Pain, swelling and limited knee movement are indicators of arthritis in the knee. People who suffer this disorder will find difficulty moving the joint in the mornings, however, stiffness decreases by gradually increasing motion.
At other times, as with other knee conditions, the joint produces clicking sounds when bent or straightened, and may lock suddenly.
An accurate diagnosis can be made after undergoing medical assessment and x-rays.
Other methods used diagnose rheumatoid arthritis include :
- Blood tests
- Fluid analysis – laboratory analysis of fluid samples from the knee will help diagnose the type of arthritis suffered.
- Arthroscopy – a doctor may order this test to directly view and assess the extent of cartilage, tendon and ligament damage. Arthroscopy is usually conducted prior to corrective surgical procedures to repair the knee.
