Anterior cruciate ligament injuries are serious conditions which can affect human life,that is the reason numerous investigates have been led to discover peril factors whether modifiable or unmodifiable to stamp out individuals in danger. Thus, the reason for our investigation is to see if expanded back femoral condyle profundity evaluated as back condyle counterbalance and proportion is a danger factor that may influence rate of ACL wounds . The diagrams of 100 successive patients who went through arthroscopic foremost cruciate tendon medical procedure performed by muscular specialists at Banha college emergency clinic and al Haram emergency clinic from 2017 to 2019 were reflectively looked into. Another 100 patients who were not griping of any knee wounds or shakiness were screened as control group.After patients were screened for qualification, they were partitioned into 2 gatherings: 1. A benchmark group comprising of patients with no neurotic association of the ACL. 2. Patients with ACL injury. Control bunch was coordinated to the investigation bunch by age, sex, stature, weight, and BMI. A patient couldn't be associated with the two gatherings. Applicants were incorporated just in the event that they had excellent standard radiographs, incorporating a horizontal view with <6 mm of cover between the back equal parts of the average and sidelong condyles. Back condyle counterbalance was estimated and recorded and looked at between the two gatherings. Back femoral condyle counterbalance cutoff estimation of >67.8 was related with expanded ACL injury with 76% affectability and 74% particularity. In this way, an expanded back femoral condyle proportion of the distal portion of the femur was essentially connected with expanded pervasiveness of ACL wounds. This investigation found that expanded femoral condyle profundities evaluated as (back femoral condyle counterbalance and back femoral condyle proportion) is related with expanded commonness of ACL wounds.
