Studies of Hydroarthrosis of the knee in old age

The pathogenesis of Hydroarthrosis in old age is still obscure. It is well known that synovial fluid play an important role for nutrition of articular cartilage. In order to clarify the pathogenesis of osteoarthritis and hydroarthrosis in old age, an attempt has been made by author to determine the total protein levels in synovial fluid of patients with osteoarthritis and hydroarthrosis.1) The total protein levels in synovial fluid of osteoarthritis or hydroarthrosis was approximately 2.8g/dl.2) No relation was found between the total protein levels and the volume of synovial fluid.3) The total protein in the synovial fluid in inflammatory osteoarthritis is higher than that in the non-inflammatory osteoarthritis.
