Organ reserve vs synovial joint pathologic age vs disease symptom stage in OA, including illustrative examples; Solid line: observation where organ reserve, synovial joint pathologic age and symptom disease stage are congruent. Dotted line: observation of relatively preserved organ reserve despite advanced synovial joint pathologic age with absence of disease symptoms. Dashed line: observation of severe disease symptoms with moderate diminished organ reserve and relatively preserved synovial joint pathologic age.
