“…The predicted in vivo knee joint forces and motions can readily be used to predict the surface wear of the TKR using the methodology already established [1]. All previous wear predictions have used fixed load/kinematics for the wear simulation of TKR, and not considered the effect of the change of kinematics/load due to tibial insert geometry variation caused by wear [30][31][32][33]. The use of fixed load/motion in the wear simulation means that the change of these input conditions, which affects the multi-directional cross-shear motion [34,35], has not been considered.…”

A novel wear prediction framework was developed by coupling a patient-specific lower extremity musculoskeletal multibody dynamics model with the finite element contact mechanics and wear model of total knee replacement. The tibiofemoral contact forces and kinematics were influenced by articular surface wear, and in turn, the variations from the knee dynamics resulted in increases in the volumetric wear of 404.41 mm 3 after 30 million cycle simulation from 380.86 mm 3 from the traditional wear prediction using fixed load/motions. The developed patient-specific wear prediction framework provided a reliable virtual platform for investigating articular surface wear of total knee replacements.

“…The tibia is fixed in the region corresponding to the ankle [11,18,24,41]. Loads and kinematics were applied to the femur to dynamically replicate walking and squatting motor [19,22,[34][35][36]. In particular, for the simulated gait task, the boundary conditions were defined by the ISO-14243-1 [22,35] in terms of flexion extension, axial force, anteroposterior translation and internal-external rotation.…”

“…In this study, orthopaedist present during experimental session, analysed patients radiography to exclude possible recognisable anomalies. However, a measure of arthroplasty positioning was not provided even if Authors know that an arthroplasty misalignment can produce alterations on dynamics and kinematics both for TKA 8,14,28,29 and for UKA 30 .…”

SummaryBackground: In this paper, squat named by Authors unconstrained because performed without constrains related to feet position, speed, knee maximum angle to be reached, was tested as motor task revealing differences in functional performance after knee arthroplasty. It involves large joints ranges of motion, does not compromise joint safety and requires accurate control strategies to maintain balance. Methods: Motion capture techniques were used to study squat on a healthy control group (CTR) and on three groups, each characterised by a specific knee arthroplasty design: a Total Knee Arthroplasty (TKA), a Mobile Bearing and a Fixed Bearing Unicompartmental Knee Arthroplasty (respectively MBUA and FBUA). Squat was analysed during descent, maintenance and ascent phase and described by speed, angular kinematics of lower and upper body, the Center of Pressure (CoP) trajectory and muscle activation timing of quadriceps and biceps femoris. Results: Compared to CTR, for TKA and MBUA knee maximum flexion was lower, vertical speed during descent and ascent reduced and the duration of whole movement was longer. CoP mean distance was higher for all arthroplasty groups during descent as higher was, CoP mean velocity for MBUA and TKA during ascent and descent. Conclusions: Unconstrained squat is able to reveal differences in the functional performance among control and arthroplasty groups and between different arthroplasty designs. Considering the similarity index calculated for the variables showing statistically significance, FBUA performance appears to be closest to that of the CTR group. Level of evidence: III a.KEY WORDS: angular kinematics, Center of pressure, electromyography, unconstrained squat, unicompartmental knee arthroplasty, total knee arthroplasty.
