Procedure: Implantation of a Total Knee Arthroplasty

Interventions

In all patients a cemented, unconstrained, cruciate-retaining TKA with a rotating platform (ScorpioTM PCS, Stryker Orthopaedics, Mahwah, NJ) was implanted. No patellar resurfacing was performed. A medial parapatellar approach with a femur-first preparation was done in all cases. The Stryker Navigation System, Knee Navigation Software V3.1 (Stryker Orthopaedics, Mahwah, NJ) was used for computer-assisted implantation. The conventional implantation was performed with femoral intramedullary and tibial extramedullary standard alignment guides.
