Sitting on a bed or chair, if the bed is not high enough, you can properly pad your thighs. In short, legs can droop and feet can't touch the ground. Relax the thigh muscles, put a good leg on the affected leg, and slowly make the calf droop until it feels pain 1-2 minutes. After the pain is relieved, continue to increase the drooping angle (the leg protection can be removed with the increase of the angle later), and the total drooping time should be controlled at 15-20 minutes.

Progress and transformation: If you can easily droop your calf to an angle similar to that in the middle picture, you can add a small sandbag (1kg) to your ankle joint or gently push your healthy leg on the affected leg (without causing obvious pain) and keep it at the pain position for 1-2min. After the pain is relieved, continue to increase the drooping angle, and control the total drooping time at 10-65438+.

Tip: The above actions can be performed on the back, which can stretch and relax the front thigh muscles and further increase the bending angle.

Seat top wall:

You can do this training after sitting and hanging your legs. Sit up straight in the chair, facing the wall, and fix the affected toe on the wall. Bend the knee to the maximum angle (usually painful) to fix the position of the chair and keep it. After the pain is relieved, continue to adjust the chair and increase the knee flexion angle. The total wall pushing time is controlled in 5- 10 minutes. In this process, it is not allowed to lean or lift the affected hip to avoid compensation.

Hang your legs in a supine position:

Generally, after actively bending 90 degrees, you can do the following exercises, such as holding your thighs with your hands, relaxing your thigh muscles, and letting your calves naturally droop to the maximum angle and keep them. In this process, you should completely relax your thigh muscles and can't resist. In the later stage, a small sandbag (0.5Kg) can be added to the ankle joint, and the load cannot be too large, otherwise the muscles cannot be relaxed.

Sit on your knees:

Sit down, hold the calf with both hands, and keep the heel close to the hip for 3-5 minutes until the pain is relieved, and then continue to increase the angle. Measure the distance between heel and hip before departure, and gradually shorten it to the same angle as the healthy leg. This exercise should be done step by step, and avoid blindly pushing the angle or being afraid of pain.

Prone position drafting: when the active bending can exceed 90, the following methods can be considered to strengthen the bending angle.

Answer the question:

1. After knee replacement, it is generally required to bend the leg 90 degrees actively and100-10 degrees passively within two weeks. At this stage, you can take turns to use two methods: sitting (lying) with your legs down and sitting against the wall.

2. After the active bending angle exceeds 90, you can consider hanging your legs in supine position, sitting with your knees folded, or directly using prone position drafting method. The above methods Before the operation, the patella should be moved properly. Methods Please refer to the previous popular science article "To practice the angle after knee replacement, first learn to loosen the patella".

3. After the above exercises, ice should be applied in time according to the situation. Methods Refer to the previous popular science article "How to ice compress after knee replacement" to reduce the inflammatory reaction caused by training stimulation.

4. The above methods can be used for reference for postoperative fractures around the knee joint (including patella fracture) and postoperative sports injuries of the knee joint (cruciate ligament, meniscus, patella dislocation, etc.). ), communicate with doctors and therapists in time when encountering problems in use.
