Arthroscopy could be recommended to those who haven't got good results by arthrocentesis or those who have already had some sequelae, such as TMJ fibrous ankylosis. 对一些灌洗治疗无效或有后遗症的患者，关节内镜手术有优异的疗效。
Arthrocentesis (Greek:arthros, a joint + kentēsis, puncture) is the clinical procedure of using a syringe to collect synovial fluid from a joint capsule. It is also known as joint aspiration. Arthrocentesis is used in the diagnosis of gout, arthritis, and synovial infections such as septic arthritis.
