Purpose: To evaluate the histologic effect(LM and EM findings)of nonablative LASER and thermal energy on knee joint capsule of rabbit. Material and Methods: The nonablative LASER and thermal energy was applied to the rabits(average age 36 weeks, weight 5 ㎏). There were divided into 4 groups with 6 rabbits in each. The group I received 6 watts of LASER, group Ⅱ 12 watts of LASER, group Ⅲ 60° of thermal energy, and group Ⅳ 70° of thermal energy. The histologic study included H-E, Massons trichrome stain and electron microscopy at immediate, 3 weeks and 6 weeks after operation. Results: The histologic finding in immediate after operation was shown a fibrous degeneration of collagen on all groups and related to the energy level. The histologic finding after 3 weeks showed fibrosis and this fibrosis related the level of energy. Especially the group IV was shown flattening of capsule and deep fibrosis. The histologic finding after 6 weeks was shown marked recovery of collagen arrangement and capillary proliferation in group Ⅰ,Ⅱ and Ⅲ. But in the group Ⅳ not recovered. Conclusion: The nonablative LASER or thermal energy can cause degeneration, fibrosis and contracture of joint capsular collagen.

Arthroscopic anterior cruciate ligament reconstructions using bone-patella tendon-bone have been considered the best method by which others are compared. The notchyplasty is one of the important steps of this procedure and it is emphasized recently to prevent retear of the reconstructed ACL caused by impingement. However, until now, there is controversy about adequate amount of notchyplasty. Also, it is hard to examine the adequacy of notchyplasty even in the arthroscopic field, The purpose of this paper is to describe the surgical technique of notchyplasty, using the flexible reamer and preliminary result of its operation. In this study the results of ACL reconstruction with notchyplasty which is made by us were analized from January. 1994 to December, 1995. The results were as follows: 1. The notchyplasty with flexible reamer is the method that can be obtained adequate amount of removal, perfectly smooth notchyplasty. 2. The range of motion of the affected knee joint was normal ROM after post operation 6 month. 3. In the last follow up, 2 cases were positive in anterior drawer test 4 cases were positive in Lachmann's test and 1 knee was positive in Pivot shift test 4. Average Lysholm knee scoring scale was 70 points at preoperative and 92 points at the last follow up.

슬관절의 내측 원판형 연골의 빈도는 상대적으로 드문데, 저자들은 최근 내측 원판형 연골로 진단된 환자를 치료한 경험이 있어 이를 보고하고자 한다. 남자 20세로서 특별한 외상력 없이 수년간의 슬관절 동통을 주소로 내원하여 자기공명영상 검사상 내측 원판형 연골로 잠정 진단되었다. 관절경 검사상 완전형으로 확인되었으며 수평파열이 동반되어 있었다. 이에 관절경하 연골판 부분절제술을 시행하였으며, 술후 증상의 완전한 소실을 보였다.

연부조직에 발생되는 골육종은 매우 드문 종양으로, 세계적으로 소수의 예가 보고되었으며 한국에서는 2례가 보고되었을 뿐이다. 문헌상 세계에서 최고령의 증례인 91 세 남자에서 외상, 방사선 조사, 화골성 근염, 피부 근염 등과 관련없이 슬관절 주위에 발생한 연부조직 골육종을 경험하였다. 절제술만으로 치료하였으며, 환자는 수술 후 1년 추시 상 생존해 있고 국소재발이나 전이의 징후가 없으며 슬관절의 기능도 양호한 상태이다.

저자들은 좌측 슬관절 슬와부 종창으로 내원한 56세 남성 환자에 대해 자기공명영상 검사를 시행하여 슬와 낭종과 슬와 낭종 내부의 비석회화성 유리체를 확인하였다. 절개 생검술을 통한 조직 검사를 통해 비석회화성 유리체를 활액막성 연골종증으로 진단하였기에 슬관절의 관절 외 활액막성 연골종증에 대한 문헌 고찰과 함께 보고하는 바이다.

