Knee Pathology

The current study aims to assess the sensitivity and specifi city of magnetic resonance imaging by reference to arthroscopy in the preoperative diagnosis of knee pathologies. In this retrospective study, pre-operative knee magnetic resonance imaging reports of 70 patients were reviewed by a blinded musculoskeletal radiologist and compared with the respective arthroscopic fi ndings recorded in the operative notes. Pre-operative magnetic resonance imaging demonstrated a sensitivity level of 92.7% and 61.3% and specifi city level of 33.3% and 53.9% in detecting pathologies of the medial and lateral menisci, respectively. With respect to the cases of complete anterior cruciate ligament tear, sensitivity was 76.7% with 92.5% specifi city. On the other hand, magnetic resonance imaging demonstrated 100% sensitivity and 90.7% specifi city in the diagnosis of posterior cruciate ligament partial tear. Relatively better sensitivity in detecting cruciate ligaments pathology and better specifi city in detecting menisci pathology was reported using magnetic resonance imaging. Almost 25% of complete anterior cruciate ligament injuries may remain undetected in preoperative magnetic resonance imaging reports, while they represent the most prevalent knee injury. Magnetic resonance imaging should be used with caution in knee pathology and arthroscopy continues to be the gold standard.

Mri Measurements

AbstractThis systematic review explored the utility of preoperative magnetic resonance imaging (MRI) as a tool for predicting intraoperative graft size for anterior cruciate ligament (ACL) reconstruction. Three databases (EMBASE, PubMed, and MEDLINE) were searched in November 2017 for English-language studies of all levels of evidence that aimed to correlate preoperative MRI measurements of common primary ACL autograft sources to intraoperative measurements of the harvested graft. Two reviewers applied predetermined inclusion/exclusion criteria to independently complete title, abstract, and full-text review of eligible studies. Data abstraction, quality assessment, and descriptive statistics are presented. A systematic screen of 930 titles resulted in 14 studies satisfying inclusion/exclusion criteria. These studies examined 762 patients of mean age 28.6 (9–67) years, with 37.3% females. Comparing the correlation of preoperative MRI measurements to intraoperative harvested measures, the strength was very highly positive for quadriceps tendon (QT) (one study, 29 patients, intraclass correlation coefficient [ICC] = 0.96), highly positive for patellar tendon (two studies, 28 patients, ICC: 0.77–0.87), negligible-highly positive for semitendinosus-only tendon (eight studies, 439 patients, r: 0.16–0.81), and negligible-moderately positive for gracilis-only tendon (four studies, 143 patients, r: 0.29–0.59). When combined semitendinosus–gracilis tendon grafts were considered, the correlation ranged from low-very highly positive (10 studies, 517 patients, r: 0.42–0.93). Preoperative MRI assessment of both QT and bone–patellar tendon–bone autografts most highly correlates with intraoperative measurements of autograft diameter. Considerable variability exists when viewing hamstring tendons either individually or together, where most studies indicate at least a moderate correlation. This highlights the advantage of MRI during the preoperative planning process in equipping the surgeon with a better ability to ensure the diameter of the intended autograft will suffice. This is a Level IV study, systematic review of Levels II to IV studies.

Magnetic resonance imaging has become the gold standard for soft tissue lesions evaluation especially after a traumatic event where there is need for diagnostic confirmation. The objective of the current paper was to evaluate the ability of magnetic resonance imaging in diagnosing soft tissue lesions in patients who underwent anterior cruciate ligament reconstruction compared with arthroscopic findings. Through the ability to diagnose soft tissue injuries, particularly meniscal lesions, magnetic resonance imaging should be considered as fundamental in guiding therapeutic management in patients with anterior cruciate ligament lesions.

Anterior Cruciate

Background: Anterior cruciate ligament (ACL) tears are common injuries; they are often associated with concomitant injuries to other structures in the knee, including bone bruises. While there is limited evidence that bone bruises are associated with slightly worse clinical outcomes, the implications of bone bruises for the articular cartilage and the risk of developing osteoarthritis (OA) in the knee are less clear. Recent studies suggest that the bone bruise pattern may be helpful in predicting the presence of meniscal ramp lesions. Evidence Acquisition: A literature review was performed in EMBASE using the keyword search phrase (acl OR (anterior AND cruciate AND ligament)) AND ((bone AND bruise) OR (bone AND contusion) OR (bone AND marrow AND edema) OR (bone AND marrow AND lesion) OR (subchondral AND edema)). Study Design: Clinical review. Level of Evidence: Level 4. Results: The literature search returned 93 articles of which 25 were ultimately included in this review. Most studies identified a high prevalence of bone bruises in the setting of acute ACL injury. Individual studies have found relationships between bone bruise volume and functional outcomes; however, these results were not supported by systematic review. Similarly, the literature has contradictory findings on the relationship between bone bruises and the progression of OA after ACL reconstruction. Investigations into concomitant injury found anterolateral ligament and meniscal ramp lesions to be associated with bone bruise presence on magnetic resonance imaging. Conclusion: Despite the ample literature identifying the prevalence of bone bruises in association with ACL injury, there is little evidence to correlate bone bruises to functional outcomes or progression of OA. Bone bruises may best be used as a marker for concomitant injury such as medial meniscal ramp lesions that are not always well visualized on magnetic resonance imaging. Further research is required to establish the longitudinal effects of bone bruises on ACL tear recovery. Strength of Recommendation Taxonomy: 2.
