Yea
I tore up my knee is a tractor trailor accident . I also had an occult fracture bone in the knee area , torn acl , torn meniscus and cartalage . Youll be down for about a week or two and should have no problems riding at all . BUt if you jog , or do martial arts or any other high impact stuff on the knee , you may have problems . Biking is in no way a problem what so ever and you can get your cardio that way , or even compete .
Good luck
