Interventions

Electromagnetically navigated total knee arthroplastydevice

The navigated group had surgery using the iNav portable EM navigation system (Zimmer GmbH, Winterthur, Switzerland and Medtronic, Minneapolis, MN, USA) and the definitive implant used was NexGen LPS implant (Zimmer Inc, Warsaw, IN, USA), a fixed-bearing bicruciate-sacrificing total condylar implant using traditional instrumentation with no patellar resurfacing

Conventional total knee arthroplastydevice

The conventional group received surgery using conventional instrumentation and jigs from the implant manufacturer (Zimmer Inc, Warsaw, IN, USA) and the definitive implant used was NexGen LPS implant (Zimmer Inc, Warsaw, IN, USA), a fixed-bearing bicruciate-sacrificing total condylar implant using traditional instrumentation with no patellar resurfacing
