RESUMEN

PURPOSE: To compare return to sport and knee function 1 year after anterior cruciate ligament (ACL) reconstruction using autografts with and without vancomycin presoaking. METHODS: A case-control study based on a retrospective analysis of prospective data included athletes over the age of 16 operated from 2012 to 2018 for ACL reconstruction. There were two groups of patients due to a change in treatment protocols: Group 1 « without vancomycin ¼ before November 2016 and Group 2 « with vancomycin¼ after this date. In Group 2, the graft was soaked in a vancomycin solution for 10 min and then fixed into the bone tunnels. The primary evaluation criterion was the return to sport 1 year after surgery. The secondary criteria were various knee scores. The number of patients needed to perform a non-inferiority study was calculated. RESULTS: 1674 patients fulfilled the selection criteria, 1184 in Group 1 and 490 in Group 2. The series included 1112 men and 562 women, mean age 30 ± 9.7 years, 68 professional athletes, 674 competitive athletes and 932 recreational athletes. While seven patients presented with post-operative septic arthritis in Group 1, this complication was not found in Group 2. No significant difference was identified in the return to running between the two groups 1 year after surgery (75.9% vs. 76.1%, n.s.). Significantly more of the patients in Group 2 returned to their preinjury sport (p = 0.04). Knee function was comparable between the groups. CONCLUSION: Vancomycin-soaked grafts during ACL reconstruction reduce the risk of post-operative infection of the knee without affecting the return to sport or knee function. LEVEL OF EVIDENCE: III.

RESUMEN

BACKGROUND: Patellofemoral arthroplasty (PFA) is an alternative to a total knee arthroplasty (TKA) in patients with severe isolated patellofemoral osteoarthritis. The main goal of this study was to determine the revision rate of the Hermes™ (Ceraver) anatomical unconstrained PFA. METHODS: A retrospective single surgeon study was performed including all patients operated for PFA between 1997 and 2015. A standardized procedure was used to perform PFA with one type of prosthesis. All patients in the study were contacted at the final follow-up. The main judgment criterion was the annual rate of revision. Secondary criteria were the severity of anterior knee pain on a numerical scale (0-10) and functional scores (IKS and AKP scores). RESULTS: During this period, PFA was performed in 64 patients (74 PFA), 52 women/12 men, mean age at surgery 59.6 ±â€¯11.8 (31.3-82.1) years old. Four patients (5.4% of PFA) were lost to follow-up. Mean follow-up for the remaining 70 PFA was 7.5 ±â€¯7.1 (2-20) years. TKA was required in 10 (14.3%) patients after a mean 5.4 ±â€¯3.4 (1-9.3) years. The annual rate of revision was two-percent CI95% [1.1-3.7%] if TKA was considered to be the defining event and 3.1% CI95% [1.9-5.1%] for all types of revision (partial/total PFA replacement or TKA). Patients who underwent revision were significantly younger. After a mean eight (2-20) years of follow-up, mean anterior pain, the IKS and AKP scores improved significantly. CONCLUSION: In this series, 78.6% of patients with a Hermes™ PFA did not require any revision after a follow-up of between two and 20 years. LEVEL OF EVIDENCE: Level IV - retrospective study.

RESUMEN

BACKGROUND: The decision to return to sport following anterior cruciate ligament (ACL) reconstruction should not only be based on time since surgery. This study aimed to assess, using isokinetic and neuromuscular (hops) testing in a large group, postoperative objective functional recovery of the knee. The secondary objective was to determine the relationship between psychological, functional scores, and these postoperative tests. METHODS: This prospective study included athletes who underwent surgery between 2013 and 2016 for an isolated full-thickness ACL tear. They received a complete evaluation of functional performance of the knee by isokinetic tests performed on a dynamometer to measure quadriceps and hamstring strength, and neuromuscular assessment based on single-leg hop tests. The main judgment criterion was satisfactory functional recovery (yes/no) defined as a difference of ≤10% both in the quadriceps 60°/s and the single hop at a minimum of four months of follow-up. RESULTS: A total of 234 athletes were analyzed. The mean age was 28.4 ±â€¯8.6 years. At 6.5 ±â€¯1.7 months mean follow-up, 44 (18.5%) patients had satisfactory functional recovery of the knee. The correlations between isokinetic/hop tests and the different scores were variable. During follow-up, two patients presented with a graft tear and two with a contralateral ACL tear, all in the group with unsatisfactory functional recovery. CONCLUSION: At a mean of six months after ACL reconstruction, objective functional recovery of the knee was generally unsatisfactory and this seemed to be a risk factor for recurrent tears. LEVEL OF EVIDENCE: IV; case series.

