Joint distraction and reconstruction using the Ilizarov fixator improved mobility in complex knee contractures. While range of motion didn

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Complex knee contractures significantly impair mobility and function.
  • Previous treatments often yield suboptimal outcomes for severe cases.

Purpose of the Study:

  • To evaluate the efficacy of joint distraction and reconstruction for complex knee contractures.
  • To assess functional improvements and recurrence rates following surgical intervention.

Main Methods:

  • Retrospective review of 6 patients (9 knees) treated with Ilizarov fixator.
  • Included joint distraction, reconstruction, and alignment of extensor mechanism or mechanical axis.
  • Average follow-up of 53 months.

Main Results:

  • Mean total arc of movement remained unchanged but became more functional.

  • Significant reduction in flexion contracture (mean 100 degrees) with improved flexion.
  • All patients achieved ambulation; 4 had no recurrence, 2 experienced rebound.
  • 4 patients reported satisfaction with surgical outcomes.

    • Conclusions:

    • Joint distraction and reconstruction with the Ilizarov fixator can improve functional mobility in complex knee contractures.
    • Addressing extensor mechanism and mechanical axis realignment is crucial.
    • Preoperative planning and staged procedures may minimize recurrence risk.
