Diagnostic Criteria

There is no specific signs and symptoms or even there is no specific for osteoarthritis (OA) diagnose. But the osteoarthritis is diagnosed based on several elements such as patients age, past medical history, and available symptoms. Osteoarthritis of the major joints is diagnosed using a combination of patients past medical history, physical examination, and variety of lab tests including imaging studies such as X-ray.

Classification Criteria for Osteoarthritis of the Hip

Traditional format

Hip pain plus at least two of the following: ESR of less than 20 mm per hour Femoral or acetabular osteophytes on radiographs Joint space narrowing on radiographs

Classification-tree format

Hip pain plus femoral or acetabular osteophytes on radiographs OR Hip pain plus joint space narrowing on radiographs and an ESR of less than 20 mm per hour

ESR = erythrocyte sedimentation rate. Adapted with permission from Altman R, Alarcon G, Appelrouth D, Bloch D, Borenstein D, Brandt K, et al. The American College of Rheumatology criteria for the classification and reporting of osteoarthritis of the hip. Arthritis Rheum 1991;34:505–14.

Classification Criteria for Idiopathic Osteoarthritis of the Knee

Traditional format

Knee pain plus osteophytes on radiographs and at least one of the following: Patient age older than 50 years Morning stiffness lasting 30 minutes or less Crepitus on motion

Classification-tree format

Knee pain and osteophytes on radiographs OR Knee pain plus patient age of 40 years or older, morning stiffness lasting 30 minutes or less and crepitus on motion

Classification Criteria for Osteoarthritis of the Hand

Hand pain, aching or stiffness + Hard tissue enlargement of two or more of 10 selected joints* + Fewer than three swollen metacarpophalangeal joints + Hard tissue enlargement of two or more distal interphalangeal joints OR Deformity of two or more of 10 selected joints*

* —The 10 selected joints are the second and third distal interphalangeal joints, the second and third proximal interphalangeal joints and the first carpometacarpal joints (of both hands).
