Vastus medialis muscle flap and hemi V-Y skin flap for knee extensor and soft tissue reconstruction.
Simultaneous reconstruction of extensor mechanism and skin defect of the knee joint is a difficult problem. We present a case of a 55-year-old man with loss of patella and 9 x 6 cm skin defect after total patellectomy for infected open patellar fracture. Vastus medialis muscle flap and hemi V-Y skin flap were elevated. Vastus medialis muscle flap was advanced and sutured to the remaining patellar tendon. Hemi V-Y skin flap covered the skin defect. The wound healed uneventfully. After a follow-up period of 30 months, active range of motion of the knee joint is 0-120 degrees, and extension strength of the knee joint is [4] in a manual muscle test. He can stand on his right leg without any assistance. The combination of vastus medialis flap and hemi V-Y skin flap is a valuable option in knee reconstruction after total patellectomy.
