Is the Posterior Cruciate Ligament Necessary in Cruciate-Substituting Total Knee Arthroplasty? A Cadaveric Comparison of Knee Kinematics With or Without the PCL Versus the Native Knee.

BACKGROUND: This study sought to determine knee kinematics after cruciate-substituting (CS) total knee arthroplasty (TKA) using an insert with or without the posterior cruciate ligament (PCL) in the same-specimen fresh-frozen cadavers using a within-…
