Know All About Patellar Tendon Tear Management

What is a Patellar Tendon Tear?

The patellar tendon, a robust, fibrous band of tissue, attaches the patella to the tibia, the shinbone. A direct impact to the knee or a quick, intense contraction of the quadriceps muscle can both cause a patellar tendon tear, which is a rupture or partial tear of this tendon.

Basketball players, sprinters, high jumpers, and other athletes who involve in frequent bending of the knees are at a higher risk of patellar tendon tear. Patellar tendon rips can also occur in people whose tendons are already weak from long-term conditions like diabetes or rheumatoid arthritis

What Can Cause a Patellar Tendon Tear?

The patellar tendon can be torn by a quick, jarring contraction of the quadriceps muscles or by a direct knee hit. Common causes of a patellar tendon tear include the following:

• In cases of overuse or recurrent trauma, the tendon may become weak and eventually rip.
• A sudden knee twist or turn while the foot is firmly planted on the ground.
• In the case of a fall or direct impact on the knee, the tendon may be torn
• Any long-term medical conditions, such as diabetes, high cholesterol, hyperparathyroidism or systemic lupus erythematosus (SLE), can weaken the patellar tendon and increase the risk of a tear.
• The use of certain drugs such as steroids, can weaken the tendon and make it more vulnerable to damage.
• An insufficient warm-up before exercise or a lackluster physical preparation.

Though patellar tendon tears are more frequently seen in athletes who play sports like basketball and volleyball that require jumping and landing they can also occur in non-athletes as well. Advancing age can also be a risk factor in patellar tendon tears as your tendons may undergo age-related wear and tear.

What are the Symptoms of a Patellar Tendon Tear?

You may feel a popping sensation when the injury occurs. Other symptoms following a torn patellar tendon may include the following:

• Weakness or instability of the knee joint
• Intense pain can be felt under the kneecap
• Bruising and soreness around the knee
• An indentation below the kneecap
• Difficulty in straightening your knee or  trouble walking

After a fall or other injury, if you notice any of these symptoms, make sure to visit your doctor without any delay. A severe injury like a torn patellar tendon may need surgery to be repaired.

How is a Patellar Tendon Tear Diagnosed?

A physical examination and imaging studies can be used to detect a patellar tendon tear. The doctor will begin by inquiring about the patient's symptoms and the history of any accident or fall. Additionally, they could conduct a physical examination to look for knee edema, discomfort, and limited range of motion.

To confirm the diagnosis your doctor may use the following imaging tests:

• X-Rays: Doctors might make use of X-Rays to examine the knee joint for any abnormalities or fractures.
• Ultrasound: This non-invasive examination produces internal images of the knee using high-frequency sound waves, enabling the physician to detect a tear and assess its severity.
• MRI (Magnetic Resonance Imaging): This test helps produce a sharper look at the tendon and the degree of the tear.
• CT scan: A CT (Computerised Tomography) combines a series of X-Ray images from different angles to get a detailed view of the joint.

The doctor may also conduct a knee arthroscopy in some situations, which entails inserting a tiny camera into the knee joint to view the injured tendon and determine the severity of the tear.

What are the Treatment Measures for a Patellar Tendon Tear?

The severity of the damage determines the course of treatment for a torn patellar tendon. While surgery may be required in some cases to heal the tendon, in others, conservative therapy may be advised.

Conservative treatments might involve the following:

• Rest: Avoid activities that hurt or endanger your knee.
• Ice: Ice is used to treat knee discomfort and edema.
• Compression: Wearing a compression sleeve or bandage to help with edema reduction.
• Elevation: To minimize swelling, elevate the injured leg.
• Physical therapy: Physical therapy under a certified therapist will help reduce pain and inflammation, restore range of motion, strengthen the muscles around the knee, and improve overall function and mobility.

Surgical repair of the patellar tendon may include the following steps:

• The surgeon makes a small incision in the skin over the knee joint to access the damaged tendon.
• Your doctor then carefully reattaches the torn ends of the patellar tendon using strong sutures or anchors. In some cases, a graft may be used to reinforce the repaired tendon.
• Once the tendon has been repaired, the surgeon closes the incision with stitches or staples.

Physical therapy sessions after the surgery can assist you to regain your range of motion, strength, and functionality. In order to achieve the greatest results after surgery, make sure you adhere to your doctor's instructions for post-operative care. Full recovery can take about a few weeks to 6 months.

What are the Complications of a Patellar Tendon Tear?

If a patellar tendon tear is not detected early or treated right away, complications may result. A few of the potential issues are as follows:

• Chronic knee pain: Some people may feel knee pain or discomfort even after treatment.
• Knee stiffness: The knee joint may become stiff and difficult to move, which can limit mobility and affect overall function.
• Instability in the knee: A significant tendon tear may cause instability in the knee, making it difficult to stand, walk, or engage in other physical activities.
• Arthritis of the knee: In some situations, a torn patellar tendon can cause arthritis to form in the knee joint.
• Infection: Surgery to repair the patellar tendon occasionally leaves patients with an infection that may need extra care.
• Re-injury: The patellar tendon is susceptible to re-injury in the absence of appropriate rehabilitation and preventative measures.

If you notice any signs of a patellar tendon tear, you should consult a doctor right once to avoid any potential problems and to ensure the best possible outcome.

How to Prevent Patellar Tendon Tears?

Some measures to prevent patellar tendon tears may include:

• Strengthen your leg muscles: Building strong leg muscles, such as the quadriceps, hamstrings and calf muscles can assist support to the knee joint and lower the risk of injury. Regular exercise and strength training can help you achieve this.
• Warm up and stretch before exercise: Always spend time warming up and stretching your muscles before starting any physical activity or exercise.
• Choose appropriate footwear: When jogging or engaging in sports, choose appropriate footwear with sufficient support and cushioning.
• Avoid making abrupt changes to your activity: Making abrupt changes to your activity's intensity or duration can raise your risk of injury. 
• Maintain a healthy weight: Being overweight puts more strain on your knees and raises your chance of injury.
• Avoid overusing your knees: Overusing your knees, particularly when engaging in repetitive motions like jogging or leaping might increase your risk of injury. Include days off from exercising in your weekly schedule.
• Treat knee problems promptly: Immediately seek medical assistance if you have any knee pain, swelling, or discomfort to prevent further injury.
