Radiofrequency (RF) is a heat treatment applied to the tendon during arthroscopic surgery. It requires a special RF-based device used to generate the energy waves. A needle-like wand is used to apply the energy to the tendon. The tip of the wand is touched to the surface of the tendon.

Many tiny holes are "burned" into the tendon. The new wound sets up an inflammatory response to begin the healing process. New blood flow to the area helps restore tissue to normal.

Surgeons may not be familiar with the use of this treatment method. They may not have the equipment or training. On the other hand some surgeons may be concerned about the amount of tissue damage that can occur with this treatment. Damage can occur to nearby tissues. Holes can be burned too deep, going into the cartilage or joint.

More studies are needed to show long-term results before RF tenotomy is adopted as a standard treatment for tendon problems.
