Abstract
The concentrations of hyaluronan (HA) and chondroitin sulfate (CS) in synovial fluids from patients with traumatic arthritis (TA) with and without hydrarthrosis were measured. The CS in synovial fluids was determined as a marker of cartilage destruction by high performance liquid chromotography. The concentration of HA in synovial fluids was lower in patients with hydrarthrosis than in healthy volunteers and patients with TA without hydrarthrosis, whereas the total amounts of HA and CS and the concentration of CS were higher in patients with hydrarthrosis. To investigate the relation between hydrarthrosis and production of HA in synovial tissues, TA synovial tissue biopsies were stained for HA with biotinylated HA binding region. The intensity of HA staining was higher in specimens from patients with hydrarthrosis than in normal and TA without hydrarthrosis specimens. Thus, there may be a correlation between hyperproduction of HA, cartilage destruction and increase in fluid volume in TA.
