[Articles] Patellar resurfacing in total knee replacement: 20-year clinical and economic results of a large multicentre, randomised controlled trial in the UK (opens in new tab)

There was no significant difference in primary outcome (OKS) or other clinical endpoints. However, as clinical differences tend to support patellar resurfacing, the resurfacing group had significantly higher QALYs. There was no difference in costs over the 20-year period, and patellar resurfacing had a 99% probability of being cost-effective at any threshold above £10 000 per QALY gained. The evidence is therefore weighted towards resurfacing being the approach of first choice.
