Arthroscopic reconstruction of the supraspinatus tendon represents an advanced surgical intervention for treating rotator cuff injuries. This procedure is often necessary to restore shoulder functionality in patients with significant supraspinatus tendon tears. Key aspects of post-surgery rehabilitation include several phases: the acute phase, the phase of regaining mobility, and the phase of muscle strengthening and return to full functionality. In the acute phase of rehabilitation, the focus is on reducing pain and swelling, using techniques such as cryotherapy and gentle passive exercises. The next phase, regaining mobility, involves progressively increasing the range of motion and incorporating mobility exercises, such as passive and active stretching. The muscle strengthening phase concentrates on rehabilitating strength and stabilizing the shoulder through specific strength exercises and functional activities. In addition to physical therapy interventions, proper monitoring of progress and evaluation of rehabilitation effectiveness are crucial for adjusting the therapeutic plan, with special emphasis on assessing the range of motion, muscle strength, and functional capacity. Factors such as patient age, injury severity, presence of other medical conditions, and motivation play a significant role in the success of rehabilitation. Long-term success depends on an integrated approach that considers all aspects of treatment and the individual needs of the patient. In the future, it is important to continue research to improve rehabilitation approaches and enhance treatment outcomes. Optimizing rehabilitation strategies and personalized approaches can significantly improve recovery and quality of life for patients. New approaches and technologies in physical therapy may further enhance rehabilitation results and reduce recovery time.
