A 60-year-old female underwent a right total knee arthroplasty but developed postoperative pain, swelling, and decreased knee range of motion. An ultrasound scan showed findings suggestive of fat necrosis at the site of previous tourniquet application. Following regular reviews, intensive physiotherapy, and analgesia, symptoms only started to resolve 5 months following the primary surgery. Fat necrosis of the thigh is highly uncommon following the application of tourniquets during total knee arthroplasty. This case was treated successfully without complications using nonoperative measures.
