Objective : To evaluate the result of total hip arthroplasty(THA) with CLS expansion acetabular cup using press-fit technique. Methods and Materials : One hundred primary THA in 85 patient with a CLS expansion cup by press-fit technique were performed consecutively. Eighty-two hips were evaluated for clinical analysis by Harris hip score(HHS), and seventy-one hips were evaluated for radiographic analysis, including stability(cup migration and change of position), remodeling(change of polar gap and trabecular pattern), and early wear of polyethylene after a mean follow up of 4 years and 5 months. Result : Mean HHS was improved from 50.1 points preoperatively to 91.5 points at the most recent follow up. Initial adequate contact fit was found in 64 hips(90%). Radiolographically, optimal stabilities of acetabular cup at the most recent follow up were found in all hips. Polar gap in 31(88%) of 35 hips at postoperative radiographs disappeared at the most recent follow up. Periacetabular trabecular patterns were maintained or improved in all cases. Conclusion : CLS expansion acetabular cup fixation by press-fit technique guaranteed excellent implant stability and acetabular remodelling.

Purpose: To evaluate the effect of autotransfusion system in minimally invasive total knee arthroplasty (TKA). Materials and Methods: Seventy-one patients who underwent unilateral minimally invasive TKA between October 2009 and June 2010 were selected. The first group included 36 patients who received standard vacuum drainage and the second group, 35 patients who underwent autologous retransfusion drainage. In the first group, allogeneic blood transfusion was performed if the postoperative hemoglobin level was <7.0 g/dL or 7.0−8.0 g/dL with the presence of a medical complication and an anemic symptom. The second group received autotransfusion and allogeneic transfusion additionally according to the same criteria. Changes in the pre- and postoperative hemoglobin level, amount of auto- or allotransfusion, and frequency of allogeneic transfusion were assessed. Results: Allogeneic transfusion was required in 13 patients (36.1%) in the first group and four patients (11.4%) in the second group. The mean allogeneic transfusion volume was significantly low in the second group compared to the first group (64.4 mL vs. 278.9 mL; p<0.05). The hemoglobin level on the 1st postoperative day compared to the preoperative level decreased by 22.6% in the first group and 11.7% in the second group. The postoperative hemoglobin level was higher in the second group (p<0.05). Conclusions: Minimally invasive unilateral TKA with an autotransfusion system can be beneficial in patients with no medical complications because of the decreased allogeneic transfusion.

Purpose: The purpose of this study is to retrospectively analyze the clinical results of screws and Kirschner wire (K-wire) fixation in patients with fracture dislocation of Lisfranc joint and the consequence of screw breakage. Materials and Methods: Sixty patients underwent Lisfranc joint open reduction and removal of internal fixators from January 2007 to December 2011. Forty-nine cases (81.7%) underwent operations with screw alone, and 11 cases (18.3%) underwent operations with both screws and K-wires. Type of internal fixators, duration of internal fixator removal, breakage of internal fixators and satisfaction with reduction were investigated. Additionally, American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scales were analyzed. Results: The internal fixator was broken in 5 cases (8.3%). The average duration of instrument removal was 154 days in the non-broken screw group and 268.6 days in the broken screw group (p<0.05). The average AOFAS midfoot scale was 77.4 in the non-broken screw group and 74.2 in the broken screw group. The most commonly damaged portion was the first tarsometatarsal (Lisfranc) joint. Conclusion: Treatment with screws and K-wires was effective in patients with fracture dislocation of Lisfranc joint. The appropriate time for screw removal should be considered.

Purpose: To investigate the measured values of the talus in Koreans. Materials and Methods: We measured 88 tali from 44 cadavers that have been donated between December 2012 and December 2015. Of the cadavers, 27 were male and 17 were female. Their mean age was 73 years. The length and width of the talus were measured using a digital goniometer and vernier caliper. Results: The values of cadaveric measurement, mean maximal width and length, width and length of the dome anterior, width and length of the posterior facet, height and length of the trochlear medial facet, and height and length of the trochlear lateral facet were $43.6{\pm}2.6mm$, $56.5{\pm}3.3mm$, $32.5{\pm}2.0mm$, $42.2{\pm}2.7mm$, $22.2{\pm}2.2mm$, $34.7{\pm}2.0mm$, $15.3{\pm}1.3mm$, $33.3{\pm}2.9mm$, $25.3{\pm}3.3mm$, and $30.8{\pm}2.4mm$ for men and $38.9{\pm}1.6mm$, $53.6{\pm}2.4mm$, $27.9{\pm}2.1mm$, $37.4{\pm}3.2mm$, $20.6{\pm}0.8mm$, $31.9{\pm}1.2mm$, $13.6{\pm}2.6mm$, $28.4{\pm}2.5mm$, $24.9{\pm}2.1mm$, and $28.9{\pm}1.4mm$ for women, respectively. The size of the talus showed an accuracy of 86% when anteroposterior diameter was greater than 59 mm. A difference in the size of the right and left talus was not observed. The mean inclination and declination angles were $24.4^{\circ}{\pm}4.2^{\circ}$ and $28.2^{\circ}{\pm}5.4^{\circ}$ for men, and $24.6^{\circ}{\pm}3.6^{\circ}$ and $24.7^{\circ}{\pm}6.7^{\circ}$ for women (p=0.980, p=0.018), respectively, at least $15^{\circ}$, which showed a big difference for every object up to $37^{\circ}$. Conclusion: This paper, to the best of our knowledge, is the first study to measure the talus in Koreans. There were differences by gender and ethnicity in the in measured talus values. The measurements were smaller than European-Americans and greater than Japanese.

