Osteoarthritis (OA) is the most common cause of joint pain. Animal models and relevant assays for measurement of pain-related behaviours are important tools for studies of mechanisms inducing and sustaining pain in OA. The aim of this study was to evaluate two different assessments of weight bearing; stationary and during locomotion, and to explore their feasibility to detect analgesic effects in vivo. Two fundamentally different mouse models of joint arthritis were investigated; surgical transection of the anterior cruciate ligament (ACLT) resulting in destabilization of the joint with subsequent structural deterioration resembling OA, and monoarthritis induced by injection of Complete Freund´s Adjuvant (CFA) into the ankle joint capsule.
