OBJECTIVE: To evaluate noninvasive monopolar capacitive-coupled radiofrequency
(mcRF) for the treatment of pain associated with lateral elbow tendinopathies.
DESIGN: Prospective, single-center, single-arm, 1-year follow-up. SETTING:
Private sports medicine practice. PARTICIPANTS: Thirty-nine consecutive patients
with diagnosis of lateral elbow tendinopathy (including 3 bilateral cases, for a
total of 42 elbows) participated in the study. All patients had been
unsuccessfully treated with a variety of nonoperative therapies (eg, nonsteroidal
anti-inflammatory drugs, corticosteroid injections, and braces) for at least 3
months before they were enrolled in the study. INTERVENTION: Patients were
treated with mcRF technology in the office without local anesthetic or any
particular preparation. Anatomic landmarks and careful determination of the most
tender point defined the area treated; rapid and precise mcRF pulses were
delivered covering the area in a staggered fashion; and 10 additional pulses were
delivered directly to the point of maximum tenderness (total of 100 pulses).
Patients returned to activities of daily living without restriction and were
instructed to avoid nonsteroidal anti-inflammatory drugs and/or ice over the
treated area. Physical therapy or other treatment modalities were disallowed.
RESULTS: The presence of pain before enrollment ranged from 15 weeks to 2 years
(average, 32 weeks). Visual analog scores at rest, with regular activity, and
with triggering events were gathered at 3, 6, and 12 months. The Nirschl Tennis
Elbow Questionnaire and patient satisfaction also were used to evaluate study
outcomes. Follow-up average was 423 days (range, 330-487 days). On the basis of
the study's multifactorial success criteria, 81% of participants had successful
outcomes. Furthermore, 89% of the patients who completed the study were
completely or moderately satisfied with the outcome. CONCLUSIONS: Outcomes of
this study suggest that noninvasive mcRF may have a role in the treatment of pain
associated with lateral elbow tendinopathies.
The noninvasive nature of the
procedure and the safety and efficacy suggested by this study may offer
significant advantages over current treatment alternatives. Further research in
the form of a randomized clinical trial is recommended.
