Abstract

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 14-year-old case of OSD referred to our center with a fixed knee flexion contracture. 
Radiographic evaluation revealed a tibial slope of 25 degrees. There was no limb length discrepancy. Bracing that 
was prescribed in the primary center
before 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 
12 degrees and reached 13 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
