Follow-up of individualised physical activity on prescription and individualised advice in patients with hip or knee osteoarthritis: A randomised controlled trial.

OBJECTIVE: Compare the long-term effects of two different individualised physical activity interventions in hip or knee osteoarthritis patients. DESIGN: Randomised, assessor-blinded, controlled trial. SETTING: Primary care. SUBJECTS: Patients with clinically verified hip or knee osteoarthritis, <150 min/week with moderate or vigorous physical activity, aged 40-74. INTERVENTION: The advice group (n = 69) received a 1-h information and goalsetting session for individualised physical activity. The prescription group (n = 72) received information, goalsetting, individualised written prescription, self-monitoring, and four follow-ups. MAIN MEASURES: Physical activity, physical function, pain and quality of life at baseline, 6, 12 and 24 months. RESULTS: There were only minor differences in outcomes between the two groups. For self-reported physical activity, the advice group had improved from a mean of 102 (95% CI 74-130) minutes/week at baseline to 214 (95% CI 183-245) minutes/week at 24 months, while the prescription group had improved from 130 (95% CI 103-157) to 176 (95% CI 145-207) minutes/week (p = 0.01 between groups). Number of steps/day decreased by -514 (95% CI -567-462) steps from baseline to 24 months in the advice group, and the decrease in the prescription group was -852 (95% CI -900-804) steps (p = 0.415 between groups). Pain (HOOS/KOOS) in the advice group had improved by 7.9 points (95% CI 7.5-8.2) and in the prescription group by 14.7 points (95% CI 14.3-15.1) from baseline to 24 months (p = 0.024 between groups). CONCLUSIONS: There is no evidence that individualised physical activity on prescription differs from individualised advice in improving long-term effects in patients with hip or knee osteoarthritis.

OARSI year in review 2023: Rehabilitation and outcomes.

OBJECTIVE: We systematically reviewed the literature to identify comparative studies of core treatments (exercise, education, or weight management), adjunct treatments (e.g. electrotherapeutical modalities, bracing), or multimodal treatments (core plus other treatments), for treating osteoarthritis (OA) complaints, published between 1 March 2022 and 1 March 2023. DESIGN: We searched three electronic databases for peer-reviewed comparative studies evaluating core treatments, adjunct treatments, or multimodal treatments for OA affecting any joint, in comparison to other OA treatments. Two authors independently screened records. Methodological quality was assessed using the Physiotherapy Evidence Database (PEDro) scale. A narrative synthesis focusing on pain and function outcomes was performed in studies with a mean sample size of at least 46 participants per treatment arm. RESULTS: 33 publications (28 studies), 82% with PEDro ratings of good or excellent, were eligible for narrative synthesis: 23 studies evaluated knee OA; one knee OA or chronic low back pain; two knee or hip OA; one hip OA only; and one thumb OA. No studies identified a dose, duration or type of exercise that resulted in better pain or function outcomes. Core treatments generally showed modest benefits compared to no or minimal intervention controls. CONCLUSIONS: Rehabilitation research continues to be focused on the knee. Most studies are not adequately powered to assess pain efficacy. Further work is needed to better account for contextual effects, identify treatment responder characteristics, understand treatment mechanisms, and implement guideline care.

What should a toolkit to aid the delivery of therapeutic exercise for hip and knee osteoarthritis look like? Qualitative analysis of an international survey of 318 researchers, clinicians, and consumers by the OARSI Rehabilitation Discussion Group.

BACKGROUND: We aimed to identify important components of, and practical resources relevant for inclusion in, a toolkit to aid exercise delivery for people with hip/knee osteoarthritis. METHOD: An online international multi-disciplinary survey was conducted across 43 countries (139 clinicians, 44 people with hip/knee osteoarthritis and 135 osteoarthritis researchers). Participants were presented with the seeding statement 'Practical resources to aid the implementation of exercise for people with hip/knee osteoarthritis should…' and asked to provide up to 10 open text responses. Responses underwent refinement and qualitative content analysis to create domains and categories. RESULTS: Refinement of 551 open text responses yielded 72 unique statements relevant for analysis. Statements were organised into nine broad domains, suggesting that resources to aid exercise delivery should: (1) be easily accessible; (2) be of high quality; (3) be developed by, and for, stakeholders; (4) include different ways of delivering information; (5) include different types of resources to support exercise and non-exercise components of self-management; (6) include resources on recommended exercises and how to perform/progress them; (7) include tools to support motivation and track progress; (8) include resources to enable tailoring of the programme to the individual and; (9) facilitate access to professional and peer support. CONCLUSION: Our findings identified important components of, and practical resources to include within, a toolkit to aid delivery of exercise for people with hip/knee osteoarthritis. These findings have implications for exercise providers and lay the foundation for the development of a toolkit to help ensure exercise provision aligns with current international recommendations.

