RESUMEN

Objectives: The purpose of our study was to compare (1) posterior cruciate ligament (PCL) laxity, (2) patient-reported outcome, and (3) complications after the all-inside PCL reconstruction (Al-PCLR) technique and conventional PCLR (CON-PCLR) technique at minimum 2-year follow-up. We hypothesized that AI-PCLR and CONV-PCLR would yield similar results in PCL laxity, patient-reported outcomes, and complications. Method: A retrospective cohort study was conducted on patients who underwent PCLR with the Al-PCLR technique and CON-PCLR technique from 2012 to 2023 in a single hospital. Medical records were reviewed for patients' demographic data, the technique of PCL reconstruction and complications. Patient-reported outcome scores, including International Knee Documentation Committee (IKDC), Tegner activity scale, and Lysholm score, as well as bilateral kneeling radiographs and physical examinations, were collected at least 2 years postoperatively. Results: Included in the study were 24 patients: 11 who underwent the CON-PCLR technique (mean age 40.7 +years) and 13 who underwent Al-PCLR (mean age 34.3 + 12.9 years). Three patients in AI-PCLR group were lost to follow-up and one patient is the CON-PCLR group, a revision case, was excluded from the study.Bilateral stress kneeling radiographs showed a similar side-to-side difference between two groups (CON-PCLR vs AL-PCLR: mean 7.5 ± 5.2 vs 5.8 ± 4.8 mm; P = 0.38) There were no statically significant differences between the two groups in postoperative IKDC (CON-PCLR vs AL-PCLR: 68.9 vs 73.9; P = 0.37), Lysholm (89.1 vs 94.1; P = 0.42), or Tegner activity (6 vs 6.4; P = 0.68) scores. Conclusion: All-inside PCLR demonstrates comparable stability to Conventional PCLR, with satisfactory patient-report outcome at minimum 2 years follow up and low rate of complications in patients with multiligament knee injury.Level of evidence: III Retrospective comparative study.

RESUMEN

PURPOSE: To compare the clinical outcomes between arthroscopic partial rotator cuff repair with biceps augmentation (BA) and partial repair (PR) without BA. METHODS: This systematic review included studies comparing outcomes of arthroscopic repair for large to massive irreparable rotator cuff tears with and without the BA. The focus was on postoperative clinical results and retear rates. Mean differences were used to express continuous outcomes, while odds ratios (ORs) were employed for dichotomous outcomes. RESULTS: Ten studies (733 shoulders, all level 3 evidence) were included. The BA group showed a significant reduction in retear rates (OR = 0.40, 95% confidence interval [CI]: 0.20-0.77, P = 0.007) and comparable postoperative outcomes across various measures: American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale for pain, University of California-Los Angeles shoulder score, active forward flexion motion and active external rotation at the arm-at-side position compared to the PR group. Subgroup analysis of two BA techniques-rerouting and supplementation following supraglenoid tenotomy-showed no significant differences in ASES score for either technique versus PR. However, rerouting significantly lowered retear rates (OR = 0.21, 95% CI: 0.12-0.36, p < 0.001), while supplementation showed similar retear rates to PR (OR = 0.87, 95% CI: 0.37-2.02, n.s.). CONCLUSION: Arthroscopic partial rotator cuff repair with BA for large to massive irreparable rotator cuff tears is a reliable technique, resulting in improved postoperative outcomes. BA using supplementation following supraglenoid tenotomy showed similar clinical outcomes and range of motion but with lower retear rates compared to the PR group. LEVEL OF EVIDENCE: Level III.

