Knee injury is the most common complaint among lower extremity injuries at the Health and Sports Centre (HSC) therapy clinic of Yogyakarta State University. It is typically caused by physical contact or overuse syndrome. Knee injuries suffered by patients result in pain and lead to impaired Range of Motion (ROM) of the knee joint.
