Cost-effectiveness of unicompartmental compared with total knee replacement: a population-based study using data from the National Joint Registry for England and Wales.

ABSTRACT:

Objectives

To assess the value for money of unicompartmental knee replacement (UKR) compared with total knee replacement (TKR).

Design

A lifetime Markov model provided the framework for the analysis.

Setting

Data from the National Joint Registry (NJR) for England and Wales primarily informed the analysis.

Participants

Propensity score matched patients in the NJR who received either a UKR or TKR.

Interventions

UKR is a less invasive alternative to TKR, where only the compartment affected by osteoarthritis is replaced.

Primary outcome measures

Incremental quality-adjusted life years (QALYs) and healthcare system costs.

Results

The provision of UKR is expected to lead to a gain in QALYs compared with TKR for all age and gender subgroups (male:
