Turner's syndrome associated with discoid lateral meniscus and Brandt's disease: a case report
This report discusses several possible explanations for the simultaneous presence of these three diseases. A possible explanation in this case is that the discoid lateral meniscus may have been the mechanical stress that caused Brandt's disease because the Turner syndrome patient had a discoid lateral meniscus that may have been induced by some genetic factors related to Turner syndrome.

Commentary
This case reports an unusual combination and begins with a 5-year-old Japanese girl with a history of Turner's syndrome and Blount's disease who came to the hospital complaining of left knee pain. Magnetic resonance imaging showed a disk-shaped lateral meniscus tear, and an arthroscopic partial meniscectomy was performed with good results.
Turner's syndrome is a congenital disorder characterized by short stature, ovarian insufficiency, congenital cardiac malformations, endocrine disorders, osteoporosis, and autoimmune disorders due to disorders of the female X chromosome.
Discoid meniscus is a diagnosis that encompasses a spectrum of meniscal disorders of shape and stability, suggesting that discoid meniscus is a congenital disorder, explained by genetic and family factors.
Blount's disease is a pathological medial deformity of the proximal tibial growth segment that can cause severe medial deformity, leg length and joint discrepancy.
In this case, a girl with Turner's syndrome presented with a congenital disk-shaped half-moon, which was explained as a study case of Blount's disease.
