Effect of early supervised progressive resistance training compared to unsupervised home-based exercise after fast-track total hip replacement applied to patients with preoperative functional limitations. A single-blinded randomised controlled trial

Pre-operative gluteus medius tendon degeneration and its impact on strength and functional ability one year after total hip replacement

OBJECTIVE

Hip osteoarthritis is a common cause of disability and surgery is often unavoidable. Patient satisfaction is high and functional ability improves after surgery. However, residual impairment and pain are common. Degenerative changes in tendons and muscles are probable causes. The aim of this study is to investigate gluteus medius (GMED) tendon degeneration in relation to muscle strength, physical function and walking distance before and one year after total hip replacement.

MATERIAL AND METHODS

In total, 18 patients were examined pre- and post-operatively, of whom 15 were available in the final analysis. Muscle strength, physical function and walking distance were assessed. Tendon biopsies were assessed microscopically, and the total degeneration score (TDS) was calculated.

RESULTS

A correlation between the TDS and muscle strength was found for the hamstrings, GMED and quadriceps pre- or post-operatively. No correlations were found between the TDS and functional ability. Functional ability and muscle strength improved significantly after surgery.

CONCLUSION

Our results indicate a correlation between tendon degeneration and the muscle strength of the hip and knee in patients with hip OA and one year after THR. To minimise post-operative residual discomfort, rehabilitation programs should probably be modified over time to match the pre- and post-operative needs. Further studies are needed.This study was registered at https://www.researchweb.org/is/vgr/project/279039 (in Swedish).

Clinical benefit of physical rehabilitation after total hip and knee arthroplasty: A pragmatic, randomized, controlled trial (The DRAW1 trial)

Importance

Comparative effectiveness trials have not shown superiority of one type of physical rehabilitation over another following total hip (THA) and knee (TKA) arthroplasty. We therefore ask the fundamental effectiveness question: Does physical rehabilitation "work" better than no physical rehabilitation?

Objective

To compare the effectiveness of a 6-week program of physical rehabilitation (home-based telerehabilitation, or home-based rehabilitation) to no physical rehabilitation following THA and TKA.

Design

3-arm,randomized, controlled, superiority trial with blinded outcome assessments. 377 patients (210 THA/167 TKA) were screened for eligibility before the targeted sample size of 168 patients was reached. Outcome measures were assessed at baseline, at the end of intervention (6 weeks), and 3 and 12 months postoperatively. The primary outcome was the Hip disability and Osteoarthritis Outcome Score (HOOS)/Knee injury and Osteoarthritis Outcome Score (KOOS)-subscale: function in daily living. Secondary outcomes included: HOOS/KOOS-subscales: pain, symptoms, and quality of life, patient global assessment, analgesics, walking aids, 30-s chair stand test, 4 ​× ​10 ​m fast-paced walk test, exercise adherence, and satisfaction.

Results

Comparing physical rehabilitation (home-based telerehabilitation, and home-based rehabilitation) to no physical rehabilitation, the mean group-differences for the primary outcome were 3.3 (95%CI: -1.9 to 8.6; p ​= ​0.10) points at 6 weeks, and 1.9 (95%CI: -3.7 to 7.6; p ​= ​0.25) and 2.6 (95%CI: -4.4 to 9.6; p ​= ​0.23) points at the 3- and 12-months follow-ups, respectively.

Conclusion

Physical rehabilitation was not superior to the no physical rehabilitation comparator following THA or TKA in terms of self-reported function or any of the secondary outcomes.

Functional assessment in patients undergoing total hip arthroplasty

Aims

Conventional patient-reported surveys, used for patients undergoing total hip arthroplasty (THA), are limited by subjectivity and recall bias. Objective functional evaluation, such as gait analysis, to delineate a patient's functional capacity and customize surgical interventions, may address these shortcomings. This systematic review endeavours to investigate the application of objective functional assessments in appraising individuals undergoing THA.

Methods

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were applied. Eligible studies of THA patients that conducted at least one type of objective functional assessment both pre- and postoperatively were identified through Embase, Medline/PubMed, and Cochrane Central database-searching from inception to 15 September 2023. The assessments included were subgrouped for analysis: gait analysis, motion analysis, wearables, and strength tests.

Results

A total of 130 studies using 15 distinct objective functional assessment methods (FAMs) were identified. The most frequently used method was instrumented gait/motion analysis, followed by the Timed-Up-and-Go test (TUG), 6 minute walk test, timed stair climbing test, and various strength tests. These assessments were characterized by their diagnostic precision and applicability to daily activities. Wearables were frequently used, offering cost-effectiveness and remote monitoring benefits. However, their accuracy and potential discomfort for patients must be considered.

Conclusion

The integration of objective functional assessments in THA presents promise as a progress-tracking modality for improving patient outcomes. Gait analysis and the TUG, along with advancing wearable sensor technology, have the potential to enhance patient care, surgical planning, and rehabilitation.

Effect of an exercise intervention targeting hip strengthening in patients undergoing revision total hip replacement-A study protocol for a multicenter randomized controlled trial

BACKGROUND

Limited evidence exists regarding the effectiveness of pain relief and functional improvement in patients undergoing revision total hip replacement (THR). Furthermore, there are no clinical guidelines or consensus on optimal rehabilitation after revision THR.

PURPOSE

The primary aim of this study was to compare the effectiveness of an exercise intervention targeting hip strengthening with standard community-based rehabilitation in patients undergoing revision THR.

METHODS

This multicenter randomized controlled assessor-blinded trial will be conducted at eight hospitals and multiple municipality rehabilitation centers in Denmark. A total of 84 patients undergoing revision THR are estimated to be allocated to either an exercise intervention targeting hip strengthening (NEMEX-STR) or standard community-based rehabilitation (Usual care). Recruitment was initiated in November 2022 and is expected to be completed by June 2024. The primary outcome is change in functional performance measured by the 30 s chair stand test, from baseline to 4 months after the start of intervention. Secondary outcomes include hip disability and osteoarthritis outcome score; 40 m fast-paced walk test; 9-step timed stair climb test; leg extensor muscle power; global perceived effect; and adverse events. Other outcomes include The International Physical Activity Questionnaires, pain intensity, and European quality of life-5 dimensions. An intention-to-treat approach will be used for analyzing changes in primary and secondary outcome measures. The trial was approved by the Central Denmark Region Committees on Health Research Ethics (Journal No 1-10-72-134-22) and registered on the Central Denmark Regions' internal list of research projects (Journal No 1-16-02-285-22).

DISCUSSION

To our knowledge, this study is the first to explore different rehabilitation programs after revision THR through a randomized controlled trial. The results will provide clinically relevant evidence for optimal rehabilitation after revision THR for improving functional performance, physical function, and quality of life, with great importance for patients, relatives, physiotherapists, and decision-makers.

