Quadriceps Tendon Rupture And Repair

What is quadriceps tendon rupture?

A tear in the quadriceps tendon normally occurs due to a traumatic injury. Naturally, the quadriceps tendon is made of sturdy fibrous tissue found at the top of the kneecap, which helps attach the kneecap to the quadriceps muscles. The quadriceps tendon works in conjunction with the quadriceps muscles to flex the leg.

The quadriceps tendon can tear partially or completely, depending on the severity of the injury. Fortunately, a partial tear does not affect the soft tissue entirely. However, a complete tear severs the soft tissue entirely. As a result, the quadriceps muscles will no longer connect to the kneecap.

With small ruptures, although you will experience pain, you will still be able to engage in activities and walk. Conversely, with a complete tear, you can anticipate severe pain and immobility, in which case you will require surgical repair to regain the function of your knee.

What causes quadriceps tendon rupture?

Quadriceps tendon rupture is a common injury affecting older people who engage in high-impact sports such as jumping or running. Alternatively, a tear in the quadriceps tendon can also occur due to a direct impact on the kneecap from an assault or vehicle accident.

What are the signs of quadriceps tendon rupture?

Signs of quadriceps tendon rupture include:

• A popping or displaced feeling
• Knee pain and swelling at the site of the tear
• Joint tenderness
• A kneecap that sags

How does Dr van Niekerk check for quadriceps tendon rupture?

In order to identify a partial or complete tear in the quadriceps tendon, Dr van Niekerk will inspect the knee and order an x-ray and MRI to reinforce the diagnosis. An x-ray provides a view of the current position of the knee, and an MRI evaluates the extent of the tear.

How do you treat quadriceps tendon rupture?

Treatment for quadriceps tendon rupture may be non-surgical or surgical, depending on how badly torn the quadriceps tendon is. A knee brace or other form of immobilisation helps hold the knee and surrounding structures in place to facilitate healing. Dr van Niekerk will recommend crutches so you do not place excessive load on the knee. Physical therapy helps improve flexibility and mobility of the joint after pain and swelling subside.

Surgery is advised when you suffer a complete tear of the quadriceps tendon. Dr van Niekerk performs surgery intending to reconnect the ruptured tendon to the kneecap.

In order to perform tendon repair, Dr van Niekerk creates an incision over the affected tendon in the knee. Next, he places sutures within the torn tendon, which he guides through holes made in the kneecap using a drill. Afterwards, he ties the sutures beneath the kneecap and stretches the torn pieces of the tendon in their original position.
