This study looked at how two types of knee surgery—high tibial osteotomy (HTO) alone and HTO combined with fibular osteotomy—affect the stability of knee ligaments. Researchers found that after performing a 5-degree HTO, the distance between key points of a ligament decreased by about 5 millimeters, and the space on the side of the knee increased by the same amount. Adding a fibular osteotomy after the HTO returned the knee stability to its original state, similar to an uninjured knee, which is important for maintaining knee function and stability.
Who this helps: This benefits patients with knee issues, particularly those considering surgical options for osteoarthritis or similar conditions.
