Total Ankle System

When it comes to ankle pain and limited mobility due to ankle joints damaged by severe rheumatoid, post-traumatic, or degenerative arthritis. Dr. Schmidt combines the revolutionary design of Wright Medical’s INBONE II® Total Ankle prosthesis with the PROPHECY® pre-operative navigation system.


Since its inception in 2005, the INBONE II® Total Ankle System from Wright Medical has continued to be the most distinctive and innovative total ankle replacement system on the market.  It is the first total ankle system that provides intramedullary instrumentation (utilizing the vertical axis of a patient’s shinbone) for accurate component positioning and the first ankle prosthesis with modular components for patient specific needs.

When it comes to joint implants, one size does not fit all. The modular design of the INBONE II® Total Ankle allows Dr. Schmidt to select the appropriate components based on patient size and bone structure. This results in a more precise fit and less-invasive procedure.

The INBONE II® Total Ankle is intended to give a patient limited ability by reducing pain, restoring alignment and replacing the flexion and extension movement in the ankle joint.


The INBONE II® Total Ankle is additionally indicated for patients with a failed previous ankle surgery.


Use of the PROPHECY® Preoperative Navigation Guides have ushered in a new era of total ankle replacement. Through the combination of computer imaging and the patient’s own CT scan, a customized plan can be developed for their own unique anatomy, in advance of ankle replacement surgery. This reduces surgical steps, operating time, radiation exposure from x-rays during surgery while increasing patient specific anatomic alignment with precision fixation of the implants.

Why Total Ankle Replacement?

Ankle arthritis has several accepted operative and non-operative treatment options. Operative treatment is generally considered for patients with persistent symptoms that fail to respond to appropriate and comprehensive non-operative treatment measures. Surgical options include joint debridement, distraction arthroplasty, osteotomy, arthrodesis, and total ankle arthroplasty (joint replacement). Traditionally, arthrodesis (fusing the ankle joint together) was the favored treatment for end stage ankle arthritis. However, the restricted motion following arthrodesis increases the stresses on the surrounding joints leading to further arthritic changes. Total ankle arthroplasty preserves motion and may be protective against further degeneration while providing equivalent pain relief.

Total ankle replacement surgery is a safe and effective treatment option for select patients with ankle arthritis. In many patients total ankle replacement surgery substantially improves function, reduces pain, and allows for an improved quality of life. Patient mobility and quality of life factors contribute to longer independent living and to controlling overall health care costs.
