슬관절 후방십자인대 손상이 의심되는 응급환자의 슬대퇴 관절을 촬영하기 위한 보조기구를 제작하고 그 유용성을 평가하고자 하였다. 실험 방법은 2006년 1월부터 2006년 12월까지 슬관절 손상으로 을지대학병원에 내원한 환자 중 후방십자인대 손상 의증으로 Knee post stress view와 Knee Merchant view 그리고 보조기구를 이용한 Knee post stress view를 모두 촬영하고, 무릎 MRI(Knee MRI)검사를 시행한 17명을 대상으로 하였다. $170{\times}50{\times}70\;cm$의 보조 기구를 제작하였으며 Knee post stress view와 보조기구를 이용한 Knee Seo's view에서 경골의 후방전위 간격을 측정하여 유용성을 평가하였다. 그 결과 보조기구를 이용한 Knee Seo's view가 기존의 Knee post stress view에 비해 후방십자인대 손상 여부의 판단이 더 정확한 것으로 나타났다. 기존 촬영법의 경골 후방전위 간격 차이는 $6.17{\pm}3.04$이었으며, 보조기구를 이용한 촬영법의 경골 후방전위 간격 차이는 $8.74{\pm}4.47$이었다. 결론적으로 자체 제작 보조기구를 이용한 슬대퇴 관절 촬영법은 기존에 슬관절면 손상을 보기 위한 Knee Merchant view와 후방십자인대 손상을 보기 위한 Knee post stress view를 동시에 1회 촬영으로 끝낼 수 있었으며, 기존의 Knee post stress view 보다 후방십자인대 손상 여부를 보다 정확하게 알 수 있었다. 따라서 후방십자인대 및 슬대퇴 관절 손상이 의심되는 응급환자에서 talometer나 MRI 검사의 선행 검사로 유용하게 이용될 수 있을 것으로 사료된다.

In the case of Posterior Cruciate Ligament (PCL), the most frequent mechanism is the dashboard injury, which is directly pressurized to the anterior of the proximal tibia in the state of the knee hyperflexion. The PCL associated ligament damage happens when the posterior injury, the varus, the valgus, the hyperextension and the severe vagus torque are out of the critical value of PCL. After the successful operation cases of Anterior Cruciate Ligament (ACL) reconstruction using the allograft were informed from 1986, a number of results kept over the maximum 10 years were reported. Unfortunately, PCL reconstruction are crowded the surgery techniques such as the graft, the tibia fixing method, the fixation device, the location of the femoral tunnel, the number of the graft bundles and PCL reconstruction to access to the stability of the normal joint is being developed. Therefore, this study is the basic research of these above facts. The current transtibial tunnel surgery using the cadaveric Achilles tendon grafts is chosen for the various PCL reconstruction. The initial extension of the Achilles tendon by the fixing device and its location under the cyclic loading, were observed.

Authors report one patient of concurrent fracture of medial malleolus and rupture of deltoid ligament. To the author's knowledge, combined failure of both structures has not been previously reported in Korea. Injury mechanism was classified into pronation -abduction type according to Lauge-Hansen classification. Plain radiograph revealed trimalleolar fracture and posterior ankle dislocation. MRI showed complete rupture of both deep and superficial layer of the deltoid ligament. In conclusion, therefore, concurrent rupture of deltoid ligament should be considered for the surgical treatment in trimalleolar ankle fracture with posterior ankle dislocation resulted from pronation-adduction injury.

