Meta-Analysis Review
Could anterior closed-wedge high tibial osteotomy be a viable option in patients with high posterior tibial slope who undergo anterior cruciate ligament reconstruction? A systematic review and meta-analysis.
PURPOSE
This study aims to examine the clinical and radiological outcomes of patients who underwent ACL reconstruction (ACLR) combined with anterior closed-wedge high tibial osteotomy (ACW-HTO) for posterior tibial slope (PTS) reduction to investigate the efficacy of this procedure in improving anterior knee stability and preventing graft failure in primary and revision ACLR.
METHODS
A literature search was conducted in six databases (PubMed, Embase, Medline, Web of Science, Cochrane, and Scopus). The study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The initial screening identified 1246 studies. Each eligible clinical article was screened according to the Oxford Centre for Evidence-Based Medicine 2011 levels of evidence (LoE), excluding clinical studies of LoE V. Quality assessment of the articles was performed using the ROBINS-I methodological evaluation. This systematic review and meta-analysis was registered on the International Prospective Register of Systematic Reviews (PROSPERO). For the outcomes that were possible to perform a meta-analysis, a p < 0.05 was considered statistically significant.
RESULTS
Five clinical studies were included in the final analysis. A total of 110 patients were examined. Pre- and post-operative clinical and objective tests that assess anteroposterior knee stability, PTS, clinical scores, and data on surgical characteristics, complications, return to sports activity, and graft failure after ACLR were investigated. A meta-analysis was conducted using R software, version 4.1.3 (2022, R Core Team), for Lysholm score and PTS outcomes. A statistically significant improvement for both these clinical and radiological outcomes (p < 0.05) after the ACW-HTO surgical procedure was found.
CONCLUSION
ACLR combined with ACW-HTO restores knee stability and function with satisfactory clinical and radiological outcomes in patients with an anterior cruciate ligament injury associated with a high PTS and seems to have a protective effect from further ruptures on the reconstructed ACL.

Meta-Analysis
BACKGROUND
Injury to the ulnar collateral ligament of the elbow is common among overhead throwing athletes and can result in significant functional limitations. While surgical reconstruction offers high rates of return to competition, there are no validated or universally accepted guidelines for determining when an athlete can safely resume play.
PURPOSE
To assess the existing scientific literature for return-to-competition criteria utilized after ulnar collateral ligament reconstruction.
STUDY DESIGN
Systematic review and meta-analysis; Level of evidence, 4.
METHODS
The PubMed database was searched for clinical investigations of ulnar collateral ligament reconstruction in overhead throwing athletes published between January 2000 and June 2020. Only studies that had a minimum follow-up of 1 year and included at least 1 specific return-to-competition criterion were considered.
RESULTS
A total of 15 studies were included in the final analysis, encompassing 1156 patients with an average age of 20.7 years (SD, 2.0 years). Baseball players composed 96.3% of patients for whom sport was specified, and 92.4% of baseball players were pitchers. The most common return-to-competition criterion, identified in 87% of studies, was completion of a return-to-throwing program, which started on average 16.7 weeks (range, 12-18 weeks) after surgery. A return-to-mound program was utilized in 53% of studies, starting on average 7.4 months (range, 6-9 months) postoperatively. Minimum time from surgery was used in 73% studies, with players waiting 7 to 12 months (mean, 9.7; SD, 1.4 months) after surgery before return-to-competition consideration. The overall rate of return to competition at the preinjury level or higher was 85.7% (SD, 8.5%) at an average of 12.2 months (SD, 0.6 months).
CONCLUSION
In general, we observed a paucity of literature describing the return-to-competition process after ulnar collateral ligament reconstruction in overhead throwing athletes. Only 3 explicit return-to-competition criteria were identified across all studies: completion of a return-to-throwing program, completion of a return-to-mound program for pitchers, and minimum time from surgery. Increased transparency regarding postoperative rehabilitation protocols and further research are necessary to identify and validate sport-specific return-to-competition criteria, which will ultimately help athletes return to play in a safe and timely fashion after ulnar collateral ligament reconstruction.

