Comparison of properties determined using electromechanical assessment (Arthro-BST™) with macroscopic and histological properties in symptomatic human articular cartilage of the hip

Abstract — Editorial summary

Researchers examined fourteen femoral heads removed from thirteen patients undergoing surgery for hip osteoarthritis or fracture. Arthro-BST measurements at selected cartilage sites were compared with visual ICRS grades and two histological systems: modified Mankin and OARSI grading. The electromechanical results correlated significantly with macroscopic severity and several histological measures, including the overall Mankin score. These findings support the probe’s ability to characterize degeneration in excised human hip cartilage. The evidence comes from surgically removed specimens and does not establish a noninvasive screening test for intact hips.
