        <span style="font-size:16px;"><strong>Quadriceps Contusion</strong></span></p>
<p>
        Mechanism: Blunt trauma to the anterior thigh (frequently football helmet or opponents knee)</p>
<p>
        Usually involves the anterior quadriceps (rectus femoris and vastus intermedius)</p>
<p>
        Pain on passive stretch and active contraction</p>
<p>
        Can develop large hematomas</p>
<p>
        Loss of knee flexion is a poor prognosticator</p>
<p>
        Complication: <span style="background-color:#ffff00;">Myositis Ossificans</span> (MO) (5-17%)</p>
<p>
                       Increased risk with delay in treatment > 3 days</p>
<p>
                       Radiographs can lag. Ultrasound in more sensitive</p>
<p>
                       Painful firm area in region of contusion occurring 2 to 3 weeks post injury</p>

<p>
        Prompt treatment….key to good outcome and earlier return to sports</p>
<p>
        Large hematoma can be aspirated. NSAIDs may reduce edema and risk of MO. Splinting</p>
<p>
        Place quadriceps in 120 degrees of flexion for 24 hours following injury (keep muscle lengthened)</p>
