Partial and complete tears can occur, with symptoms such as pain, swelling, tenderness, and cramping. Diagnosis is made through a physical examination and imaging tests such as X-rays and MRI scans.
Treatment options include non-surgical and surgical approaches. Non-surgical treatments may involve braces or splints and physical therapy, while surgery involves reattaching the torn tendon to the kneecap. Complications such as weakness, loss of motion, and re-rupture can occur, and healing may take up to six months.
