Summary

Total hip replacement (THR) and total knee replacement (TKR) are cost-effective for osteoarthritis (OA) management. Exercise, bracing, and supplements show value, while ineffective treatments should be reconsidered for resource allocation.

Area of Science:

  • Orthopedics
  • Health Economics
  • Clinical Trial Analysis

Background:

  • Osteoarthritis (OA) management comparisons are hindered by varied study quality and outcome measures.
  • A common metric is needed to compare disparate OA interventions effectively.

Purpose of the Study:

  • To translate published trial outcomes into a health-related quality-of-life (utility) scale.
  • To compare the cost-effectiveness of various osteoarthritis interventions using a unified metric.

Main Methods:

  • Utilized the "transfer to utility" technique to standardize outcome reporting.
  • Calculated cost per quality-adjusted life-year (QALY) for different OA treatments.

Main Results:

  • Total hip replacement (THR) and total knee replacement (TKR) were most effective and cost-effective (approx. $7,500/QALY for THR, $10,000/QALY for TKR).

  • Exercise, strength training, knee bracing, capsaicin, and glucosamine sulfate were also highly cost-effective (<$10,000/QALY).
  • Ineffective interventions (e.g., arthroscopy) and those lacking efficacy data (e.g., prevention programs) require resource reallocation and further research.

    • Conclusions:

    • The Health-sector Wide model provides an evidence-based approach to prioritize OA interventions.
    • Resource allocation can be optimized by expanding effective treatments and contracting or researching less effective ones to reduce OA burden.
