Long-term outcome after arthroscopic repair of type II SLAP lesions: results according to age and workers' compensation status.

PURPOSE: The purpose of this study was to determine the long-term functional outcome of anatomic arthroscopic repair of type II SLAP lesions with suture anchors.

METHODS

We examined all arthroscopic repairs of isolated type II SLAP lesions from January 2002 through December 2007. Fifty-five patients were available for long-term follow-up at a mean of 77 months. The mean patient age at the time of surgery was 39.7 years (range, 17 to 65 years); 23 patients were aged younger than 40 years, and 32 patients were aged 40 years or older. Fourteen cases involved Workers' Compensation claims.

RESULTS

Overall, functional outcome was improved from baseline compared with final follow-up for both American Shoulder and Elbow Surgeons scores (44.1 points v 86.2 points, P < .001) and University of California, Los Angeles scores (19.1 points v 31.2 points, P < .001). According to the University of California, Los Angeles grading system, 87% of cases had good or excellent results. Although the percentage of good and excellent results among patients aged 40 years or older (81%) was lower than that among patients aged younger than 40 years (97%), this difference did not reach statistical significance (P = .219). The percentage of good and excellent results among the non-Workers' Compensation cases (95%) was significantly higher than that in Workers' Compensation cases (65%) (P = .009). Overall, patient satisfaction was reported in 91% of cases, and return to normal sport or activity was reported in 82% of cases.

CONCLUSIONS

In 87% of cases, a good or excellent functional outcome can be anticipated after arthroscopic repair of type II SLAP lesions with the described techniques. Variables associated with a poor outcome include Workers' Compensation cases and possibly older age (≥40 years).

LEVEL OF EVIDENCE: Level IV, therapeutic case series.
