Quadriceps Tendon Injuries Treatment Options

Can a quadriceps tendon rupture be treated without surgery?

In some cases, a partial rupture of the quadriceps tendon may be treated non-surgically with rest, immobilization using a hinged knee brace locked straight, and physical therapy. A platelet rich plasma (PRP) injection directly to the affected tendon can also help relieve knee pain and promote healing of the partial thickness tearing of the tendon. Moreover, extracorporeal shock wave treatments have also been shown to produce good outcomes.

However, it is important to note that complete quadriceps tendon ruptures often require surgical repair to regain full knee function. Additionally, even in cases of a partial quadriceps tendon rupture, if you cannot perform a straight leg raise, surgical intervention will likely be recommended.

What are the surgical options for a quadriceps tendon rupture?

Surgical options for quadriceps tendon ruptures typically involve reattaching the torn quadriceps tendon to the patella using sutures or non-metal anchors. The choice of surgical technique depends on the extent and location of the injury.

In cases of more severe injury or chronic injury to the quadriceps tendon, Dr. Chahla may recommend reconstructing the quadriceps tendon using either an Achilles tendon allograft (donor tissue) or a biologics patch known as Regeneten. Regeneten is a collagen-based implant that supports the body’s natural healing response to facilitate new tendon-like growth and mitigate strain at the site of the quadriceps tendon tear. Regeneten is composed of Type 1 collagen and has been observed for up to 5 years to increase and sustain the repaired quadriceps tendon thickness.
