Comparing two different designs of total knee arthroplasty in 120 patients: 60 patients receive the prosthesis in which the posterior cruciate ligament is spared and 60 patients receive the prosthesis in which the ligament is sacrificed.

Design outcomes

Primary

MeasureTime frame
To examine whether there is a difference in patients perceived outcome between a posterior cruciate retaining total knee arthroplasty compared with a posterior stabilized total knee arthroplasty.—

Secondary

MeasureTime frame
To determine whether there is a difference in range of motion between a posterior cruciate retaining total knee arthroplasty compared with a posterior stabilized total knee arthroplasty. Additionally, to determine whether there is a difference in Knee Score (physician-based outcome score), health-related quality of life, gait parameters and femoral roll back.—
