“…Because AP translation is small and can be affected by the choice of assessment system, few studies have analysed movments in this plane [2,12]. The quasistatistcal fixation of our assessment system is the first to examine anterior-posterior translation during walking [13,14]. The objective of this study was to use 3D motion analyses (KneeKG TM ) to identify changes in kinematic variables of patients with OA of the knee during a complete gait cycle and to correlate them with clinical characteristics.…”

Purpose Although kinematic changes in the sagittal plane of the osteoarthritic knee (OA) have been elucidated, very few studies have analysed changes in the frontal and horizontal planes. Therefore, the aim of this study was to investigate in vivo 3D knee kinematics during walking in patients wth knee OA. Methods Thirty patients with medial knee OA and a control group of similarly aged individuals were prospectively collected for this study. All participants were assessed with KneeKG TM system while walking on a treadmill at a selfselected speed. In each trial, we calculated the angular displacment of flexion/extension, abduction/adduction and external/internal tibial rotation. Statistical analysis was performed to determine differences between the knee OA group and the control group.

Background: Numerous studies use a biomechanical assessment to evaluate joint function in knee pathologies such as osteoarthritis. However, most of them focus only on the knee and the consequences of the pathology on other lower limb joints are poorly documented. The objective of this study is to analyze the impact of knee osteoarthritis on ipsilateral hip, knee and ankle joint during gait. Methods: Three-dimension (3D) angular kinematic patterns of the three joints were analyzed on 32 patients diagnosed with knee osteoarthritis (OA) and a control group of 15 asymptomatic subjects (AS). Kinematic data was captured during treadmill gait trials at a self-selected comfortable speed. Analysis of covariance (ANCOVA) was performed on selected points of interest from 3D kinematic patterns of the hip, knee and ankle joints to compare both groups. The significance level was set at p = .05. Results: Gait 3D kinematic gait patterns of OA patients revealed significant differences with those of AS subjects at the three joints. Conclusions: Results suggest that patients with knee osteoarthritis also present alterations in hip and ankle kinematic during gait that should be considered when tailoring conservative treatments.

“…The dynamic squats were standardized with a proprioceptive jig . The KneeKG™ provides repeatable and reliable measurements (Lustig et al 2012), but they are still influenced by soft tissue artefacts (STA) with kinematics errors up to 7° and 11 mm (Südhoff et al 2007). These STA errors were therefore corrected with a multi-body optimization method (MBO) (Gasparutto et al 2015) The lower limb model used in MBO consisted of 4 segments (pelvis, femur, tibia, foot) imposing spherical joint constraints at the hip and ankle, and parallel mechanism constraints at the knee.…”

The KneeKG system: a review of the literature

Abstract: The KneeKG™ system provides reliable movement analysis. This system has the potential to improve understanding the biomechanical consequences of trauma or degenerative changes of the knee as well as more accurately quantify rotational laxity as detected by a positive pivot-shift test.
