The combination of partial knee arthroplasties in knee osteoarthritis with an intact anterior cruciate ligament- afuture model?

Abstract

Preserving both cruciate ligaments in knee prosthetics enables approximately physiological joint kinematics. In this way, faster rehabilitation and ahigher return-to-sports rate can be achieved. Accordingly, there are considerations to preserve both cruciate ligaments by combining two partial prostheses in the case of symptomatic bicompartmental (BiCom) knee osteoarthritis. This article summarizes the literature on BiCom arthroplasty and describes our own experiences from 54consecutive cases with robotic-assisted technology. According to current data, BiCom arthroplasty shows good clinical results, without being able to demonstrate aclear advantage over conventional TKA. The revision risk is slightly increased in the short-term interval, which could be positively addressed with robotic-assistance. The disadvantages are the increased implant costs and the risk of subsequent osteoarthritis. Accordingly, patients who may potentially take advantage of this treatment must be critically selected.
