ABSTRACT
We present a knee osteotomy procedure that we have termed the interlocking open-wedge distal tibial tuberosity osteotomy. In this context, the term interlocking pertains to the manner in which the repositioned segments of the retro-tubercle seamlessly fit together as the transverse osteotomy opens to the intended corrective angle. This interlocking mechanism, serving as a distinctive feature, engenders a stable retro-tubercle configuration resembling a mortise-and-tenon joint. The distal end of the tibial tuberosity fits snugly behind the tibial diaphysis, augmenting stability and promoting the healing process. Consequently, poor union of the retro-tubercle caused by the widening of the retro-tubercle gap and an increase in posterior tibial slope are effectively prevented. In addition, the need for complementary hardware such as anteroposterior screw fixation, which is used to secure the retro-tubercle during the healing process, is notably eliminated. This elimination not only simplifies the surgical procedure but also eliminates potential complications that could arise from its use.
