When tendinitis has been present for several months or more, it progresses to become chronic tendinitis or tendinosis. Tendinosis includes degenerative changes in the collagenous matrix of a tendon that weakens and increases its likelihood of sustaining a tendon rupture. Regenerative medicine treatments using image-guided PRP injections aim to resolve this painful condition by promoting natural healing and decreasing the likelihood of a catastrophic tendon rupture.

Tendinitis and Tendinosis Overview

Tendinitis refers to inflammation of a tendon, usually of less than several months duration. Symptoms of tendinitis can vary from a burning sensation around the inflamed tendon, to aching pains and local joint stiffness. Sometimes swelling along the tendon occurs with associated warmth and redness. If tendinitis symptoms become chronic and persist for several months or more, then the tendinitis condition progresses to chronic tendinitis, also called tendinosis.

Chronic tendinitis (tendinosis) of the Achilles tendon, rotator cuff of the shoulder, lateral epicondyle of the elbow (Tennis Elbow), medial epicondyle of the elbow (Golfer’s Elbow), hip area, and patellar tendon of the knee are common causes of pain in adults. Both stem cell and PRP therapies promote natural healingof an injured, partially torn, or degenerative tendon. Stem cell and/or PRP treatments are indicated for promoting natural healing of chronic tendinitis (tendinosis). The choice of which cellular therapies to use depends on the extent of tendon injury and surrounding tissue injury contributing to the patient’s symptoms. Often times, PRP treatments are performed as the initial treatment for significant inflammation of a non-torn tendon. For severe tendinosis or partial tendon tears, more significant regenerative medicine treatments such as stem cells + PRP may be chosen.

Platelet-rich plasma (PRP) therapy is a recommended cellular therapies to promote natural healing, and to prevent progression of tendon degeneration that could lead to tendon rupture. In the case of a severe tendon rupture, a surgical tendon repair may be considered to reattach and realign the torn tendons. In the case of a partial tendon tear or rupture, a stem cell treatment with PRP may be considered to promote repair and regeneration at the injury site.

Regenerative medicine specialists at MRM advise their patients with chronic tendinitis (tendinosis) to avoid corticosteroid injections into or near the involved tendons for at least three months prior to having a stem cell and/or PRP treatment. This is done to optimize treatment success. Local wound healing is significantly impaired in the presence of injected corticosteroids. Similarly, over-the-counter medications such as non-steroidal anti-inflammatory drugs (NSAIDs) and aspirin should be avoided for at least 10 days prior to any stem cell or PRP treatment, and for several weeks afterwards. Both NSAIDs and aspirin impair platelet function, as well as suppress elements of local wound healing.
