Abstract
Skin necrosis and prosthetic subluxation are dreaded complications after total knee arthroplasty. It can result in deep infection with subsequent failure of prosthesis. The incidence of infection in patients with rheumatoid arthritis who undergo knee arthroplasty is high when compared to patients with primary osteoarthritis. The gastrocnemius muscle flap has been described for cover of proximal tibia and tendon loss because of malignancy and has been used as a bridge graft in trauma patients with patellar tendon loss. We describe a patient with total knee arthroplasty with anterior knee skin necrosis and prosthesis subluxation because of attenuation and loss of continuity of patellar tendon. This was managed by using gastrocnemius bridge grafting. Here, the gastrocnemius bridge graft was used as a soft tissue cover as well as a dynamic anterior stabilizer for the prosthesis.