RESUMEN

BACKGROUND: The rate of septic arthritis in the knee after anterior cruciate ligament (ACL) reconstruction varies in the literature but is generally less than 1%. It has been reported to be higher in professional athletes (5.7%). PURPOSE: The primary goal was to evaluate the rate of septic arthritis after ACL reconstruction in professional athletes compared with other patients. The secondary goals were to analyze the risk factors; increased cost of infections; return to sport, satisfaction, and functional results at 1-year follow-up; and resolution rate of infections at final follow-up. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: This retrospective analysis of prospective data included a continuous series of patients who underwent isolated ACL reconstruction between 2012 and 2016. The main outcome criterion was the development of intra-articular infections in the operated knee. An infection was suggested clinically (knee pain with fever and/or chills) and confirmed bacteriologically in deep tissue samples obtained during revision surgery. All infected patients underwent an emergency reoperation with lavage and debridement along with dual antibiotic therapy first by an intravenous route and then orally for 6 weeks. RESULTS: A total of 1809 of 1859 patients included in the cohort during this period fulfilled inclusion criteria; there were 1632 (90.2%) who underwent primary reconstruction and 177 (9.8%) who underwent revision. The series included 1249 (69%) men and 560 (31%) women, with a mean age of 29.1 ± 9.8 years. Ninety-eight percent of the patients participated in a sport, including 90 (5.0%) at a professional level and 712 (39.4%) competitively. Septic arthritis of the knee developed after a mean 15.7 ± 5.5 days in 7 (0.38%) patients: 5 of 1632 (0.31%) who underwent primary reconstruction and 2 of 177 (1.13%) who underwent revision. Septic arthritis did not develop in any professional or competitive athletes; all affected patients were recreational athletes ( P = .02). The risk factors identified for the development of septic arthritis on multivariate analysis were prior knee surgery (odds ratio [OR], 15; P = .002) and hemarthrosis during the immediate postoperative period (OR, 127.2; P = .002). There were no recurrent infections after a mean follow-up of 2.8 ± 1.2 years. CONCLUSION: None of the professional athletes in this cohort had septic arthritis after ACL reconstruction. There are no particular precautions to be taken in this population. The risk factors identified for the development of septic arthritis on multivariate analysis were prior knee surgery and hemarthrosis during the immediate postoperative period. Similar to all studies published on the subject, there were very few infected patients, which limits the identification of risk factors. REGISTRATION: NCT02511158 (ClinicalTrials.gov identifier).

RESUMEN

PURPOSE: To describe the clinical results of patients who underwent surgical treatment for a intra-osseous tibial tunnel cyst on a bioabsorbable interference screw following anterior cruciate ligament reconstruction (ACL). METHODS: This retrospective study included all patients who underwent surgery between 2004 and 2016 for an intra-osseous tibial tunnel cyst on bioabsorbable interference screw following ACL reconstruction. The diagnosis was suggested clinically by pretibial pain at the incision site, sometimes associated with a palpable subcutaneous nodule and then confirmed on MRI. The first stage of surgery included exploratory arthroscopy followed by open excision/curettage of the cyst and then the tunnel was filled. The main criterion for outcome was a clinically normal knee (no pain, 0-120 range of motion, stable, with no effusion) at 6 months of follow-up. RESULTS: This series included 53 patients, mean age 35.3 ± 9.9 years old w ith a mean 4.6 ± 3.1 years (between 3.1 months and 19 years) of follow-up after ligament reconstruction. The tibial screw was completely absorbed in 9/53 (17%) of patients, and fragmented in 22/53 (41.5%). At the 6-month follow-up, 42/53 (79.2%) patients had a normal knee, 11/53 (20.8%) persistent pain in the cyst area, 52/53 (98.1%) normal range of motion and 53 (100%) a stable knee. A recurrent cyst developed at 2 years of follow-up in one patient. CONCLUSION: Complete absorption of a bioabsorbable interference screw is long, increasing the risk of developing intra-osseous tibial cysts during this period. The development of new materials with improved absorption properties is needed. LEVEL OF EVIDENCE: IV-Retrospective study.

