INTRODUCTION Although being debated for many years, the superiority of posterior cruciate-retaining (CR) total knee arthroplasty (TKA) and posterior-stabilized (PS) TKA remains controversial. We compare the knee scores, post-operative knee range of motion (ROM), radiological outcomes about knee kinematic and complications between CR TKA and PS TKA. METHODS Literature published up to August 20...

BACKGROUND Females have a two-fold risk of developing knee osteoarthritis (OA) as compared to their male counterparts and atypical walking gait biomechanics are also considered a factor in the aetiology of knee OA. However, few studies have investigated sex-related differences in walking mechanics for patients with knee OA and of those, conflicting results have been reported. Therefore, this st...

INTRODUCTION Knee motions are determined by the interaction between active and passive constraints of the joint and forces acting on the joint. Changes in knee kinematics, kinetics, and muscle function are found with ACL injury, specifically, changes in the anterior-posterior (AP) translation and internal-external (IE) rotation of the knee leading to buckling or giving way [1,2]. ACL repair is ...

In this paper, we present a novel visualization approach for the quantitative analysis of knee movement patterns in time-varying data sets. The presented approach has been developed for the analysis of patello-femoral instability, which is a common knee problem, caused by the abnormal movement of the patella (kneecap). Currently, patello-femoral analysis is based on acquisitions performed durin...

BACKGROUND Various implants of total knee arthroplasty (TKA) are used in clinical practice and each presents specific design characteristics. No implant managed this day to reproduce perfectly the biomechanics of the natural knee during gait. OBJECTIVES We therefore asked whether (1) differences in tridimensional (3D) kinematic data during gait could be observed in two different designs of TK...

BACKGROUND By altering muscular activation patterns, internal forces acting on the human body during dynamic activity may be manipulated. The magnitude of one of these forces, the medial knee joint reaction force (JRF), is associated with disease progression in patients with early osteoarthritis (OA), suggesting utility in its targeted reduction. Increased activation of gluteus medius has been ...

BACKGROUND Currently the clinical standard for measuring the motion of the bones in knee joints with sufficient precision involves implanting tantalum beads into the bones. These beads appear as high intensity features in radiographs and can be used for precise kinematic measurements. This procedure imposes a strong coupling between accuracy and invasiveness. In this paper, a tri-plane B-mode u...

INTRODUCTION Side-cutting tasks are commonly used in dynamic assessment of ACL injury risk, but only limited information is available concerning the reliability of knee loading parameters. The aim of this study was to investigate the reliability of side-cutting data with additional focus on modelling approaches and task execution variables. METHODS Each subject (n=8) attended six testing sess...
