Reporting of post-operative rehabilitation interventions for Total knee arthroplasty: a scoping review

In risk we trust? Making decisions about knee replacement

Risk communication is a key legal and ethical component of shared decision-making. Decisions about total knee replacement, a common surgery, must contend with the fact that a minority of cases result in unintended outcomes, some of which have devastating effects. To understand how risks are communicated during decision-making, we audio-recorded and analysed 62 consultations between surgeons and patients. Various communication methods were evident, including listing risks without elaboration, discussing them in a conversational manner, abrogating discussion of risk, or using decision-tools. Discussion of risks was often brief in nature, and risk communication was sometimes curtailed or deferred by both patients and surgeons. Risks could also be observed to play a part in reinforcing policy norms of the doctor-patient relationship that highlighted patient responsibility. Nevertheless, patients and surgeons in the observed consultations appeared more interested in developing trusting relationships than in discussing risks. Because patients had sometimes experienced considerable deterioration in their knee function before their consultation, were in pain and struggled with mobility, the realities of clinical practice clashed with the policy norms of choice and patient responsibility. Rather, decisions could appear coerced by the disease process rather than being clear-cut examples of self-determination. While policy norms putatively use risk disclosure to frame communication between patients and clinicians as a transaction between customer and technician, the lack of conformity to these norms in the consultations may indicate resistance to this framing. A greater emphasis on determining positive roles for trust and care would help policy to present a nuanced understanding of decision-making. Risk communication could be seen as a factor in the formation of trusting relationships, improving its role in decision-making processes while recognising its inherent tensions with practice.

Risk Factors for Postoperative Knee Stiffness in Patients with Anteromedial Knee Osteoarthritis Undergoing Unicompartmental Knee Arthroplasty with Cemented Prostheses: A Short-Term, Retrospective, Case-Control Study

BACKGROUND The present study was performed to determine the potential risk factors for postoperative knee stiffness in patients with anteromedial knee osteoarthritis undergoing unicompartmental knee arthroplasty with cemented prostheses. MATERIAL AND METHODS This retrospective cohort study evaluated patients with anteromedial knee osteoarthritis who underwent medial unicompartmental knee arthroplasty at our hospital between May 2017 and May 2020. The patients were divided into 2 groups according to their prognosis: those who experienced knee stiffness after undergoing unicompartmental knee arthroplasty and those who did not. The factors associated with stiffness after UKA were identified using univariate analysis. Frequencies are used to express categorical variables, while mean±SD is used to express continuous variables. The t test and chi-square test were used. A multivariate logistic regression model was built to identify the risk factors for postoperative stiffness. RESULTS We included 590 knees in the study after unicompartmental knee arthroplasty. The overall incidence of postoperative stiffness in unicompartmental knee arthroplasty surgery was 10.17%. In terms of the radiological measurements, varus deformity (70.34% vs 29.66%) and tibial component posterior slope angle (4.8±2.0 vs 4.6±2.0, P<0.001) were significantly differences between the 2 groups. Four independent risk factors for stiffness after unicompartmental knee arthroplasty were identified: age (95% CI, 1.022-1.048), varus deformity (95% CI, 1.186-1.192), tibial component posterior slope angle (95% CI, 0.550-0.870), and preoperative maximum flexion (95% CI, 0.896-0.923). CONCLUSIONS The overall incidence of postoperative knee stiffness in patients with anteromedial knee osteoarthritis undergoing unicompartmental knee arthroplasty with cemented prostheses was 10.17%, which was at a moderate level compared to patients with other diseases undergoing unicompartmental knee arthroplasty. Four independent risk factors were identified: age, varus deformity, preoperative maximum flexion, and tibial component posterior slope angle. Awareness these risk factors might help surgeons prevent the occurrence of postoperative knee stiffness in patients with UKA.

Frailty, Illness Perception and Lung Functional Exercise Adherence in Lung Cancer Patients After Thoracoscopic Surgery

Background

Lung cancer patients will have lung damage after surgery, need rehabilitation exercise. Common-sense model has shown the impact of patients' perception of illness on health behaviors. However, for patients with lung cancer after thoracoscopic surgery, there has been no relevant exploration of disease perception.

Objective

The purpose of this study was to investigate the clinical status of patients with lung cancer patients who have undergone thoracoscopic surgery, and to explore the correlation between frailty, disease perception, and lung functional exercise compliance.

Methods

The cross-sectional study included 218 patients with lung cancer after thoracoscopic surgery. We collected participants' frailty, disease perception, exercise adherence, and relevant clinical information. T-test, Chi-square, Linear regression, Pearson's correlation, and mediation analysis were used for statistical analysis of patient data.

Results

We analyzed the data by disease perception with high and low median scores and found significant differences in lymphatic dissection, stool within three days, pain, thoracic drainage tube placement time. Linear regression results show that, after controlling for confounding factors, frailty and disease perception were significantly associated with pulmonary function exercise compliance. The higher the frailty score, the worse the compliance, and the higher the disease perception negative score, the less exercise. Illness perception played a partially mediating role in the association between frailty and lung functional exercise adherence.

