Knee Kinematics and Kinetics During Locomotor Activities of Daily Living in Subjects with Knee Arthroplasty and in Healthy Control Subjects

Aims and Objectives: In recent decades, knee arthroplasty (KA) succeeded to improve patients’ clinical scores and gait patterns [1]. However, to date, studies primary focused on biomechanical analysis of level walking with total knee arthroplasty (TKA) patients. The investigation of neuromuscular more challenging activities of daily living (ADL) like stair climbing and especially ramp negotiation was partly neglected [2]. Furthermore, non-sagittal plane parameters have mostly not been considered, whereby the evaluation of e.g. transverse plane kinematics and kinetics may reveal potential differences between various endoprosthetic designs. Additionally, frictional forces transmit appreciable shear between the femoral component and the tibial polyethylene insert, potentially contributing to axial knee rotational constraints and implant loosening [3]. The aim of this study was to investigate transverse plane kinematics and kinetics in connection with the force of friction (FOF) during ADL in patients after TKA and unicondylar knee arthroplasty (UKA) surgery. Materials and Methods: - Motion analysis was performed using a ten-camera 3D- motion capture system (100 Hz, Vicon). - Ground reaction forces were measured utilizing in a total five force plates (1000 Hz, Kistler) - Kinematics and inverse dynamics were calculated with AnyBody Modeling SystemTM (AnyBody Technology). - FOF was estimated of the two articulating artificial surfaces (#CHR: mu_LOWER# =0.12) compared with the cartilage on cartilage friction (#CHR: mu_LOWER# =0.01). The Coulomb model of friction was applied to calculate FOF (Ff=Fn* #CHR: mu_LOWER#). - Completed ADL: level and decline walking, stair descent. - Participants: TKA (n=11), UKA (n=13), controls (CG, n=13). - Statistics: Statistical non-Parametric Mapping (SnPM). Results: No statistically significant differences were detected between the TKA and UKA group, regardless of the locomotion task. Each motor task revealed impaired knee internal rotation angles in the TKA group compared with the CG (Fig. 1, a-c). Fig. 1 (d) clarifies the determining role of the coefficient of friction regarding FOF which showed the highest values during stair ascent and decline walking in all groups. Interestingly, the mentioned tasks exposed lower knee internal moment time series compared with level walking. Lower internal rotation moments might contribute in connection with high friction to the constraint knee internal rotation motion, particularly during ADL including greater normal force values, such as stair climbing and ramp negotiation. Conclusion: Apart from implant congruency in the TKA group, FOF could represent a mechanical resistance, which contributes to the impaired knee motion in the transverse plane.

AbstractThe aim of this study was to analyze the extent to which postoperative patellofemoral joint (PFJ) kinematics assessed at 6-month follow-up after total knee arthroplasty (TKA) mimics the intraoperative kinematics after final component implantation. The study hypothesis, already proved in terms of tibiofemoral joint (TFJ) kinematics, is that the intraoperative assessment of PFJ kinematics after component implantation is also capable of predicting postoperative knee kinematics during activities of daily living. Twenty patients selected for TKA with patellar resurfacing were implanted using surgical navigation, including patellar component positioning via a novel computer-assisted procedure. This allowed for intraoperative TFJ and PFJ kinematic assessment after final component implantation. At 6-month follow-up, all patients were contacted for follow-up control; in addition to clinical examination, this implied postoperative kinematics assessments by three-dimensional video fluoroscopy of the replaced knee during standard activities of daily living. Several traditional PFJ, as well as TFJ, rotations and translations were calculated intra- and postoperatively and then statistically compared. Good postoperative replication of the intraoperative measurements was observed for most of PFJ variables analyzed, as well as those for TFJ. Relevant statistical analysis also supported the significant consistency between the intra- and postoperative measurements. Pertaining to the present findings on a statistical basis, intraoperative measurements performed at both TFJ and PFJ kinematics using a surgical navigation system under passive conditions, are predictive of the overall knee kinematics experienced at postoperative follow-ups by the same replaced knees in typical activities of daily living.

Purpose To better define the clinical characteristics of idiopathic oromandibular dystonia, we studied voice, speech, and swallowing disorders and their impact on activities of daily living. Method Fourteen consecutive patients with idiopathic oromandibular dystonia and 14 matched, healthy control subjects were included in the study. Results Dysarthria was the most common disorder and its characteristics varied from one patient to another. However, we frequently observed a hyperkinetic, dysarthric profile characterized by imprecise consonants, a rough voice, changes in intensity, and hypernasality. Dysphagia appeared to be slightly less frequent and less disabling than dysarthria. Most patients had difficulty swallowing solids, and the oral phase was particularly problematic. Dysarthria and dysphagia affected activities of daily living in general and the psychological/emotional domain in particular. Conclusions The characteristics of dysarthria in oromandibular dystonia vary significantly from one patient to another due to differences in the set of affected muscles, so each patient should receive a personalized rehabilitation program. Dysarthria was the most prominent symptom, although spasmodic dysphonia was more frequent than expected. Further laboratory-based studies are needed to clarify the mechanisms and consequences of dysphagia in oromandibular dystonia.

Muscle Loading

Many activities of daily living during work, exercise, religious worship, and hobbies require deep knee flexion. Activities such as rising from a low chair or getting into or out of a bath require between 100° and 160° of knee flexion [1]. Other activities such as kneeling or squatting to pick an item off the ground can be difficult with a limited range of motion. Beside deep knee flexion being important for daily living activities, it is essential in non-Western cultures that commonly sit in deep knee-bending positions. In vitro studies looking at knee function often focus solely on the knee joint, ignoring the effect of the muscle, ligament, and tendon constraints of the ankle, and simplifying or neglecting muscle loads. The effects of these assumptions on kinematics are unknown. The purpose of this study was to compare a squatting activity for: 1) whole leg versus knee specimens, and 2) different combinations of quadriceps and hamstrings loading.
