Monopolar radiofrequency energy for arthroscopic treatment of shoulder instability in the athlete

Monopolar radiofrequency energy is increasingly being used in the treatment of shoulder instability. Basic science studies and early clinical results have shown that application of thermal energy can result in successful shrinkage of the shoulder capsule. This procedure is useful in treating certain traumatic and recurrent instability conditions of the shoulder especially in the athlete where range of motion is preserved, recovery is faster than with open procedures, and there, is little disruption or alteration of inherent anatomy. The procedure is technically easy to perform, and the complication rate is low. Success, however, depends on proper patient selection, attention to the rehabilitation program, and patient compliance. Long-term follow-up will be necessary to determine if results for this procedure will deteriorate over time, especially in patients with multidirectional instability.