Conclusion

Frailty and disease perception have an impact on exercise adherence, therefore, we need to consider these factors in the intervention to improve exercise compliance after thoracoscopic surgery for lung cancer.

Digital Rehabilitation after Knee Arthroplasty: A Multi-Center Prospective Longitudinal Cohort Study

Rehabilitation for total knee replacement (TKA) often involves in-person therapy sessions, which can be time consuming and costly. Digital rehabilitation has the potential to address these limitations, but most of these systems offer standardized protocols without considering the patient's pain, participation, and speed of recovery. Furthermore, most digital systems lack human support in case of need. The aim of this study was to investigate the engagement, safety, and clinical effectiveness of a personalized and adaptative app-based human-supported digital monitoring and rehabilitation program. In this prospective multi-center longitudinal cohort study, 127 patients were included. Undesired events were managed through a smart alert system. Doctors were triggered when there was a suspicion of problems. The drop-out rate, complications and readmissions, PROMS, and satisfaction were collected through the app. There was only 2% readmission. Doctor actions through the platform potentially avoided 57 consultations (85% of alerts). The adherence to the program was 77%, and 89% of the patients would recommend the use of the program. Personalized human-backed-up digital solutions can help to improve the rehabilitation journey of patients after TKA, lower healthcare-related costs by lowering the complication and readmission rate, and improve patient reported outcomes.

Pre- and Post-Operative Rehabilitation Interventions in Patients at Risk of Poor Outcomes Following Knee or Hip Arthroplasty: Protocol for Two Systematic Reviews

Objective

Total knee (TKA) and hip arthroplasty (THA) are successful procedures in treating end-stage osteoarthritis when nonoperative treatments fail. However, a growing body of literature has been reporting suboptimal outcomes following TKA and THA. While pre- and post-operative rehabilitation is imperative to recovery, little is known about their effectiveness for patients at risk of poor outcomes. In the 2 systematic reviews with identical methodology, we aim to evaluate the effectiveness of (a) pre-operative and (b) post-operative rehabilitation interventions for patients at risk of poor outcomes following TKA and THA.

Methods

The 2 systematic reviews will follow the principles and recommendations outlined in the Cochrane Handbook. Only randomized controlled trials (RCTs) and pilot RCTs will be searched in 6 databases: CINAHL, MEDLINE, Embase, Web of Science, Pedro, and OTseeker. Eligible studies including patients at risk of poor outcomes and evaluating rehabilitation interventions following and preceding arthroplasty will be considered for inclusion. Primary outcomes will include performance-based tests and functional patient-reported outcome measures, and secondary outcomes will include health-related quality of life and pain. The quality of eligible RCTs will be evaluated using the Cochrane's risk of bias tool, and the strength of evidence will be assessed using the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE).

Discussion

These reviews will synthesize the evidence regarding the effectiveness of pre-and post-operative rehabilitation interventions for patients at risk of poor outcomes, which in turn may inform practitioners and patients in planning and implementing the most optimal rehabilitation programs to achieve the best outcomes after arthroplasty.

Exploring the Impact and Acceptance of Wearable Sensor Technology for Pre- and Postoperative Rehabilitation in Knee Replacement Patients: A U.K.-Based Pilot Study

Knee replacement operations are common, highly successful procedures that are increasing in frequency. The COVID-19 pandemic has emphasized the need for innovative care pathways that reduce face-to-face appointments. We report on the impact of introducing a wearable sensor for pre- and postoperative rehabilitation of 21 knee replacement patients at 2 hospitals in the U.K.

Understanding barriers and facilitators of exercise adherence after total-knee arthroplasty

PURPOSE

The purpose of this qualitative study is to understand the perceived patient barriers and facilitators of post-surgical exercise adherence in patients undergoing TKA.

MATERIAL AND METHODS

We used an interpretive description approach. Data was gathered using semi-structured qualitative interviews. Participants were interviewed at 8 weeks post-operatively to capture physical, psychological, social and contextual changes and information. Topics that were explored included participants' experience with physical activity and exercise, motivation to perform physical activity, beliefs that exercise will reduce pain, factors that limit their ability to engage in exercise, and the importance of self-regulation in exercise adherence.

RESULTS

This study identified 4 themes within the WHO adherence framework: patient-related factors, condition-related factors, health care system, and social support. In particular, self-regulation, knowledge of exercise, post-operative complications, comorbidities, social support, and lack of guidance from health care providers were identified as personal and environmental characteristics that influence exercise adherence.

CONCLUSION

Exercise adherence is a multidimensional, interconnected construct and future research should focus on understanding the factors, particularly health care system, that impact adherence.IMPLICATIONS FOR REHABILITATIONRehabilitation therapists should aim to foster competence and confidence in post-operative rehabilitation by implementing strategies such as positive-reinforcement, goal setting, and increased education regarding the benefits of exercise.Clinical strategies to improve exercise adherence should be implemented both pre-and-post-operatively.Health care providers should clearly discuss post-operative outcomes and expectations (e.g., complications, etc.) with patients prior to surgery.
