Abstract

Patellar tendon rupture is rare and is caused mainly by trauma, but it can also be caused by systemic disease or weakening of the tendon due to aging. Complete rupture may occur in the inferior pole of the patella, midsubstance of the tendon, and the tendon from the tibial tubercle. In addition, it can also appear as an avulsion fracture. The authors experienced a Z-shaped pattern of an acute patellar tendon complete rupture, including partial transverse ruptures of the inferior pole of the patella and the tendon from the tibial tubercle separately with a longitudinal tear. Satisfactory results were obtained through surgical treatment. The authors report this case with a review of the relevant literature.
