Limb salvage operations for osteosarcoma of the extremity usually consist of wide excision and skeletal reconstruction. Most osteosarcoma patients are anemic prior to the surgery as majority of them undergo preoperative neo-adjuvant chemotherapy; thus, it is necessary to treat anemia before and after the surgery since limb salvage operation tends to accompany significant blood loss. Despite the fact that blood transfusion has bad influence on prognosis, complication, and postoperative outcome of cancer patients, it is still considered as a standard management to fix anemia for limb salvage operations. We would like to present a case report in which the authors succeeded in performing limb salvage operations on patients with distal femur osteosarcoma without transfusion.

Chronic lateral ankle instability occurs in 10% to 20% of individuals after acute ankle sprain. The management of chronic lateral ankle instability is traditionally conservative treatment in the acute phase. On the other hand, surgical intervention is considered if conservative treatment fails and the symptoms are ongoing. This review focuses on the surgical approaches to treatment of chronic lateral ankle instability, including Broström surgical techniques, with a review of the traditional procedure and newer techniques.

Giant cell tumors of bone are benign tumors that tend to be locally aggressive and occasionally cause hematogenous metastasis to the lung, accounting for approximately 6% of all primary bone tumors. The occurrences in the ankle joint are approximately 4%, and cases in the distal fibula are particularly rare. This paper presents a case of a 21-year-old female patient with a giant cell tumor who treated with a bone endoscopy, a minimally invasive surgical method, and the structure of the bone was preserved.

An early diagnosis of popliteal artery pseudoaneurysm-a sequela of popliteal artery trauma-is difficult owing to its late presentation following total knee arthroplasty. The incidence of a popliteal artery pseudoaneurysm with a hematoma presenting only a peripheral nerve injury after total knee arthroplasty is also uncommon in the absence of common diagnostic features such as a pulsatile swelling with an audible bruit on auscultation. In the present report, we describe popliteal artery pseudoaneurysm following total knee arthroplasty.
