Tendon Injuries: Causes, Symptoms, and Effective Treatments

Tendon injuries are a common issue affecting people of all ages, particularly those with active lifestyles. From athletes to individuals with physically demanding jobs, tendon injuries can lead to pain, reduced mobility, and interruptions in daily activities. This comprehensive guide explores everything you need to know about tendon injuries, from their causes and symptoms to effective treatments and prevention methods. 

Recognising the early signs of an overuse injury and understanding your treatment choices to avoid injury, here is your complete guide to common tendon injuries. However, if you think you may suffering from a tendon injury, it is advised to consult an orthopaedic specialist at the earliest.

What Is a Tendon?

Tendons are fibrous cords that connect your muscles to bones and transmit the force that allows you to move your joints. Each one of your tendons is made up of collagen, a rigid kind of protein that is connected in strands that run parallel to the natural direction of force in your body. When you use your muscle, it pulls on your tendon. This movement of your tendon transfers force to your bone and causes your joint to move. These internal transfers of power all happen in a fraction of a second. 

While we rarely think about them, our tendons are actually a remarkable body part that can withstand high levels of force while staying flexible and agile. They work like strong, flexible cables connecting your muscles to your skeletal system. Without healthy tendons, it would be impossible to walk, run, jump or lift anything. These connective tissues are vital for posture and movement.

Where Are Tendons Located?

There are tendons throughout your body that attach your muscles to your bones. Here are some of the major tendon locations:

• The Achilles tendon attaches your calf muscles to the heel bone 
• Patellar tendon connects your kneecap to the shinbone
• The Quadriceps tendon connects your thigh muscles to the kneecap 
• Hamstring tendons attach the back of your thigh to your lower leg
• Rotator cuff tendons connect your shoulder muscles to your upper arm
• The biceps tendon attaches your biceps muscle to your shoulder and elbow
• The triceps tendon connects your triceps muscle to your elbow
• Forearm extensor tendons attach the muscles to the back of your hand
• Forearm flexor tendons attach the muscles to the palm side of your hand
• Finger flexor tendons allow you to bend your finger joints
• The abductor pollicis longus tendon bends your thumb 
• Extensor pollicis longus tendon straightens your thumb
• Peroneal tendons stabilise your outer ankle and foot
• The tibialis posterior tendon supports the arch on your inner ankle
• Adductor tendons attach your inner thigh muscles to the bone
• IT band connects your outer hip muscles to your knee 
• Popliteus tendon unlocks your knee joint

What Are Tendon Injuries?

Tendon injuries occur when the strong, fibrous tissues that connect muscles to bones are strained, inflamed, or torn due to overuse, trauma, or underlying health conditions. The most common tendon injuries include tendinitis, tendinosis, and ruptures.

Common Causes of Tendon Injuries

Tendon injuries can result from a variety of factors. Understanding the causes can help you prevent them:

1. Overuse: Repeated stress on tendons during activities like running, jumping, or lifting heavy weights can lead to micro-tears and inflammation.
2. Trauma: Direct injuries, such as falls or sudden impacts, can damage tendons.
3. Aging: Tendons lose elasticity and strength with age, making them more prone to injury.
4. Sports or Physical Activity: Activities that involve repetitive motion or sudden bursts of energy (e.g., tennis, basketball) increase the risk.
5. Medical Conditions: Diseases like diabetes, rheumatoid arthritis, or gout can weaken tendons.
6. Improper Technique: Incorrect posture or movement during physical activity can place unnecessary stress on tendons.

Common Symptoms of Tendon Injuries

Tendon injuries often present with a variety of symptoms, depending on the severity and location of the injury. Common signs include:

• Pain: Typically sharp or aching pain around the affected tendon, especially during movement.
• Swelling: The injured area may become swollen, tender, and warm to the touch.
• Stiffness: Reduced range of motion, especially after periods of inactivity.
• Weakness: Difficulty performing regular tasks that involve the affected tendon.
• Visible Changes: In severe cases, tendon tears may cause deformities or gaps under the skin.

Risk Factors for a Tendon Injury

Following are some of the major risk factors that can predispose someone to a tendon injury:

• Age: Tendons lose strength and elasticity as you get older and this increases your risk of tears and ruptures.
• Prior injury: Previous damage to your tendon can weaken it and make it more prone to re-injury.
• Overuse: Repetitive strain from certain sports, jobs, and everyday activities can irritate your tendons over time.
• Medical conditions: Diabetes, arthritis, hyperparathyroidism, and autoimmune diseases make tendon damage more likely.
• Nutrition: Diets lacking in protein and vitamin C can affect your tendon health.
• Genetics: Variations in collagen production can cause a predisposition to tendon abnormalities.

Being aware of these risk factors can help you to make the necessary changes to your training, technique, equipment, environment, and lifestyle to help avoid tendon injury. 

Types of Tendon Injuries

Tendon injuries can broadly be divided into the following categories:

1. Tendinitis

• Inflammation of the tendon, often caused by overuse.
• Common types: Achilles tendinitis, tennis elbow, and rotator cuff tendinitis.

