Figure 3. Reconstructive AKA with primary RPNI. A 75-year-old woman with a history of total left knee arthroplasty complicated by chronic peri-prosthetic infection who underwent multiple surgeries with poor bone and soft tissue availability underwent removal of hardware and left AKA. (A) The tibial and peroneal components of the sciatic nerve were dissected. (B) Small muscle grafts roughly 2 cm × 4 cm were taken from the nearby semitendinosus. (C) The tibial and peroneal components of the sciatic nerve are wrapped with the muscle grafts for RPNI. (D) The AKA incision was closed in layers over a drain. AKA: Above-knee amputation; RPNI: regenerative peripheral nerve interface.
