ABSTRACT
Patellofemoral arthritis is a clinical common type of knee osteoarthritis distinguished by its pain and anatomical position. The stability of patella is crucial to the stability of the patellofemoral joint and is related to the occurrence and development of osteoarthritis. Patella stability depends on the structural geometry of patellofemoral condyle, the static mechanics of the surrounding joint capsule, tendon, fascia, ligament and patellar ligament and the dynamic mechanics of the quadriceps. Therefore, manipulation therapy should be based on the considerations on the stability of the patella as well as TCM theory. Starting from maintaining the balance of the dynamic and static mechanical system and focusing on the restoration of the stability of patella, the ultimate goal of the treatment is to restore the stability of patellofemoral joint. The main aspects of manipulation treatment strategy include the balancing of dynamic and static mechanical system, the idea of holism treatment, differentiation treatment based on tendons injury identification, fundamental principle of softening tendons, cooperation between doctors and patients, and combination of therapy and convalesce.
