Patient’s Perception in Bicruciate-Retaining Total #KneeArthroplasty by Florian Baumann in BJSTR

Abstract

In treatment of advanced osteoarthritis, total knee arthroplasty (TKA) with the sacrifice of the #anteriorcruciateligament (ACL) is the standard treatment. There is high proportion of patients who report residual #knee symptoms after TKA without any identifiable objective clinical or radiological reasons. In regards to cruciate-retaining knee arthroplasty in the last decade, knee surgeons have mainly focused on the posterior cruciate ligament [1-4]. However, anatomic studies have shown cruciate ligaments; especially anterior cruciate ligament contains a considerable number of proprioceptive nerve cells. Sacrifice of the ACL can also be accompanied with #abnormalkinematics resulting in functional limitations and a reduced balance [3,4]. Reduced balance capacity can cause various problems in activity of daily living (ADL). Balance problems due to limitations in #proprioception after TKA can cause frequent falls. Besides this, reduced balance after the arthroplasty can lead to a situation where patient senses the joint as a foreign body which can be associated with non-specific pain and can cause functional deficit [1,4-6]. First generation bicruciateretaining total knee arthroplasty (BCR-TKA) was developed in the 1960s which aimed for a natural knee joint movement. #Bicruciateretainingimplants have shown a more #physiologicanteriorfemorotibial contact point and a greater posterior translation in motion compared to ACL-sacrificing #implants Cloutier et al.[1,3,6-10].
