<B>Hypothesis:</B> Impingement syndrome restricts the shoulder motion and can cause shoulder joint stiffness. This study was carried out to evaluate the functional outcome of arthroscopic surgical management for impingement syndrome with shoulder joint stiffness.<BR><B>Methods:</B> We evaluated a total of 50 shoulders with impingement syndrome, consisting of 25 shoulders with impingement syndrome alone (Group I) and 25 shoulders with impingement syndrome associated with shoulder joint stiffness (Group II). Group I shoulders were treated by arthroscopic subacromial decompression (ASD) alone and Group II shoulders were treated by ASD with capsular release. Clinical evaluation was composed of Hawkins impingement sign (+ or -), active ROM in flexion and abduction; clinical assessment with the Japanese Orthopaedic Association (JOA) shoulder scoring system at 3 and 6 months follow up. Statistical evaluation was performed between the two groups.<BR><B>Results:</B> Hawkins impingement sign was observed preoperatively in all 50 shoulders and had disappeared in all 25 shoulders of Group I at 3 months follow up. In Group II it had not disappeared in 5 shoulders (20%) at 3 months follow up, though it had disappeared in all 25 shoulders at 6 months follow up. Average active ROM in flexion and abduction was significantly improved in both Groups at 3 and 6 months follow up. JOA score was significantly higher in Group I than Group II.<BR><B>Conclusion:</B> Our results showed ASD combined with capsular release was an alternative surgical procedure for the treatment of combined lesions with subacromial impingement and shoulder joint stiffness.
