Thus, to assess for maltracking specifically, a multi-stage CT with a variable number of repeated acquisitions at variable degrees of flexion can also be performed [57]. It thickens as it inserts onto the lateral border of the patella, quadriceps tendon and patellar ligament. The transverse band attaches to the upper pole of the patella, and this component originates on a bony groove that lies between the adductor tubercle and the medial epicondyle, slightly posterior to the epicondyle. This procedure involves removal of cancellous bone beneath the trochlea followed by fixation of the articular surface [88, 89].

The Anterolateral Ligament of the Knee: MRI Appearance, Association As the knee joint ranges from extension to flexion, the articular surface area of the patella is in contact with the femur changes. On the other hand, there are static MRI measurements that are routinely used as indicators of patellofemoral alignment during knee movement [30, 31]. Kamel S, Kanesa-Thasan R, Dave J et al. MRI, given its superior soft tissue contrast and multi-planar capability, has emerged as the modality of choice in evaluating articular cartilage abnormalities. Bone bruises at the anterolateral aspect of the lateral femoral condyle and at the inferomedial patella are the most constant findings in patients who have sustained a recent patellar dislocation. As with the anatomy, there is considerable variability in both the surgical and radiology literature regarding the location of soft tissue injuries in patients following patellar dislocation. Unable to process the form. A tight lateral retinaculum can tilt the patella leading to increased pressure on the lateral facet causing pain (Ficat). The typical injury pattern is a tear of the medial patellofemoral ligament (MPFL) and bone bruises of the patella and the lateral femoral condyle. The ratio of the medial to the lateral facet length defines trochlear facet asymmetry (MT/LT) *100%. Most, however, agree regarding the importance of the MPFL and its role as the strongest restraint to lateral patellar displacement.
