Recovery time for arthroscopic subacromial decompression varies, but many patients can resume light activities within a few weeks. Full recovery, including the return to sports or strenuous activities, may take several months. Physical therapy is often prescribed to optimize shoulder strength and function. Individual factors, such as the specific procedure performed and overall health, can influence the duration of recovery after arthroscopic subacromial decompression. Regular follow-ups with the healthcare provider help monitor progress and adjust the recovery plan as needed.
