Lifestyle and health-related quality of life in Asian patients with total hip arthroplasties

Psychometric properties of Japanese version15D and cultural characteristics of quality of life undergoing patients with hip and knee arthroplasty

BACKGROUND

Health-related quality of life (HRQoL) following total hip and knee arthroplasty (THA/TKA) may decline more in Asian countries due to lifestyle and housing factors compared with patients in Western countries.

AIMS

To evaluate the psychometric properties of the Japanese version of 15D and clarify the characteristics of HRQoL in Japanese patients who underwent THA/TKA compared with Finnish patients.

METHODS

This longitudinal study included 182 patients between 2019 and 2021. Patients' HRQoL was measured using the 15D preoperatively and 3 months postoperatively. Student's t-tests were used to compare lifestyles between Japan and Finland.

RESULTS

The Japanese version of the 15D showed good internal consistency, reliability, construct validity, and responsiveness. Patients with many steps inside their house had worse HRQoL in the dimensions of mobility, distress, and vitality in Japan. There were significant differences in mobility, distress, vitality, and sexual activity dimensions between Japan and Finland 3 months postoperatively.

CONCLUSIONS

The lower HRQoL in Japan in the dimensions of mobility, distress, and vitality is likely due to Japan's traditional housing structure with many steps. Identifying differences in cultural and psychological characteristics, as well as by residential setting, will enable health care providers to help patients improve their HRQoL.

Discharge Planning and Challenges for Patients With Asian Lifestyles Following Total Hip Arthroplasty: National Survey Design in Japan

This study examined discharge planning and challenges for patients following total hip arthroplasty in Japan. A cross-sectional national survey of 500 hospitals was conducted in May 2019. Discharge planning education tended to include content on dislocation prevention, including prevention while using a squat toilet and crouching down to sit on the floor or sleep on a futon on the floor-activities common in many Asian communities that require a maximum flexion of the hip joint. The challenges of discharge planning included diverse lifestyles, aging issues, lack of assistance at home, lack of consensus on dislocation prevention intervention, limitation of standardized care, interprofessional collaboration, and lack of time to educate family. Tailored discharge planning can be challenging, particularly for aged patients who practice "floor culture", i.e., sleeping, sitting and eating on the floor. Discharge planning needs to be task shifted from the surgeon to the nurse to enhance nurses' empowerment in Japan.

Biomaterial Integration in the Joint: Pathological Considerations, Immunomodulation, and the Extracellular Matrix

Defects of articular joints are becoming an increasing societal burden due to a persistent increase in obesity and aging. For some patients suffering from cartilage erosion, joint replacement is the final option to regain proper motion and limit pain. Extensive research has been undertaken to identify novel strategies enabling earlier intervention to promote regeneration and cartilage healing. With the introduction of decellularized extracellular matrix (dECM), researchers have tapped into the potential for increased tissue regeneration by designing biomaterials with inherent biochemical and immunomodulatory signals. Compared to conventional and synthetic materials, dECM-based materials invoke a reduced foreign body response. It is therefore highly beneficial to understand the interplay of how these native tissue-based materials initiate a favorable remodeling process by the immune system. Yet, such an understanding also demands increasing considerations of the pathological environment and remodeling processes, especially for materials designed for early disease intervention. This knowledge would avoid rejection and help predict complications in conditions with inflammatory components such as arthritides. This review outlines general issues facing biomaterial integration and emphasizes the importance of tissue-derived macromolecular components in regulating essential homeostatic, immunological, and pathological processes to increase biomaterial integration for patients suffering from joint degenerative diseases.

