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.

견봉하윤활낭절제술을제외한나머지수술과정은동일하게진행되었다. 전층파열의크기분류는 Cofield 분류 10) 를이용하였다. 모든환자는술후 6주간외전보조기를착용하였으며술후다음날부터술후 2주사이에수술부위의상태에따라서시계추운동및수동적견관절운동을시작하였다. 술후 6주부터보조적인능동적관절운동 (active-assisted exercise) 을시행하였다.

모든환자의의무기록 ( 입원및외래의무기록, 수술기록, 초음파사진및영상 ) 은후향적으로분석되었으며, 파워도플러를이용한 Modified Newman 분류에따른신생혈관형성에대한관찰자내및관찰자간신뢰도를확인하기위하여임상결과를숨긴채초음파동영상을이용하여 2명의정형외과전문의에의해독립 적으로측정되었다.

VAS는수술전, 술후 6, 12, 24, 48, 72시간, 2, 6주, 3개월의평균이각각 2.3, 2.0, 6.3, 3.5, 2.6, 2.2, 0.8, 0.5, 0.2였으며양군간에통계적으로유의한차이는확인할수없었다 (Table 3). 수술전통증과비교해보면양군모두에서술후 48시간 (Group A: 0.2±1.8, p=0.465; Group B: 0.4±1.9, p=0.233), 72시간 (Group A: -0.1±1.9, Table 2.

Modified Newman 분류에따른혈관신생에대하여관찰자내및관찰자간신뢰할수있는수준의신뢰도를확인할수있었다 (Table 5). 수술후 3개월까지건의단락이소실된재파열소견을보인예는없었다. 고찰 견봉하윤활낭에는고유수용성감각및통각에관여하는신경말단및건의재생에관여하는다양한세포들이포함되어있는것으로알려져있으나회전근개전층파열시통증을유발하는염증성사이토카인을분비하는중요한역할을하는등상반된조직학적의의를갖는것으로알려져있다. 2,4,12-14) 그러나회전근개봉합술시염증의원인이되는윤활낭에의한통증및봉합된건의장력해소를위해서완전한윤활낭절제술은필수적인과정으로 Table 3.

Boss 등 15) 은회전근개봉합술후 48시간이내에수술후심한통증이발생함을보고하였다. 이러한수술후초기통증조절을위해견봉하일회성 bupivacaine 국소주사와다중통증조절법의안정성과유용성이보고된바있다. 11) 본연구에서도동일한방법을적용하여양군모두에서수술후초기통증을효과적으로조절할수있었으며술후 2주이후에는술전에비해의미있는통증호전을얻을수있음을확인할수있었다. 파워도플러는움직이는혈구의속도대신신호의크기만을보여주므로영상의노이즈가작아서일정한혈류의흐름보다는혈액이정체된곳의미세한혈류를관찰하는데유용한방법으로알려져있으며, 이러한특성으로인하여조직의관류 (perfusion), 염증, 신생혈관의확인에이용되고있다. 16) Kitchen과 Kane 17) 은건강한사람들을대상으로시행한정상관절에대한초음파검사상견관절에서는 60예전체예에서 0단계의파워도플러검사결과를보고하였다. 본연구에서는수술전시행한파워도플러검사상평균 0.8의변화를양군모두에서확인할수있어서통증의원인이되는견봉하윤활낭염을파워도플러검사를통하여반정량적으로확인할수있었다. Fealy 등 18) 은회전근개봉합술후견봉하윤활낭주위의혈류형성이가장활발하게진행되며이러한혈관신생반응은수술후가장강하게형성되고, 시간이경과함에따라줄어드는양상을보임을보고하였다. 그러나 Urita 등 19) 은경골-유사봉합술을시행한환자의윤활낭주위혈류신생이 3개월까지증가한이후 감소하는양상을보임을보고하였다. 본연구에서도양군모두에서수술전과비교하여술후 6주와 3개월째의미있는신생혈관증가를확인할수있었으나술후 6주에비해 3개월째증가된신생혈관의변화에대한통계적차이를확인할수는없었다. 본연구는다음과같은한계를가진다. 첫째, 전향적연구보다비뚤림가능성이큰후향적연구라는점이다. 둘째, 최소윤활낭절제술을시행하던중환자의건유착정도및윤활낭상태에따라서윤활낭전절제술로전환한환자들이포함되어있어서선택의비뚤림을배제할수없다는점이다. 셋째, 혈류를반정량적으로평가하기위하여 Newman 의분류를변형하여적용하였으나류마티스활액막염에대한평가기준을정상적인치유과정의염증반응에적용하였다는점이다. 넷째, 본연구는혈류증가소견이치유와관련되는지에대해서확인하고자하는것이아니라초기통증과의관련여부를확인하는데있는바, 수술이후통증영향이큰첫 3개월로추시기간을설정하여짧은추시기간으로인하여초기통증및신생혈관형성에대한비교는가능하였으나신생혈관형성의정도에따른재파열및임상평가를비교할수없었다는점이다. 다섯째, 제거되는윤활낭의양을정량화하기위하여소파열-대파열이하로환자들을제한하였으나명확하게수치로정량화할수없었다는점이다. 그러나동일기관에서동일술자에의해윤활낭절제술을제외한동일한방법으로수술및추시관찰이진행되어결과도출과정에서발생할수있는비뚤림을최소화할수있었다고생각하며이점이본연구의강점으로생각된다. 요약하자면윤활낭절제술의양에따른수술시간, 통증경감, 신생혈관형성에차이는없었으나양군모두에서술후 48시간에술전통증상태와유사한정도로통증이호전되었으며 2주에의미있는통증호전을확인할수있었다. 파워도플러초음파를이용하여술후 6주와 3개월에신생혈관증가소견을확인할수있었으나회전근개치유에대한연관성을확인하기위해서는장기간추적관찰이필요할것으로판단된다. 결론 파워도플러초음파를통하여수술전과비교하여술후에양군모두에서의미있는신생혈관증가소견을확인할수있었으나
