The indications for total ankle replacement srthroplasty are controversial. We reported a retrospective study of six total ankle arthroplasties performed between Oct. 1988 and Oct. 1990. These have been reviewed clinically after an average follow-up period of two years. In our four New Jersey type and two Odland type, one ankle was rated excellent and five, good, The relief of pain was gratifying in all of the patients, only two patients having residual slight pain. The average gain in the range of motion was 25 degrees of planter flexion. No patient had infection or loosening that required reoperation, although 2mm width of radiolucent lines were seen in one ankle.
