Prehabilitation Improves Knee Functioning Before and Within the First Year After Total Knee Arthroplasty: A Systematic Review With Meta-analysis

Feasibility of prehabilitation for patients awaiting total knee arthroplasty; a pilot study

Objective

To examine the feasibility of conducting a preoperative home-based prehabilitation program for total knee arthroplasty patients at risk for delayed in-hospital recovery, and to explore the pre- and postoperative impact of this program.

Design

A retrospective cohort study with matched controls, enabling subgroup analyses.

Setting

Home-based.

Subjects

Patients awaiting primary unilateral total knee arthroplasty between 2019 and 2020, were compared with matched historic cases from 2016 to 2017. Matching criteria were scoring ≤17 points on the De Morton Mobility Index and >12.5 s on the timed-up-and-go test.

Intervention

Supervised home-based prehabilitation program versus no prehabilitation.

Outcomes

Feasibility, determined by recruitment rate, adherence, and safety of the program. Preoperative impact, assessed for the intervention group by differences in mean values for aerobic capacity, muscle strength and functional mobility between the first and last sessions. Postoperative impact was defined as the time needed to achieve in-hospital independence of physical function and was measured by the differences in mean values between the intervention and control groups.

Results

Recruitment rate was 71 %; adherence and drop-out rates were 88 % and 12 % respectively. No adverse events were reported. Preoperatively, the intervention group showed significant improvements in aerobic capacity on the 2-min walking test (84.29 m-98.06 m; p = 0.007) and 2-min step test (40.35 steps to 52.95 steps; p = 0.014), muscle strength on the 30 s chair stand test (7.3 stands to 10.1 stands; p = 0.002), and functional mobility as seen in the timed-up-and-go-test (19.52 s-15.85 s; p = 0.031). Postoperatively, the intervention group achieved in-hospital independence of physical function earlier (mean rank 16.11) than the control group (mean rank 24.89; p=<0.01).

Conclusions

It is feasible to conduct a prehabilitation program 4-6 weeks preoperatively, for high-risk patients awaiting total knee arthroplasty. Additionally, the program appears to have a positive impact on physical fitness both pre- and postoperatively.

[Blood flow restriction training (BFRT) in patients before and after total knee arthroplasty]

BACKGROUND

In healthy individuals, blood flow restriction training (BFRT) has shown positive effects on muscle mass, strength, fatigue resistance, as well as tendon and bone metabolism. BFRT reduces blood flow in the extremities using inflatable cuffs, creating local muscular hypoxia, which produces an anabolic metabolic environment. This promotes significant muscular and cardiovascular adaptations even at low mechanical training loads.

KNEE ENDOPROSTHESES

BFRT also shows promising initial results in pre- and postoperative applications for knee endoprostheses (KTEP). Both preoperative and postoperative BFRT can improve muscle strength and joint function, accelerate recovery, and alleviate pain. Although the method is generally safe, potential risks such as discomfort and rare side effects must be considered. Clear application protocols are still lacking, necessitating further research and individualized programs to achieve optimal training effects. BFRT thus offers an innovative way to effectively rehabilitate patients despite their low load tolerance.

The Effect of Blood Flow Restriction Exercise Prior to Total Knee Arthroplasty on Postoperative Physical Function, Lower Limb Strength and Patient-Reported Outcomes: A Randomized Controlled Trial

The trial aimed to examine the effect of eight weeks preoperative low-load blood flow restricted resistance training (BFR-RT) on physical function, lower limb strength, and patient-reported outcomes in knee OA patients 3 and 12 months after total knee arthroplasty (TKA) compared with preoperative usual care. An assessor blinded randomized controlled trial (RCT) was conducted. Eighty-six patients scheduled for TKA who were allocated to 8 weeks BFR-RT on the affected leg 3x/week or preoperative usual care involving no exercise (CON).

PRIMARY OUTCOME

30-s sit to stand (30STS).

