Arthroscopically assisted arthrodesis of the ankle joint

Abstract

In 26 patients we performed an arthroscopically assisted arthrodesis of the ankle. The patients' ages ranged from 31 to 69 years. The male:female ratio. Sixteen patients had posttraumatic degenerative joint disease, three patients suffered from a previous infection, four patients had rheumatoid arthritis, and three patients had an osteochondritis dissecans in their past history. The time taken for surgery ranged from 65 to 135 min. Compared with open procedures we documented less postoperative swelling and minor use of analgesics. Time of follow-up was a minimum of 6 months and a maximum of 75 months. In 22 patients we found solid fusion at the time of followup. Fusion was accomplished by 2 months postoperatively in four patients, by 3 months in nine patients, by 4 months in another six patients, and by 6 months in 3 patients. Three patients did not evidence any bony fusion, but they were free of pain. In one patient an open revision was necessary. According to our experience, we recommend arthroscopically assisted arthrodesis of the ankle in patients with degenerative joint disease without rotational or varus/valgus malalignment, severe bone defects or neuropathic disease.
