Cartilage erosion, subchondral bone thickening, osteophytes, and synovitis.

**OA phenotype: post-traumatic (ptOA: ACLT = anterior cruciate ligament transection; ACLR = non-surgical mechanically induced anterior cruciate ligament rupture; DMM = surgical destabilization of the medial meniscus; iaF = intra-articular fracture; MULTI = transection of anterior and posterior cruciate ligaments, medial and lateral collateral ligaments and medial and lateral meniscectomy; s/rJL = single or repetitive joint loading without causing ligament failure; TMCL/MM = transection of the medial collateral ligament and partial or complete medial meniscectomy), over-use (ouOA: e.g. excessive or high-speed running, forced use of one limb by inhibiting load-bearing on another), spontaneous age-associated (aaOA), ovariectomy (ovxOA, high bone turnover), collagenase-induced (ciOA; more inflammatory), post-inflammatory (piOA; e.g. with sufficient time post AIA induction inflammation subsides and pathology is typical of OA), monoidoacetate-induced (miOA; chondrocyte death and marked subchondral bone erosion), papain-induced (papOA; proteolysis of cartilage aggrecan).

&It is recognized that there is continuing debate about whether some of the included models should be considered “OA”, and their inclusion here should not be considered an endorsement. However, until such time as it becomes clear which models do or do not provide information that translates to similar outcomes in human OA, these have been included.

#Validation indicates similar therapeutic studies have been done another animal model of OA. ‘Yes’ means the validation study reported the expected or same result versus the original study; ‘No’ means the validation study reported a different effect.
