rotationplasty
Pronunciation: /roʊˌteɪʃənˈplæsti/
A limb reconstruction technique where the ankle joint is rotated and positioned to function as a knee joint following tumor resection.
Full Definition
Rotationplasty is a specialized limb reconstruction procedure typically performed for malignant bone tumors around the knee in children and adolescents. The technique involves resecting the tumor-bearing segment (usually distal femur and proximal tibia), then rotating the remaining lower leg 180 degrees and reattaching it to the residual femur. This positions the ankle joint to function as a knee joint, with the foot pointing backward. Following healing and prosthetic fitting, patients can achieve excellent functional outcomes with the ability to run, jump, and participate in sports. While the cosmetic appearance may be challenging for some patients, rotationplasty often provides superior long-term function compared to other reconstruction options.
