Abstract:
Objective To investigate the optimal technology of blind needle synovial biopsy.Methotis Blind needle synovial biopsy was performed on 81 knees with pain and swelling.Twenty patients with rheumatoid arthritis (RA) received uhrasonographic (US) examination before biopsies.Results Synovium were obtained in all patients and the successful rate was (71±21)%,while the area of synovium was (1.8±0.8)mm2.The time for accomplishing the procedure was (26±6) min and the depth of trocar insertion Was (3.1±0.7) cm.The successful rate in patients with RA (80±6)% was much higher than that in non-RA patients (54±10)%.The successful rate with US guidance (85±5)% was much higher than that without US guidance (78±6)%.The positive predictive value of synovium evaluation by naked eye Was 95.0%,while the negative predictive value was 81.1%.Conclusion Blind needle synovial biopsy should be spread because it is simple and safe to perfonn and it can obtain sufficient synovium for all purposes.
