The proximal part of the operation is similar to a hip disarticulation. Winfried W. Winkelmann J Bone Joint Surg Am 2000;82:814 ©2000 by The Journal of Bone and Joint Surgery, Inc.

The distal part of the operation is similar to a knee disarticulation. Winfried W. Winkelmann J Bone Joint Surg Am 2000;82:814 ©2000 by The Journal of Bone and Joint Surgery, Inc.

After the leg is rotated 180 degrees, the lateral aspect of the proximal part of the tibia is placed into the acetabulum and fixed in position.

Radiographs showing sequential changes that led to conversion of the lateral aspect of the proximal part of the tibia into a new femoral head over a seven-year period.Fig. 3-A: Five weeks postoperatively, there is atrophy due to inactivity of the proximal part of the tibia. The medial part of the tibia is not well centered in the acetabulum. Winfried W. Winkelmann J Bone Joint Surg Am 2000;82:814 ©2000 by The Journal of Bone and Joint Surgery, Inc.

The medial part of the tibial physeal plate is oriented toward the vector of force. There is appositional bone growth on the medial side of the proximal part of the tibia, and the compressive trabeculae are merging into the thickened tibial cortex. Winfried W.
