Assessment of Inflammation In Vivo Ankle joint diameters have been measured in CFA-induced arthritis, and knee joint diameters were measured for MIA-induced arthritis. Joint diameters of each legs had been measured applying a digital caliper to evaluate swelling degree. Each absolute increase in joint diameter and the ratio involving treated and intact joints (in percent of the intact joint) of your same animal had been assessed. Joint diameter ratio was calculated according to the following equation:.
