“…For tears of the lateral meniscus, false-negative diagnoses outnumbered false-positives three to one (9 vs. 3). High false-negative rates in lateral meniscal tears have also been reported previously [6,11]. Considerable interobserver variation also occurred in detection of lateral meniscal tears (Kappa=0.56).…”

“…Medial meniscal tears are more common with chronic instability, however, because of the secondary restraining effect of the medial meniscus to anterior tibial translation [1,9]. For medial meniscal tears, sensitivities have ranged from 86% to 96% and specificities from 75% to 94%; respectively, values for lateral meniscal tears have been 64-89% and 87-98% [2,6,16].…”

“…Clinical examination can raise suspicion of ligamentous injury, but MRI is the noninvasive imaging modality of choice for the evaluation of overall knee pathology [15]. MRI accuracy is comparable to that of diagnostic arthroscopy [6,7], and MRI also allows assessment of the internal architecture of the knee. It can distinguish partial from complete rupture and evaluate the knee for associated injuries.…”

This study compares MRI with examination under anaesthesia to surgical findings in evaluating soft tissue injuries in acute multi-ligament knee trauma. Preoperative MRI was done for 44 patients who underwent surgery for grade III ACL and grade III medial collateral ligament (MCL) injury. In 21 cases both ACL and MCL were treated surgically, but in 23 only ACL. Intra-operative and MRI findings were compared. Accuracy of MRI for medial meniscal tears was 88.6%, sensitivity 80%, and specificity 91.2%; accuracy for lateral meniscal tears was 72.7%, sensitivity 55% and specificity 87.5%. Accuracy and sensitivity for severity of ACL tear was 93.2% and of MCL tear 86.4%. In 88.6% of the knees, bone bruises were visible, with anterolateral femoral and posterolateral tibial bone bruise being the most common. MRI revealed no chondral lesion, but arthroscopy revealed 11. In combined ACL-MCL ruptures, the incidence of concomitant injuries is high and the injuries are best detected with MRI.

“…1 Imaging of the knee is a common musculoskeletal application of magnetic resonance imaging (MRI). 2 Despite evidence for the technical and diagnostic performance of MRI for patients with injuries to the menisci and cruciate ligaments, 3,4 there is uncertainty about the appropriate use of MRI and when it should enter the diagnostic pathway for patients with suspected internal derangement of the knee. 5,6 Systematic reviews have shown that MRI is sensitive and specific in detecting lesions of the cruciate ligaments and menisci.…”

GPs commonly see patients with knee problems. Magnetic resonance imaging (MRI) of the knee is an accurate diagnostic test for meniscus and ligament injuries of the knee, but there is uncertainty about the appropriate use of MRI and when it should enter the diagnostic pathway for patients with these problems. AimTo assess the effectiveness of GP referral to early MRI and a provisional orthopaedic appointment, compared with referral to an orthopaedic specialist without prior MRI for patients with continuing knee problems. Design of studyPragmatic multicentre randomised trial with two parallel groups. SettingA total of 553 patients consulting their GP about a continuing knee problem were recruited from 163 general practices at 11 sites across the UK. MethodPatients were randomised to MRI within 12 weeks of GP referral including a provisional orthopaedic appointment, or orthopaedic appointment without prior MRI within a maximum of 9 months from GP referral. The primary outcome measures were the Short Form 36-item (SF-36) physical functioning scale and the Knee Quality of Life 26-item Questionnaire (KQoL-26) at 6, 12, and 24 months. ResultsPatients randomised to MRI improved mean SF-36 physical functioning scores by 2.81 (95% confidence interval [CI] = -0.26 to 5.89) more than those referred to orthopaedics (P = 0.072). Patients randomised to MRI improved mean KQoL-26 physical functioning scores by 3.65 (95% CI = 1.03 to 6.28) more than controls (P = 0.007). There were no other significant differences. ConclusionGP access to MRI yielded small, but statistically significant, benefits in patients' knee-related quality of life but non-significant improvements in physical functioning.
