[0055] Overview of Open Wedge High Tibial Osteotomy

[0056] see first Figure 1-3 , shows the knee joint 5 on which an open wedge osteotomy is to be performed. Knee joint 5 generally includes tibia 10 and femur 15 . According to the present invention, by first making an incision 20 in the upper tibia ( figure 1 ), and then manipulate the lower part of the tibia to open a wedge-shaped opening 25 in the bone ( figure 2 ), achieving an open wedge osteotomy, wherein the wedge opening 25 is configured so as to adjust the way the load is transferred from the femur to the tibia. In this regard, it should be appreciated that a variety of methods are known in the art for determining the degree of correction required to properly realign the weight-bearing axis of the knee. Also, the cutouts 20 and wedge-shaped openings 25 can be formed in a variety of ways well known in the art.
