Real-time sonoelastography of the quadriceps tendon in patients undergoing chronic hemodialysis.

n the literature, spontaneous quadriceps tendon ruptures are reported in patients with chronic renal failure. There are generally predisposing factors, such as unnoticed recurrent microtrauma or degenerative changes, in most cases. Conditions such as hyperparathyroidism and metabolic acidosis due to chronic renal failure may cause tendon degeneration.1–4 Immediate diagnosis of tendon rupture and differential diagnosis of partial or complete rupture is necessary for accurate diagnosis. Although partial ruptures rarely necessitate surgery, complete ruptures require surgery. Delayed diagnosis and the absence of appropriate treatment would cause prolonged disability, weakness of extensor mechanisms, and joint instability.5,6 Mehmet A.
