J Orthop Surg Res 2024; 19:477. [PMID: 39138567 PMCID: PMC11321123 DOI: 10.1186/s13018-024-04982-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2024] [Accepted: 08/06/2024] [Indexed: 08/15/2024] Open
Abstract
BACKGROUND This study investigates the effectiveness of a self-developed intelligent monitoring system for home-based knee rehabilitation following total knee arthroplasty (TKA). METHODS In this randomized controlled trial, 120 patients undergoing TKA were divided using random digit allocation. Preoperative and one-month postoperative assessments of knee function, quality of life, and isometric knee extension strength were conducted with the Intelligent Monitoring System. Patients received group-specific rehabilitation instructions pre-discharge and performed exercises for one month. RESULTS Changes in isometric knee extensor strength on the affected side within one month post-surgery for the brace-monitored rehabilitation group showed a significant decrease three days after surgery compared to one day before surgery. Subsequent measurements taken at postoperative days 5, 7, 14, and 21 indicated a gradual increase in strength, although these increases did not reach statistical significance when compared with previous measurements. One month post-surgery, all groups demonstrated significant improvements in knee joint function and mobility compared to pre-surgery levels. Notably, the brace-monitored group showed statistically significant improvements in 36-Item Short-Form Health Survey (SF-36) scores over the conventional rehabilitation group. CONCLUSIONS The Intelligent Monitoring System provides effective real-time monitoring and guidance for home-based knee rehabilitation post-TKA. It significantly enhances knee joint function, isometric knee extension strength, and quality of life shortly after surgery compared to traditional rehabilitation methods. This system offers a promising approach for improving postoperative recovery in TKA patients. TRIAL REGISTRATION This study was approved by the Medical Ethics Committee of Xiangya Hospital, Central South University (Ethics Approval Number 202209008-2). It was registered with the China Clinical Trial Registry, a primary registry of the World Health Organization's International Clinical Trials Registry Platform (Registration Number ChiCTR2300068852).

[PMID: 38902382 PMCID: PMC11190212 DOI: 10.1038/s41598-024-64836-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Accepted: 06/13/2024] [Indexed: 06/22/2024] Open
Abstract
To understand the status of sedentary behaviour in elderly patients after total knee arthroplasty and analyse its influencing factors so as to provide a reference for developing targeted interventions. Conveniently selected elderly patients undergoing total knee arthroplasty (> 6 months) in a tertiary hospital in Jiangsu Province were investigated using a general information questionnaire, the Charlson Comorbidity Index, patients' self-reported sedentary behaviour information, the WOMAC Score, The Groningen Orthopaedic Social Support Scale, and Lee's Fatigue. The median daily sedentary time was 5.5 h (4.5 h, 6.625 h) in 166 elderly patients after total knee arthroplasty, of whom 82 (49.40%) showed sedentary behaviour (≥ 6 h per day). Logistic regression analysis showed that being retired/unemployed (OR = 8.550, 95% CI 1.732-42.207, P = 0.0084), having a CCI score ≥ 3 (OR = 9.018, 95% CI 1.288-63.119, P < 0.0001), having high WOMAC scores (OR = 1.783, 95% CI 1.419-2.238, P < 0.0001), having a high social support score (OR = 1.155, 95% CI 1.031-1.294, P = 0.0130), and having a fatigue score ≥ 5 (OR = 4.848, 95% CI 1.084-21.682, P = 0.0389) made patients more likely to be sedentary. The sedentary time of elderly patients after total knee arthroplasty is long, and sedentary behaviour is common among them. Healthcare professionals should develop targeted sedentary behaviour interventions based on the influencing factors of sedentary behaviour in order to reduce the occurrence of sedentary behaviour in elderly patients after total knee arthroplasty.

Abstract
BACKGROUND Knee pain is a prominent concern among older individuals, influenced by the central nervous system. This study aimed to translate the Central Aspects of Pain in the Knee (CAP-Knee) questionnaire into Japanese and investigate its reliability and validity in older Japanese individuals with knee pain. METHODS Using a forward-backward method, CAP-Knee was translated into Japanese, and data from 110 patients at an orthopedic clinic were analyzed. The Japanese version (CAP-Knee-J) was evaluated regarding pain intensity during walking, central sensitization inventory, and pain catastrophizing scale. Statistical analyses confirmed internal validity and test-retest reliability. Concurrent validity was assessed through a single correlation analysis between CAP-Knee-J and the aforementioned measures. Exploratory factor analysis was employed on each CAP-Knee-J item to examine structural validity. RESULTS CAP-Knee-J showed good internal consistency (Cronbach's α = 0.86) and excellent test-retest reliability (intraclass correlation coefficient = 0.77). It correlated significantly with pain intensity while walking, central sensitization inventory scores, and pain catastrophizing scale scores. Exploratory factor analysis produced a three-factor model. CONCLUSIONS CAP-Knee-J is a reliable and valid questionnaire for assessing central pain mechanisms specific to knee pain in older Japanese individuals, with moderate correlations with the CSI and weak with the PCS, thus indicating construct validity. This study supports the development of effective knee pain treatments and prognosis predictions.