RESUMEN

PURPOSE: To characterize the risk of revision hip arthroscopy or conversion to total hip arthroplasty (THA) among patients with a history of lumbar fusion undergoing primary hip arthroscopy. METHODS: We used the Statewide Planning and Research Cooperative System, an administrative database including all ambulatory and inpatient surgery encounters in New York (NY), to identify all patients who underwent hip arthroscopy for FAI between 2010-2020. Patients with prior lumbar fusion were identified using CPT and ICD 9th/10th Revision coding definitions. Patients with and without prior fusion were matched in a 1:5 ratio according to age and comorbidity burden. The number of levels fused was defined in the following fashion: i) no fusion, ii) 1-2 levels, or iii) ≥3 levels. Patients were followed for two years to evaluate the rate of revision hip arthroscopy or conversion to THA. Multivariable logistic regression models were used to measure the association between number of levels fused and revision hip arthroscopy or conversion to THA. RESULTS: Between 2010-2020, there were 23,277 patients that underwent primary hip arthroscopy in NY state. Of these, 348 (1.4%) had a prior lumbar fusion. After matching for age and comorbidities, the composite rate of revision hip arthroscopy or conversion to THA was higher in patients with prior lumbar fusion compared to patients without (16.5% vs. 8.5%; P < 0.001). This risk increased with the number of levels fused (1-2 levels: 15.1%; aOR, 1.8; 95% CI, 1.3-2.6; vs. ≥3 levels: 26.3%; aOR, 3.4; 95% CI, 1.7-7.0). CONCLUSION: Patients with a history of lumbar fusion had significantly higher rates of revision hip arthroscopy and conversion to THA compared to patients without prior fusion. The risk of revision hip arthroscopy or conversion to THA was increased approximately 2-fold in patients with 1-2 levels fused and 3-fold in patients with 3 or more levels fused. LEVEL OF EVIDENCE: Level III, prognostic retrospective matched comparative case series.

RESUMEN

In lateral patellar dislocation, injuries commonly involve the medial retinaculum and the medial patellofemoral ligament (MPFL). Stabilizing the medial soft tissue is crucial, with options including MPFL repair, reconstruction, or medial retinacular plication. For acute cases, MPFL reconstruction may be overly invasive, leading to donor site morbidity and scarring concerns, especially in young females. The authors propose an arthroscopic-assisted medial retinacular plication technique through stab wounds for acute dislocations, offering the advantage of being less invasive with good cosmetic outcomes.

RESUMEN

Background: The hamstring autograft can be harvested using various skin incisions, such as vertical, transverse, and oblique incisions, and from different localizations, including anteromedial and posteromedial harvest sites. The aim of this study was to compare studies on the anteromedial and posteromedial approaches for hamstring autograft harvest in terms of clinical outcomes, saphenous nerve injury, infection, operative time, graft length, incision length, range of motion, and patient satisfaction. Methods: Following the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines, a search was conducted in PubMed and Scopus, focusing on studies comparing anteromedial and posterior approaches for hamstring harvest. This study was registered with the PROSPERO International Prospective Register of Systematic Reviews (CRD42023450249). Methodological quality was evaluated using the Modified Coleman Methodology Score. Odds ratios (ORs) and mean differences (MDs) quantified dichotomous and continuous outcomes, respectively. Results: Five articles, involving 405 knees, underwent analysis. Four studies were level 3 evidence, while 1 was level 1. The anteromedial hamstring harvest showed higher rates of saphenous nerve injury (OR, 9.77; 95% confidence interval [CI], 2.19-43.65; p = 0.003) and longer operative times, with an MD of about 13 minutes (MD, 13.33; 95% CI, 0.68-25.97; p = 0.04), compared to the posteromedial approach. The anteromedial method yielded a longer semitendinosus graft, with an MD of about 17 mm (MD, 17.57; 95% CI, 7.17-27.98; p = 0.0009). However, no significant differences existed in range of motion, flexion contracture, unintentional graft harvest, infection rates, and patient-reported outcomes. Notably, the posteromedial group reported higher cosmetic satisfaction, with 92% being very satisfied, compared to the anteromedial group with 80% (p = 0.005). However, overall satisfaction levels were similar between the 2 groups (p = 0.35), with a very satisfied rate of 72% for the anteromedial group and 78% for the posteromedial group. Conclusions: The anteromedial hamstring harvest showed greater saphenous nerve injury and longer operative times compared to the posteromedial approach, along with a longer graft. However, no significant differences were observed in the range of motion, flexion contracture, graft harvest, infection, or patient outcomes.