[Physical rehabilitation for degenerative-dystrophic diseases of the hip joint in elderly and senile people (stage 1).]

Changes in the age structure of the planet's population are leading to an increase in the number of geriatric patients requiring replacement of large joints. Age-related weakness, loss of muscle mass, testosterone deficiency, excess weight, and the presence of concomitant diseases make the process of rehabilitation treatment labor-intensive and lead to various complications. The purpose of our work was to evaluate the effectiveness of the modernized method of physical therapy at the first stage of rehabilitation treatment in elderly and senile patients with osteoarthritis of the hip joint. All patients received standard complex therapy, including orthopedic treatment methods, drug therapy, myostimulation, massage, and manual therapy. For patients in the main group, in addition to the traditional complex, the method of physical therapy according to the stated method was added and it was recommended to wear compression hosiery (stockings) while performing the exercises. The advantage of the technique is the absence of complications and side effects, which is an important component compared to other methods of restorative treatment. Minimum costs, general availability and autonomy of performing exercises, high results achieved during the treatment process confirm the value and importance of creating similar techniques for other large joints. The developed method of physical therapy has shown its effectiveness and relevance among elderly patients and can be recommended for use among different population groups as a method of restorative treatment of osteoarthritis of the hip joint.

Effectiveness of promotion and support for physical activity maintenance post total hip arthroplasty-study protocol for a pragmatic, assessor-blinded, randomized controlled trial (the PANORAMA trial).

BACKGROUND: Total hip arthroplasty is considered an efficacious procedure for relieving pain and disability, but despite that objectively measured physical activity level remains unchanged compared to pre-surgery and is still considerably lower than that of a healthy age- and sex-matched population 6-12 months post-surgery. Since there is a graded relationship between physical activity level and functional performance, increasing physical activity may enhance the outcome of the procedure. This study aims to investigate whether promotion and support of physical activity initiated 3 months after total hip arthroplasty complementary to usual rehabilitation care can increase objective measured physical activity 6 months post-surgery. METHODS: The trial is designed as a pragmatic, parallel group, two-arm, assessor-blinded, superiority, randomized (1:1), controlled trial with post intervention follow-up 6 and 12 months after total hip arthroplasty. Home-dwelling, independent, and self-reliant patients with hip osteoarthritis are provisionally enrolled prior to surgery and re-screened about 2-3 months post-surgery to confirm eligibility. Baseline assessment is conducted 3 months post-surgery. Subsequently, patients (n=200) are randomized to either a 3-month, multimodal physical activity promotion/education intervention or control (no further attention). The intervention consists of face-to-face and telephone counselling, patient education material, pedometer, and step-counting journal. The primary outcome is objectively measured physical activity, specifically the proportion of patients that complete on average ≥8000 steps per day 6 months post-surgery. Secondary outcomes include core outcomes (i.e., physical function, pain, and patient global assessment) and health-related quality of life. Furthermore, we will explore the effect of the intervention on self-efficacy and outcome expectations (i.e., tertiary outcomes). DISCUSSION: By investigating the effectiveness of a pedometer-driven, face-to-face, and telephone-assisted counselling, behavior change intervention in complementary to usual rehabilitation, we hope to deliver applicable and generalizable knowledge to support physical activity after total hip arthroplasty and potentially enhance the outcome of the procedure.

Evaluation of a collaborative ambulatory orthopedic care program for patients with hip and knee osteoarthritis: a comparative observational cohort study.

