On the first day after surgery, you can do straight leg raising exercises: straighten the knee joint of the affected side as much as possible, lift the leg 20cm away from the bed, lift up and leave the bed as many times as possible, and insist on each time for as long as possible, with the aim of increasing muscle strength without increasing the pain of the swollen limb. Postoperative 3 to 5 days of pain and swelling of the affected limbs basically disappeared, you can assist the patient sitting at the head of the bed to practice calf active lifting the knee, flexion and extension exercises, exercise, pay attention to the protection of patients, to prevent falls and injuries, to the extent that the patient does not feel the pain, the process of exercise should be more encouragement to stimulate the patient’s enthusiasm for exercise, to increase the ability to exercise, every flexion and extension of 10-20 minutes can be used with ice packs outsourcing towel cold compresses for 5 minutes in order to reduce the Every 10-10 minutes of flexion and extension, a cold compress can be applied with an ice bag and towel for 5 minutes to minimize the heat reaction of the exercise site. Postoperative bed and weight-bearing training if the meniscus partial or total resection, the affected limb can be 3-5 days after the operation to help crutches out of bed and gradually weight-bearing activities, in order to the patient’s knee can tolerate the benefits. If there is a meniscus suture, in order to reduce the tension of the suture, postoperative protection with a chuck support, braking for 3 weeks, after 3 weeks of protection to limit the range of joint activity (within 30 degrees) training activities, in order to promote the healing of the meniscus and shaping, inactivity continues to be fixed in a support. 6 weeks after the affected limb with a support for weight-bearing, the support is removed after 8 weeks. Early training should be gradual, before getting out of bed must be practiced sitting position, and then accompanied by crutches down to the ground activities, to prevent postural hypotension fall patients. Training goals: meniscus partially or completely removed: 2 weeks to achieve full extension of the knee joint, 4 weeks to reach 90 degrees of knee flexion, 8-12 weeks to reach a normal knee flexion angle (the same as the opposite side). Meniscal sutures are not imposed and need to be gradual. Knee swelling: It is normal for the knee to remain swollen after meniscus surgery, and it will improve after 2-3 months. Knee popping after surgery: Occasional popping of the knee after meniscus surgery is normal, it is caused by the scarring in the joint after surgery, and it will gradually improve after 2-3 months.