RESUMEN

Shoulder instability, often associated with both soft tissue and bone lesions, can result in shoulder pain and dysfunction. To address this, the combined procedure of a Bankart repair in conjunction with humeral avulsion of the glenohumeral ligament (HAGL) repair aims to minimize failure rates in a single procedure. While HAGL repair is imperative for preventing recurrent instability, there remains a lack of consensus on the optimal surgical technique. This Technical Note aims to elucidate a surgical approach for addressing and repairing HAGL lesions using arthroscopy, specifically employing a combined posterior viewing portal and posteroinferior working portal in the beach-chair position.

RESUMEN

INTRODUCTION: The optimal arthroscopic management for popliteal cyst decompression remains uncertain, with ongoing debate between preserving the cyst wall or completely removing it. The purpose of this study is to compare the outcomes and complications of arthroscopic popliteal cyst decompression with cyst wall preservation and cyst wall resection. METHODS: A systematic review adhering to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines was conducted. It encompassed studies that focused on arthroscopic popliteal cyst decompression, considering both cyst wall preservation and cyst wall resection. The quality assessment of the included studies was carried out using the Methodology Index for Non-Randomized Research criteria. Following this, meta-analyses were conducted, employing odds ratios (ORs) for dichotomous outcomes and calculating mean differences (MDs) for continuous outcomes. RESULTS: Four articles included a collective of 214 knees. Each of these studies presented level 3 evidence. The comparison between the cyst wall preservation group and the cyst wall resection group revealed similar clinical outcomes based on the Rauschning and Lindgren grade (grade 0 [OR = 0.66, 95% CI: 0.37-1.19, p = 0.17]; grade I [OR = 1.33, 95% CI: 0.66-2.67, p = 0.43]; grade II [OR = 1.39, 95% CI: 0.46-4.14, p = 0.56]; grade III [OR = 3.46, 95% CI: 0.13-89.95, p = 0.46]) and Lysholm score (MD = 0.83, 95% CI: -0.65-2.32, p = 0.27). However, MRI results indicated a significant improvement in the cyst wall resection group (cyst disappearance [OR = 0.50, 95% CI: 0.28-0.90, p = 0.02]; cyst shrinkage or decrease in size [OR = 1.41, 95% CI: 0.78-2.55, p = 0.26]; cyst persistence or recurrence [OR = 7.63, 95% CI: 1.29-45.08, p = 0.02]). Nevertheless, the operative time for cyst resection was significantly longer compared to cyst preservation (MD = -14.90, 95% CI: -21.96 - -7.84, p < 0.0001), and the cyst wall resection group experienced significantly higher complications than the cyst wall preservation group (OR = 0.24, 95% CI: 0.06 to 1.02, p = 0.05). CONCLUSION: During arthroscopic popliteal cyst decompression, cyst wall resection led to longer operative times and higher complication rates but lower recurrence rates and better MRI outcomes. The functional outcomes after surgery were found to be similar.

RESUMEN

Posterolateral tenodesis is necessary for restoring biomechanics in posterolateral instability of the knee. We propose a technique that provides the tenodesis effect to both intra- and extra-articular aspects of the knee. We call it the posterolateral intra-/extra-articular tenodesis technique, which is a technique for posterolateral reconstruction. This minimally invasive technique is particularly helpful in patients with high-grade posterolateral corner injury with the advantage of precise placement of the graft.