BACKGROUND: In 2014, the novel orthopedic care program was established by the AOK health insurance fund in southern Germany to improve ambulatory care for patients with musculoskeletal disorders. The program offers extended consultation times, structured collaboration between general practitioners and specialists, as well as a renewed focus on guideline-recommended therapies and patient empowerment. The aim of this study was to assess the impact of the program on health service utilization in patients with hip and knee osteoarthritis (OA). METHODS: This retrospective cohort study, which is based on claims data, evaluated health service utilization in patients with hip and knee OA from 2014 to 2017. The intervention group comprised OA patients enrolled in collaborative ambulatory orthopedic care, and the control group received usual care. The outcomes were participation in exercise interventions, prescription of physical therapy, OA-related hospitalization, and endoprosthetic surgery rates. Generalized linear regression models were used to analyze the effect of the intervention. RESULTS: Claims data for 24,170 patients were analyzed. Data for the 23,042 patients in the intervention group were compared with data for the 1,128 patients in the control group. Participation in exercise interventions (Odds Ratio (OR): 1.781; 95% Confidence Interval (CI): 1.230-2.577; p = 0.0022), and overall prescriptions of physical therapy (Rate Ratio (RR): 1.126; 95% CI: 1.025-1.236; p = 0.0128) were significantly higher in the intervention group. The intervention group had a significantly lower risk of OA -related hospitalization (OR: 0.375; 95% CI: 0.290-0.485; p < 0.0001). Endoprosthetic surgery of the knee was performed in 53.8% of hospitalized patients in the intervention group vs. 57.5% in the control group; 27.7% of hospitalized patients underwent endoprosthetic surgery of the hip in the intervention group versus 37.0% in the control group. CONCLUSIONS: In patients with hip and knee OA, collaborative ambulatory orthopedic care is associated with a lower risk of OA-related hospitalization, higher participation in exercise interventions, and more frequently prescribed physical therapy.

Gait analysis dataset of healthy volunteers and patients before and 6 months after total hip arthroplasty.

Clinical gait analysis is a promising approach for quantifying gait deviations and assessing the impairments altering gait in patients with osteoarthritis. There is a lack of consensus on the identification of kinematic outcomes that could be used for the diagnosis and follow up in patients. The proposed dataset has been established on 80 asymptomatic participants and 106 patients with unilateral hip osteoarthritis before and 6 months after arthroplasty. All volunteers walked along a 6 meters straight line at their self-selected speed. Three dimensional trajectories of 35 reflective markers were simultaneously recorded and Plugin Gait Bones, angles, Center of Mass trajectories and ground reaction forces were computed. Gait video recordings, when available, anthropometric and demographic descriptions are also available. A minimum of 10 trials have been made available in the weka file format and C3D file to enhance the use of machine learning algorithms. We aim to share this dataset to facilitate the identification of new movement-related kinematic outcomes for improving the diagnosis and follow up in patients with hip OA.

Physical activity and health-related quality of life in men and women with hip and/or knee osteoarthritis before and after a supported self-management programme - a prospective observational study.

PURPOSE: To study differences between men and women in physical activity (PA) and health-related quality of life (HRQoL) before and after participating in a supported osteoarthritis (OA) self-management programme. MATERIALS AND METHODS: A prospective observational study using data from a Swedish National Quality Register. Patients recorded between 2008 and 2013 with hip and/or knee OA with data at baseline, at 3 and 12 months follow-up (n = 7628) were included. Outcome measures were patient-reported PA and HRQoL (EQ-5D-3L). RESULTS: A greater proportion of men (p = 0.002) changed to being physically active ≥150 min/week at 3 months follow-up. The proportion of women being physically active ≥150 min/week was larger than for men at baseline (p = 0.003) and at follow-up at 12 months (p = 0.035). Women reported lower HRQoL than men at baseline (p < 0.001), at follow-up at 3 (p < 0.001) and 12 months (p = 0.010). There were no differences between men and women in change in HRQoL at 3 (p = 0.629) and 12 months (p = 0.577) follow-up. CONCLUSIONS: This study showed differences between men and women in PA and HRQoL before and after participating in a supported OA self-management programme. These differences should be considered when supporting PA and HRQoL.Implications for rehabilitationMen with hip and/or knee osteoarthritis (OA) might need more support during rehabilitation in order to maintain or even increase physical activity (PA) in the long run.Women with hip and/or knee OA might need more support during rehabilitation in order to maintain or even increase health-related quality of life (HRQoL) in the long run.Booster sessions might be suggested in order to enable both men and women with hip and/or knee OA to sustain improvements in PA and HRQoL after participating in a supported OA self-management programme.

