title: Prepatellar continuation rupture: Report of an unusual case.
abstract: In anatomical studies the deepest soft tissue layer, related to the deep rectus femoris tendinous fibers, has been described as the "prepatellar quadriceps continuation". We present an unusual case of an isolated prepatellar continuation rupture, which to our knowledge is the first described case in the literature. Injuries to the extensor mechanism may include isolated rupture of the prepatellar continuation with intact quadriceps and patellar tendons. Diagnosis may be difficult with ultrasound scan and requires MRI scan for confirmation. Appropriate clinical assessment and regular physiotherapy lead to a full functional recovery.
