Purpose: Meniscal injuries are very common sports problems and indications for knee surgery. We analyzed the effectiveness of joint line tenderness retrospectively. Materials and Methods: From May 2005 to June 2006, 76 knees which were diagnosed meniscal injury and performed arthroscopic surgery by same surgeon at military hospital were included. We analyzed sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of joint line tenderness in meniscal diagnosis. Results: The joint line tenderness gave such results (78.8%, 32.6%, 52.6%, 47.3%, 66.7% for sensitivity, specificity, accuracy, positive predictive value, negative predictive value respectively). We got similar results in analyses with medial meniscal lesion, lateral meniscal lesion, and combined instability patients. Conclusion: The joint line tenderness is a easy and comfortable maneuver but, it's effectiveness is low when it is used lonely The composite examinations including MRI and diagnostic arthroscopy for meniscal injuries of the knee perform much better than joint line tenderness alone.

Complications and sequelae of the laryngeal trauma are respiratory difficulties, edema or swelling, cellulitis or abscess, fistula, perichondrium and chondritis, chronic laryngeal stenosis, vocal cord paralysis, decannulation difficulty, and impaired voice production etc. Generally, the treatment of laryngeal injuries consists of initial tracheostomy for adequate airway and later surgical intervention for its complications and sequelae. Recently, authors experienced a case of closed laryngeal injury with thyroid cartilage fracture, left vocal cord paralysis, swallowing difficulty and right clavicular fracture owing to automobile accident. With reconstructive surgery for thyroid cartilage fracture, we established an adequate airway, improved swallowing function and better voice production.

The purpose of this paper is to review changes in articular cartilage properties from the joint immobilization. Joint immobilization is accompanied not only by many disorders including rheumatologic disorders, degenerative disorders, trauma and fracture but treatment for disorders. Articular cartilage are sensitive to mechanical events. Immobilization is associated with cartilage degradation that may cause joint pain and reduced range of motion. An understanding of the effects of immobilization on the articular cartilage will help to plan of physical therapy program

In this study, the femur, the tibia, the articular cartilage and the menisci are three dimensionally reconstructed using MR images of healthy knee joint in full extension of 26-year-old male. Three dimensional finite element model of the knee joint is fabricated on the reconstructed model. Also, the FE models of ligaments and tendons are attached on the biologically suitable position of the FE model. Bones, articular cartilages and menisci are considered as homogeneous, isotropic and linear elastic materials, and ligaments and tendons are modeled as truss element and nonlinear elastic springs. The numerical results show the contact pressure and the von Mises stress distribution in the soft tissues such as articular cartilages and menisci which can be regarded as important parameters to estimate the failure of the tissues and the pain of the patients.

골관절염은 연골 파괴 및 연골 형성의 손상을 초래하는 산화 스트레스 세포사와 관련된 염증성 질환이다. 최근에, 엉겅퀴(Cirsium japonicum var. maackii)는 다양한 염증성 질환에 대하여 보호하는 역할을 하는 것으로 보고되었습니다. 그러나, 연골 퇴행 및 골관절염 진행에 대한 엉겅퀴의 역할은 아직 알려져 있지 않았다. 따라서, 본 연구는 골관절염 및 연골 분해 생쥐 모델에서 엉겅퀴의 보호 효과를 조사하였다. 먼저, 엉겅퀴의 활성 성분 함량을 측정하기 위해 총 폴리페놀 함량과 총 플라보노이드 함량 분석을 수행하였다. 그 결과, 건조된 엉겅퀴 지상부의 물 추출물에서 총 폴리페놀 함량은 $149.2{\pm}24.1mg\;GAE/g$ 및 총 플라보노이드 함량은 $27.9{\pm}2.0mg\;NE/g$을 함유하는 것으로 밝혀졌다. 또한, HPLC 분석으로부터 엉겅퀴 지상부 물 추출물의 주요 화합물은 플라보노이드 계열인 cirsimarin과 cirsimaritin으로 확인되었다. 또한, 엉겅퀴 추출물은 조직 병리학적 분석에 의해 입증된 내측 반월판의 불안정화에 의해 유도된 골관절염 마우스 모델에서 연골파괴 억제효과를 나타냈다. 결론적으로, 본 연구결과는 엉겅퀴 추출물이 골관절염과 연골 파괴를 개선 또는 예방할 수 있는 새로운 식 의약 소재로의 개발 가능성을 제시한다.

