Area of Science:

  • Orthopedic Surgery
  • Biomaterials Science
  • Clinical Outcomes Research

Context:

  • Aseptic loosening of the tibial component is a common complication following knee joint alloplasty.
  • Revision surgery is often required to address this complication, aiming to restore function and alleviate pain.
  • Evaluating the efficacy of revision procedures is crucial for improving patient management and long-term joint health.

Purpose:

  • To assess the clinical outcomes of revision knee joint alloplasties specifically for aseptic loosening of the tibial component.
  • To evaluate the effectiveness of surgical intervention in terms of bone healing and functional recovery using modified HSS knee rating scale.
  • To provide insights into the long-term results and patient-reported outcomes following revision knee arthroplasty.

Summary:

Related Experiment Videos

  • The study analyzed 12 patients (10 female, 2 male, aged 68-73) who underwent revision knee surgery between 2000-2003 for aseptic tibial component loosening.
  • Follow-up ranged from 6 months to 2 years. Outcomes were assessed between 20-24 months post-revision using bone healing time criteria and a modified Hospital for Special Surgery (HSS) knee rating scale.
  • Results showed 9 excellent and 1 good outcome based on healing time, and 5 excellent, 1 good, 3 fair, and 1 poor outcome based on the HSS scale.

Impact:

  • This research contributes to understanding the effectiveness of revision knee arthroplasty for aseptic loosening, informing surgical decision-making.
  • The findings highlight the potential for successful functional restoration and pain relief in patients undergoing revision surgery.
  • Provides valuable data for orthopedic surgeons managing complications of primary knee replacements and planning revision strategies.
