Knee Flexion Deformity and Increased Posterior Tibial Slope Associated with Osgood Schlatter Disease: A Case Report and Review of Literature

Genu recurvatum associated with Osgood-Schlatter disease (OSD) has been reported in several studies. In this report, we describe a rare complication of a case of OSD with flexion contracture (tfighat is the exact opposite of the knee deformity classically associated with OSD) and increased posterior tibial slope.In the current article, we report a ۱۴-year-old case of OSD referred to our center with a fixed knee flexion contracture. Radiographic evaluation revealed a tibial slope of ۲۵ degrees. There was no limb length discrepancy. Bracing that was prescribed in the primary centerbefore referring to us was not successful in treating this deformity. He underwent anterior tibial tubercle epiphysiodesis surgery. After a year, the flexion contracture of the patient was significantly reduced. The tibial slope decreased by ۱۲ degrees and reached ۱۳ degrees.The present report suggests that OSD may affect the posterior tibial slope and lead to knee flexion contracture. Surgical epiphysiodesis can correct the deformity.Level of evidence: IV
