Brief summary
The purpose of this study is to determine whether radio-frequency (RF)-based plasma micro-tenotomy has a positive effective for the treatment of shoulder impingement syndrome with cuff tendinosis. Eighty patients with impingement syndrome and cuff tendinosis that treated arthroscopic were enrolled in the study. Patients were randomly assigned to receive either arthroscopic subacromial decompression alone (ASD group, n=40) or arthroscopic subacromial decompression combined with RF-based plasma micro-tenotomy (RF group, n=40). Clinical outcome data including VAS(Visual Analogue Scale) pain score, Shoulder range of motion (ROM), ASES(American Shoulder And Elbow Surgeons) score, UCLA(University of California, Los Angeles) score, Constant-Murley score and SST(Simple Shoulder Test) score were recorded preoperatively and at postoperative 3-week, 6-week, 3-month, 6-month and 1-year.
Interventions
PROCEDURERF micro-tenotomy
an additional bipolar RF-based device (TOPAZ, Arthrocare, Austin, TX) connected to a System2000 generator (Arthrocare, Austin, TX) was used to perform the micro-tenotomy. The device functions using a controlled plasma-mediated RF-based process (Co-ablation).The device was placed on the tendon perpendicular to its surface, for 500 milliseconds, and micro-debridement was performed at 5-mm intervals by a 2-row fashion, which covered most of the foot-print region of the supraspinatous tendon and at a depth of 3 to 5 mm
