Primary Outcome Measures:
  • Range of Motion [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    The primary outcome is change in ankle range of motion

Secondary Outcome Measures:
  • Pain [ Time Frame: 4 months ] [ Designated as safety issue: No ]
    The secondary outcome will be change in pain scale rating as reported by patient
