Intercondylar notch width on Xray in tunnel view acts as good predictor of susceptible population for Anterior cruciate ligament problems. In one study, normal for adult males was 0.206 ,and females 0.208. On followup those developed ACL subsequently has significantly reduced notch width (males 0.178 and females 0.172)
Does that mean, smaller notch width will cause ACL tear? No it means , the ACL is more susceptible because of bio-mechanics. Submitted by Dr MGK Murthy.
