Tendon Fenestration Versus Surgery for the Treatment of Chronic Lateral Epicondylosis

"This treatment will be administered by an orthopedic surgeon specialized in upper limb surgery.~1. Skin disinfection; Local anesthesia (lidocaine 1%).~2. Skin incision, slightly anterior to lateral epicondyle.~3. Exposure of the plane between the tendon and fascia.~4. Extensor Carpi Radialis Longus (ECRL) tendon is lifted to expose the Extensor Carpi Radialis Brevis (ECRB) tendon.~5. Excision of diseased tissue of the ECRB tendon.~6. ECRL tendon is sutured back to the fascia. The skin is closed.~7. Patient is monitored for 30 minutes after procedure."

"This treatment will be administered by a fellowship-trained MSK radiologist.~1. Patient's elbow at 70 degrees of flexion with the forearm pronated resting on an examination table.~2. Skin disinfection. Local anesthesia, skin, superficial fascia and tendon, with lidocaine 1%.~3. Using a 22 G needle under continuous ultrasound guidance, several passes (about 20-30) within the abnormal area of the tendon, contacting the bone, until the area softens.~4. Patient monitored for 30 minutes, before being discharged."