Meta-Analysis
Combined Lateral Extra-Articular Tenodesis or Combined Anterolateral Ligament Reconstruction and Anterior Cruciate Ligament Reconstruction Improves Outcomes Compared to Isolated Reconstruction for Anterior Cruciate Ligament Tear: A Network Meta-analysis of Randomized Controlled Trials.
PURPOSE
To conduct a network meta-analysis (NMA) comparing the results of randomized controlled trials (RCTs) among patients who underwent either isolated anterior cruciate ligament (ACL) reconstruction or combined lateral extra-articular tenodesis (LET) or anterolateral ligament reconstruction (ALLR).
METHODS
RCTs that compared isolated ACL reconstruction and combined LET or ALLR were included with minimum 12 months follow-up. Studies that used the double-bundle technique were excluded. Outcome assessment included the number of positive pivot shifts, amount of anterior tibial translation, and International Knee Documentation Committee (IKDC) subjective, Tegner, and Lysholm scores. Bayesian NMA and the surface under the cumulative ranking area (SUCRA) were evaluated.
RESULTS
A total of 1,077 patients from 11 RCTs were enrolled in this study. In NMA, the odds ratios (ORs) of positive pivot shift were significantly lower in ACL + ALLR (OR: 0.17; 95% CI: 0.027-0.67) than isolated ACL reconstruction, but no difference between ACL + ALLR and ACL + LET. There were no significant differences in anterior tibial translation among the techniques, but the IKDC subjective and Lysholm scores of ACL + ALLR and ACL + LET were significantly higher than isolated ACL reconstruction. ACL + ALLR were the most preferred in terms of residual pivot shift, anterior tibial translation, and IKDC subjective scores (SUCRA = 88.2%, 86.4%, and 93.1%, respectively). Additional lateral procedures resulted in significantly lower risk of graft failure (OR: 0.27; 95% CI: 0.1-0.71) than isolated ACL reconstruction.
CONCLUSIONS
ACL + ALLR were found to have significantly better outcomes in terms of knee rotational stability and graft failure rate than isolated ACL reconstructions, but the clinical outcomes were uncertain after a minimum 12 months follow-up. Considering the greatest probability of obtaining better knee rotational stability in this NMA, ACL + ALLR was found to be the most preferred technique for patients with ACL injury.

Review
Posterior olecranon fracture dislocations (POFDs) were considered posterior Monteggia lesions, which were less described in the literature. The purpose of this study was to provide a systematic review of the diagnosis, treatment, prognosis, and complications of POFDs in adults. A systematic review was performed to identify all relevant studies on the POFDs in the PubMed, Web of Science, Embase, and MEDLINE databases. The methodological quality of the studies was scored using the Methodological Index for Non-Randomized Studies (MINORS). A total of 117 patients were identified in the nine studies selected. The high-energy injuries accounted for 42.7% of the included studies. The rates of concomitant coronoid process, radial head fractures, and lateral collateral ligament injury were 84.6% (99/117), 87.2% (102/117), and 5% (6/117), respectively. The procedure was performed with a dorsal mid longitudinal approach to reconstruct all injury components. The postoperative clinical scores included the Broberg/Morrey rating, with a mean rating of excellent or good at 66%, the mean DASH score was 20.6, and the mean ASES score was 83. The flexion and extension arc and forearm rotation arcs were 100° and 134°, respectively. Complications included arthrosis in 28.2% (33/117) of cases, fracture nonunion or delayed union in 9.4% (11/117) of cases, heterotopic ossification in 7% (8/117) of cases, and the re-operation rate was 16% (19/117). There was nearly no postoperative ulnohumeral instability. The main characteristics of POFDs were disruptions of the trochlear notch, including the olecranon and coronoid processes, and severe radial head fractures, while the lateral collateral ligament was spared. Although the POFDs had a low frequency of instability, the prognosis was relatively poor. The POFDs should be considered independently.

Meta-Analysis Review
BACKGROUND
The aim of anterior cruciate ligament reconstruction (ACLR) is to restore the function of the knee joint, protect the cartilage, and reduce the occurrence of osteoarthritis. However, due to the structural limitations of the human body, it is not possible to perform ACLR with conventional sutures. To restore normal functioning of the anterior cruciate ligament (ACL), a new ligament must be reconstructed in the position of the previous ACL.
OBJECTIVE
To compare autografts and synthetic grafts in terms of postoperative knee stability and function SEARCH METHODS: The protocol for this study was registered with PROSPERO (CRD42021243451). Two reviewers independently searched the PubMed, Embase, and the Cochrane Library databases from database inception though February 10, 2021. The following search method was used: ((Autograft) OR (Autologous) OR (Autotransplant)) OR Artificial Ligament AND (Anterior Cruciate Ligament Injury [MeSH Terms]) AND (Randomized controlled trial [MeSH Terms]). Methodological quality was assessed by the Cochrane risk of bias tool.
SELECTION CRITERIA
We only included randomized controlled trials (level I) that compared autograft and synthetic graft interventions in participants with ACL injury. We included trials that evaluated ACLR using at least one outcome (Lachman test, pivot shift test, IKDC grades, or complications).
RESULTS
A total of 748 studies were identified in the initial literature search, and seven studies that examined only bone-patellar tendon-bone (BPTB) grafts compared with artificial grafts met the predetermined inclusion criteria. The results showed that BPTB grafts were associated with significantly better pivot shift test and Lachman test results and better IKDC grades and lower complication rates than synthetic grafts.
CONCLUSIONS
This review indicates that for adults, BPTB grafts perform more favorably than synthetic grafts in ACLR in terms of knee stability, function, and complication. More research is needed to compare autologous tendons and allogeneic tendons with artificial ligaments, especially in elderly individuals.

