Bicruciate-Retaining TKA: How to Achieve Near-Normal Kinematics

Total knee arthroplasty (TKA) is widely accepted as a successful treatment for end-stage knee osteoarthritis (OA), relieving pain and improving function, with long-lasting implants. The success of TKR is reflected in the increasing demand for the procedure. In the UK approximately 85,000 primary TKRs were performed in 2015 and more than 620,000 in the USA in 2009 [1, 2]. These numbers are on the rise as shown by temporal trends in multiple countries, with US TKR numbers projected to rise to 3.48 million by 2030 alone [3–6].
