Femoral Condyle Curvature is Correlated with Knee Walking Kinematics in Ungulates

Abstract: The knee has been the focus of many studies linking mammalian postcranial form with locomotor behaviors and animal ecology. A more difficult task has been linking joint morphology with joint kinematics during locomotor tasks. Joint curvature represents one opportunity to link postcranial morphology with walking kinematics because joint curvature develops in response to mechanical loading. As an initial examination of mammalian knee joint curvature, the curvature of the medial femoral condyle was measured on fe… Show more

“…Mammalian diaphyses and epiphyses join very late or not at all, and do so independently of locomotor habit (Geiger et al 2014). In contrast, epiphyseal joint surface development is extensively influenced by mechanical stresses applied on the joints (Carter et al 1998;Hamrick 1999;Green et al 2012;Sylvester 2015). This matches the fine-grained resolution on locomotor behavior reflected by mammalian epiphyseal shape (Walmsley et al 2012;Fabre et al 2015) and integration patterns (Fabre et al 2014).…”

“…A follow-up partial correlation analysis using just epiphyseal data (the multipledistance index minus the diaphyseal length measurement) bears little resemblance to length-only or multiple-distance analyses ( Fig. In contrast, epiphyseal joint surface development is extensively influenced by mechanical stresses applied on the joints (Carter et al 1998;Hamrick 1999;Green et al 2012;Sylvester 2015). These differences may relate to a developmental mechanism: epiphyses of mammalian limb long bones ossify much later than-almost independently from-the diaphyses, and in marsupials they ossify exclusively postnatally (Hamrick 1999).…”

“…33 In contrast, the knee is subject to flexion angle-based contact loading of articular cartilage given the variable radius of curvature of the femoral condyles and noncongruent, medially concave and laterally convex nature of the tibial plateau. 23,31,58 The current study is not without limitations. While the inclusion of 2 institutions and use of 3 outcome scales provides relative strength to this study, we believe future investigations should aim to include additional centers and outcome measures to provide further multicenter evidence regarding the indications and preferential use of debridement/abrasion and microfracture.…”

“…4,5 The chondral modeling theory indicates that joint morphologies develop in response to mechanical loadings; 6 for example, the femoral condyle curvature has been found to be correlated with walking kinematics. 7 For the challenging yet valuable task to measure articular surfaces in vivo during locomotion, this paper proposes a method to obtain the effective articular profile by monitoring the deformations of a wearable compliant device.…”
