내측 반월상 연골 후각의 비정상적 부착 - 1례 보고 -
민병현,옥순종,Min Byoung-Hyun,Ok Soon-Jong 대한관절경학회 2001 대한관절경학회지 Vol.5 No.1
내측 반월상연골의 전각부는 경골의 전면에 부착되어 있으며 횡인대에 의하여 외측 반월상연골 전각부와 연결되어 있다. 후각부는 후방 십자 인대 경골부착부 바로 전방에 견고하게 부착되어 있다. 관절경 검사상 반월상연골의 후각부가 경골의 정상적인 부위에 부착되어 종지되지 않고 전각부 하방까지 부착부위가 연장되는 반월상연골이 관찰되어 저자들은 이와같은 비정상적인 내측 반월상연골 1례 를 문헌고찰과 함께 보고하는 바이다. The anterior horn of the medial meniscus is attached to the anterior surface of the tibia. The anterior horns of the medial and lateral menisci are connect with the transverse ligament. The posterior horn of the medial meniscus is firmly attached to the posterior aspect of the tibia just anterior to the insertion of the posterior cruciate ligament. The authors incidentally found an anomalous insertion of posterior horn of medial meniscus into the anterior horn area during arthroscopic examination in the symptomatic knee joint, which had been ruptured anterior cruciate ligament, and report with literature review.

광범위한 반월상 연골 손상에 대한 최근의 치료는 수많은 연구와 임상적 접근을 통해 정상적인 반월상 연골의 기능을 회복하기에 이르렀다. 냉동 보관된 반월상 연골의 동종이식은 연골의 정상적인 회복을 위한 유용한 방법중 하나이다. 저자들의 첫 4례의 동종연골이식은 관절경의 도움으로 시행하였고, 이후 22 예에서는 최소한의 관절 절개를 이용하였다. 또한 모든 동종 연골 이식에서 반월상 연골의 안정성과 회복을 위해 반월상 연골에 골교를 부착하여 고정하였다. 전방 십자 인대 재건술은 반월상 연골 동종이식술시 동시에 시행하였다. 내측 반월상 연골은 일명 Key-hole technique을 사용하여 골터널에 의한 관절 연골의 침습을 최소화하려 하였다. 우선 반월상 연골의 골교를 원통형으로 만들고 수혜자의 슬관절의 전방 십자 인대의 내측연을 따라 골 터널을 만들어 반월상 연골의 골교를 press-fit하도록 한다. 삽입된 반월상 연골은 일반적인 반월상 연골 봉합술로 관절경을 이용하여 봉합한다. 외측 반월상 연골은 내측 반월상 연골과는 달리 반월상 연골의 골교를 반원통 모앙으로 만들고 수혜자의 슬관절의 전방 십자 인대의 외측연을 따라 반원통 모양의 골 요지를 만든다. 반월상 연골을 골 요지에 얻고 인도 봉합사를 경골의 전면으로 뽑아내 이를 묶음으로써 고정을 한다. 삽입된 반월상 연골은 내측 반월상 연골이식술과 같은 방법으로 봉합한다. 저자들은 이와 같은 방법으로 관절 연골의 침습을 최소화하고 비교적 정확한 위치에 반월상 연골을 이식할 수 있었다. The current treatment of extensive meniscal injuries has resulted in numerous investigations and clinical trials to restore normal meniscal functions. A cryopreserved meniscal allograft transplantation is one of the successful methods available to restore the meniscus. All the procedures of 26 cases were performed in an minimal open fashion, though initial four cases were done with the aid of arthroscope. In all of the grafts, we used a bone bridge which was attached to meniscus for better stability and healing. Anterior cruciate ligament reconstructions were also performed simultaneously with the meniscal procedures. We attempted to minimize articular cartilage by employing so called the "Key-hole technique" for the medial meniscus transplantation. First, the meniscal cartilage bone bridge was shaped into a cylinder and a bone tunnel was made just beside the medial border of the anterior criciate ligament insertion of the recipient knee joint, and the bone bridge of the meniscal cartilage was push to press-fit. The inserted meniscal cartilage was sutured by the usually employed technique under arthroscopic control. The lateral meniscus was shaped different to the medial meniscus in that the bone bridge was semicylindrical and the bone trough was made beside the lateral border of the anterior criciate ligament insertion of the recipient knee joint. The meniscus was put into the bone trough and the leading suture was extracted anterior to the tibia and tied the knot. The inserted meniscus was sutured in the same manner as the medial meniscus transplantation. By the above described method, the authors were able to minimize the articular cartilage invasion and transplant the meniscus with relative accuracy.

Recent studies suggest that most meniscal cysts can be treated surgically by arthroscopic management of the meniscal tear and arthroscopic cyst evacuation. But arthroscopic cyst decompression may sacrifice a substantial amount of meniscal tissue that is not torn in order to expose the "stalk" of the cyst. Nowadays, the trend is changing as preserving the involved meniscus to prevent from inevitable degenerative changes after meniscectomy. The purpose of this report is to describe a new surgical technique that minimizes loss of meniscal tissue in hopes of maximizing residual meniscal function. We experienced 10 patients with meniscal cysts that were consisted of four lateral cysts and six medial cysts. Menisci were torn in all cases. Arthroscopic partial meniscectomy and decompression of cysts were performed in 9 cases, and arthroscopic partial meniscectomy and open cystectomy in 1 case. The procedures were consisted of injection of the methylene blue into the cyst, partial meniscectomy of the meniscal tear until the dye was seen in orifice of the cyst, and decompression of cyst through cystic opening. This article serves to confirm the relationship between torn menisci and cysts, to re-evaluate the occurrence ratio of the meniscal cyst on the medial to lateral meniscus, and to assess the efficacy of arthroscopic partial meniscectomy and decompression of cyst as a potentially meniscal sparing procedure.

