The treatment of physeal arrest after infection remains a challenge. This report describes localized endoscopic epiphysiolysis combined with guided growth in the treatment of partial physeal arrest and limb deformity in an infant after infection. Over a year's time, the valgus was corrected and the plate was removed. The patient returned to full activity. Physeal arrest may occur at anytime after physeal trauma, highlighting the importance of long-term follow-up. Endoscopic physeal bar takedown combined with guided growth of the distal femur can be an effective option for the treatment.
