The bicruciate-retaining TKA: Two is better than one

Bicruciate-retaining total knee arthroplasty (TKA), which retains both the anterior and posterior cruciate ligaments, serves as an alternative to the traditional TKA procedure. This article highlights the relevant clinical investigations using the bicruciate-retaining TKA and their findings. Despite the difficulty of ensuring the structural integrity of the prosthesis, the bicruciate-retaining TKA can yield improved patient outcomes such as range of motion, kinematics, and even the survivorship of the implant. When possible, the bicruciate-retaining TKA can and should be considered as a viable option to treat end-stage arthritis of the knee.
