Although the lateral discoid meniscus of the knee has been observed frequently, the medial discoid meniscus has very rarely been reported in the literature. A 22-year-old female patient was diagnosed as having a medial discoid meniscus with horizontal tear by means of magnetic resonance image and arthroscopy. The patient was treated by arthroscopic partial meniscectomy.

목적 : 본 연구는 화피의 연골 보호 및 소염 진통 작용을 알아보고, 화피를 이용한 관절염치료 약침액 개발의 기초자료를 얻기 위해 고안되었다. 방법 : In vitro에서는 토끼 무릎관절에서 배양된 연골조직에 5ng/ml IL-1${\alpha}$ 처리 후， 화피의 연골보호 효과, 연골세포에 대한 독성을 조사하였다. In vivo에서는 토끼 무릎관절내 collagenase를 주입, CIA 유발 후, 28일간 매일 토끼의 구강으로 화피, 증류수, CEX를 투여하였으며, 연골보호, 소염, 진통에 대한 측정을 하였다. 결과 : 화피는 proteoglican 및 collagen분해 억제, MMPs 활성 억제로 연골 보호 효과가 있었으며, 연골 세포에 대한 독성이 없었다. 소염작용은 PGE2 생산 억제 및 COX-2발현 억제, carrageenan 유발 쥐 모델에서의 부종 억제로 확인되었다. 진통작용은 tail flick test에서의 latency time 증가, formalin test에서의 염증성 통증억제로 나타났다. 결론 : 화피가 퇴행성관절염에 대한 연골 보호 효과 및 소염 진통 작용이 있으므로, 이를 근거로 약침액을 개발 응용하면 퇴행성관절염 치료에 활용될 수 있다고 사료된다.

Root tear of the posterior horn of the medial meniscus can occur from trauma or chronic degeneration, leading to meniscus extrusion, articular cartilage loss, osteophyte formation, and medial joint space narrowing. It is common on middle age with or without minor trauma. We experienced a case of medial meniscus posterior horn root tear in 13 years old boy during baseball game. We performed 1 direct suture anchor repair for medial meniscus posterior horn root tear in adolescent and report clinical result.

Several methods to resurface the lost cartilage of the knee have been used; multiple drilling, microfracture, abrasion arthroplasty. Resurfaced cartilages resulting from above techniques are mostly fibrocartilage. Autologous osteochondral graft transfer and autologous chondrocyte transfer are known to resurface the lost cartilage with mostly hyaline cartilage. This article reviews basic researches, indications, operative technique, and clinical results of autologous osteochondral graft transfer.

Synovial chondroma is an uncommon benign lesion characterized by metaplastic cartilage formation within the synovial connective tissue, usually intraarticular, commonly affects the knee, hip and elbow. We would like to present the case of a 65-year-old man suffering from synovial chondroma of the right elbow responsible for radial nerve entrapment neuropathy. This is a case of synovial chondroma of the right elbow in an 65-year-old man presenting with pain and restricted joint movement of the right elbow, loss of extension and sensation of the right thumb and wrist. Plain radiographs showed narrowing of elbow joint space, bony spur on the edge of the joint, and radio-opaque sclerotic change of subchondral area. MRI revealed $16{\times}12$ mm sized round mass on the radial head, homogenous low signal on T1WI, heterogenous high and low signal on T2WI. The patient underwent marginal excision of the mass, compressing the radial nerve. Diagnosis was confirmed by histologic examination.

Purpose : The purpose of this prospective study was to evaluate second look arthroscopic finding after osteochondral autograft transfer(OAT) for the treatment of the chondral defect of the knee. Materials & Methods : Fourteen out of forty cases underwent second look arthroscopy after the OAT for the treatment of the chondral defect of the knee. The average age of patients was 34 years. Preoperatively, magnetic resonance imaging was performed in eleven cases and chondral defect was confirmed in nine cases. The site of the chondral defect located at medial femoral condyle at seven, trochlea in four, and lateral fomoral condyle in three cases. The average size of the condral defect was $13\times10mm$, maximum $22\times20mm$. The number of graft was one in eight, two in three, three in two, and five in one case. The average follow-up period was twenty-one months. Second look arthroscopy was performed at six months in almost cases. Results : After the OAT, $86\%$ of cases showed that the consistency of grafted cartilage was firm and $93\%$ of cases showed that grafted cartilage was well incorporated with surrounding cartilage. Conclusion : The results of this study suggest that OAT can be one of treatment modality in the chondral defect of the knee.

Meniscal allograft transplantation is considered to restore important functions of the meniscus after total and subtotal meniscectomy. There are patients who need meniscal allograft transplantation have concomitant lesions; chronic anterior cruciate ligament tear, chondral defect, and malalignment of the knee. Therefore proper selection of the patients and thorough preparation of operative procedure are imperative to get satisfactory results.