후경골건 감입에 의한 족관절 골절-탈구의 정복 실패: 증례 보고

하동준,곽희철,정동우,노상명,Ha, Dong-Jun,Gwak, Heui-Chul,Jeong, Dong-Woo,Roh, Sang-Myung 대한족부족관절학회 2014 대한족부족관절학회지 Vol.18 No.4

Fracture and fracture-dislocation of the ankle may be caused by a variety of mechanisms. In addition to the fracture, injury of soft tissue such as ligaments, tendons, nerves, and muscles may occur. Among these, tibialis posterior tendon injury is difficult to identify due to swelling and pain at the fracture site. There is no clear finding in radiological examination, therefore, it is found during surgery. In this case, irreducible fracture-dislocation of the ankle due to tibialis posterior tendon interposition was observed after the primary operation. The authors obtained satisfactory results in performance of a secondary operation assisted with arthroscopy.

하동준,김창완,서승석,조일제,Ha, Dong-Jun,Kim, Chang-Wan,Seo, Seung-Suk,Cho, Il-Je 대한정형외과스포츠의학회 2009 대한정형외과스포츠의학회지 Vol.8 No.2

목적: 내측 반월상 연골판 후각부 파열 치료 결과에 영향을 미치는 요인들에 대해 알아보고자 한다. 대상 및 방법: 내측 반월상 연골 후각부 파열로 진단받고, 관절경적 시술을 받은 47명을 대상으로 하였다. 환자의 연령, 대퇴경골각, 골주사 검사 결과, 수술 방법 및 파열 양상에 따른 술후 임상적 결과를 Lysholm 및 Tegner 활동 점수를 이용하여 평가하였다. 결과: 환자의 나이는 수술 결과에 영향이 없으며, 술전 외반 4도 이상의 대퇴경골각을 가지거나, 술전 방사성 동위 원소 검사에서 정상 소견을 보이는 경우 좋은 예후를 기대할 수 있었다. 수술 방법의 차이, 즉 반월상 연골판 제거술 혹은 봉합술 여부에 따른 치료 결과의 통계적 차이는 없으며, 파열 양상에 따른 결과 차이 또한 통계적 의의는 없었다. 결론: 내측 반월상 연골판 파열의 치료에 있어 만족한 결과를 얻기 위해 다양한 요인들을 고려해야 하며, 특히 술전 시행한 골주사 검사는 반월상 연골판 파열부 및 그 주변 골, 연골의 상태를 반영하여 술후 예후를 예측할 수 있는 좋은 평가 방법으로 사료된다. Purpose: The purpose of this study was to evaluate the factors affecting the treatment results of medial meniscus posterior horn tear. Materials and Methods: Forty seven patients who had been performed the arthroscopic surgery for medial meniscus posterior horn tear were enrolled in this study. We analyzed the clinical outcomes with Lysholm score and Tegner activity score in accordance with the factors such as patients' age, tibiofemoral angle, uptake in bone scintigraphy, surgical methods and patterns of meniscal tears, respectively. Results: The patients' age didn't affect to the results, but the preoperative tibiofemoral angle over valgus $4^{\circ}$ and the preoperative normal uptake in scintigraphic assessment showed a positive influence on the clinical outcomes. The partial meniscectomy and repair in surgical methods had no statistically significance. In addition, the pattern of meniscal tear did not have an effect on the clinical results. Conclusion: We can conclude that many factors should be considered to get satisfactory results. Among them, preoperative bone scintigraphy may be a good assessment factor for the postoperative prognosis, reflecting the condition of meniscal tear and the periarticular bone and soft tissue.
