Pseudotumors are not uncommon complications after total hip arthroplasty (THA) and may occur due to differences in bearing surfaces of the head and the liner ranging from soft to hard articulation. The most common causes of pseudotumors are foreign-body reaction, hypersensitivity and wear debris. The spectrum of pseudotumor presentation following THA varies greatly-from completely asymptomatic to clear implant failure. We report a case of pseudo-tumor formation with acetabular cup aseptic loosening after revision ceramic-on-metal hip arthroplasty. The patient described herein underwent pseudotumor excision and re-revision complex arthroplasty using a trabecular metal shell and buttress with ceramic-on-polyethylene THA. Surgeons should be aware of the possibility of a pseudotumor when dealing with revisions to help prevent rapid progression of cup loosening and implant failure, and should intervene early to avoid complex arthroplasty procedures.

Purpose: This study was to evaluate the effect of supportive nursing care program for patients with total hip arthroplasty. Methods: Forty-two patients with total hip arthroplasty were enrolled in this study from September, 20, 2011 to January, 3, 2012. The participants were assigned to one of two groups: Twenty-six subjects in the experimental group were provided with supportive nursing care program which comprised of 6 nurse visits pre and post operation and 4 follow-up phone calls after discharge. Another 26 subjects received conventional nursing care program as a control group. Hip function, anxiety, and uncertainty were evaluated before the intervention, and 5 weeks after completion of the intervention. The analysis included descriptive statistics, Chi-square test, and t-test by SPSS 18.0. Results: Hip function was significantly increased in the experimental group (t=-3.31, p<.002). Anxiety and uncertainty group was significantly lower in the experimental group (t=7.12, p<.001 and t=4.66, p<.001). Conclusion: The results of this study indicate that the supportive care intervention for patients receiving total hip arthroplasty could be utilized as a nursing intervention to improve hip function and to reduce anxiety and uncertainty of patients receiving total hip arthroplasty.

To make a comparative analysis for clinical application of total hip replacement arthroplasty(THRA) using fluoroscopy, we have performed total hip replacement arthroplasty making 30 patients an object with general radiography and fluoroscopy respectively. The results are as follows : 1) Reexamination rate was 80% of patients and mean 3.9 sheets in the general radiography, where as it was 46.7% and 0.37 sheets in the fluoroscopy(p<0.01) 2) Add examination was 2 cases in the general radiography, but fluoroscopy was no add examination. 3) The total film sheet used was mean 10.16 in the general radiography and 6.73 in the fluoroscopy. 4) In the cause of reexmination and add examination, inaccurate position of patient accounted for 72.6% in the general radiography and poor exposure condition accounted for 45.5% in the fluoroscopy. Total hip replacement arthroplasty using the fluoroscopy decreased reexamination and add examination rate, for these reasons, this method was effective abatement of pain, exposured radiation dose, and examination time and so on.

Background: Total hip arthroplasty (THA) is probably one of the most successful surgical interventions performed in medicine. Through the revolution of hip arthroplasty by principles of low friction arthroplasty was introduced by Sir John Charnley in 1960s. Thereafter, new bearing materials, fixation methods, and new designs has been improved. The main concern regarding failure of THA has been the biological response to particulate polyethylene debris generated by conventional metal on polyethylene bearing surfaces leading to osteolysis and aseptic loosening of the prosthesis. To resolve these problems, the materials of the modern THA were developed since then. Methods: A literature search strategy was conducted using various search terms in PUBMED. The highest quality articles that met the inclusion criteria and best answered the topics of focus of this review were selected. Key search terms included 'total hip arthroplasty', 'biomaterials', 'stainless steel', 'cobalt-chromium', 'titanium', 'polyethylene', and 'ceramic'. Results: The initial search retrieved 6921 articles. Thirty-two articles were selected and used in the review. Conclusion: This article introduces biomaterials used in THA and discusses various bearing materials in currentclinical use in THA as well as the newer biomaterials which may even further decrease wear and improve THA survivorship.

Objectives : The purpose of this study was to investigate the effects of using acupuncture and moxibustion for the treatment of hip arthroplasty. Methods : We searched a total of six Korean and international databases (OASIS, KISS, RISS, Pubmed, Cochrane library, and CNKI) up to March 2019, and included randomized controlled trials which investigated the treatment effects of acupuncture and moxibustion in patients with hip arthroplasty. Results : In total, 29 studies were selected and included in the analysis. These studies conducted interventions, with the most frequently conducted methods being electroacupuncture (24.1%) and auricular acupuncture (20.7%). The most frequently used acupoints were the Ashi-, Lower four-, and Lower five points. VAS (48.9%) and Harris scores (22.2%) were commonly used to evaluate treatment effects. In total, 27 studies (93.1%) reported favorable treatment effects following acupuncture and moxibustion treatment, compared to the control group. Conclusions : These results may suggest that acupuncture and moxibustion have favorable effect on Hip arthroplasty.

