The objective of this study was to determine the in vivo kinematics during weight-bearing and non-weight-bearing activities for subjects with a unicompartmental knee arthroplasty (UKA) designed for high flexion and implanted with minimally invasive techniques. A total of 30 UKAs implanted in 18 patients were analyzed. All patients were implanted with a(More)
UNLABELLED Patterns of motion in the native knee show substantial variability. Guided motion prosthetic designs offer stability but may limit natural variability. To assess these limits, we therefore determined the in vivo kinematic patterns for patients having a cruciate-substituting TKA of one design and determined the intersurgeon variability associated(More)
This study examines the effect of component downsizing in a modern total knee arthroplasty (TKA) system on the laxity envelope of the knee throughout flexion. A robotic testing system was utilized to measure laxity envelopes in the implanted knee by in the anterior–posterior (AP), medial–lateral (ML), internal–external (IE) and varus–valgus (VV) directions.(More)
