title: Bilateral simultaneous rupture of the quadriceps tendon: a case report.
abstract: We report a case of bilateral simultaneous rupture of the quadriceps tendon, in which there was no predisposing cause for the rupture. The condition is extremely rare, there being but five previously reported cases in the literature (Steiner and Palmer, 1949; Wetzler and Merkow, 1950; Preston and Adicoff, 1962; Dalal and Whittam, 1966; Levy et al., 1971). In only two of these cases (Steiner and Palmer, 1949; Dalal and Whittam, 1966) was there no predisposing cause.
