Brief summary

Advance Knee osteoarthritis is treated by Total knee replacement. Since the first TKR in 1973 there has been continuous advance in implant technology as well as operative technique, yet current patient satisfaction after the procedure is accepted to be about 80%. There are a few operative techniques to perform TKR. Until recently the most common technique is the anterior approach to the knee and then using mechanical instrumentation to make the bone cuts for the femur and tibia. A second popular technique is the anterior approach to the knee and then using a kinematic alignment to make the bone cuts. The investigators wish to compare short term results of the two operative techniques as evidenced in patient objective functional scores and also by evaluating the gait of the patients by using the REHAGAIT ANALYZER PRO by HASOMED inc. Magdeburg Germany.