I exercise to postpone death - Interviews with persons with hip and/or knee osteoarthritis who are attending an osteoarthritis school.

BACKGROUND: Physical activity (PA) and exercise constitute the first line of treatment for osteoarthritis (OA) of the hip and/or knee. Even though the symptoms may vary, OA should be considered a chronic disease and therefore PA and exercise should be performed lifelong. That needs knowledge and motivation. PURPOSE: The purpose of this study was to explore and create a deeper understanding of the motivational processes for PA and exercise for persons with hip and/or knee OA who have participated in a self-management program OA school that included long-term exercise supervised by physical therapists. METHODS: Twenty-two in-depth interviews were conducted with 18 participants recruited from the OA school at a Physical Therapy Rehabilitation Clinic in Sweden. The interviews were analyzed with qualitative content analysis. RESULTS: The analysis resulted in one main theme, Developing health literacy to encourage motivational processes for PA and exercise in OA and four themes: 1) meeting an established self-management program; 2) carrying my life history; 3) understanding the intelligence of the body; and 4) growing in existential motivation. CONCLUSION: Motivation for being physically active and to exercise, the life history in relation to PA and what creates existential motivation are important areas to ask questions about when people come to OA schools. Knowledge about the signals of the body connected to OA should be implemented in OA schools in order to motivate people to live an active life despite OA. Health literacy and the awareness of how PA can postpone death are likely to be important for existential motivation.

Implementación de rehabilitación remota en artrosis bilateral de cadera / Implementation of Remote Rehabilitation in Bilateral Hip Osteoarthritis

Introducción: La pandemia causada por el COVID-19 obligó a cambiar la modalidad en la cual se llevan cabo los procesos de rehabilitación -de presencial a remoto- incluso la de aquellos tratamientos ya planificados. Objetivos: Implementar la telerehabilitación y documentar si el cambio de modalidad basada en el ejercicio terapéutico tiene efectos en los resultados de la intervención. Presentación del caso: Se presenta el caso de una paciente con osteoartritis bilateral de cadera cuya intervención de terapia física tuvo que ser modificada a una modalidad remota, debido a la pandemia por COVID-19. Conclusiones: La modalidad remota adoptada no afectó la recuperación funcional establecida en las primeras etapas. Se recomienda utilizar evaluaciones funcionales, así como considerar las condiciones en el hogar requeridas para la continuidad de las intervenciones(AU)

Introduction: The pandemic caused by COVID-19 forced to change the modality in the rehabilitation processes -from face-to-face to remote- including that of those already planned treatments. Objectives: To implement remote rehabilitation and to set down whether the change of modality based on therapeutic exercise impacts on the results of the intervention. Case report: The case of a patient with bilateral hip osteoarthritis is reported here. Her physical therapy intervention had to be modified to a remote modality, due to the COVID-19 pandemic. Conclusions: The remote modality adopted did not affect the functional recovery established in the early stages. It is recommended to use functional evaluations, as well as to consider the required conditions at home to continue the interventions(AU)

Reporting of Adverse Events in Randomized Controlled Trials of Therapeutic Exercise for Hip Osteoarthritis: A Systematic Review.

