Knee arthroscopy is an advanced orthopedic procedure that combines precise diagnosis with targeted treatment of intra articular knee problems. Using specialized instruments inserted through small portals, surgeons can repair or remove damaged tissues such as torn meniscus, loose bodies, or inflamed synovium. It is widely preferred over open surgery due to its lower complication rates, shorter hospital stay, and quicker return to normal activities. The procedure is typically performed under regional or general anesthesia and is often completed on a day care basis. Postoperative rehabilitation plays a key role in recovery, focusing on restoring joint mobility, strengthening muscles, and ensuring long term knee stability and performance.
