Patellar Tendon Repair

The patellar tendon connects the kneecap (patella) to the shinbone (tibia) and plays an essential role in straightening the knee and maintaining normal leg function. A patellar tendon tear is a serious injury that can occur due to sports activities, sudden forceful movements, or direct trauma. When the tendon completely ruptures, surgical repair is often needed to restore proper knee stability, strength, and movement. At Allyson Estess, MD, patellar tendon repair is performed using advanced surgical techniques designed to restore the tendon’s connection and support long-term recovery. Each treatment plan is personalized based on the severity of the injury, activity level, and recovery goals. With expert surgical care and a structured rehabilitation program, patients can work toward regaining strength, mobility, and confidence in their knee.

What is a patellar tendon repair?

Patellar tendon repair is a surgical procedure used to reconnect a torn patellar tendon to the kneecap or shinbone. The repair restores the function of the extensor mechanism, which allows you to straighten your knee, walk normally, and perform everyday movements.

This procedure is typically recommended for complete tendon ruptures or severe injuries where the tendon has separated from its attachment point. Early diagnosis and treatment are important to achieve the best possible outcome and prevent long-term weakness.

Frequently Asked Questions

What causes a patellar tendon tear?

Patellar tendon tears commonly occur when a strong force is placed on the knee while the quadriceps muscle contracts. This can happen during jumping, running, sports injuries, falls, or sudden movements that place excessive stress on the tendon.

Certain factors, including previous tendon injuries, chronic inflammation, or conditions affecting tendon strength, may increase the risk of a tear. Your orthopedic specialist will evaluate the injury and recommend the most appropriate treatment approach.

What are the symptoms of a torn patellar tendon?

A torn patellar tendon often causes sudden pain in the front of the knee, swelling, and difficulty straightening the leg or walking. Some patients may feel or hear a popping sensation at the time of injury and notice weakness when attempting to extend the knee.

A physical examination and imaging studies, such as X-rays or MRI, help determine the severity of the injury and confirm whether surgical repair is needed.

How long does recovery take after patellar tendon repair?

Recovery after patellar tendon repair varies depending on the severity of the tear and individual healing progress. Initially, the knee is protected with a brace, and movement is gradually increased according to your surgeon’s rehabilitation protocol.

Physical therapy is an important part of recovery and focuses on restoring range of motion, rebuilding strength, improving balance, and returning to normal activities. Many patients continue progressing for several months before regaining full strength and function.

What are the benefits of patellar tendon repair?

Surgical repair helps restore the connection between the kneecap and shinbone, allowing the knee to regain stability and strength. Without treatment, a complete patellar tendon rupture can lead to difficulty walking, reduced knee function, and long-term limitations.

With timely surgical care and a dedicated rehabilitation program, many patients achieve significant improvements in mobility and strength. The goal of repair is to help you return to daily activities, work, and recreational pursuits safely.
