Congenital patellar aplasia in conjunction with trisomy 8. A case report.
Congenital patellar aplasia and hypoplasia are quite rare. Bilateral flexion deformity of the fifth finger, patellar aplasia in the right knee and patellar hypoplasia in the left knee were noted in a 6-year-old boy brought in for treatment of curvature of both little fingers. Active and passive movements of the knees were within normal range, and the quadriceps muscle was of normal strength. Trisomy 8 was determined on chromosome analysis. In contrast with the literature, the patellar abnormality was not concomitant with any other syndromes in our case, and most clinical findings of trisomy 8 were absent.
