Chronic patellar tendon injury: Case report and surgical technique

Chronic patellar tendon rupture is uncommon, but it is a debilitating injury. Different surgical techniques have been described in the literature including the use of ipsilateral semitendinosus with or without gracilis tendon autograft, contralateral bone-tendon-bone autograft, Achilles tendon allograft, and artificial ligament. However, there is no large case series have been published about this uncommon in injury, patellar tendon rupture becomes chronic if diagnosed which may lead to proximal migration of the patella, thigh muscle wasting, and decreased knee range of motion, the purpose of this case report is to present an easy technique to reconstruct the patellar tendon with semitendinosus and gracilis quadruple autograft and restore the position of the migrated patella by V-Y quadriceps plasty.
