Magnetic resonance imaging based anthropometric study of knee joint in anterior cruciate ligament insufficient knees

The knee joint is one of the most commonly injured joints, as an isolated injury or as a frequent component in a multiple trauma patient. Injury to the ligaments and menisci affects the stability and normal mechanics of the knee joint, resulting in an impairing unstable knee. Magnetic resonance imaging (MRI) is a useful diagnostic tool in the assessment of injuries to the knee joint, while anterior cruciate reconstruction is a common orthopedic procedure. We set to find in this paper the concordance between MRI and arthroscopic findings. We performed a retrospective analysis of 57 patients who underwent both MRI and arthroscopic intervention, in order to see the accuracy of the imagistic evaluation in anterior cruciate ligament (ACL) lesions. Our findings show that MRI and arthroscopy were in complete agreement in 94.7% of the cases. We also found 2 casesthat had normal ACL on MRI, but intraoperative we found a partial tear of the anterior cruciate ligament. In only one case we found an intact ACL at arthroscopy although it looked ruptured on MRI. For the assessment of ligamentous and meniscal injuries, MRI is accurate and non-invasive modality. It can be used as a first line investigation, but arthroscopy remains the gold standard for definitive and accurate diagnostic for ACL and meniscal injuries.

Knee Joint Loading

Context: Greater anterior knee laxity (AKL) is associated with impaired sensory input and decreased functional knee stability. As functional magnetic resonance imaging (MRI) is the gold standard for understanding brain function, methods to load the anterior cruciate ligament in the MRI environment could further our understanding of the ligament’s sensory role in knee joint stability. Objective: To design and validate an MRI-compatible anterior knee joint loading device. Design: Descriptive laboratory study. Setting: University laboratory study. Participants: Sixteen healthy and physically active females participated (age = 23.4 [3.7] y; mass = 64.4 [8.4] kg). Interventions: The AKL was assessed by a commercially available arthrometer. The AKL was also assessed with a custom-made, MRI-compatible device that produced anterior knee joint loading in a manner similar to the commercial arthrometer while obtaining dynamic structural MRI data. Main Outcome Measurements: The AKL (in millimeters) at 133 N of loading was assessed with the commercial knee arthrometer. Anterior displacement of the tibia relative to the femur obtained at 133 N of loading was measured from dynamic MRI data obtained during usage of the custom device. Pearson correlations were used to examine relationships between the 2 measures. The 95% limits of agreement compared the absolute differences between the 2 devices. Results: There was a 3.2-mm systematic difference between AKL (6.3 [1.6] mm) and anterior tibial translation (3.2 [1.0] mm) measures. There was a significant positive correlation between values obtained from the commercial arthrometer and the MRI-compatible device values (r = .553, P = .026). Conclusions: While systematic differences were observed, the MRI-compatible anterior knee joint loading device anteriorly translated the tibia relative to the femur in a similar manner to a commercial arthrometer design to stress the anterior cruciate ligament. Such a device may be beneficial in future functional magnetic resonance imaging study of anterior cruciate ligament mechanoreception.

The formation of anterior cruciate ligament cysts is one of the rare non-traumatic forms of knee joint lesions with unexplored etiopathogenesis. The formation of cysts of the anterior cruciate ligament is characteristic of younger people. The disease can be asymptomatic, being detected by chance during magnetic resonance imaging of the knee joint, in the case of a symptomatic course of the disease, the main complaints are chronic nonspecific pain, limitation of terminal flexion and extension of the joint, rarely mechanical symptoms. Magnetic resonance imaging is the method of choice for diagnosing these pathological conditions of the knee joint. The arthroscopic aid allows you to successfully combat this condition, while in the absence of a threat to the stability of the joint, debridement of the joint is performed, and if the stability of the joint is threatened, the issue of reconstruction of the anterior cruciate ligament is considered.

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.

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.
