Most of discoid menisci are lateral and medial discoid meniscus is very rare. There is no report about simultaneous medial and lateral discoid meniscus in one knee joint. A 15-year-old male patient was diagnosed as having a complete medial discoid meniscus with horizontal tear and intact incomplete lateral discoid meniscus by means of magnetic resonance image and arthroscopy. The patient was treated by arthroscopic partial meniscectomy for both discoid menisci.

Purpose: The purpose of this study was to correlate the degree of sonographic medial meniscal extrusion with MRI and arthroscopic findings. Materials and Methods: Out of these 32 patients, with medial meniscal tear who went on arthroscopic surgery, 14 patients had the medial meniscal tear and 18 patients had both lateral and medial meniscal tear. The extent of meniscal extrusion without meniscal tear was assesed in 24 patients who did not show meniscal tear on MRI. The extent of meniscal extrusion was measured between tibial medial joint line (excluded osteophyte) and the outer margin of the medial meniscus. Kellgren-Lawrence grading scale was assessed in plain X-ray image and the location of lesion was assessed during arthroscopic surgery. We also measured the extent of meniscal extrusion on MRI and sonography respectively, and compared each other. Results: There was significant difference between patients with medial meniscal tear and both lateral and medial meniscal tear, patients with medial meniscal tear, patients with both medial and lateral meniscal tear, patients without meniscal tear (P value<0.05). Conclusion: The Meniscus tear must be considered when sonography shows the meniscal extrusion more than 5 mm in length.

The meniscus is considered "extruded" when it extends beyond the tibial margins more than 3 mm in a coronal view of magnetic resonance imaging (MRI). However, identifying the meniscal extrusion intraoperatively may be difficult because of the simple fact that most of the arthroscopic procedures are done in knee flexion position while follow up MRI studies area taken at knee extension position. Here, we demonstrate the arthroscopic technique for evaluating the meniscal extrusion.

Meniscal extrusion is defined as a distance of 3 mm or more between the peripheral border of the meniscus and the edge of the tibial plateau on the coronal plane, associated with degeneration or tear of meniscus, effusion, osteophyte, osteoarthritis. There are many advantages of ultrasonography, including cost, dynamic real-time assessment. We evaluated a patient with anteromedial mass of the knee by ultrasonography, which was proved to be the extrusion of medial meniscus. We report a case of extrusion of medial meniscus evaluated by ultrasonography with review of the related literatures.

Purpose: This study examined clinical cure and patients' satisfaction degrees by factors influencing surgical operation results, after arthroscopic inside to out repair as a nonabsorbable suture material, in case of meniscal rupture. Materials and Methods: Materials were 110 cases of 95 patients who could make paces for over 12 months from August 1999 to June 2002. Results were evaluated by clinical cure and subjective satisfaction degrees. This study, concerning those results, analyzed age, term from taking pictures to taking surgical operation, rupture section, rupture length, rupture types, lesion of articular-cartilage, and effects of anterior cruciate ligament operation accompanied. Results: 84 cases(76%) were clinically cured, 98 cases(89%) were subjectively satisfied. In case of accompanying anterior cruciate ligament rupture, and in case that rupture length was below 2 cm, rates of clinical cure and patients subjective satisfaction were significantly high. In case of complex or degenerative rupture, patients satisfaction rates were higher when comparing with clinical cure rates. Conclusion: Various sutures are possible as well as available in case of arthroscopic meniscal inside to out repair using nonabsorbable suture material. It can be concluded that patients age is not absolte consideration in determining the suture of meniscus. In cases of complex rupture, degenerative rupture, ruptures companied by joint-cartilage injuries, considerate consideratin need be paid to choose patients and operations.

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.

목적 : 면역억제 작용을 지닌 것으로 알려진 전갈약침(BMK)의 IL-1으로 야기된 1차성 골관절염 인체 연골 세포에 대한 항염증 효과 골 기능 효과에 대해 연구하였다. 방법 : 골관절염 연골에서 채취된 인체 연골세포는 ID-1(2ng/ml)에 의해 처리되어졌으며, IL-1과 BMK($10{\mu}g/ml$)를 함께 처리한 연골세포와 비교하였다. 결과 : IL-1 단독처리된 연골세포에 비해 BMK가 함께 처리된 연골세포에서 연골세포의 손실과 퇴화의 중요한 요소인 NO의 생산량이 의미있게 저하되었다. IL-1단독으로 처리된 연골세포보다 IL-1과 BMK가 함께 처리된 연골세포에서 iNOS mRNA의 단백질 합성이 의미있게 감소하였다. 또한, 전사인자로서의 NF-B의 활성화가 IL-1 단독으로 처리된 연골세포에 비하여 BMK가 함께 처리된 군에서 상대적으로 의미있게 억제되었다. 결론: 이상의 결과를 종합하면 BMK가 인제 골관절염 연골에 있어서 NF-B 활성화에 의존한 IL-1 유도염증의 치료상에 효과적인 반응억제제임을 시사하며, 골 세포의 골 재흡수 활동에 효과적임을 시사한다.

Although the lateral discoid meniscus of the knee has been observed frequently, the discoid medial meniscus has rarely been reported in the literature. A discoid medial meniscus with the horizontal tear and the peripheral tear of upper lip were observed. This tear pattern is not usual in the lateral discoid meniscus as well as in the normal meniscus. A plausible mechanism of the tear pattern compared with the normal shape and the discoid lateral meniscus was discussed in the following.
