If the knee joint can develop adhesions, local dysfunction will occur. Generally, after about three months of conservative treatment and functional training, if the results are not good, surgery should be performed as soon as possible to release the adhesions. If the knee joint adhesions are not well treated conservatively, the best time for surgical release is about three months. For knee adhesions, early functional training, including knee flexion and extension exercises, strength exercises and adjunctive therapy, including massage, manual release and functional training after local closed injection, as well as waxing, baking electricity and physical therapy, can be applied to restore and release the local adhesions. If the results are not good after three months of effort, surgical release can be performed in time. Because after three months of functional training, the time is not short, if continue to conservative treatment can not achieve better expected treatment effect, this time should be as soon as possible to surgical release treatment.