Objective: This study was conducted to identify predictive factors of physical activity in total hip arthroplasty patients, and to provide basic data for the developing physical activity promotion program for total hip arthroplasty patients. Design: Descriptive correlational research. Methods: Data were collected from August 2017 to May 2018. Surveys were distributed to 60 patients in a G university hospital located at J city, Gyeongsangnam-do. Data were analyzed by frequency, mean, standard deviation, t-test, ANOVA, Pearson's correlation coefficient, multiple regression analysis using SPSS 24 Win program. Results: The variables affecting the 4-week physical activity after discharge were age (β=.07), residence after discharge (β=-.22), cerebrovascular disease (β=-.13), mental and behavioural disease (β=-.11), taking antibiotic (β=-.26), walking ability (β=.41), nutritional status (β=.25), depression (β=.05). The eight variables accounted for 39.4% in the 4-week physical activity (F=4.49 p=.001). The variables affecting the 8-week physical activity after discharge were age (β=.06), waking ability (β=.34), nutritional status (β=.20), exercise self-efficacy (β=.05), depression (β=-.05). The six variables accounted for 28.0% in the 8-week physical activity (F=4.58, p<.001). Conclusions: The walking ability in discharge important to improve the physical activity, there is a need to develop an program to improve walking ability before discharge, in total hip arthroplasty. There is a need to develop a physical activity program to consistently participate in a community.

Purpose: The purpose of this study was to evaluate the effects of real PCA education with practice on postoperative pain, consumption of analgesics, and anxiety for elderly patients with total hip arthroplasty. Methods: This study utilized a non-equivalent control group pretest-posttest design. The participants were 52 elderly patients (${\geq}65$) with total hip arthroplasty at the G. hospital in Seoul. The participants were recruited from December 3, 2014 to April 30, 2015. Twenty six of them were assigned to the experimental group and the other to the control group. Preoperative real PCA education with practice was performed individually with the experimental group by the author. Results: There were statistically significant differences in 24 and 48 hour postoperative pain (t=-2.59, p=.012; t=-3.80, p<.001 respectively), and in consumption of analgesics at 24 and 48 hours after operation between the two groups (t=-3.61, p<.001; t=-4.19, p<.001 respectively). However, no significant difference in anxiety (t=-1.03, p=.308) at 48 hour after operation. Conclusion: This study has confirmed that the individualized real PCA education with practice contributes to relieve postoperative pain and reduce analgesic uses of the elderly with total hip arthroplasty. Thus, it is highly recommended that this education program could be applied in clinical settings as a nursing intervention in reducing postoperative pain for the elderly with total hip arthroplasty.

Dislocation after a total hip arthroplasty occurs in approximately 1% of patients; however, the frequency is much higher after revision surgery. To prevent dislocation, use of a larger femoral head is recommended, and a dual mobility femoral head has been introduced. However, reducing the dual mobility femoral head to the acetabular component is difficult in cases involving contracture in the soft tissue around the joint. A 72-year-old male patient who developed a periprosthetic joint infection underwent two-stage revision surgery using MUTARS^®. Two months after the revision, the hip joint became dislocated and manual reduction was attempted; however, dislocation occurred again. During another revision using a dual mobility bearing, the soft tissue around the hip joint was too tight to reduce. The problem was overcome by first repositioning the dual mobility head into the acetabular socket, followed by assembly of the diaphyseal portion of the implant.

Purpose: The objective of this study was to analyze the results from a cohort of patients who underwent a revision total hip arthroplasty (THA) using a dual mobility cup (DMC) implant. Materials and Methods: A retrospective review of revised THAs was conducted using the database from a single tertiary referral hospital. A total of 91 revision THAs from 91 patients were included in the study. There were 46 male hips and 45 female hips. The mean age was 56.3±14.6 years, and the mean follow-up period was 6.4±5.9 years. In performance of revision THAs, the DMC implants were used in 18 hips (19.8%), and the conventional implants were used in 73 hips (80.2%). Results: During the follow-up period, three dislocations were identified, and the overall dislocation rate was 3.3%. Early dislocation (at one month postoperatively) occurred in one patient, while late dislocation (at a mean of 7.5 years) occurred in two patients. There was no occurrence of dislocation in the DMC group (0%), and three dislocations were detected in the conventional group (4.1%). However, no significant difference in the rate of dislocation was observed between the two groups (P=0.891). Conclusion: Although the rate of dislocation was higher in the conventional group, there were no statistically significant differences between the two groups due to the small number of patients. Nevertheless, we believe that the dual mobility design is advantageous in terms of reducing dislocation rate and can be recommended as an option for a revision THA.
