- Abstract:
- OBJECTIVE: Implantation of an acellular dermal allograft between glenoid and humerus to restore a stable glenohumeral center of rotation in cases of irreparable posterosuperior rotator cuff tears. INDICATIONS: Irreparable posterosuperior rotator cuff tears with low-grade cuff tear arthropathy (Hamada grade 1 and 2) and isolated pseudoparesis for flexion. CONTRAINDICATIONS: Absolute: Infection, nerve lesions (brachial plexus, axillary nerve), concomitant irreparable subscapularis tendon tear, anterosuperior subluxation of the humeral head ("anterosuperior escape"). Relative: Cuff tear arthropathy ≥ Hamada grade 3, fatty infiltration of the infraspinatus muscle ≥ Goutallier grade 2, deficiency of the deltoid muscle, inability to adhere to the rehabilitation program, poor compliance. SURGICAL TECHNIQUE: Arthroscopic fixation of a 6 mm thick acellular dermal allograft with three suture anchors at the superior glenoid rim and a double-row construct at the greater tuberosity. Dorsal and ventral interval closure with side-to-side sutures. POSTOPERATIVE MANAGEMENT: Abduction brace for 6 weeks with passive mobilization. Active motion exercises are commenced at 6 weeks with progression to strengthening exercises after 12 weeks. RESULTS: Between April 2019 and September 2020, 15 patients (5 women and 10 men) underwent arthroscopic superior capsule reconstruction using a 6 mm thick acellular dermal allograft for treatment of irreparable posterosuperior rotator cuff tears. After a mean follow-up of 15.4 ± 5.5 months, there was a significant improvement in active flexion (102° ± 37°preop vs. 143° ± 24°postop; P = 0.001; 95% CI 19.6-63.7), ASES score (45.5 ± 16.1preop vs. 68.2 ± 17.4postop; P < 0.001; 95% CI; 12.9-33.7) and DASH score (57.2 ± 18.6preop vs. 22.0 ± 17.4postop; P < 0.001; 95% CI; -46.0 to 24.7), along with significant pain reduction (4.5 ± 2.0preop vs. 2.5 ± 2.1postop; P = 0.001; 95% CI; -3.2 to 1.1). There were no complications requiring revision surgery.