SECONDARY OUTCOMES

Timed Up&Go, 40-m walk test (40mWT), knee range of motion (ROM) 1-repetition maximum (1RM) leg press and knee extensor strength, maximal isometric contraction (MVIC) for the knee extensors and flexors, Knee injury and Osteoarthritis Outcome Score (KOOS), and Euroqol 5-dimensions (EQ-5D-L5) questionnaire. Data were collected at baseline (12 weeks pre-surgery), ~3 days pre-surgery, 3 and 12 months postoperatively. Intention-to-treat analysis revealed no significant between-group differences in the change from baseline to 3 and 12 months postoperatively on 30STS, TUG, or 40mFWT. Significant between-group differences were observed at 3 but not 12 months postoperatively for the corresponding changes in 1RM leg press strength, 1RM knee extensor strength, and MVIC knee extensor favoring BFR-RT. No between-group differences were observed for the delta changes from baseline in knee ROM, KOOS subscales or EQ-5D-L5 at any postoperative time points. These findings suggest that preoperative BFR-RT offered no superior effects compared with usual preoperative care on postoperative physical function or patient-reported outcomes. Preoperative BFR-RT produced amplified gains in lower limb muscle strength at 3 months postoperatively.

Navigating the Global Landscape of Exercise Interventions for Knee Osteoarthritis: Exploring Evolving Trends and Emerging Frontiers From a Bibliometric and Visualization Analysis Perspective (2011-2022)

OBJECTIVES

This study utilizes visual analysis methods to retrospectively examine the evolution and trends in exercise interventions for knee osteoarthritis (KOA) research from 2011 to 2022.

DESIGN

Bibliometric and visualization analysis review.

SETTING AND PARTICIPANTS

Using the Web of Science database, the literature search range is from January 1, 2011, to December 31, 2022, with the language specified as English and document type set to Article.

METHODS

Visual analysis was used to analyze literature in the field of exercise interventions for KOA, with KOA and exercise interventions as the key search terms. Visualization maps for countries/regions were created using Tableau and Scimago Graphica software. Institutional, author, and keyword visualization maps were drawn using CiteSpace and VOSviewer software.

RESULTS

In total, 3137 articles were included in the visual analysis. The United States emerged as the leading country in terms of publication volume and contribution. Moreover, developed countries such as the United States, Australia, United Kingdom, and Canada have established close and stable cooperative relationships. The University of Melbourne stood out as the institution with both the highest publication volume and centrality. At the forefront of research output in this field was Bennell K.L. from the University of Melbourne. The journal with the highest co-citation frequency was Osteoarthritis and Cartilage. The keyword clustering map highlighted an evolution in the field of exercise interventions for KOA, emphasizing 8 key research themes spanning knee osteoarthritis, serum cartilage, osteoarthritis initiative, patellofemoral pain, total knee arthroplasty, exercise-induced hypoalgesia, isometric exercise, and anterior cruciate ligament reconstruction. Burst analysis revealed that older adult was the earliest and most prominent keyword, with contemporary topics such as patellofemoral pain, safety, musculoskeletal disorder, and neuromuscular exercise considered as research hotspots and future directions in this field.

CONCLUSIONS AND IMPLICATIONS

The global attention on exercise interventions for KOA research is expanding, emphasizing the importance of strengthened connections among developing countries and collaborative author groups. Recent trends have shifted toward topics such as neuromuscular training, treatment safety, and musculoskeletal disorders, whereas research interest in patellofemoral pain remains unabated. Neuromuscular training for KOA represents the current frontier in this field. Future research should delve into the effects of diverse types of exercise interventions for KOA on neuromuscular injury and recovery, exploring feasibility and safety to formulate personalized exercise plans for patients with KOA.

Associations Between Prehabilitation and Postoperative Healthcare Utilization for Total Hip or Total Knee Arthroplasty in Medicare Beneficiaries

BACKGROUND

Prehabilitation has potential to improve outcomes in value-based care models. We examined the associations between the receipt of prehabilitation (physical therapy [PT] services within 30 days preoperatively) and postoperative healthcare utilization in a national cohort of fee-for-service Medicare beneficiaries.

METHODS

This retrospective cohort study used the 5% fee-for-service claims from the Medicare limited data set to identify unilateral elective inpatient total hip arthroplasty (THA) procedures (n = 25,509) and total knee arthroplasty (TKA) procedures (n = 40,091) from January 1, 2016 to September 30, 2021. Associations between prehabilitation and postoperative healthcare utilization were analyzed in mixed-effects generalized linear models adjusting for patient-level and hospital-level factors. We report adjusted odds ratios (OR) or % differences.

