Prophylactic Muscle Free Flap for Total Ankle Arthroplasty With Vascular Risk Factors.

Total ankle arthroplasty (TAA) is a treatment for ankle arthritis that preserves the joint's mobility. Conditions causing poor peripheral blood flow are contraindications for TAA. A 63-year-old man with posttraumatic ankle osteoarthritis who was considered high-risk for TAA due to obesity, history of trauma, tobacco usage, chronic venous stasis, lymphedema, and hypertension subsequently underwent TAA followed by a prophylactic muscle free flap to improve peripheral blood flow and soft tissue integrity. He recovered with no pain and excellent ankle mobility. This case highlights the potential usage of prophylactic muscle free flaps to mitigate vascular risk factors in high-risk patients undergoing TAA.
