Extensor mechanism repair and reconstruction using Achilles tendon allograft after bilateral patellar tendon rupture in a patient with rheumatoid arthritis.
Here we report spontaneous rupture of the bilateral patellar tendons in a 49-year-old man with rheumatoid arthritis. The ruptured tendons were sutured via bone tunnels using Krackow stitch, and the extensor mechanism of the knee was reinforced with three bundles of allograft Achilles tendons. The patient recovered well after operation. He could actively flex, extend the knees and carry out full-weight-bearing activities, and he resumed the former employment 6 months after the operation. Follow-up showed that the patient had satisfactory range of motion of the knees 1 year later.
