The Effect of Preoperative Behavioral Intervention on Pain, Anxiety, Opioid Use, and Function in Patients Undergoing Total Knee Arthroplasty: A Randomized Controlled Study

The effect of preoperative education on postoperative pain and function after orthopedic surgery: A systematic review and meta-analysis

OBJECTIVES

To systematically review the effect of preoperative education on reducing postoperative pain and disability in the short-term and long-term for patients undergoing orthopedic surgery.

METHODS

Pertinent randomized controlled trials were retrieved from PubMed, Cochrane Central, Embase, Medline, Scopus and CINAHL from their inception until September 10, 2023. Two authors independently conducted study selection, data extraction, and methodological quality assessment. This review was registered in PROSPERO (CRD42023470282).

RESULTS

A total of 37 RCTs were included with 27 of them being pooled for meta-analysis. Low certainty of evidence indicated that there was a small effect of preoperative education (standardized mean difference = - 0.23, 95 % CI = [- 0.39, - 0.07], p = 0.004) or combined preoperative intervention (standardized mean difference = - 0.25, 95 % CI = [- 0.41, - 0.09], p = 0.003) on postoperative pain relief.

CONCLUSIONS

Preoperative education and combined preoperative intervention only had a short-term effect on postoperative pain relief, while they were not superior to usual care in postoperative functional recovery, either short-term or long-term.

PRACTICE IMPLICATIONS

Both preoperative education and combined preoperative intervention are effective in pain control around a week postoperatively. However, optimal contents, durations, and dose of education warrant further investigation.

Psychosocial Interventions to Reduce Post operative Pain in Total Knee Arthroplasty: A Systematic Review

Background: Total knee arthroplasty (TKA) is a common surgical remedy for patients with end-stage osteoarthritis. Although TKA is generally effective, a significant number of patients experience chronic post-surgical pain. Psychosocial interventions have increasingly become an area of interest in pain management following surgical procedures. Purpose: We aimed to evaluate the impact of pre-operative, peri-operative, and post-operative psychosocial interventions on reducing the likelihood of developing chronic pain after TKA. Methods: We performed a systematic review following the Cochrane guidelines and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. A comprehensive search strategy was employed using PubMed, Embase, and Cochrane Central Register of Controlled Trials. Inclusion criteria were (1) patients undergoing; (2) pain outcome assessed ≥1 month post-operatively; (3) prospective and longitudinal study design (eg, randomized controlled trial, experimental non-randomized trial, cohort, case-control studies with measurement of exposure prior to outcome); (4) English language; and (5) psychosocial intervention (cognitive-behavioral, biopsychosocial, dialectical behavioral, psychoeducation, mindfulness, meditation, psychotherapy, relaxation, mind-body therapies, hypnosis). Exclusion criteria were non-primary literature (eg, review articles), non-peer-reviewed studies, and conference proceedings. The methodological quality of included studies was assessed using Cochrane's tool for Risk of Bias 2 (RoB 2), the methodological index for non-randomized studies (MINORS), and the Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I). Results: Of 4297 studies reviewed with title and abstract, 4160 were excluded. Of the remaining 137 studies that underwent full-text review, 122 were excluded using the same inclusion and exclusion criteria, and 15 studies were included. Our review indicates a variable but positive impact of psychosocial interventions, such as pre-operative education, relaxation techniques, and cognitive-behavioral therapy, on post-TKA pain. Of the 15 included studies, 9 studies found that psychosocial interventions reduced post-TKA pain. Our review also suggests that cognitive-behavioral therapy may aid in reducing kinesiophobia, pain catastrophizing, and knee pain intensity. For the 12 randomized studies, the risk of bias was deemed "high" concerns for 3 studies, "some" concerns for 5 studies, and "low" concerns for 4 studies. For the 3 non-randomized studies, the risk of bias was deemed "moderate" due to confounding bias. Conclusions: This systematic review of level-I and level-II studies found that the integration of psychosocial interventions into care protocols for TKA offers benefits including improved patient satisfaction and quality of life and reduced health care costs. Limitations include heterogeneity in intervention types and outcomes measured and the varying levels of risk of bias across studies, which may affect the generalizability of the findings. The findings support a broader adoption of holistic, patient-centered approaches in pain management after TKA, emphasizing the importance of psychological well-being for optimal patient outcomes. However, the evidence is limited and constitutes a strong impetus for the further study of these interventions.

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.

Evaluation of Neuropathic Pain after Total Knee Arthroplasty: Do Yellow Flags Matter?

