores indicam diferentes tratamentos, sendo divididos em intracapsulares, extracapsulares e osteotomias. Ainda não há consenso sobre a melhor forma de estabilização e estudos tem sido desenvolvidos buscando criar ou aprimorar técnicas existentes, tornando-as mais eficazes. O objetivo deste trabalho é apresentar técnica de estabilização intra-articular de joelho, utilizando implante sintético de poliéster. Para isso, 32 peças anatômicas oriundas de cadáveres caninos foram separadas em dois grupos, conforme o peso do animal. Analisamos o movimento de gaveta, em três momentos: ligamento cruzado cranial (LCCr) íntegro, ligamento desmotomizado e pós estabilização cirúrgica pela técnica proposta. Os resultados demonstram deslocamento cranial médio da tíbia em relação ao fêmur antes da desmotomia de 0,61 ± 0,08 milímetros (mm), 2,61 ± 0,08 mm após a desmotomia e 0,68 ± 0,08 mm após estabilização cirúrgica (P < 0.01). Concluímos que, no momento pós-cirúrgico imediato, a técnica de estabilização intra-articular com fio de poliéster é eficaz em estabilizar a articulação de modelo ex vivo de cães após desmotomia do LCCr.

Ankle injuries caused by the Anterior Talofibular Ligament (ATFL) are the most common type of injury. Thus, finding new ways to analyze these injuries through novel technologies is critical for assisting medical diagnosis and, as a result, reducing the subjectivity of this process. As a result, the purpose of this study is to compare the ability of specialists to diagnose lateral tibial tuberosity advancement (LTTA) injury using computer vision analysis on magnetic resonance imaging (MRI). The experiments were carried out on a database obtained from the Vue PACS-Carestream software, which contained 132 images of ATFL and normal (healthy) ankles. Because there were only a few images, image augmentation techniques was used to increase the number of images in the database. Following that, various feature extraction algorithms (GLCM, LBP, and HU invariant moments) and classifiers such as Multi-Layer Perceptron (MLP), Support Vector Machine (SVM), k-Nearest Neighbors (kNN), and Random Forest (RF) were used. Based on the results from this analysis, for cases that lack clear morphologies, the method delivers a hit rate of 85.03% with an increase of 22% over the human expert-based analysis.

Knee injury negatively impacts routine activities and quality of life of millions of people every year. Disruption of tendons, ligaments, and articular cartilage are major causes of knee lesions, leading to social and economic losses. Besides the attempts for an optimal recovery of knee function after surgery, the joint healing process is not always adequate given the nature of intra-articular environment. Based on that, different therapeutic methods attempt to improve healing capacity. Hyperbaric oxygen therapy (HBOT) is an innovative biophysical approach that can be used as an adjuvant treatment post-knee surgery, to potentially prevent chronic disorders that commonly follows knee injuries. Given the well-recognized role of HBOT in improving wound healing, further research is necessary to clarify the benefits of HBOT in damaged musculoskeletal tissues, especially knee disorders. Here, we review important mechanisms of action for HBOT-induced healing including the induction of angiogenesis, modulation of inflammation and extracellular matrix components, and activation of parenchyma cells-key events to restore knee function after injury. This review discusses the basic science of the healing process in knee injuries, the role of oxygen during cicatrization, and shed light on the promising actions of HBOT in treating knee disorders, such as tendon, ligament, and cartilage injuries.

