Purpose The purpose of this study was to investigate clinical efficacy of posterior tibial artery perforator technique combined with iliac crest autograft in treatment of medial soft tissue and medial malleolus loss. Methods This study involved 11 cases of medial soft tissue and medial malleolus loss from October 2011 to March 2016. Patients were treated with posterior tibial artery perforator technique combined with iliac crest autograft, and given routine treatment, such as rehydration, anti-inflammation, anticoagulation and vasodilation. Ankle function of patients was evaluated according to the American Orthopedic foot and ankle Association (AOFAS) ankle-hind foot scoring system. Results All flaps survived without bone exposure, and the appearance of skin flaps was satisfactory. There was one case of arterial crisis, one case of venous crisis, one case of skin edge necrosis and one case of incision infection. Wounds of the above patients were healed. Skin flap was soft and elastic without secondary contracture. The two-point discrimination of skin flap was 5–11 mm. The ankle range of motion was 10–60°. X-Ray showed that grafts healed within 8.6 months. According to AOFAS evaluation, four cases were excellent, four cases were good, and three cases were poor. The excellent and good rate was 72.8%. Conclusions In this study, posterior tibial artery perforator technique combined with iliac crest autograft was used to treat medial soft tissue and medial malleolus loss. The findings demonstrated that this treatment was reliable and efficacious.
