Materials and Methods: The outcomes of 12 patients with USPR (group A) and 18 patients with open repair (group B) from January 2015 to February 2017 were analyzed retrospectively. The postoperative clinical evaluations were performed using the Arner-Lindholm scale, American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Achilles tendon total rupture score (ATRS), and visual analogue scale for the overall satisfaction and cosmetic satisfaction with the scar, and the starting time of single heel raises. The complications were also evaluated. Results: The Arner-Lindholm scale, AOFAS ankle-hindfoot score, ATRS, starting time of single heel raises were similar in both groups (all p>0.05). Group A showed a significantly higher overall patient s satisfaction and cosmetic satisfaction in than group B (all p<0.05). Two cases of Achilles tendon elongation were encountered in group A, and 1 case of re-rupture with deep infection and 1 case of superficial infection were experienced in group B. Conclusion: USPR showed good clinical outcomes and high satisfaction as well as a low rate of complications, such as sural nerve injury. Therefore, USPR can be considered as an effective surgical treatment option for Achilles tendon ruptures.

523 Comparative Study with Two Repair Methods of Ruptured Achilles Tendon 대상및방법 1. 연구대상본연구는충남대학교병원의 Institutional Review Board (IRB) 승인을얻어진행되었다 (IRB No.: CNUH 2017-09-016). 2015년 1 월부터 2017 년 2월까지본원에서이학적검사및자기공명영상 (magnetic resonance imaging, MRI) 검사상아킬레스건파열로진단받아초음파유도하경피적아킬레스건봉합술을시행받은 12 예 (A군) 와개방적봉합술을시행받은 18예 (B군) 를대상으로하였다. 2016년 2월까지개방적봉합술을시행해왔으며, 그이후에파열간격이 40 mm 이하인경우개방적술식과보존적치료의절충적치료로경피적봉합술을시행하였다. 성별은 A군남자 11 예 (91.7%), 여자 1예 (8.3%) 였으며, B군남자 16예 (88.9%), 여자 2예 (11.1%) 였다. 수상당시나이는 A군 39.4세 (28-55세), B군 40.2세 (28-52세) 였다. 수상기전은대부분스포츠손상으로 A군 11예, B 군 16예였으며, 나머지 3예는실족에의해파열되었다. MRI상종골부착부로부터아킬레스건파열위치는 A군 58.0 mm (40.5-85.0 mm), B군 57.6 mm (42.5-86.0 mm) 였고, 파열간격은 A군 21.8 mm (7.5-40.0 mm), B군 23.8 mm (10.2-43.2 mm) 였다. 수술은수상일로부터 A군에서는 3.5일 (0.5-6.5일), B군에서는 3.0일 (0.5-6.0 일 ) 에시행하였다 (Table 1). 급성파열의경우만을대상으로하였으며, 3주이상의만성파열, 개방성파열, 종골부착부파열, 타병원에서수술후재파열, 만성아킬레스건병증, 신경근육질환또는말초혈관질환진단을받은경우, 전신스테로이드나면역억제제치료를받은경우, 그리고최종추시기간이 6개월미만인경우는제외하였다. 두군모두단일술자에의해시행되었으며, 평균추시기간은 A군에서 11.2개월 (6-17개월), B군에서 16.0개월 (8-24개월) 이었다. 수술및하지마취는한정형외과의사에의해시행되었으며, 모든마취는초음파유도하국소신경차단술 ( 대퇴신경, 좌골신경, 후방대퇴피신경차단 ) 로시행하였다. 마취전에환자를복와 위로위치시킨후슬관절을 90 굴곡한중립위에서건측의발목각도를측정하여수술시참고로하였고, 파열부위와비복신경의주행경로를미리표시하였다. 2. 초음파유도하경피적봉합술지혈대를착용시키지않고복와위에서진행하였고, 수술장에서도초음파 (MyLab25Gold; Esaote, Genoa, Italy) 를준비하여탐촉자를소독된비닐로감쌌다. 봉합사는 1-0 Vicryl (Ethicon Inc., Somerville, NJ, USA) 을사용하였고, modified Kessler 술식을사용하여 2 strand로 2회봉합하였다 (Fig. 1). 초음파로바늘이건의실질까지두껍게통과하는지, 비복신경을손상시키지않는지실시간으로확인하면서수술을진행하였다 (Fig. 2). 건의종골부착부에서봉합사를먼저통과시켜단열원위부건단으로부터근위부건단으로통과시켰다. 근위부에서 2-3번더종축으로통과시킨후반대편으로이동하여다시근위부에서원위부종축으로통과시켰다. 종골부착부에서횡축으로통과시켜첫바늘구멍으로봉합사를빼낸후수술전건측의슬관절굴곡시발목의중립각도보다약 10 더단축하여족저굴곡된상태에서최종봉합을하였다 (Fig. 3). 같은바늘구멍을통해이과정을 1회더반복하여총 4 strand가되도록하였다. 바늘이나온구멍으로실을빼내어다시바늘을넣었기때문에바늘이봉합사를관통하여중간에끊어지지않도록주의하였고 (Fig. 4), 이를방지하기위해나머지실을바늘의진행방향과반대로당긴상태에서바늘을같은구멍으로넣어피부의아랫면을살짝긁으며들어가서봉합을진행하였다.

