목적: 자가 슬괵건 또는 자가 슬개골건골을 이용한 관절경적 전방십자인대 재건술을 전향적으로 시술하고 그 결과를 비교하고자 하였다. 대상 및 방법: 2004년 1월부터 2007년 12월까지 총 50명의 환자를 대상으로 전향적으로 연구하였으며, 한 명의 시술자에 의해 자가 슬괵건과 자가 슬개골건골을 각각 순차적으로 교대로 사용하여 전방십자인대 재건술을 시행하였다. 추시 기간은 양 군 모두 평균 38개월(범위 25~58개월) 이었다. 술전과 최종 추시 시에 Lachman 검사 및 Pivot shift 검사를 실시 하였고, 환자의 주관적 기능은 Lysholm 점수와 Tegner 활동도 점수를 조사하였으며, 전방 안정성은 Telometer를 사용하여 전방 전위의 정도를 객관적으로 평가하였다. 결과: 최종 추시 시 자가 슬괵건을 사용한 군(1군)과 자가 슬개골건골을 사용한 군(2군) 간의 비교에서 Lachman 검사는 음성 또는 경도의 양성이 각각 24명씩이었으며, Pivot shift 검사 또한 1군에서 22명 그리고 2군에서 21명이 음성으로 나타남으로서 두 군간에 통계학적인 차이가 없었다(P=0.18). 최종 추시 시 시행한 환자의 주관적 만족도 검사에서 Lysholm 점수는 1군이 94.6점 이었고, 2군이 92.3점이었으며, Tegner 활동도 점수도 각각 8.5점과 8.1점으로 나타나 양군간의 통계학적 차이는 없었다(P=0.23). 20도 굴곡위에서 Telometer를 사용하여 측정한 전방 전위 정도는 5 mm 미만이 1군에서 24명, 2군에서 23명이었다. 결론: 자가 슬괵건 또는 자가 슬개골건골을 사용한 전방십자인대 재건술의 Lysholm 점수와 Tegner 활동도 검사상 1군에서 약간 더 양호한 결과를 나타내었으나 통계학적으로 유의한 차이는 없었다. Purpose: The purpose of this prospective study is to compare the results of arthroscopic reconstruction of ACL using autologous hamstring tendon (Group 1) and autologous bone patella tendon bone (Group 2). Materials and Methods: From Jan. 2004 to Dec. 2007, fifty patients were analyzed in this study. A single surgeon performed the ACL reconstruction with autologous hamstring tendon (25 patients) and autologous bone patella tendon bone (25 patients) alternatively each other. The mean follow up period of two groups was 38 months (range 25~58 months). We evaluated the result of Lachman test, Pivot shift test as a physical examination and Lysholm score, Tagner activity scale as patients' satisfaction and functional status and Telometer for anterior instability of each groups at the time of final follow up. Results: In final results, negative or mild positive findings on Lachman test were 24 out of 25 cases (equally) in each groups.) Twenty two cases in the Group 1 and 21 cases in the Group 2 were negative on Pivot shift test. Lysholm scores mark 94.6 points in group 1 and 92.3 points in group 2 at the final follow up and Tegner activity scales mark 8.5 points (Group 1) and 8.1 points (Group 2) at the time of last follow up and there were no differences between the two groups statistically. The numbers of patients who have less than 5 mm of anterior translation of tibia under telometer at 20 degrees of knee flexion are 24 cases in group 1 and 23 cases in group 2. Conclusion: The overall improvements of clinical scores (Lysholm scores and Tegner Activity scales) of the group 1 were a little bit superior to those of the group 2, but there were no significant statistical difference between two groups.

In making an attempt to examine the fitness training effects on coordination and strength of preschool children, four groups of 5 year old children consisted of two experimental groups of three children for each sex and two controls of similar composition were employed. Experimental groups were subjected to one circuit of various physical activities which lasted for 30-40 minutes per day for 5 weeks. Measurements obtained in continuous tapping, whole body reaction time, grip strength and vertical jumping during those five weeks except in Sundays and national holidays were analysis method and were compared with the results of physical fitness tests. The results were summarized as follows: (1) The analysis of daily fluctuations in physical fitness test performances for five weeks showed that each subject had specific pattern of fluctuations in terms of different periods, amplitudes and linear trend. (2) When compared the mean amplitudes of daily fluctuations in physical fitness tests with the mean values of increase from pre-training values, tapping was found to be the only variable with significant differences between them.

Purpose: To evaluate the clinical feature and the results of the treatment of Lisfranc joint fracture/dislocation with limited open reduction, pin fixation and Ilizarov external fixation. Materials and Methods: From June 2001 to May 2003, six patients with Lisfranc fracture/dislocation were treated. The average periods of follow-up was 23 months. After limited open reduction on the second tarso-metatarsal joint, we performed pin fixation of the above joint. On the other Lisfranc joint fracture/dislocation, closed reduction and the application of Ilizarov external fixator was done. This rigid system produced the early partial weight bearing and joint motion of the injured foot and ankle joint. The parameters used were radiographic evaluation, patient's clinical assesment and the AOFAS midfoot score. Results: We used the Myerson's criterier to evaluate the radiographic result. All cases could be achieved more than nearly anatomical reduction. Three cases of excellent and 3 cases of good result could be obtained in the evaluation of the patient's clinical assesment. The average AOFAS midfoot score was 87.2 ($76{\sim}95$) points. Conclusion: The treatment using Ilizarov external fixation on Lisfranc joint fracture/dislocation can be another useful method.