Effectiveness of Telerehabilitation Programs in Elderly with Hip or Knee Arthroplasty: A Systematic Review

Background: Lower limb osteoarthritis (OA) often generates musculoskeletal pain causing functional impairment and decreasing mobility, autonomy, and quality of life. Patients with OA are commonly prescribed specific care for total hip arthroplasty or total knee arthroplasty (THA or TKA), when patients present symptoms that are refractory to nondrug treatments. Currently, when patients are discharged from orthopedic surgery, they are either referred to a rehabilitation department, or sent directly home with assistance such as remote monitoring by teleconsultation or a mobile application. In recent years, there has been an evolution in digital health and in particular telerehabilitation. To determine utility and effectiveness, the aim of this systematic review was to highlight and evaluate different telerehabilitation programs using new information and communication technologies. Methods: Five databases, ScienceDirect, PubMed, Web of Sciences, Scopus, and Google scholar, were searched until 30 June 30, 2023. All studies written in English and meeting our inclusion criteria were included. Databases were screened for "Total Hip Arthroplasty," "Total Knee Arthroplasty," "Total Hip Replacement," "Total Knee Replacement," "Rehabilitation," "Physical Activity," "Physiotherapy," "Telerehabilitation," "Telecommunication*," "Senior*," and "Elderly" in accordance with PRISMA-ScR guideline. Results: Fourteen articles were selected according to inclusion criteria. Telerehabilitation was offered in seven different ways (video call, applications smartphones, website, etc.). Assessments included were mainly quality of life questionnaires, perceived effort after exercises, field surveys on the tool experience, and physical tests to assess motor functions. Conclusion: This review highlights the importance and relevance of evaluating the contributions and limits of new health technologies to improve patient monitoring and thus enable better remote clinical care.

Effects of home-based prehabilitation on pre- and postoperative outcomes following total hip and knee arthroplasty

The aim of this study was to determine the effectiveness of home-based prehabilitation on pre- and postoperative outcomes in participants awaiting total knee (TKA) and hip arthroplasty (THA). A systematic review with meta-analysis of randomized controlled trials (RCTs) of prehabilitation interventions for TKA and THA. MEDLINE, CINAHL, ProQuest, PubMed, Cochrane Library, and Google Scholar databases were searched from inception to October 2022. Evidence was assessed by the PEDro scale and the Cochrane risk-of-bias (ROB2) tool. A total of 22 RCTs (1,601 patients) were identified with good overall quality and low risk of bias. Prehabilitation significantly improved pain prior to TKA (mean difference (MD) -1.02: p = 0.001), with non-significant improvements for function before (MD -0.48; p = 0.06) and after TKA (MD -0.69; p = 0.25). Small preoperative improvements were observed for pain (MD -0.02; p = 0.87) and function (MD -0.18; p = 0.16) prior to THA, but no post THA effect was found for pain (MD 0.19; p = 0.44) and function (MD 0.14; p = 0.68). A trend favouring usual care for improving quality of life (QoL) prior to TKA (MD 0.61; p = 0.34), but no effect on QoL prior (MD 0.03; p = 0.87) or post THA (MD -0.05; p = 0.83) was found. Prehabilitation significantly reduced hospital length of stay (LOS) for TKA (MD -0.43 days; p < 0.001) but not for THA (MD, -0.24; p = 0.12). Compliance was only reported in 11 studies and was excellent with a mean value of 90.5% (SD 6.82). Prehabilitation interventions improve pain and function prior to TKA and THA and reduce hospital LOS, though it is unclear if these effects enhance outcomes postoperatively.

Rehabilitation for Total Hip Arthroplasty: A Systematic Review

ABSTRACT

We sought to determine the comparative benefits and harms of rehabilitation interventions for patients who have undergone elective, unilateral THA surgery for the treatment of primary osteoarthritis. We searched PubMed, Embase, The Cochrane Register of Clinical Trials, CINAHL, PsycINFO, Scopus, and ClinicalTrials.gov from January 1, 2005, through May 3, 2021. We included randomized controlled trials and adequately adjusted nonrandomized comparative studies of rehabilitation programs reporting performance-based, patient-reported, or healthcare utilization outcomes. Three researchers extracted study data and assessed risk of bias, verified by an independent researcher. Experts in rehabilitation content and complex interventions independently coded rehabilitation interventions. The team assessed strength of evidence. Large heterogeneity across evaluated rehabilitation programs limited conclusions. Evidence from 15 studies suggests that diverse rehabilitation programs may not differ in terms of risk of harm or outcomes of pain, strength, activities of daily living, or quality of life (all low strength of evidence). Evidence is insufficient for other outcomes. In conclusion, no differences in outcomes were found between different rehabilitation programs after THA. Further evidence is needed to inform decisions on what attributes of rehabilitation programs are most effective for various outcomes.

The relationship between muscle power, functional performance, accelerometer-based measurement of physical activity and patient-reported outcomes in patients with hip osteoarthritis: A cross-sectional study

BACKGROUND

Patients with unilateral hip osteoarthritis appear to have between-leg differences in leg extension power (LEP). The Nottingham Leg Extensor Power Rig provides reliable and valid results but requires sensitive equipment. It would be relevant to identify measures closely associated with this test.

OBJECTIVE

(i) To investigate if LEP is lower in the affected leg compared to the non-affected leg. Furthermore, to investigate the associations between LEP and the measures: (ii) Functional performance, (iii) accelerometer-based measurement of physical activity and (iv) patient-reported outcome measures (PROM).

DESIGN

Cross-sectional study including 60 patients (30 men, 30 women) with hip osteoarthritis scheduled for hip replacement.

METHOD

The counter movement jump and 10-m sprint tests were used to determine functional performance, accelerometer-sensors were used to determine physical activity and the Copenhagen Hip and Groin Outcome Score (HAGOS) was used to determine PROM.

RESULTS

(i) LEP in the affected leg corresponded to 79% [95% CI 74%; 85%] of the non-affected leg, (ii) LEP was positively associated with functional performance tests (β 0.63 to 0.78, p < 0.05), (iii) positively associated although non-significantly with physical activity (β 0.16 to 0.23, p > 0.05) and (iv) positively associated with the six HAGOS subscales (β 0.25 to 0.54, p < 0.05).

CONCLUSION

Functional performance tests may be used as feasible, inexpensive and fast ways to assess LEP in clinical settings. These results may suggest that interventions aimed at improving LEP can improve functional performance and PROM, but not physical activity. Future research is needed to confirm the causality of these cross-sectional findings.

Unsupervised Home Exercises Versus Formal Physical Therapy After Primary Total Hip Arthroplasty: A Systematic Review

Historically, postoperative exercise and physical therapy (PT) have been viewed as crucial to a successful outcome following primary total hip arthroplasty (THA). This systematic review and meta-analysis aimed to assess differences in both short- and long-term objective and self-reported measures between primary THA patients with formal supervised physical therapy versus unsupervised home exercises after discharge. A search was conducted of six electronic databases from inception to December 14, 2020, for randomized controlled trials (RCTs) comparing changes from baseline in lower extremity strength (LES), aerobic capacity, and self-reported physical function and quality of life (QoL) between supervised and unsupervised physical therapy/exercise regimens following primary THA. Outcomes were separated into short-term (<6 months from surgery, closest to 3 months) and long-term (≥6 months from surgery, closest to 12 months) measures. Meta-analyses were performed when possible and reported in standardized mean differences (SMDs) with 95% confidence intervals (CI). Seven studies (N=398) were included for review. No significant differences were observed with regard to lower extremity strength (p=0.85), aerobic capacity (p=0.98), or short-term quality of life scores (p=0.18). Although patients in supervised physical therapy demonstrated improved short-term self-reported outcomes compared to those performing unsupervised exercises, this was represented by a small effect size (SMD 0.23 [95% CI, 0.02-0.44]; p=0.04). No differences were observed between groups regarding long-term lower extremity strength (p=0.24), physical outcome scores (p=0.37), or quality of life (p=0.14). The routine use of supervised physical therapy may not provide any clinically significant benefit over unsupervised exercises following primary THA. These results suggest that providers should reconsider the routine use of supervised physical therapy after discharge.