OBJECTIVE: The purpose of this study was to describe adverse events (AEs) and dropouts (DOs) in randomized controlled trials of therapeutic exercise for hip osteoarthritis (HOA) and to identify whether Consolidated Standards of Reporting Trials (CONSORT) guidelines were followed. METHODS: The Cochrane Library, Embase, PubMed, and CINAHL databases were searched. Randomized controlled trials of therapeutic exercise for HOA published in English from January 1, 1980 to August 1, 2020 were included. Studies were excluded if other interventions were provided, if participants had previous hip arthroplasty, or if AEs and DOs for HOA participants were not reported separately. The internal validity of each study (Physiotherapy Evidence Database [PEDro] scoring) was assessed, participant and intervention characteristics were extracted, and the existence of a clear statement and reasons for AEs and DOs was reported. Descriptive statistics characterized results. Data heterogeneity prohibited the use of meta-analysis. RESULTS: Fourteen studies (mean PEDro score = 7.4; range = 6-10) from 10 countries were included, with 707 participants exercising. Exercise intensity was unspecified in 72.2% of exercise arms. Six studies (42.9%) included a statement of AEs, and 32 AEs were reported. All studies had a DO statement, but 29.0% of DOs occurred for unknown reasons. Six studies (42.9%) gave reasons for DOs that could be classified as AEs in 9 participants; 41 participants (5.8%) experienced exercise-related AEs. CONCLUSION: Reports of AEs were inconsistent, some DOs were potentially misclassified, and primary components of exercise interventions were frequently unreported. Despite these limitations, the overall low number of nonserious AEs suggests that the exercise-related risk of harm is minimal for individuals with HOA. IMPACT: Understanding the risk of harm associated with exercise for HOA can better inform safe dosing of exercise, clinical implementation, and replicability. Informative, consistent reporting of AEs, DOs, and exercise is needed. Greater use of the CONSORT harms-reporting checklist is warranted.

Immediate outcomes following the GLA:D® program in Denmark, Canada and Australia. A longitudinal analysis including 28,370 patients with symptomatic knee or hip osteoarthritis.

OBJECTIVE: To report outcomes across three countries for patients with symptomatic knee or hip OA attending the evidence-based education and exercise therapy program Good Life with osteoArthritis from Denmark (GLA:D®). DESIGN: GLA:D® is a structured treatment program including 2-3 patient education sessions and 12 supervised exercise sessions delivered over 8 weeks by certified health care practitioners. The program was introduced in Denmark in 2013, in Canada 2015 and in Australia 2016. Absolute mean change in pain intensity, number of chair stands in 30 s, 40 m walk test time and Knee injury and Osteoarthritis Outcome Score (KOOS)/Hip dysfunction and Osteoarthritis Outcome Score (HOOS) QOL subscale scores from baseline to immediately after treatment were reported as means and 95 % CIs and proportion of responders for each country. RESULTS: Patients from the three countries improved 26-33% in mean pain intensity, 8-12% in walking speed, 18-30% in chair stand ability and 12-26% in joint-related quality of life from baseline to immediately after treatment, with no clinically relevant differences between patients with hip and knee OA. These improvements correspond with moderate to large within-group effect sizes and 43-47 % of the patients experienced clinically relevant pain reductions. CONCLUSION: About half or more of patients across the three countries were categorized as responders for pain and objective function following the implementation of GLA:D®. These findings indicate positive patient outcomes associated with GLA:D® participation across varying health care systems from implementation of guideline-based patient education and exercise therapy for knee and hip OA.

Patients use fewer analgesics following supervised exercise therapy and patient education: an observational study of 16 499 patients with knee or hip osteoarthritis.

OBJECTIVES: To investigate changes in analgesic use before and after supervised exercise therapy and patient education in patients with knee or hip osteoarthritis (OA). METHODS: We recruited 16 499 of 25 933 eligible patients (64%; mean age 64.9; SD 9.6; 73% women) from the Good Life with osteoArthritis in Denmark (GLA:D) registry. Change in proportions of analgesic users (categorised according to analgesic risk profile; opioids > non-steroidal anti-inflammatory drugs > paracetamol) was assessed from before to after an 8-week supervised exercise therapy and patient education programme targeting knee or hip OA pain and functional limitations. RESULTS: Patients reported 13.2 mm (95% CI 12.8 to 13.6) less pain (visual analogue scale 0-100 mm) at follow-up compared with baseline. The proportion of analgesic users reduced from 62.2% (95% CI 61.5 to 63.0) at baseline to 44.1% (95% CI 43.3 to 44.9) at follow-up (absolute change: 18.1% (95% CI 17.3 to 19.0)). Among patients using analgesics at baseline, 52% changed to a lower risk analgesic or discontinued analgesic use. The proportion of opioid users after the exercise therapy was 2.5% (95% CI 2.1 to 2.9) lower than baseline; this represents a relative reduction of 36%. CONCLUSION: Among patients with knee or hip OA using analgesics, more than half either discontinued analgesic use or shifted to lower risk analgesics following an 8-week structured exercise therapy and patient education programme (GLA:D). These data encourage randomised controlled trial evaluation of whether supervised exercise therapy, combined with patient education, can reduce analgesic use, including opioids, among patients with knee and hip OA pain.

