Abstract

[Indexed for MEDLINE] 2. J Am Acad Orthop Surg. 2012 Oct;20(10):657-67. doi: 10.5435/JAAOS-20-10-657. Principles of rotationplasty. Gupta SK(1), Alassaf N, Harrop AR, Kiefer GN. Author information: (1)Department of Surgery, University of Calgary, Calgary, Canada. Rotationplasty is a reconstructive, limb-sparing option for management of lower extremity bone deficiency. This technique involves an intercalary resection, followed by 180° rotation of the distal limb to allow the ankle to function as a knee joint when it is fitted with a modified below-knee prosthesis. Gait analysis and functional outcome studies have reported favorable results with rotationplasty compared with those of above-knee amputation. Moreover, patient satisfaction with rotationplasty is higher than with other limb salvage procedures. The primary drawback of this procedure is patient acceptance of the limb's appearance.
