Pain and Power Doppler Ultrasonographic Evaluation according to Bursal Preservation after Arthroscopic Rotator Cuff Repair: Comparison between Complete and Minimal Bursectomy in Early 3 Months / 대한정형외과학회잡지

ABSTRACT

PURPOSE: The purpose of this study was to compare the clinical and power Doppler ultrasonographic results of arthroscopic rotator cuff repair (ARCR) between using a complete and a minimal bursectomy. Moreover, we aimed to evaluate the pain-relief and neoangiogenesis according to bursal preservation. MATERIALS AND METHODS: Between December 2015 and August 2016, we performed a retrospective review of 78 consecutive patients who underwent ARCR due to full thickness rotator cuff tear (small-large sized tear). Thirty-six patients received ARCR using minimal bursectomy (Group A), while 42 patients received ARCR via complete bursectomy (Group B). The mean age was 57.8 years and the average symptom duration period was 20.3 months. Clinical result was assessed using a visual analogue scale (VAS) pain score due to evaluate the pain-relief and power Doppler ultrasonographic result was classified according to the modified Newman classification due to evaluate the neoangiogenesis. RESULTS: There was no statistically significant difference in operation time, pain-relief, and neoangiogenesis in accordance with bursal preservation between the two groups. Compared to the preoperative values, pain was significantly increased two weeks postoperatively in both groups (Group A −1.8±1.4, p=0.000; Group B −1.4±1.7, p=0.000). Compared to the preoperative values using the power Doppler ultrasound, neoangiogenesis was significantly improved at the postoperative 6 weeks (Group A 0.7±0.9, p=0.000; Group B 0.9±1.1, p=0.000) and 3 months (Group A 0.9±1.0, p=0.000; Group B 1.0±1.1, p=0.000) in both groups. CONCLUSION: Serial follow-up by power Doppler ultrasound before and after ARCR showed a neoangiogenesis of up to 3 months in both groups, but there was no difference in pain-relief and neoangiogenesis between the two groups.
