Categorization of discrepancies in findings of menisci and cruciate ligament between arthroscopy and MRI
Journal Title: International Journal of Orthopaedics Sciences - Year 2018, Vol 4, Issue 2
Abstract
Background: The stability of the joint is highly dependent on its supporting ligamentous structures, therefore injuries of ligaments and menisci are extremely common. Objective: To categorize discrepancies in findings of menisci and cruciate ligament between arthroscopy and MRI. Methodology: This prospective, comparative observational study was conducted at Ramkrishna Care Hospital, Raipur, Chhattisgarh. Informed consent was taken from all patients undergoing this study. We prospectively studied 67 patients with complaints of knee pain or instability/locking/giving away sensation with history of knee injury between the age group of 15-60 years over a period of 24 months starting from November 2014 to October 2016. Results: MRI showed 100% sensitivity and negative predictive value for ACL tear while specificity was 66.67% and accuracy of 95.52% with positive predictive value of 95.08%. MRI showed 100% positive predictive value for PCL tear while negative predictive value was 98.48%, alongwith sensitivity of 50% with specificity of 100% and accuracy of 98.51%. MRI showed positive predictive value of 57.58% for MM tear while negative predictive value was 88.24%, alongwith sensitivity of 82.61%, specificity of 68.18% and accuracy of 73.13%. MRI showed 75% positive predictive value for LM tear with a negative predictive value of 93.62%, alongwith sensitivity of 83.33%, specificity of 89.80% and accuracy of 88.06%. Conclusion: It was concluded MRI has high accuracy in diagnosing both meniscal and cruciate ligament injuries. The sensitivity for ACL tear is higher as compared to PCL while that of meniscal tear are almost equal.