RESULTS

Prehabilitation (13.1% THA, 13.1% TKA) was not significantly associated with institutional postacute care discharge, 30-day emergency department visits, or 90-day readmissions. For TKA, prehabilitation was significantly associated with decreased odds of an extended hospital length of stay (OR = 0.86, P = 0.02) and reduced length of stay in an institutional postacute care facility (-5.71%, P = 0.004). In both THA and TKA, prehabilitation was associated with decreased use of 90-day home health physical and/or occupational therapy (THA: OR = 0.82, P = 0.001; TKA: OR = 0.67, P < 0.001). In contrast, prehabilitation in both cohorts was associated with the increased odds of receiving any 90-day outpatient PT (THA: OR = 2.08, P < 0.001; TKA: OR = 2.48, P < 0.001) and an increased number of 90-day outpatient PT visits (THA: +4.04%, P = 0.01; TKA: +5.21%, P < 0.001).

CONCLUSION

Prehabilitation was associated with some decreases in postoperative healthcare utilization, particularly for TKA. Associations of preoperative PT with increased postoperative outpatient PT may reflect variation in referral patterns or patient access. These results highlight the importance of continued research into the impact of prehabilitation on healthcare utilization, patient outcomes, and episode costs. Additionally, further research should identify which patients would benefit the most from prehabilitation to increase the value of care.

Effect of prehabilitation for patients undergoing gastric cancer surgery: a protocol of a systematic review and meta-analysis

INTRODUCTION

Gastric cancer is a high-risk cancer with surgical treatments often leading to significant postoperative complications and mortality. Prehabilitation, involving exercise, nutrition and psychological support before surgery, aims to boost patients' physical and mental health. While effective in other cancers, its benefits for gastric cancer need further study. This research will evaluate the impact of trimodal prehabilitation on patient outcomes in gastric cancer surgery, aiming to reduce complications and expedite recovery.

METHODS AND ANALYSIS

This study will systematically review randomised controlled trials and cohort studies evaluating the role of prehabilitation in people undergoing gastric cancer resection. The primary outcomes of interest will include overall postoperative complications and length of hospital stay. The secondary outcomes of interest will include mortality, readmission rate or functional recovery. Databases including PubMed, EMBASE, CINAHL, CENTRAL, Chinese BioMedical Literature Database (CBM), Chinese National Knowledge Infrastructure (CNKI), Wanfang database and Chinese Science and Technology Periodicals (VIP) will be searched. All studies will be screened and selected using the criteria described in 'population, intervention/exposure, comparison, outcome and study design' format. Two independent reviewers will screen studies for relevance and methodological validity. Data from included studies will be extracted through a customised, preset data extraction sheet. The Cochrane Review Manager (V.5.3, Nordic Cochrane Centre, Copenhagen, Denmark) software will be used to perform the meta-analysis.

ETHICS AND DISSEMINATION

Ethics approval is not required for this study as all results will be based on published papers. No primary data collection will be needed. Study findings will be presented at scientific conferences or published in a peer-reviewed scientific journal.

Preoperative lifestyle modifications combined with a structured exercise protocol on patient outcomes following total knee replacement surgery: A systematic review

BACKGROUND

Medical guidelines recommend structured prehabilitation protocols consisting of lifestyle modifications and exercise to enhance post-operative outcomes for patients undergoing a total knee replacement (TKR). However, current research showing effectiveness is limited and has primarily focused on outcomes of exercise-based prehabilitation.

OBJECTIVES

To investigate whether a structured prehabilitation protocol consisting of exercise and lifestyle modifications improves physical function and patient-reported outcomes following TKR surgery compared with usual care.

DESIGN

Systematic review.

METHODS

Five databases were searched to identify randomised controlled trials comparing structured prehabilitation programs consisting of lifestyle modifications and exercise, with usual care, for those undergoing a TKR. Methodological quality of included studies was assessed via the RoB 2.0 tool and results synthesis via a Grading of Recommendation Assessment, Development and Evaluation approach was performed to determine the certainty evidence for each outcome.

