Abstract
Background
A Comparative Study of Intercondylar Notch Width Ratio and Posterior Tibial Slope in persons with and without ACL injury was undertaken to determine if these parameters vary and if they vary then should these factors be considered before primary or revision ACL surgery .
Methods
50 patients with ACL insufficiency diagnosed clinically and confirmed by MRI were marked as group A . Group B consisted of patients who underwent MRI and reported as normal study . Intercondylar notch width ratio and posterior tibial slope were measured in both groups using standardised methodology and compared .
Results
50 patients with ACL deficient knee in Group A the mean age was 31.74yrs and remaining 50 with NON ACL deficient knee Group B with the age was 36.66yrs. Males were more frequently involved than females. We found mean Intercondylar notch width ration in ACL deficient patients to be 0.29 and in Non ACL deficient to be 0.32. This was found to be statistically significant with a p value of 0.0001, as determined by Chi square test.Intercondylar notch width ratio was less and posterior tibial slope was increased in patients with ACL injury (Group A). The average posterior tibial slope was 10.8 degree in patients with ACL deficient knee (Group A) as compared to 7.4 degree in patients with intact ACL Group B with p value of <0.001.
Conclusions
The clinical and surgical significance of these findings are to be analysed in detail and strategies to normalise both intercondylar notch width ratio posterior tibial slope should considered in primary and more so in revision ACL surgeries for a better outcome and prevent failures.
