“…It has been suggested that they represent a spectrum of radiographically occult bone injuries, ranging from bleeding, infarction and edema to microscopic compression fractures of cancellous bone (Kier et al 1991, Zeiss et al 1995. Bone bruise injuries of the knee, without associated meniscoligamentous injuries, such as we found in 2 of our patients, have been reported before (Mink and Deutsch 1989, Vellet et al 1991, Rangger et al 1996. Most authors consider the lesions to be caused by a fracture.…”

“…In the third patient, tears in the medial and lateral meniscus were treated by partial meniscectomy. These patients form part of a prospective series of MRI investigations before arthroscopy (Rangger et al 1996).…”

“…They were then placed in physiologic saline solution and frozen to -30 O C . Using a rotating shaft with blades, 1 mm slices were cut from the surface of the frozen specimens and photographed (Kathrein et al 1996). MRI was performed with various supraconducting magnets (0.5-1.0 Tesla) and various pulse sequences, utilizing at least a TI-weighted sequence in 2 planes and a T2-weighted sequence in 1 plane.…”

“…The articular cartilage was normal. Since then, bone bruise injuries have been reported frequently in the knee (Mink and Deutsch 1989, Vellet et al 1991, Murphy et al 1992, Stallenberg et al 1993, Stein et al 1995, Zeiss et al 1995, Rangger et al 1996 and also in the wrist, the calcaneus, the foot and ankle, and in the hip (Kier et al 1991, Laorr et al 1995, Shih et al 1995, Soudry and Mannting 1995.…”

“…The results of the present study demonstrate that knee meniscal and cruciate ligament lesions can be accurately diagnosed by magnetic resonance and support the findings of other studies. [37][38][39][40] The high sensitivity and negative predictive value of the magnetic resonance allow excluding a diagnostic arthroscopy in patients with a doubtful clinical exam, [41][42][43][44] saving costs and reducing patient risk. Willians 49 performed a study in which magnetic resonance imaging scans were performed on 69 patients waiting for knee arthroscopy.…”

PURPOSE:To evaluate the diagnostic accuracy of magnetic resonance imaging of the knee in identifying traumatic intraarticular knee lesions. METHOD: 300 patients with a clinical diagnosis of traumatic intraarticular knee lesions underwent prearthoscopic magnetic resonance imaging. The sensitivity, specificity, positive predictive value, negative predictive value, likelihood ratio for a positive test, likelihood ratio for a negative test, and accuracy of magnetic resonance imaging were calculated relative to the findings during arthroscopy in the studied structures of the knee (medial meniscus, lateral meniscus, anterior cruciate ligament, posterior cruciate ligament, and articular cartilage). RESULTS: Magnetic resonance imaging produced the following results regarding detection of lesions: medial meniscus: sensitivity 97.5%, specificity 92.9%, positive predictive value 93.9%, positive negative value 97%, likelihood positive ratio 13.7, likelihood negative ratio 0.02, and accuracy 95.3%; lateral meniscus: sensitivity 91.9%, specificity 93.6%, positive predictive value 92.7%, positive negative value 92.9%, likelihood positive ratio 14.3, likelihood negative ratio 0.08, and accuracy 93.6%; anterior cruciate ligament: sensitivity 99.0%, specificity 95.9%, positive predictive value 91.9%, positive negative value 99.5%, likelihood positive ratio 21.5, likelihood negative ratio 0.01, and accuracy 96.6%; posterior cruciate ligament: sensitivity 100%, specificity 99%, positive predictive value 80.0%, positive negative value 100%, likelihood positive ratio 100, likelihood negative ratio 0.01, and accuracy 99.6%; articular cartilage: sensitivity 76.1%, specificity 94.9%, positive predictive value 94.7%, positive negative value 76.9%, likelihood positive ratio 14.9, likelihood negative ratio 0.25, and accuracy 84.6%. CONCLUSION: Magnetic resonance imaging is a satisfactory diagnostic tool for evaluating meniscal and ligamentous lesions of the knee, but it is unable to clearly identify articular cartilage lesions.
