Purpose

This study aims to evaluate the two-year post-operative clinical outcomes of patients undergoing total knee arthroplasty (TKA) with computer-assisted surgery (CAS) using a pinless navigation system (BrainLAB® VectorVision® Knee 2.5 Navigation System) versus standard CAS.

Methods

We analysed prospectively collected data from patients who underwent TKA with CAS from November 2008 to October 2012 over a two year follow-up period by a single senior surgeon. Primary outcome measures include Short-Form 36 (SF-36), Oxford Knee (OKS) as well as Knee Society Scores (KSS).

Purpose

The purpose of this study was to compare joint line changes between posterior-stabilized (PS) and cruciate-retaining (CR) computer navigated total knee arthroplasties (TKA) and to evaluate the impact on functional outcome.

Background

Restoration of the native joint line has been a common goal in all TKA designs. Computer-navigated TKA in increasingly being favoured by many surgeons, due to increased precision and lesser complications. Few studies have reported the effect of computer navigated TKA on joint line restoration. It remains to be seen if the greater precision offered by computer-navigated TKA in restoration of joint line translates to improvement in functional outcome.
