In plain words

What the trial is, and whether it could suit you

The primary purpose of this study is to compare reoperation rates for rotating hinge knee implants versus condylar constrained knee implants when used in revision total knee arthroplasty. The secondary purposes are to compare patient satisfaction, loosening rates and clinical outcomes for RHK implants compared to CCK implants in rTKA. Additionally, knee range of motion and stability will be assessed and compared at all follow-up time points. We hypothesize that RHK implants provide patients undergoing rTKA with similar reoperation rates to those of patients who receive a CCK implant. The investigators hypothesize that patients who receive an RHK implant will have similar loosening rates and clinical outcomes compared to patients who receive a CCK implant. Lastly, knee stability and patient satisfaction may improve with the use of a rotating hinge device.
