We reviewed 31 patients treated by meniscal suture from 1994 to 1998. They consisted 19 males and 12 females with a mean age of 19.1 years (range: 10-34 years). The average follow-up period was 9.6 months (range; 1 to 36 months). We evaluated factors about the return to sports activity after meniscal repair. The important factors are sex (female), age (after 30 years), ligament insuf-ficiency, and type of sports (requiring jumping). The rehabilitation method shoud be considered to shorten the return period to sports activity.
