Abstract

Introduction

In revision knee arthroplasty, rotating hinge implants (RHK) have been considered to result in higher complication rates and lower survivorship when compared to constrained condylar implants (CCK). The aims of this study were to compare patient reported outcome measures (PROMs), complication rates and survivorship of RHK and CCK used in revision arthroplasty at a single, high volume elective orthopaedic centre with previously validated bespoke database.

Methodology

One hundred and eight patients who underwent revision knee arthroplasty with either CCK or RHK and matched our inclusion criteria were identified. EQ5D, Health State and Oxford Knee Scores were collected pre-operatively and at 1 year post-operatively. Complication data was collected at 6 weeks, 6 months, 1 year and 2 years post-operatively. NJR data was interrogated, in addition to our own database, to investigate implant survival.

Purpose

To determine the effect that Titanium Nitride (TiN) coatings have on wear rates of ultra high molecular weight polyethylene (UHMWPE)

Background

Ceramic coatings have been shown to confer advantageous countersurface scratch resistance in knee arthroplasty. This may reduce UHMWPE wear rates and revision rates. Dermal hypersensitivity is a common problem with metals; TiN, a ceramic surface, has been used to prevent it. There is little data in the literature regarding the effect of TiN on UHMWPE.
