Modified Rotationplasty as a Composite Free Flap for Femur and Thigh Reconstruction

Knee rotationplasty is a suitable reconstructive and limb salvage procedure for infected femur and knee prostheses. It involves external rotation of the lower limb with an intact neurovascular bundle to function as a knee joint. Functionally, it has better outcomes when compared to alternate options like above knee amputation. It results in better cortical reorganization and superior stance mechanics, enabling a more efficient gait and better quality of life. Here we report a 57-yr-old male who underwent modified rotationplasty for an infected knee endoprosthesis as a composite lower leg free flap.