Key Components, Current Practice and Clinical Outcomes of ERAS Programs in Patients Undergoing Orthopedic Surgery: A Systematic Review

Enhanced recovery after surgery (ERAS) protocols have led to improvements in outcomes in several surgical fields, through multimodal optimization of patient pathways, reductions in complications, improved patient experiences and reductions in the length of stay. However, their use has not been uniformly recognized in all orthopedic fields, and there is still no consensus on the best implementation process. Here, we evaluated pre-, peri-, and post-operative key elements and clinical evidence of ERAS protocols, measurements, and associated outcomes in patients undergoing different orthopedic surgical procedures. A systematic literature search on PubMed, Scopus, and Web of Science Core Collection databases was conducted to identify clinical studies, from 2012 to 2022. Out of the 1154 studies retrieved, 174 (25 on spine surgery, 4 on thorax surgery, 2 on elbow surgery and 143 on hip and/or knee surgery) were considered eligible for this review. Results showed that ERAS protocols improve the recovery from orthopedic surgery, decreasing the length of hospital stays (LOS) and the readmission rates. Comparative studies between ERAS and non-ERAS protocols also showed improvement in patient pain scores, satisfaction, and range of motion. Although ERAS protocols in orthopedic surgery are safe and effective, future studies focusing on specific ERAS elements, in particular for elbow, thorax and spine, are mandatory to optimize the protocols.

Heterotopic Ossification: Clinical Features, Basic Researches, and Mechanical Stimulations

Heterotopic ossification (HO) is defined as the occurrence of extraskeletal bone in soft tissue. Although this pathological osteogenesis process involves the participation of osteoblasts and osteoclasts during the formation of bone structures, it differs from normal physiological osteogenesis in many features. In this article, the primary characteristics of heterotopic ossification are reviewed from both clinical and basic research perspectives, with a special highlight on the influence of mechanics on heterotopic ossification, which serves an important role in the prophylaxis and treatment of HO.

Stabilometric assessments of two rehabilitation protocols on postural parameters after posterior total hip arthroplasty: A prospective randomized comparative study

INTRODUCTION

After total hip arthroplasty (THA), patients continue to have muscular, functional and postural deficits. The literature seems to support the use of postoperative rehabilitation, especially self-directed programs. However, there is no set protocol for the management of postural disorders. Therefore, the purpose of this study was to compare postural parameters of a group of patients who underwent posterior THA followed by 2 different types of rehabilitation (stabilometric platform (SP) and home-based self-directed protocols) with a control group of operated patients who did not undergo rehabilitation and a control group of age-matched asymptomatic subjects.

HYPOTHESIS

We hypothesized that rehabilitation would normalize the stabilometric parameters.

PATIENTS AND METHODS

A total of 67 subjects were enrolled in this study (mean age 67.85±1.22years) and divided into 4 groups. Forty-one of these subjects had undergone a posterior THA were randomly assigned between D10 and D21 to one of the following 3 groups: no rehabilitation control group (THACG=14), supervised rehabilitation with a stabilometric platform group (RSPG=16), and a self-directed home-based rehabilitation group (SDHRG=11). The 4th group was a control group made up of 26 age-matched asymptomatic nonoperated subjects (CG55-80). These rehabilitation protocols lasted 3weeks. At the end of the 3weeks, the groups performed the same stabilometric single leg and double leg stance tests (considering lower limb dominance) on an SP.

RESULTS

No significant differences were observed between groups in the bipedal stance, except between the CG55-80 and the THACG, where a higher energy expenditure was observed in the THACG during the static stance with eyes open (EO) and eyes closed (EC): increase in the path length (P_length) covered by the center of pressure (COP) (EO: p=01; EC: p=03) and the average velocity (V_avg) of the COP (EO: p=01; EC: p=03). These differences were not observed in the SDHRG and RSPG whether they were compared with one another or with both control groups. In the unipedal stance, subjects in the RSPG and SDHRG showed greater muscle activity in the anterior and posterior chains and hip abductors, and used less energy to maintain the stance than those in the CG55-80, regardless of lower limb dominance: decrease in the mediolateral range of COP displacement (X_range) (hip abductor muscles) (p=02) and anteroposterior range of COP displacement (Y_range) (anterior and posterior chains) (p=3.49.10^-3), 95% confidence ellipse area (E_area) of COP data (p=1.47.10^-3), P_length (p=04) and V_avg (p=04). The RSPG had a smaller E_area than the SDHRG (p=04), demonstrating a better postural stability during the unipedal stance performed on the dominant operated leg.

DISCUSSION

Our results were consistent with the literature on the benefits of rehabilitation after THA, thus confirming our hypothesis that rehabilitation normalized stabilometric parameters between D31-D45, depending on the subjects. These results provide new information regarding rehabilitation techniques to be implemented postoperatively after a THA. A home-based self-directed rehabilitation program is just as effective as an SP program in managing postural disorders.

LEVEL OF EVIDENCE

II; randomized controlled trial with low statistical power.

Exercise as Medicine During the Course of Hip Osteoarthritis

Exercise is now considered medicine in numerous chronic conditions and is essentially without side effects. We hypothesize that exercise is primary, secondary, and tertiary prevention at different stages of hip osteoarthritis (preclinical, mild-moderate, and severe hip osteoarthritis) and after total hip arthroplasty.

Effects of progressive resistance training for early postoperative fast-track total hip or knee arthroplasty: A systematic review and meta-analysis

Progressive resistance training (PRT) is one of the most commonly used exercise methods after joint replacement, while its effectiveness and safety are still controversial. Therefore, it's vital to investigate the effect of PRT on muscle strength and functional capacity early postoperative total hip arthroplasty (THA) or total knee arthroplasty (TKA). Relevant studies were identified via a search of Medline, Web of science and Cochrane Library from 2002 to 12 May 2020. Fifteen of 704 studies which comprised 6 THAs and 8 TKAs, involving 1021 adult patients were eligible for inclusion in the meta-analysis. There were no significant differences between the two groups after TKA in the 6-min walk test (6-WMT) within 1 month (95% CI = -0.41, 1.53), within 3 months (95% CI = -0.27, 0.76), within 12 months (95% CI = -0.29, 0.66); climb performance in seconds (s) (SCP), leg extension power, timed up and go test in seconds (s) (TUG) within 1 month (95% CI = -1.75, 0.77), within 3 months (95% CI = -0.48, 0.33), within 12 months (95% CI = -0.44, 0.35), sit to stand, number of repetitions in 30s (ST). There was no difference in the incidence of adverse events (95% CI = -0.01, 0.10). Similarly, two groups were also no obvious distinction after THA in the 6-WMT, SCP, Leg extension power, ST. PRT early after THA or TKA did not differ significantly from SR in terms of functional capacity, muscle strength recovery and incidence of adverse events. PRT is one of the options for rapid rehabilitation after joint replacement.

Activity Recommendations After Total Hip and Total Knee Arthroplasty

»

A formal unsupervised activity program should be recommended to all patients recovering from total knee arthroplasty (TKA) and total hip arthroplasty (THA).

»

In a subset of all patients undergoing TKA or THA, studies have found that an unsupervised activity program may be as efficacious as supervised physical therapy (PT) after surgery. Certain patients with inadequate independent function may continue to benefit from supervised PT.

»

For TKA, supervised telerehabilitation has also been proven to be an effective modality, with studies suggesting equivalent efficacy compared with supervised in-person PT.

