A case of rupture of the patellar tendon in a patient with rheumatoid arthritis is presented. The age of this patient (27 years) makes this case quite uncommon. The rupture was bilateral, simultaneous and spontaneous. The absence of previous cortisone administration rules out this drug as a cause of the tendon rupture.
