In the general direction, knee squatting pain is a disease within the scope of orthopedics, and then depending on the hospital subspecialty, you can see the sports medicine department or knee joint department. If you are in a Chinese hospital, you can see the Department of Chinese Orthopedics and Traumatology or the Department of Cervical, Lumbar and Leg Pain. The most common clinical causes of pain when squatting on the knee are patellar chondromalacia, injury to the posterior meniscus, or osteophytes or osteoarthritis. Most of them are diagnosed by radiographs, clinical symptoms and positive signs, or MRI, and the treatment is basically the same, with light conservative treatment, such as intra-articular injection of sodium glutamate, or oral glucosamine, with physical therapy, etc. In severe cases, minimally invasive arthroscopic surgery can be done. This is mostly for older patients.