RESULTS/FINDINGS

Four studies were included in this review. Despite a positive trend supporting the inclusion of a structured prehabilitation protocol, additional improvements in post-operative pain, physical function and self-reported function were only seen in one study. Reductions in hospital length of stay were also seen in one study. No additional improvements in post-operative quality of life following prehabilitation were reported.

CONCLUSION

Limited evidence supporting prehabilitation reported in our review is likely attributed to the intervention type, intensity, and delivery model of included studies. However, there remains to be strong evidence supporting the use of a structured prehabilitation protocol consisting of lifestyle modifications and exercise to improve post-operative outcome.

Satisfactory adherence to the Dutch physical therapy guideline for patients with a total knee arthroplasty. A survey study involving 103 specialised physical therapists

OBJECTIVE

To explore and gain more insight into the usual preoperative and postoperative physical therapy (PT) treatment of patients with a total knee arthroplasty (TKA) among Dutch physical therapists experienced with TKA rehabilitation. Secondly, to evaluate physical therapists' adherence to guideline recommendations for postoperative rehabilitation.

METHODS

In this cross-sectional study, physical therapists working in primary care within a designated Dutch hospital's catchment area were surveyed online. The survey queried PT treatment approaches before surgery, during hospitalisation, and after surgery. All data were analysed descriptively. When both education and all recommended exercise modalities were used postoperatively, therapists were considered fully adherent with the Dutch clinical practice guideline.

RESULTS

One hundred and three therapists participated, representing a response rate of 58%. Postoperative PT treatment was applied by all therapists, of which 65 (63.1%) were fully adherent to the guideline. Partial adherence was mainly due to not using the aerobic exercise modality. Furthermore, beyond the modalities recommended in the guideline, a range of PT interventions were used. Preoperative treatment was applied by 73 therapists (70.9%). These 73 indicated that only a median of 20% (IQR 10%-40%) of their patients received preoperative PT.

CONCLUSIONS

This study revealed satisfactory adherence to guideline recommendations on postoperative management of patients with a TKA among experienced physical therapists. Aerobic exercises were utilised less often or with inappropriate intensity. Correct adherence to guideline recommendations on aerobic exercise training can result in more physically active individuals and important general health benefits.

Implementation of Physical Therapist Services for Men Undergoing Radical Prostatectomy: An Administrative Case Report

OBJECTIVE

Prostate cancer is the most commonly diagnosed cancer among men in the USA, and radical prostatectomy (RP) is the primary surgical treatment option. With an increasing number of men undergoing RP and surviving prostate cancer, clinical management strategies have broadened to improve the preoperative and postoperative patient experience and minimize treatment-related functional consequences. Urinary incontinence is a predictable functional consequence of RP. Recent reviews recommend preoperative and postoperative physical therapist services as the standard of care for men undergoing RP to decrease the severity of urinary incontinence and improve patients' quality of life. Despite compelling evidence, the routine provision of physical therapist services preoperatively and postoperatively for men undergoing RP is limited. The purpose of this case report is to describe the implementation of preoperative and postoperative physical therapist services for men undergoing RP in a US health care system using the knowledge-to-action process and the Consolidated Framework for Implementation Research frameworks.

CASE DESCRIPTION

The implementation process included 4 steps: (1) development of a preoperative and postoperative physical therapist services program; (2) identification of barriers and enablers for implementation; (3) implementation of the program; and (4) evaluation of the effectiveness of the implemented program.

RESULTS

Outcomes from the implementation of a physical therapist services program for men undergoing RP included lower urinary incontinence rates, improved patient satisfaction, and increased physical therapist utilization.

CONCLUSION

This case report documents the implementation of physical therapist services for men undergoing RP. The use of implementation frameworks enabled the identification of unique enablers, barriers, and strategies for the implementation of physical therapist services for men undergoing RP.

IMPACT

Implementing preoperative and postoperative physical therapist services for men undergoing RP improves patient outcomes. The implementation process and outcomes can be considered by other health care systems when developing preoperative and postoperative physical therapist services for men undergoing RP.

