Summary

Knee joint fusion using an anterior unilateral external fixator (monofixator) effectively treats posttraumatic and infectious destruction. This method achieves stable fusion, eradicates infection, and offers patient comfort, making it a reliable surgical option.

Area of Science:

  • Orthopedic Surgery
  • Trauma Surgery
  • Infectious Disease Management

Background:

  • Operative knee joint fusion is crucial for managing severe knee destruction.
  • External fixation, particularly unilateral external fixators, offers advantages in stability and patient comfort.
  • The monofixator is the preferred method at our institution for knee arthrodesis.

Purpose of the Study:

  • To evaluate the efficacy of knee arthrodesis using an anteriorly placed unilateral external fixator.
  • To assess outcomes in patients with posttraumatic and infectious knee destruction treated with this technique.

Main Methods:

  • Retrospective review of 19 knee arthrodesis procedures performed between 1985 and 1994.
  • Utilized an anteriorly placed unilateral external fixator (monofixator).

  • Indications included post-osteosynthesis infection, posttraumatic arthrosis with infection, flexion ankylosis, and osteoarthritis with empyema.

    • Main Results:

    • Successful stable fusion of the knee joint was achieved in all cases.
    • Complete eradication of infection was confirmed.
    • The mean fixation duration was 22 weeks, with no premature fixator removals required.

    Conclusions:

    • Anterior unilateral external fixation (monofixator) is a safe and effective technique for knee joint arthrodesis.
    • It provides stable fusion and infection control for complex knee destruction.
    • The procedure demonstrates good patient outcomes and comfort.
