The Effect of Rotator Cuff Tears on Surgical Outcomes After Type II Superior Labrum Anterior Posterior Tears in Patients Younger Than 50 Years

Background: Rotator cuff injury in the setting of type II superior labrum anterior posterior lesions is a common finding. Although predictable surgical outcomes can be expected after type II superior labrum anterior posterior repair, the effect of rotator cuff tears on surgical outcome is unknown.

Hypothesis: Rotator cuff tears will not negatively affect surgical outcome of type II superior labrum anterior posterior repairs.

Study Design: Cohort study; Level of evidence, 3.

Methods: The study group included 93 patients younger than 50 years who underwent arthroscopic type II superior labrum anterior posterior repair and were available for review at a minimum of 2 years after surgery. Group 1 patients were identified as having normal rotator cuffs at the time of repair. Group 2 patients were identified as having rotator cuff injury at the time of repair (either partial-thickness or full-thickness tears). Statistical analysis was performed comparing the postoperative University of California, Los Angeles shoulder scores and overall improvement in University of California, Los Angeles score using the Student t test for significance.

Results: Mean follow-up was 2.54 years; 52.7% of patients had evidence of rotator cuff tears at the time of surgery. The mean postoperative University of California, Los Angeles score for group 1 was 32.9 (improvement of 11.0), and the mean postoperative University of California, Los Angeles score for group 2 was 33.3 (improvement of 12.2). There was not a significant difference in any of the outcome measures between groups.

Conclusion: Predictable short-term surgical results and return to activity can be expected after repair of type II superior labrum anterior posterior lesions in patients younger than 50 years who have coexistent rotator cuff tear. Although cuff lesions did not have a negative effect on the short-term outcome in patients with type II superior labrum anterior posterior lesions, longer-term follow-up is needed to determine natural history of this pathologic condition.
