Consensus on pre-operative total knee replacement education and prehabilitation recommendations: a UK-based modified Delphi study

Improved intra-operative decision making in RA-TKR with the help of pre-operative CT scan

Background

Robotic-assisted total knee replacement (RA-TKR) is a significant advancement in orthopedic surgery, but intra-operative decision-making remains challenging. Pre-operative imaging techniques, particularly CT scans, have gained momentum, providing insights into the patient's anatomy, improving implant positioning and alignment. However, further research is needed to explore their influence on RA-TKR planning and execution.

Materials and methods

The hospital based cross-sectional study was conducted in Orthopedics department of Sparsh Speciality Hospital, Bangalore & Sunshine Hospital, Hyderabad. A total of 1020 participants in the age group over 50 years during the study period were included based on convenient sampling. The axial CT images were taken preoperatively and RA-TKA was done for all the patients.

Results

The study participant's average age was 64.01 ± 7.13. Out of 1020 patients 259 (24.4%) were males and 761 (74.6%) were females. The median femoral, tibia and Polyethylene predicted and the actual component were same with the side of surgery and BMI. The median femoral predicted actual component was significantly higher among the age category of more than 80 years when compared to other age groups. The median femoral, tibia and Polyethylene predicted was higher in males when compared to females.

Conclusion

Pre-operative CT scans enhance RA-TKR procedures by providing precise anatomical insights, enhancing implant placement, and identifying potential issues, improving surgical outcomes and patient satisfaction.

The Effect of QR Code-Supported Patient Training on Total Knee Arthroplasty-Related Problems and Emergency Department Admission Rate

Knee arthroplasty surgery, which is increasingly performed due to increased life expectancy, has positive outcomes, although it can also cause serious health problems following surgery. This study was conducted to evaluate the impact of patient-related education via a QR code on total knee arthroplasty problems and emergency department referral rates. Participants were randomly assigned to intervention (n = 51) and control (n = 51) groups. The intervention group received QR code-supported training. The outcomes were assessed at baseline (preoperative), discharge, and postoperative sixth week. In the intervention group, significantly fewer problems related to total knee arthroplasty occurred at discharge and in week 6, and a higher level of functionality was noted ( P < .05). In week 6, the rate of emergency department admissions was lower, and mean scores for satisfaction with patient training were higher in the intervention group ( P < .05). In conclusion, QR code-supported patient training was effective in reducing the physiological and psychosocial problems related to total knee arthroplasty and the emergency department referral rates. In addition, it provided functional improvement and increased satisfaction with patient training.

Supporting patients to prepare for total knee replacement: Evidence-, theory- and person-based development of a 'Virtual Knee School' digital intervention

INTRODUCTION

Digital delivery of pre-operative total knee replacement (TKR) education and prehabilitation could improve patient outcomes pre- and post-operatively. Rigorously developing digital interventions is vital to help ensure they achieve their intended outcomes whilst mitigating their potential drawbacks.

OBJECTIVE

To develop a pre-operative TKR education and prehabilitation digital intervention, the 'Virtual Knee School' (VKS).

METHODS

The VKS was developed using an evidence-, theory- and person-based approach. This involved a mixed methods design with four phases. The first three focused on planning the VKS. The final phase involved creating a VKS prototype and iteratively refining it through concurrent think-aloud interviews with nine patients who were awaiting/had undergone TKR. Meta-inferences were generated by integrating findings from all the phases. ISRCTN registration of the overall project was obtained on 24 April 2020 (ISRCTN11759773).

RESULTS

Most participants found the VKS prototype acceptable overall and considered it a valuable resource. Conversely, a minority of participants felt the prototype's digital format or content did not meet their individual needs. Participants' feedback was used to refine the prototype's information architecture, design and content. Two meta-inferences were generated and recommend: 1. Comprehensive pre-operative TKR education and prehabilitation support should be rapidly accessible in digital and non-digital formats. 2. Pre-operative TKR digital interventions should employ computer- and self-tailoring to account for patients' individual needs and preferences.

CONCLUSIONS

Integrating evidence, theory and stakeholders' perspectives enabled the development of a promising VKS digital intervention for patients awaiting TKR. The findings suggest future research evaluating the VKS is warranted and provide recommendations for optimising pre-operative TKR care.

PATIENT OR PUBLIC CONTRIBUTION

Patient and Public Involvement (PPI) was central throughout the project. For example, PPI representatives contributed to the project planning, were valued members of the Project Advisory Group, had key roles in developing the VKS prototype and helped disseminate the project findings.