RESUMEN

OBJECTIVE: To determine the mean contact pressure, peak contact pressure, and mean contact area of the lateral tibiofemoral joint in lateral extra-articular tenodesis (LET) with tension on the graft in tibial neutral and external rotation. METHODS: A total of eight Thiel-embalmed cadaveric knees were prepared and divided into two groups (4 knees in each group): the LET-NR group (lateral extra-articular tenodesis tension in neutral rotation) and (2) the LET-ER group (lateral extra-articular tenodesis tension in external rotation). Each knee was prepared according to the corresponding technique. A hydraulic testing system (E10000, Instron) simulates an axial load of 735 â€‹N for 10 â€‹s in each group. RESULTS: The LET-ER group exhibited a statistically significant higher peak contact pressure compared to the LET-NR group. The peak contact pressure values in the LET-NR and LET-ER groups were 702.3 â€‹± â€‹233.9 â€‹kPa and 1235.5 â€‹± â€‹171.4 â€‹kPa, respectively (p â€‹= â€‹0.010, 95% CI, -888.0 to -178.5). The mean contact pressure values in the LET-NR and LET-ER groups were 344.9 â€‹± â€‹69.0 â€‹kPa and 355.3 â€‹± â€‹34.9 â€‹kPa, respectively (p â€‹= â€‹0.796, 95% CI, -105.1-84.2). The mean contact area values in the LET-NR and LET-ER groups were 36.8 â€‹± â€‹3.1 mm2 and 33.3 â€‹± â€‹6.4 mm2, respectively (p â€‹= â€‹0.360, 95% CI, -5.2-12.2). CONCLUSIONS: The peak contact pressure of the lateral tibiofemoral joint is greater in LET when the graft is tensioned in external rotation than in neutral rotation. However, no statistically significant difference in the mean contact pressure or the mean contact area was observed between the two groups. LEVEL OF EVIDENCE: III.

RESUMEN

PURPOSE: To determine the effect of hip external rotation or extension/adduction on minimizing the ischiofemoral distance (IFD) and assess the correlation between cadaveric and fluoroscopic IFD measurements in different hip positions. METHODS: This cadaveric study involved 33 hip joints from 17 embalmed cadavers. IFD, the distance between the lesser trochanter and lateral ischium, was measured in different hip positions: neutral, external rotation at 30°, and external rotation at 60° with the hip in both neutral extension and adduction as well as 10° hip extension and 10° hip adduction. Differences in IFD related to positions and correlation between cadaveric and fluoroscopic measurements were analyzed. RESULTS: IFD measurements showed that the greatest reduction occurred at 60° of external hip rotation, with a significant difference observed only between neutral and 60° external rotation in cadaveric groups (7.60 ± 4.68 vs 5.05 ± 3.48, 95% CI, 0.14-4.96; P = .036). No substantial difference was observed between the extension and adduction positions. Positive correlations were observed between cadaveric and fluoroscopic measurements, especially in the neutral position (r = 0.492, P = .004), external rotation at 30° (r = 0.52, P = .002), external rotation at 60° (r = 0.419, P = .015), and the extension/adduction positions combined with neutral rotation (r = 0.396, P = .023). CONCLUSIONS: The IFD significantly decreased with increasing degrees of hip external rotation, particularly at 60°. No significant reduction was observed in the extension/adduction positions. In addition, positive correlations were observed between cadaveric and fluoroscopic measurements for specific hip positions: neutral rotation, external rotation at 30° and 60°, and extension/adduction at 10° with neutral rotation. CLINICAL RELEVANCE: Surgeons can use this knowledge to improve hip impingement assessment through radiography, focusing on positions in which IFD reduction is most notable. Understanding the relationship between hip positions and IFD can enhance the diagnosis of ischiofemoral impingement syndrome and benefit patient care and outcomes.

RESUMEN

After a lateral patellar dislocation or subluxation, injury to the medial patellofemoral ligament (MPFL) is common. The MPFL originates between the medial epicondyle and the adductor tubercle, inserting along the superior one-third border of the medial patella. Operative treatment becomes necessary for patients with intra-articular pathology (such as osteochondral injuries or meniscus tears) or those experiencing recurrent dislocations. Numerous surgical techniques have been proposed for addressing this issue, with MPFL reconstruction being the most frequently performed procedure. Nonetheless, various complications associated with reconstruction have been documented. In recent years, there has been a growing interest in MPFL repair, which has shown acceptable outcomes in the literature. In this study, we introduce an arthroscopic-assisted MPFL repair technique designed for acute traumatic MPFL tears originating from the patellar insertion. This approach offers the advantage of being minimally invasive, straightforward, and reproducible.

