본 논문에서는 Telos Device를 이용한 검사 시 인가한 daN 힘의 차이와 무릎의 안정성에 관여하는 근육들의 개인차에 따른 전방십자인대의 동요 정도에 대해 연구하고자 한다. Telos Device를 이용한 Lachman Test로 검사하였으며, 오른쪽과 왼쪽을 각각 0, 15, 30 daN, 운동부하 후 30 daN의 힘으로 변화하며 검사하여 전방십자인대의 변화를 측정하였다. 근육량 측정은 CT(Computed Tomography)를 이용하였으며, 힘줄(tendon)을 피해 근육을 측정하기 위해 무릎뼈(patella) 상방 8 cm의 위치를 검사하였다. 전방십자인대(Anterior Cruciate Ligament)의 변화 정도는 Piview의 Caliper 기능을 이용하여 측정하였으며, 근육량은 CT 단면 영상을 Image J 프로그램을 이용하여 지방을 제외한 뼈와 근육의 면적을 측정하였다. 측정값들은 SPSS Ver. 18을 이용하여 결과 값을 얻었다. Telos Device 로 인가하는 힘의 변화에 따라 전방십자인대의 동요 정도를 측정한 결과 오른쪽과 왼쪽 모두 15 daN과 30 daN의 힘을 인가하였을 때 통계적으로 유의한 무릎 동요의 차가 발생하였으며(p<0.05), 30 daN과 운동부하 후 30 daN에서의 동요 정도는 유의한 차이를 보이지 않았다(p>0.05). 근육면적의 차이와 전방십자인대의 동요 정도와의 상관관계에서 15 daN의 압력에서 오른쪽 r=-0.45, 왼쪽 r=0.44로 음의 상관관계를 보였다(p<0.05). Telos Device에 인가하는 힘의 정도에 따라 전방십자인대의 동요는 커지는 것으로 분석되며, 또한 개인의 근육량의 차이에 따라 전방십자인대의 동요 정도에도 차이를 보이는 것으로 분석된다. 따라서 개인의 근육량의 차이에 따라 Telos Device에 인가되는 힘도 변화되어야 하는 것으로 사료된다.

The purpose of this case study is to show a case of acute posterior cruciate ligament(PCL) complete injury improved by conservative acupuncture therapy. The patient was treated for 100 days. The patient received deep interarticular electroacupuncture(EA) stimulation at S35, LE200, LE211 and treated by other acupoint stimulation, herb medication, cupping, physical treatments and exercise. We evaluated through MRI and Lysholm knee score. We suggest to treat acute posterior cruciate ligament(PCL) injury with acupuncture therapy meaning conservative therapy and would like to research acupuncture treatment plan for the further treatments.

The anterior cruciate ligament(ACL) is an important stabilizer of knee joint. The ACL injury of knee is common and a serious ACL injury leads to ligament reconstruction surgery. Gait analysis is essential to identify knee condition of patients who display abnormal gait. The purpose of this study is to evaluate and classify knee condition of ACL deficient patients using a nonlinear dynamic method. The nonlinear method focuses on understanding how variations in the gait pattern change over time. The experiments were carried out for 17 subjects(l2 healthy subjects and five subjects with unilateral deficiency) walking on a motorized treadmill for 100 seconds. Three dimensional kinematics of the lower extremity were collected by using four cameras and KWON 3D motion analysis system. The largest Lyapunov exponent calculated from knee joint flexion-extension time series was used to quantify knee stability. The results revealed the difference between healthy subjects and patients. The deficient knee was significantly unstable compared with the contralateral knee. This study suggests an evaluation scheme of the severity of injury and the level of recovery. The proposed Lyapunov exponent can be used in rehabilitation and diagnosis of recoverable patients.

A ganglion cyst is a soft tissue mass that is surrounded by a dense connective-tissue capsule. The capsule is filled with a viscous fluid that is rich in hyaluronic acid and other mucopolysaccharides. But, Ganglion cysts in the knee joint are rare. There are very few case reports of ganglion cysts related to the surface of the anterior cruciate ligament, Posterior cruciate ligament and medial meniscus. We are reporting a case of a ganglion cyst in the anterior aspect of the anterior cruciate ligament accompanying with discoid lateral meniscus in the right knee of a 46-year-old woman without any history of trauma. The cyst and discoid lateral meniscus were treated successfully with arthroscopic excision and partial meniscectomy.

육상 선수나 격투기 선수들에게서 전족부 손상은 흔한 편이나 족무지 지간 관절은 해부학적 안정성으로 인해 관절 측부 인대손상은 매우 드문 것으로 알려져 있다. 특히 스포츠 손상에 의한 지간 관절의 만성 불안정성에 대해서는 국내외적으로 보고가 극히 적어 저자들은 대학 태권도 선수에서 족무지 지간 관절의 진구성 외측부 인대 파열에 기인한 만성 무지 내반 불안정성에 대하여 수술적으로 치료하여 좋은 결과를 얻었기에 이를 보고하고자 한다.

The purpose of this case study was to use Korean medicine to treat posterior cruciate ligament avulsion fracture. The patient suffered left knee pain resulting from an avulsion fracture and was hospitalized for 59 days and treated with acupuncture and traditional Korean medicine. The effect of the treatment was evaluated using the Numerical Rate Scale, the Western Ontario and McMaster universities Osteoarthritis Index, and the European Quality of Life Five Dimensions. Following treatment of the pain in the left knee, scores for Numerical Rate Scale, Western Ontario and McMaster universities Osteoarthritis Index, and European Quality of Life Five Dimensions were improved. This study suggested that Korean Medicine could be an effective treatment for posterior cruciate ligament avulsion fractures. Further studies are needed to substantiate this conclusion.

45% of the sports accidents is the knee damage and the representative case is the damage of an Anterior Cruciate Ligament (ACL) and the Posterior Cruciate Ligament(PCL). Although the past different views of ACL reconstruction comes to an agreement, the disputes of PCL is remained yet. The most important engineering approach for these various surgery techniques is accurately to understand and to evaluate the fatigue behavior depending on the stress flow and the stress distribution under the allotted load and the cyclic load, which are caused by the graft fixing device, the proximal tibia of the PCL reconstructing structure. 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 relationships between the slippage, the extension ratio, and the slippage ratio by the heel bone fixing method and the soft tissue fixing method of the Achilles tendon were also defined. This research will be the essential data to help the resonable operating techniques for the next PCL reconstruction.

A torn anterior cruciate ligament(ACL) is the most common serious ligamentous injury to the knee joint. The incidence of ACL tears seems to be increasing, at least partly as a result of the increasing participation of individuals of all ages in high-risk sports. The most commonly used graft source for ACL reconstruction is the autogenous bone-patellar tendon-bone graft unit. Despite a good success record. postoperative complications, such as infection, patellar contracture/patellar baja, patellar fracture, rupture of the patellar tendon, graft failure without reinjury, can occur following ACL surgery. The purpose of this paper is to provide guidelines regarding the key points of the reconstructive procedure in a sequence and how to prevent or minimize the complications that can follow ACL reconstructive surgery. We want this knowledge can help orthopaedic surgeons to understand the reasons for previous and current successes and failures of reconstruction of the ACL, and it can help them to plan the care of patients who have an injury of the ligament.
