In recent follow-ups of patients after patellar subluxation correction (mainly minimally invasive arthroscopic medial support band tightening + lateral support band release), we found that some patients still have the feeling of knee instability and weak legs when participating in sports activities, although they have basically resumed their daily life after surgery, considering that this phenomenon is mainly caused by the lack of muscle strength and joint flexibility in the lower limbs. Therefore, I recommend an international classic rehabilitation exercise method for patellar subluxation/hemisubluxation, which is mainly applicable to patients suffering from patellar subluxation or hemipelvectation who have not undergone surgery or are more than 6 months post-surgery, and the rehabilitation training within 6 months of surgery, it is recommended that the rehabilitation program developed by the attending surgeon and rehabilitation specialist should prevail.