Meta-Analysis
The Role of Anterolateral Ligament Reconstruction or Lateral Extra-articular Tenodesis for Revision Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-analysis of Comparative Clinical Studies.
BACKGROUND
After its success in restoring rotational stability and reducing failure rates in primary anterior cruciate ligament reconstruction (ACLR), lateral extra-articular tenodesis (LET) or anterolateral ligament reconstruction (ALLR) has been endorsed for use in revision ACLR surgery, where failure rates are historically higher.
PURPOSE
To perform a systematic review and meta-analysis on whether the addition of a LET or ALLR results in superior clinical outcomes and stability compared with isolated revision ACLR (iACLR).
STUDY DESIGN
Meta-analysis; Level of evidence, 4.
METHODS
The Cochrane Controlled Register of Trials, PubMed, Medline, and Embase were used to perform a systematic review and meta-analysis of comparative studies using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria with the following search terms: ("extra-articular" OR "tenodesis" OR "anterolateral ligament" OR "iliotibial") AND ("anterior cruciate ligament") AND ("revision" OR "re-operation"). Data pertaining to all patient-reported outcome measures (PROMs), rotational stability, and postoperative complications were extracted from each study.
RESULTS
After abstract and full-text screening, 10 clinical comparative studies were included. There were 793 patients, of whom 390 had an iACLR while 403 had an ACLR augmented with a LET or an ALLR (augmented ACLR [aACLR]). The mean time for assessment of PROMs was 35 months. The aACLR group had superior International Knee Documentation Committee (IKDC) scores (standardized mean difference [SMD], 0.27; 95% CI, 0.01 to 0.54; = .04), rotational stability (odds ratio [OR], 2.77; 95% CI, 1.91 to 4.01; < .00001), and lower side-to-side difference (OR, -0.53; 95% CI, -0.81 to -0.24; = .0003) than those without the augmentation. Furthermore, they were less likely to fail (OR, 0.44; 95% CI, 0.24 to 0.80; = .007). Subgroup analysis in the higher-grade laxity cohort (grade ≥2) revealed an even greater IKDC score (SMD, 0.51; 95% CI, 0.16 to 0.86; = .005) and an improved Lysholm score (SMD, 0.45; 95% CI, 0.24 to 0.67; < .0001) in the aACLR group.
CONCLUSION
Revision aACLR with a LET or an ALLR can improve subjective IKDC scores, restore rotational stability, and reduce failure rates compared with iACLR. Although controversy remains on the necessity of augmenting all revision ACLRs, the present meta-analysis advocates adding a lateral procedure, particularly in those with a higher-grade pivot shift.

BACKGROUND
Rates of return to physical activity after anterior cruciate ligament reconstruction surgery are sub-optimal. Optimising presurgical treatment may improve return rates. The purpose of this systematic review was to identify modifiable preoperative predictors for return to physical activity after anterior cruciate ligament reconstruction.
METHODS
Seven electronic databases (CINAHL, MEDLINE and SPORTDiscus via EBSCOhost, AMED, PsycINFO and EMBASE via OVID and Web of Science) were searched from inception to 31 March 2023. The population of focus was adults aged 18-65 who had undergone primary anterior cruciate ligament reconstruction. Studies needed to identify at least one potential modifiable preoperative predictor variable and the relationship between the predictor(s) and return to physical activity. All time-points of assessment and study designs were included. Data extraction was completed by one reviewer and verified by a second reviewer. Two reviewers completed the risk of bias assessment using the Quality in Prognostic Studies tool and Grading of Recommendations Assessment, Development and Evaluation system.
RESULTS
The search identified 2281 studies, eight met the inclusion criteria. Five studies scored 'high', and three studies scored 'moderate' risk-of-bias. All preoperative predictors were of very low-quality evidence. Five different outcome measures were used to assess return to physical activity including Tegner, Marx, Physical Activity Scale, return to play at the elite level and return to preinjury level (undefined). This was measured between 1- and 10-years post-surgery. Nine preoperative physical, six psychosocial and five demographic/clinical factors were assessed and four were found to be predictive. These included quadriceps strength, psychological profile, patient estimated ability to return and graft type (patella tendon, BPTB).
CONCLUSION
Very-low level evidence suggests that increasing quadriceps strength, managing patient expectations of their treatment outcomes, improving motivation to resume preinjury activity levels and considering the use of a BPTB graft will support return to physical activity after ACLR.

