High Tibial Osteotomy (HTO) is an accepted means of improving the symptoms of a knee deformity such as genu varum. Patient's symptoms may improve by off-loading the diseased medial compartment of the knee by changing the axis of alignment. This means that loading of the knee joint changes to the less diseased lateral compartment by an osteotomy and opening wedge thereby reducing pain, swelling, and stiffness associated with arthritis. By implication this is major surgery and requires careful preoperative assessment taking into account, patient factors, joint geometry and degree of disease in affected and less affected compartments. This study analyzes the effect of surgery on the ultimate length of the tibia compared to its preoperative state. Both Opening and Closing Wedge osteotomies were investigated in this study. The results showed that the length of tibia would increase following the Opening Wedge HTO and it would decrease by a Closing Wedge HTO. Although the change in the length of the tibia was small in comparison to its overall length the possibility of bone lengthening must be considered carefully when determining an Opening or Closing Wedge HTO, especially when a large correction angle is required.