»

Following TKA, there is no benefit to the use of continuous passive motion or cryotherapy devices, but there are promising benefits from the use of pedaling exercises, weight training, and balance and/or sensorimotor training as adjuncts to a multidisciplinary program after TKA.

»

No standardized postoperative limitations exist following TKA, and the return to preoperative activities should be dictated by an individual's competency and should consist of methods to minimize high impact stress on the joint.

»

Despite traditional postoperative protocols recommending range-of-motion restrictions after THA, it is reasonable to recommend that hip precautions may not be needed routinely following elective primary THA.

Evaluation of Exercise Interventions and Outcomes After Hip Arthroplasty: A Systematic Review and Meta-analysis

IMPORTANCE

Preoperative and postoperative exercise interventions are commonly used in patients with total hip arthroplasty despite a lack of established efficacy.

OBJECTIVE

To explore clinical outcomes associated with exercise training before and after hip arthroplasty.

DATA SOURCES

PubMed, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, EMBASE, and Google Scholar were searched from their inception to March 2020. Reference lists of included trials and related reviews were also searched.

STUDY SELECTION

Randomized clinical trials of land-based exercise interventions before or after total hip arthroplasty were included.

DATA EXTRACTION AND SYNTHESIS

This systematic review and meta-analysis is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Data extraction was independently performed in duplicate. Random-effects meta-analyses with restricted maximum likelihood were performed for pooling the data.

MAIN OUTCOMES AND MEASURES

The primary prespecified outcome was self-reported physical function. Secondary prespecified outcomes were self-reported pain intensity, quality of life, gait speed, lower body muscle strength, lower body flexibility, anxiety, hospital length of stay, and adverse events.

RESULTS

A total of 32 randomized clinical trials with 1753 patients were included in the qualitative synthesis, and 26 studies with 1004 patients were included in the meta-analysis. Compared with usual care or no or minimal intervention, postoperative exercise training was not associated with improved self-reported physical function, with a moderate level of certainty, at 4 weeks (standardized mean difference [SMD], 0.01; 95% CI, -0.18 to 0.20), 12 weeks (SMD, -0.08; 95% CI, -0.23 to 0.07) and 26 weeks (SMD, -0.04; 95% CI, -0.31 to 0.24) postoperatively, and low level of certainty at 1 year after surgical treatment (SMD, 0.01; 95% CI, -0.09 to 0.12). For preoperative exercise interventions, there was no association of exercised training with self-reported physical function compared with the control at the 12-week (SMD, -0.14; 95% CI, -0.61 to 0.32) or 1-year follow-ups (SMD, 0.01; 95% CI, -0.37 to 0.40) with very low certainty, and no association with length of stay (mean difference, -0.21; 95% CI, -0.74 to 0.31) at moderate certainty. Results for postoperative hip muscle strength were rated at very low certainty, with no statistical significance. Meta-analysis could not be performed for other outcomes.

CONCLUSIONS AND RELEVANCE

This systematic review and meta-analysis found low- to moderate-quality evidence that postoperative exercise interventions were not associated with improved self-reported physical function compared with usual care or no or minimal intervention. Furthermore, there was very low-quality evidence that preoperative exercise programs were not associated with higher self-reported physical function and hospital length of stay compared with usual care or no or minimal intervention.

The Effect of Resistance Training on the Function after Hip Replacement: A Meta-analysis of Randomized Controlled Trials

INTRODUCTION

The efficacy of resistance training for hip replacement remains controversial. We conducted a systematic review and meta-analysis to explore the influence of resistance training on functional recovery for hip replacement.

METHODS

We searched PubMed, EMbase, Web of Science, EBSCO, and Cochrane Library databases through April 2018 for randomized controlled trials (RCTs) assessing the effect of resistance training on hip replacement.

RESULTS

Five RCTs involving 251 patients are included in the meta-analysis. Overall, compared with the control group for post-hip replacement patients, resistance training can significantly improve hip-related quality of life (standard mean difference [SMD] = 0.35; 95% CI = 0.02 to 0.68; p = 0.04), symptoms (SMD = 0.41; 95% CI = 0.08 to 0.74; p = 0.02), sports and recreation (SMD = 0.41; 95% CI = 0.08 to 0.75; p = 0.01), and reduce pain scores (SMD = 0.41; 95% CI = 0.08 to 0.74; p = 0.02), but has no remarkable impact on activities of daily living function (SMD = 0.48; 95% CI = 0 to 0.96; p = 0.05), sit to stand (SMD = 0.17; 95% CI = - 0.25 to 0.59; p = 0.44), stair climb performance (SMD = 0.06; 95% CI = - 0.36 to 0.48; p = 0.77), and leg extension power (SMD = 0.42; 95% CI = - 0.17 to 1.01; p = 0.17).

CONCLUSIONS

Resistance training is associated with significantly improved hip-related quality of life, symptoms, and sports and recreation, and decreased pain scores in post-hip replacement patients.

Clinical and cost-effectiveness of physiotherapy interventions following total hip replacement: a systematic review and meta-analysis

To examine the reported clinical and cost-effectiveness of physiotherapy interventions following total hip replacement (THR). A systematic review was completed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). MEDLINE, CINAHL, AMED, Scopus, DARE, HTA, and NHS EED databases were searched for studies on clinical and cost-effectiveness of physiotherapy in adults with THR published up to March 2020. Studies meeting the inclusion criteria were identified and key data were extracted. Risk of bias was assessed using the Cochrane Risk of Bias Tool and a Consolidated Health Economic Evaluation Reporting Standards (CHEERS). Data were summarised and combined using random-effect meta-analysis. A total of 1263 studies related to the aim of the review were identified, from which 20 studies met the inclusion criteria and were included in the review. These studies were conducted in Australia (n = 3), Brazil (n = 1), United States of America (USA) (n = 2), France (n = 2), Italy (n = 2), Germany (n = 3), Ireland (n = 1), Norway (n = 2), Canada (n = 1), Japan (n = 1), Denmark (n = 1), and United Kingdom (UK) (n = 1). The duration of follow-up of the included studies was ranged from 2 weeks to 12 months. Physiotherapy interventions were found to be clinically effective for functional performance, hip muscle strength, pain, and range of motion flexion. From the National Health Service perspective, an accelerated physiotherapy programme following THR was cost-effective. The findings of the review suggest that physiotherapy interventions were clinically effective for people with THR. However, questions remain on the pooled cost-effectiveness of physiotherapy interventions, and further research is required to examine this in patients with THR. Future studies are required to examine the cost-effectiveness of these interventions from patients, caregivers, and societal perspectives.Registration Prospero (ID: CRD42018096524).

Rationale and design of the PaTIO study: PhysiotherApeutic Treat-to-target Intervention after Orthopaedic surgery

Background

Physiotherapy is a proven effective treatment strategy after total knee and hip arthroplasty (TKA/THA), however there is considerable practice variation regarding its timing, content and duration. This study aims to compare the (cost-) effectiveness of a standardized, treat-to-target postoperative physiotherapy strategy with usual postoperative care.

