From 1985 July to 1988 Feb., 83 patients of osteoarthritis knee were studied in the Dept of Orthopaedic Surgery. There were 19 males and 64 females. Among them, 23 patients (21 ♀) involved both knees. In term of age, there were only 5 patients under 30 years old (6.02%). In contrary, there were 58 patients who were more than 45 of age (69.88%). It is obvious that the degenerated osteoarthritis is more common in the aged. Fifity-two patients were obese in this series (62.65%), and there were 44 females (84.62%) and 8 males. There is no statistically significant differnece (P<0.05). Therefore, we can make a conclusion that the obese females are easier to get the osteoarthritic knee. The pattern of daily activity living also affected the formation of degenerated arthritis. 74.7% of the total subjects were laborers or hyperactive career. 25.3% of them did light work. In those labor workers, the higher incidence to get injury of soft tissue or joint, the more popularity to get degenerated arthritis. Many ahtuors concerned that the history of trauma was a major facotr to cause degenerated arthritis, but we couldn't demonstrate the relationship between the trauma factor and the incidence of osteoarthritis from this study.
