[Arthroscopic treatment of tibial intercondylar ridge avulsion fracture with double-root line double tunnel fixation technique].

Objective: To discuss arthroscopic technique of double-root line double tunnel fixation for tibial intercondylar ridge avulsion fracture and its short-term followvup observational results.

Methods: From May 2012 to June 2017, 21 cases of tibial intercondylar ridge avulsion fractures were treated with arthroscope double line double tunnel. Among the patients, 16 males and 5 females were ranging in age from 17 to 45 years old, with an average of 29.