Orthopaedic Nurse Navigators and Total Joint Arthroplasty Preoperative Optimization: Substance Use

Substance use is one of the most common risk factors contributing to complications following total joint arthroplasty. Preoperative optimization programs can help patients modify or stop substance use. The purpose of this study was to provide recommendations and resources that will help nurse navigators standardize and improve preoperative optimization protocols regarding substance use. In a semistructured format, we asked nurse navigators how smoking, alcohol use, and opioid use were addressed. We conducted a literature review and combined findings with nurse navigator reports to create practice recommendations. We recommend consistently referring patients who smoke to smoking cessation programs; using validated screening tools to evaluate alcohol use and involving internists in caring for patients at risk for withdrawal; and involving pain specialists and local resources to assist patients who use opioids. There is a breadth of resources for managing substance use that nurse navigators can utilize to support stronger and more consistent preoperative optimization protocols.

How to develop young physical activity leaders? A Delphi study

The International Society for Physical Activity and Health advocates for increased capability of the physical activity workforce as a key ingredient to a system-based approach. Young leader programmes are gaining traction globally as peers are a primary influence on young people and positive role models are important for increasing or maintaining physical activity. Yet, there is limited understanding of 'what works' for training young physical activity leaders. This study aims to develop a consensus on how to identify and support young people to become physical activity leaders. An iterative three-phased mixed methods Delphi consensus approach. A rapid review focused on the feasibility, acceptability and impact of existing young leader physical activity training (phase one); focus groups (n = 3) and interviews (n = 6) with 15 practitioners and young leaders to examine young physical activity leader training needs (phase two); and a three-round questionnaire process (phase three). Stakeholders (n = 43) from across the public, voluntary and education sectors, academics and young leaders completed all questionnaires. A consensus was reached for 75 statements related to: young leader traits prior to and following training, recruitment methods, training content, delivery format and context, relationships, incentives, and skill development. The Delphi process, combining insight from multi-sectoral stakeholders, identified a range of factors that underpin young leader training programmes. These factors should be applied to develop a curriculum and comprehensive training programme to provide young leaders with the required capability to be effective within their roles, and ultimately support an increase in physical activity amongst children and young people.

Education level has an effect on the recovery of total knee arthroplasty: a retrospective study

OBJECTIVE

This study aimed to observe the relationship between education level and outcomes after total knee arthroplasty (TKA).

METHODS

One thousand two hundred sixty four patients after TKA in our hospital from April 2016 to April 2020 were reviewed. These patients were divided into 4 groups (A who were illiterate, B who had elementary school degree, C who had junior high school degree, D who had senior high school degree or higher) by the educational level, which was blinded to the observers. The postoperative outcomes of KSS score, pain, joint extension and flexion function were observed 1 year after discharged from hospital.

RESULTS

Among 1253 patients met the inclusion criteria, the average age was 68.63 years, the average body mass was 57.73 kg. There are no distinctions among 4 groups one day after the surgery. However, the outcomes of the follow up were that, the KSS score was: 77.84 ± 10.635; 80.70 ± 8.956; 87.92 ± 8.123;91.27 ± 8.262, with significant differences (P < 0.05). The mean VAS scores were: 1.97 ± 1.60; 2.07 ± 1.66; 1.197 ± 1.5265, 1.044 ± 1.4662. Patients in Group C and D had significantly less pain than that in Group A and B (P < 0.05). The knee flexion range of motion (ROM) was: 91.21 ± 11.69°; 91.77 ± 11.95°; 102.12 ± 11.38°; 109.96 ± 10.64°, Group D performed best, with significant differences (P < 0.05). The knee extension ROM were: - 2.41 ± 4.49°; - 0.91 ± 2.82°; - 0.83 ± 2.87°; - 0.35 ± 1.60°, with significant difference between Group D and the others (P < 0.05).

CONCLUSION

Education level affects the outcomes such as VAS score, KSS score, the extension and flexion ROM of the knee after TKA. The patients with higher education level have better outcomes.

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

OBJECTIVE: To assess whether prehabilitation influenced knee functioning before and within the first year after total knee arthroplasty (TKA) surgery. DESIGN: Intervention systematic review with meta-analysis. LITERATURE SEARCH: The authors searched the MEDLINE/PubMED, EMBASE, CINAHL, Cochrane Library, Physiotherapy Evidence Database, Web of Science, and Scopus databases from their inception until March 2022. STUDY SELECTION CITERIA: The authors included peer-reviewed articles comparing preoperative, short-, mid- or long-term effects of exercise-based physical therapy before primary unilateral TKA with TKA without prehabilitation. DATA SYNTHESIS: We assessed bias using the Cochrane Risk-of-Bias tool (ROB 2.0) and therapeutic validity using the i-CONTENT tool. Standardized mean differences (Hedges' g) and 95% confidence intervals (CIs) were calculated for knee functioning. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. RESULTS: Sixteen trials (968 participants) were included; 14 qualified for meta-analysis. Low to very low certainty of evidence favored prehabilitation over no intervention for improving knee functioning before (g = 1.23; 95% CI: 0.49, 1.97) and up to 3 months after TKA (short-term: 1 day to 1 month, g = 0.90; 95% CI: 0.18, 1.61; mid-term: 6 weeks to 3 months, g = 0.45; 95% CI: 0.06, 0.84). There were no significant between-group differences at long-term follow-up (6-12 months, g = 0.07; 95% CI: -0.17, 0.30). CONCLUSION: There was low to very low certainty of evidence that prehabilitation promotes superior knee functioning before and up to 3 months after TKA, compared to TKA alone. The long-term postoperative effects were inconclusive. J Orthop Sports Phys Ther 2022;52(11):709-725 Epub: 20 September 2022. doi:10.2519/jospt.2022.11160.

