| Objectives To correlate MRI findings and arthroscopic findings in femoroacetabular impingement. Patients and methods A retrospective analysis of the accuracy of MRI findings compared with arthroscopic findings in 60 patients with femoroacetabular impingement. Results Chondral lesions were identified in 19 of 60 patients on MRI and were identified in 30 of 60 patients on arthroscopy. MRI had a sensitivity of 53.33%, a positive predictive value of 84.21%, a specificity of 90%, a negative predictive value of 65.85%, and an accuracy of 71.67% for the detection of chondral lesions. Labral tears were identified in 48 of 60 patients on MRI and were identified in 54 of 60 (90%) patients on arthroscopy. MRI had a sensitivity of 81.4%, a positive predictive value of 91.67%, a specificity of 33.33%, a negative predictive value of 16.67%, and an accuracy of 76.67% for the detection of labral tears. Conclusions MRI cannot be used to rule out a labral tear and chondral lesion when there is a high clinical suspicion and need for therapeutic test in equivocal cases and functional cartilage imaging can be considered in early detection of the disease. | ||