March MK, Harmer AR, Thomas B, Maitland A, Black D, Dennis S. Does resilience predict hospital length of stay after total knee arthroplasty? A prospective observational cohort study. ARTHROPLASTY 2022; 4:27. [PMID: 35794680 PMCID: PMC9261017 DOI: 10.1186/s42836-022-00128-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 05/25/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
Resilience, or the ability to bounce back from stress, is a key psychological factor that is associated with ongoing functional independence and higher quality of life in older adults in the context of chronic health conditions. Emerging research has explored resilience and patient-reported outcomes after TKA. Our primary aim was to explore the relationship between resilience and acute hospital length of stay after total knee arthroplasty (TKA).
Methods
A prospective observational study recruited 75 participants one month before total knee arthroplasty from two Australian hospitals. Two preoperative psychological measures were used: the Brief Resilience Scale, and for comparison, the Depression, Anxiety and Stress Scale-21 (DASS-21). We collected sociodemographic, medical and surgical details, patient-reported pain, function, fatigue and quality of life one month before TKA. Health service data describing acute hospital length of stay, inpatient rehabilitation use, and physiotherapy occasions of service were collected after TKA. Non-parametric analysis was used to determine any differences in length of stay between those with low or high resilience and DASS-21 scores. Secondary regression analysis explored the preoperative factors affecting acute hospital length of stay.
Results
No significant difference was detected in length of stay between those with a low or a high resilience score before TKA. However, the group reporting psychological symptoms as measured by the DASS-21 before TKA had a significantly longer acute hospital length of stay after TKA compared to those with no psychological symptoms [median length of stay 6 (IQR 2.5) days vs. 5 (IQR 2) days, respectively (Mann-Whitney U = 495.5, P=0.03)]. Multivariate regression analysis showed that anesthetic risk score and fatigue were significant predictors of length of stay, with the overall model demonstrating significance (χ2=12.426, df = 4, P=0.014).
Conclusions
No association was detected between the brief resilience score before TKA and acute hospital length of stay after TKA, however, symptoms on the DASS-21 were associated with longer acute hospital length of stay. Preoperative screening for psychological symptoms using the DASS-21 is useful for health services to identify those at higher risk of longer acute hospital length of stay after TKA.

Abstract
OBJECTIVE To determine the prevalence and predictors of physical activity, sedentary behaviour and fatigue five years after total knee replacement surgery. DESIGN A longitudinal cohort study. SETTING Community-dwelling adults who had previously undergone total knee replacement. METHODS Five-year follow-up questionnaire data were obtained from participants previously enrolled in a randomised controlled trial examining rehabilitation after total knee replacement. Main study outcomes at one year did not differ between randomisation groups, hence data were pooled for the present longitudinal analysis. Before and one and five years after surgery, participants completed questionnaires (Active Australia Survey, WOMAC, SF12 v2, demographics and fatigue). RESULTS 272/422 community-dwelling adults (45-74 years) completed the questionnaires at five years. Excessive sedentary behaviour was evident in 91% of the cohort, predicted by excessive sedentary behaviour and lack of energy at one year. Inadequate physical activity at five years was evident for 59% of the cohort, predicted by higher fatigue and comorbidity scores pre-surgery and inadequate physical activity at one year. Just under half (47%) of the cohort experienced clinically-important fatigue at five years, predicted by clinically-important fatigue before and one year after surgery, lack of sleep before surgery and physical activity one year after surgery. CONCLUSION Documenting physical activity, sedentary behaviour and fatigue before and one year after knee replacement is important to identify those at risk of longer-term inadequate physical activity, excessive sedentary behaviour and clinically-important fatigue. Interventions to maintain activity and reduce sedentary behaviour are needed to reap the potential health benefits of total knee replacement surgery.

Abstract
BACKGROUND : Lumbar disc herniation (LDH) is a common disease in orthopedics. Surgery is shown to provide significant faster relief of pain compared to conservative therapy. However, due to the influence of surgical trauma, anesthesia and other perioperative stress factors, patients may have complications. Among them, postoperative fatigue syndrome (POFS) is a common complication. Traditional Chinese medicine or integrated traditional Chinese and Western medicine have been proved to be effective in improving postoperative fatigue. METHODS : This study is a randomized controlled trial. One hundred eighty Chinese patients with POFS of LDH will be randomly divided into control group, experimental group 1, experimental group 2 and experimental group 3 according to the ratio of 1:1:1:1. The patients in the control group will be treated with conventional treatment after operation, the patients in the experimental group 1 will be treated with acupoint massage, the patients in the experimental group 2 will be treated with relaxation therapy, and the patients in the experimental group 3 will be treated with acupoint massage combined with relaxation therapy. The whole treatment will last for 5 days. The main outcome measures will be fatigue visual analogue scale and identity-consequence fatigue scale, and the secondary outcome measures will be hospital anxiety and depression scale. DISCUSSION : This study is to observe the effects of acupoint massage comblined with relaxation therapy on reducing postoperative fatigue of lumbar disc herniation surgical patients.

