Pain Management After Total Joint Arthroplasty

Transdermal buprenorphine patch as an adjunct to multimodal analgesia after total joint arthroplasty: a retrospective cohort study

Background

Total hip arthroplasty or total knee arthroplasty (THA/TKA) is often associated with varying degrees of pain. In recent years, transdermal buprenorphine (TDB) patch has shown encouraging results for acute postoperative pain control in orthopedic surgery. The aim of our study was to investigate the efficacy and safety of the combination of TDB patch and nonsteroidal anti-inflammatory drugs (NSAIDs) as a multimodal analgesic regimen after THA/TKA.

Methods

Patients who underwent THA and TKA between January 2022 and January 2023 were reviewed. Three postoperative analgesic regimens were selected: Group A (flurbiprofen 50 mg and tramadol 37.5 mg/acetaminophen 325 mg), Group B (flurbiprofen 50 mg and TDB 5 mg), and Group C (Parecoxib 40 mg and TDB 5 mg). The primary outcomes were the Wong-Baker face pain scale revision (FPS-R) scores and the rate of sleep disturbances. Secondary outcomes of the study included the proportion of patients with postoperative pain relief rates categorized as 0%, <50%, ≥50%, and 100%.

Results

The dynamic FPS-R pain scores on day 3 after surgery in Group B were significantly lower than those in Group A for THA (P < 0.017). The dynamic FPS-R pain scores were lowest in Group C on day 2 and 3 after THA and TKA (P < 0.017). Rate of sleep disturbances was significantly lower in Group B for THA and in Group C for TKA, respectively, compared with that in Group A (P < 0.017). The proportion of dynamic pain relief rate ≥50% in Group C was statistically higher than that in Group A for THA (P < 0.017). Rate of adverse reactions among three groups for THA and TKA was not statistically different (P > 0.05).

Conclusion

This study suggests that the combination of TDB patch and NSAIDs is safe and effective for postoperative analgesia after THA/TKA.

'I've just got to take that risk and have faith . . .': The challenge of gaining and maintaining trust in patients undergoing knee surgery with a regional anaesthetic

Traditionally, the focus of the operating theatre has been on conducting safe, efficient surgery with unconscious patients. However, the care of awake patients is now a prominent feature of modern perioperative practise as the volume of surgery performed under regional anaesthesia increases. The aim of this novel study was to understand the experience of being a conscious patient during regional anaesthesia and knee surgery in the perioperative environment. Data were gathered through observation and ethnographic interview and analysis followed a constant comparative grounded theory approach. The concepts of Trust and Faith are identified as recurrent themes highlighted in the data. This article identifies the need to understand patients' expectations regarding the clinical encounter and how subsequent treatment will develop, so that, reasons for any deviation can be discussed openly and an explanation provided. Each clinical encounter takes place within a relationship based upon an uneven distribution of power, enacted through the interaction itself, with the health care professional in a dominant role. It is the responsibility of health care staff to recognise and negate this power imbalance and reinforce trusting relationships so information and treatment options are not presented as a 'fait accompli' but negotiated through jargon free easy to understand language.

Sleep Disturbance Trends in the Short-Term Postoperative Period for Patients Undergoing Total Joint Arthroplasty

BACKGROUND

Patients undergoing total joint arthroplasty (TJA) often experience preoperative/postoperative sleep disturbances. Although sleep quality generally improves > 6 months after surgery, patterns of sleep in the short-term postoperative period are poorly understood. This study sought to (1) characterize sleep disturbance patterns over the 3-month postoperative period and (2) investigate clinical and sociodemographic factors associated with 3-month changes in sleep.

METHODS

This retrospective analysis of prospectively collected data included 104 primary elective TJA patients. Patients were administered the PROMIS Sleep Disturbance questionnaire preoperatively and at 2 weeks, 6 weeks, and 3 months postoperatively. Median sleep scores were compared between time points using Wilcoxon signed-rank tests, stratified by preoperative sleep impairment. A multivariable logistic regression model identified factors associated with 3-month clinically improved sleep.

