Retaining bi-cruciate ligaments in knee prostheses (FOX study)
In this study, we compare the movement of a knee prosthesis in which both cruciate ligaments are retained with a prosthesis in which only the posterior cruciate ligament is retained. Additionally, the stability of both prostheses is investigated to evaluate the fixation of the prostheses into the bone.
A total of 40 patients, who were on the waiting list for primary total knee arthroplasty, participate in this randomized study. Twenty patients received a knee prosthesis in which both cruciate ligaments were spared, and twenty patients received a knee prosthesis in which only the posterior cruciate ligament was spared. These patients are followed for two years to evaluate, among other things, the movement of the knee (femoral rollback), the stability of the prostheses (movement of the prosthesis with respect to the bone) and patient satisfaction. This study started in 2014 and will be finished in 2019.
