Our Summary

This research paper discusses the potential benefits of hyaluronic acid in the treatment of tendon injuries, known as tendinopathies. Hyaluronic acid is a substance that has various properties depending on its molecular weight. Although the specifics of how this substance works within tendons are not fully understood, it has shown positive effects in both lab and preclinical studies. These include compatibility with biological tissues, stickiness (mucoadhesivity), ability to attract and hold water (hygroscopicity), and a balance of both liquid and solid properties (viscoelasticity). These properties may aid in the healing of tendons. The paper also mentions that clinical studies have shown promising results when using hyaluronic acid to treat different types of tendon injuries. Despite a lack of clear consensus in the medical community regarding the classification of hyaluronic acid based on its molecular weight, the researchers suggest that it could be beneficial in treating conditions like rotator cuff injuries, tennis elbow (epicondylitis), Achilles tendon injuries, and knee tendon injuries (patellar tendinopathy).

Doctor’s Tip

A helpful tip a doctor might tell a patient about tendon repair is to consider using hyaluronic acid as a treatment option. Hyaluronic acid has been shown to have physical-chemical properties that can contribute to tendon healing, and it has been used with promising results in various tendinopathies such as rotator cuff, epicondylitis, Achilles, and patellar tendinopathy. It is important to consult with your healthcare provider to see if hyaluronic acid could be a beneficial treatment option for your tendon injury.

Suitable For

Patients who are typically recommended tendon repair are those who have suffered from tendinopathies such as rotator cuff injuries, epicondylitis, Achilles tendon injuries, and patellar tendon injuries. These patients may experience symptoms such as pain, swelling, and limited range of motion in the affected tendon. Tendon repair may be recommended to improve function, reduce pain, and prevent further damage to the tendon. Patients with chronic tendinopathies that do not respond to conservative treatments such as physical therapy or medications may also be candidates for tendon repair surgery.

Timeline

Before tendon repair:

  • Patient experiences pain, swelling, and limited range of motion in the affected tendon
  • Patient may have tried conservative treatment options such as rest, physical therapy, and medication with limited success
  • Patient may have undergone imaging studies such as ultrasound or MRI to assess the extent of the tendon injury
  • Patient and healthcare provider discuss the option of tendon repair surgery as a treatment option

After tendon repair:

  • Patient undergoes tendon repair surgery, which may involve suturing the torn tendon back together or using a graft to replace the damaged tendon
  • Patient undergoes a period of rehabilitation and physical therapy to regain strength and range of motion in the repaired tendon
  • Patient may experience post-operative pain, swelling, and stiffness in the repaired tendon
  • Over time, patient gradually regains function and mobility in the repaired tendon as it heals and strengthens
  • Patient may require follow-up appointments with their healthcare provider to monitor the healing process and make any necessary adjustments to their rehabilitation plan
