What are the common symptoms of OA insidious onset of joint pain w/ movement, limitation of motion, referred pain, minimal stiffness after rest, (systemic symptoms are rare)- acute flares of these symptoms suggest another dx
Why do you get pain in OA if the cartilage is avascualr and aneuritic could cause synovitis, joint capsule/ligament stretchin, periosteal irritation from osteophytes, travecular microfractures, muscle spasm, intraosseous hypertension
What physical exam findings would you expect to find in an OA patient Bondy changes in joint shape, crepitus, malalignement/instability, limited ROM, join line tenderness, cool effusions, spasm or atrophy of adjacent muscle
What lab tests are indicative of OA non really but ESR and RF appropriate for age and synovial fluid shiould be class 1 (non-inflammatory)
What x-ray findings are indicative of OA cartilage loss/joint space narrowing, subchondral sclerosis, osteophytes at joint margins, subchondral cysts
