Büdinger was the first to describe pathological fracture of the cartilage of the patella. See also his later paper in the same journal, 1908, 92, 510-36. Later descriptions by Karl Ludloff, Verh. dtsch. Ges. Chir., 1910, 223-25, and by Arthur Laewen, Beitr. klin. Chir., 1925, 134, 265-307, led to the eponym “Büdinger–Ludloff–Laewen disease”.
