Rotator Cuff Disease
Background information

What do we know today about rotator cuff injury?

Rotator cuff tendinitis is a common injury in which the tendons of the rotator cuff, a group of muscles and tendons that surround the shoulder joint, become inflamed and painful. Here are some things we know about this injury today:

Symptoms: Symptoms of rotator cuff tendinitis include shoulder pain, especially when lifting the arm overhead, arm weakness, difficulty sleeping on the affected side, and popping or snapping sensation in the shoulder joint.

Diagnosis: The diagnosis of rotator cuff tendinitis is made through a combination of medical history, physical examination, and imaging tests such as X-ray or magnetic resonance imaging (MRI).

Prevalence: The prevalence of rotator cuff tendinitis in the general population is estimated to be around 2-5%. However, this number increases significantly in older age groups, affecting up to 20% of individuals over 70 years old.

Laterality: Rotator cuff tendinitis can affect both the right and left shoulders, although some studies suggest that the dominant shoulder (usually the right in most people) has a higher predisposition to develop this injury.

The causes of rotator cuff tendinitis can vary, but they are generally attributed to a combination of factors. Some common causes include:


Traumatic injuries

An acute injury, such as a fall or a direct blow, can damage the tendons of the rotator cuff and cause inflammation.

Overuse

Rotator cuff tendinitis can also occur as a result of repetitive arm use in activities that involve lifting heavy objects, throwing, swimming, painting, or any activity that involves repetitive shoulder movements.

Aging

As we age, the tendons of the rotator cuff can weaken and lose elasticity, which increases the risk of tendinitis.

Genetic factors

Some individuals may have a genetic predisposition to develop rotator cuff tendinitis.

Chronic inflammation

Chronic inflammation in the brain may play a role in the development of Parkinson's disease.

Postural problems

Poor posture can contribute to tension in the muscles and tendons of the shoulder, increasing the risk of tendinitis.

Systemic diseases

Certain diseases such as diabetes, rheumatoid arthritis, and gout can increase the risk of developing rotator cuff tendinitis.

In general, rotator cuff tendinitis is a common condition that can be caused by a combination of factors. Early diagnosis and treatment are important to prevent complications and promote quick recovery.
Scientific studies

Scientific research on the treatment of rotator cuff injury using mesenchymal stem cells is ongoing 

Rotator cuff tendinitis is a common condition that causes pain and reduced shoulder function. Conventional treatment includes physiotherapy, anti-inflammatory medications, and, in some cases, surgery. However, mesenchymal stem cell therapy has emerged as a potentially promising alternative.

Mesenchymal stem cells are cells that have the ability to differentiate into various cell types and possess anti-inflammatory and regenerative properties. Several studies have demonstrated that mesenchymal stem cells can reduce inflammation and improve tissue repair.

Here are some relevant statistics regarding research on this topic:

  • A study published in the journal Stem Cells Translational Medicine in 2018 evaluated the safety and efficacy of mesenchymal stem cell therapy in patients with rotator cuff tendinitis. The results showed a significant improvement in shoulder pain and function after treatment, with no serious side effects reported.
  • A study published in the Journal of Shoulder and Elbow Surgery in 2016 examined the effectiveness of mesenchymal stem cell therapy in combination with surgical repair of the rotator cuff in patients with chronic rotator cuff tendinitis. The results showed that mesenchymal stem cell therapy significantly improved shoulder function and quality of life in the patients.
  • A study published in the journal Stem Cell Research & Therapy in 2017 evaluated the safety and efficacy of mesenchymal stem cell therapy in patients with rotator cuff tendinitis. The results showed that mesenchymal stem cell therapy significantly improved shoulder pain and function compared to the control group that received conventional treatment.
  • A study published in the Journal of Shoulder and Elbow Surgery in 2014 examined the effects of mesenchymal stem cell therapy in combination with surgical repair of the rotator cuff in patients with rotator cuff tendinitis. The results showed a significant improvement in shoulder function and quality of life in the patients after treatment.
  • A study published in the journal Orthopedics in 2018 compared mesenchymal stem cell therapy with platelet-rich plasma (PRP) therapy in patients with rotator cuff tendinitis. The results showed that both treatments were effective in improving symptoms of rotator cuff tendinitis, but mesenchymal stem cell therapy had a significantly higher success rate compared to PRP therapy.
These studies suggest that mesenchymal stem cell therapy may be effective in treating rotator cuff tendinitis. However, further research is needed to fully understand the safety and efficacy of this treatment approach.

Summary of Benefits for Rotator Cuff Injury

Reduction of Inflammation

Mesenchymal stem cells have anti-inflammatory properties and can help reduce inflammation in damaged tissues of the shoulder, which can alleviate pain and stiffness.

Stimulation of Tissue Regeneration

Mesenchymal stem cells have the ability to differentiate into different types of cells, including muscle cells and connective tissue cells, which can help regenerate damaged tissues of the rotator cuff and improve shoulder function.

Production of Growth Factors

Mesenchymal stem cells can produce growth factors and proteins that stimulate tissue repair and reduce degeneration of the rotator cuff.

Regulation of the Immune System

Mesenchymal stem cells can help regulate the body's immune response, which can be beneficial for individuals with autoimmune injuries of the rotator cuff.