Meta-Analysis
BACKGROUND
Multiple surgical options exist for the treatment of patellar instability; however, the most common procedures involve either a reconstruction of the medial patellofemoral ligament (MPFL) or a repair/plication of the MPFL and medial soft tissues.
PURPOSE
To perform a network meta-analysis of the randomized controlled trials (RCTs) in the literature to compare MPFL reconstruction, MPFL repair, and nonoperative management for patellar instability.
STUDY DESIGN
Systematic review and network meta-analysis; Level of evidence, 1.
METHODS
The literature search was performed based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. RCTs comparing MPFL reconstruction, MPFL repair, and nonoperative management for patellar instability were included. Clinical outcomes included recurrent instability (including both dislocations and subluxations), redislocation, and Kujala score. Clinical outcomes were compared using a frequentist approach to network meta-analysis, with statistical analysis performed using the statistical software R. The treatment options were ranked using scores.
RESULTS
There were 13 RCTs with a total of 789 patients, all with a minimum follow-up of 24 months. There were 150 patients treated using MPFL reconstruction, 353 treated using MPFL repair, and 286 treated nonoperatively. Overall, MPFL reconstruction had the highest score (0.9967) and resulted in a significantly lower recurrence rate than did MPFL repair (odds ratio [OR], 0.42; 95% CI, 0.07-0.72) and nonoperative management (OR, 0.09; 95% CI, 0.03-0.32). In addition, MPFL repair resulted in a significantly lower recurrence rate than did nonoperative management (OR, 0.42; 95% CI, 0.25-0.70). MPFL reconstruction had the highest score (0.9651) and resulted in a significantly higher Kujala score than did nonoperative management (mean difference, 10.45; 95% CI, 0.41-20.49) but not MPFL repair (mean difference, 0.15; 95% CI, 0.03-0.68). Subgroup analysis revealed that MPFL reconstruction had the highest score for all outcomes in those with first-time dislocation.
CONCLUSION
The current study demonstrated that MPFL reconstruction results in the lowest rate of recurrent patellar instability and best functional outcomes as measured using the Kujala score.

Review
INTRODUCTION
Chondral and soft tissue injuries can be associated with first time patellar dislocation, but it is unclear how common they are, and which tissues are affected. A systematic review of the literature was performed to investigate the frequency, location, and extent of chondral and medial patellofemoral ligament (MPFL) injuries in patients following first time patellar dislocation.
METHODS
This systematic review was conducted according to the PRISMA guidelines. PubMed, Google Scholar, Embase, and Web of Science databases were accessed in November 2021. All the published clinical studies reporting the frequency, location, and extent of soft tissue lesions following first time patellar dislocation were accessed. Studies reporting data on habitual, congenital, or recurrent patellofemoral instability were excluded.
RESULTS
Data from 42 articles (2254 patients, mean age 21.6 ± 7.3 years) were retrieved. Ninety-eight percent of patients who experienced first time patellar dislocation demonstrated MPFL rupture at MRI. Forty-eight percent of MPFL ruptures were located at the patellar side, 34% at the femoral insertion site, and 18% in the midportion. Eighty-five percent of patients showed signs of patellar chondral damage at MRI, and trochlear chondral injuries were evidenced in 47% of patients. Intra-articular loose bodies were observed in 11.5% of patients. At arthroscopy, the medial facet and the crest of the patella more commonly exhibited chondral lesions than the lateral facet and femoral trochlea.
CONCLUSIONS
Most patients suffer chondral damage and MPFL tears following after a first time patellar dislocation.

Review
INTRODUCTION
Exergames are a fun, engaging, and interactive form of exercise that has been used in rehabilitation. This systematic review aimed to evaluate the effectiveness of exergames compared to usual rehabilitation after anterior cruciate ligament reconstruction.
METHOD
We performed a Systematic Review and GRADE evidence synthesis. The PRISMA guidelines for systematic reviews were followed. MEDLINE® (Medical Literature Analysis and Retrieval System Online), CINAHL® (Cumulative Index to Nursing and Allied Health Literature), SPORTDiscus, SCOPUS, SciELO (Scientific Electronic Library Online), Cochrane Central Register of Controlled Trials, and PEDro (Physiotherapy Evidence Database) were searched from their first record to May 2021. Randomised controlled trials using exergames as an intervention were included.
RESULTS
Initial literature searches yielded 794 non-duplicated records. After exclusion based on title, abstract, and full text review, five articles were included for analysis. Compared with the control group, the participants in the exergames group showed differences in proprioception and flexion angle difference.
CONCLUSION
Although there is no conclusive evidence that favours exergames over traditional rehabilitation, they did not aggravate the effects of rehabilitation. Nonetheless, exergames can be safe and motivating.
