Objective: To restore the physiologic anterior and posterior capsular volume to achieve an anatomic central contact point of the glenohumeral articulation and treatment of concomitant glenohumeral injuries due to posterosuperior impingement (PSI). Indications: Plateauing of clinical improvement despite adequate nonsurgical treatment (for at least 6–12 months). Contraindications: General contraindications for elective arthroscopic surgery. Surgical technique: Diagnostic arthroscopy of the glenohumeral joint through the posterior portal to assess stability of the biceps–labral complex even in the Abduction and External Rotation (ABER) position to confirm the diagnosis of PSI and to detect concomitant glenohumeral injuries. In most cases posterosuperior SLAP (superior labrum anterior posterior) repair or tenodesis of the long head of the biceps. Postoperative management: Arm sling for 6 weeks with limited range of motion. Free active range of motion of elbow and wrist. Limited shoulder external rotation for 6 weeks. Free shoulder range of motion from week 7, full daily life activities after 12 weeks. Modification of the postoperative management according to intraoperative findings. Results: At our hospital 18 overhead athletes (6 women, 12 men, mean age 31 years) with PSI without SLAP lesion or rotator cuff tear underwent isolated plication of the anteroinferior capsule after primary nonsurgical treatment. At a mean period of 9 months, 16 patients returned to their pre-injury sports activity level, 2 patients had to give up their sports due to persisting shoulder problems. At a mean follow-up of 27 months (range 12–55 months) the Walch Duplay score was on average 82.9 ± 8.3 for men and 73.8 ± 5.9 for women.
