Type V superior labrum anterior to posterior repair: a systematic review.

ABSTRACT

BACKGROUND: The purpose of this study is to systematically review the evidence in the literature to ascertain the functional outcomes, recurrence rates, and subsequent revision rates following type V superior labrum anterior to posterior (SLAP) repair. METHODS: Two independent reviewers performed a literature search based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, utilizing the EMBASE, MEDLINE, and the Cochrane Library Databases. Studies were included if they had clinical outcomes on the patients undergoing type V SLAP repair. Statistical analysis was performed using SPSS (IBM, Armonk, NY, USA). A P value of <.05 was considered to be statistically significant. RESULTS: Our review found 13 studies, including 451 shoulders meeting our inclusion criteria. The majority of patients were males (89.3%), with an average age of 25.9 years (range 15-58) and a mean follow-up of 53.8 months. The Rowe score was the most utilized functional outcome score, with a weighted mean of 88.5. Additionally, the mean Constant score was 91.0, the mean American Shoulder and Elbow Surgeons score was 88.3, the mean subjective shoulder value score was 85.5%, and the mean visual analog scale pain score was 1.2. The overall rate of return to play was 84.8%, with 80.2% returning to the same level of play. The overall reoperation rate was 6.1%, with a recurrent dislocation rate of 8.2%. In the studies comparing type V SLAP and isolated Bankart repair, there were statistically insignificant differences in visual analog scale pain scores (mean difference; 0.15, 95% confidence interval, -0.13 to 0.44, I2 = 0%, P = .29) and recurrence rates (risk ratio; 1.38, 95% confidence interval, 0.88-2.15, I2 = 0%, P = .16). CONCLUSION: Arthroscopic repair of type V SLAP tears results in excellent functional outcomes, with high return to play rates in athletes. There are low rates of reoperations and recurrent dislocations. Additionally, in comparison to an isolated Bankart repair, SLAP repair does not increase recurrence rates or postoperative pain.
