“…Manual digitizations of anatomic landmarks often produce large amounts of variability (Perrin et al, 2005) and the roughness and geometry of the surface have been found to affect accuracy (Luo et al, 1996). The current results also strongly suggest that care must be taken in the digitization of anatomical structures during computer-assisted surgical procedures.…”

“…Hsu et al used magnetic tracking devices to obtain patellofemoral kinematics and applied these to digitized 3D joint surfaces (cartilage and total knee arthroplasty) to calculate surface proximities. 32,33 Kitaoka et al 41 used a 3Space Tracker system (Polhemus Navigational Sciences Division, Colchester, VT) 104 with a root mean square accuracy of 0.2 mm and 0.5° 40 to measure the frequency at which different regions are in contact under various loading conditions (i.e. the frequency that contact occurred in >50% of a region for six anatomic regions) in the foot.…”

Empirical joint contact mechanics measurement (EJCM; e.g. contact area or force, surface velocities) enables critical investigations of the relationship between changing joint mechanics and the impact on surface-to-surface interactions. In orthopedic biomechanics, understanding the changes to cartilage contact mechanics following joint pathology or aging is critical due to its suggested role in the increased risk of osteoarthritis (OA), which might be due to changed kinematics and kinetics that alter the contact patterns within a joint. This article reviews and discusses EJCM approaches that have been applied to articulating joints such that readers across different disciplines will be informed of the various measurement and analysis techniques used in this field. The approaches reviewed include classical measurement approaches (radiographic and sectioning, dye staining, casting, surface proximity, and pressure measurement), stereophotogrammetry/motion analysis, computed tomography (CT), magnetic resonance imaging (MRI), and high-speed videoradiography. Perspectives on approaches to advance this field of EJCM are provided, including the value of considering relative velocity in joints, tractional stress, quantification of joint contact area shape, consideration of normalization techniques, net response (superposition) of multiple input variables, and establishing linkages to regional cartilage health status. EJCM measures continue to provide insights to advance our understanding of cartilage health and degeneration and provide avenues to assess the efficacy and guide future directions of developing interventions (e.g. surgical, biological, rehabilitative) to optimize joint’s health and function long term.