OBJECTIVE: To evaluate anterolateral ligament abnormalities (ALL) at MRI scans and correlate with data from clinical instability tests (Lachman and pivot shift) performed under anesthesia in patients with acute anterior cruciate ligament (ACL) tears. Furthermore, perform multivariate analysis with other variables to isolate the ALL contribution to instability from other abnormalities. METHODS: Retrospective analysis of MRI and instability tests of 95 patients with ACL tears. The ALL was classified as no abnormality, abnormality without discontinuity, and discontinuity. Injuries in other knee ligament structures and menisci were also assessed. Results of instability tests (pivot shift and Lachman) with the patient anesthetized for arthroscopic ACL reconstruction were obtained from the patient database. Statistical analysis was performed using the IBM SPSS 22. RESULTS: ALL abnormalities and iliotibial band (ITB), lateral (LCL), and medial (MCL) collateral ligament injuries showed a statistically significant correlation with the pivot shift test. The ALL MRI abnormalities were associated with the high-grade pivot shift results (p < 0.0005), with an odds ratio of 55.9 for high degrees of pivot shift in patients with abnormal ALL. The logistic model for all variables analyzed with the results of the pivot shift test demonstrated that the ALL was the only variable with a statistically significant correlation in the model (p < 0.0005). CONCLUSION: MRI ALL abnormalities in patients with ACL injuries have a significant association with pivot shift test results in patients under anesthesia. The logistic model for high - grade pivot shift test results demonstrated that ALL abnormalities were the only variable with significant correlation. KEY POINTS: ⢠Evaluating the anterolateral ligament with MRI in acute anterior cruciate ligament injuries is useful to predict higher grades of pivot shift test in the moment of the arthroscopic reconstruction. ⢠An abnormal anterolateral ligament presented an odds ratio of 55 for high degrees of pivot shift. ⢠ALL MRI abnormalities association with knee instability is independent from other internal knee injuries.

Introducción: Las fracturas de la diáfisis femoral son lesiones que requieren gran energía y a menudo asocian otras lesiones. Este es el caso de las lesiones ligamentarias de rodilla, las cuales pueden pasar desapercibidas por el equipo médico tratante. El objetivo de nuestro trabajo es revisar la literatura existente sobre esta asociación lesional. Dentro de la misma se buscará la metodología diagnóstica utilizada y la incidencia de las lesiones ligamentarias. Materiales y métodos: Se realizó una búsqueda bibliográfica de forma sistematizada a través de los portales de búsqueda PubMed y Timbó. La búsqueda alcanzó un total de 3099 artículos y de acuerdo a los criterios de inclusión y exclusión se seleccionaron 15 trabajos. Resultados: Los diferentes artículos utilizaron examen físico bajo anestesia, radiografías en estrés, artroscopía o resonancia nuclear magnética para establecer el diagnóstico de las lesiones ligamentarias asociadas a las fracturas de diáfisis femoral. Un 22,5% de las fracturas femorales asoció lesión ligamentaria de rodilla, siendo la lesión del ligamento cruzado anterior el 34% de las lesiones reportadas. Discusión: Se evidencia una gran variabilidad en la incidencia de lesiones ligamentarias y de cuál es el ligamento más frecuentemente lesionado, yendo desde 5,3% a 52,5% en estudios tanto retrospectivos como prospectivos con bajos números de pacientes. Se plantea un algoritmo diagnóstico para los pacientes que puedan presentar esta asociación lesional, para evitar que los mismos pasen desapercibidos al equipo médico tratante. Logrando un diagnóstico precoz se puede mejorar el pronóstico de estos pacientes. Conclusión: De nuestra revisión se desprende que en el contexto de una fractura de diáfisis femoral un 22,5% de los pacientes presenta lesiones ligamentarias de rodilla con un 34% de compromiso del LCA. Sin embargo, estas cifras son muy variables en los distintos trabajos. Por esta razón, creemos necesario llevar a cabo un estudio prospectivo con mayor número de pacientes para lograr valorar la verdadera epidemiología de estas lesiones.
Introduction: Femoral shaft fractures require great energy and are often associated with other injuries. This is the case of knee ligament injuries, which can go unnoticed by the treating physician The objective of our work is to review the existing literature on this injury association. Within it, the diagnostic methodology used and the incidence of ligamentous injuries will be sought. Materials and methods: A bibliographic search was carried out in a systematic way through the search portals PubMed and Timbó. The search reached a total of 3099 articles and according to the inclusion and exclusion criteria, 15 works were selected. Results: The different articles used physical examination under anesthesia, stress radiographs, arthroscopy or magnetic resonance imaging to establish the diagnosis of ligamentous injuries associated with femoral diaphysis fractures. 22.5% of femoral fractures were associated with knee ligament injury, with anterior cruciate ligament accounting for 34% of reported injuries. Discussion: There is evidence of a great variability in the incidence of ligament injuries and which is the most frequently injured ligament, ranging from 5.3% to 52.5% in both retrospective and prospective studies with low numbers of patients. A diagnostic algorithm is proposed for patients who may present this lesional association, to prevent them from going unnoticed by the treating medical team. Achieving an early diagnosis can improve the prognosis of these patients. Conclusion: Our review shows that in the context of a femoral diaphysis fracture, 22.5% of patients present knee ligament injuries with 34% of ACL involvement. However, these figures are highly variable in the different studies. For this reason, we believe it is necessary to carry out a prospective study with a larger number of patients in order to assess the true epidemiology of these lesions.