슬관절 전치환술 후 감염은 큰 관심을 가지는 문제로 국소 부위 및 전신적 감염의 형태로 나타날 수 있으며, 때로는 패혈증으로 진행되는 사례가 보고되고 있다. 이러한 패혈증은 신체의 다양한 부위로 전파될 수 있으며 사망에까지 이르게 하는 중대한 합병증이다. 하지만 감염 후 척추로 전이된 경우는 임상 증상이 뚜렷하지 않아 진단이 어려우며, 이러한 증례에 대한 보고는 어떠한 문헌에도 없었다. 이에 양측 슬관절 전치환술 후 감염으로 인하여 패혈증으로 진행되어 척추로 전이된 증례를 보고하고자 한다.

동시에 발생되는 전방십자인대와 슬개건의 급성 파열은 매우 드물게 발생되며, 손상후 초기의 검사에서 간혹 슬개건 파열을 진단하지 못하는 경우가 있다. 저자들은 우측 슬관절에 전방십자인대와 슬개건의 동시에 발생되는 급성 파열로 전방십자인대는 동종 아킬레스건을 이용하여서 재건술을 시행하고, 슬개건에 대해서는 직접 봉합술 및 동종아킬레스건을 이용한 보강술을 시행하여 슬관절 운동의 강직이나 불안정성 없이, Lysholm 점수는 93점, Tegner Activity Score는 6점으로 좋은 결과를 보였기에 증례 보고를 하고자 한다.

Purpose: The diabetic foot lesions are intractable, and aggravation often leads to amputation. None or minor amputation group was treated debridement or toe amputation and major amputation group was treated Ray, Lisfranc, Chopart, Below Knee and Above Knee amputation. We investigate the risk factors for major limb amputations among patients with diabetic foot lesion. Materials and Methods: The subjects were 73 diabetic foot lesion patients (83 diabetic foot lesions) treated at our department from January 2006 to December 2010. Non or Minor amputation group of 44 cases were treated with debridement or toe amputation. Major amputation group of 39 cases were treated with Ray, Lisfranc, Chopart, below or above Knee amputation. We investigated socioeconomic factors, diabetes mellitus related factors and wound related factors and laboratory factors. Statistical analysis was done by Students t-test, Chi-square test, Mann-Whitney's U test. Results: In our analysis, wound size, wound classification (Wagner classification, Brodsky classification), white blood cell counts, polymorphoneuclear neutrophil percentage, hemoglobin, C-reactive protein and albumin were risk factors for major amputation (p<0.05). Conclusion: Low education level, nutritional condition, premorbid activity level and progressed wound condition were observed in major amputation group compared with non or minor amputation group. In the major amputation group, higher white blood cell count, C-reactive protein level and lower albumin level were observed. Together with maintenance of adequate nutritional condition, early detection of lesions and foot care for early treatment is important. Therefore, active investigation with full risk evaluation of vascular complication is also important.

Background: The purpose of this study was to evaluate the usefulness of sonication technique for microbiological diagnosis and the sterility of the recycled autoclaved femoral components from infected total knee arthroplasty (TKA) using a sonication method. Methods: Nineteen femoral implants explanted from patients with infected TKA were sterilized with a standard autoclave method. Standard culture of the fluid before and after sonication of the sterilized implants was performed to detect pathogenic microorganisms. Additional experiments were performed to evaluate the sterility of the recycled implant by inducing artificial biofilm formation. Methicillin-resistant Staphylococcus aureus (MRSA) was inoculated into 10 implants and sterilization in a standard autoclave was performed, and then the fluid was cultured before and after sonication. Results: Two of the 19 sterilized implants were positive for growth of bacteria after sonication, whereas no growth was detected in the cultured fluid from the sterilized implants before sonication. The bacteria were Staphylococcus species in all two cases. In one of 10 implants inoculated with MRSA, the culture was positive for growth of bacteria both before and after sonication. However, Staphylococcus epidermidis was cultured from both occasions and thus this implant was thought to be contaminated. Conclusions: We found sonication for identification of pathogens could be helpful, but this finding should be interpreted carefully because of the possibility of contamination. Sterilization of an infected femoral implant with an autoclave method could be a good method for using the temporary articulating antibiotic spacer in two-stage revision arthroplasty.