Marital Relationship and Quality of Life in Couples Following Hip Replacement Surgery

For the majority of patients with osteoarthritis, total hip (THA) arthroplasty results in a significant reduction in pain, emotional distress, and disability and a significant improvement in their quality of life. Little is known about how these recovery-related changes impact the spouse or the marital relationship. Methods: Twenty-nine couples whose spouse underwent a THA (29 THA) participated in a semi-structured retrospective interview designed for this study. They were each asked to recall the level of pain before and after surgery and to provide a numerical rating score for questions pertaining to the level of disability in seven different activities of daily living. Couples were also asked to list in order of importance the five ways in which the surgery affected their overall quality of life. Results: The spouses estimated their partner’s pain, both pre- and postoperatively, to be significantly higher level than the patient’s perception. The spouses perceived a greater improvement in family/home responsibilities, recreation and social activities, and in their occupation than that noted by the partner. After the arthroplasty, the spouses indicated that their lives had improved with respect to doing more activities/leisure (72%), because their partner had less suffering (59%), they had more independence/less caregiving (55%), it improved their marital relationship (52%), they had a better social/family life (28%), and they were able to travel (28%). Conclusions: This study indicates that THA result in a significant improvement in quality of life not only for the patients, but also for their spouses.

Understanding key home and community environment challenges encountered by older adults undergoing total knee or hip arthroplasty

BACKGROUND AND OBJECTIVES

Older adults undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) experience significant challenges while navigating their homes post-surgery and are at higher risk for falls and injuries. This study explored specific home and community physical environment challenges faced by community-dwelling older adults while performing daily activities and actions taken to modify their homes before surgery.

RESEARCH DESIGN AND METHODS

Using a qualitative descriptive methodology, semi-structured interviews were conducted with 22 older adult-care partner dyads pre- and post-surgery to identify key built environment barriers and facilitators in addition to home modifications made pre-and post-surgery.

RESULTS

Challenges anticipated by participants to perform daily activities pre-surgery varied from those experienced post-surgery. Lack of support along stairs or in bathrooms, flooring material, and transitions were significant concerns raised by participants pre-surgery. Size and layout of home and ergonomics of resting furniture were recognized as issues post-surgery. Modifications ranged from easy fixes like rearranging furniture, removing clutter, installing grab bars to high-cost structural changes like remodeling critical spaces like bathrooms. Although participants agreed on the importance of conducting proactive home assessments and modifications before surgery, perceived costs, and lack of knowledge or services limit older adults from implementing some changes.

DISCUSSION AND IMPLICATIONS

Home modifications must be considered proactively before an event such as a THA or TKA. These should be done within the context of the specific needs, abilities, financial capabilities, and social and physical home environments of the individual and the residential caregivers.

Predictors of Health-Related Quality of Life After Revision Total Hip Arthroplasty for Aseptic Loosening

BACKGROUND

Few studies have investigated the relationships between preoperative or intraoperative patient factors and postoperative quality of life (QOL) after revision total hip arthroplasty (THA). The aim of our study was to identify the predictors of QOL after revision THA for aseptic loosening.

MATERIALS AND METHODS

Fifty-one patients who underwent revision THA for aseptic loosening were included in the present study. Preoperative hip function was evaluated using the Japanese Orthopaedic Association (JOA) score. The patients' QOL after surgery was evaluated with EuroQol 5D (EQ-5D) assessment at the end of the 2-year follow-up. The patients were then divided into two groups: good QOL (score ≥ 0.6) and poor QOL (score < 0.6). Predictive factors (i.e., age, BMI, preoperative JOA score, and the degree of acetabular bone defect according to the Paprosky classification) were compared between both QOL groups. Furthermore, multiple linear regression was performed to assess independent factors affecting the QOL.

RESULTS

Significant differences between the good and poor QOL groups were identified for BMI, walking ability, and severity of acetabular bone defect (BMI: 21.5 ± 2.9 vs. 24.1 ± 4.3, P = 0.0331; walking ability: 11.5 ± 5.0 vs. 5.5 ± 4.9, P = 0.0058; acetabular bone defect: 44.4% vs. 81.0%, P = 0.0103). The walking ability independently affected the EQ-5D utility score.

