Optimising outcomes in lateral unicompartmental knee arthroplasty: Analysing 25 years of registry data.

ABSTRACT:

Purpose

Limited data and experience surround lateral unicompartmental knee arthroplasty (UKA), contributing to uncertainty regarding its broader application in clinical practice. To understand how to optimise lateral UKA outcomes, this study aimed to evaluate the implant survival of lateral UKA and compare it to total knee arthroplasty (TKA) using registry data.

Methods

Data were obtained from the Danish Knee Arthroplasty Registry, the Danish National Patient Registry and the Danish Civil Registration System. Between 1997 and 2022, all primary lateral UKAs (n = 538) and primary TKAs performed on valgus-aligned knees were included. Propensity score matching (1:4) matched patients by age, sex, weight, Charlson comorbidity index, year of surgery and hospital type. Survival anal