Guidance for Implementing Best Practice Therapeutic Exercise for Patients With Knee and Hip Osteoarthritis: What Does the Current Evidence Base Tell Us?

Therapeutic exercise is a recommended first-line treatment for patients with knee and hip osteoarthritis (OA); however, there is little specific advice or practical resources to guide clinicians in its implementation. As the first in a series of projects by the Osteoarthritis Research Society International Rehabilitation Discussion Group to address this gap, we aim in this narrative review to synthesize current literature informing the implementation of therapeutic exercise for patients with knee and hip OA, focusing on evidence from systematic reviews and randomized controlled trials. Therapeutic exercise is safe for patients with knee and hip OA. Numerous types of therapeutic exercise (including aerobic, strengthening, neuromuscular, mind-body exercise) may be utilized at varying doses and in different settings to improve pain and function. Benefits from therapeutic exercise appear greater when dosage recommendations from general exercise guidelines for healthy adults are met. However, interim therapeutic exercise goals may also be useful, given that many barriers to achieving these dosages exist among this patient group. Theoretically-informed strategies to improve adherence to therapeutic exercise, such as patient education, goal-setting, monitoring, and feedback, may help maintain participation and optimize clinical benefits over the longer term. Sedentary behavior is also a risk factor for disability and lower quality of life in patients with knee and hip OA, although limited evidence exists regarding how best to reduce this behavior. Current evidence can be used to inform how to implement best practice therapeutic exercise at a sufficient and appropriate dose for patients with knee and hip OA.

Associations between comorbidities and immediate and one-year outcomes following supervised exercise therapy and patient education - A cohort study of 24,513 individuals with knee or hip osteoarthritis.

OBJECTIVE: To investigate if comorbidities are associated with change in health outcomes following an 8-week exercise and education program in knee and hip osteoarthritis (OA). METHODS: We included 24,513 individuals with knee or hip OA from the Good Life with osteoArthritis in Denmark (GLA:D®). GLA:D® consists of two patient education sessions and 12 supervised exercise sessions. Before the program, individuals self-reported having one or more of 11 common comorbidities. Physical function was assessed using the 40-m Fast-Paced Walk Test (FPWT, m/sec) before and immediately after the program. Pain intensity and health-related quality of life was self-reported before, immediately after, and at 12 months post-intervention using a visual analogue scale (VAS, 0-100) and the EQ-5D-5L index (-0.624 to 1.000), respectively. Associations of comorbidity combinations with change in outcomes immediately and at 12 months was estimated using mixed linear regression. RESULTS: Individuals with OA improved on average 0.12 m/s (95%CI 0.12 to 0.13) in 40-m FPWT, -12.7 mm (95%CI -13.2 to -12.2) in VAS, and 0.039 (95%CI 0.036 to 0.041) in EQ-5D-5L from before to immediately after the intervention with minor additional improvements at 12 months. Despite that individuals with comorbidities had worse baseline scores in all outcomes than individuals without comorbidities, they had similar levels of improvement immediately and 12 months after the intervention. CONCLUSION: Comorbidities are not associated with worse nor better health outcomes following an 8-week exercise and education program in individuals with OA, suggesting exercise as a viable treatment option for individuals with OA, irrespective of comorbidities.

Are education, exercise and diet interventions a cost-effective treatment to manage hip and knee osteoarthritis? A systematic review.