Methods

Using a cluster randomized study design, consecutive patients scheduled for a primary TKA/THA in 18 hospitals in the Netherlands will be assigned to the treat-to-target physio therapy strategy or usual postoperative care. With the treat-to-target strategy a standardized, individually tailored, exercise program is aimed at the attainment of specific functional milestones. Assessments are done at baseline, 6 weeks and 3, 6, 9 and 12 months follow up. The primary outcome will be the Knee injury / Hip disability and Osteoarthritis Outcome Score - Physical Function Short Form (KOOS-PS / HOOS-PS) at 3 months follow up. Secondary outcomes are the numeric rating scale for pain, the Oxford Knee and Hip Scores, performance-based test and the EuroQol 5D-5L for quality of life. Healthcare use, productivity and satisfaction with postoperative care are measured by means of questionnaires. In total, 624 patients will be needed of which 312 TKA and 312 THA patients.

Discussion

The study will provide evidence concerning the (cost-) effectiveness of the treat-to-target postoperative physiotherapy treatment compared to usual postoperative care. The results of this study will address an important evidence gap and will have a significant impact in daily practice of the physio therapist.

Influência da reabilitação física sobre aspectos funcionais em indivíduos submetidos à artroplastia total de quadril: uma revisão sistemática

Resumo Objetivo: Avaliar, por meio de revisão sistemática, a influência do tratamento fisioterapêutico sobre a funcionalidade, amplitude de movimento articular e força muscular em pacientes submetidos à artroplastia total de quadril devido à osteoartrite. Métodos: A busca sistemática de ensaios clínicos randomizados e não randomizados foi conduzida utilizando os bancos de dados eletrônicos PubMed, Web of Science, PEDro, Cochrane, Clinical Trials e SciELO, com base nas estratégias de pesquisa recomendadas pelos itens de relatórios preferenciais para análises sistemáticas e metanálises (PRISMA). Resultados: Em geral, protocolos supervisionados por fisioterapeutas associados à realização de exercícios ativos da musculatura periarticular do quadril e de extensores de joelho têm propiciado importante prognóstico físico e funcional. Exercícios resistidos (dinâmicos e isométricos) de alta intensidade são mais eficazes para a funcionalidade. Para a força muscular e Amplitude de movimento (ADM), exercícios dinâmicos com 3 a 5 séries de 8 a 12 repetições com baixa e alta intensidade promoveram ganhos mais expressivos em relação a outras modalidades terapêuticas. Conclusões: As técnicas e os protocolos utilizados pela fisioterapia para o tratamento da ATQ são variados e possuem importante eficácia clínica comprovada na literatura.

Pragmatic Home-Based Exercise after Total Hip Arthroplasty - Silkeborg: Protocol for a prospective cohort study (PHETHAS-1)

Introduction: Rehabilitation exercises are offered to patients after total hip arthroplasty (THA); however, the effectiveness and optimal type and dose of exercise remains unknown. The primary objective of this trial is to indicate the preliminary efficacy of home-based rehabilitation using elastic band exercise on performance-based function after THA, based on the relationship between the performed exercise dose and the change in performance-based function (gait speed) from 3 (start of intervention) to 10 weeks (end of intervention) after surgery. The secondary objective is to investigate if a dose-response relationship exists between the performed exercise dose and changes in: hip-related disability, lower-extremity functional performance, and hip muscle strength Methods: In this prospective cohort study, patients scheduled for THA will be consecutively included until 88 have completed the intervention period from 3 to 10 weeks postoperatively. Participants perform the standard rehabilitation program with elastic band exercises. Exercise dose (exposure) will be objectively quantified using a sensor attached to the elastic band. The primary outcome is gait speed measured by the 40-m fast-paced walk test. Secondary outcomes include: patient reported hip disability (Hip disability and Osteoarthritis Outcome Score (HOOS)), hip muscle strength (hand-held dynamometry) and lower extremity function (30-s chair stand test). Discussion: This trial will add knowledge concerning the relationship between performed exercise dose and post-operative outcomes after THA. The protocol paper describes the study design and methods in detail, including the statistical analysis plan.

Digital Versus Conventional Rehabilitation After Total Hip Arthroplasty: A Single-Center, Parallel-Group Pilot Study

Background

The demand for total hip arthroplasty (THA) is rising. In the face of rapidly increasing health care costs, ensuring widespread, cost-effective rehabilitation is a priority. Technologies allowing independent home-based rehabilitation may be the key to facilitate access, improve effectiveness, and lower costs of care.

Objective

The aim of this study was to assess the feasibility of a novel artificial intelligence–powered digital biofeedback system following THA and compare the clinical outcomes against supervised conventional rehabilitation.

Methods

This was a single-center, parallel-group pilot study, with an 8-week intervention program. Patients were assessed at baseline, during the program (at 4 and 8 weeks), and 3 and 6 months after surgery. The primary outcome was the Timed Up and Go (TUG) score and secondary outcomes were the Hip dysfunction and Osteoarthritis Outcome Scale (HOOS; a patient-reported outcome) and hip range of motion (ROM).

Results

A total of 66 patients were included: 35 digital physiotherapy (PT) versus 31 conventional. There were no differences at baseline between groups except for lower HOOS quality of life (QoL) subscale scores in the digital PT group. Clinically relevant improvements were noted in both groups at all time points. The digital PT group showed a retention rate of 86% (30/35). Per-protocol analysis revealed a superiority of the digital PT group for all outcome measures. Intention-to-treat analysis revealed the superiority of the digital PT group at all time points for TUG (change between baseline and 4 and 8 weeks: P<.001; change between baseline and 3 and 6 months: P=.001 and P=.005, respectively), with a difference between median changes of −4.79 seconds (95% CI −7.24 to −1.71) at 6 months post-THA. Between baseline and month 6, results were also superior in the digital PT group for the HOOS sports and QoL subscales and all ROM except for standing flexion.

Conclusions

This study demonstrates this novel solution holds promise in rehabilitation after THA, ensuring better clinical outcomes than conventional rehabilitation while reducing dependence on human resources.

Variation in rehabilitation setting after uncomplicated total knee or hip arthroplasty: a call for evidence-based guidelines

Background

High-level evidence consistently indicates that resource-intensive facility-based rehabilitation does not provide better recovery compared to home programs for uncomplicated knee or hip arthroplasty patients and, therefore, could be reserved for those most impaired. This study aimed to determine if rehabilitation setting aligns with evidence regardless of insurance status.

Methods

Sub-study within a national, prospective study involving 19 Australian high-volume public and private arthroplasty centres. Individuals undergoing primary arthroplasty for osteoarthritis participated. The main outcome was the proportion participating in each rehabilitation setting, obtained via chart review and participant telephone follow-up at 35 and 90 days post-surgery, categorised as ‘facility-based’ (inpatient rehabilitation and/or ≥ four outpatient-based sessions, including day-hospital) or ‘home-based’ (domiciliary, monitored or unmonitored home program only). We compared characteristics of the study cohort and rehabilitation setting by insurance status (public or private) using parametric and non-parametric tests, analysing the knee and hip cohorts separately.

Results

After excluding ineligible participants (bilateral surgeries, self-funded insurance, participation in a concurrent rehabilitation trial, experience of a major acute complication potentially affecting their rehabilitation pathway), 1334 eligible participants remained. Complete data were available for 1302 (97%) [Knee: n = 610, mean age 68.7 (8.5) yr., 51.1% female; Hip: n = 692, mean age 65.5 (10.4) yr., 48.9% female]; 26% (158/610) of knee and 61% (423/692) of hip participants participated predominantly in home-based programs. A greater proportion of public recipients were obese and had greater pre-operative joint impairment, but participated more commonly in home programs [(Knee: 32.9% (79/240) vs 21.4% (79/370) (P = 0.001); Hip: 71.0% (176/248) vs 55.6% (247/444) (P <  0.001)], less commonly in inpatient rehabilitation [Knee: 7.5% (18/240) vs 56.0% (207/370) P (< 0.001); Hip: 4.4% (11/248) vs 33.1% (147/444) (P <  0.001], and had fewer outpatient treatments [Knee: median (IQR) 6 (3) vs 8 (6) (P < 0.001); Hip: 6 (4) vs 8 (6) (P < 0.001)].

