Whether it is 5k or a Marathon, from April to October running enthusiasts have no trouble finding a running event to participate in. Here in my town of Champaign, some 20,000 participate in one of the Illinois Marathon events. With these races comes training and where there is training, you can find injury close by.

Causes and Treatment of Achilles Tendinopathy

Overview and etiology:

Pain and injury to the Achilles tendon is often thought to be a result of inflammation.

Pain and injury to the Achilles tendon is often thought to be a result of inflammation.

The term “tendinitis” or any [insert any body part] with “itis” is tossed around as if it is the only possible cause for musculoskeletal pain. However, the “itis” is not really true. A tendon, specifically the Achilles tendon, is not really inflamed, rather it is deranged (tendiopathic / tendinopathy). In January 2013 the Annals of Human Genetics published an article that demonstrated Achilles Tendinopathy is associated with gene polymorphism (Abrahams, et al., 2013). COL51A is a gene that encodes the development and organization of Type V collagen. This collagen can be found in ligaments, tendons, and connective tissue. COL51A plays an integral role in development and maintenance of connective tissue. Abrahams, et al. (2013) demonstrated that polymorphisms occur in the COL51A gene causing altered structure of collagen resulting in tendinopathy.

The tendon may become fusiform or thickened, but it is due to cellular derangement rather than inflammation. Kannus and Jozsa in a controlled study of 891 patients with Achilles tendon rupture found that 97% of patients had degenerative changes in the ruptured tendon. The study also found that 34% of asymptomatic tendons also had degenerative changes (2) Continue reading