This figure shows that the needle penetrates the suture material (Vicryl). Special attention is needed to prevent this. 성별, 나이, 수상기전, 파열위치, 파열간격, 수상일로부터수술일까지의시간모두두군간유의한차이는없었다 ( 모두 p>0.05). 피부절개길이는 A군에서는바늘구멍흔적만있었고, B군에서는평균 5.7 cm (5.2-6.3 cm) 였다 (Fig. 5). 수술후 Arner-Lindholm scale은 A군에서우수 4예 (33.3%), 양호 8예 (66.7%) 였으며, B군에서우수 6예 (33.3%), 양호 11예 (61.1%), 불량 1예 (5.6%) 로두군간유의한차이는없었다 (p=0.884). AOFAS 점수는 A군 92.3점 (85-100점 ), B군 91.6점 (61-100점) 으로유의한차이가없었고 (p=0.755), ATRS 또한 A군 88.9점 (77-97점), B군 87.6점 (57-97점) 으로유의한차이가없었다 (p=0.983). 재파열과심부감염으로재수술을받았던 B군의 1예를제외하고양군모두한쪽발꿈치들기가가능하였고, 그시기는수술후 A군 3.75개월 (3-6개월), B군 3.65개월 (3-6개월) 로유의한차이가없었다 (p=0.645). 반면, 수술후결과에대한전반적인만족도는 A군 9.1 (7-10), B군 8.2 (2-10) 로유의

B군에서는 1예의심부감염및재파열과 1예의천부감염이나타났다. 심부감염및재파열이발생한환자는변연절제술, 세척술로감염을조절한후회전피판술을시행하였으며이후비복건막 turn-down 피판술을시행하였다. 천부감염이발생한환자는변연절제술및세척술만으로별다른소견없이회복되었다. 고찰 스포츠활동의증가로아킬레스건파열의유병률은높아지고있으나아직일치된이상적인치료법은나와있지않다. 14) 기존의개방적봉합술에대한감염, 유착및창상관련합병증이보고되어왔고 1,2) 보존적치료에대한연구들이많이진행되면서비수술적인치료가점점대두되고있지만, 1,3) 여전히건강하고활동적인환자에서는수술적치료가선호된다. 개방적봉합술과보존적치료의중간단계의치료방법으로서 1977년 Ma와 Griffith 15) 가경피적봉합술을보고한이후많은개방적봉합술과의비교연구가진행되어왔고, 이를개선한여러 MIS에대한연구도진행중이다. 일부저자들은경피적봉합술이피부합병증을줄이면서개방적봉합술과유사하게우수한임상적, 기능적결과를보였다고하였고, 5,14,16) Hsu 등 17) 은합병증에있어서 percutaneous Achilles repair system (PARS) 과개방적봉합술간차이가없다고하였으며, Yang 등 2) 은수술시간, 감염, AOFAS 점수에서개방적봉합술보다낫다고하였다. 반면, 비복신경은다양한해부학적경로를가지므로경피적봉합술은항상비복신경의손상가능성에노출되어있고, 18) 여러연구에서경피적봉합 Table 2.

