Reconstruction of Acute Patellar Tendon Rupture after Patellectomy

Abstract EN

Acute rupture of the knee extensor mechanism after patellectomy is extremely rare.

We present the case of a patient with acute patellar tendon rupture who had undergone patellectomy 53 years before.

Twelve days after the injury, the ruptured patellar tendon was repaired with end-to-end suture.

Postoperatively, we splinted the knee for 6 weeks but permitted the patient to walk without limiting weight bearing at 1 week postoperatively.

At one-year follow-up, the patient is able to move his knee almost full range of motion and the Lysholm knee score is 81.

The patient is satisfied with the outcome.

This is the first report to treat acute rupture of the patellar tendon in a patient who had undergone patellectomy.

Although careful rehabilitation is required, end-to-end suture might be an adequate surgical procedure for acute rupture of the knee extensor mechanism after patellectomy.
