Less has been written about the PCL than the ACL. There has, however, been an increasing amount of the interest in the PCL recently. Surgical reconstructions using grafts are often performed. However, these procesures often fail to provide long-term stability and function. Graft attachment sites are critical determinants of success in the PCL reconstruction. The clinical literature contains conflicting recommendations for graft attachment sites. We present a review of the isometry of the PCL.

Atherosclerotic giant aneurysm of the common femoral artery is rare. Because the patients who lose timing of the operation face amputation or death, the surgical treatment must be performed at the proper time. A 72-old man was admitted to the hospital because of a 20-days history of pulsatile growing mass on his left groin. After the diagnosis of giant aneurysm of the common femoral artery by computerized tomography and digital subtraction angiography, an emergent operation was performed. Both deep and superficial femoral arteries were successfully reconstructed with Gore-tex grafts after aneurysmectomy. The pathology of the aneurysm was proved to be atherosclerosis.

A 60-year-old man with a history of gunshot vascular injury on the right inguinal area, and this happened in the military service 40 years ago, was admitted to our hospital with claudication and dyspnea on exertion. The patient was diagnosed with a chronic traumatic femoral arteriovenous fistula. The patient underwent a successful operation for arteriovenous fistula closure with bovine pericardium and for femoropopliteal bypass with using a right greater saphenous vein graft. The patient is well at 14 months after the operation.

본 연구는 교각운동시 불안정한 지지면과 안정적인 지지면을 제공하여 체간 및 하지의 근 활성도의 변화를 알아보고자 하였다. 이 연구의 대상자는 20대 남, 여 14명이었다. 실험방법은 일반적 교각자세와 다이나믹 에어쿠션을 이용한 교각자세를 실시한 후에 무선 8채널 표면근전도 검사기를 이용하여 체간부의 척추기립근, 복직근, 대퇴의 대퇴직근, 외측 슬괵근, 하퇴부의 전경골근, 비복근 외측두에서 근활성 정도를 측정하였다. 체간부의 척추 기립근, 대퇴이두근, 가자미근은 불안정한 지지면에서 근활성도가 높게 나타났다(p<.05). 따라서, 교각운동에서 불안정한 지지면의 제공은 신체의 배측에 위치한 근육의 활성화를 나타내어, 교각운동시 지지면의 안정성의 변화만으로도근육활성도의 변화가 가능함을 알 수 있었다.

Falling related injuries are categorized as the most serious and common medical problems experienced by the elderly, hip joint fracture, one of the most serious consequences of falling in the elderly, occurs in only about 1% of falling. Nevertheless, hip fracture accounts for a considerable part of the disability, death, and medical costs associated with falling. In this study, we considered the impact angle and displacement rate in falling as another factor affecting femoral strength. Using a fresh-frozen human femur, we developed system to simulate the falling condition and then conducted the experiments changing the impact angle (0$^{\circ}$, 15$^{\circ}$, 30$^{\circ}$) of proximal femur. Also, in order to analyze the relative risk due to falling to normal situation in proximal femur, we did the static test simulating the two-legged stance condition. The results showed that the change in impact angle affected the strain distribution in proximal femur, and that a large deformation in femoral neck than in other sites. Furthermore despite low impact velocity, a large deformation in proximal femur occurred in the impact test and different strain distribution was observed compare to the static case.

The aims of this study are to investigate the walking intention detection of a rollator based on Infraed (IR) sensor measuring knee joint anterior displacement and leg muscle activities. We used Active Walker attached IR sensor to measure the knee joint anterior displacement and EMG signal of leg muscles(rectus femoris, biceps femoris, tibialis anterior, gastrocnemius) were taken by Delsys bagnli-8ch. Subjects were eight healthy males(age $23.7{\pm}0.5years$, height $175.4{\pm}2.3cm$, weight $70.6{\pm}5.6kg$) and they were involved in experiments which had been proceeded 30 minutes a week, during 3 weeks. This system indicates that the knee joint anterior displacement had the distinction increases according to the gait slope and velocity. We showed the increase of the femoral muscle activities along the anterior tilt and the increase of the crural muscle activities along the posterior tilt.

A 49-year-old male was found unconscious at his accommodation and visited the emergency room. He was on antipsychotic and antidepressant drugs (vortioxetine hydrobromide, mirtazapine, sertraline hydrochloride, quetiapine, and alprazolam) for schizophrenia and major depression. At the time of discovery there were signs of overdose of the drugs around the patient. A physical examination revealed, pain, pallor, and edema in the left buttocks and lateral thigh. Active ankle movements below the left ankle were not possible and sensations in the tibia and peroneal nerves were lost. The pressure in the buttock compartment was measured at 42 mmHg. Magnetic resonance imaging revealed edema and high intensity signals in the left hip muscles and surrounding soft tissue. An emergency fasciotomy was performed and partial restoration of the lower extremity sensation and muscle strength were achieved after 24 hours.

욕창의 발생부위에 따른 수술방법 중 천골부 욕창의 치료에는 천골절골이 필요한 깊은 경우에는 대둔근피판술이, 갚지는 앓으나 광범위한 욕창일 경우에는 하둔대퇴피판술이 가장 성적이 좋았다. 대전자부 욕창의 치료에는 대퇴근막장근근피판술이 가장 성적이 좋았으며, 슬관절부 욕창의 치료에는 비복근판술 후 피부이식방법이 좋은 결과를 초래하였으며, 종골부 창상치료에는 발꿈치의 외후면 재건시는 lateral calcaneal flap이 좋으며, 종골절골이 필요치 않은 heel pad 재건시는 족저부 근막피판술이, 종골절골이 필요한 heel pad 재건에는 족지단골근근판술이 가장 좋은 성적을 가져 왔기에 문헌고찰과 함께 보고하는 바이다.

Since the extent of use of musculoskeletal ultrasound in orthopaedic surgery is expanding, popliteal block(sciatic nerve block) and femoral nerve block(saphenous nerve block) are easily and safely performed without complications such as nerve injury or incomplete block. Also, due to the expanding use of ultrasound, orthopaedic surgery of not only foot but also ankle and lower leg could be done without general anesthesia or spinal anesthesia. We describe a detailed technique for ultrasound-guided femorosciatic nerve block based on the experience over 120 cases.

Synovial sarcomas of the hand are rare. It should be treated with wide resection. In the cases of soft tissue sarcomas of the hand, functional reconstruction must be considered. We report 46-year-old male patient with synovial sarcoma of the right thenar muscle which was treated with unplanned intralesional resection at outside hospital, that has been treated with wide resection including trapezium and first metacarapl bone then, reconstructed with nonvascularized fibular graft and anterolateral thigh free flap.