[Exercise-Based Prehabilitation In Orthopaedics, Cardiology And Oncology]

Prehabilitation (prehab) aims to prepare patients for surgery, to reduce perioperative complications and to improve postoperative recovery. Pre-operative interventions depend on the indication and the specific patient characteristics and life circumstances. In orthopaedics, the focus is on preoperative improvement of physical performance, function and muscle strength through specific strength, mobility and sensomotoric training. In cardiology, endurance training and respiratory therapy are used in the preoperative phase, as well as coordination and strengthening exercises and occupational therapy to improve physical fitness and performance and reduce cardiovascular risk factors. In oncology, prehab is used preoperatively and also in addition to chemotherapy or radiotherapy to reduce medical side effects and to increase tolerance to cancer therapies (e. g. surgery, chemotherapy, radiotherapy). Exercise interventions in oncology differ according to the type of cancer (e. g. combined strength and endurance training, respiratory therapy, high-intensity interval training and walking). Study results often show positive effects on health resources using prehab. However, further high-quality clinical intervention studies are needed to confirm the clinical benefits of prehab for implementation in routine care.

Exercise- and education-based prehabilitation before total knee arthroplasty: a pilot study

OBJECTIVE

To determine the feasibility and estimates of effects of a supervised exercise- and education-based prehabilitation programme aiming to improve knee functioning compared with usual care in patients awaiting total knee arthroplasty.

DESIGN

A randomized controlled pilot study.

SUBJECTS

Patients receiving primary, unilateral total knee arthroplasty.

METHODS

Patients randomized to the intervention group participated in a personalized 4-8-week prehabilitation programme before surgery. Feasibility of the intervention and self-reported knee functioning, pain, physical performance and hospital stay were assessed at baseline, immediately preoperatively, 6 and 12 weeks after surgery.

RESULTS

Twenty patients (mean age 72.7±5.95 years) were enrolled in this study. The personalized prehabilitation programme was found to be feasible and safe, with an exercise adherence of 90%. Significant medium interaction effects between groups and over time favouring prehabilitation were reported for the sport subscale of the Knee Osteoarthritis Outcome Score (F(3/54) = 2.895, p = 0.043, η² = 0.139) and Tegner Activity Scale (F(2.2/39.1) = 3.20, p = 0.048, η² = 0.151).

CONCLUSION

The absence of adverse events and high adherence to the programme, coupled with beneficial changes shown in the intervention group, support the conduct of a full-scale trial investigating the effectiveness of prehabilitation.

Effects of unimodal or multimodal prehabilitation on patients undergoing surgery for esophagogastric cancer: a systematic review and meta-analysis

PURPOSE

To evaluate the effects of unimodal or multimodal prehabilitation on patients undergoing surgery for esophagogastric cancer.

METHODS

We conducted a systematic search of the PubMed, Embase, CINAHL, Web of Science, and Cochrane Library (CENTRAL) databases from database inception to May 5, 2023, for randomized controlled trials (RCTs) and cohort studies that investigated prehabilitation in the context of esophagogastric cancer. A random-effects model was used for meta-analysis.

RESULTS

We identified 2,994 records and eventually included 12 studies (6 RCTs and 6 cohort studies) with a total of 910 patients. According to random-effects pooled estimates, prehabilitation reduced the incidence of all complications (RR = 0.79, 95% CI: 0.66 to 0.93, P = 0.006), pulmonary complications (RR = 0.61, 95% CI: 0.47 to 0.79, P = 0.0002), and severe complications (RR = 0.63, 95% CI: 0.47 to 0.84, P = 0.002), and shortened the length of stay (MD = -1.92, 95% CI: -3.11 to -0.73, P = 0.002) compared to usual care. However, there were no statistically significant differences in 30-day readmission rates or in-hospital mortality. Subgroup analysis showed that multimodal prehabilitation was effective in reducing the risk of all complications and severe complications, while unimodal prehabilitation was not.

CONCLUSIONS

Our findings suggested that prehabilitation may be beneficial in reducing postoperative complications and length of stay. We recommend preoperative prehabilitation to improve postoperative outcomes and hasten recovery following esophagogastric cancer surgery, and multimodal prehabilitation seems to be more advantageous in reducing complications. However, further studies are needed to confirm these results.

