• Quadriceps contracture in children can result from multiple intramuscular injections. We describe here seven patients with this complication. These patients were unable to completely flex the involved knee. At surgery, extensive fibrosis of the quadriceps muscle was found. Lengthening of the scar and contracted muscle and tendon restored a good deal of flexion. If long-term antibiotic treatment is anticipated, the intravenous route should be employed if possible.
