Knee adhesions can be opened with anesthesia, but are generally indicated for severe adhesions. Knee adhesions are generally characterized by an inability to flex the knee on its own and a marked impairment in flexion and extension. They can be divided into intra-articular adhesions and extra-articular adhesions. Intra-articular adhesion is caused by intra-articular fracture, meniscus injury, etc. Extra-articular adhesion can be caused by femur fracture without timely exercise. 1. Mild knee adhesions are usually treated conservatively. If conservative treatment is ineffective, manual release under anesthesia or arthroscopic release of intra-articular adhesions can be performed. 2. If the degree of knee joint adhesion is serious, it is often necessary to open the knee joint under anesthesia to loosen the muscles and soft tissues in order to restore the knee joint adhesion. Knee adhesions can be opened under anesthesia, but should be combined with their own situation to choose the appropriate treatment, it is recommended that patients go to the hospital in a timely manner, consult the doctor, choose the appropriate treatment plan.