Up to 20% of total knee arthroplasty (TKA) patients continue to experience chronic postsurgical pain. Various factors have been identified as potential contributors, including so-called "yellow flags", encompassing symptoms of depression, anxiety, and catastrophizing, which were examined in this study to assess their predictive value concerning functional outcomes after TKA.

METHODS

Fifty TKA patients were categorized into high-risk and low-risk groups based on clinical assessment, demographic data, medication, and patient-reported outcome measures (DN4, SF-36, WOMAC, NRS, Fibromyalgia Survey Questionnaire, Pain Catastrophizing Scale, and Hospital Anxiety and Depression Scale). Postoperative outcomes within six months after TKA were then compared.

RESULTS

Both groups exhibited significant (p < 0.001) improvements in all WOMAC and NRS subscales, as well as in the physical function, role physical, pain, and energy/fatigue subdomains of the SF-36 after six months, while the high-risk group showed lower WOMAC scores regarding stiffness (19.0 ± 18.3 vs. 27.2 ± 20.7, p < 0.001) and pain (13.5 ± 13.3 vs. 15.1 ± 16.3, p = 0.029). The high-risk group showed significantly worse preoperative DN4 scores (1.8 ± 1.3 vs. 3.0 ± 1.1, p = 0.002) than the low-risk group, which persisted for one day (2.3 ± 1.2 vs. 3.5 ± 1.5, p = 0.005) and six weeks (2.2 ± 1.9 vs. 3.6 ± 2.3, p = 0.041) postoperatively.

CONCLUSIONS

Our results indicate that pre-existing yellow flags contribute to a more challenging early postoperative phase, underscoring the importance of considering individual patient characteristics and psychological factors to optimize TKA outcomes.

SuRxgWell: study protocol for a randomized controlled trial of telemedicine-based digital cognitive behavioral intervention for high anxiety and depression among patients undergoing elective hip and knee arthroplasty surgery

BACKGROUND

Mood disorders (anxiety, depression), sleep disorders, and catastrophizing lead to increased post-operative pain perception, increase in postoperative opioid consumption, decreased engagement with physical activity, and increased resource utilization in surgical patients. Psychosocial disorders significantly affect postoperative outcome. Unfortunately, studies focused on perioperative psychological assessment and treatment are scarce. We propose to test whether digital cognitive behavioral intervention (dCBI) can help surgical patients. dCBI such as RxWell™ is a proven treatment for mood disorders in medical patients such as reducing depression in patients with inflammatory bowel disease. We hypothesize that RxWell™ will also be effective in surgical patients. This study aims to test whether RxWell™ can improve preoperative mood disorders and subsequently reduce postoperative pain and opioid requirement in patients scheduled for primary total hip and knee arthroplasty (THA, TKA). We named the trial as the SuRxgWell trial.

METHODS

This is a randomized, controlled trial that will enroll primary and unilateral THA or TKA patients with anxiety and/or depression symptoms before surgery to receive the SuRxgWell dCBI program and investigate its impact on postoperative outcomes including postoperative pain, anxiety, depression, sleep disorder, and catastrophizing. After signing an informed consent, subjects will be screened using the PROMIS questionnaires, and subjects with a T-score of ≥ 60 on the short Patient-Reported Outcomes Measurement Information System (PROMIS) 4a Anxiety and/or short PROMIS 4a Depression questionnaires will be randomized to either usual care (control group) or the cognitive behavioral intervention, RxWell™, plus usual care (intervention group). The control group will receive information on how to locate tools to address anxiety and depression, whereas the intervention group will have access to SuRxgWell 1 month prior to surgery and up to 3 months after surgery. The allocation will be 3:1 (intervention to control). Investigators will be blinded, but research coordinators approaching patients and research subjects will not. The primary outcome will be day of surgery anxiety or depression symptoms measured with the PROMIS Short Form v1.0 -Anxiety 4a/Depression and Generalized Anxiety Disorder Measure (GAD-7) and Patient Health Questionnaire (PHQ-8). Secondary end points include measuring other health-related quality of life outcomes including sleep disturbance, fatigue, ability to participate in social roles, pain interference, cognitive function, pain catastrophizing, and physical function. Other secondary outcomes include collecting data about preoperative and postoperative pain scores, and pain medication usage, and orthopedic functional recovery at baseline, day of surgery, and 1, 2, and 3 months after the surgery with the Pain Catastrophizing Scale, the Knee injury and Osteoarthritis Outcome Score (KOOS), and Hip injury and Osteoarthritis Outcome Score (HOOS). In addition, subjects will be asked to complete a GAD-7 and PHQ-8 questionnaires bi-weekly (via the RxWell™ app for the interventional group or REDCAP for the control group). Data about postsurgical complications, and resource utilization will also be recorded. We will also receive monthly reports measuring the usage and engagement of RxWell use for each participant randomized to that arm. The primary hypotheses will be assessed with intention-to-treat estimates, and differences in primary outcome will be tested using independent two sample t-tests. This trial is registered to the ClinicalTrials.gov database (NCT05658796) and supported by the DAPM, UPMC Health Plan, and the NIH.