RESUMEN

Arthroscopic anterior cruciate ligament reconstruction is a common procedure that requires effective postoperative pain management for successful rehabilitation. Opioids are traditionally used for pain relief, but their side effects decrease their widespread use. Local anesthesia techniques have gained interest as an alternative to opioids. This Technical Note discusses the use of an anesthetic cocktail for pain relief at the hamstring's donor site in anterior cruciate ligament reconstruction. This approach may enhance early rehabilitation and patient satisfaction.

RESUMEN

The Bankart lesion is a common injury to the labrum in the shoulder joint, usually resulting from anterior shoulder dislocation. Arthroscopic Bankart repair is a surgical technique used to treat recurrent dislocations by reattaching the labrum to the glenoid rim using suture anchors. Typically, 3 portals are created: 1 for visualization and 2 for instrumentation. However, this Technical Note proposes a single working portal approach using a 70° arthroscope from the posterior portal. This technique enhances visualization and prevents portal jamming, particularly in cases with a small rotator interval.

RESUMEN

Background/objective: During the initial stages of rehabilitation after anterior cruciate ligament (ACL) surgery, a pivotal role is played in ensuring effective recuperation and averting complications. An often-employed strategy to tackle ACL laxity during this period involves the incorporation of synthetic materials for reinforcement. The objective of this study is to compare the effectiveness of conventional suture tape and multiple high-strength sutures as augmentation techniques for ACL repair. Methods: Ten preserved cadaveric knees embalmed using the Thiel method were segregated into two groups, each containing five knees. In one group, traditional suture tape was employed for augmentation, while the other group utilized multiple high-strength sutures. Each knee underwent a cyclic load of 1000 sine wave cycles, succeeded by an axial distraction load until failure ensued. The resultant displacement and ultimate load at failure were assessed to contrast the efficacy of the two augmentation techniques. Results: The group utilizing multiple high-strength sutures exhibited a significantly higher load to failure at time-zero (1690.7 N) compared to the suture tape group (987.6 N) (P = .003). Furthermore, the multiple high-strength sutures group demonstrated significantly reduced displacement after 1000 cyclic loads (6.6 mm) in comparison to the suture tape group (16.3 mm) (P < .001). Conclusions: Multiple high-strength sutures show better biomechanical properties for the augmentation of ACL repair at time-zero. Both suture tape and multiple high-strength sutures had ultimate load-to-failure values higher than the natural ACL loads. Therefore, these substances might serve as augmentation options to prevent the ACL's gradual elongation, a critical concern particularly in the initial stages of rehabilitation.

RESUMEN

BACKGROUND: Bone marrow stimulation (BMS) techniques such as microfracture, nanofracture, and the crimson duvet procedure expose the bone marrow of the proximal humerus to the rotator cuff tendon footprint. The effect of performing BMS on tendon healing is a subject of interest. PURPOSE: To compare studies on arthroscopic rotator cuff repair with BMS versus without BMS for rotator cuff tears according to healing rates and clinical and radiological outcomes. STUDY DESIGN: Systematic review and meta-analysis; Level of evidence, 2. METHODS: The 2020 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed in conducting a search. Studies that compared arthroscopic rotator cuff repair with and without BMS were included if they provided postoperative patient-reported outcomes and healing rates. Dichotomous outcomes were expressed as mean differences (MDs), while continuous outcomes were expressed as odds ratio. RESULTS: Included were 5 studies (N = 499 shoulders); 4 studies had level 1 evidence, and 1 study had level 2 evidence. The healing rate of rotator cuff repair was similar between the 2 groups (ie, with and without BMS) (odds ratio, 1.58 [95% CI, 0.63 to 4.00]; P = .33). Furthermore, there were no significant differences in the postoperative Constant score (MD, 1.41 [95% CI, -0.58 to 3.39]; P = .16), American Shoulder and Elbow Surgeons score (MD, 0.77 [95% CI, -1.43 to 2.96]; P = .49), or range of motion for forward flexion (MD, 2.45 [95% CI, -0.66 to 5.57]; P = .12) and external rotation (MD, 0.81 [95% CI, -2.35 to 3.97]; P = .62) at the final follow-up between the 2 groups. CONCLUSION: The healing rate of rotator cuff repair was similar, regardless of whether BMS was performed or not. Additionally, there was no significant difference in postoperative patient-reported outcome scores, range of motion, and complications. REGISTRATION: CRD42023388427 (PROSPERO).

