Meta-Analysis Review
INTRODUCTION
Acromial and scapular spine stress fractures are common complications post reverse shoulder arthroplasty. A systematic review with meta-analysis was conducted to evaluate the clinical outcomes of conservatively treated acromial and scapular spine stress fractures post reverse shoulder arthroplasty in comparison to nonfracture control.
METHODS
Embase, MEDLINE, and Web of Science were searched on September 9, 2022, using various terms related to fracture, acromion, scapula, and reverse shoulder arthroplasty. Meta-analysis using a random effects model was performed on common outcome scores. Risk of bias was assessed using the Joanna Briggs Institute tools for case-controlled studies. Sensitivity analysis was performed for imputed standard deviations and studies with <20 participants.
RESULTS
Thirteen studies with a total of 339 fracture and 3142 control patients were included in the systematic review. Meta-analysis was performed on 12 studies assessing active forward flexion, abduction, external rotation, Constant-Murley score, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, pain score, Simple Shoulder Test, and Single Assessment Numeric Evaluation. Fracture patients experienced significantly poorer functional outcome compared with control patients when the fractures were managed conservatively. Levy III fractures tend to experience worse outcomes. Pain score did not demonstrate a statistically significant difference between the fracture and nonfracture cohort.
DISCUSSION
Currently, literature regarding surgical management is lacking, partially because of a dearth of high-quality literature but also hindered by a lack of standardized techniques. This review was limited by inclusion of studies of low evidence, small sample sizes, and inconsistency in outcome measurement and follow-up period. Overall, patients with acromial and scapular spine stress fractures treated conservatively are expected to have reduced shoulder function compared to nonfracture patients, with the spine of scapula fracture patients suffering the poorest outcomes. Future studies should aim to use the same sets of outcomes parameters to assess the patients at fixed time intervals and report outcomes stratified by Levy classification. This will enable interinstitutional collaboration and pooling of results.

Meta-Analysis
PURPOSE
Patients undergoing total knee arthroplasty (TKA) are at high risk for thromboembolic events compared to non-surgical patients. Both anticoagulants and antiplatelet agents are used as antithrombotic prophylaxis in TKA. The aim of this review is to understand the role of aspirin in the prevention of thromboembolic events and to compare its efficacy and safety with the main anticoagulants used in antithromboembolic prophylaxis in TKA.
METHODS
A systematic review and meta-analysis was performed according to the PRISMA guidelines. An electronic systematic search was conducted using PubMed, Scopus, and the Cochrane Central Registry to evaluate studies that compared aspirin with other anticoagulants, in terms of deep venous thrombosis and pulmonary embolism after TKA. The meta-analysis compared the rate of complications between aspirin and other anticoagulants.
RESULTS
Thirteen studies were included in the systematic review for a total of 163,983 patients, and 10 studies were included in the meta-analysis. The meta-analysis demonstrated no statistically significant differences between aspirin and other anticoagulants in terms of the rate of deep venous thrombosis (OR 0.93, 95% CI 0.81-1.08, p = 0.35) and pulmonary embolism (OR 0.89, 95% CI 0.56-1.41, p = 0.61).
CONCLUSION
Aspirin is safe, effective, and not inferior to other main anticoagulants in preventing thromboembolic events following TKA.

Review
This systematic review aims to assess the contemporary literature on the incidence rate, functional scores, and clinical outcomes of heterotopic ossification (HO) following shoulder arthroplasty. We conducted a thorough literature search on EMBASE, MEDLINE, and Ortho Search to identify studies that directly compared patients with and without HO following hemiarthroplasty, anatomic total shoulder arthroplasty (aTSA), or reverse total shoulder arthroplasty (rTSA). We included studies with a minimum follow-up period of one year published from January 2000 to March 2023. We excluded case reports, editorials, and reviews. We performed the systematic review in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Of the 297 studies initially identified, seven met our inclusion criteria. These studies evaluated a total of 1,134 arthroplasties (212 hemiarthroplasties, 376 aTSAs, and 546 rTSAs). The mean follow-up period was 30.52 (12-120) months and the mean age was 68.69 (20-92). The overall incidence rate of HO was 26.8% (304/1,134). Male gender was associated with a higher incidence rate of HO in three studies. No statistically significant difference was noted in symptoms at follow-up or in Constant-Murley score at two years of follow-up (HO vs. non-HO: 70 vs. 75, p = 0.081). Only one study reported a significant difference in the post-arthroplasty range of motion, specifically in forward elevation (121° vs. 133°, p = 0.0087) and external rotation (19° vs. 25°, p-value = 0.0266). We conclude that HO after shoulder arthroplasty does not display a significant impact on postoperative symptoms or functional outcomes in the majority of patients. To fully comprehend its effect, further research and consensus among experts is necessary.

