Despite the well-established success of total knee arthroplasty (TKA), iatrogenic ligamentous and soft tissue injuries are infrequent, but potential complications that can have devastating impact on clinical outcomes. These injuries are often related to technical errors and excessive soft tissue manipulation, particularly during bony resections. Recently, robotic-arm assisted TKA was introduced and demonstrated promising results with potential technical advantages over manual surgery in implant positioning and mechanical accuracy. Furthermore, soft tissue protection is an additional potential advantage offered by these systems that can reduce inadvertent human technical errors encountered during standard manual resections. Therefore, due to the relative paucity of literature, we attempted to answer the following questions: 1) does robotic-arm assisted TKA offer a technical advantage that allows enhanced soft tissue protection? 2) What is the available evidence about soft tissue protection? Recently introduced models of robotic-arm assisted TKA systems with advanced technology showed promising clinical outcomes and soft tissue protection in the short- and mid-term follow-up with results comparable or superior to manual TKA. In this review, we attempted to explore this dimension of robotics in TKA and investigate the soft tissue related complications currently reported in the literature.
