I cannot thank you all enough. either bone-tendon-bone autograft or hamstring autograft: a retrospective The alternate hypothesis postulates that the cyclops lesion results from not only the natural fibroproliferative process but also largely from the drilling process of the tibial tunnel and bony fragments left after the drilling. We reviewed the available literature regarding the cyclops lesion and OMNI Hospitals (INCOR Group), Kothapeta, LB Nagar, Hyderabad, all ACLRs,3,14,20 whereas magnetic resonance imaging (MRI) studies have reported an incidence of Cyclops lesions occur in the minority of cases of ACLR surgery, between 1-10%.