Conclusions

Facility-based programs remain the norm for most knee and many hip arthroplasty recipients with insurance status being a major determinant of care. Development and implementation of evidence-based guidelines may help resolve the evidence-practice gap, addressing unwarranted practice variation across the insurance sectors.

Web-Based, Self-Directed Physical Therapy After Total Hip Arthroplasty Is Safe and Effective for Most, but Not All, Patients

BACKGROUND

Recent data suggested that unsupervised, self-directed physical therapy (SDPT) is both safe and efficacious for patients undergoing total hip arthroplasty (THA) and that formal outpatient physical therapy (OPPT) may not be routinely required. The purpose of this study was to evaluate the routine use of an SDPT program in a nonselect patient population.

METHODS

This is a multi-surgeon, single-institution, retrospective study of 941 consecutive patients discharged home, from January 2016 to December 2016, after primary, unilateral THA and enrolled in a web-based SDPT program. Patients were seen 4 weeks after surgery and OPPT was prescribed for perceived need, patient request, or if unable to use the web-based program. Patient-reported outcomes, medical comorbidities, and assessment of home environment were prospectively recorded.

RESULTS

Overall, 646 of 941 patients (68.7%) were not prescribed OPPT (SDPT-only group) while 295 of 941 patients (31.3%) were prescribed OPPT (SDPT + OPPT group). In the SDPT + OPPT group, 88.2% were for perceived need, 10.8% for patient request, and 1.0% due to inability to use the web-based platform. Multivariate analysis identified male sex (odds ratio, 0.64; 0.45-0.90; P = .012) and a higher preoperative Short Form-12 physical component (odds ratio, 0.98; 0.96-0.99; P = .036) as independent variables protective against requiring OPPT. At a minimum 6-month follow-up, the SDPT-only group had statistically higher hip disability and osteoarthritis outcome score junior compared to the SDPT + OPPT cohort (85.0 vs 80.9; P = .012).

CONCLUSION

Web-based SDPT is safe and effective for most, but not all, patients eligible for home discharge after THA. It is critical to preserve OPPT services for the one-third of patients who require them.

Efficacy of exercise for improving functional outcomes for patients undergoing total hip arthroplasty: A meta-analysis

BACKGROUND

The objective of this meta-analysis was aimed to illustrate the functional outcomes of exercise for total hip arthroplasty (THA) patients.

METHODS

In July, 2018, a systematic computer-based search was conducted in PubMed, EMBASE, Web of Science, Cochrane Database of Systematic Reviews, and Google database. Data on exercise for functional outcomes for THA patients were retrieved. The primary endpoint was walking speed. Other outcomes included physical activity scale, Harris hip score, pain scores, abduction strength, and the length of hospital stay. After testing for publication bias and heterogeneity between studies, data were aggregated for random-effects models when necessary.

RESULTS

Ten clinical studies with 441 patients were ultimately included in the meta-analysis. Compared with the control group, exercise was associated with an increase of the walking speed by 0.15 m/s than control group (weighted mean difference [WMD] 0.15; 95% confidence interval [CI] 0.08, 0.22; P = .000). Also, exercise group could also increase Harris hip score (WMD 8.49; 95% CI 5.19, 11.78; P = .000) and abduction strength than control group (WMD 9.75; 95% CI 5.33, 14.17; P = .000). What is more, exercise has a beneficial role in reducing the pain scores (WMD -1.32; 95% CI -2.07, -0.57; P = .001) and the length of hospital stay (WMD -0.68; 95% CI -1.07, -0.29; P = .001) than the control group. However, there was no significant difference between the physical activity scale (WMD -2.13; 95% CI -6.31, 2.05; P = .317).

CONCLUSIONS

Compared with control group in the management of THA, postoperative exercise has a better pain relief and clinical outcomes. Considering the beneficial of the postoperative exercise, we take a positive attitude toward use exercise for patients with THA.

Rehabilitation strategies for optimisation of functional recovery after major joint replacement

Exercise-based interventions applied before and after total hip and knee arthroplasty (THA and TKA, respectively) have been investigated for a number of years, based on the assumption that they will enhance post-operative recovery. Although recent studies suggest that high-volume, pre-operative exercise may enhance post-operative recovery after TKA, studies of post-operative exercise-based interventions, have not found superiority of one exercise regime over another. It seems, however, that post-operative, exercise-based, rehabilitation is superior to no or minimal rehabilitation after THA and TKA.The goal of this commentary is to summarize recent evidence for the efficacy of different peri-operative exercise-based interventions to enhance recovery after THA and TKA, and to propose new strategies to further enhance post-operative recovery.There is a major need to improve functional recovery after THA and TKA. We propose a strategy of "enriched" trials where specific rehabilitation interventions are applied to different patients based on, for example, their expectations for post-operative recovery, willingness to undertake exercise and physical activity, and pre-operative functional performance.

Effects of supervised exercise compared to non-supervised exercise early after total hip replacement on patient-reported function, pain, health-related quality of life and performance-based function – a systematic review and meta-analysis of randomized controlled trials

Background:

The rehabilitation after a total hip replacement varies in degree of supervision; however, it remains unknown whether supervised programmes are more effective than non-supervised.

Objective:

This study compared the effectiveness of supervised exercise compared to non-supervised home-based exercise after total hip replacement on patient-reported function, hip-pain, health-related quality of life and performance-based function.

Methods:

A systematic review and meta-analysis of randomized controlled trials investigating the effect of supervised exercise compared to non-supervised home-based exercise. An electronic search was performed in Medline, Embase and CINAHL on 14 March 2018. The methodological quality was assessed using the Cochrane Risk of Bias tool.

Results:

Seven studies were included with a total of 389 participants. A small and non-significant difference in favour of the supervised groups was found in patient-reported function (standardized mean difference (SMD) −0.22 (95% confidence interval (CI) −0.46 to 0.02)), hip-related pain (SMD −0.03 (95% CI −0.27 to 0.21)), health-related quality of life (mean difference (MD) −3.08 (95% CI −6.29 to 0.14)) and performance-based function (SMD −0.26 (95% CI −0.68 to 0.17)) at end of treatment and in patient-reported function (MD −1.31 (95% CI −3.79 to 1.16)) at the 6- to 12-month follow-up.

Limitations:

The literature search was systematic, but limited to three databases. The overall quality of evidence was downgraded to moderate due to lack of blinding in included studies.

Conclusion:

Supervised exercise was not significantly effective compared to non-supervised home-based exercise on patient-reported function, pain, health-related quality of life and performance-based function after primary total hip replacement.

