Final answer:
Evidence of bony or cartilaginous pathology, osteochondral defects, or narrowing of the joint space can be observed in X-rays or diagnostic imaging tests and are indicative of osteoarthritis (OA).
Step-by-step explanation:
Evidence of bony or cartilaginous pathology, osteochondral defects, or narrowing of the joint space can be observed in X-rays or diagnostic imaging tests and are indicative of osteoarthritis (OA).
OA is typically diagnosed based on signs and symptoms such as joint deformities, pain, and stiffness. X-rays can show changes in the joint structure, including bone spurs, joint space narrowing, and osteochondral defects.
These findings are important for confirming the diagnosis and form part of the assessment criteria for OA.
