  • Industry for artificial joint is a complex one based on various technologies, including mechanics, biotechnology, material engineering, and medicine which are connected closely. This industry has been already known to a higher value-added business, and as going into an aging society, is expected a market growth. Also, it is a knowledge based component industry and each components assembled into product is almost all import items. This characteristics made many small and medium and venture enterprises participate in this area. For these reasons, it is needed a government's promotion. In this study, commercialization environment was analyzed and then commercialization items and strategies was figured out. Firstly, three factors for need, environment, technology were analyzed and then growth drivers growth restraints were provided. Secondly, items and strategies for commercialization were analyzed based on needs and trends of technology. Commercialization opportunities are expected to be created based on strategies following as; building a integrated technology development system, making a public opinion, strengthening a marketing, entering into niche market, B2B strategies etc.

Results of Anterior Cruciate Ligament Reconstruction with Unicondylar Arthroplasty for Medial Compartment Knee Osteoarthritis combined with Anterior Instability (전방 불안정성과 동반된 슬관절 내측 구획 진행성 관절염환자에서 전방십자인대 재건술 및 인공 관절 부분 치환술의 결과 - 3예 보고 -)

  • Three cases who had medial compartment osteoarthritis of the knee (Kellgrene-Laurence grade 3 and Outerbridge grade 4) and anterior instability of the knee due to rupture of the anterior cruciate ligament in relative young ages underwent staged anterior cruciate ligament reconstruction followed by medial unicondylar arthroplasty in 2 cases and simultaneous anterior cruciate ligament reconstruction and unicondylar arthroplasty. We evaluated clinical results some kinds of preoperative and postoperative International Knee Documentation Committee (IKDC), Lysholm score and last follow-up hospital for special surgery (HSS), knee society score (KSS). We consider that medial unicondylar arthroplasty with staged or simultaneous anterior cruciate ligament reconstruction is very good option of the treatment for the anterior instability and pain from advanced arthritis.

  • Purpose: Total elbow arthroplasty (TEA) is still in its infancy as compared with other forms of arthroplasty. TEA designs have evolved with experience, but comparatively little long-term outcome data is available. This article provides an overview of the current states of linked, unlinked, and convertible total elbow arthroplasty. Material and Method: The designs of total elbow prostheses can be subdivided into three categories: unlinked, linked, and convertible. This article provides an overview of the current states of linked, unlinked, and convertible total elbow arthroplasty. Results and Conclusion: By proper patient selection and by utilizing implant design advances, improvements in cementation techniques, a meticulous surgical technique, and appropriate postoperative rehabilitation, total elbow arthroplasty can provide a high level of patient satisfaction and pain relief.

  • This paper presents a methodology for constructing a surgical simulation environment for the replacement of artificial knee join using CT image data. We provide a user interface of preoperative planning system for performing complex 3-D spatial manipulation and reasoning tasks. Simple manipulation of joystick and mouse has been proved to be both intuitive and accurate for the fitness and the wear expect of joint. The proposed methodology are useful for future virtual medical system where all the components of visualization, automated model generation, and surgical simulation are integrated.

Do the Rotating Hinge-Flexible Intramedullary Nail Composites Alleviate Junctional Osteolysis in Megaprothesis Reconstruction for Bone Tumor? (탄력성 있는 골수강 내고정물과 회전경첩형 슬관절 전치환물을 조합한 종양인공관절로 자가골의 골 용해를 감소시킬 수 있는가?)

  • Purpose: The authors investigated whether 35 flexible nail-rotating hinge composite reconstructions around knee joint minimize junctional osteolysis of host bone. Material and Method: The reconstructive technique was as follows: 1) en bloc tumor resection, 2) filling of the host bone marrow cavity with multiple Ender nails, 3) assembling the Ender nails and an Endo-Link type total knee component with wire and bone cement. Result: Mean follow-up was 53 months (ranged 30~79). At final follow-up, 29 patients retained a mobile joint. Resection of more than 40% of bone showed a positive relationship with junctional hypertrophy (p=0.028). Eight patients showed nail breakage and eight prostheses were removed due to early or late infection. The cumulative prosthetic survival rate was 33% at 6 year. Average functional score according to the MSTS criteria was 26.8. Conclusion: Mid-term evaluations showed that results were fair. The revision process was straightforward. Junctional hypertrophy observed appears to give some clues as to how to minimize osteolysis at the prosthesis-host junction after modular prosthesis fixation.