CONTEXT: The number of pediatric anterior cruciate ligament reconstructions (ACLRs) occurring yearly increased almost 6-fold from 2004-2014. We find it interesting that limited recent data exist on rates of ACL injury and reconstruction in children and adolescents, especially in the context of COVID-19. OBJECTIVE: Given the effect of the COVID-19 pandemic on youth sports seasons and the postponement of many elective surgeries, we sought to examine the changes in rates of ACLR during this period. DESIGN: Retrospective cohort study. SETTING: This study used the Pediatric Health Information System (PHIS) database to identify eligible patients at PHIS-participating hospitals nationwide from January 2016-June 2021, with March 1, 2020, considered the start of the COVID-19 pandemic. PATIENTS OR OTHER PARTICIPANTS: Using Current Procedural Terminology codes, patients 18 years old and younger who underwent ACLR surgery were identified. MAIN OUTCOME MEASURE(S): Patient demographics and overall rates of surgery prepandemic and intrapandemic were compared. Data were analyzed using bivariate, mixed-model, and time series analyses. RESULTS: A total of 24â843 ACLRs were identified during this time period. In total, 1853 fewer surgeries than expected were performed after March 2020 given prepandemic trends. Intrapandemic demographics revealed an increase in the proportion of patients who identified as White and with private insurance and a decrease in the proportion who identified as Black and with public insurance. Also, the proportion of ACLRs by region shifted, with more surgeries performed in the Midwest and fewer in the Northeast. In the model adjusted for hospital-level variability, only race and insurance status remained significant. CONCLUSIONS: Based on prepandemic trends, fewer patients than projected underwent ACLR once the pandemic began, likely due to a combination of decreased rates of injury and delayed surgery.