Meta-Analysis Review
PURPOSE
Muscular strength loss and atrophy are postoperative complications. This systematic review with meta-analysis investigated the course of on knee extensor mass and strength from pre-surgery over total knee arthroplasty to rehabilitation and recovery.
METHODS
A systematic literature search was conducted in PubMed (Medline), Cochrane Library (CINAHL, Embase) and Web of Science (until 29th of June 2022). Main inclusion criteria were ≥ 1 preoperative and ≥ 1 measurement ≥ 3-months post-operation and ≥ 1 objective assessment of quadriceps strength, muscle mass or neuromuscular activity, measured at both legs. Studies were excluded if they met the following criteria: further impairment of treated extremity or of the contralateral extremity; further muscle affecting disease, or muscle- or rehabilitation-specific intervention. The Robins-I tool for non-randomized studies, and the Cochrane Rob 2 tool for randomized controlled studies were used for risk of bias rating. Pre-surgery, 3 months, 6 months and 1 year after surgery data were pooled using random effects meta-analyses (standardized mean differences, SMD, Hedge's g) in contrast to the pre-injury values.
RESULTS
1417 studies were screened, 21 studies on 647 participants were included. Thereof, 13 were non-randomized controlled trails (moderate overall risk of bias in most studies) and 7 were randomized controlled trials (high risk of bias in at least one domain in most studies). Three (k = 12 studies; SMD = - 0.21 [95% confidence interval = - 0.36 to - 0.05], I = 4.75%) and six (k = 9; SMD = - 0.10 [- 0.28 to - 0.08]; I = 0%) months after total knee arthroplasty, a deterioration in the strength of the operated leg compared with the strength of the non-operated leg was observed. One year after surgery, the operated leg was stronger in all studies compared to the preoperative values. However, this increase in strength was not significant compared to the non-operated leg (k = 6, SMD = 0.18 [- 0.18 to 0.54], I = 77.56%).
CONCLUSION
We found moderate certainty evidence that deficits in muscle strength of the knee extensors persist and progress until 3 months post-total knee arthroplasty in patients with end-stage knee osteoarthritis. Very low certainty evidence exists that preoperatively existing imbalance of muscle strength and mass in favor of the leg not undergoing surgery is not recovered within 1 year after surgery.

Shoulder & Elbow Oct 2023We conducted a review of current literature to examine the effects of smoking and smoking cessation on shoulder arthroplasty surgery. (Review)
Review
BACKGROUND
We conducted a review of current literature to examine the effects of smoking and smoking cessation on shoulder arthroplasty surgery.
METHODS
A literature search was performed using the search terms "shoulder arthroplasty AND [smoke OR smoking OR tobacco OR nicotine]." Studies included English-language clinical outcomes studies on anatomic total shoulder arthroplasty (TSA), reverse TSA, and partial shoulder arthroplasty with evidence levels 1 through 4. Descriptive statistics calculated in the included studies were used during the analysis. Categorical variables were reported as proportions, while continuous variables were reported as means with minimum to maximum absolute ranges.
RESULTS
Twenty-four studies were included and analyzed. Following TSA, patients who quit smoking at least 1 month preoperatively had improved outcomes compared to current smokers. Current smokers had statistically significant higher pain scores or opioid use. Five studies found increased rates of revision surgery in smokers. Smokers were significantly ( < 0.05) more likely to have increased rates of surgical, wound, superficial, and deep surgical site complications.
DISCUSSION
Former smokers had lower complication rates and visual analog scale scores when compared to current users. A period of four weeks or more of preoperative smoking cessation is recommended.

Review
PURPOSE
Total hip arthroplasty (THA) has demonstrated excellent results in elderly patients, however, the indications, outcomes, and long-term results in adolescent patients are less understood. This study aims to assess the outcomes of THA in patients under 21, providing insights for clinical decision-making in this exceptional population.
METHODS
A systematic review in PubMed, Ovid MEDLINE, and Embase database was performed. We included studies reporting clinical, radiological, and functional outcomes of THA in patients younger than 21 years, for any cause, with a with a minimum follow-up of one year. The ten year survivorship estimate was pooled using a meta-analysis methodology and each study was weighted according to its standard error, calculated from published confidence intervals.
RESULTS
We included 25 studies involving 1166 hips. Median age was 17 years old, 60% were females, and the average follow-up was 8.1 years. Juvenile inflammatory arthritis was the main indication for total hip arthroplasty (THA). The all-cause revision rate was 14.4% and aseptic loosening was the most common cause. Only eight studies reported ten year survival rates and form the pooled analysis an 84.91% survival rate (95% CI 70.56 - 99.27) was obtained. An average score of 88.08 in the Harris Hip Score (HHS) was observed. We found a 3.43% complication rate.
CONCLUSIONS
Hip arthroplasty is an acceptable option for adolescents with end-stage arthritis. However, the altered hip anatomy, the elevated revision rate, and the long-term implant survival must be considered before performing a THA in adolescent patients.

