TL;DR: Data from this multicenter study are remarkably similar to previous fluoroscopy data from a single surgeon series, showing a lack of customary posterior femoral rollback in both posterior cruciate retaining designs and conversely showing an average anterior femoral translation with knee flexion.

TL;DR: In this paper, the authors used fluoroscopy and computed tomography to accurately determine the three-dimensional, in vivo, weightbearing kinematics of five normal knees, including femur and tibia.

TL;DR: A summation analysis of more than 70 individual kinematic studies involving normal knees and 33 different designs of total knee arthroplasty was done with the objective of analyzing implant design variables that affect knee kinematics, finding that anterior femoral translation during deep flexion was most commonly observed in PCL-retaining TKA.

TL;DR: The abnormal anterior femoral translation observed in the posterior cruciate retaining knees may be a factor in the premature polyethylene wear seen in retrieval studies.

TL;DR: A considerable difference was found between the center of rotation locations of the normal and ACLD subjects, with ACLDSubjects exhibiting substantially higher variance in kinematic patterns.
