Overview
Brief Summary
This is a research study which is being done to determine the outcomes following Agility LP ankle replacement. This implant was approved by the FDA in 2007 and has been used since then with good early results. You are being asked to volunteer for this study because you have undergone Total Ankle Arthroplasty with Agility LP prosthesis. The purpose of the study is to compare the range of motion, level of pain and function during daily living prior to and after your ankle surgery.

Outcomes
Primary Outcomes
Assessment of Functional Outcomes Following Agility LP Ankle Replacement
Time Frame: A Minimum of 2 Years Post Index Procedure
Range of Motion - Combined total of dorsiflexion and plantarflexion. Full range of motion is described as 30 degrees or more. Partial limitation is described as 29 to 15 degrees. Range of motion that is less than 15 degrees is described as severely limited.
Secondary Outcomes
- Evaluation of Complication and Reoperation Rates(A Minimum of 2 Years Post Index Procedure)
- Radiographic Predictors of Implant Failures and Poor Outcomes(A Minimum of 2 Years Post Index Procedure)
