PURPOSE: We assessed the clinical results after the operative treatment of type 2 SLAP lesion with stiffness. MATERIALS AND METHODS: 13 patients who had SLAP lesion with stiffness were treated with arthroscopic capsular release, SLAP repair and treatment of the associated lesion. The average follow-up period was above 12 months. RESULTS: The postoperative mean VAS was scored 1.5 and the postoperative ROWE score was 92.3, which showed a significant improvement after the operation (P<0.001). The mean range of motion was a significantly improved after the operation (P<0.001). The ROWE score was excellent for all the cases. CONCLUSION: Arthroscopic capsular release and SLAP repair and treatment of the associated lesion in patients with type 2 SLAP lesion with stiffness are effective treatments for the increasing the range of motion and decreasing the pain.
