Patellarsehnenruptur

Rupture of the patellar tendon is a rare injury which in most cases affects patients older than 40 years. If a rupture is overlooked or a false diagnosis is made there can be farreaching consequences for the affected patient. Clinically, rupture of the patellar tendon shows an easily recognizable triad of limitation of active knee extension, elevated patella and a palpable depression. Because at least a partial osseus avulsion of the tendon is mostly present, patients often complain of severe pain. Complete rupture of the patellar tendon must always be treated surgically. Contraindications are extensive accompanying injuries and a life-threatening condition of the patient. In order to avoid complications early mobilization and exercise of the patient are necessary. If the diagnosis and therapy are correct good to very good results can mostly be achieved.