RESUMEN

Background: The Latarjet procedure is a common procedure for treating critical glenoid bone loss in anterior shoulder instability. Implants such as the screw and cortical button are widely used. The aim of this study was to compare studies on screw versus button fixation techniques in the Bristow-Latarjet procedure for anterior shoulder instability in terms of clinical outcomes, union rates, and complications. Methods: The PubMed, Scopus, and Embase databases were searched to find comparative studies that reported outcomes of using screw versus button fixation in the Bristow-Latarjet procedure following the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Studies that directly compared the screw and button fixation techniques and provided postoperative patient-reported outcomes, union rates, or complications were included. The Methodology Index for Non-Randomized Research (MINORS) criteria were used to assess the quality of the included studies. Odds ratios (ORs) were calculated for dichotomous outcomes whereas mean differences were calculated for continuous outcomes. Results: Five articles included a total of 877 shoulders. All five studies had level 3 evidence. There was no statistically significant difference between the two techniques using the Walch-Duplay score, visual analog scale for pain, American Shoulder and Elbow Surgeons score, Simple Shoulder Test, range of motion, and graft union rates. However, the button fixation technique had statistically significantly higher recurrence rates than the screw fixation technique (OR, 0.24; 95% confidence interval, 0.10-0.58; p = 0.001). Conclusions: The screw fixation technique had statistically significantly lower recurrence rates than the button fixation technique. However, there was no significant difference between screw and button fixation techniques regarding postoperative patient-reported outcomes, range of motion, graft union rates, nerve injury rates, infection rates, and reoperation rates.

RESUMEN

Background: While increased posterior tibial slope (PTS) is an important risk factor for failure after anterior cruciate ligament (ACL) reconstruction, controversy exists regarding indications and outcomes of proximal tibia anterior closing-wedge osteotomy (ACWO) with concomitant ACL reconstruction in patients with ACL tears. Purpose: To assess clinical outcomes after combined ACL reconstruction and proximal tibia ACWO. Study Design: Systematic review; Level of evidence, 4. Methods: In accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines, we performed a systematic review of the existing literature on ACWO and ACL reconstruction using PubMed (MEDLINE), Cochrane Library, Scopus, and Embase. The search phrases included "anterior closing wedge osteotomy,""anterior closing wedge tibial osteotomy,""anterior closing wedge proximal tibial osteotomy,""anterior cruciate ligament," and "revision anterior cruciate ligament." Non-English publications and single-patient case reports were excluded. Extracted data included study details, patient demographics, patient-reported outcomes (PROs), clinical outcomes, radiographic outcomes, complications, and return-to-sport (RTS) rates. Results: A total of 6 studies with 110 patients (110 knees) were included. Two-stage ACWO and ACL reconstruction was reported in 2 studies of 78 patients (71%), while a single-stage technique was reported in 4 studies of 32 patients (29%). ACWO was performed in the setting of primary ACL tear in 23 patients (21%) and in recurrent ACL tear in 87 patients (79%). Patients demonstrated postoperative improvements in Lysholm, pivot-shift test, and side-to-side difference in anterior tibial translation. After ACWO, all studies reported mean postoperative PTS of <10° (range, 4.4°-9.2°). Of patients with available RTS data (n = 43), the same-level RTS rate ranged from 65% to 100%. A two-stage procedure reported in 1 study had a lower RTS rate (n = 13 of 20 [65%]) than that of 2 studies with single-stage procedure (n = 4 of 5 [80%] and n = 18 of 18 [100%]). The overall complication rate was 0.9% to 1.3%, and there were no reported ACL retears. Conclusion: The current evidence, which is constrained by the quantity and quality of studies, showed that ACWO with single- or two-stage ACL reconstruction in patients with ACL insufficiency and increased PTS was associated with significant improvements in PROs and high RTS rates.