DISCUSSION

Our trial will evaluate the feasibility of digital cognitive behavioral intervention as a perioperative tool to improve anxiety and depression before and after major orthopedic surgery in comparison to education. If digital cognitive behavioral intervention proves to be effective, this might have important clinical implications, reducing the incidence of chronic postsurgical pain and improving outcomes.

Lifestyle medicine for anxiety symptoms: A meta-analysis of randomized controlled trials

BACKGROUND

Lifestyle medicine (LM) is gaining increasing attention as a treatment option for anxiety, but the current state of evidence has not yet been systematically examined.

METHODS

Six electronic databases were systematically searched from inception to February 2022. Randomized controlled trials (RCTs) comparing the effects of multicomponent LM interventions on anxiety symptoms with either care-as-usual, waitlist, no intervention, or attention control group on anxiety symptoms were identified.

RESULTS

A total of 53 RCTs with 18,894 participants were included for qualitative synthesis, in which 45 RCTs with data available were included for meta-analysis. Multicomponent LM intervention was significantly more effective than the control groups in reducing anxiety symptoms at immediate posttreatment (d = 0.19, p < .001) and at short-term follow-up (d = 0.29, p < .001). However, no significant difference at medium-term was found (p = .14), whereas more studies are needed to study the long-term effects. The subgroup analyses suggested that baseline anxiety symptoms was a significant moderator, suggesting that those with moderate level of baseline anxiety symptoms appeared to have greater improvements (d = 0.66, p < .05).

LIMITATIONS

Minimal anxiety symptoms at baseline contributed to the floor effect and influenced the degree of improvement. The included RCTs had a high risk of bias in general with potential publication bias detected.

CONCLUSION

The findings of this meta-analysis provided support for the positive effects of multicomponent LM interventions for anxiety symptoms. Future research is needed to determine the long-term effects of multicimponent LM and the optimal baseline anxiety severity.

Efficacy and Adverse Reactions of Arthroscopic Half-Moon Plate Invasive Surgery in Patients with Acute Knee Pain (AKP): Systematic Review and Meta-Analysis

Objective

To evaluate the efficacy and adverse reactions of arthroscopic half-moon plate invasive surgery (DEB) in patients with knee pain (AKP) using meta-analysis techniques.

Methods

The computer retrieves from the English databases PubMed, EMBASE, Cochrane Library, and Web of Science and the Chinese databases China Knowledge Network, Wanfang Database, VIP Database, and China Biomedical Literature Database to collect information about DEB therapeutic AKP randomized controlled trial. Develop criteria for documentation inclusion and exclusion, evaluate the quality and bias risk of literature, and compare differences in efficacy and adverse responses before and after DEB treatment and other conservative treatments.

Results

A total of 14 randomized controlled trials and 1464 AKP patients were included in the study, with follow-up duration of 1-12 months. The total knee scores for DEB at 1, 3, 6, and 12 months after treatment were significantly better than baseline levels (1 month: WMD = 34.56, P = 0.02; 3 months: WMD = 27.73, P = 0.0001; 6 months: SMD = 2.38, P = 0.0001; 12 months: SMD = 1.69, P = 0.001). At 6 months of follow-up, DEB improved knee function better than HA (SMD = 0.47, P = 0.003), and during follow-up for 12 months, DEB relieved knee pain (SMD = 0.55, P = 0.0007) and improved knee function (SMD = 0.88, P = 0.0001) which is significantly better than HA. DEB was less effective at improving knee function in 1, 3, and 12 months than DEB joint HA injections (1 month P = 004; 3 months P = 0.01; 12 months P = 0.03). At 6 and 12 months of follow-up, DEB was better at pain relief and improved function than ozone (P > 0.05). DEB and glucocorticosteroids have similar effects in pain relief and improved function at various follow-up times. In terms of adverse reactions, DEB does not increase the risk of adverse events compared to HA (OR = 0.96, P = 0.85).

Conclusion

Compared to HA and ozone, DEB is a more effective treatment for AKP joints, while DEB is combined with HA. The clinical efficacy of injection therapy AKP is better than that of DEB alone.
