Overview
Brief Summary
Randomized study comparing surgical and economic parameter of Total Knee Arthroplasty performed using two different specific surgical techniques.
Detailed Description
Randomized 1: ratio study comparing Medacta MyKnee surgical technique using Efficiency single use instruments versus Stryker Navigation surgical techniques performed with conventional instruments. MyKnee surgical technique patients will receive a CT scan of the surgical knee which enables custom manufacturing of the MyKnee cutting blocks. Stryker Navigational surgical technique patients will not require a CT scan. Both groups of patients will undergo total knee arthroplasty.
