Patients can correct the leg shape through the following methods: First, conservative treatment: if the patient’s epiphysis has not yet completely closed, you can use the lower limb support for fixation to correct the leg shape, and at the same time, with the lower limb muscle exercise, balancing the muscles around the joints, which is conducive to the correction of the leg shape. Second, surgical treatment: if adult patients, epiphysis has been completely closed, using the above methods are not effective, need to consider surgical treatment, through the distal femur or proximal tibia osteotomy to correct the leg shape. If the elderly patients have severe osteoarthritis, or even deformity of the bone joints, they can consider artificial knee replacement to correct the leg shape. After the above methods of treatment can correct the leg shape, patients should pay attention to the protection of the knee joint to avoid the above lesions.
