If the legs are not the same length after hip replacement, they can be adjusted through rehabilitation exercises, foot pads and surgery. 1. Rehabilitation exercise: If the phenomenon of unequal length of legs after hip replacement surgery occurs, you can carry out somatic compensatory rehabilitation exercise, and the phenomenon of unequal length of legs will disappear gradually by consciously carrying the longer leg through weight-bearing walking. 2. Raise the footbed: If the unequal length of legs is obvious after hip arthroplasty and cannot be recovered through rehabilitation training, the patient can adjust it by raising the shoe on the short leg side. In addition to the above methods, if necessary, surgery can be taken to correct the asymmetry of the short and long legs. If the above symptoms are not relieved after surgery, or if they are accompanied by other symptoms, you should go to the hospital in time to have the cause clarified and then give targeted treatment.
