Secondary Knee Osteoarthritis due to Neurofibromatosis Type 1 Treated with above the Knee Amputation: A Case Report

Background. Neurofibromatosis Type 1 (NF-1) has a variety of associated orthopaedic manifestations that have been previously reported. We report a case of severe, grade 4 knee osteoarthritis (OA) with recurrent subluxation and joint laxity due to multiple extra-articular neurofibromas ultimately treated with Above the Knee Amputation (AKA). Case Description. A 39-year-old man presented with mul...

Knee Fusion or Above-The-Knee Amputation after Failed Two-Stage Reimplantation Total Knee Arthroplasty

Prosthetic joint infection (PJI) is a serious complication of total knee arthroplasty (TKA). Control of infection after a failed two-stage TKA is not always possible, and the resolution of infection may require an above-knee amputation (AKA) or a the-knee (KF). The purpose of this review is to determine which treatment method (AKA or KF) yields better function and ambulatory status for patients...

22 Above - knee Amputation

Knee disarticulation versus above-knee amputation.

If below-knee amputation is impossible, knee disarticulation should be considered before above-knee amputation, regardless of age and etiology. Knee disarticulation which leaves the femur and patella untoched offers many advantages. The surgical technique is simple and non-traumatic since no bone or muscle tissue is to be dissected. The thigh muscles are completely preserved and thus there is n...

A Case of Above Knee Amputation with Preoperative High Risks

An 85-year-old malnourished man was admitted with ischemia-induced necrosis of the right leg and high-risk factors, including chronic obstructive pulmonary disease, pneumonia, and infection of the necrotic leg. We controlled the infection and provided proper nutrition. Using light general anesthesia and a nerve block, we amputated the leg above the knee. The patient could eat and drink the same...