Content and delivery of pre-operative interventions for patients undergoing total knee replacement: a rapid review

BACKGROUND

Total knee replacement (TKR) is a common operation typically performed for end-stage knee osteoarthritis. Patients awaiting TKR often have poor health-related quality of life. Approximately 20% of patients experience persistent pain post-TKR. Pre-operative TKR interventions could improve pre- and post-operative outcomes, but future research is required to inform their design. This review aimed to identify and synthesize recent literature on the content and delivery of pre-operative TKR interventions to help guide future research and clinical practice.

METHODS

This rapid review included randomized trials of pre-operative TKR interventions ("outcomes studies") and primary studies exploring patients' and/or health professionals' views of pre-operative TKR interventions ("views studies"). Medline, Embase, PsycINFO, CINAHL and the Cochrane Central Register of Controlled Trials were searched for English language studies published between January 2009 and December 2020. Eligible studies' reference lists were screened. Studies were appraised using the Mixed Methods Appraisal Tool. The findings were narratively synthesized using a convergent segregated approach.

RESULTS

From 3263 records identified, 52 studies were included (29 outcomes studies, 21 views studies, two outcomes/views studies). The studies' methodological quality varied but was generally highest in qualitative studies. The outcomes studies investigated education (n=5), exercise (n=20), psychological (n=2), lifestyle (n=1), and/or other interventions (n=5). The views studies addressed education (n=20), exercise (n=3), psychological (n=1), lifestyle (n=4), and/or other interventions (n=1). Only three outcomes studies (two randomized controlled trials (RCTs) and a pilot study) compared the effectiveness of intervention components/delivery approaches. The two RCTs' results suggest that pre-operative TKR exercise interventions are equally effective regardless of whether they include strength or strength plus balance training and whether they are hospital- or home-based. Personal tailoring and using more than one delivery format were associated with improved outcomes and/or perceived as beneficial for multiple intervention types.

CONCLUSIONS

Definitive evidence on the optimal design of pre-operative TKR interventions is lacking. Personal tailoring and employing multiple delivery formats appear to be valuable design elements. Preliminary evidence suggests that including balance training and hospital versus home delivery may not be critical design elements for pre-operative TKR exercise interventions.

Physiotherapy in an advanced rehabilitation pathway for patients after hip and knee arthroplasty: A proposal

Background

Accelerated rehabilitation pathway (ARP) decrease patients’ hospital length of stay (LOS). A lack of evidence exists on physiotherapy management and outcome as part of ARP in South Africa (SA). Our study will aim to determine whether early mobilisation and increased frequency of physiotherapy treatments for participants after hip or knee arthroplasty surgery on post-operative day 0 (POD 0) affect outcome.

Methods/design

A quantitative prospective cohort study incorporating ARP on (n = 60) non-randomised elective hip and knee arthroplasty participants will be compared with a more conservatively managed historical control group (n = 60). The physiotherapy protocol includes early mobilisation and exercises 1–3 h post-operatively on POD 0 and a second mobilisation and exercise session, 1–2 h later. Outcomes measures are as follows: hours for LOS, the WOMAC measured pre-operatively, 6 weeks and 3 months post-operatively, 30-day readmission for safety and cost comparison between the prospective and historical cohorts. Descriptive statistics will be undertaken. A paired t-test will be used to analyse each of the outcome measures across the time periods if data are normally distributed. Length of stay, WOMAC score and cost data will be compared between the groups, using a Mann–Whitney U test. The occurrence of adverse events will be compared between the groups using Pearson’s chi-square tests. The confidence interval will be set at 95% and p = 0.05 will be considered statistically significant.

Discussion

Globally, ARP’s are successfully implemented to manage patients presenting with hip and knee osteoarthritis (OA). Research investigating physiotherapy protocols in an ARP is lacking in the literature.

Conclusion

Achieving the same-day discharge after hip and knee arthroplasty surgeries may help elective surgery backlogs and waiting lists in a more cost-effective manner.

Clinical implications

The same day discharge after arthroplasty may be a cost-effective management option in the future.