RESUMEN

BACKGROUND: Successful return to sport after anterior cruciate ligament (ACL) reconstruction requires optimal physical and psychological recovery. The main validated tool to quantify a patient's psychological readiness to return to sport after this surgery is the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale. PURPOSE: The primary aim was to analyze the progression of the ACL-RSI score from preoperatively to 2-year follow-up. A secondary goal was to identify the factors associated with returning to the same preinjury sport. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: This prospective study included athletes older than 16 years in all sports and levels of play who underwent primary and revision isolated ACL reconstruction from 2012 to 2015 and responded to all study questionnaires at 2-year follow-up. The primary outcome was the ACL-RSI score obtained preoperatively and at 4-month, 6-month, 1-year, and 2-year follow-up. The secondary outcomes were return to sport (running and the same preinjury sport) and various functional scores. The optimal threshold value of the ACL-RSI score for returning to the same preinjury sport was determined with the receiver operating characteristic curve. Multivariate analysis was performed to identify other factors associated with returning to the same sport at 2-year follow-up. RESULTS: A total of 681 patients were analyzed (467 men, 214 women; mean age, 30.2 ± 9.5 years); 298 (43.8%) patients were professional or competitive athletes. The ACL-RSI score improved significantly over time: 41.3 ± 25.4 preoperatively, 55.1 ± 21.3 at 4 months, 58.3 ± 22.3 at 6 months, 64.7 ± 24.2 at 1 year, and 65.2 ± 25.3 at 2 years (P < .00001). At 2-year follow-up, 74.9% of patients had returned to running and 58.4% to their same preinjury sport. The ACL-RSI score was significantly higher in patients who had returned to sport and in those who returned to the same level of play or higher (P < .00001). The optimal ACL-RSI score threshold to return to the same sport at 2-year follow-up was ≥65. Multivariate analysis showed that the predictive factors of returning to the same preinjury sport at 2-year follow-up were primary reconstruction, professional or competitive level of play, an ACL-RSI score ≥60 at 6-month follow-up, and the absence of postoperative complications. CONCLUSION: The psychological ACL-RSI score improved regularly after ACL reconstruction and was strongly and significantly associated with return to sport.

RESUMEN

BACKGROUND: The aim of this controlled multicenter study is to evaluate the clinical and radiologic outcomes of primary total knee arthroplasty (TKA) using single-use fully disposable and patient-specific cutting guides (SU) and compare the results to those obtained with traditional patient-specific cutting guides (PSI) vs conventional instrumentation (CI). METHODS: Seventy consecutive patients had their TKA performed using SU. They were compared to 140 historical patients requiring TKA that were randomized to have the procedure performed using PSI vs CI. The primary measure outcome was mechanical axis as measured on a standing long-leg radiograph using the hip-knee-ankle angle. Secondary outcome measures were Knee Society and Oxford knee scores, operative time, need for postoperative transfusion, and length of hospital stay. RESULTS: The mean hip-knee-ankle value was 179.8° (standard deviation [SD] 3.1°), 179.2° (SD 2.9°), and 178.3° (SD 2.5°) in the CI, PSI and SU groups, respectively (P = .0082). Outliers were identified in 16 of 65 (24.6%), 15 of 67 (22.4%), and 14 of 70 (20.0%) knees in the CI, PSI, and SU group, respectively (P = .81). There was no significant difference in the clinical results (P = .29 and .19, respectively). Operative time, number of unit transfusion, and length of hospital stay were not significantly different between the 3 groups (P = .45, .31, and 0.98, respectively). CONCLUSION: The use of an SU in TKA provided similar clinical and radiologic results to those obtained with traditional PSI and CI. The potential economic advantages of single-use instrumentation in primary TKA require further investigation.

