One treatment modality for medial osteoarthritis of the knee is open-wedge high tibial osteotomy (HTO). The current most common way of performing HTO is to use fixation plates with locking bolts implanted in the patient's tibia, to allow increased stability & joint movement and the ability to be weight bearing on the affected leg sooner . However, despite advances in high tibial osteotomy technology, it can still take most patients about six months to fully recover from the procedure. Sedentary activities are usually picked up about a month after surgery, before physical work is introduced 3 to 4 months after surgery, followed by sports which can be reintroduced approximately 6-12 months after surgery. One reservation for allowing patients to be fully weight bearing early on is the perceived risk of loss of correction of the angle, although in practice this effect appears to be a rare occurrence . For example, in a series of patients Takeuchi and colleagues showed that full weight-bearing is possible two weeks after surgery without implications for the correction made to the joint angle .
