Se presenta un caso de rotura antigua del tendón rotuliano de la rodilla derecha, en una paciente de 49 años de edad afecta de una artritis reumatoide seropositiva de 20 años de evolución. Quince meses después de la rotura acude a nuestra consulta por primera vez, en silla de ruedas, refiriendo que durante todos estos meses presenta una impotencia funcional absoluta para la extensión de la rodilla que le impide la marcha. Fue intervenida quirúrgicamente realizándole un aloinjerto masivo del aparato extensor de la rodilla rótula - tendón rotuliano - tuberosidad tibial. Tras una evolución postoperatoria de tres años, la paciente camina prácticamente normal y presenta una movilidad de la rodilla de 120° de flexión con una extensión activa de –20° y pasiva completa. En los estudios radiográficos se comprueba la plena osteointegración del aloinjerto.

A case is reported of an old rupture of the right patellar tendon in a 49-year-old patient with seropositive rheumatoid arthritis of 20 years evolution. Fifteen months after the rupture, she was seen in our clinic for the first time. She was confined to a wheelchair and indicated that she had not been able to extend her knee or walk for the last 15 months. A massive allograft of the extensor mechanism (patella - patellar tendon - tibial tuberosity) was implanted. After a postoperative evolution of 3 years, the patient walks almost normally and has a knee mobility of 120° flexion-20° active extension and complete passive extension. Radiographic studies confirmed complete osteointegration of the allograft.

Key words:
