England has a significant underprovision of total knee replacements (TKR). The estimated annual need for TKR is 55,800, far exceeding the 29,300 currently provided.

Area of Science:

  • Orthopedics
  • Public Health
  • Epidemiology

Background:

  • Osteoarthritis significantly impacts quality of life and mobility.
  • Total knee replacement (TKR) is a common surgical intervention for severe knee osteoarthritis.
  • Assessing the population requirement for TKR is crucial for healthcare planning.

Purpose of the Study:

  • To determine the population requirement for total knee replacement (TKR) in England.
  • To compare the demand for TKR with the current provision of the procedure.

Main Methods:

  • A population-based study utilized an age/sex-stratified random sample of 28,080 individuals aged 35 and over.
  • Statistical modeling estimated incident disease from prevalence data.
  • The New Zealand priority criteria for major joint replacement were applied for case selection.

Main Results:

  • The estimated annual requirement for TKRs in England was 55,800, significantly higher than the observed provision of 29,300.
  • Patients with knee disease were less likely to be referred for specialist care or placed on waiting lists compared to those with hip disease.
  • Considering patient willingness to undergo surgery reduced the estimated TKR requirement.

Conclusions:

  • There is evidence of underprovision of total knee replacement (TKR) in England.
  • Discrepancies in perceived disease severity and surgical outcomes between patients, general practitioners, and specialists may contribute to underprovision.
  • Further investigation into patient and clinician perspectives is warranted to address the TKR gap.