안길영,남일현,문기혁,이영현,최성필,유종연,Ahn, Gil Yeong,Nam, Il Hyun,Moon, Gi Hyuk,Lee, Yeong Hyun,Choi, Seong Pil,Yoo, Jong Yeon 대한관절경학회 2013 대한관절경학회지 Vol.17 No.1

목적: 전방십자인대 재건술을 시행할 때 경골 부착 부위의 잔류 조직 보존 방법이 이식 인대의 활막화에 미치는 영향을 2차 관절경 소견을 통해서 알아보고자 하였다. 대상 및 방법: 전방십자인대의 급성 파열에 대하여, 4가닥의 자가 슬괵건을 이용하여 대퇴 부 흡수못 형태인 RigidFix$^{(R)}$을 사용하여 전방십자인대 재건술을 시행한 환자 63예 중, 술후 1년 이후에 금속 나사못 제거를 시행 할 때에 2차 관절경 수술로 이식건의 상태를 확인할 수 있었던 19예를 대상으로 하였다. 수술 당시 파열된 전방십자인대의 경골 부착부에서 파열 인대의 잔류 조직이 5 mm 이하로 남은 경우를 1군(5예), 6-10 mm사이에 남은 경우를 2군(8예), 11 mm 이상 남아있는 경우를 3군(6예)로 나누었다. 술후 1년에서 2년 사이에 시행한 2차 관절경 소견에서 이식 인대에 활액막이 덮힌 정도를 조사하였다. 결과: 2차 관절경 수술에서 활막화(synovialization)된 정도는 1군에서 평균 55.4%, 2군에서 평균 77.9%, 3군에서는 평균 89.7%이었다. Lysholm 점수와 Tegner 활동도 점수는 술전 평균 74.2점과 7.3점에서 최종 추시 때에 94.1점과 8.5점으로 호전되었다. 결론: 전방십자인대 재건술을 시행할 때에 전방십자인대의 경골 부착 부위에 파열된 인대의 잔류 조직을 많이 남겨 둘수록 이식건의 활막화 면적(비율)이 넓어짐을 확인하였고, 남겨둔 조직의 양과 활막화 면적은 비례 하였다. 이는 이식건의 생착과 고유 감각기능의 보존에 좋은 영향을 미칠 것으로 사료된다. Purpose: The purpose of this study is to evaluate the effect of preservation of the tibial remnant on the synovialization of graft tendon after the reconstruction of anterior cruciate ligament (ACL) based on the second look arthroscopic findings. Materials and Methods: From May 2005 to May 2012, among sixty three patients having ACL reconstruction with the four-strand hamstring using a bioabsorbable cross pin (RigidFix$^{(R)}$) for the femoral tunnel, nineteen patients who had second look arthroscopy were analyzed. We classified them into three groups according to the tibial remnant of the torn ACL for arthroscopic findings. Group 1 had less than 5 mm of a remnant tissue, Group 2 had from 6 mm to 10 mm of it, and Group 3 had more than 11 mm. We estimated the percentage of synovial coverage on the graft tendon during second look arthroscopy. We evaluated Lysholm score and Tegner activity score preoperatively and in the last follow-up. Results: At the time of ACL reconstruction, the mean length of preserved tibial remnant of torn ACL was 2.3 mm in Group 1, 7.4 mm in Group 2, and 13.7 mm in Group 3. In the second look arthroscopy, the average percentage of synovial coverage was 55.4% in Group 1, and 77.9% in Group 2, and 89.7% in Group 3. Lysholm score and Tegner activity score improved from 74.2 and 7.3 preoperatively to 94.1 and 8.5 in the last follow-up. Conclusion: The preservation of tibial remnant of torn ACL influenced the synovial coverage of the graft tendon and the volume of preserved remnant in accordance with the surface of synovial coverage. It would have a good effect on graft healing and preservation of proprioceptive function.

This study was designed to investigate a minimum sample size requiring to identify characteristics of various variables in potentially implicated social phenomenon in accordance with the purpose of many studies on leadership of psychological tests. So, based on the multidimensional model of Chelladurai(1978), The basic hypothesis of this study was established after ascertaining the behavioral scales of sports leadership developed by Chelladurai& Saleh(1980) as presuppositionally validated theoritical model. This model identifies whether the stability of factorial structure through monte carlo simulation was ifluenced or not by variables in gender and sport types(team game and individual game). Conclusion obtained from the result of this study was as followed : after excluding factor 5 reducing internal agreement of completed model consisted of reversed items in previous study as well study on gender and sport types, it appear that testified factorial score of reduced model was stable rather than total factorial structure of questionare. Also, in the result of mainly analyzed model index according to sample size, full model and reduced model was some different but both models was more suitable as the number of case was increased, but this study show that some problems must basically be testified in the future. The number of cases. In gender and sport types, the number of cases was lack on parameters of population and representation of samples in team sport and women. Also, First, this study was accomplished to test whether how many the number of case was necessary to identify elit athelets or not. second, a limited item contents in this study was firstly assumed to ascertained circumstance of population and limit items as 40. a minimum sample size for this study has some closing relationship on the number of parameters assumed. Also, this study was additionally necessary to perform investigation on sample size and the number of items to ascertain reliability.
