1. Straight leg lifting exercise. Lie on your back, straighten the affected knee and raise it by 30 ~ 40 cm. Try to keep this posture. If you can't hold on, you can take a break, which is 1 time. Then repeat the exercise, each group 10 ~ 15 times, twice a day. If you can persist for more than 1 min, you can carry out weight-bearing straight leg lifting exercises.
Load-bearing straight leg lifting exercise: the action is the same as above, and the instep can bear a certain weight, starting from 1 kg and gradually increasing to 5 kg. If you can persist for more than 1 minute, then proceed to the next exercise.
Load-bearing short arc exercise: The patient sits by the bed, with a pillow under the affected knee and bends his knees 30 degrees. The load of the affected foot starts from 5 kg and gradually increases to 10 kg. Sit and lift his legs straight. If he can persist for more than 1 minute, he can go to the next exercise.
Load-bearing long arc exercise: sitting by the bed, knees bent 90 degrees, legs drooping. The load of the affected foot starts from 10 kg and gradually increases to 20 kg.
2. Sit down and stretch your knees. The patient sits on the bed, the affected knee is as straight as possible, the instep is flat, the ipsilateral hand presses the knee down, and the contralateral hand bends the waist enough.
Knee-sitting, swinging, flexion and extension: when sitting on the bed, the affected limb droops, and the healthy limb helps to press the affected limb and increase flexion.
Supine knee flexion exercise: supine, the affected limb bends the hip 90 degrees, and the affected knee bends as much as possible. The healthy limb helps to press the affected calf and increase knee flexion.
Kneeling posture exercise: the patient kneels on the bed and kneels backwards to increase the knee flexion angle.
3. Lie flat and "pedal for three rounds". Lie in bed every morning and evening and imitate three rounds of movements. Lying flat can reduce the burden of vulnerable joints, and this action can exercise all joints from ankle joint to shoulder joint.
4. Exercise in the water. Patients can do appropriate water sports, such as swimming. The buoyancy of water can reduce the pressure of weight on the knee joint, at the same time, it is helpful to strengthen the cardiopulmonary function of patients, improve muscle endurance and relieve osteoarthritis. Even if you accidentally fall, it is not easy to cause sports injuries.