CONCLUSIONS

The present study indicates that a higher BMI, lower walking ability, and more severe acetabular bone defect are predictors of lower QOL after revision THA for aseptic loosening. In particular, the walking ability was the only independent factor. Thus, surgeons should pay attention to the postoperative management of patients with these risk factors.

Total Hip Arthroplasty: Past, Present, and Future. What Has Been Achieved?

In the 1960s, Sir John Charnley introduced to clinical practice his concept of low-friction total hip arthroplasty (THA). Although early designs were plagued by poor performance and even failure, there have been steady advances in implant designs, biomaterials, surgical techniques and an understanding of the biomechanical restoration of the hip; these advances have contributed to improvements in implant survival and clinical outcomes of THA in the past three decades. With improved wear resistance and mechanical reliability, a potential to last for at least 25 to 30 years are now available for THA. In this review, we focus on the evolution of THA and review current controversies and future directions of this procedure based on a single surgeon's 29-year of experience at a single institution.

Expectations and depression in patients who have undergone total hip arthroplasty in Japan: A prospective cohort study

BACKGROUND

Patients with hip osteoarthritis may be severely depressed preoperatively due to pain and limited daily-living activities. Hence, evaluating their expectations preoperatively might underestimate their true hopes regarding the upcoming total hip arthroplasty (THA).

AIM

We aimed to assess changes in patients' level of depression, understand their expectations and fulfillment, and identify factors affecting fulfillment.

METHOD

We performed a longitudinal study of 366 Japanese patients who had undergone THA during 2005-2006. Those with THA of the contralateral hip were excluded. Patients' expectations, fulfillment, depression, and physical function were assessed perperative and at 6 weeks and one year postoperatively using our own questionnaire, the Arthritis Impact Measurement Scale 2, and by the Oxford Hip Score . Logistic regression analysis was applied to identify independent predictors of expectation fulfillment.

RESULTS

At 6 weeks, 78.1% expressed expectation fulfillment and drastic alleviation of depression. Preoperative depression and fulfillment of patient expectations at 6 weeks were significant predictors of expectation fulfillment at 1 year (95% confidence intervals: 1.01-2.48 and 2.30-9.92, respectively.

CONCLUSIONS

It is worthwhile for health providers to investigate patients' expectations early in the postoperative period by considering their preoperative depression to confirm fulfillment of expectations.

A prospective study of joint function and the quality of life of patients undergoing total joint replacement

AIMS

To investigate joint functioning and the quality of life (QOL) before and after total knee and total hip replacement and the factors that influence the QOL.

METHODS

A longitudinal study was conducted between August 2015 and January 2017. A questionnaire composed of the EQ-5D, Oxford Hip Score, and Oxford Knee Score was used to collect data before surgery and 6 weeks, 3 months, and 6 months after surgery.

RESULTS

A repeated-measures analysis of variance revealed significant differences in the EQ-5D utility index between the preoperative and all 3 postoperative periods (F = 124.195, P < .05). There were significant differences in knee functioning (F = 133.859, P < .05) and hip functioning (F = 34.717, P < .05) between the preoperative and all 3 postoperative periods. The EQ-5D utility index was significantly higher among patients undergoing total knee replacement than those undergoing total hip replacement (F = 15.490, P < .05) and higher among female than male patients (F = 7.613, P < .05). A positive correlation between the QOL and the perceived convenience of living at home was observed (P < .05).

CONCLUSIONS

The findings are expected to inform patient education for patients undergoing arthroplasty surgery.

Quality of life, effects on Asian Lifestyle, and perceived satisfaction after total hip arthroplasty in Japan and Korea

BACKGROUND

The Asian lifestyle requires deep hip flexion, which increases the risk of dislocation. Hence, Asian total hip arthroplasty (THA) patients may have problems postoperatively. This study aimed to 1) document quality of life (QoL), Asian lifestyle-related items (five postures that require deep hip flexion), and perceived satisfaction in patients who underwent THA in Japan versus Korea, 2) assess the differences in QoL and Asian lifestyle-related items by patient lifestyle, and 3) identify the factors predicting QoL.

