High Tibial Osteotomy is another type of surgery used to treat arthritis. This procedure mainly aims to correct the damaged knee caused by arthritis. It does not return the normal functioning of the knee. However, it relieves pain and other discomforts. In addition, the need for total knee replacement is also delayed. During this surgery, the bone of the leg is realigned. This is achieved by taking out the triangular wedge of the bone from the outer portion of the tibia. In this way, the weight is passed to the undamaged outer part of the knee.
