Abstract
Two cases of knee arthritis were experienced. A 22-year-old woman complained of a swelling in the left knee since childhood. X-ray examination revealed narrowing of the femoro-tibial joint space.
There was no immunological abnormality. Since pathological findigs of left knee synovium showed infiltration of neutrophils, we treated her condition as infectious arthritis by antibiotics but was not effective. After considering clinical course of arthritis in several joints, she was diagnosed to have rheumatoid arthritis. She was treated with steroid and gold.
The second case was of a 24-year-old man who complained of pain and swelling in his right knee. He was also treated by antibiotics which did not cure his arthritis. After considering all clinical and pathological findings including lymph follicles and synovial proliferation like villi, he was diagnosed to have rheumatoid arthritis. He was treated with ateroid.
These cases indicate that pathological and clinical findings are very important for diagnosis of knee arthritis.
