Medial compartment osteoarthritis of the knee: a review of surgical options

Daniel J. McCormack, Darren Puttock, and Steven P. Godsiff
  • Osteoarthritis of the medial compartment, where the lateral compartment and patella-femoral joint are relatively spared, is a common orthopaedic presentation.

  • Most frequently, the treatment of choice would be a total knee replacement, which involves removing healthy joint surfaces in such patients.

  • Arthroscopic debridement in the osteoarthritic knee has fallen out of favour due to poor clinical results.

  • A trend has developed towards less invasive surgery with uni-compartmental knee replacement (UKR) and high tibial osteotomy (HTO) gaining increasing popularity.

  • Surgeons differ in their relative indications and contraindications to performing these procedures.

  • Total knee replacement (TKR) continues to have the lowest overall revision rate of the available options.

  • Growing evidence demonstrates more favourable patient-reported outcome measures in UKR and HTO patients, compared to TKR.

  • Knee joint distraction (KJD) has been demonstrated as an alternative method of treatment in such patients.