Meta-Analysis Review
HYPOTHESIS
Reverse shoulder arthroplasty (RSA) has become an increasingly popular treatment option for proximal humerus fractures in the elderly. There is however contradictory evidence on the impact of timing of RSA on patient outcomes. It remains unclear if poor results after initial nonsurgical or surgical management can be improved with delayed RSA. The aim of this systematic review and meta-analysis is to compare the outcomes of acute RSA and delayed RSA for the treatment of proximal humerus fractures in the elderly.
MATERIALS AND METHODS
A systematic search was performed on 4 databases for studies that compared acute RSA with RSA used after prior nonoperative or operative treatment. Studies with a mean cohort age of <65 years were excluded. Demographical data, clinical outcome scores, range of motion measurements, and postoperative complications were collected from the included studies.
RESULTS
Sixteen studies were included for data analysis. Compared with delayed RSA cohorts, acute RSA cohorts had higher forward flexion (124.3° vs. 114.9°; P = .019), external rotation (24.7° vs. 20.2°; P = .041), and abduction (113.2° vs. 99.8°; P = .03). Compared with RSA after conservative management, acute RSA had greater external rotation (29.9° vs. 21.4°; P = .043). The acute RSA cohort had significantly higher American Shoulder and Elbow Surgeons (76.4 vs. 68.2; P = .025) and Constant-Murley scores (65.6 vs. 57.3; P = .002) compared with the delayed RSA cohort. Subgroup analyses showed significantly greater Constant-Murley (64.9 vs. 56.9; P = .020) and Simple Shoulder Test scores (8.8 vs. 6.8; P = .031) with acute RSA compared with RSA after conservative treatment. The American Shoulder and Elbow Surgeons score was higher in the acute RSA cohort compared with RSA after open reduction internal fixation (77.9 vs. 63.5; P = .008). The overall complication rate per 100 patient-years was 11.7 for the acute RSA cohort and 18.5 for the delayed RSA cohort (risk ratio: 0.55; P = .015).
CONCLUSION
Based on the current evidence, acute RSA presents better clinical outcome measures and range of motion measurements, with decreased complication rates than RSA performed after prior nonoperative or operative treatment.

Meta-Analysis Review
Scaffold- and graft-based biological augmentation of rotator cuff repair: an updated systematic review and meta-analysis of preclinical and clinical studies for 2010-2022.
BACKGROUND
Despite advancements in the surgical techniques of rotator cuff repair (RCR), there remains a high retear rate. Biological augmentation of repairs with overlaying grafts and scaffolds may enhance healing and strengthen the repair construct. This study aimed to investigate the efficacy and safety of scaffold-based (nonstructural) and overlay graft-based (structural) biological augmentation in RCR (excluding superior capsule reconstruction and bridging techniques) in both preclinical and clinical studies.
METHODS
This systematic review was performed in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, as well as guidelines outlined by The Cochrane Collaboration. A search of the PubMed, Embase, and Cochrane Library databases from 2010 until 2022 was conducted to identify studies reporting the clinical, functional, and/or patient-reported outcomes of ≥1 biological augmentation method in either animal models or humans. The methodologic quality of included primary studies was appraised using the Checklist to Evaluate a Report of a Non-pharmacological Trial (CLEAR-NPT) for randomized controlled trials and using the Methodological Index for Non-randomized Studies (MINORS) for nonrandomized studies.
RESULTS
A total of 62 studies (Level I-IV evidence) were included, comprising 47 studies reporting outcomes in animal models and 15 clinical studies. Of the 47 animal-model studies, 41 (87.2%) demonstrated biomechanical and histologic enhancement with improved RCR load to failure, stiffness, and strength. Of the 15 clinical studies, 10 (66.7%) illustrated improvement in postoperative clinical, functional, and patient-reported outcomes (eg, retear rate, radiographic thickness and footprint, and patient functional scores). No study reported a significant detriment to repair with augmentation, and all studies endorsed low complication rates. A meta-analysis of pooled retear rates demonstrated significantly lower odds of retear after treatment with biological augmentation of RCR compared with treatment with non-augmented RCR (odds ratio, 0.28; P < .00001), with low heterogeneity (I = 0.11).
CONCLUSIONS
Graft and scaffold augmentations have shown favorable results in both preclinical and clinical studies. Of the investigated clinical grafts and scaffolds, acellular human dermal allograft and bovine collagen demonstrate the most promising preliminary evidence in the graft and scaffold categories, respectively. With a low risk of bias, meta-analysis revealed that biological augmentation significantly lowered the odds of retear. Although further investigation is warranted, these findings suggest graft and scaffold biological augmentation of RCR to be safe.

