Rotationplasty of the hip joint is a special surgical technique used for the treatment of malignant tumors of the proximal part of the femur. We report a clinical case and gait analysis results before and after rehabilitation training. Evaluation of joint motion, kinetic moments, and the electromyographic findings enabled us to document progressive adaptation of muscle and joint function to their new role in the motor pattern, demonstrating the exceptional strength of rotationplasty. Active control of two fulcrums in the lower limb, the pseudo hip proximally and the pseudo knee intermedially, makes this type of operation extremely advantageous compared to the alternative of hip disarticulation or hemipelvectomy. Total absence of pain together with the preservation of articular and cutaneous proprioception are important advantages. Rotationplasty is an attractive alternative for treatment of malignant tumors of the proximal part of the femur.