RESULTS

The percentage of patients reporting sleep within normal limits increased over time: 54.8% preoperatively and 58.0%, 62.5%, and 71.8% at 2 weeks, 6 weeks, and 3 months post-TJA, respectively. Patients with normal preoperative sleep experienced a transient 4.7-point worsening of sleep at 2 weeks ( P = 0.003). For patients with moderate/severe preoperative sleep impairment, sleep significantly improved by 5.4 points at 2 weeks ( P = 0.002), with improvement sustained at 3 months. In multivariable analysis, patients undergoing total hip arthroplasty (versus knee; OR: 3.47, 95% CI: 1.06 to 11.32, P = 0.039) and those with worse preoperative sleep scores (OR: 1.13, 95% CI: 1.04 to 1.23, P = 0.003) were more likely to achieve clinically improved sleep from preoperatively to 3 months postoperatively.

DISCUSSION

Patients experience differing patterns in postoperative sleep changes based on preoperative sleep disturbance. Hip arthroplasty patients are also more likely to experience clinically improved sleep by 3 months compared with knee arthroplasty patients. These results may be used to counsel patients on postoperative expectations and identify patients at greater risk of impaired postoperative sleep.

STUDY DESIGN

Retrospective analysis of prospectively collected data.

Return-to-Function Following Treatment of Dupuytren Contracture With Collagenase Clostridium Histolyticum Versus Fasciectomy

Background: Dupuytren contracture (DC) treatment with collagenase clostridium histolyticum (CCH) has lower associated treatment costs than fasciectomy, but real-world, postprocedure return-to-function data are limited. Methods: This retrospective study used a US claims database and included adults treated for DC with CCH or fasciectomy (first treatment = index date), who had continuous health plan enrollment ≥360 days preindex and ≥90 days postindex (ie, 90-day follow-up). Analgesic use and physical therapy (PT) and occupational therapy (OT) visits during the follow-up were used as surrogate markers for return-to-function. Results: Overall, 1654 and 2745 patients were included in the CCH and fasciectomy cohorts, respectively. A significantly lower percentage of patients in the CCH versus fasciectomy cohort used opioid analgesics (32.3% vs 82.7%; P < .0001), used nonsteroidal anti-inflammatory drugs (8.6% vs 17.2%; P < .0001), or had ≥1 DC-specific PT or OT visit during follow-up (PT, 38.9% vs 45.3% [P < .0001]; OT, 32.8% vs 38.0% [P = .0006]). The mean number of DC-specific PT and OT visits (PT, 2.5 vs 6.4 [P < .0001]; OT, 1.4 vs 1.9 [P < .0001]) per patient was significantly lower in the CCH versus fasciectomy cohort. Conclusions: This analysis using surrogate markers suggests that CCH treatment may allow earlier return-to-function than fasciectomy in adults treated for DC.

Economic Impact of Preoperative Meloxicam IV Administration in Total Knee Arthroplasty: A Randomized Trial Sub-Study

We evaluated the economic impact associated with preoperative meloxicam IV 30 mg vs placebo administration among adult total knee arthroplasty (TKA) recipients enrolled in Phase IIIB NCT03434275 trial. Data on total hospital costs and length of stay (LOS) obtained from the trial were compared between meloxicam IV 30 mg and placebo groups. Patients in the meloxicam IV 30 mg vs placebo group (n = 93 vs 88) incurred an adjusted $2,266 (95% CI: -$1,035, $5,116; p = 0.1689) lower total hospital costs and an adjusted 8.6% (95% confidence interval [CI]: -2.0%, 18.1%; p = 0.1082) shorter LOS. While statistically non-significant, based on 95% CIs, the results from this sub-study may suggest a favorable impact associated with meloxicam IV 30 mg on hospital costs and LOS.

Femoral nerve block versus obturator nerve block for pain management after total knee replacement: A randomized controlled trial protocol

BACKGROUND

Several studies reported short-term analgesic efficacy of obturator nerve block (ONB), as in comparison with the femoral nerve block (FNB) in the treatment of postoperative pain after the total knee replacement (TKR). The optimal method remains under debate. The purpose of our current work is to compare the safety and efficacy of FNB and ONB for postoperative analgesia after TKR.

METHODS

This prospective, randomized, and controlled study was performed from January 2018 to December 2019. It was authorized via the Institutional Review Committee in NO.971 Hospital of the People's Liberation Army Navy (2019-PLAN-132).Two hundred patients were divided randomly into 2 groups, the control group (n = 100) and study group (n = 100). The experimental group received FNB and control groups received ONB. Primary outcome included pain at different time point (Visual Analogue Scale score of anterior knee pain at rest and in motion). The Visual Analogue Scale scores were marked by patients themselves on a paper with a graduated line starting at 0 (no pain) and ending at 10 (the most painful). Opioid consumption was converted to equivalents of oral morphine uniformly for statistical analysis. Secondary outcomes included the knee range of motion, the hospital stay length as well as the postoperative complications such as pulmonary embolism and deep vein thrombosis.

