Our Summary

Tendon injuries are often seen in medical practice and traditional treatments usually can’t fully restore the tendon’s original structure and function. There are still many challenges in speeding up healing, making the newly regenerated tendon stronger and preventing scar tissue formation. Tendon tissue engineering is a new technique that holds promise for repairing tendons. It involves using a combination of material science, cell biology, and molecular biology to create working structures. The key research question is how to maximize the healing potential of these elements. Future research will focus on finding the best combinations of cells, biological signals, and support structures to create tissue that acts like a healthy, natural tendon. This article reviews various aspects of the topic, including creating support structures, choosing the right cells, and strategies for controlling healing-related biological signals. The goal is to increase understanding of tissue engineering techniques in tendon repair and to inspire new applications in this field.

Doctor’s Tip

A doctor might tell a patient that following a proper rehabilitation program after tendon repair surgery is crucial for a successful recovery. This program may include exercises to gradually strengthen the tendon, as well as techniques to improve flexibility and range of motion. It is important for the patient to follow the recommendations of their healthcare provider and physical therapist to ensure the best possible outcome. Additionally, the patient should avoid activities that may put excessive strain on the repaired tendon to prevent re-injury.

Suitable For

Patients who may be recommended tendon repair include those who have suffered from tendon injuries due to trauma, overuse, or degenerative conditions such as tendonitis or tendon tears. These injuries can affect tendons in various parts of the body, including the shoulder, elbow, wrist, knee, and ankle. Individuals who have failed to respond to conservative treatments such as rest, physical therapy, or corticosteroid injections may be candidates for tendon repair surgery. Additionally, athletes or individuals who require full use of their tendons for daily activities or work may also benefit from tendon repair to restore function and prevent further damage.

Timeline

  • Before tendon repair:
  1. The patient sustains a tendon injury, which may result from trauma, overuse, or degenerative conditions.
  2. The patient experiences symptoms such as pain, swelling, limited range of motion, and difficulty performing daily activities.
  3. The patient seeks medical treatment, which may include rest, physical therapy, medication, and/or immobilization.
  4. If traditional treatments are not effective, the patient may be recommended for tendon repair surgery.
  • After tendon repair:
  1. The patient undergoes tendon repair surgery, which may involve suturing the torn tendon, using a graft to replace the damaged tendon, or other techniques.
  2. The patient goes through a period of post-operative care, which may include pain management, wound care, physical therapy, and activity modification.
  3. The patient gradually resumes normal activities as the tendon heals, following the guidance of their healthcare provider.
  4. Over time, the patient may experience improved strength, range of motion, and function in the repaired tendon.
  5. The patient continues to follow up with their healthcare provider for monitoring and further rehabilitation as needed.

What to Ask Your Doctor
