Arthroscopic rotator cuff repair is a minimally invasive surgical procedure performed to reattach torn rotator cuff tendons to the humeral head. The procedure begins with diagnostic arthroscopy through standard posterior and anterior portals, with additional portals established as needed for optimal visualization and instrument manipulation.
The surgical procedure involves subacromial decompression and bursal debridement to improve visualization, followed by mobilization of the rotator cuff tendon. The surgeon then prepares the footprint on the greater tuberosity, places anchors, manages sutures, and fixes the tendon using various suture configurations including single row, double row, or transosseous equivalent techniques.
Modern rehabilitation protocols emphasize early controlled motion while protecting the repair. The accelerated recovery protocol consists of four phases. During the first four weeks, patients undergo immediate passive range of motion exercises, shoulder immobilization when not exercising, pain and inflammation management, gentle pendulum exercises, and scapular stabilization exercises. From weeks 4-8, treatment progresses to passive and active-assisted range of motion, initiation of isotonic exercises, continued scapular stabilization, and progressive rotator cuff strengthening. Weeks 8-12 involve advanced strengthening exercises, sport-specific or work-specific training, and progressive return to normal activities. The final phase, from weeks 12-24, includes full return to activities, maintenance exercise program, and completion of sport-specific training.
Research literature demonstrates favorable outcomes following arthroscopic rotator cuff repair, with 85-95% of patients reporting significant pain reduction. Patients typically return to daily activities within 4-6 months and athletic activity by 6-12 months, with high patient satisfaction rates exceeding 80%. Healing rates vary by tear size, with small tears showing 95% success, medium tears 85%, large tears 75%, and massive tears 50-60%.
Several factors affect outcomes, including age, tear size, tissue quality, smoking status, and compliance with rehabilitation. Long-term results show 10-year survival rates of 80-85%, with maintenance of function in 75-80% of cases at 5 years. Re-tear rates range from 20-40% depending on initial tear size.
Complications occur in 1-8% of cases, with infection rates below 1%, stiffness in 2-5% of cases, and variable re-tear rates based on tear size. Return to work timing varies by occupation type, with sedentary work possible at 4-6 weeks, light duty at 3-4 months, and heavy labor at 6-12 months.
The success of arthroscopic rotator cuff repair depends on multiple factors including surgical technique, tissue quality, and rehabilitation compliance. Modern accelerated protocols allow earlier return to function while maintaining repair integrity. Patient selection, appropriate surgical technique, and supervised rehabilitation remain crucial for optimal outcomes, with regular monitoring and protocol adjustments based on individual progress optimizing recovery and minimizing complications.