Resumen: Las fracturas de calcáneo son las más frecuentes del tarso (3.5% de todas las fracturas). Afectan a adultos jóvenes, siendo más frecuentes en hombres (5.9:1). Por otro lado, las lesiones ligamentarias asociadas a fractura de calcáneo no son muy frecuentes. Presentamos un caso de un paciente de 39 años que sufrió entorsis de tobillo. Mostraba inestabilidad en flexión plantar e inversión. Radiografías mostraron una fractura de calcáneo. Durante la cirugía se evidenció una lesión completa del complejo ligamentario lateral. Se realizó la reducción y osteosíntesis asociada a la reconstrucción ligamentaria. Ante fracturas de calcáneo es importante corroborar la estabilidad del tobillo. La falta de diagnóstico en este tipo de lesiones puede generar inestabilidades crónicas.
Abstract: Calcaneal fractures are the most frequent of the tarsus (3.5% of all fractures). Young adults are mainly affected, being more frequent in men (5.9:1). On the other hand, ligament injuries associated with fracture of the calcaneus are very infrequent. We describe a case of a 39 year old patient who suffered ankle trauma. He presented instability in plantar flexion and inversion. A fracture of the calcaneus was diagnosed. During surgery, a complete lesion of the lateral ligament complex was found. The reduction and osteosynthesis associated with ligament reconstruction was performed. We consider important to confirm the stability of the ankle after a calcaneus fracture. Lack of diagnosis in this type of injuries can evolve into chronic instability.
RESUMO
The present research aims to compare the outcomes from the combined reconstruction of the anterior cruciate ligament (ACL) and of the anterolateral ligament (ALL) with the standard isolated ACL reconstruction in patients with chronic ACL injury. To do so, a meta-analysis was carried out to determine whether the combined ACL and ALL reconstruction would lead to a significant improvement in knee function according to the International Knee Documentation Committee (IKDC), the Lysholm test and KT-2000 evaluation scores and lower graft rupture rates in comparison with isolated reconstruction. To identify randomized controlled trials (RCTs) comparing the combined ACL and ALL reconstruction with the isolated ACL reconstruction, papers published between 2010 and 2019 were searched in the MEDLINE, EMBASE, SPORTDiscus, LILACS and Cochrane Central Register of Controlled Trials databases, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. The stability of the knee joint is only marginally improved with the combined reconstruction of ACL and ALL, and both reconstruction techniques show functional results. The main outcomes sought were patient function and graft stability and rupture rates after ACL reconstruction. Out of the 421 studies identified, 6 were included in our meta-analysis. Study quality (internal validity) was assessed using the Cochrane risk-of-bias tool; in general, the studies included presented moderate-quality evidence. The graft rupture rate was higher in patients undergoing isolated ACL reconstruction (relative risk, 0.22; 95% confidence interval, 0.12 to 0.41; p < 0.00001).

Resumo O objetivo da presentepesquisa é comparar, por meio de uma metanálise, os resultados da reconstrução combinada do ligamento cruzado anterior (LCA) e do ligamento anterolateral (LLA), comparado com a reconstrução isolada padrão, em pacientes com lesão crônica do ligamento cruzado anterior. Buscando alcançar o objetivo da pesquisa, foi realizada uma meta-análise para determinar se a combinação da reconstrução combinada LCA e LLA levaria àmelhoria significativa da função do joelho, medida pelos escores de avaliação International Knee Documentation Committee (IKDC), Lysholm, KT-2000 e menor taxa de ruptura do enxerto, em comparação com a reconstrução isolada. Para identificar ensaios clínicos randomizados (ECR) comparando a reconstrução combinada do LCA e LLA com a reconstrução isolada do LCA, foram pesquisados artigos publicados entre 2010 e 2019 nas bases MEDLINE, EMBASE, SPORTDiscus, LILACS e Cochrane Central RegisterofControlledTrials e seguiram os critérios de Itens de Relatórios Preferidos para Revisões Sistemáticas e Metanálises (PRISMA). A estabilidade da articulação do joelho é apenas marginalmente aprimorada com a reconstrução combinada de LCA e LLA, e ambas as técnicas de reconstrução mostram resultados funcionais. Os principais desfechos procurados foram a função do paciente e as taxas de estabilidade e ruptura do enxerto após a reconstrução do LCA. Dos 421 estudos identificados, 6estudos foram incluídos em nossa meta-análise. A qualidade do estudo (validade interna) foi avaliada usando o instrumento Cochrane risco-de-viés; em geral, foi encontrada uma qualidade moderada de evidências dos estudos incluídos. Os pacientes submetidos à reconstrução isolada do LCA mostraram maior taxa de ruptura do enxerto (RR 0,22; índice de confiança [IC]95%: 0,12-0,41; p< 0,00001).

