The incidence of postoperative ileus (POI) after colonic and abdominal surgery is high. On the other hand, the reported incidence after lower extremity reconstruction ranges from 0.3% to 4.0%. This paper reports an 81-year-old woman who expired due to POI at six days after primary total knee arthroplasty. The risk factors, diagnosis, preventive methods, and treatment of POI were also investigated through literature reviews.

Iliac vein compression syndrome, which results in thrombosis of the left iliac veins, was first described by May and Thurner in 1957. May-Thurner syndrome should be considered when deep vein thrombosis-like symptoms appear, especially in the left lower extremities without an invasive procedure. The authors encountered an interesting case of a middle-aged female patient, who presented with sudden pain, swelling and skin color changes to the left lower extremity after right total knee arthroplasty and was diagnosed May-Thurner syndrome by computed tomography venography. This case is of clinical significance in that the early diagnosis of May-Thurner syndrome in the left lower extremity was made, which might have been overlooked after right total knee arthroplasty. This case is reported with a review of the literature review.

Purpose: This study compared the effects of a buprenorphine transdermal patch (BTDP) on the chest and knee for pain control after total knee arthroplasty (TKA). Materials and Methods: A retrospective case-control study was conducted from August 2018 to August 2019 on 231 patients who underwent TKA. Two hundred cases were selected considering age, sex, and body mass index. Before and after applying the BTDP, the Numeric Rating Scale (NRS), adverse effects and compliance were measured. All measurements in the chest application group (group A=100) and knee application group (group B=100) were compared. Results: NRS was similar in rest between the groups treated with BTDP, but at two days and three days afternoon, five, six, and seven days postoperatively in group B, the NRS was significantly lower than that of group A. The adverse effects of the central nervous system and gastrointestinal system after applying BTDP were significantly lower in group B than in group A. No significant differences in adverse effects of the cardiovascular system and skin were observed between the two groups. Regarding the maintenance of BTDP, group B was significantly higher than group A. Conclusion: The direct application of BTDP after TKA to painful knee joints showed excellent results in early postoperative pain control and can be a useful method for increasing patient compliance by reducing the frequency of adverse effects.

Total knee arthroplasty has become a standard procedure for advanced knee arthritis to relieve pain and improve function. Computer-assisted navigation systems have been used in total knee arthroplasty to improve the mechanical axis of the limb as well as the alignment and position of the components. A computer-assisted navigation system has the advantage of real-time feedback during surgery, such as mediolateral balance in extension and flexion gap, alignment of the lower limb, and components. On the other hand, the computer-assisted navigation system requires an additional stab wound for tracker fixation, which can increase the likelihood of superficial wound infection and stress fractures and increase the operation time and cost of surgery. The clinical efficacy of computer-assisted navigation in total knee arthroplasty is also controversial. Compared to the conventional technique, computer navigation improves the accuracy of the postoperative mechanical axis within outliers of $3^{\circ}$ varus or $3^{\circ}$ valgus. This paper reviews the surgical technique, pitfalls, clinical and radiological outcomes, useful clinical cases, and future perspectives in computer-assisted navigation total knee arthroplasty.

Purpose: This study was to identify the factors influencing depression among patients with degenerative arthritis after total knee arthroplasty. Methods: The subjects were 108 patients who admitted or visited K hospital in K city after total knee arthroplasty. Data were analyzed using SPSS WIN 18.0 program. Results: The level of depression was 2.72 with a possible range of 1 to 5. Social support was 3.71 out of a total score 5. Self-efficacy was 64.47 ranged from 10 to 100. Self-esteem was 2.59 ranged from 1 to 5. The associated factors with depression were marital status, length of illness, perceived health status, pain, social support, self-efficacy, and self-esteem. Marital status, length of illness, and perceived health status accounted for 5.8% of depression. Next, all variables including pain, social support, self-efficacy and self-esteem accounted for 66.4% of depression. Conclusion: The level of depression among the subjects significantly be related to marital status, length of illness, perceived health status, pain, social support, self-efficacy and self-esteem. It indicates a need to develop nursing interventions for them to decrease depression and develop quality of life during recovery.

May-Thurner syndrome (MTS), also known as iliac vein compression syndrome, is a condition, in which compression of the common venous outflow tract of the left lower extremity can cause discomfort, swelling, pain or blood clots in the iliofemoral veins. The problem is due to left common iliac vein compression by the overlying right common iliac artery. This paper describes the case of a 75-year-old female with MTS after performing right total knee replacement arthroplasty. The authors diagnosed MTS through intravenous angiography and angiographic computed tomography on swelling and pain of the left lower extremities after performing right total knee replacement arthroplasty. The thrombus was removed using a thrombolytic agent and mechanical thrombectomy, and an intravenous stent then inserted after angioplasty. No case of MTS after performing total knee replacement arthroplasty has been reported in Korea. Therefore, this case is reported along with review of the relevant literature.

Purpose: Tumor infiltration around the knee joint or skip metastasis, repeated infection sequelae after tumor prosthesis implantation, regional recurrence, and mechanical failure of the megaprosthesis might require combined distal femur and proximal tibia replacement (CFTR). Among the aforementioned situations, there are few reports on the indication, complications, and implant survival of CFTR in temporarily arthrodesed patients who had a massive bony defect on either side of the knee joint to control infection. Materials and Methods: Thirty-four CFTR patients were reviewed retrospectively and 13 temporary arthrodesed cases switched to CFTR were extracted. All 13 cases had undergone a massive bony resection on either side of the knee joint and temporary arthrodesis state to control the repeated infection. This paper describes the diagnosis, tumor location, number of operations until CFTR, duration from the index operation to CFTR, survival of CFTR, complications, and Musculoskeletal Tumor Society (MSTS) score. Results: According to Kaplan-Meier plot, the 5- and 10-year survival of CFTR was 69.0%±12.8%, 46.0%±20.7%, respectively. Six (46.2%) of the 13 cases had major complications. Three cases underwent removal of the prosthesis and were converted to arthrodesis due to infection. Two cases underwent partial change of the implant due to loosening and periprosthetic fracture. The remaining case with a deep infection was resolved after extensive debridement. At the final follow-up, the average MSTS score of 10 cases with CFTR was 24.6 (21-27). In contrast, the MSTS score of 3 arthrodesis cases with failed CFTR was 12.3 (12-13). The average range of motion of the 10 CFTR cases was 67° (0°-100°). The mean extension lag of 10 cases was 48° (20°-80°). Conclusion: Although the complication rates is substantial, conversion of an arthrodesed knee to a mobile joint using CFTR in a patient who had a massive bony defect on either side of the knee joint to control infection should be considered. The patient's functional outcome was different from the arthrodesed one. For successful conversion to a mobile joint, thorough the eradication of scar tissue and creating sufficient space for the tumor prosthesis to flex the knee joint up to 60° to 70° without soft tissue tension.
