To Explore The Operative Method And Efficacy Of Arthroscopic Management Of Discoid Meniscus Injury

Objective: To explore the efficacy of discoid meniscus injury urder arthroscop in different operative method for clinical research.Methods: From April 2002 to October 2007,119 cases of discoid meniscus were under went arthroscopic partial or total meniscectomy in the light of type and injury condition.58 cases were complete,55 was incomplete and 6 was Wrisberg-type by the Wat(?)nabe classification.There were 54 males and 65 females.