목적: 전방십자인대 파열 시 손상 시기와 원인에 따른 동반 손상의 빈도 및 양상을 비교하여 평가하고자 하였다. 대상 및 방법: 전방십자인대 재건술을 시행하였던 547례의 슬관절을 대상으로 손상 시기(급성과 만성), 손상 원인(운동과 비운동) 및 운동 종목에 따라 동반 손상의 빈도와 양상을 후향적으로 비교 분석하였다. 결과: 손상 시기에 따라 수상 후 3개월 이내는 급성으로, 3개월 이후는 만성으로 분류하였으며 급성 손상군에서 내측 측부 인대 손상 및 골 좌상이 많았고 만성 손상군에서는 내측 및 외측 반월상 연골 손상의 빈도가 유의하게 높았다(p=0.014, 0.029). 연골 손상은 급성 손상군의 경우 대퇴 활차부에(p=0.027), 만성 손상군의 경우 대퇴 내과에 많았고(p=0.011), Grade I, II의 연골 손상은 급성 손상군에(p=0.016), Grade III, IV의 손상은 만성 손상군에(p=0.017) 많았다. 손상 원인에 따른 차이로는 운동 손상군에서 외측 반월상 연골 손상의 빈도가 높았으며(p=0.035) 비운동 손상군에서 대퇴 내과의 연골 손상이(p=0.010) 유의하게 많았다. 운동 종목 별로는 스키에서 내측 측부 인대 손상이(p=0.005), 체조에서 연골 손상이(p=0.017) 다른 종목에 비해 많았다. 결론: 내측 및 외측 반월상 연골 손상, 심한 연골 손상의 빈도는 만성 손상군에서 높았고 손상 원인과 운동 종목에 따른 동반 손상의 빈도 및 양상에 차이가 있었다.

Objectives: The purpose of this study is to evaluate the effect of the burning acupuncture therapy and exercise therapy on the internal derangement of knee with patella tendon and posterior cruciate ligament injury. Methods: Burning acupuncture therapy was administered three times and exercise therapy was administered during 4 weeks. The improvement of clinical symptom was evaluated by VAS(visual analogue scale) and KOOS(knee injury and osteoarthritis outcome score). Results: After treatment, the patient's VAS score was reduced to 0 pant. The KOOS score of pain, symptom, ADL, sport/rec, QOL(quality of life) improved from 28 to 75, from 36 to 71, from 22 to 65, from 0 to 15, from 25 to 38 respectively. Conclusions: Burning acupuncture therapy and exercise therapy fer internal derangement of knee with patella tendon and posterior cruciate ligament injury was effective. Although this case presented valuable result, further research is encouraged to confirm the effectiveness of this treatment with large number of patient.

A 4 years old male mixed breed dog, which weighed 25.5 kg, referred to Veterinary Teaching Hospital at College of Veterinary Medicine in Chonnam National University, because of chronic hindleg lameness. Click sound by flexion and extension of stifle joint, positive reaction by cranial drawer movement, fat pad sign and tibial position in cranial drawer position on the lateral radiographic view, medial patellar luxation (grade II), and lameness score 2.5 at standing and 2 at walking in right hindleg were showed. Under general anesthesia with enflurane, after medial arthrotomy, it was performed to remove remnants of cranial cruciate ligament and torn medial menisci and joint closed. In modified retinacular imbrication technique, one lateral fabellar/tuberosity suture, one medial fabellar/tuberosity suture, and one imbrication suture adjacent to the patella were placed. At 9 days after operation, lameness score 0 was observed and general condition was excellent.

The natural history of the anterior cruciate ligament(ACL)-deficient knee remains controversial. although numerous investigation have tried to ascertain the course that the knee would follow once the ACL has lost functional integrity. An extensive review of the literature performed according to symptoms. physical examinations, associated surrounding tissue injuries. returns to activity level and radiological changes in the knee joint. An active individual with a non-functioning ACL was susceptible to injury to the menisci and deteriorate the articular cartilage, followed radiographic changes. An activity levels in general also changed after injury. The most common symptom was pain. But instability varied in these individuals. Conclusively we believe that all these factors will eventually, if not initially, result in a symptomatic knee. which will result in significant limitations to the individual's desired level. So we recommend an aggressive approach in person who desired to return to a relatively active life style in young person as well as in middle aged individuals who have significant symptomatic ACL deficient knee.

Extraordinary properties of nanocomposites make them a primary replacement for many conventional materials. Anterior cruciate ligament (ACL) reconstruction, which is a frequent surgery in sport activities, is one of the fields in which nanocomposites could be utilized. In the present study, the mechanical properties of different porous scaffolds made from graphene nano-composites are presented ad load bearing capacity of these materials is calculated using finite element method. The numerical results are further compared with experimental published data. In addition, several geometrical and material parameters are analyzed to find the best configuration of nanocomposite scaffolds in reconstruction of ACL. Moreover, coating of detoxification chemicals are extremely easier on the nano-structured materials than conventional one. Detoxification potential of nano-composites in the injured body are also discussed in detail. The results indicated that nano-composite could be successfully used in place of auto- and allografts and also instead of conventional metallic screws in reconstruction of ACL.
