The introduction of additional bicruciate-retaining systems can trace their development back to these early designs. Pritchett JW. In bicruciate-retaining designs, both the anterior and posterior cruciate ligaments are kept. It's called the bicruciate-retaining design because you get to keep both ligaments. From January 1989 to September 1992, I performed 639 total knee replacements in 537 patients. The polycentric knee and the duocondylar spared the cruciate ligaments but led to early failures and loss of fixation.
