The shape of the legs can be corrected through braces and surgery. 1. Brace correction: for patients with mild symptoms, lower limb braces can be used to fix and correct the leg shape of stilted leg, and at the same time with the lower limb muscle exercise, balancing the weight of the muscles around the joints, which is conducive to correcting the leg shape. 2. Surgical correction: If the leg deformation is more serious and the above methods are not effective, surgical correction can be considered. The leg shape can be corrected by osteotomy of distal femur or proximal tibia. If the elderly patients have serious osteoarthritis, or even osteoarthritic deformity, they can consider artificial knee replacement to correct the leg shape. In daily life, we should try to avoid crossing our legs, maintain correct sitting and lying posture, and do appropriate sports and exercise.
