PAIN IS THE MOST FREQUENTLY CITED REASON ATHLETES FAIL TO RETURN TO SPORT AFTER ULNAR COLLATERAL LIGAMENT SURGERY: A SYSTEMATIC REVIEW AND META-ANALYSIS
Figure 1 - PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) flowchart of study inclusion.
Background: No previous systematic review to our knowledge has examined the reasons that athletes fail to return to sport (RTS) after ulnar collateral ligament (UCL) surgery.
Purpose: To report the rate of failure to RTS after UCL surgery and identify reasons that preclude an athlete's ability to successfully RTS.
Study design: Systematic review; Level of evidence, 4.

Methods: This study was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We searched the PubMed, Scopus, and SPORTDiscus databases for studies on athletes who underwent either UCL reconstruction or repair that reported RTS rates and identified reasons for failure to RTS. Data were collected on the number of athletes included, average age, sport played, operative technique, average follow-up, rate of failure to RTS, and reasons for failure to return. A random-effects model was used to conduct the meta-analysis.

Results: Included were 26 studies reporting on 1019 athletes. Primary or revision UCL reconstruction was performed in 913 patients (89.6%), while the remaining 106 patients (10.4%) underwent UCL repair. The pooled rate of failure to RTS after UCL reconstruction or repair was calculated to be 11.4% (95% CI, 8.4-14.7). A significantly higher estimated proportion of athletes failed to return because of elbow-related reasons compared with non-elbow-related reasons (55.3% vs 40.6%; P = .0352). Persistent pain (29/103; 28.2%) was the most common reason for failure to return, followed by elbow limitations and other unspecified elbow problems (19/103; 18.4%). There was moderate evidence for publication bias and study heterogeneity across the included studies.
Conclusion: This meta-analysis estimated the rate of failure to RTS after UCL surgery as 11.4%, with the majority of athletes unable to return because of elbow pain. Future studies reporting outcomes and providing details as to why athletes are unable to RTS can better inform sport surgeons on factors precluding RTS and can guide clinical practice to better help athletes achieve their postoperative goals.
