ROCHESTER, Minn.--(BUSINESS WIRE)--Many athletes know the frustration of being sidelined by tendon disorders, like Achilles tendinitis and tennis elbow.

One technique, a tenotomy, uses repeated needlesticks to break up scar tissue in the tendon, prompting the body’s own cells to begin the rebuilding process.