OBJECTIVE: To identify research gaps and inform implementation we systematically reviewed the literature evaluating cost-effectiveness of recommended treatments (education, exercise and diet) for the management of hip and/or knee OA. METHODS: We searched Medline, Embase, Cochrane Central Register of Controlled Trials, National Health Services Economic Evaluation Database, and EconLit from inception to November 2019 for trial-based economic evaluations investigating hip and/or knee OA core treatments. Two investigators screened relevant publications, extracted data and synthesized results. Risk of bias was assessed using the Consensus on Health Economic Criteria list. RESULTS: Two cost-minimization, five cost-effectiveness and 16 cost-utility analyses evaluated core treatments in six health systems. Exercise therapy with and without education or diet was cost-effective or cost-saving compared to education or physician-delivered usual care at conventional willingness to pay (WTP) thresholds in 15 out of 16 publications. Exercise interventions were cost-effective compared to physiotherapist-delivered usual care in three studies at conventional WTP thresholds. Education interventions were not cost-effective compared to usual care or placebo at conventional WTP thresholds in three out of four publications. CONCLUSIONS: Structured core treatment programs were clinically effective and cost-effective, compared to physician-delivered usual care, in five health care systems. Providing education about core treatments was not consistently cost-effective. Implementing structured core treatment programs into funded clinical pathways would likely be an efficient use of health system resources and enhance physician-delivered usual primary care.

General, 21-Day Postoperative Rehabilitation Program Has Beneficial Effect on Oxidative Stress Markers in Patients after Total Hip or Knee Replacement.

Imbalance in prooxidant-antioxidant equilibrium plays an important role in the progression of osteoarthritis (OA). Postoperative rehabilitation significantly improves the functional activity of patients with OA. We aimed to assess the effect of the general 21-day postoperative rehabilitation on the oxidative stress markers in patients after total hip arthroplasty or knee replacement. Patients (n =41) started individually designed postoperative rehabilitation ca. 90 days after endoprosthesis implantation. We used the six-minute walk test (6MWT) to quantify the changes in their exercise capacity. We analyzed the oxidative stress markers: total antioxidant capacity (TAC), total superoxide dismutase (SOD), Cu-Zn-superoxide dismutase (CuZnSOD) and ceruloplasmin (Cp) activity, malondialdehyde (MDA) and lipofuscin (LPS) concentration in patients serum to asses changes in the oxidative stress intensity. We found that after 21-days postoperative rehabilitation program: the average distance walked by patients increased by 69 m; TAC increased by 0.20 ± 0.14 mmol/l; both SOD isoforms activities increased by 1.6 (±1.7) and 1.72 (±1.5) NU/ml, respectively; but Cp activity decreased by 1.8 (0.7-3.7) mg/dl. Also, we observed lower concentrations of lipid peroxidation markers: by 19.6 ± 24.4 µmol/l for MDA and by 0.4 ± 0.5 RF for LPS. A 21-day postoperative rehabilitation program effectively reduces oxidative processes, which helps the patients after total hip or knee replacement in a successful recovery.

Effectiveness of supervised resistance training for patients with hip osteoarthritis - a systematic review.

INTRODUCTION: The overall effectiveness of supervised progressive resistance training among patients with hip osteoarthritis is only scarcely investigated. The objective of this study was to estimate the effectiveness of supervised progressive resistance training compared with common treatment for patients with hip osteoarthritis, focusing on patient-reported function, pain, health-related quality of life, performance-based function at end of treatment and patient-reported function at 6-12 months. METHODS: This was a systematic review and meta-analysis. A systematic search was performed on 30 January 2019 in eight electronic databases (Medline, Embase, Cochrane, Pedro, AMED, Scopus, SPORTDiscus and Cinahl). The methodology of the included studies and the overall quality of evidence was assessed using the Cochrane Risk of Bias tool and the Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: A total of 189 participants with hip osteoarthritis > 50 years of age were included in the three studies. A significant difference in favour of the supervised progressive resistance groups was found in patient-reported function (weighted mean difference (MD) = 9.13 (95% confidence interval (CI): 4.45-13.80)), hip-related pain (weighted MD = 7.83 (95% CI: 2.64-13.02)) and health-related quality of life (weighted MD = 6.80 (95% CI: 1.96-11.63)) at end of treatment. The overall quality of evidence was downgraded to low due to a lack of blinding in the included studies and due to imprecision. CONCLUSIONS: Supervised progressive resistance training might be of clinical relevance for patients with hip osteoarthritis and was effective in improving patient-reported function, hip-related pain and health-related quality of life. The level of evidence is low and future studies may therefore affect the findings reported herein.