RESULTS

Table 1 will show the clinical outcomes between the 2 groups.

CONCLUSION

This trial would provide an evidence for the use of different types of peripheral nerve blocks in TKR.

Reduced post-operative opioid use decreases length of stay and readmission rates in patients undergoing hip and knee joint arthroplasty

Background

While adequate pain relief is central to patient recovery and satisfaction, opioid use is associated with side effects, adverse drug events and opioid use disorder and therefore is under increased scrutiny. Enhanced surgical recovery protocols include multimodal pain management as a key process, but the impact of opioid dose as an independent variable has not been examined.

Methods

Retrospective analysis of 51,824 hip and knee arthroplasty encounters in a large healthcare system.

Results

Overall, patients receiving treatment with lower doses of opiates had shorter median length of stay (p < 0.001); this earlier discharge had no negative consequences on readmission rates. In particular, patients discharged on day 1 received a lower median morphine milligram equivalent (MME) per day than those who were not discharged (32.5 [IQR: 19.0-50.0] versus 45.0 [26.7-71.2], respectively, p < 0.001). The probability of discharge on day 1 was 41.2% and 19.6% for those patients on lower versus higher MME/day, respectively. Similarly, there was a reduction in odds of readmission of 15.2% (95% CI 5.8-23.6%) for patients on lower doses of MME/day.

Conclusion

Lower MME/day following joint arthroplasty is linked to the probability of discharge on both days 1 and 2 post-surgery as well as reduced odds of readmission. These findings persisted even when adjusting for all other factors, including participation in the enhanced surgical recovery program, the use of a multi-modal analgesic regimen, the presence of complications, patient demographics, and other baseline characteristics. Efforts to reduce opioid use in the peri- and immediate post-operative period, regardless of the mechanism, demonstrated a significant effect on patient outcomes.

Modern instant messaging platform for postoperative follow-up of patients after total joint arthroplasty may reduce re-admission rate

BACKGROUND

Follow-up after artificial joint replacement greatly helps achieve surgical outcomes. Mobile internet technology and mobile terminal equipment may increase the effectiveness of artificial joint replacement. However, only a few studies have evaluated the effectiveness of this technology. We aimed to analyze the reasons and outcomes of patients who used the instant messaging platform after undergoing artificial joint replacement.

METHODS

Among the 548 cases of arthroplasty (250 hips, 298 knees) performed between December 2015 and June 2018 in the Department of Joint Surgery of our institution; 358 (164 hip joints, 194 knee joints) participated in instant messaging platform consultation, whereas the remaining 190 (86 hip joints, 104 knee joints) participated in traditional telephone consultation, as a control group. Follow-up time was from December 2015 to August 2018 (follow-up period was 2-32 months). Data on age, sex, type of surgery, date of surgery, date of discharge, and length of hospital stay were collected from electronic medical records.

RESULTS

We analyzed the consultation contents of 358 patients who participated in instant messaging platform consultation. Counseling was mainly related to pain (13.6%), appointment review (12.4%), activity problems (10.5%), and incision problems (8.9%). Most problems were resolved through online guidance, with 8.4% of patients requiring only outpatient treatment and 2.5% of patients requiring rehospitalization. A total of 190 patients were followed up through traditional telephone consultation; 6.8% of patients required outpatient department treatment and 7.4% were eventually re-admitted.

CONCLUSION

The instant messaging platform consultation service effectively informs patients of potential postoperative problems and helps resolve them. It allows early detection and management of postoperative adverse events, including problems related to medication, wound, and activity, thereby effectively reducing readmission rate.

Comparison of analgesic effect, knee joint function recovery, and safety profiles between pre-operative and post-operative administrations of meloxicam in knee osteoarthritis patients who underwent total knee arthroplasty

AIMS

This study aimed to compare the efficacy and safety of pre-operative and post-operative meloxicam administration regarding post-operative pain control and knee joint function recovery in knee osteoarthritis (KOA) patients who underwent total knee arthroplasty (TKA).