RESUMEN

PURPOSE: The main goal of this study was to propose and validate a tool to quantify the psychological readiness of athletes to return to sport following traumatic shoulder instability and conservative or surgical management. METHODS: «Knee¼ was replaced by the term «shoulder¼ in the Anterior Cruciate Ligament-Return to Sport after Injury scale. This pilot test of the Shoulder Instability-Return to Sport after Injury scale (SIRSI) was performed in a group of athletes who underwent surgery for post-traumatic chronic anterior shoulder instability. The final version was then validated according to the international COSMIN methodology. A retrospective study was performed including all rugby players who had reported an episode of instability between 2012 and 2013. The WOSI and the Walch-Duplay scales were used as reference questionnaires. RESULTS: Sixty-two patients were included, mean age 26 ± 5.2 years old, 5 women/57 men. Patients were professional or competitive athletes (70.9%) and followed-up for 4.6 ± 1.6 years after the first episode of shoulder instability. Shoulder surgery was performed in 30/62 (48.4%) patients, a mean 1.6 ± 1.2 years after the first episode of instability. The SIRSI was strongly correlated with the reference questionnaires (r = 0.80, p < 10-5). The mean SIRSI score was significantly higher in patients who returned to play rugby (60.9 ± 26.6% vs 38.1 ± 25.6%, p = 0.001). The internal consistency of the scale was high (α = 0.96). Reproducibility of the test-retest was excellent (ρ = 0.93, 95% CI [0.89-0.96], p < 10-5). No ceiling/floor effects were found. CONCLUSION: The SIRSI is a valid, reproducible scale that identifies patients who are ready to return to the same sport after an episode of shoulder instability, whether they undergo surgery or not.

RESUMEN

BACKGROUND: Few studies have reported the return-to-sport rate at 1-year follow-up after primary and revision anterior cruciate ligament (ACL) reconstruction. PURPOSE: To compare the return-to-sport rate 1 year after primary and revision ACL reconstruction in the same cohort according to 2 modalities: any kind of sport and the patient's usual sport at the same level as before the injury. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A single-center, prospective cohort study of patients undergoing ACL reconstruction (French prospective Acl STudy [FAST]) was begun in 2012. A comparative study was performed based on a retrospective analysis of data collected prospectively. Included were all athletes aged 18 to 50 years who underwent primary or revision isolated ACL reconstruction between 2012 and 2014. Two groups were formed: primary reconstruction and revision reconstruction. The main criterion was return to sport at 1-year follow-up (yes/no); secondary criteria were return to the usual sport at 1-year follow-up, knee function (International Knee Documentation Committee [IKDC] and Knee injury and Osteoarthritis Outcome Score [KOOS] scores), and psychological readiness (ACL-Return to Sports after Injury [ACL-RSI] score) at 6 months and 1 year. RESULTS: A total of 552 patients (primary reconstruction group: n = 497, revision reconstruction group: n = 55) were included in the study. There were 373 men and 179 women (mean [±SD] age, 30.2 ± 8.4 years). No significant difference in the return-to-sport rate was found between the 2 groups at 1-year follow-up (primary reconstruction group: 90.9%, revision reconstruction group: 87.3%; P = .38), but patients in the primary reconstruction group resumed their usual sport significantly more often (primary reconstruction group: 63.6%, revision reconstruction group: 49.1%; P = .04). Eight (1.4%) retears occurred during a new sport-related injury within a mean 8.9 ± 2.9 months: 7 (1.4%) in the primary reconstruction group and 1 (1.8%) in the revision reconstruction group ( P = .8). At 1-year follow-up, functional scores were significantly better in the primary reconstruction group for subjective IKDC (82.6 ± 13.3 vs 78.4 ± 16.6; P = .04); KOOS Symptoms/Stiffness (73.3 ± 15.2 vs 67.7 ± 19.6; P = .02), Activities of Daily Living (96.3 ± 6.4 vs 94.3 ± 9.1; P = .04), Sport (79.7 ± 19.1 vs 69.1 ± 24.8; P = .0004), and Quality of Life (69.6 ± 22.7 vs 54.7 ± 24.8; P < .00001) subscales; and ACL-RSI (65 ± 23 vs 49.5 ± 24.8; P < .00001). On multivariate analysis, patients who were more likely to resume their usual sport at 1 year were high-level players (odds ratio [OR], 2.2) who underwent primary reconstruction (OR, 2.0) and had better KOOS Quality of Life (OR, 1.7) and subjective IKDC (OR, 2.1) scores at 6-month follow-up without complications or retears during the first postoperative year (OR, 2.6). CONCLUSION: At 1-year follow-up, there was no significant difference in the return-to-sport rate between primary and revision ACL reconstruction. Patients who underwent primary reconstruction returned to their usual sport significantly more often. TRIAL REGISTRATION: NCT02511158 ( ClinicalTrials.gov identifier).