527 Comparative Study with Two Repair Methods of Ruptured Achilles Tendon 술시행시약 15% 의확률로비복신경이손상되었음을보고하였다. 8,19) 그리고 Soubeyrand 등 20) 에의하면경피적봉합술에서봉합사의바늘을 blind하게삽입할경우약 55% 에서아킬레스건실질내에정확하게위치하지못했다고하였고이는봉합강도를약화시키는요인으로작용할수있다. 이러한경피적봉합술들의단점들을보완하기위해저자들은초음파유도하경피적봉합술을시행하게되었고, 비복신경의위치를실시간으로확인하면서손상을 100% 피할수있었다. 그리고바늘이건의실질내로들어가는것을확인하면서진행하였기에봉합사가피하로통과하거나건의표층만통과할가능성을최소화했으며, 더강한봉합을이루도록하였다. 본연구는첫째, 기존의초음파유도하경피적봉합술 20-23) 과달리저자들의방식으로초음파유도하경피적봉합술 (A군) 을시행하여개방적봉합술 (B군) 과비교한연구라는점에서의의가있다. 둘째, 본연구에서는 2회의 2 strand의 modified Kessler 봉합술만으로재파열없이좋은임상적결과를보여특별한기구 (PARS, Achilles midsubstance speedbridge, Achillon, etc.) 및자체적개발기구 5) 나고난도의봉합술기없이도쉽고간편하게시행할수있는방법이다. McCoy와 Haddad 24) 는카데바연구에서 4 strand로아킬레스건을봉합했을때, Krackow, Bunnell, 그리고 Kessler 봉합술간의강도에유의한차이가없다고하였다. 셋째, 아킬레스건을노출시키지않아건의혈액순환을방해하지않고, 흡수성봉합사를사용하여봉합사의자극반응을낮춤으로써보다생체적합한 (biocompatible) 봉합이되도록하였다. 비흡수성봉합사는충분한기간동안인장강도가유지되지만만성적인피부자극을줄수있는반면, 9,25) 흡수성봉합사는충분한기간의인장강도유지가어렵지만, 매듭유지가잘되고자극이덜하며파열된인대의회복에도움을줄수있다는장점이있다. 9,26) 흡수성봉합사인 Vicryl (polygalactin) 은인장강도가 2주후 75%, 3주후 50%, 4주후 25% 로감소하고보통 56-70일이지나면완전히흡수되는특성이있으나, 9,25,27) 염증기 (inflammatory phase, 0-72시간 ), 증식기 (proliferation phase, 2일-6주 ) 를거쳐재형성기 (remodeling phase, 4주-12개월 ) 에이르는건자체의자연치유과정이진행되므로초기고정및단계적재활이뒷받침된다면초기의충분한봉합강도를제공하리라생각됐다. 실제로 Kocaoglu 등 28) 과 Baig 등 29) 이흡수성봉합사를이용한아킬레스건봉합술에대해보고한바에따르면, 비흡수성봉합사보다더적은자극반응, 감염등의합병증이나타났고우수한임상적결과를보였다. 저자들의이전연구 9) 및본연구에서도심부감염으로재파열된 1예를제외하고, 4주간의비체중부하단하지석고고정을비롯한수술후치료프로그램을통하여재파열없이치료할수있었다. 본연구의제한점은후향적연구로환자수가적어서표본크기및두군별정규성을만족하지못하였다는점이다. 그리고건의재형성기가 4주에서 12개월까지진행된다는점을고려할때, 최 종추시기간이짧다. 또한두군간다른봉합술을이용하였기에봉합방법이예후에영향을미칠수있는부분을고려하지않았다. 그리고두방법의수술을시행함에있어확실한적응증을설정하지않았다는점에서도제한점을가진다. 보다많은환자들을대상으로보다긴추시기간의전향적연구가필요하리라생각된다. 그리고 Clanton 등 30) 의카데바연구에따르면, MIS와개방적봉합술의최종강도는유사하나초기봉합부위신연에있어 MIS 에서더취약하다고하였고, 본연구에서도이를고려하여건측보다 10 더족저굴곡상태로단축시켜봉합하였으나 2예의수술후실족으로인한초기봉합부위신연이있었던바, 경피적봉합술및 MIS 후초기고정기간에대한추가적인연구및환자에대한교육이필요하리라생각된다. 결론 초음파유도하경피적봉합술 (A군) 은개방적봉합술 (B군) 과비교할때비슷한임상적결과를제공할뿐아니라더높은주관적, 미용적만족도와함께기존경피적봉합술의합병증인비복신경손상등을최소화할수있는결과를보였다. 아킬레스건파열의치료에있어최적의치료법에대한결론이나와있지않은바, 초음파유도하경피적봉합술은유용하게고려될수있을것으로생각된다.

Arner-Lindholm scale, American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Achilles tendon total rupture score (ATRS), 수술후만족도 ( 전반적 / 미용적 ) 에대한 visual analogue scale (VAS), 한쪽발꿈치들기가능시기로임상적평가를하였고, 그외합병증에대해평가하였다. 결과 : 각군별평균 Arner-Lindholm scale, AOFAS ankle-hindfoot score (A군: 92.3점 /B군: 91.6점 ), ATRS (A군: 88.9점 /B군: 87.6점 ), 한쪽발꿈치들기가능시기 (A군: 3.75개월 /B군: 3.65개월 ) 는통계적으로유의한차이가없었으나 (p=0.884, p=0.755, p=0.983, p=0.645) 수술후결과에대한전반적, 미용적만족도는 B군 (8.2/6.7) 에비해 A군 (9.1/9.9) 에서유의하게높았다 (p=0.035, p=0.001). A군에서 2예의봉합부위신연 (elongation) 을보였고, B군에서 1예의심부감염으로인한재파열과 1예의천부감염을보였다. 결론 : 초음파유도하경피적봉합술은개방적봉합술과비교할때비슷한임상적결과를제공할뿐아니라더높은주관적, 미용적만족도와함께비복신경손상등의합병증을최소화할수있는결과를보여아킬레스건파열의치료에있어유용하게고려될수있을것으로생각된다. 색인단어 : 아킬레스건, 초음파, 경피적봉합술, 비복신경, 흡수성봉합사 접수일 2017 년 10 월 9 일수정일 2017 년 11 월 2 일게재확정일 2017 년 12 월 6 일책임저자강찬 35015, 대전시중구문화로 266, 충남대학교의과대학정형외과학교실 TEL 042-338-2480, FAX 042-338-2482, E-mail faschan@hanmail.net, ORCID https://orcid.org/0000-0002-6651-0340 대한정형외과학회지 : 제 53 권제 6 호 2018 Copyright 2018 by The Korean Orthopaedic Association This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons.org/licenses/by-nc/4.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