2023 American College of Rheumatology and American Association of Hip and Knee Surgeons Clinical Practice Guideline for the Optimal Timing of Elective Hip or Knee Arthroplasty for Patients With Symptomatic Moderate-to-Severe Osteoarthritis or Advanced Symptomatic Osteonecrosis With Secondary Arthritis for Whom Nonoperative Therapy Is Ineffective

OBJECTIVE

To develop evidence-based consensus recommendations for the optimal timing of hip and knee arthroplasty to improve patient-important outcomes including, but not limited to, pain, function, infection, hospitalization, and death at 1 year for patients with symptomatic and radiographic moderate-to-severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis of the hip or knee who have previously attempted nonoperative therapy, and for whom nonoperative therapy was ineffective, and who have chosen to undergo elective hip or knee arthroplasty (collectively referred to as TJA).

METHODS

We developed 13 clinically relevant population, intervention, comparator, outcomes (PICO) questions. After a systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to rate the quality of evidence (high, moderate, low, or very low), and evidence tables were created. A Voting Panel, including 13 physicians and patients, discussed the PICO questions until consensus was achieved on the direction (for/against) and strength (strong/conditional) of the recommendations.

RESULTS

The panel conditionally recommended against delaying TJA to pursue additional nonoperative treatment including physical therapy, nonsteroidal antiinflammatory drugs, ambulatory aids, and intraarticular injections. It conditionally recommended delaying TJA for nicotine reduction or cessation. The panel conditionally recommended delay for better glycemic control for patients who have diabetes mellitus, although no specific measure or level was identified. There was consensus that obesity by itself was not a reason for delay, but that weight loss should be strongly encouraged, and the increase in operative risk should be discussed. The panel conditionally recommended against delay in patients who have severe deformity or bone loss, or in patients who have a neuropathic joint. Evidence for all recommendations was graded as low or very low quality.

CONCLUSION

This guideline provides evidence-based recommendations regarding the optimal timing of TJA in patients who have symptomatic and radiographic moderate-to-severe osteoarthritis or advanced symptomatic osteonecrosis with secondary arthritis for whom nonoperative therapy was ineffective to improve patient-important outcomes, including pain, function, infection, hospitalization, and death at 1 year. We acknowledge that the evidence is of low quality primarily due to indirectness and hope future research will allow for further refinement of the recommendations.

Effects of tele-prehabilitation on clinical and muscular recovery in patients awaiting knee replacement: protocol of a randomised controlled trial

BACKGROUND

The increasing prevalence of knee osteoarthritis and total knee arthroplasty (TKA) impose a significant socioeconomic burden in developed and developing countries. Prehabilitation (rehabilitation in the weeks immediately before surgery) may be crucial to prepare patients for surgery improving outcomes and reducing assistance costs. Moreover, considering the progress of telemedicine, candidates for TKA could potentially benefit from a tele-prehabilitation programme. We aim to evaluate the effects of a home-based tele-prehabilitation program for patients waiting for total knee replacement.

METHODS AND ANALYSIS

Forty-eight male patients, aged 65-80, on a waiting list for TKA will be recruited and randomly assigned to the tele-prehabilitation intervention or control groups. Both groups will undergo the same 6-week exercise program (five sessions/week) and the same educational session (one per week). The tele-prehabilitation group will perform asynchronous sessions using a tablet, two accelerometers and a balance board (Khymeia, Padova, Italy), while the control group will use a booklet. The Western Ontario and McMaster Universities Osteoarthritis Index Questionnaire, at the end of the prehabilitation, will be the primary outcome. Secondary outcomes will include self-reported outcomes, performance tests and change in expressions of blood and muscle biomarkers. Ten healthy subjects, aged 18-30, will be also recruited for muscle and blood samples collection. They will not undergo any intervention and their data will be used as benchmarks for the intervention and control groups' analyses.

ETHICS AND DISSEMINATION

This randomised controlled trial will be conducted in accordance with the ethical principles of the Declaration of Helsinki. This study has been approved by the Ethics Committee of Vita-Salute San Raffaele University (Milan, Italy. No. 50/INT/2022). The research results will be published in peer-reviewed publications.

