Correction osteotomy surgery for knee osteoarthritis improves function and reduces pain. However, evidence does not yet support its superiority over conservative treatments or specific surgical techniques.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Rheumatology

Background:

  • Unicompartmental knee osteoarthritis can be managed with correction osteotomy to shift load-bearing to healthy compartments.
  • Successful outcomes depend on patient selection, osteoarthritis stage, and achieving adequate surgical correction.

Purpose of the Study:

  • To evaluate the effectiveness and safety of osteotomy for treating knee osteoarthritis.

Main Methods:

  • A systematic review of randomized and controlled clinical trials comparing high tibial osteotomy (HTO) or distal femoral osteotomy for unicompartmental knee osteoarthritis.
  • Searches included Cochrane CENTRAL, MEDLINE, and EMBASE up to May 2007.

Main Results:

  • Thirteen studies (693 participants) focused on valgus HTO for medial compartment osteoarthritis.

  • Most studies indicated patient improvement (pain reduction, better function) post-osteotomy.
  • No significant differences were found compared to other operative treatments; overall study quality was low.

    • Conclusions:

    • Valgus HTO demonstrates 'silver' level evidence for improving knee function and reducing pain.
    • Evidence is insufficient to compare osteotomy with conservative treatment or to conclude on specific surgical technique effectiveness.
