A contemporary bicruciate total knee arthroplasty

Bicruciate retaining total knee arthroplasty dates back to the 1970s. The polycentric knee and the duocondylar spared the cruciate ligaments but led to early failures and loss of fixation. Designing surgeons excised the cruciates in order to facilitate the surgical procedure and improve the clinical results. Ultimately, the posterior cruciate sparing and substituting designs dominated the market. Most total knees are now anterior cruciate ligament deficient and 15-20% of patients are not satisfied with their surgical result. Bicruciate sparing total knee arthroplasties are now returning to the market and may afford improved results and satisfaction.