Variation in the utilisation of physiotherapy in patients with advanced knee osteoarthritis prior to total knee arthroplasty a systematic review

INTRODUCTION

Due to demographic changes and increasing knee osteoarthritis (KOA) prevalence, the incidence of total knee arthroplasties (TKA) is constantly rising. Clinical practice guidelines for the treatment of KOA unanimously recommend non-surgical interventions such as exercise, education, and weight reduction in overweight patients. The aim of this systematic review is to determine the proportion of patients with end-stage KOA who attended physiotherapy (PT) prior to TKA.

METHODS

A systematic literature search was carried out in the medical databases MEDLINE (via Pubmed), PEDro, and EBSCO in August of 2022. Studies were included regardless of their design, if they reported the proportion of patients with a diagnosis of primary KOA, who participated in PT prior to undergoing TKA. Study quality assessment was performed by two independent authors using the Joanna Briggs Institutes Checklist for studies reporting prevalence data. Results were presented by using a narrative synthesis.

RESULTS

Eighteen studies, comprising 579,718 patients, were identified in this systematic review. PT utilisation prior to TKA ranged from 10% to 73% for patients with advanced KOA. Only two studies showed PT utilisation rates of 60% or higher. Female gender, higher income, better socioeconomic status, higher education levels, older age were associated with PT utilisation. Data for other predicting factors was conflicting.

DISCUSSION

This review shows substantial variation in the utilisation of PT in patients with end-stage KOA. This is concerning, considering the uniform recommendation from clinical practice guidelines for non-surgical treatments like exercise and education in patients with KOA, which are mostly provided by physiotherapists.

Let’s Get Physical! A Comprehensive Review of Pre- and Post-Surgical Interventions Targeting Physical Activity to Improve Pain and Functional Outcomes in Spine Surgery Patients

The goal of this comprehensive review was to synthesize the recent literature on the efficacy of perioperative interventions targeting physical activity to improve pain and functional outcomes in spine surgery patients. Overall, research in this area does not yet permit definitive conclusions. Some evidence suggests that post-surgical interventions may yield more robust long-term outcomes than preoperative interventions, including large effect sizes for disability reduction, although there are no studies directly comparing these surgical approaches. Integrated treatment approaches that include psychosocial intervention components may supplement exercise programs by addressing fear avoidance behaviors that interfere with engagement in activity, thereby maximizing the short- and long-term benefits of exercise. Efforts should be made to test brief, efficient programs that maximize accessibility for surgical patients. Future work in this area should include both subjective and objective indices of physical activity as well as investigating both acute postoperative outcomes and long-term outcomes.

Interactive Combinations Between Gait Speed and Physical Function at Acute Phase Can Predict the Physical Activity at 2 Years After Total Knee Arthroplasty Using Classification and Regression Tree Analysis

OBJECTIVE

To clarify the interactive combinations of various clinical factors associated with physical activity (PA) at 2 years after total knee arthroplasty (TKA) using classification and regression tree (CART) analysis.

DESIGN

A retrospective cohort study.

SETTING

A single university hospital.

PARTICIPANTS

286 patients who underwent TKA (N=286).

MAIN OUTCOME MEASURES

PA was assessed preoperatively, 3 weeks, and 2 years after TKA. Physical functions, namely, 10 m walking test (10MWT), timed Up and Go test, 1-leg standing time, isometric knee extension and flexion strength, knee joint stability, knee pain, femora-tibial angle, and the passive knee extension and flexion angle, were measured before surgery as a baseline and 3 weeks after TKA as acute phase. CART analysis was conducted to clarify the interactive combinations that accurately predict the PA at 2 years after TKA.

RESULTS

The results of CART analysis indicated that gait speed (≥1.05 m/s) at the acute phase after TKA was the primal predictor for the postoperative PA at 2 years. The highest postoperative PA at 2 years was determined by gait speed (≥1.05 m/s) and PA (>74.5) at the acute phase. The PA at baseline and at acute phase, as well as the body mass index were also selected as predictors of postoperative PA at 2 years.

CONCLUSION

The present study suggested that acquiring gait speed (≥1.05 m/s) and PA (>74.5) in the postoperative acute phase is the predictive of a high PA at 2 years after TKA.