METHODS

Totally, 196 KOA patients who underwent TKA were consecutively enrolled and randomly assigned into pre-operative (N = 98) and post-operative administration group (N = 98) as 1:1 ratio. Pre-operative administration group received meloxicam 15 mg at 24 h pre-operation and 7.5 mg at 4 h, 24 h, 48 h, and 72 h post-operation, respectively. Post-operative administration group received meloxicam 15 mg at 4 h post-operation and 7.5 mg at 24 h, 48 h, and 72 h post-operation, respectively. Pain visual analog scale (VAS) at rest and at flexion, patient's global assessment (PGA), patient-controlled analgesia (PCA) consumption, hospital for special surgery (HSS), knee score, and adverse events were assessed.

RESULTS

Pre-operative meloxicam administration attenuated pain VAS score at rest at 6 h, 12 h, and 24 h; and pain VAS score at flexion at 6 h, 12 h, 24 h, and 48 h; as well as PGA score at 6 h, 12 h, 48 h post-TKA compared with post-operative meloxicam administration. Additional and total consumption of PCA were both decreased in pre-operative meloxicam administration group than post-operative meloxicam administration group, while HSS knee score at 3 months post-TKA was similar between pre-operative and post-operative meloxicam administration groups. Regarding safety, the incidence of adverse events was of no difference between the two groups.

CONCLUSION

Pre-operative administration of meloxicam might assist the post-operative pain management and care in KOA patients who underwent TKA.

Pregabalin and Dexmedetomidine Combined for Pain After Total Knee Arthroplasty or Total Hip Arthroplasty Performed Under Spinal Anesthesia

Pregabalin and dexmedetomidine have been introduced to manage postoperative pain. This study evaluated the effect of the 2 drugs combined on pain in patients undergoing total knee or hip arthroplasty. A total of 124 patients undergoing total knee or hip arthroplasty under spinal anesthesia were randomly assigned to either group C (n=31, placebo), group P (n=33, pregabalin), group PD (n=29, pregabalin and dexmedetomidine), or group D (n=31, dexmedetomidine). One hour before spinal anesthesia, patients received 150 mg of pregabalin or placebo orally, and a bolus dose of 0.5 µg/ kg of intravenous dexmedetomidine was given over 10 minutes before induction of spinal anesthesia. This was followed by a continuous infusion of 0.5 µg/kg/h or the same calculated volume of normal saline until completion of the surgery. Clinically relevant pain for 24 hours postoperatively, including time to first analgesic request, visual analog scale score, ketorolac dose, and volume of patient-controlled analgesia consumed, was recorded. Group C had significantly longer time to first analgesic request, higher visual analog scale scores at rest and on movement, higher ketorolac dose, and higher volume of patient-controlled analgesia for the first 24 hours postoperatively compared with the other groups. Although group PD and group D had less clinically relevant pain than group P, group PD and group D were not significantly different. Dexmedetomidine was more effective than pregabalin for clinically relevant pain. Pregabalin and dexmedetomidine combined had no synergic effect compared with dexmedetomidine alone.

Opiate Pain Medication Consumption in Cigarette Smokers following Total Hip Arthroplasty

Purpose  The purpose of the present study was to assess perception of pain and pain management in smokers versus nonsmokers who received a total hip arthroplasty (THA).

Methods  Patients who underwent THA from 2010 to 2016 were propensity score matched 1:1 based on race, body mass index, age, and sex. This yielded 124 smokers and 124 nonsmokers. Pain intensity was quantified using area under the curve for visual analog scale pain scores. Opioid consumption was determined using a morphine milliequivalent (mEq) conversion algorithm. An independent samples t -test and Chi-square analysis was conducted to assess continuous and categorical variables respectively.

Results  Smokers experienced a nonsignificantly increased pain intensity (198.1 vs. 185.7; p  = 0.063). Smokers demonstrated significantly higher opioid consumption in both immediate postoperative (65.9 vs. 59.3 mEq; p  = 0.045) and 90 days postoperative periods (619.9 vs. 458.9 mEq; p  = 0.029).

Conclusion  Our study demonstrated a nonsignificantly increased pain intensity, and (in both the immediate and 90 days postoperative periods) a significantly higher opioid consumption following THA in patients who smoke cigarettes. This may be due to a relatively small effect size, warranting the need for larger prospective studies. Nevertheless, arthroplasty surgeons should encourage preoperative smoking cessation and alternative nonopioid analgesics to smoking patients receiving THA.