RESUMEN

The main objective of this review was to present a synthesis of the current literature in order to provide a useful tool to clinician in radiologic analysis of the meniscus. All anatomical descriptions were clearly illustrated by MRI, arthroscopy, and/or drawings. The value of standard radiography is extremely limited for the assessment of meniscal injuries but may be indicated to obtain a differential diagnosis such as osteoarthritis. Ultrasound is rarely used as a diagnostic tool for meniscal pathologies and its accuracy is operator-dependent. CT arthrography with multiplanar reconstructions can detect meniscus tears that are not visible on MRI. This technique is also useful in case of MRI contraindications, in postoperative assessment of meniscal sutures and the condition of cartilage covering the articular surfaces. MRI is the most accurate and less invasive method for diagnosing meniscal lesions. MRI allows confirming and characterizing the meniscal lesion, the type, the extension, its association with a cyst, the meniscal extrusion, and assessing cartilage and subchondral bone. New 3D-MRI in three dimensions with isotropic resolution allows the creation of multiplanar reformatted images to obtain from an acquisition in one sectional plane reconstructions in other spatial planes. 3D MRI should further improve the diagnosis of meniscal tears.

RESUMEN

BACKGROUND: One of the most frequent demands from athletes after rotator cuff tear repair is to return to sport, if possible at the same level of play. PURPOSE: The main goal of this study was to determine the rate of return to sport after treatment of rotator cuff tears. STUDY DESIGN: Meta-analysis and systematic review. METHODS: The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to perform this systematic review and meta-analysis of the results in the literature, as well as for the presentation of results. A search of the literature was performed on the electronic databases MEDLINE, Scopus, EMBASE, and the Cochrane Library. The quality of the included studies was evaluated according to the MINORS (Methodological Index for Nonrandomized Studies) checklist. Inclusion criteria were studies in English evaluating return to sport after treatment of traumatic, degenerative, partial or full-thickness rotator cuff tears in patients practicing a sport regularly, whatever the level, all ages and sports included. The main judgment criterion was the number of patients who returned to a sports activity after treatment of a rotator cuff tear. The criterion was analyzed in 2 ways: return to sport (yes/no) and the level of play (identical or higher/lower level). RESULTS: Twenty-five studies were reviewed, including 859 patients (683 athletes), all treated surgically after a mean follow-up of 3.4 years (range, 0.3-13.4 years). The level of sports was recorded in 23 studies or 635 (93%) athletes and included 286 competitive or professional athletes and 349 recreational athletes. The most commonly practiced sports were baseball (224 participants), tennis (104 participants), and golf (54 participants). The overall rate of return to sport was 84.7% (95% CI, 77.6%-89.8%), including 65.9% (95% CI, 54.9%-75.4%) at an equivalent level of play, after 4 to 17 months. Of the professional and competitive athletes, 49.9% (95% CI, 35.3-64.6%) returned to the same level of play. CONCLUSION: Most recreational athletes return to sports at the same level of play as before their injury, but only half of professional and competitive athletes return to an equivalent level of play.

