arthroscopy

1.Dorsally, the starting point is just proximal to the standard 3-4 radiocarpal arthroscopy portal.

背侧入路时，进入点刚好接近于标准桡腕3-4入口处。

2.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，内手术有优异的疗效。
