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

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