Meniscus partially or completely removed people training the first day after surgery can start to do straight leg raising exercises: the affected knee as straight as possible, lift the leg 20cm from the bed, lift up off the bed as many times as possible, each time the time insisted on as long as possible, the purpose is to increase muscle strength without increasing the pain of the swollen limb. 3-5 days after surgery, the pain and swelling of the affected limb basically disappeared, the patient can be assisted to sit at the head of the bed to practice the active lifting of the knee joint, flexion and extension exercises, pay attention to the protection of patients during exercise to prevent falls, to the extent that the patient does not feel pain, the process of exercise should be more encouragement to stimulate the enthusiasm of patients to exercise, increase the motor ability, every 10-20 minutes of flexion and extension can be wrapped in an ice bag with a towel cold compress for 5 minutes to reduce The exercise site fever reaction. If the meniscus is partially or fully resected, the affected limb can be taken out of bed with the aid of an abductor 3-5 days after surgery and gradually move with weight as the affected knee can tolerate. If there is a meniscal suture, to reduce the tension at the suture, the limb should be protected with a chuck brace and braked for 3 weeks after surgery. 3 weeks later, the limb should be trained to move within the range of motion (within 30 degrees) under protection to promote healing and shaping of the meniscus. 6 weeks later, the limb should be weight-bearing with the brace, and the brace should be removed after 8 weeks. Early training should be gradual, always practice sitting before getting out of bed, then crutches to move on the floor when accompanied to prevent postural hypotension from falling on the patient. Training goals (1) Partial or total meniscectomy: complete knee extension within 2 weeks, 90 degrees of knee flexion within 4 weeks, and normal knee flexion angle (same as the contralateral side) within 8-12 weeks. (2) For meniscal suture: not forced, gradual progress is required. It is normal for the knee to continue to swell after meniscus surgery, and it will improve on its own after 2-3 months. Occasional popping of the knee joint after meniscus surgery is normal. It is caused by the postoperative intra-articular scar, and will gradually improve on its own after 2-3 months.