Purpose : The purpose of this study was to compare the pattern of displaced bucket-handle tear of lateral and medial menisci and the treatment modality and results from accompanying injury. Materials and Methods : Patients who were diagnosed for displaced bucket-handle tear of medial meniscus (group I: 52patients, 52cases) and lateral meniscus (group II: 31patients, 32cases) from September 1998 to December 2002. The mean ages were 25years $(16\~66)$ for Group I and 29years $(18\~63)$ for Group II, and the average follow-up period were 18months $(12\~44)$ and 13months $(6\~46)$, respectively. The zone of meniscus tear and the existence of accompanying injury were verified through intraoperative arthroscopy and discoid type meniscus was additionally examined for group II. The assessment was made according to the physical examination and clinical pattern at the postoperative last follow-up, and the 2nd look arthroscopy was performed in 19cases $(23\%)$ for the cases accompanying anterior cruciate ligament (ACL) injury in both groups. Results : There were 38cases $(73\%)$ in group I, 5cases $(16\%)$ in group II for associating ACL injury. We observed discoid type meniscus (19cases, $59\%$) in group II. At last follow-up clinical success in repair cases of group I and II are 22cases $(85\%)$, 2cases $(67\%)$, in resection cases are 26cases $(100\%)$, 26cases $(93\%)$ respectively. Reoperation is performed 2cases in repair cases of group I. One case is re-rupture, the other case is newly developed tear in white-white zone. Reoperation is performed 2cases due to remnant meniscal tear in resection cases of group II. All of 2cases are discoid type menisci. Conclusion : Displaced bucket-handle tear of medial & lateral menisci would be substantially different an aspect, considering on difference would help to select proper treatment modality.

This case was report of intra-articular bee venom pharmacopuncture injection on the patient with Acute Traumatic Partial tear of meniscus. We used intra-articular bee venom pharmacopuncture injection to Acute Traumatic Partial tear of meniscus diagnosed by symptoms and MR imaging. Be under treatment if necessary we prescribed herbal medication and physiotherapy. The state of patient was measured by Visual Analog Scale(VAS) and Walking time and Western Ontario and McMaster Universities(WOMAC) Index score. After several times of treatments, noticeable reduction of pain was measured and increased time of walking on floor and decreased WOMAC score. This results suggest that intra-articular bee venom pharmacopuncture injection are effective to treatments of Acute Traumatic Partial tear of meniscus.

This study was carried out to investigate the effect of Sorbus commixta (SC), Geranium thunbergii (GT) and their mixture (SC:GT=1:1, MIX) on inhibition of bone loss and chondral defect. To examine their activities, we measured the alkaline phosphatase (ALP) activity in human osteoblast-like MG-63 cells and performed tartrate-resistant acid phosphate (TRAP) staining in osteoclast differentiated from Raw264.7 cells. To investigate the influence on chondrocyte differentiation, we performed alcian-blue staining in chondrocyte differentiated from ATDC5 cells. All of SC, GT and MIX did not increase ALP activity in MG-63 cells. However, SC and mixture (SC:GT=1:1, MIX) significantly inhibited osteoclastic differentiation. And they also induced chondrocyte differentiation. These results suggest that SC and GT may have a potential for the treatment of bone loss and chondral defect by suppression of osteoclast differentiation and stimulation of chondrocyte differentiation. Therefore, clarification of their mechanisms and active components will be needed.

To avoid incomplete coaptation of the peripheral tear of the meniscus an arthroscopic vertical enclosing meniscus suture technique was developed. In this technique the meniscus was not penetrated with any instruments or suture materials. This technique seems to be simple and easy to learn and to practice.