젊은 성인 Osgood-Schlatter 씨 병의 분류 및 동위 원소 검사의 의의
민병현 ( Byoung Hyun Min ),정남수 ( Nam Su Chung ),김상환 ( Sang Hwan Kim ),조재호 ( Jae Ho Cho ) 대한슬관절학회 2009 대한슬관절학회지 Vol.21 No.4
Purpose: We retrospectively classified the young adult Osgood-Schlatter disease by plain radiography and accessed the relationship between bone scan results and symptom duration. Materials and Methods: From 2004 to 2007, young adults with symptoms of Osgood-Schlatter disease were included in the study. The patients were classified into 3 groups, protrusion, cleft and ossicle, according to their radiographic results. All patients had bone scan exams, we analyzed the correlation between the bone scan results and the duration of symptoms. Results: All patients were male with average age of 19.8 (18.5∼22.0) years old. Out of 59 patients, 27 were bilateral. Of 86 knee joints, 36 came out positive with bone scan. Positive bone scan rate was 11.1% in protrusion type, 40.0% in cleft type and 61.4% in ossicle type. The pain persisted longer in ossicle type than the others. The symptom duration correlated with the bone scan results. Conclusion: We classified young adult Osgood Schlatter disease as three types. The ossicle type of Osgood-Schlatter disease has longer symptom duration, which correlates with the bone scan results. The bone scan result can be one of reliable reference factors for the treatment of young adult Osgood-Schlatter disease.

중간엽 줄기세포의 연골화 분화에 저강도 초음파 자극의 전처리가 미치는 영향
이현정 ( Hyun Jung Lee ),최병현 ( Byung Hyune Choi ),민병현 ( Byoung Hyun Min ),박소라 ( So Ra Park ) 한국조직공학과 재생의학회 2005 조직공학과 재생의학 Vol.2 No.1
To date, the 3-D culture system and TGF-ß? treatment are known as the most critical factors for chondrogenic differentiation of mesenchymal stem cells (MSCs). However, the development of more efficient and versatile methods is still in demand for the clinical application of MSCs in cartilage repair. Recently, low-intensity ultrasound (LIUS) was shown to enhance fracture healing and induce chondrogenesis of MSCs in vitro. We examined the effect of LIUS on the chondrogenic differentiation of rabbit MSCs at the gene expression level. The results showed that the LIUS treatment on a 3-D alginate culture of rMSCs increased 1) the expression of chondrogenic markers such as collagen type II, aggrecan and Sox9 in RT-PCR analysis and 2) the level of collagen type II protein in Western blot analysis. These results suggest that the LIUS treatment facilitate chondrogenic differentiation of MSCs. We speculate that the non-invasive LIUS can be used as a mechanical stimulus to potentiate chondrogenic differentiation of MSCs and hence clinically for the repair of cartilage damage.

노정호,민병현,박정욱,안병문,Roh, Jeong-Ho,Min, Byoung-Hyun,Park, Jeong-Wook,Ahn, Byung-Moon 대한관절경학회 2008 대한관절경학회지 Vol.12 No.1
목적: 전방십자인대 재건술시 흔히 관찰하게 되는 Resident's ridge의 실제 형태학적 위치 및 모양을 알아보고자 한다. 대상 및 방법: 2007년 1월부터 2007년 8월까지 본원에서 시행한 48례의 정상 대퇴골 원위부를 촬영한 MD CT(Multidetector-Row Computed Tomography) 영상을 분석하였다. 과간절흔의 외측벽에서 1 mm 이상의 높이 변화를 보이는 경우를 Resident's ridge로 정의 하였다. $Lucion^{(R)}$ 프로그램을 이용하여 3차원 재구성한 영상을 통해 과간절흔의 전후방 길이, resident's ridge의 길이, 높이, 과간절흔의 후방 피질골로부터의 거리를 측정하였다. 결과: 환자의 평균 연령은 $59{\pm}16$세였으며 남성이 16례, 여성이 32례 이었다. Resident's ridge가 존재 하지 않았던 경우는 9례 이었으며 과간 절흔의 전후방 길이는 $25.4{\pm}3.5$ mm, Resident's ridge 의 길이와 높이의 평균값은 각각 $8.2{\pm}2.6,\;3.5{\pm}1.5$ mm 이었으며 Resident's ridge의 후방 피질골로부터의 거리는 $7.6{\pm}2.6$ mm 이었다. 결론: Resident's ridge는 많은 예에서 존재하며 뚜렷한 길이와 높이가 있기 때문에 전방십자인대 재건술시 주요한 landmark로 사용할 수 있다. Purpose: The purpose of this study was to report the real geometry of Resident's ridge doing in anterior cruciate ligament reconstruction Materials and Methods: From Jan 2007 to Aug 2007, 48 cases which had normal distal femoral condyle analyzed with Multidetector-Row Computed Tomography. Resident's ridge was defined as change of height above 1 mm in lateral wall of intercondylar notch. Anterior-posterior length of intercondylar notch, length and height of Resident's ridge, distance of Resident's ridge from posterior cortex were estimated with 3-D reconstruction using $Lucion^{(R)}$ program. Results: Cases were $59{\pm}16$ years olds and male was 16 cases, female was 32 cases. 9 cases had no Resident's ridge, anterior-posterior length of intercondylar notch was $25.4{\pm}3.5$ mm, average of length and height of the Resident's ridge was $8.2{\pm}2.6,\;3.5{\pm}1.5$ mm. Distance of the Resident's ridge from posterior cortex was $7.6{\pm}2.6$ mm. Conclusion: Resident's ridge was used as landmark in anterior cruciate ligament reconstruction, which presented in many cases and which had distinct length and height.
