Sacrifice of the posterior cruciate ligament (PCL) in revision total knee replacement (TKR) is common, aiding in exposure, restoration of the flexion space, obtaining postoperative stability, and improving the clinical outcomes. Several PCL substituting implants are available including deep-dished, post-and-cam, varus/valgus constrained, and hinge implants. Use of the least constrained implant possible has been advised in the literature.1-5
