Abstract

Introduction

With respect to survivorship following total knee arthroplasty (TKA), joint registries consistently demonstrate higher revision rates for both sexes in those less than 55 years. The current study analyses the survivorship of 500 cementless TKAs performed in this age group in a high-volume primary joint unit where cementless TKA has traditionally been used for the majority of patients.

Methods

This was a retrospective review of 500 consecutive TKAs performed in patients under the age of 55 between March 1994 and April 2017. The primary outcome measure for the study was all-cause revision. Secondary outcome measures included clinical, functional and radiological outcomes.

Results

The all-cause revision rate was 1.6% (n=8) at a median of 55.7 months. Four were revised for infection, 2 for stiffness, 1 for aseptic loosening of the tibial component and 1 patella was resurfaced for anterior knee pain. The aseptic revision rate was 0.8% (n=4). Twenty-seven (5.4%) patients underwent a manipulation under anaesthetic (MUA). Including those who underwent MUA, 6.8% (n=34) underwent other non-revision procedures.

Conclusion

Survivorship in our unit in this young patient cohort was excellent with an aseptic revision rate of 0.8% at 59.7 months using a fully cementless construct. The MUA rate was higher than expected.
