Abstract
BACKGROUND AND HYPOTHESIS: Postoperative stiffness is a commonly reported complication after type II superior labrum anterior-posterior (SLAP) repair. It is unclear whether patients with postoperative stiffness, classified as external rotation to the side of ≤20°, ultimately will have greater functional outcomes at ≥2 years after surgery. We hypothesized that postoperative stiffness would result in improved functional outcomes at ≥2 years after surgery. METHODS: Sixty-five consecutive arthroscopic SLAP repair cases performed by a single surgeon were retrospectively reviewed using prospectively collected patient-ranked outcomes and examiner-determined assessments preoperatively and at 1 week, 6 weeks, 24 weeks, and a minimum of 2 years after surgery. Patients were allocated to the stiff group and the non-stiff group based on their external rotation at 6 weeks after repair. RESULTS: Of the patients, 16 (27%) had ≤20° of external rotation at 6 weeks postoperatively. These patients, comprising the stiff group, had more pain and more difficulty with overhead activities early on than patients in the non-stiff group (very severe vs. severe, P < .05), but by 2 years, they had less difficulty and less pain with overhead activities, less patient-reported stiffness, and less severe pain at night than isolated SLAP repair patients with >20° of external rotation at 6 weeks (P < .05). CONCLUSION: This study suggests that in patients who underwent SLAP repair, early postoperative stiffness (at 6 weeks as assessed by ≤20° of external rotation), while problematic early, is associated with improved functional outcomes in the longer term, with patients in the stiff group reporting less pain and difficulty with overhead activities at ≥2 years after surgery.
