Quadriceps Tendon Repair

What is Quadriceps Tendon Repair?

Quadriceps tendon repair is a surgical procedure where an orthopedic surgeon reconnects the quadriceps tendon, which attaches the large thigh muscle to the top of the kneecap (patella), back to the bone. There are two primary methods used to achieve this:

• Patellar Transosseous Tunnel Repair: Drilling vertical tunnels through the kneecap (patella) from top to bottom to thread sutures and tie the quad tendon down.
• Superior Patellar Anchor Technique: Placing suture anchors directly into the upper pole of the kneecap to reattach the quadriceps tendon without drilling through the entire bone.

Your surgeon will evaluate your specific injury to determine which method is most appropriate for your recovery.

Who Should Have a Quadriceps Tendon Repair?

Surgery is not always necessary for every injury; individuals with partial or very small tears can often recover without an operation. In these cases, a combination of knee immobilization in a straight brace and targeted physical therapy is usually sufficient. However, because complete tears cause a loss of the straight-leg raise and prevent you from supporting your own weight, most patients with full ruptures require quadriceps tendon repair surgery to fully restore the extension, strength, and stability of the knee.

How Well Does Quadriceps Tendon Repair Work?

The success rate for this procedure is high, with most patients regaining between 85% and 90%+ of their original leg strength and full joint function. To track your progress, your surgeon will compare the strength and extension of the injured leg against your healthy leg, providing a clear benchmark for your recovery.

A critical factor in the outcome of the surgery is the precision with which the surgeon reattaches and sets the tension of the repair. Because of this, it is highly recommended to partner with an experienced provider who performs these procedures frequently, such as the specialists at Fox Valley Orthopedics.

While some patients may experience temporary stiffness or mild weakness following surgery, these issues are typically short-lived. As with any surgical intervention, there are general risks including anesthesia complications, nerve irritation, blood clots, or infection. At Fox Valley Orthopedics, we pride ourselves on maintaining very low complication rates.

What Can I Expect When I Have a Quadriceps Tendon Repair?

Depending on your medical history, you may be required to complete a pre-surgical physical to ensure all necessary health accommodations are in place. Upon arriving at the surgical facility, you will consult with your anesthesiologist and surgeon. Depending on your needs, you will receive either general anesthesia or regional nerve blocks. During the procedure, you will be positioned face up to allow the surgeon full access to the front of the knee. Depending on your overall health and the specifics of the case, you will typically be discharged the same day to recover at home.

Following surgery, your doctor will provide a plan for pain management and icing, which typically lasts about a week. To protect the surgical repair, your leg will be immobilized in a hinged knee brace locked straight, and you will use crutches or a walker to restrict weight-bearing for approximately 4 to 6 weeks.

Once this initial healing phase is complete, you and your physical therapist will follow a guided rehabilitation plan designed to safely restore movement and rebuild leg strength. The timeline for a full recovery and return to full activities or sports generally ranges from 6 to 12 months.