Level of Evidence  This is a level III, retrospective cohort study.

Pain monitoring and management in a rehabilitation setting after total joint replacement

Total hip replacement (THR) and, particularly, total knee replacement (TKR), are painful surgical procedures. Effective postoperative pain management leads to a better and earlier functional recovery and prevents chronic pain. Studies on the control of pain during the postoperative rehabilitation period are not common. The aim of this study is to present results of a perioperative anesthetic protocol, and a pain treatment protocol in use in the Orthopaedic and the Rehabilitation intensive units of our Hospital. 100 patients (50 THR and 50 TKR) were retrospectively included in this observational study. Numeric Rating Scale (NRS) for pain at rest registered in the clinical sheet was retrieved for all patients and analyzed with respect to the spinal anaesthesia given for the surgery, local analgesia, analgesia protocol adopted during the postoperative days in the Orthopaedic Unit, the antalgic treatment given during the stay within the Rehabilitation Unit, the postoperative consumption of rescue pain medication, and any collateral effect due to the analgesic therapy. Patients reached standard functional abilities (walking at least 50 meters and climbing/descending stairs) at a mean length of 8 days without medication-related complications. Mean NRS during the time of stay was 1.3 ± 0.3 for THR and 1.3 ± 0.2 for TKR) and maximum mean NRS was 1.8 ± 0.5 for TKR and 1.8 ± 0.6 for THR. The use of rescue therapy in the rehabilitation guard was correlated with the mean NRS pain and the maximum NRS pain. A very good control of pain with the perioperative anesthetic protocol and pain treatment protocol in use was obtained.

Association Between Acute Pain and Hemodynamic Parameters in a Postoperative Surgical Intensive Care Unit

I conducted a prospective repeated-measure study in the general surgery intensive care unit to investigate the associations among acute postoperative pain, analgesic therapy, and hemodynamic parameters. I selected 33 patients and recorded 84 episodes of pain. I measured intensity of pain and hemodynamic parameters after patients were transferred from the postanesthesia care unit to the general surgery intensive care unit, immediately before analgesic therapy and at 15, 30, and 45 minutes after analgesic therapy. Acute pain increased systolic (SBP), diastolic (DBP), and mean arterial blood pressure (MAP); pulse rate (PR); and arterial oxygen saturation. Fifteen minutes after analgesic therapy, SBP and PR decreased, and DBP, MAP, and oxygen saturation increased. Thirty minutes after therapy, SBP, MAP, and PR decreased, and DBP and oxygen saturation increased. Forty-five minutes after therapy, SBP, MAP, and PR decreased, and DBP and oxygen saturation increased. I saw no significant hemodynamic parameter changes during postoperative episodes of pain.

Multimodal Pain Management in Older Elective Arthroplasty Patients

BACKGROUND

Pain management after elective arthroplasty in older adults is complicated due to the risk of undertreatment of postoperative pain and potential adverse effects from analgesics, notably opioids. Using combinations of analgesics has been proposed as potentially beneficial to achieve pain control with lower opioid doses.

OBJECTIVE

We compared a multimodal pain protocol with a traditional one, in older elective arthroplasty patients, measuring self-rated pain, incidence of postoperative delirium, quantity and cost of opioid analgesics consumed.

METHODS

One hundred fifty-eight patients, 70 years and older, admitted to tertiary care for elective arthroplasty were prospectively assessed postoperative days 1-3. Patients received either traditional postoperative analgesia (acetaminophen plus opioids) or a multimodal pain protocol (acetaminophen, opioids, gabapentin, celecoxib), depending on surgeon preference. Self-rated pain, postoperative delirium, and time to achieve standby-assist ambulation were compared, as were total opioid doses and analgesic costs.

RESULTS

Despite receiving significantly more opioid analgesics (traditional: 166.4 mg morphine-equivalents; multimodal: 442 mg morphine equivalents; t = 10.64, P < .0001), there was no difference in self-rated pain, delirium, or mobility on postoperative days 1-3. Costs were significantly higher in the multimodal group (t = 9.15, P < .0001). Knee arthroplasty was associated with higher pain scores than hip arthroplasty, with no significant difference in opioid usage.

CONCLUSION

A multimodal approach to pain control demonstrated no benefit over traditional postoperative analgesia in elective arthroplasty patients, but with significantly higher amounts of opioid consumed. This poses a potential risk regarding tolerability in frail older adults and results in increased drug costs.
