Peroneal Tendon Dislocation and Superior Peroneal Retinaculum Injury Radiology 189:905907, Warren LF, Marshall JL (1979) The supporting structures and layers on the medial side of the knee: an anatomical analysis. MRI, given its superior soft tissue contrast and multi-planar capability, has emerged as the modality of choice in evaluating articular cartilage abnormalities. government site. The images should be scrutinized for the presence of chondral or osteochondral injury, especially if displaced as an intra-articular body, as this may affect surgical management. Findings typically associated with acute lateral patellar dislocation were also assessed and recorded (present or absent) including characteristic bone bruises and osteochondral injuries involving the patella, lateral trochlear facet, and lateral femoral condyle. Unauthorized use of these marks is strictly prohibited. The Medial Patellofemoral Ligament (MPFL) is an hour-glass shaped ligament made of bands of retinacular tissue. Additionally, complex injuries to bone, cartilage, and ligaments may occur. The longitudinal stabilizer is the extensor mechanism itself, which is comprised of the quadriceps tendon proximally and the patellar tendon distally. Because as noted above, the femoral bone bruise occurs as the patella moves forward during reduction, bone bruises at the lateral femoral condyle always course anteriorly from the site of any femoral chondral injury that may be present. PubMed official website and that any information you provide is encrypted This can provide a road map for formulating a treatment strategy that would be primarily aimed at stabilizing the patellofemoral joint to halt or slow the progression of articular cartilage loss. On the other hand, the PTI is significantly altered with knee flexion [37]. The injured retinaculum had an indistinct, irregular appearance associated with edema and hemorrhage.