BACKGROUND: One of the most common grafts used to repair anterior cruciate ligament (ACL) rupture is the hamstring tendon (HT) autograft. However, another proposed option to repair the ACL is the quadriceps tendon (QT) autograft. This study aimed to compare the pain and clinical results between patients with ACL injury treated with QT autograft and with HT autograft. MATERIALS AND METHODS: The Ethics and Investigation Committee of our institution approved the study. The patients were randomized into two groups: one group was treated with QT autograft and the other group was treated with HT autograft. The patients were evaluated preoperatively and postoperatively using the Lysholm-Tegner score, International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form, and visual analog scale (VAS), at 2 weeks and 1, 3, 6, and 12 months. RESULTS: A total of 28 patients with a primary ACL injury were included in the study. No significant differences in VAS pain, Lysholm knee and Tegner activity scale scores, and IKDC score between the HT and QT groups were observed at any time point. All patients had favorable outcomes and significantly improved evaluation scores. CONCLUSION: The patients treated with QT autograft had clinical results and post-operative pain similar to those of patients treated with HT autograft for ACL reconstruction.
ANTECEDENTES: Uno de los injertos más comúnmente usados para la reparación de una ruptura de ligamento cruzado anterior (LCA) es el autoinjerto de los tendones isquiotibiales. Sin embargo, otra opción propuesta para la reparación del LCA es el autoinjerto del tendón de cuadríceps. El objetivo de este estudio fue comparar el dolor y resultados clínicos en pacientes con lesión del LCA tratados con autoinjerto de cuadríceps y con autoinjerto de isquiotibiales. MATERIAL Y MÉTODOS: El Comité de Ética e Investigación de nuestra institución aprobó el estudio. Los pacientes fueron aleatorizados en dos grupos: un grupo fue tratado con autoinjerto del cuadríceps y el otro grupo con autoinjerto de isquiotibiales. Los pacientes fueron evaluados preoperatoriamente y postoperatoriamente usando la escala de Lysholm-Tegner, la International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form, y la Escala Visual Análoga (EVA), a las dos semanas, a 1, 3, 6 y 12 meses. RESULTADOS: Un total de 28 pacientes con lesión primaria de LCA fueron incluidos en el estudio. No hubo diferencias significativas en EVA, escala de Lysholm-Tengner y en IKDC entre los grupos de isquiotibiales y cuadríceps durante su evaluación. Todos los pacientes tuvieron evoluciones favorables y mejoraron de forma significativa sus escalas. CONCLUSIÓN: Los pacientes tratados con autoinjerto de tendón de cuadríceps tuvieron resultados clínicos y dolor postoperatorio similar a aquellos pacientes traídos con autoinjerto de isquiotibiales en la reconstrucción de LCA.

An osteochondral fracture of the posterolateral tibial plateau associated with an anterior cruciate ligament (ACL) injury in a 24-year-old boy is reported. Anterior cruciate ligament rupture is accompanied by bone contusions resulting from the impact of the posterolateral tibial plateau on the anterior part of the lateral femoral condyle. The osteochondral fracture of the posterolateral tibial plateau matched the site where the bone bruise is observed.
RESUMO
PURPOSE: Understanding the pathomechanics of a bicruciate injury (BI) is critical for its correct diagnosis and treatment. The purpose of this biomechanical study aims to quantify the effects of sequential sectioning of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) bundles on knee laxity. METHODS: Twelve cadaveric knees (six matched pairs) were used. Knee laxity measurements consisted of neutral tibial position, anterior-posterior translation, internal-external rotation, and varus-valgus angulation in different conditions: intact, ACL cut, incomplete BI (divided into two groups: anterolateral (AL) bundle intact or posteromedial (PM) bundle intact) and complete bicruciate tear. Data were collected using a Microscribe system at 0°, 30°, 60°, and 90° of knee flexion. RESULTS: In comparison to the intact knees, incomplete BI and complete BI showed a significant increase of total antero-posterior tibial translation. The largest significant increase was observed at 90° of flexion after a complete bicruciate resection (p < 0.001). A threshold difference greater than 15 mm from the intact could be used to identify a complete BI from an incomplete BI evaluating the total antero-posterior translation at 90°. All sectioned states had significant increases compared with the intact condition in internal-external rotation and varus-valgus stability at all tested flexion angles. CONCLUSION: Both incomplete and complete BI led to an important AP translation instability at all angles; however, full extension was the most stable position at all injured models. Total antero-posterior translation at 90° of knee flexion over 15 mm, in comparison to the intact condition, was indicative of a complete BI. Since the appropriate assessment of a combined ACL and PCL lesion remains a challenge, this study intends to assist its diagnosis. As BI's main antero-posterior instability occurred at 90°, a total antero-posterior drawer test is proposed to evaluate BI in the clinical setting. Total antero-posterior translation at 90° > 15 mm, in comparison to the intact condition or the contra-lateral non-injured knee, can be used to identify a complete from an incomplete BI.