A randomized controlled trial on maximal strength training in 60 patients undergoing total hip arthroplasty

Background and purpose - Total hip arthroplasty (THA) patients have reduced muscle strength after rehabilitation. In a previous efficacy trial, 4 weeks' early supervised maximal strength training (MST) increased muscle strength in unilateral THA patients <65 years. We have now evaluated muscle strength in an MST and in a conventional physiotherapy (CP) group after rehabilitation in regular clinical practice. Patients and methods - 60 primary THA patients were randomized to MST or CP between August 2015 and February 2016. The MST group trained at 85-90% of their maximal capacity in leg press and abduction of the operated leg (4 × 5 repetitions), 3 times a week at a municipal physiotherapy institute up to 3 months postoperatively. The CP group followed a training program designed by their respective physiotherapist, mainly exercises performed with low or no external loads. Patients were tested pre- 3, 6, and 12 months postoperatively. Primary outcomes were abduction and leg press strength at 3 months. Other parameters evaluated were pain, 6-min walk test, Harris Hip Score (HHS) and Hip disability and Osteoarthritis Outcome Score (HOOS) Physical Function Short-form score. Results - 27 patients in each group completed the intervention. MST patients were substantially stronger in leg press and abduction than CP patients 3 (43 kg and 3 kg respectively) and 6 months (30 kg and 3 kg respectively) postoperatively (p ≤ 0.002). 1 year postoperatively, no intergroup differences were found. No other statistically significant intergroup differences were found. Interpretation - MST increases muscle strength more than CP in THA patients up to 6 months postoperatively, after 3 months' rehabilitation in clinical practice. It was well tolerated by the THA patients and seems feasible to conduct within regular clinical practice.

The determination of the validity of an application-based knee-training device

The goals of knee rehabilitation are to improve range of motion and muscle status. The aim of the study was to investigate accuracy and reproducibility of a newly designed knee-training device (KT) under standardized laboratory conditions.Two application-based software programs, one to measure maximum force and the other intended to improve users' coordination were developed to be used on a tablet during exercises, wirelessly connected to KT placed under the popliteal fossa.KT was loaded for 20 intervals of 15 seconds (s) ranging between 0-350 Newton (N) each. The interval of times was chosen to be enough to take right measurement for accurate results. In addition, a 300-s continuous measurement was undertaken. The pressure readings were developed through a servo-hydraulic system and used as reference values. KT results were compared with the reference values to assess its accuracy. In addition, KT was tested on a force-measuring platform in a close to reality measurement.Based on Bland-Altman plots, the mean difference between KT and material testing machine was -0.63 N (0.4%), between KT and force-measuring platform was -0.11 N (0.7%), which proves the accuracy of its result.Laboratory experiments confirm that KT delivers precise and reproducible values, which provide base for clinical trials.

Good function and high patient satisfaction at mean 2.8 years after dual mobility THA following femoral neck fracture: a cross-sectional study of 124 patients

Aims

Our aim was to investigate function, health status and satisfaction in patients treated with primary dual mobility (DM) total hip arthroplasty (THA) after displaced femoral neck fracture (FNF).

Patients and methods

From 2005-2011, 414 consecutive FNF patients received Saturne DM THA. At a minimum of 1-year follow-up, 124 (95 women) were evaluated with Oxford Hip Score (OHS), Harris Hip Score (HHS), health-related quality of life (HRQoL) measure (EQ-5D) and two functional tests: Timed Up and Go (TUG) and Sit to Stand 10 times (STS). The FNF patients were matched 1:2 by age, sex and surgery date with patients receiving THA due to osteoarthrosis (OA group) and 1-year OHS and EQ5D were compared. FNF patients were matched by age and sex with the general population index (GPI) for EQ-5D comparison.

Results

Patient age at surgery after FNF was mean 74.8 (range 30-92) years. At mean follow-up of 2.8 (range 1.0-7.7) years, mean EQ-5D score was 0.79 (SD 0.15) in the FNF group, which was similar to the matched GPI (p = 0.4), but lower (p = 0.014) compared to the OA group. Mean OHS was 36.4 (SD 9.5) in the FNF group and 38.4 (SD 7.2) in the OA group (p = 0.18). HHS in the FNF group was 78.7 (SD 15.5). Mean TUG time was 13.5 (SD 4.9) secs, and mean STS was 37.9 (SD 15.3) secs. Eighty nine percent (n = 111) of FNF patients were satisfied with the operation result.

Conclusion

DM THA following displaced FNF provides a good functional result and quality of life in addition to high patient satisfaction.

The therapeutic validity and effectiveness of physiotherapeutic exercise following total hip arthroplasty for osteoarthritis: A systematic review

Objective

To assess the therapeutic validity and effectiveness of physiotherapeutic exercise interventions following total hip arthroplasty (THA) for osteoarthritis.

Data sources

The databases Embase, MEDLINE, Cochrane Library, CINAHL and AMED were searched from inception up to February 2017.

Eligibility criteria

Articles reporting results of randomized controlled trials in which physiotherapeutic exercise was compared with usual care or with a different type of physiotherapeutic exercise were included, with the applied interventions starting within six months after THA. Only articles written in English, German or Dutch were included.

Study appraisal

Therapeutic validity (using the CONTENT scale) and risk of bias (using both the PEDro scale and the Cochrane Collaboration’s tool) were assessed by two researchers independently. Characteristics of the physiotherapeutic exercise interventions and results about joint and muscle function, functional performance and self-reported outcomes were extracted.

Results

Of the 1124 unique records retrieved, twenty articles were included. Only one article was considered to be of high therapeutic validity. Description and adequacy of patient selection were the least reported items. The majority of the articles was considered as having potentially high risk of bias, according to both assessment tools. The level of therapeutic validity did not correspond with the risk of bias scores. Because of the wide variety in characteristics of the physiotherapeutic exercise and control interventions, follow-up length and outcome measures, limited evidence was found on the effectiveness of physiotherapeutic exercise following THA.

Conclusion

The insufficient therapeutic validity and potentially high risk of bias in studies involving physiotherapeutic exercise interventions limit the ability to assess the effectiveness of these interventions following THA. Researchers are advised to take both quality scores into account when developing and reporting studies involving physiotherapeutic exercise. Uniformity in intervention characteristics and outcome measures is necessary to enhance the comparability of clinical outcomes between trials.

Fast track in hip arthroplasty

‘Fast-track’ surgery was introduced more than 20 years ago and may be defined as a co-ordinated peri-operative approach aimed at reducing surgical stress and facilitating post-operative recovery.

The fast-track programmes have now been introduced into total hip arthroplasty (THA) surgery with reduction in post-operative length of stay, shorter convalescence and rapid functional recovery without increased morbidity and mortality. This has been achieved by focusing on a multidisciplinary collaboration and establishing ‘fast-track’ units, with a well-defined organisational set-up tailored to deliver an accelerated peri-operative course of fast-track surgical THA procedures.

Fast-track THA surgery now works extremely well in the standard THA patient. However, all patients are different and fine-tuning of the multiple areas in fast-track pathways to get patients with special needs or high co-morbidity burden through a safe and effective fast-track THA pathway is important.

In this narrative review, the principles of fast-track THA surgery are presented together with the present status of implementation and perspectives for further improvements.

Formal Physical Therapy After Total Hip Arthroplasty Is Not Required: A Randomized Controlled Trial

BACKGROUND

The value of formal physical therapy after total hip arthroplasty is unknown. With substantial changes that have occurred in surgical and anesthesia techniques, self-directed therapy may be efficacious in restoring function to patients undergoing total hip arthroplasty.

METHODS

We conducted a single-center, randomized trial of 120 patients undergoing primary, unilateral total hip arthroplasty who were eligible for direct home discharge. The experimental group followed a self-directed home exercise program for 10 weeks. The control group received the standard protocol for physical therapy that included in-home visits with a physical therapist for the first 2 weeks followed by formal outpatient physical therapy for 8 weeks. Functional outcomes were measured using validated instruments including the Harris hip score (HHS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Short Form-36 Health Survey (SF-36) preoperatively, at 1 month postoperatively, and at 6 to 12 months postoperatively.