RESUMEN

An anterior cruciate ligament (ACL) tear is one of the most common ligament injuries in athletes. The arthroscopic ACL reconstruction procedure is the gold standard for treatment. However, the improvement in injury classification and suture materials has subsequently made arthroscopic ACL primary repair an alternative surgical treatment option. This Technical Note describes an arthroscopic ACL primary repair with synthetic augmentation made of several high-strength sutures and fixation with the knotless suture anchor. The reinforced synthetic material acts as a structural tie to support the ACL while it heals.

RESUMEN

PURPOSE: This study aimed to review studies comparing transtendon repair (TTR) with tear completion repair (TCR) techniques for partial articular-sided supraspinatus tendon avulsion (PASTA) lesions according to postoperative patient-reported outcomes and complications. METHODS: Databases, including PubMed, Embase, Scopus, and Cochrane, were searched for studies published between 2008 and 2022 that directly compared the postoperative patient-reported outcomes and complications of the TTR and TCR techniques for PASTA lesions. Odds ratios (ORs) were calculated for dichotomous outcomes, while mean differences (MDs) were calculated for continuous outcomes. RESULTS: A total of seven studies (497 shoulders) were analysed. No statistically significant differences in the postoperative clinical outcomes at the final follow-up were observed between the TTR and TCR techniques for PASTA lesions. The overall retear rates of the TTR and TCR techniques were 7.7% and 11.6%, respectively (corresponding healing rates were 92.3% and 88.4%), whereas the overall occurrence rates of adhesive capsulitis were 4.7% and 3.3%, respectively. Furthermore, no significant difference was observed in postoperative range of motion (forward flexion, MD = - 1.22, 95% confidence interval (95%CI) - 5.28 to 3.34, n.s.; external rotation, MD = - 1.39, 95% CI - 3.19 to 0.42, n.s.), overall retear rate (OR 0.72, 95% CI 0.29-1.08, n.s.), and occurrence rate of adhesive capsulitis (OR 1.11, 95% CI 0.35-3.52, n.s.) between the two techniques. CONCLUSION: Both techniques improve clinical outcomes while having a low complication rate and a high rate of healing. No significant difference in clinical outcomes was observed between the two techniques. LEVEL OF EVIDENCE: III.

RESUMEN

The critical consideration in determining the efficacy of hip surgery is patient-reported outcomes, specifically the achievement of the clinical threshold. Several studies examined the achievement of the clinical threshold following hip arthroscopy (HA) in the presence of coexisting lumbar spine disease. The condition related to the spine receiving a lot of focus in recent research is the lumbosacral transitional vertebrae (LSTV). However, this condition could be just the tip of the iceberg. To forecast the outcomes of HA, it is far more important to comprehend spinopelvic motion. Since higher-grade LSTV is associated with less lumbar spine flexibility and reduces the ability to antevert acetabulum, it is possible that LSTV severity or grading could be one of the indicators of less effective operation "especially in "hip users"' (hip users are defined as patents who are more dependent on on hip motion than spinal motion). In light of this, lower-grade LSTV ought to have a less significant impact on surgical outcomes than higher-grade LSTV.
