  Purpose

The purpose of this study is to determine any functional outcome differences in patients who have undergone surgical treatment for ankle osteoarthritis using surveys, step counts, and laboratory gait analysis.

This study is closed to recruiting new subjects but remains open for continued follow-up procedures.

Primary Outcome Measures:
  • Daily activity level measured by the Step Activity Monitor [ Time Frame: Over the course of 3 years ] [ Designated as safety issue: No ]
    Daily step counts recorded on StepWatch Activity Monitors (SAMs) Patient reported data on pain, function, disability, and satisfaction with surgery using the MFA, SF-36, and pain questionnaire.


Secondary Outcome Measures:
  • Gait analysis [ Time Frame: Over the course of three years ] [ Designated as safety issue: No ]

Estimated Study Completion Date: September 2015
Estimated Primary Completion Date: June 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Group 1
Subjects undergoing ankle arthrodesis (fusion) for treatment of ankle arthritis
 Procedure: Gait analysis
Subjects will come into motion analysis laboratory at the VA Puget Sound Health Care System. A standard set of body measurements will be taken using calipers, a measuring tape, and a scale (for example height, weight, leg length, foot length, etc). We will then attach small reflective markers to your body using double-sided tape and ask you to walk several times as the motion of each marker is recorded by infrared cameras.
Group 2
Subjects undergoing ankle arthroplasty (replacement) for treatment of ankle arthritis
 Procedure: Gait analysis
Subjects will come into motion analysis laboratory at the VA Puget Sound Health Care System. A standard set of body measurements will be taken using calipers, a measuring tape, and a scale (for example height, weight, leg length, foot length, etc). We will then attach small reflective markers to your body using double-sided tape and ask you to walk several times as the motion of each marker is recorded by infrared cameras.
