ABSTRACT

Diagnosis: Quadriceps tendon rupture, Medial retinacular tear

History: 48 y/o male presents with pain in anterior aspect of distal right thigh, superior to right knee and increased pain in right knee. The patient has had knee pain for two years that limited his ability to run.

Findings: Lateral radiograph of the knee shows patella baja. Proton-density and gradient-recalled echo sagittal oblique MR images show a complete tear of the quadriceps tendon with high-signal-intensity hemorrhage/edema filling the gap. Separation of the tibial tuberosity without associated edema suggest old Osgood-Schlatter’s disease. T2-weighted fat sat axial images from the level of the distal femoral diaphysis to the femoral condyle show the quadriceps tendon tear with high signal intensity, the tear of the medial retinaculum at its attachment site to the patella with medial and posterior displacement of torn fibers and extensive high-signal-intensity edema/hemorrhage in the soft tissues particularly laterally. A post traumatic chondral defect with subchondral edema was also seen within the medial patellar facet (image not included).

Ddx: Quadriceps tendon rupture Medial retinacular tear

Dxhow: At surgery.

Exam: Physical Exam and Laboratory: Physical examination shows a large deep palpable defect in the soft tissues in the anterior aspect of right thigh, superior to the patella. The patient was unable to extend his right leg. No laboratory data are available.

No MeSH data available.