Abstract
AIM The aim of the study was to identify sociodemographic, disease-related, physical and mental health-related determinants of fatigue at 2-year follow-up in individuals with symptomatic knee osteoarthritis (OA). METHODS A longitudinal analysis of participants with symptomatic knee OA from the Multicenter Osteoarthritis Study (MOST) was conducted to identify predictors of fatigue at 2-year follow-up. Participants self-reported fatigue at baseline for the first time in the MOST cohort and at follow-up using a 0-10 visual analog scale. At baseline, questionnaires on sociodemographics, disease-related symptoms, physical and mental health factors were completed. Data were analyzed using linear regressions with a backwards elimination approach. RESULTS Of the 2330 individuals in the MOST cohort at baseline, 576 had symptomatic knee OA and of these, 449 with complete fatigue values at baseline and follow-up were included in this analysis. Minimally important fatigue change (ie, worsening [≥1.13], no change [<0.82 or <1.13] and improvement [≥-0.82]) from baseline to follow-up were unequal within the population (34.5%, 26.9%, 38.5%; χ2 [2, N = 449] = 9.32, P = .009). The multiple linear regression showed that baseline fatigue (unstandardized coefficient [Β] = 0.435; 95% confidence interval [CI] 0.348-0.523, P < .001), slow gait speed (Β = -1.124; 95% CI -1.962 to -0.285, P = .009), depressive symptoms (Β = 0.049; 95% CI 0.024-0.075, P < .001) and higher numbers of comorbidities (Β = 0.242; 95% CI 0.045-0.439, P = .016) were significant predictors of greater fatigue at follow-up. CONCLUSION Fatigue is strongly associated with physical- and mental-related health factors. Individualized treatments that include combined psychological and physical function rehabilitation might be modalities for fatigue management.

Abstract
Chronic illness has a significant effect on quality of life, and a critical measure of health outcomes. Correlations between pain, depressive symptoms, fatigue, and physical function and their direct and indirect effects on quality of life were determined among 200 Thai older population with knee osteoarthritis using the Numeric Rating Scale, the Multidimensional Assessment of Fatigue, and the Thai Geriatric Depression Scale-15. Physical function was investigated by using the Timed Up and Go test. Path analysis revealed significant negative direct paths from pain, depressive symptoms, fatigue, and Timed Up and Go test results to quality of life. Pain, fatigue, and the Timed Up and Go test results had indirect effects on quality of life, while depressive symptoms had no indirect effect on quality of life. Increases in pain, depressive symptoms, fatigue, and Timed Up and Go test results were associated with reductions in quality of life. An understanding of the complex relationship among these variables is beneficial for designing an appropriate intervention for improving quality of life among older people with knee osteoarthritis.

Abstract
OBJECTIVE This study aims to evaluate the prevalence and determinants of inadequate physical activity and excessive sedentary behaviour before and after total knee replacement. DESIGN, SETTING AND SUBJECTS Secondary analysis was performed on data from a cohort of 422 adults (45-74 years), drawn from 12 public or private hospitals, undergoing primary unilateral or bilateral total knee replacement surgery. MAIN MEASURES Questionnaires were used to determine the presence of inadequate physical activity and excessive sedentary behaviour before and 6 and 12 months after total knee replacement surgery. Knee pain, activity limitations, comorbidities, muscle strength, psychological well-being, fatigue, sleep and body mass index were measured/assessed as possible determinants of physical activity or sedentary behaviour. RESULTS Before surgery, 77% ( n = 326) of the cohort participated in inadequate physical activity according to World Health Organization guidelines, and 60% ( n = 253) engaged in excessive sedentary behaviour. Twelve months after surgery, 53% ( n = 185) of the cohort engaged in inadequate physical activity and 45% ( n = 157) in excessive sedentary behaviour. Inadequate physical activity before surgery ( P = 0.02), obesity ( P = 0.07) and comorbidity score >6 ( P = 0.04) predicted inadequate physical activity 12 months after surgery. Excessive sedentary behaviour and activity limitations before surgery predicted excessive sedentary behaviour 12 months after surgery. CONCLUSION Although there were improvements after total knee replacement, 12 months after surgery about half the cohort did not meet World Health Organization recommendations for activity. Pre-surgery assessment of physical activity, activity limitations, sedentary behaviour and body mass index is essential to identify patients at risk for long-term inactivity.
