Conservative Treatment of Tendon Injuries.

Tendon injuries or tendinopathy is a common painful and disabling conditions resulting from overuse and aging. Tendinopathy remains a challenging clinical problem because response to different treatment modalities is usually unsatisfactory and recovery is slow. We performed an extensive literature review focusing on nonsurgical treatment options for tendinopathies, including nonsteroidal anti-inflammatory drugs, corticosteroid, eccentric exercise, extracorporeal shock wave therapy, therapeutic ultrasound, hyaluronic acid, platelet-rich plasma, prolotherapy, polydeoxyribonucleotide, and stem cells, aimed at providing the most updated evidence as a guideline for caregivers.
