Tibial tubercle apophysitis in cerebral palsy treated with proximal tibial epiphysiodesis: report of two cases with 3-year follow-up.

Tibial tubercle apophysitis, or Osgood-Schlatter disease, is a condition not commonly seen in conjunction with cerebral palsy. The reported radiologic incidence of this association is only 3%. The condition usually responds to conservative therapy, consisting of rest, immobilization, and antiinflammatory agents. Occasionally, a child with cerebral palsy and resistant apophysitis requires surgical intervention. We report two patients with bilateral apophysitis who underwent proximal tibial epiphysiodesis with complete relief of symptoms and rapid return to community ambulation.
