Many prosthetic design changes have been introduced in attempt to improve outcomes following TKA; however there is no consensus as to whether these changes confer benefits to patients. This study aimed to assess whether patients treated with a modern implant design had an enhanced patient outcome compared to a traditional model in a double blind randomised controlled trial. 212 consecutive patients were prospectively randomised to receive either a modern (Triathlon) or a traditional (Kinemax) TKA (both Stryker Orthopaedics). 6 surgeons at a single unit performed all procedures in a standardised manner. A single researcher, blinded to implant allocation, performed all assessments. Patients were assessed pre-operatively, and at 6, 26, 52 weeks post-surgery with the Oxford Knee Score (OKS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, goniometry, timed functional assessment, lower limb power (Leg Extensor Power Rig) and pain numerical rating scales (NRS). Change in scores and between group differences were assessed with Two-Way Repeated Measures ANOVAs.Introduction
Methods
To investigate the incidence, types and trends in diagnosis of venous thromboembolic events (VTE) in patients undergoing total knee arthroplasty (TKA) over a ten-year period. Data from 5100 consecutive TKAs performed in our unit between April 1996 and March 2006 were prospectively collected by the Scottish Arthroplasty Project (SAP). This database contains data on 100% of arthroplasty cases in Scotland. We retrospectively reviewed casenotes of these patients to identify thromboprophylaxis given, the diagnosis of VTE, treatment and adverse outcomes.Aim
