The value of synovectomy of the knee in the treatment of rheumatoid arthritis.

The goal of the present study is to evaluate the usefulness of synovectomy of the knee joint in patients with rheumatoid arthritis. Synovectomy of the knee is the most common lower limb operation performed in patients with rheumatoid arthritis. Depending on the stage of the disease, the symptoms, and the degree of intra-articular changes in the radiological image, there are indications for performing both early and late synovectomy. The progress of the disease is not dependent on its duration, but on the aggressiveness and dynamics of the rheumatoid process. The authors present the advantages of early synovectomy, which halts the progress of the disease and protects the joint from destruction. After early synovectomy one obtains an average of 75% good outcomes, while after late synovectomy the percentage of positive outcomes is about 70%. The authors point out the effectiveness and low level of invasiveness of arthroscopic synovectomy, thanks to which the progress of the disease can be checked and monitored. Another possible therapy is chemical synovectomy, with the specific action of radioisotopes: synoviorthosis with laser irradiation. The authors emphasize that an important factor in obtaining good outcome after every synovectomy is rehabilitation, during which the range, frequency of exercise, and physicotherapeutic procedures are established, depending on the stage of advancement of the rheumatoid process.
