Fig. 1Open fracture around the knee joint. (A) Necrosis of patella and loss of patella tendon. (B) After debridement, the knee joint is opened and reconstruction of quadriceps mechanism is required. (C) Medial gastrocnemius muscle flap and saphenous neurocutaneous island flap are harvested. (D, E) The gastrocnemius muscle is turned to be sutured to the quadriceps muscle. (F) The remaining defect is covered with the saphenous neurocutaneous island flap. (G) Two years later, full range of motion of the knee joint is recovered and the motor grade reaches grade 4.
Fig. 2Reverse sural artery flap. (A) Soft tissue defect at the posterior aspect of the ankle. (B) Reverse sural artery flap is designed. (C) Pedicled flap is dissected. (D) After completion of flap insetting.
Fig. 3Anterolateral thigh (ALT) flap. (A) Contaminated soft tissue defect on the anterior ankle. (B) ALT flap is designed. (C) Dissected ALT flap. (D) Flap insetting. (E) Donor site is primarily closed. (F) Two months after the operation.
Fig. 4Free vascularized fibular osteocutaneous flap. (A) Large tibia and soft tissue defect after infected open fracture. (B) Sequestrum is removed. (C, D) Free vascularized fibular graft is harvested from the ipsilateral leg. (E) Flap is fixed and repaired. (F) Two years after bone and soft tissue reconstruction.
