    Abstract:
    Chronic synovitis of knee joints that cannot be treated by conservative measure effectively can be treated successfully by the operations through resecting the inflamed synovium. The operations include open synovectomy and arthroscopic synovectomy. The purpose of this study is to compare the two operations in alleviating symptoms and cosmetic effect. There were 42 patients in this study, and they suffered from chronic synovitis of knee joints, including rheumatoid arthritis and non-specific synovitis. Twenty-two knees of 22 patients underwent arthroscopic synovectomy with two to five approaches whose lengths were about 1.0 cm, and 20 knees of 20 patients underwent open synovectomy with two approaches whose lengths were more than 10.0 cm. Patients were evaluated by visual analog scale for pain at the 24th hour after operation. Patients were followed up for 16-20 months and were evaluated by the Ogilvie-Harris scoring system. This study showed that both arthroscopic synovectomy and open synovectomy successfully alleviated the symptoms and the short-term results are similar after operation. However, the scars in the patients of the former group were much shorter than the latter group. Pain intensity of patients underwent arthroscopic synovectomy was less than that of open synovectomy at the 24th hour after operation. Both operations could treat chronic synovitis successfully. However, the arthroscopic synovectomy is the preferred operation due to fast recovery, less postoperative pain, and excellent cosmetic effect.
