To adapt to the new joint, it is necessary to properly walk on the ground and support the normal movement and walking of the walker, which is one of the rehabilitation. 2. When lying in bed, you can take exercises for muscle strength of both lower limbs to prevent local muscle atrophy and deep vein thrombosis, and increase the strength of the muscles around the joint capsule, which is a kind of protection for the stability of the joint. 3. Remember not to do excessive inward and flexion movements, which can easily lead to joint dislocation and thus increase the patient’s burden. 4. Exercises around the joints should be performed to prevent adhesions between the joint capsule and the surrounding muscles from affecting the movement of the joints.
