Can Shockwave Therapy Improve Tendon Metabolism?

Area of Science:

• Orthopedics
• Regenerative Medicine
• Biomedical Engineering

Background:

• Shockwave therapy is increasingly used for tendon injuries, with growing evidence of clinical effectiveness.
• Fundamental in vivo studies on the biological mechanisms of shockwave therapy are limited.
• Key proposed mechanisms include calcification destruction, pain relief, and mechanotransduction-driven tissue regeneration.

Purpose of the Study:

• To review the current understanding of shockwave therapy's biological actions in tendinopathy.
• To identify gaps in fundamental research regarding shockwave therapy's effects.
• To explore the challenges in establishing optimal treatment protocols and recommendations.

Main Methods:

• Literature review of in vivo and clinical studies on shockwave therapy for tendinopathy.
• Analysis of proposed working mechanisms of shockwave therapy.
• Identification of research gaps and areas for future investigation.

Main Results:

• Shockwave therapy demonstrates potential for tendon injury management through pain reduction and tissue regeneration.
• Heterogeneity in devices (focused vs. radial), protocols, and patient responses complicates treatment standardization.
• Limited data exists on shockwave therapy's efficacy in patients with metabolic tendon disorders.

Conclusions:

• Further fundamental and clinical research is essential to elucidate the precise biological effects of shockwave therapy.
• Optimizing shockwave therapy approaches requires addressing heterogeneity in systems, protocols, and patient populations.
• The role of shockwave therapy in metabolic tendon disorders remains largely unexplored and warrants investigation.
