Congenital Absence of Patella: A Case Report

Congenital absence of the patella is a rare orthopedic pathology characterized by underdevelopment or complete absence of the patella. This condition is very rare when isolated and is usually accompanied by other anomalies. Case Presentation: We report here a case of bilateral congenital absence of the patella in a 6-and-a-half-year-old boy who presented with walking difficulties and genu valgum, with the incidental discovery of patellar agenesis without any deficit in joint mobility. Radiological and biological assessments confirmed patellar aplasia without evidence of an associated syndrome. Management: We have planned growth modulation for his genu valgum and a transfer of the anterior tibialis to the third cuneiform for his supinated foot, but no treatment is currently planned for the patellar agenesis due to the absence of symptomatic issues related to this agenesis.