METHODS

This cross-sectional study included 222 THA patients. Korean patients completed the questionnaires. Japanese patients were then matched with Korean patients by age, sex, and post-THA period. Assessed parameters included QoL measured by the EuroQoL, Oxford hip score (OHS), Asian lifestyle (measured by the Asian lifestyle-related items), and perceived satisfaction (measured by the five items of postoperative satisfaction). Multiple regression analysis was used to determine the predictors of QoL.

RESULTS

Compared with Korean patients, Japanese patients had better QoL, but more difficulty performing postures requiring deep hip flexion. Greater QoL was associated with greater satisfaction. The predictors of decreased QoL after THA were lower OHS in both countries, worse squatting ability in Japan, and worse leg-crossing ability in Korea.

CONCLUSIONS

In Japan and Korea, the OHS is an important predictor of QoL after THA.

Three-year follow-up study of health related QOL and lifestyle indicators for Japanese patients after total hip arthroplasty

BACKGROUND

In non-Western countries including Japan, activities requiring deep flexion of the hip joint, such as seiza (kneeling with calves tucked under the thighs and buttocks resting on the heels) and using squat toilets are commonly practiced. The purpose of this study was to assess longitudinal changes in traditional health-related quality of life measures and measures of physical functions associated with lifestyle for Japanese patients pre-surgery and after total hip arthroplasty.

METHODS

Consecutive primary total hip arthroplasty patients between July 2003 and November 2006 were eligible. Patients were measured preoperatively and at 6 weeks, 1 year and 3 years postoperatively. Patients completed the EuroQol 5D, the Western Ontario and McMaster Universities Osteoarthritis Index and items related to Japanese lifestyle activities such as squatting. Changes in these scale scores across the four time points were tested, and we examined predictive factors of EuroQol 5D score at 3-year follow-up using multiple linear regression.

RESULTS

Of 1103 eligible patients, 576 completed questionnaires at all four time points. By 6 weeks post-surgery, reductions in pain and improvements in physical function and stiffness became highly significant, and improvements continued to 3 years postoperative. In contrast, improvements were far more limited for items related to Japanese lifestyle functions such as seiza and use of a Japanese squat toilet, even 3 years after surgery. Predictive factors of EQ5D at 3-year post THA were WOMAC pain and physical function, seiza, age and comorbidity measured at 3-year post THA.

CONCLUSION

The rate of improvement in QOL requiring deep flexion of the hip joint was much slower than that in QOL related to Western lifestyle. Our study suggests a need for lifestyle modification for THA patients in the other countries where kneeling and squatting are commonly performed.

Precision and Accuracy of Measurements on CT Scout View

OBJECTIVES

The purposes of this study were to (1) investigate the limits of measurements on scout view in three computed tomography axes, x, y and z and (2) develop a model to provide better understanding of measurement accuracy.

METHODS

For the first objective, anteroposterior and lateral scout views of a Catphan phantom 200 mm in diameter and length were acquired with a GE scanner at 21 different table heights. Phantom measurements on scout view were performed by two experienced readers. The comparison of their measures provided estimation of precision. The accuracy was assessed by determining the bias, calculated as the difference between the values measured on scout view and the real phantom size. Second, a model was developed investigating the relationship between the dimensions of the object, its image, and the table height. This relationship was tested on our data.

RESULTS

Scout view measurements were precise, with less than 0.53% difference between readers. In addition, small biases of about 1 mm were detected in the z-axis, whatever the table height. In the other axes, serious biases from -13 to +73 mm were measured. Furthermore, at isocentre, overestimations up to 7 mm were shown. The results also indicated that biases in scout view measurements are because of the geometrical projection related to the object-detector distance.

CONCLUSIONS

Measurements in the table movement axis are precise and accurate, conferring to scout views an added value for preoperative planning in orthopedic surgery.