RESUMEN

The association of an anterior cruciate ligament (ACL) tear and a posterior cruciate ligament (PCL) injury is rare in athletes, and to our knowledge it has never been described in a professional rugby player. We report the case of a 27-year-old international professional rugby player who presented with an ACL tear associated with chronic posterior laxity on a former PCL tear. The procedure associated arthroscopic ACL and PCL reconstruction in a one-stage operation with two autografts, bone-patellar tendon-bone and hamstring tendon, respectively. At 7 months postoperatively, the patient had returned to playing rugby at the same level of play. The therapeutic strategy successfully met the established goals of returning to sports at the same level of play with excellent functional results after 2 years of follow-up. A literature review was performed via PubMed. The inclusion criteria were the studies in English language, assessing the return-to-sport after bicruciate ligament reconstruction in athletes. Eight studies were included in analysis. Only one study has focused on the return-to-sport in 24 competitive athletes and two other studies have included 1 professional athlete each. The overall rate of the return-to-sport after bicruciate reconstruction varied between 100% and 50%.

RESUMEN

BACKGROUND: An understanding of the epidemiology of shoulder dislocation/subluxation in rugby union players could help develop targeted prevention programmes and treatment. We performed a multiyear epidemiological survey of shoulder dislocation/subluxation in a large cohort of rugby players. METHODS: A descriptive epidemiological study was performed prospectively for five playing seasons (2008-2013) in all players licensed in the French Rugby Union. Rugby players were categorised into five groups by age. The player and the team physician reported the injury to the club insurance company if it occurred during training or a match. The goals of the study were to define the rate, type and causes of shoulder dislocation/subluxation. RESULTS: 88,044 injuries were reported, including 1345 (1.5%) episodes of dislocation/subluxation in 1317 men and 28 women, mean age 22.5±5.9 years. About 10/10,000 men and 5/10,000 women reported an episode of shoulder dislocation/subluxation per season, including 83/10,000 senior professionals, 17/10,000 senior amateurs, 21/10,000 juniors, 12/10,000 cadets and <1/10,000 rugby school players. Shoulder dislocation/subluxation was significantly more frequent in senior and junior players (p<0.001). Injuries mainly occurred during a match (66%) in the middle of the season (44%). The most frequent playing position was forwards (56%) and the main mechanism was tackling (69%). When reported, the history of recurrence was found in 66% of injured players, fractures in 22% and acromioclavicular injury in 6.7%. Nerve injury was associated with shoulder dislocation in 6% of cases. CONCLUSIONS: Senior professionals and junior male forward rugby players with a history of shoulder dislocation/subluxation should receive special attention from sports medicine professionals and orthopaedic surgeons.

RESUMEN

PURPOSE: We aimed to determine the rate of local recurrence, the rate of postoperative complications, and the functional outcome at final follow-up of surgical and nonsurgical treatment approaches for pigmented villonodular synovitis (PVNS) of the knee. METHODS: Medline, Embase, and the Cochrane Library were systematically searched for studies that reported the results of treatment for any type of PVNS between January 1, 1950, and August 1, 2013. Two authors extracted the data independently using predefined data fields including study quality indicators. RESULTS: Sixty studies (1,019 patients) met the inclusion criteria. Thirty-five presented data on the treatment of localized pigmented villonodular synovitis (LPVNS), 40 on diffuse pigmented villonodular synovitis (DPVNS), 1 on extra-articular LPVNS, and 7 on DPVNS with extra-articular involvement. Many therapeutic options were reported. Depending on these options, DPVNS recurred in 8% to 70% of the series and LPVNS recurred in 0% to 8% of the series. For LPVNS, the 2 most-reported options were open localized synovectomy and arthroscopic local synovectomy. Between these 2 courses of treatment, no difference was found in terms of local recurrence (8.7% for open synovectomy and 6.9% for arthroscopic synovectomy) and postoperative complications (<1% for open synovectomy and 0% for arthroscopic synovectomy). For DPVNS, the 2 most-reported options were open total synovectomy and arthroscopic total synovectomy. Between these 2 courses of treatment, no difference was found in terms of local recurrence (22.6% for open synovectomy and 16.1% for arthroscopic synovectomy). However, we found a lower rate of reported complications between open synovectomy (19.3%) and arthroscopic synovectomy (0%). Internal irradiation or external beam radiation as an adjuvant treatment to surgical synovectomy seemed to decrease the rate of local recurrence in DPVNS cases with a high risk of recurrence. Finally, we found a great heterogeneity in the way the functional results were reported, and no valid conclusion could be made based on the data we extracted. CONCLUSIONS: We found no difference in local recurrence rates after open or arthroscopic surgery for either LPVNS or DPVNS. However, a lower rate of postoperative complications was reported after arthroscopic surgery for DPVNS. LEVEL OF EVIDENCE: Level IV, systematic review of Level IV therapeutic studies.

