Purpose: We evaluated the complications and failures after total ankle arthroplasty during at least 2 years short term follow up. Materials and Methods: There were 45 cases of 42 patients of HINTEGRA$^{{R}}$ (Newdeal SA, Lyon, France) model from November 2004 to August 2006. Follow up averaged at least 2 year. We evaluated the complications and analyzed the cause of the failures. Results: There were totally 15 cases of complication, 5 cases of medial impingement syndrome, 3 cases of varus malposition, 2 cases of delayed healing of wounds, and each one case of deep peroneal nerve problem, medial malleolus fracture, post-operative deep infection, gouty arthritis pain, and Achilles tendinitis. Conclusion: Total ankle arthroplasty had higher complication rate than any other joint arthroplasty, so we need a more meticulous preoperative and peri-operative care.

Although total ankle arthroplasty (TAA) has increased considerably in the past ten years, reflecting improvements in implant design and survivorship, the clinical outcomes have been less satisfactory than total hip or total knee arthroplasties. Several issues under debate include postoperative management and rehabilitation in TAA. Especially, there is no consensus or evidence for the most appropriate postoperative management and rehabilitation for patients undergoing TAA. This study was therefore undertaken to suggest appropriate postoperative management and rehabilitation in TAA, after reviewing published articles and focusing on the following topics: prehabilitation, hospital stay, immobilization type and duration, weight-bearing management, pharmacological treatment, and adopted rehabilitation protocols. In previous studies, the postoperative management and rehabilitation proposed depended on the surgeon's preference, the patient's characteristics, and the associated surgical procedures performed after TAA. Nonetheless, our research indicates the best approach is to include a prehabilitation program, immobilization in the early postoperative stage (2~4 weeks), range of motion exercise with partial weight-bearing ambulation, followed by full weight-bearing ambulation after six weeks. Further studies are required to develop a standardized rehabilitation protocol and improve the overall quality of care after TAA.

목적: 종양인공관절 주위 골절은 안정된 고정의 어려움과 골유합 후에도 골질 약화로 해리 및 재골절 위험이 많다. 피질골 지주 중첩 동종골 이식술을 종양인공관절 주위 골절에 적용하면 내고정도 쉽고, 골유합 기간도 단축되며, 합병증도 줄일 수 있을 것이라고 생각하였다. 본 연구는 종양인공관절 주위 골절 27예(30 골절)의 골절의 양상과 치료 후 재건 술식에 따른 생존율 및 합병증, 중첩 동종골 이식술 추가 여부에 따라 골유합 기간 및 기능적 결과가 차이가 있는지 분석하였다. 대상 및 방법: 골절 치료 시 판형 동종골 이식을 한 군 16예와 시행하지 않은 군 14예를 비교하였다. 분석항목은 종양인공관절 치환술부터 골절까지 기간, 골절의 양상, 골유합 기간 차이, 합병증, 및 기능적 결과를 기술하였다. 결과: 골절 양상은 unified classification system (UCS) B형이 21예(70.0%, 21/30)로 가장 많았으며 그 중 B1이 14예(46.7%, 14/30), B2가 1예(3.4%, 1/30), B3가 6예(20.0%, 6/30)였고 C형이 9예(30.0%, 9/30)였다. Kaplan-Meier 법에 의한 30 재건 부위의 5년, 10년 생존율은 각각 84.5%±4.18%, 42.2%±7.83%였다. 전체 30예의 골유합 기간은 평균 5.1개월(범위, 2.0-11.2개월)이었다. 동종골 이식군은 평균 3.5개월(범위, 2.0-6.26개월)로 고식적 고정군의 평균 7.2개월(범위, 4.0-11.2개월)보다 짧았다(p<0.0001). 최종 기능평가상 동종골 이식군은 평균 26.1점으로 고식적 고정군의 평균 20.9점보다 높았다(p<0.0001). 합병증은 4예로 모두 동종골을 사용하지 않은 군에서 있었다. 결론: 종양인공관절 주위 골절은 드물고 골유합도 비교적 잘 이루어지나 유합 후 합병증 최소화가 중요하다. 판형 중첩 동종골 이식술은 골유합 기간을 단축, 골질 증가, 해리위험성 감소 효과가 있으며 종양인공관절 주위 골절에 유용한 방법이다.

In treatment of failure in ankle joint replacement therapy, talar avascular necrosis with massive bone defect, talus fracture with severe comminution and bone defect and ankle dislocation, treatment of large bone defects is considerably important for ankle joint stability and union, therefore, the choice of treatment for large bone defects is use of femoral head or iliac crest bone graft and rigid internal fixation. Because first generation total ankle arthroplasty performed for the first time using a cemented fixation technique requires a large amount of bone resection during re-surgery and there is some possibility of a larger bone defect after removal of implants, in cases where prosthesis for the defect is needed, performance of palliative femoral head or iliac crest bone graft and rigid internal fixation can be difficult. We report on a case of a 48-year-old woman who had experienced ankle pain for 25 years since undergoing total ankle arthroplasty. Because the patient had little ankle motion and rigid soft tissue despite a large bone defect caused by aseptic loosening, a good outcome was obtained only for the femoral cancellous bone graft using allo femoral head without internal fixation.

