CLINICAL OUTCOMES OF COMPUTER-ASSISTED TOTAL KNEE ARTHROPLASTY USING PINLESS NAVIGATION

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). Results 100 patients were recruited in both arms of the study. Patients in the pinless navigation arm underwent a shorter duration of surgery compared to those in the standard CAS arm with 72±13 min and 83±11 min respectively (p Conclusion Pinless navigation in TKA with CAS provides improvement in clinical outcomes that are similar to patients who underwent standard CAS with a shorter duration of surgery.