Purpose: To identify the damage of the articular cartilage and analyze the clinical results of the partial medial meniscectomy. Materials and Methods: From January 2001 to December 2004, forty-eight patients in the degenerative arthritis and medial meniscal tear of knee who undertook arthroscopic partial meniscectomy and were able to keep pace with the times follow-up for more than 3 years were enrolled in this study. Six cases were men and 42 were women, and the mean age was 55.7 years (40~78 years). The patients were classified into two groups according to the Outerbridge grade. Grade I and II were classified into group 1 and grade III and IV into group 2. Group 1 included 30 cases and group 2 included 18 cases. The result were analyzed according to the Tapper & Hoover classification and Lysholm knee scoring scale. And we measured the distance of medial joint space in standing anteroposterior (AP) view of both sides at the pre-operative and the last follow-up. Results: According to the Tapper & Hoover classification, 28 cases were excellent, 7 cases good, 8 cases fair, and 5 cases poor. Among group 1, 25 cases were excellent, 2 cases good, 2 cases fair, 1 case poor. However, among group 2, 3 cases were excellent, 5 cases good, 6 cases fair, 4 cases poor. Average Lysholm knee score was improved from 62.4 preoperatively to 94 postoperatively in group 1, and from 58 preoperatively to 77.9 postoperatively in group 2. The joint space narrowing showed no statistically significant difference in both knees standing AP view. Conclusion: The arthroscopic partial meniscectomy for a patient with the degenerative articular cartilage was an effective treatment. However, we could not satisfy the results, in cases of Outerbridge grade III and IV. In grade III and IV, the partial meniscectomy was not aggravated the cartilage damage.

Although the lateral discoid meniscus has been observed frequently, the medial discoid meniscus is an extremely rare anomaly. The incidence of lateral discoid menisci ranges from 1.4% to 15.5% and the incidence of medial discoid menisci ranges from 0.06% to 0.3%. We present 1 patient of bilateral medial discoid menisci with tear on left side and 1 patient of unilateral medial discoid meniscus with tear, that were diagnosed by magnetic resonance imaging (MRI) and arthroscopy. We performed partial meniscectomy on 2 cases of symptomatic medial discoid menisci under arthroscopy and meniscus-related symptoms were relieved. We report 3 cases of 2 patients with medial discoid meniscus.

목적 : 만성 염증성 질환에 대한 전침효과를 알아보기 위해 complete Freund's adjuvant(CFA) 유발 관절염 모델의 거퇴 관절 내 염증관련 단백질 및 복합당질의 변화를 살펴보았다. 방법 : Sprague-Dawley계 흰쥐의 족부에 CFA를 주사한 다음 3일 간격으로 2Hz, 15Hz 및 120Hz 전침자극을 주며 부종 형성여부를 plethysmometer로 측정하여 판정하였으며 30일째 거퇴관절을 취하여 4% paraformaldehyde에 고정하고 EDTA용액에서 탈회시켜 파라핀연속 절편을 얻어 $NF-{\kappa}B$를 비롯한 5종의 염증관련 단백질의 발현 및 복합당질 변화를 살펴보았다. 결과 : 관절연골 내 면역반응 중 연골기질은 반응이 없거나 약하고 연골세포는 $NF-{\kappa}Bp65$, $I-{\kappa}B{\alpha}$, iNOS 반응이 강하며 특히 유리연골층에서 더 현저하였으나 염증 및 전침자극에 따른 변화는 없었다. 관절낭에서 면역반응을 살펴보면 염증유발시 활액세포의 면역반응세포는 $I-{\kappa}B{\alpha}$가 감소한 반면 iNOS, $IL-1{\beta}$는 증가하며 특히 iNOS 증가가 현저하였으며 전침자극에 의해 iNOS 가 감소하였다. 활액막조직에서 모든 면역반응이 증가하며 특히 $NF-{\kappa}Bp65$, $I-{\kappa}B{\alpha}$, iNOS 반응이 현저한데 전침자극에 의해 $IL-1{\beta}$를 제외한 모든 반응이 감소하였다. 복합당질 염색성은 CFA를 주사한 염증유발 흰쥐군이 정상군에 비해 감소하였다. 관절연골 중 구역간질의 중성복합당질 및 연골세포피막의 산성복합당질이 현저히 감소하였다 Lectin반응도 DBA을 제외한 모든 발현이 염증유발시 감소하였다. 그러나 전침처리에 의해 정상군과 유사한 염색성과 lectin반응을 유지하였다. 특히 구역간질의 중성복합당질과 연골세포의 sWGA와 RCA-1 반응이 현저하였다. 결론 : 만성 염증성 동물모델의 거퇴 관절 내 염증관련 단백질은 관절연골보다 관절낭에서, 복합당질의 변화는 관절연골에서 큰 변화를 보였으며 전침의 자극에 의해 이들 변화가 억제되는 것을 알 수 있다. 이상의 결과로 보아 전침처치는 염증관련 단백질 발현 및 복합당질의 변화 억제를 통해 만성 관절염 질환에 효과적임을 알 수 있다.
