19 cases of pyogenic arthritis of the knee in adults were treated in the last 10 years. There were 5 males and 14 females. The mean age of patients was 69 years old. The most important predisposing factor was intraarticular administration of corticosteroid, which was given frequently to 12 cases of osteoarthritis and one case of pseudogout of the knee. The organisms cultured from the synovial fluid were Staphylococcus aureus in 11, Streptococci in 5, Pseudomonas in 1 case and cultures were negative in 2 cases.14 cases were treated by synovectomy and continuous irrigation followed by early passive motion. Of the 15 cases which were examined for the presence of pain and the ROM of the knees, 7 who had good results were operated on in an average of 7 days after onset, 5 who had fair results were operated on in an average of 31 days after onset and two had poor results (one was a recurrent case of chronic pyogenic arthritis and another had candida infection). Surgical intervention for pyogenic arthritis of the knee in adult should be performed as early as possible to improve the functional results.
