What is Tendinosis?
Tendon injuries can affect a wide array of people, from athletes to non-athletic individuals. Certain sports and jobs increase the risk of specific tendon injuries. The terminology and definitions of tendon injuries have significantly evolved over the past 40 years.
‘Tendinopathy’ is a general term used to describe pain in the tendon without being sure about the exact cause, which could include tears, inflammation at the point where the tendon attaches to the bone (enthesitis) or long-term wear and tear (degeneration). In the past, tendon pain along with reduced function was often referred to as ‘tendinitis’.
‘Tendinitis’ indicates an injury to the tendon along with inflammation – a situation commonly found in a condition called spondyloarthritis. However, when comparing healthy tendons with injured (or symptomatic) ones in various microscopic tissue studies, it was found that these injured tendons appeared to be more worn out or degraded, showing very few or no signs of inflammation. Because of this, ‘tendinosis’ is actually a more accurate term to describe the process.
What Causes Tendinosis?
Doctors aren’t completely sure what causes tendinosis, but they think it might start with an injury that leads to damage and inflammation. The injury could be from things like mechanical stress on the tendon, using the tendon too much without enough rest, or harmful chemicals. Some people might be more likely to get tendinosis because of things like their age, genetics, or other health conditions. These factors can make it harder for their body to heal, which could lead to tendinosis.
Risk Factors and Frequency for Tendinosis
There isn’t a lot of research on tendinosis, a type of tendon disorder. This may be because people often treat themselves or it’s improperly recorded or categorized in medical records.
Signs and Symptoms of Tendinosis
When a patient comes in with a possible tendon injury, it’s important for the medical professional to understand the patient’s recent activities and lifestyle. They need to know if the patient has lately started a new workout routine, taken on work duties that put more strain on their body, or started new medications. These factors can all contribute to tendon damage. The health professional would also want to understand how much the injury is affecting the patient’s daily life, which will help them plan the best treatment.
After gathering this information, a physical exam is done to evaluate the condition of the tendon. Special tests might be needed for detailed evaluation, depending on which tendon is involved. Usually, the diagnosis of tendinosis is made based on the patient’s history and the results of the physical exam. If necessary, additional tests might be arranged to get a clearer picture of the injury.
Testing for Tendinosis
If your doctor is unsure about what’s causing tendinosis (a condition that weakens and damages your tendons) after examining you and talking to you about your symptoms, they might ask for laboratory tests to be done. This could include tests for C-reactive protein and ESR (Erythrocyte Sedimentation Rate). These tests aren’t very specific, but they can help the doctor see if there’s any inflammation going on in your body – like what happens in a condition called spondyloarthritis.
Your doctor might also ask for X-rays if they think you might have an injury to a bone. Additionally, ultrasound machines are often used in these cases. Ultrasounds can help guide some treatments for tendinosis, and its use is becoming more common. However, the results can vary depending on who is performing the ultrasound and which tendon they’re looking at. Different parts of the body might also require different settings for the best image quality on the ultrasound.
Common things that a doctor might see on an ultrasound when someone has tendinosis include increased spaces between the bright white lines in the tendon, decreased brightness of the tendon, thickening of the tendon, and new blood vessels appearing (seen with a technique called color Doppler).
An MRI (Magnetic Resonance Imaging) can also be helpful when a doctor is evaluating tendinosis. An MRI can provide detailed images of the tendons and surrounding areas, offering additional insights into the condition.
Treatment Options for Tendinosis
The first step to treating tendinosis, a condition where your tendons degenerate or wear down, usually includes a combination of rest, ice therapy, and specialized exercises guided by a physical therapist or occupational therapist.
There’s a lot of discussion regarding the effectiveness and role of NSAIDs (nonsteroidal anti-inflammatory drugs), that is, common pain relievers, in managing tendinosis. Some studies even suggest that these drugs may be harmful. That’s why there’s no clear guideline at the moment on whether or not to use these drugs in treating tendinosis.
In the past, steroid injections were often used to treat this condition. While they can relieve pain in the short term, research now shows that they can actually lead to worse health outcomes in the long run. That’s why these injections are no longer considered the main treatment option.
Most people with tendinosis due to overuse of their tendons tend to recover in between 3 to 6 months. However, if conventional treatment methods don’t work for some patients, we do have other options available.
Some of these unconventional options target the excessive growth of new blood vessels associated with tendinosis. Treatments like high-volume guided injections (injecting a large volume of solution), percutaneous needle tenotomy (breaking down the injured tendon using a needle), sclerosis (hardening of tissues), and percutaneous needle scraping (removing tissues using a needle) work by disrupting these new blood vessels.
Other alternatives include patches containing glyceryl trinitrate (a medication used to treat angina or chest pain), percutaneous ultrasonic tenotomy (using ultrasound energy to break down the injured tendon), and orthobiologics (natural substances like platelet-rich plasma and stem cells that help heal injuries).
If all else fails, a minor surgical procedure to release the tendon or a full surgery is considered as the last line of treatment.
What else can Tendinosis be?
When diagnosing tendonitis, doctors may consider other health conditions that can cause similar symptoms. These conditions include:
- Acute compartment syndrome
- Ankle injury
- Bursitis
- Carpal tunnel syndrome
- Gout and pseudogout
- Hand infections
- Reactive arthritis
- Rheumatoid arthritis
- Rotator cuff injuries
- Soft tissue knee injury
Your doctor will review these possibilities carefully to make sure they diagnose your condition accurately.
What to expect with Tendinosis
Tendons, which are the tough fibers that connect your muscles to your bones, may take a longer time to heal as they don’t have a lot of blood flow. Recovery from tendinosis, a condition characterized by chronic, sustained injury to the tendon, usually lasts from three to six months. Nonetheless, this healing time frame can be improved by treatments such as physical therapy, sufficient rest, and the appropriate medication.
If tendinosis is not addressed, it may lead to a severe complication known as a tendon rupture. This is when your tendon completely or partially tears, which can significantly disrupt your mobility and necessitate immediate treatment, possibly through surgery.
Possible Complications When Diagnosed with Tendinosis
Problems associated with tendinosis can be quite severe. Here is a list of possible complications:
- Tendon contractures, leading to less flexible tendons
- Tendon sticking to other tissues, also known as adhesions
- Muscle loss, or atrophy
- Impaired function, to the extent of disability
Preventing Tendinosis
Patients need to recognize the motion or activity that resulted in their current health issue and take a break from it for a certain amount of time. It’s also crucial that they follow the doctor’s instructions regarding medication and therapy.
As their condition starts to get better, patients need to make sure they warm up before starting any form of exercise. Avoiding doing the same movements over and over at work is important and they should avoid sitting down for too long; it’s a good idea to stand up and move around frequently throughout the day. Working on strengthening their muscles and improving their overall fitness level can also help prevent tendon damage (tendinosis).
