The study will be conducted using two groups. The first group will be a retrospective review of charts of 35 patients who received a total ankle replacement porous prosthesis by an orthopedic surgeon at the University of Oklahoma Health Sciences Center. This group was received a delayed 6 week post-operative weight-bearing protocol.~The second group will be prospective and include patients who will receive the same total ankle replacement porous prosthesis but will be assigned to early 2 weeks post-operative weight-bearing protocol.The retrospective and prospective groups will be age and gender matched. A Wright Medical Infinity Total Ankle Replacement System will be used for both groups.~Both groups will be assessed at 1 year and 2 years post-operative. This assessment will take place during the post-operative care period and will be conducted as part of their post-operative care by the operating physician.
The Investigators hypothesize that an early 2 week post-operative protocol will have no difference in the successful osseointegration and stability of the total ankle replacement as compared to a delayed 6 week post-operative protocol. The importance of the research is to allow patients who receive a total ankle replacement to bear weight 4 weeks earlier than the current protocol with no negative effect on the osseointegration and stability of the ankle replacement.
