This podcast explores the use of lasers for tendon repair and regeneration. It discusses the healing process of tendons, common sites for injuries, and managing pain. It also explains the functions and mechanisms of low-level laser therapy and its benefits in promoting blood vessel creation and reducing scar tissue buildup.
Laser therapy promotes angiogenesis and collagen synthesis, aiding in the efficient repair of damaged tendons.
Interrupting or impeding the three phases of tendon repair can lead to prolonged pain and dysfunction, emphasizing the importance of timely intervention and complete healing.

Tendon injuries and their causes
Tendon injuries can occur due to traumatic events or repetitive motion over time. They commonly affect athletes, the elderly, and anyone engaged in activities that put strain on tendons. Tendon tears can happen in various areas of the body, with Achilles tendon and rotator cuff injuries being the most common. These injuries can result in partial tears or complete tears, with the former being more prevalent. Tendon injuries are often characterized by pain and can lead to disability if not properly addressed.
The three phases of tendon repair
Upon sustaining a tendon injury, the repair process involves three distinct phases: the inflammatory phase, the proliferative phase, and the remodeling phase. The inflammatory phase occurs within the first 48 hours after the injury, during which blood clots form and fibrin attaches to the damaged tissue. The proliferative phase involves the formation of granulation tissue and the synthesis of collagen. Lastly, the remodeling phase focuses on cleaning out old damaged cells, reducing scar tissue, and rebuilding collagen to restore the tendon's strength and flexibility. These phases are crucial for complete healing, and interrupting or impeding any of them can lead to prolonged pain and dysfunction.
The role of laser therapy in tendon repair
Laser therapy, also known as photo biomodulation or light therapy, has proven effective in promoting tendon healing and reducing pain. The therapy stimulates angiogenesis, the creation of new blood vessels, during the inflammatory phase, aiding in the transport of nutrients and aiding repair. Laser therapy also promotes collagen synthesis by encouraging fibroblast proliferation, resulting in the growth of healthy muscle fibers. By reducing pro-inflammatory cytokines and promoting the expression of anti-inflammatory cytokines, laser therapy minimizes scar tissue and the likelihood of tendon fibrosis. Laser therapy helps the body go through the repair process efficiently, leading to better tendon healing and fewer complications down the road. Early intervention with laser therapy is particularly beneficial, but even long-standing tendon injuries can still significantly benefit from laser treatment.
