Primary Outcome Measures:
  • Delayed union or nonunion of the distal femur [ Time Frame: 12 months post operative ] [ Designated as safety issue: No ]
    Determined via radiographic analysis

Secondary Outcome Measures:
  • Time to clinical healing [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    assessed by weight-bearing ability and pain

  • Function as assessed by patient [ Time Frame: 6 months, 12 months ] [ Designated as safety issue: No ]
    Assessed using LEM, SMFA, and SF-36 questionnaires

  • Frequency of adverse events [ Time Frame: 12 months ] [ Designated as safety issue: Yes ]
  • Range of motion [ Time Frame: Post-op, 6 weeks, 3 months, 6 months, 12 months ] [ Designated as safety issue: No ]
  • Gait analysis [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 150
