Degenerative Arthritis - Osteoarthritis - Diagnosis

Laboratory studies:
-There are no specific laboratory abnormalities for osteoarthritis
the acute-phase reactants and erythrocyte sedimentation rate arenormal
synovial fluid-analysis indicates predominant mononuclearleukocyte sub 2000/microL.

Imaging Studies:
Radiography of affected joints, bone spurs show thischaracteristic, asymmetric collapse joint space, subchondralsclerosis, subchondral cyst formation.
Arthrocentesis is often performed to support the differentialdiagnosis of septic arthritis or crystal. This procedure relieves the pain associated with effusion. Samples of joint fluid is sent to theanalysis if infection is suspected or crystal arthritis.
Arthroscopy is indicated after all conservative treatments havefailed. Procedure directly visualize joint.
The differential diagnosis is made ​​with the following conditions:rheumatoid arthritis, reactive arthritis, condrocalcinoza.