RESUMEN

Habitual patellar dislocations are rare in adults. Treatment is difficult, and often associated with significant morbidity. A 30-year-old man, construction worker, presented a habitual patellofemoral dislocation which was caused by direct trauma to the knee as a child. Clinical examination showed a 3 cm leg-length discrepancy with no rotational deformities. The patient had a limp and loss of function; the patella was dislocated laterally and had locked at 20° of flexion with a range of motion of 0°/0°/30°. Open surgery was performed associating lateral retinacular release, reconstruction of the medial patellofemoral ligament with an ipsilateral gracilis tendon graft. The postoperative course was simple with no complications. Four months after surgery the patient has begun working normally. At the final 50-month clinical follow-up, knee range of motion was 0°/0°/130°, and functional results were excellent on clinical assessment scores of Kujala, Lysholm, and subjective IKDC. MPFL reconstruction alone seems effective in habitual posttraumatic patellar dislocation in adults without any associated bone anomalies.

RESUMEN

BACKGROUND: Although guidelines based on expert opinions have been developed for the immediate management and return to play of athletes after a concussion, data are lacking on this issue. OBJECTIVES: Evaluate a standardized management of brain concussion among rugby players to prevent the recurrence. PATIENTS AND METHODS: A prospective study was performed from September 2009 to June 2012. All rugby players who had a concussion when playing rugby were included. Patients were managed by a specialized hospital team with a specific protocol developed in collaboration with the medical staff of the rugby clubs included in the study. The series included 35 rugby players, with 23 professionals and 12 high-level players, 30 men and 5 women, mean age 23.1 ± 5.5 years old. The median number of previous concussions was 2 (0-30) episodes. According to the Cantu concussion severity classification, 3 athletes were grade 1, 12 were grade 2 and 20 were grade 3. None of the injured athletes was lost to follow-up. The primary endpoint was the occurrence of a new concussion within 3 months after the first in patients who returned to rugby. RESULTS: Thirty-three patients returned to rugby after a mean 22.1 ± 10 days. The recurrence rate within 3 months was 2/33 (6.1%). The median delay before returning to rugby was 21 (7-45) days. Factors associated with a delayed return to play were young age, initial loss of consciousness, severity Cantu grade 3 and post-concussive syndrome of more than 5 days. Analysis of two failures showed that the initial injury was grade 3 and that both were professional athletes and had a history of concussion. CONCLUSIONS: This prospective study validated the study protocol for the management of concussion in rugby players.

RESUMEN

PURPOSE: The main purpose of this study was to investigate whether judo could be practised after joint replacement. METHODS: Two hundred and twelve questionnaires were sent to Judokas licensed at the French Judo Federation, over the age of 60, with at least a black belt 6th Dan. Out of 83 responses, 38 individuals, mean age 72.8 ± 7.9 years old, had at least one implant. The survey identified 36 total hip arthroplasties (THA) in 27 patients, 10 total knee arthroplasties (TKA) in 8 patients and 3 total shoulder arthroplasties (TSA) in 3 patients. The main evaluation criterion was the return to judo after joint replacement. Secondary criteria were the level of judo after surgery, rate of surgical revision at the final follow-up and the level of patient satisfaction. RESULTS: Twenty-nine out of 38 patients who underwent joint replacement returned to judo practice (76.3 %) a mean 4.1 ± 2.9 months after surgery. On the other hand, all patients stopped competitive judo. The surgeon recommended 65.8 % of these patients to stop practising judo. There were 2 surgical revisions in the THA group (5.5 %) for loosening at 6 and 9 years of follow-up. No dislocations or fractures were reported at the final follow-up. Thirty-two patients (84.2 %) were satisfied with their implant. CONCLUSION: The practice of judo does not seem to be limited by joint replacement. A clinical and radiological study should be performed to confirm these results.