RESULTS

Of 120 randomized patients, 108 were included in the final analysis. Ten patients (19%) were randomized to unsupervised home exercise and 20 patients (37%) were randomized to formal outpatient therapy crossed over between groups. There was no significant difference in any of the measured functional outcomes between patients receiving formal therapy (n = 54) and those participating in unsupervised home exercise (n = 54) at any time point (HHS, p = 0.82; WOMAC, p = 0.80; and SF-36 physical health, p = 0.90).

CONCLUSIONS

This randomized trial suggests that unsupervised home exercise is both safe and efficacious for a majority of patients undergoing total hip arthroplasty, and formal physical therapy may not be required.

Rehabilitation after total joint replacement: a scoping study

PURPOSE

The evidence supporting rehabilitation after joint replacement, while vast, is of variable quality making it difficult for clinicians to apply the best evidence to their practice. We aimed to map key issues for rehabilitation following joint replacement, highlighting potential avenues for new research.

MATERIALS AND METHODS

We conducted a scoping study including research published between January 2013 and December 2016, evaluating effectiveness of rehabilitation following hip and knee total joint replacement. We reviewed this work in the context of outcomes described from previously published research.

RESULTS

Thirty individual studies and seven systematic reviews were included, with most research examining the effectiveness of physiotherapy-based exercise rehabilitation after total knee replacement using randomized control trial methods. Rehabilitation after hip and knee replacement whether carried out at the clinic or monitored at home, appears beneficial but type, intensity and duration of interventions were not consistently associated with outcomes. The burden of comorbidities rather than specific rehabilitation approach may better predict rehabilitation outcome. Monitoring of recovery and therapeutic attention appear important but little is known about optimal levels and methods required to maximize outcomes.

CONCLUSIONS

More work exploring the role of comorbidities and key components of therapeutic attention and the therapy relationship, using a wider range of study methods may help to advance the field. Implications for Rehabilitation Physiotherapy-based exercise rehabilitation after total hip replacement and total knee replacement, whether carried out at the clinic or monitored at home, appears beneficial. Type, intensity, and duration of interventions do not appear consistently associated with outcomes. Monitoring a patient's recovery appears to be an important component. The available research provides limited guidance regarding optimal levels of monitoring needed to achieve gains following hip and knee replacement and more work is required to clarify these aspects. The burden of comorbidities appears to better predict outcomes regardless of rehabilitation approach.

Rehabilitation of revision total hip replacement: A multi-centre survey of current practice

BACKGROUND

Demand for revision total hip replacement (RTHR) is increasing. Outcomes after RTHR are varied, with reasonable pain relief but smaller gains in function and mobility. Whether sub-optimal rehabilitation contributes to poorer functional outcomes is unclear. Current rehabilitation is not well defined and there is little research into RTHR rehabilitation.

AIMS AND OBJECTIVES

To gather information about the current rehabilitation of patients undergoing planned, single-stage revision or re-revision THR surgery.

METHODS

An online survey was developed and sent to clinicians at 117 orthopaedic centres in England, Wales and Northern Ireland. Questions were asked about standard rehabilitation practice pre-operatively, post-operatively and immediately after discharge. The frequency (%) of responses to closed questions was analysed and free-text comments were summarized thematically.

RESULTS

There were 133 respondents: mostly physiotherapists (92, 69%) and occupational therapists (39, 29%). Pre-operative education was common (112, 84%) but not uniform, and for 52 (46%) the same as for primary THR patients. Respondents were more likely to agree about the general objectives of rehabilitation, for example gait re-education with walking aids (93, 70%), and retraining functional mobility (92, 69%) rather than about specific elements including exercise prescription, duration of hip precautions and provision of occupational therapy. The provision of rehabilitation following discharge varied considerably.

CONCLUSIONS

This survey adds to sparse information about rehabilitation RTHR. No consensus emerged about optimal rehabilitation. The diversity in approach and lack of clear structure suggests work is needed to develop rehabilitation interventions that are tailored to this population.

Description of load progression and pain response during progressive resistance training early after total hip arthroplasty: secondary analyses from a randomized controlled trial

Objective:

To describe a progressive resistance training intervention implemented shortly after total hip arthroplasty, including a detailed description of load progression, pain response and adverse events to the training.

Design:

Secondary analyses of data from the intervention group in a randomized controlled trial.

Subjects:

This study reports data from the intervention group ( n = 37).

Interventions:

The protocol described supervised progressive resistance training of the operated leg two days/week in addition to home-based exercise five days/week and for 10 weeks. The relative load progressed from 12 repetition maximum to 8 repetition maximum during 10 weeks for the exercises: knee extension, hip abduction, -flexion and -extension.

Main measures:

Training load in kilograms (kg) for each exercise, hip pain during, before and after exercise using the Visual Analog Scale and adverse events during the initial four weeks of training.

Results:

The majority of patients experienced only moderate hip pain during exercise (range in median across exercises and sessions: 5–35 mm Visual Analog Scale) and mild pain at rest (median: 1–18 mm Visual Analog Scale), both of which decreased over time ( p < 0.001), despite a substantial increase in absolute training load (67%–166 % across exercises, p < 0.001). Out of 152 training sessions, short term pain response (an increase >20 mm Visual Analog Scale) occurred in 13 patients in 24 training sessions.

Conclusion:

Progressive resistance training as described in the present study can be implemented shortly following total hip arthroplasty with substantial load progression and no overall exacerbation of postoperative pain. Some patients may experience a short term pain response.

Improvement of walking speed and gait symmetry in older patients after hip arthroplasty: a prospective cohort study

Background

Retraining walking in patients after hip or knee arthroplasty is an important component of rehabilitation especially in older persons whose social interactions are influenced by their level of mobility. The objective of this study was to test the effect of an intensive inpatient rehabilitation program on walking speed and gait symmetry in patients after hip arthroplasty (THA) using inertial sensor technology.

Methods

Twenty-nine patients undergoing a 4-week inpatient rehabilitation program following THA and 30 age-matched healthy subjects participated in this study. Walking speed and gait symmetry parameters were measured using inertial sensor device for standardized walking trials (2*20.3 m in a gym) at their self-selected normal and fast walking speeds on postoperative days 15, 21, and 27 in patients and in a single session in control subjects. Walking speed was measured using timing lights. Gait symmetry was determined using autocorrelation calculation of the cranio-caudal (CC) acceleration signals from an inertial sensor placed at the lower spine.

Results

Walking speed and gait symmetry improved from postoperative days 15–27 (speed, female: 3.2 and 4.5 m/s; male: 4.2 and 5.2 m/s; autocorrelation, female: 0.77 and 0.81; male: 0.70 and 0.79; P <0.001 for all). After the 4-week rehabilitation program, walking speed and gait symmetry were still lower than those in control subjects (speed, female 4.5 m/s vs. 5.7 m/s; male: 5.2 m/s vs. 5.3 m/s; autocorrelation, female: 0.81 vs. 0.88; male: 0.79 vs. 0.90; P <0.001 for all).

Conclusions

While patients with THA improved their walking capacity during a 4-week inpatient rehabilitation program, subsequent intensive gait training is warranted for achieving normal gait symmetry. Inertial sensor technology may be a useful tool for evaluating the rehabilitation process during the post-inpatient period.