Review
BACKGROUND
With advancements in the technology, techniques, and biomechanical understanding of shoulder arthroplasty, higher rates of postoperative return to various sports have been seen in the past decade.
PURPOSE
To observe the return-to-golf rate after various types of shoulder arthroplasty (anatomic total shoulder arthroplasty [TSA], hemiarthroplasty [HA], and reverse total shoulder arthroplasty [RSA]) and also to review the protocols for return to golf.
STUDY DESIGN
Scoping review; Level of evidence, 4.
METHODS
The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed in a search of PubMed, JSTOR, Google Scholar, ScienceDirect, and CORE using the keywords "return to sport,""shoulder arthroplasty,""golf,""TSA,""shoulder arthroplasty,""hemiarthroplasty,""reverse shoulder arthroplasty,""RSA,""sports," and "athlete." Of 145 preliminary results, 10 retrospective studies (n = 178 patients) published between 1998 and 2021 were included in the final analysis.
RESULTS
The mean patient age was 65 years. Of the 172 patients with reported return-to-sport rates, the mean return-to-golf rate was 75.8% for all types of shoulder arthroplasty. Of these 172 patients, 107 patients were categorized by type of procedure: Anatomic TSA had the highest return-to-golf rate at 77.6% (49/107), followed by HA at 64.3% (14/107) and RSA at 59.1% (44/107). Four studies commented on return to the full 18 holes of golf, with a return-to-sport timeline ranging from 5 to 6 months postoperatively. One study specified the return-to-golf timeline based on the type of shot and reported the mean number of weeks before putting, chipping, and returning to the course as 20, 22, and 27 weeks, respectively. Two studies that reported on golf playing frequency noted an increase from before to 1 year after TSA, from a mean of 1.6 and 0.7 times per week to 2.0 and 1.7 times per week, respectively. Only 1 study, published in 1998, provided a comprehensive return-to-golf protocol.
CONCLUSION
The return-to-golf rate after shoulder arthroplasty was highest after anatomic TSA (78%) compared with HA (64%) and RSA (59%). The most commonly reported duration before returning to a full 18 holes was 5 to 6 months, but patients returned to putting and chipping earlier.

Computerized Versus Traditional Approaches for Total Knee Arthroplasty: A Quantitative Analysis of Knee Society Score and Western Ontario and McMaster Universities Osteoarthritis Index.
Total knee arthroplasty (TKA) is a common surgery for osteoarthritis, with increasing prevalence expected in the near future. This systematic review and meta-analysis compared the effectiveness of computerized TKA versus traditional TKA, focusing on postoperative outcomes measured by the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and the Knee Society score (KSS). A search on PubMed and Cochrane databases on November 14, 2023 for retrospective randomized controlled trials (RCTs) yielded data on WOMAC and KSS. The search strategy was predefined, and methodological quality of studies was critically appraised. Two researchers extracted data. Unpaired t-testing assessed the mean monthly changes in KSS and WOMAC for computer-aided versus traditional TKA. Review Manager 5.3 was used for data synthesis and analysis. Out of 729 records, five RCTs enrolling 339 patients were eligible and analyzed using a random effects meta-analysis. The mean monthly ΔKSS score differed significantly between the traditional and computerized groups (11.47 ± 8.76 vs. 9.26 ± 6.05, respectively; p < 0.01). However, the pooled mean difference estimate showed no significant differences (D = 0.20, 95% CI = -0.53 to 0.93, p = 0.59), with high heterogeneity (I = 85%, p < 0.001). The mean monthly ΔWOMAC score also differed significantly (-14.18 ± 21.54 vs. -18.43 ± 20.65, respectively; p < 0.05), but again, no significant differences were found in the pooled estimate (D = 0.17, 95% CI = -0.46 to 0.79, p = 0.60), with moderate heterogeneity (I = 28%, p = 0.24).There is no significant difference in KSS or WOMAC outcomes between traditional and computerized TKA. The study suggests the need for further research with longer follow-up periods, more timepoints, and a broader range of patient outcome measures to fully evaluate the advantages and disadvantages of each method.
