Lifestyle: Pushing forward to recovery

Lifestyle: The long and winding road

As my injury heals, I am understanding and respecting how the body reacts to trauma. *The good news is it’s getting better all the time. Learning to use only one crutch instead of two, trying to maneuver up and down stairs, ( that’s still going to take some time) getting increased range of motion in the injured leg, (up to 94 degrees, should be 135) and moving somewhat better.

  • Still to come in no particular order: driving, walking without a brace or crutches, getting stronger leg muscles, building up endurance and eventually get back to work. No timetable but it’s heading in the right direction.
  • What I learned is serious injuries and surgeries take more time than I thought and was totally unrealistic in how long recovery is. You get what you need.

Patellar tendon rupture

By Bryson P. Lesniak, MD and Asheesh Bedi, MD

Patellar tendon rupture is a rupture of the tendon that connects the patella to the tibia.  The patellar tendon is the terminal extension of the quadriceps muscle in the leg. The four muscles that make up the quadriceps each provide a tendon that attaches to the kneecap (patella). The patella essentially lies within the quadriceps tendon and is therefore called a “sesamoid” bone. The quadriceps tendon becomes thicker and narrower as it travels from the kneecap to the shin bone (tibia). This thicker and somewhat narrower tendon is called the patellar tendon because it starts at the patella and ends at the tibia.

Are any athletes specifically at risk for a patellar tendon rupture? 
The patellar tendon is instrumental in allowing a person to straighten his/her leg. When the quadriceps contracts the force is transmitted through the quadriceps tendon and the patellar tendon, using the patella as a fulcrum and thus straightening the leg. If any link in this chain is disrupted- whether through a quadriceps tendon rupture or the patellar tendon rupture, a patella fracture or inability to contract the quadriceps muscle- the leg cannot extend at the knee. Keith Grennan of the Cleveland Browns, Cadillac Williams of the Tampa Bay Buccaneers, Kelenna Azubuike of the Golden State Warriors, and Correll Buckhalter of the Denver Broncos have all suffered from a patellar tendon rupture. 

A patellar tendon rupture tends to occur in people age 40 and younger. After the approximate age of 40 years, the quadriceps tendon becomes the more common tear in the extensor mechanism. Any condition that affects the quality or integrity of tendons or ligaments increases the risk of rupture; for example, diabetics and patients who take corticosteroids for an extended period of time for diseases like systemic lupus or rheumatoid arthritis. A growing population at risk is athletes that take anabolic steroids to increase their performance. Steroids can weaken the tendon and increase the risk of their rupture. 

Patellar tendon rupture symptoms. How is it diagnosed?

An athlete that has a patellar tendon rupture has immediate pain and swelling in the knee area. He or she will often say they felt a “rip” or “tear” sensation and will be unable to ambulate because of weakness and pain. On examination there are several tell-tale features in addition to pain and swelling in the knee. First, the athlete will be unable to actively straighten the leg. In addition, the examiner can usually palpate a defect in the tendon below the kneecap. However, in some cases the swelling in the knee joint (knee effusion) is severe enough that this is difficult to appreciate. The knee effusion in combination with severe pain with motion often requires radiologic examination to assist in making the diagnosis.

Are any imaging studies utilized in diagnosing the patellar tendon rupture?

Knee X-rays are the first imaging studies that are obtained and can be very helpful. When the patellar tendon ruptures, the patella shifts superiorly because of muscle contraction of the quadriceps muscles. This shift in the patella position is called “patella alta.” X-rays also evaluate the knee for any other injuries that can present similarly to a patellar tendon rupture such as a fracture. If any doubt remains after physical examination and X-rays, an ultrasound or magnetic resonance imaging (MRI) can be performed.

Ultrasonography is a safe, inexpensive and rapid test that can detect a tendon tear. However, the test is technician dependent and in some facilities is not a reliable diagnostic test. MRI is also a safe test but is more expensive and takes longer to perform. In addition, availability of MRI’s can be limited in emergency rooms and a doctor’s office. However, an MRI can also evaluate any other potential problems in the knee such as ligament or cartilage injury. In the vast majority of athletes who have suffered a patellar tendon rupture, an MRI is not indicated as the diagnosis is made with X-rays and physical examination. However, in the case of partial tears, chronic tears or an unusual presentation, an MRI can be a useful diagnostic tool.

How does a patellar tendon rupture occur? 

It is generally accepted that healthy, “normal” patellar tendons do not rupture. That is, there is an underlying degeneration in the tendon prior to complete rupture. The usual circumstance surrounding a patellar tendon rupture is when a person suddenly contracts the quadriceps muscle when the knee is in a flexed position. A common example is running up a flight of stairs or when a running back stops running quickly to change direction.

Patellar tendon rupture treatment

For an athlete, surgical repair of the torn tendon is recommended. If the tear is treated nonoperatively, athletes rarely have the ability to extend the leg and ambulate normally without assistance. Surgical repair, while not an emergency, should be performed soon after the injury occurred. This allows for an easier repair before a significant accumulation of scar tissue. Most surgeons perform a direct repair of the tendon if it is torn in the middle. If the tendon is torn off of the bone, several different techniques can be utilized such as reattaching the tendon to the bone with a combination of sutures and bone tunnels. Regardless of technique, the goal of surgical repair is to re-approximate the tendon ends in a secure fashion to allow it to heal.

If the patellar tendon is not repaired soon after the injury (within 5-6 weeks), surgical repair can become more difficult and have suboptimal results. If the tendon cannot be repaired back to itself, a reconstruction can be performed with a graft from donor tissue (allograft) or tissue taken from another part of the patient’s body (autograft).

Patellar tendon rupture recovery time?

Patellar tendon rupture recovery time after surgery varies based on surgeon preferences.  After surgery, athletes are placed in a knee brace that keeps their knee straight. Most rehabilitation plans allow initiation of active knee flexion and passive extension by two weeks after surgery. At 6 weeks after surgery, athletes can walk without crutches.  The stiffness that comes with the patellar tendon recovery, combined with muscle atrophy creates problems for athletes who need to place significant load through their knee.  So early motion combined with early muscle activation is very important. Usually, a return to athletic activities is delayed until 4-6 months after surgery based on leg strength and range of motion. The rehabilitation for chronic reconstructions is more substantial and prolonged than above.

What are the results of surgical repair?

If the repair is done acutely (within 3 weeks), most athletes report good or excellent results. Most athletes are able to return to their previous level of competition and do not report residual weakness or discomfort. The results with repairs done after 3 weeks are not as favorable because of persistent weakness or poor range of motion as the likely cause of disability.

Are there any complications associated with the surgery? 

Loss of knee motion and quadriceps weakness are the two most common problems after surgery. Whether this is due to the initial injury or the surgical repair is difficult to determine, but likely due to the initial injury. With postoperative physical therapy as discussed above, the goal is to minimize these problems. Less common complications include persistent knee effusion, infection, and re-rupture of the repaired tendon.