In orthopedics, hip arthroplasty is the operation that replaces damaged hip joint to artificial joint. In hip arthroplasty, quite better result can be achieved if robot is applied to machine cavity in bone, especially when cementless stem is used. So several kinds of robots were introduced for hip arthroplasty, but they used MRI, CT Scan, vision analysis and real time tracking of bone position for registration of robot. To overcome shortage of conventional robot surgery, gauge based registration method was proposed and small robot was designed. In this method, small robot is mounted on femur, and its position is determined by gauge registration method. Operation procedure was performed on model femur and result was analyzed. This robotic hip surgery system is expected to more adaptable in operation room.

Purpose: The purpose of this research was to identify factors that influence health-related quality of life of patients who have had knee or hip arthroplasty. Factors included sleep disorders, pain, activities of daily living, and depression. Methods: The participants in this research were 97 patients within one year after receiving knee or hip arthroplasty surgery and who regularly visited a hospital outpatient department. Data were analyzed using descriptive statistics, t-test, ANOVA, and stepwise regression analysis with the SPSS program. Results: Sleep disorders, pain, activities of daily living, and depression had significant correlations with health related quality of life. Factors influencing health-related quality of life among arthroplasty patients were the length of time since surgery, sleep disorders, activities of daily living, and depression. These factors explained 58% of the participants' health-related quality of life. Conclusion: The results show that various factors can affect patients' health-related quality of life following joint replacement surgery. The findings indicate that sleep disorders and depression should receive continued attention after the arthroplasty. It is also necessary to develop appropriate nursing intervention programs to lower depression and increase patient participation in daily living activities.

Ceramic femoral heads are now widely used in Total Hip Replacement (THR). Due to their high biocompatibility and low ductility, ceramic femoral heads are considered to be suitable for young and active patients. However, as in testing the mechanical stability of the femoral head, the conventional proof test (standard ISO 7206-10) has its limit of showing axisymmetric stress distribution on the contact surface, while non-uniformed stress distribution is expected after THR. Since non-uniformed stress distribution can result in the increased probability of ceramic femoral head fracture, it is considerable to evaluate the stress distribution in vivo-like conditions. Therefore, this study simulated the ceramic femoral heads under in vivo-like conditions using finite element method. The maximum stress decreased when increasing the size of the femoral head and stress distribution was concentrated on superior contact surface of the taper region.

Purpose: The purpose of this study is to examine how well patients who had hip arthroplasty comply with medical regimens given to them after the operation. Method: The subjects of the study were patients who had arthroplasty at P Hospital between April 1, 2001 and August 30, 2002. 20 patients of the subjects experienced complications after the operation and the other 20 did not. Data from a survey using the qustionnaire were statistically analyzed in terms of real number, percentage point, mean and standard deviation by using $X^2$-test, t-test and ANOVA. Result: 1) the surveyed patients were significantly different in the compliance of medical regimen among them according to their education background as one of the subjects general characteristics. 2) It was found that the group of complication was higher in the compliance of medical regimen than that of non-complication. The two groups showed statistically significant difference with each other in the degree of compliance with therapeutic instructions than the experimental group in terms of the maintenance of abduction after the operation, training instructions on step-by-step basis, urination cotrol on bed, accurate use of crutch, compliance with medication, balance among medical treatment, training, leisure, rest and nutrition, instructions by physicians, nurses and physical therapists, use of low armchairs and toilet bowels and no bending of the body forward, and use of a non-operated leg in case of go upstairs or downstairs. Conclusion: It seems necessary to develop systematic and sessional education programs for improving the compliance of medical regimen, ultimately reducing complications following hip arthroplasty.

Purpose: We report the clinical and radiographic result of ligament reconstruction using plantaris and total ankle replacement in end-stage ankle arthritis with ankle instability. Materials and Methods: The study is based on the 9 cases among total 48 patients of end-stage ankle arthritis that were treated with total ankle prosthesis and ligament reconstruction from 2007 to 2009 at least 12 months follow-up. We evaluated the VAS (Visual analogue scale) pain score, AOFAS (American orthopedic foot and ankle society) score and radiographic measurements. Results: Average age was 59.4 years (53~67 years) old. VAS pain score improved from preoperative average $8.2{\pm}0.9$ (range, 7~10) to $2.7{\pm}1.7$ (range, 0~6) and the AOFAS score improved from $46.4{\pm}14.6$ points (range, 23~69) to $80.1{\pm}9.3$ points (range, 65~95) at final follow-up. Anterior draw test improved $15.2{\pm}3.4$ mm (range, 12~23 mm) to $8.8{\pm}2.6$ mm (range, 6~13mm), varus stress test improved from $13.9{\pm}4.6^{\circ}$ (range, $10-18^{\circ}$) to $6.2{\pm}4.7^{\circ}$ (range, $2-18^{\circ}$) at final follow up. Conclusion: Plantaris ligament reconstruction is good option as part of the management of ankle instability with end-stage ankle arthritis. We achieved good clinical and radiographic results.