PURPOSE: An uncommon technique for bicruciate ligament reconstruction involving simultaneous tensioning of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) grafts with ACL graft fixation first has been pointed out as superior to the "gold-standard" PCL graft fixation first. The purpose of this study was to compare tibiofemoral biomechanics between ACL fixation first and PCL fixation first in a simultaneous tensioning protocol for bicruciate ligament reconstruction. METHODS: 12 fresh-frozen cadaveric knees (six matched pairs) were tested using a custom testing system. Neutral tibial position representing tibiofemoral orientation, anterior-posterior (AP) tibial translation, varus-valgus laxity, and internal-external rotation were measured using a Microscribe 3DLX at 0°, 30°, 60°, and 90° of knee flexion. The following knee conditions were evaluated: intact, bicruciate deficient and following bicruciate reconstruction. A simultaneous tensioning protocol was used for bicruciate reconstruction and PCL fixation first was compared to ACL fixation first. PCL graft fixation was always performed at 90° of flexion and ACL graft fixation was always performed at full extension. RESULTS: ACL fixation first achieved a tibiofemoral orientation closer to the intact knee than PCL fixation first at 90° flexion (1.8 ± 1.6 mm versus 6.1 ± 3.2 mm, p = 0.016). PCL fixation first had a larger decrease in AP translation than ACL fixation first at 30° flexion (64.6 ± 3.5% vs. 58.3 ± 2.4%, p = 0.01). No significant differences were found for varus/valgus, external-internal rotation decrements after bicruciate reconstruction nor for AP translation, varus/valgus and internal/external rotation increase after bicruciate lesion comparing ACL fixation first to PCL fixation first. CONCLUSION: Bicruciate ligament reconstruction using a simultaneous tensioning protocol with ACL fixation first resulted in a closer to normal tibiofemoral orientation. This study will help guide surgeons in decision making for the graft tensioning protocol and fixation sequence in a bicruciate ligament reconstruction. LEVEL OF EVIDENCE: V therapeutic study.

Lateral hindfoot pain associated with stage 2 to 3 adult-acquired flatfoot is often attributed to subfibular impingement. Preoperative magnetic resonance imaging (MRI) is generally performed to assess the extent of degeneration within the posterior tibial tendon, attenuation of medial soft tissue constraints, and degeneration of hindfoot and/or ankle articulations. The purpose of this study is to determine the incidence of lateral collateral ligament disease/injury associated with stages 2 and 3 adult-acquired flatfoot. The subjects were identified using a searchable computerized hospital database between 2015 and 2017. Stage 2 or 3 adult-acquired flatfoot deformity was confirmed in patients via chart review and MRI analysis. Lateral ankle ligament injury was confirmed using patient MRI results per the hospital radiologist and documented within the patients' chart. Inclusion criteria required that patients be diagnosed with Johnson and Strom stage 2 or 3 flatfoot deformity with documented lateral ankle pain and that preoperative MRI scans be available with the radiologist's report. Patient exclusion criteria included patients <18 years of age, patients with flatfoot deformity caused by previous trauma, tarsal coalition, neuropathic arthritis, patients with previous surgery, or patients with incomplete medical records. In total, 118 patients were identified with these parameters. Of the 118 patients, 74 patients (62.7%) had documented lateral ankle ligament injury on MRI. Of the 77 patients with stage 2 adult-acquired flatfoot, 55 (71.4%) had confirmed lateral ankle ligament injury on MRI. Of the 41 patients with stage 3 adult-acquired flatfoot, 19 (46.3%) had confirmed lateral ankle ligament injury on MRI. This study demonstrates a relatively high incidence of lateral ligament disease associated with adult-acquired flatfoot deformity. These findings might have long-term implications regarding ankle arthritis after surgical management of adult-acquired flatfoot.