2. Tendinosis

• Chronic degeneration of the tendon without significant inflammation.
• Typically caused by prolonged overuse and inadequate healing.

3. Tendon Ruptures

• Complete tear of a tendon, leading to severe pain and loss of function.
• Common examples include Achilles tendon rupture and biceps tendon rupture.

How Are Tendon Injuries Diagnosed in Singapore?

If you suspect a tendon injury, consulting a healthcare professional is crucial. Your doctor will carry out a series of tests as part of the diagnosis, which typically involves:

1. Medical History and Physical Exam: The doctor will review your symptoms, activity history, and perform a physical examination.
2. Imaging Tests: The doctor may order any of the following diagnostic imaging tests to further aid in the diagnosis process.These can include:
   • Ultrasound: To visualise soft tissue structures and detect inflammation or tears.
   • MRI: Provides detailed images of tendons and surrounding tissues.
   • X-Ray: Used to rule out fractures or other bone-related issues.

Treatment Options for Tendon Injuries

The right treatment for your torn or injured tendon depends on different factors like the severity of the tear, its location, your health background, and your general activity level. In all cases, the first steps are always non-surgical. Lifestyle adjustments and non-invasive measures can typically treat minor to moderate injuries. Here are a few common treatments for an injury to a tendon.

Non-Surgical Treatments

1. Rest and Immobilisation: Avoiding activities that stress the tendon allows for healing.
2. Ice and Compression: Reduces swelling and alleviates pain in the affected area.
3. Physical Therapy:
   • Strengthening exercises to improve tendon resilience.
   • Stretching to restore flexibility.
4. Medications: Over-the-counter pain relievers like ibuprofen or aspirin help manage pain and inflammation. You can also take tendon health supplements to improve collagen production and strengthen the tendons.  
5. Topical Gels and Creams: Topical gels and creams can also be used to alleviate pain from inflamed tendons.
6. Advanced Therapies:
   • Platelet-Rich Plasma (PRP): Speeds up healing by injecting platelets into the injured tendon.
   • Shockwave Therapy: Stimulates tendon repair using sound waves.

Surgical Treatment for Tendon Injuries

When non-invasive treatment does not seem to be effective for your tendon injury, your doctor may recommend surgery to repair the damage and restore normal function.

• Tendon Repair Surgery: Tendon repair is carried out for severe tears or ruptures. The operation can be performed either arthroscopically through several small incisions or as open surgery with one larger incision exposing the full tendon. During the operation, your surgeon will determine the location of the tear and remove any frayed or degenerated tendon tissue. The ends of the tendon will be reconnected if needed.
• Tendon Transfer or Grafts: This surgery is used when the original tendon cannot be repaired. During this procedure, a healthy tendon from some other part of the body is used to replace the injured tendon.
• Post-surgery rehabilitation is essential to restore mobility and strength. After surgery, your joint will be immobilised in a splint or cast for two to six weeks. After about a month, the specialist will get you started with physical therapy to gradually restore your flexibility, strength, and motion.

Healing Time After Surgery for a Tendon Injury

While each person may have a different experience, there are some general timelines for healing and recovery after tendon surgery.

• Minor tendon repair: For a small tear or laceration, you can expect immobilisation with a splint or cast for four to six weeks. After that, you can gradually return to activity over several weeks. The full recovery time typically takes three to four months.
• Major tendon repair: For a large tear or rupture, you may be immobilised for six to eight weeks. This will be followed by gradual physical therapy to improve your strength and range of motion over the course of several months. Full recovery can take 6 months to one year.
• Tendon transfer or reconstruction: In this case, you can expect immobilisation for six to eight weeks, followed up by up to a year of physical therapy for full recovery.
• Tendon release or lengthening: Your doctor will recommend Immobilisation for two to four weeks, then gentle stretching and strengthening. You can typically return to normal activity in six to 12 weeks.

It is essential to keep in mind that the exact timeline will depend on the location and severity of your tendon injury, as well as the surgical approach. Your age and overall health will have a major impact too so it is important to not rush your recovery. Trying to rush back too soon increases your risk of reinjury or complications. 

Preventing Tendon Injuries: Tips for Everyday Life

There are certain measures that you can take to prevent tendon injuries, such as:

1. Warm Up and Cool Down: Always prepare your muscles and tendons before and after physical activity.
2. Maintain Proper Technique: Use correct posture and form during sports or exercise.
3. Strengthen Supporting Muscles: Build strength in muscles around major tendons to reduce stress.
4. Gradual Progression: Avoid sudden increases in intensity or duration of activities.
5. Use Supportive Equipment: Proper footwear and ergonomic tools can reduce strain.
6. Take Breaks: Give your body time to recover between intense activities.

When to See a Specialist in Singapore for Tendon Injuries

It is important to seek medical attention if:

• Pain persists or worsens despite rest and basic treatment.
• You notice significant swelling, deformity, or bruising.
• You experience sudden, severe pain during activity, which could indicate a rupture.
• Your mobility or strength in the affected area is severely reduced.