OBJECTIVE: To compare knee isokinetic performance six months after reconstruction of the anterior cruciate ligament using grafts from either the patellar tendon or the hamstrings among patients who underwent the same rehabilitation protocol. METHODS: Thirty-four patients were evaluated (17 with grafts from the patellar tendon and 17 with grafts from the hamstrings). Operated and non-operated knees were compared with regards to the variables of peak torque, work and the hamstring/quadriceps relationship at velocities of 60º/s and 180º/s and power of 180º/s after six months of surgery. RESULTS: The patients with ACL reconstruction using the patellar tendon (BPTB) showed quadriceps deficits for all variables, but the flexor musculature was balanced. In the hamstring group, both the extensors and the flexors showed deficits for the variables analyzed, except for hamstring power at 180º/s. CONCLUSION: Patients in the patellar tendon group had a greater quadriceps deficit compared with those in the hamstrings group. Patients in the hamstrings group had a greater muscular deficit in the flexor mechanism compared with the contralateral knee. An unbalanced H/Q ratio was observed regardless of graft type, but this was more evident in the BPTB group.

Contexto: las roturas del ligamento cruzado anterior (LCA) en pacientes con fisis abiertas representan el 3,3% de las roturas del LCA, En el tratamiento de las roturas intersticiales del LCA en pacientes con fisis abiertas existe controversia en la elección entre tratamiento conservador y tratamiento quirúrgico. Objetivo: analizar la reconstrucción del ligamento cruzado anterior LCA con fisis abierta en el Servicio de Ortopedia y Traumatología del Hospital de Especialidades FFAA No 1. Sujetos y métodos: estudio retrospectivo en pacientes sometidos a cirugía artroscópica para tratamiento de lesión del LCA con fisis abiertas, en el periodo enero 2012 y abril de 2015. En relación al tratamiento, se utilizó la técnica transfisaria completa (monotúnel); el injerto se fija al fémur con un endobotón y a la tibia con un tornillo de interferencia; el injerto fue obtenido del músculo semitendinoso. Resultados: fueron intervenidos 9 pacientes de sexo masculino, con edades entre 13 y 16 años, con lesiones del ligamento cruzado anterior en rodilla derecha (n=7, 78%) e izquierda (n=2, 22%); la ruptura del menisco es la lesión asociada más frecuente. Conclusión: las roturas del LCA con fisis abiertas son cada vez más frecuentes en la actualidad. La reconstrucción del LCA debe ser precoz para evitar lesiones condrales y meniscales. Se recomienda el tratamiento quirúrgico por los óptimos resultados clínicos y funcionales. (AU)
Background: anterior cruciate ligament (ACL) tears in open physis patients represent 3.3% of ACL tears. In the treatment of ACL interstitial tears in patients with open physis, there is controversy in the choice between conservative treatment and surgical treatment. Objective: to analyze the reconstruction of the anterior cruciate ligament ACL with open physis in the Orthopedics and Traumatology Service of the Specialty Hospital FFAA No 1. Subjects and methods: retrospective study in patients undergoing arthroscopic surgery for treatment of ACL injury with open physis, in the period January 2012 and April 2015. In relation to the treatment, the complete transfusion technique (monotunnel) was used; the graft is fixed to the femur with an endobotton and to the tibia with an interference screw; the graft was obtained from the semitendinous muscle. Results: were operated on 9 male patients, with ages between 13 and 16 years, with injuries of the anterior cruciate ligament in the right knee (n = 7, 78%) and left (n = 2, 22%); the rupture of the meniscus is the most common associated lesion. Conclusion: ACL tears with open physis are becoming more frequent today. The reconstruction of the ACL must be early to avoid chondral and meniscal lesions. Surgical treatment is recommended for optimal clinical and functional results. (AU)
