The effects of nonsteroidal anti-inflammatory medications after rotator cuff surgery: a randomized, double-blind, placebo-controlled trial

Effect of post-operative NSAID use on rotator cuff repair outcomes

Background

The impact of non-steroidal anti-inflammatory drugs (NSAIDs) on rotator cuff repair is an ongoing area of study within orthopedics, with conflicting results in current literature. Despite concerns over the deleterious effects of NSAIDs on rotator cuff healing, they are becoming an integral part of a multimodal post-operative pain control regiment. The purpose of this study was to compare post-operative patient-reported outcomes (PROs), complications rates, and retear rates of arthroscopic rotator cuff repairs in patients using ibuprofen post-operatively to those who abstained from NSAIDs for six weeks after surgery. It was hypothesized that a short course of ibuprofen post-operatively would not lead to inferior PRO scores, increased retear rates, nor increased complication rates after arthroscopic rotator cuff repair.

Methods

Patients of the primary surgeon who underwent arthroscopic rotator cuff repair between 2012 and 2022 were evaluated by retrospective chart review. In May 2017 the primary surgeon changed his protocol from avoiding NSAIDs for six weeks after surgery to routinely prescribing two weeks of Ibuprofen 800 mg TID post-operatively. Patients who avoided NSAIDs for six weeks were compared to patients who were prescribed NSAIDs post-operatively. Patient demographic data, pre-operative MRI results, pre-operative and post-operative PROs were collected from the EMR. Additionally, post-operative complications and repair failures requiring reoperation within one year were evaluated.

Results

125 patients met inclusion criteria for this study with 36 patients in the NSAID group and 89 in the no NSAID group. When comparing improvement in PROs, the NSAID group reached MCID at one year in 83.8 % of patients and the no NSAID group reached MCID at one year in 73.9 % of patients. There was no significant difference between the groups in reaching MCID improvement at one year (p = 0.471). Five post-operative complications were reported in the no NSAID group and two in the NSAID group (5.7 % vs 5.4 %, respectively, p = 0.827). Finally, there was no significant difference in the percentage of post-operative rotator cuff repair failures requiring revision in the first year between the groups (2.3 % vs 2.7 %, p = 1.000).

Conclusion

There was no difference in percent of patients improving their PRO by the MCID between the groups that used ibuprofen and the group that did not. There was also no difference in post-operative complication rates and rates of symptomatic retear requiring reoperation between the groups. This supports that a short course of NSAIDs post-operatively, specifically ibuprofen, after rotator cuff repair does not increase reoperation rates nor lead to a clinically significant decrease in PROs at one year.

Arthroscopic Surgery Combined With Platelet-Rich Plasma Does Not Significantly Improve Pain, Function, Complications, and Retear Rate Compared With Arthroscopic Surgery Alone for Full-Thickness Rotator Cuff Tears: A Systematic Review and Meta-analysis

PURPOSE

To evaluate the effectiveness and safety of arthroscopic surgery combined with platelet-rich plasma (PRP) compared with arthroscopic surgery alone in the treatment of patients with full-thickness rotator cuff tears.

METHODS

The Cochrane Library, PubMed, Embase, Scopus, EBSCO, Web of Science, China National Knowledge Infrastructure, and Wanfang Database were systematically searched from inception to November 2023. Subject words combined with free words were used to collect randomized controlled trials focusing on arthroscopic surgery combined with PRP in the treatment of full-thickness rotator cuff tears. The assessment of evidence quality employed the Cochrane Collaboration risk of bias tool, and data analysis was performed using RevMan 5.3 software.

RESULTS

A total of 9 studies with 537 patients were included. The meta-analysis revealed that compared with the arthroscopic surgery alone group, the summary result of University of California Los Angeles score scores in the arthroscopic combined with PRP group was (mean difference [MD] = 1.08, 95% confidence interval [CI] 0.19∼1.97, P = .02), subgroup analysis of surgical suture method visual analog scale (VAS) single-row (MD = -1.00, 95% CI -1.50 to -0.50, P < .0001), VAS double-row (MD = -0.10, 95% CI -0.17 to -0.02, P = .02), and Constant-Murley score single-row (MD = 3.49, 95% CI 0.32∼6.66, P = .03), the difference was statistically significant, and the differences in VAS, Constant-Murley score, and Quick Disabilities of the Arm, Shoulder and Hand, complications, and retear rate were not statistically significant.

CONCLUSIONS

Patients undergoing arthroscopic repair combined with PRP treatment showed no difference in pain, function, complications, and retear rate compared with those treated with arthroscopic surgery alone.

Functional recovery prediction during rehabilitation after rotator cuff tears by decision support system

BACKGROUND

Today's rehabilitation decision-making still relies on conventional methods and different specific targeted rehabilitation protocols. Our study focuses on the decision support system for early rehabilitation after rotator cuff (RC) tears repair, where a multicriteria decision-making framework (MCDM) is applied for the prediction of successful functional recovery and selection of a rehabilitation protocol.

OBJECTIVE

To identify factors that affect recovery outcomes and to develop a decision support system methodology for predicting functional recovery outcomes at early rehabilitation after RC repair.

METHODS

Twelve rehabilitation experts were involved in the design, calibration, and evaluation of a rehabilitation protocol based on the proposed decision support system constructed using the MCDM framework. For the development of a decision support system, 20 patients after RC surgery undergoing outpatient rehabilitation were enrolled in a prospective cohort clinical trial.

RESULTS

The MCDM framework (SWARA method) sensitively assesses different criteria and determines the corresponding criteria weights that were similar to criteria weights assessed subjectively by rehabilitation experts. The assignment of patients into the classes, according to the heuristic evaluation method based on expert opinion and the standard qualitative evaluation methods showed the validity of MCDM methods remain the best new alternative in predicting recovery during rehabilitation.

CONCLUSIONS

The results of this paper show that sustainable rehabilitation is an area that is quite suitable for the use of MCDM. The most of rehabilitation protocols are based on traditional methods and approaches, but the sensitive results showed the validity of MCDM methods and remains the best new alternative in prediction recovery protocols during rehabilitation.

Non-steroidal Anti-inflammatory Drugs and Cyclooxygenase-2 Inhibitors Do Not Affect Healing After Rotator Cuff Repair: A Systematic Review and Meta-analysis

PURPOSE

To determine whether non-steroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase-2 (COX-2) inhibitors affect healing rate, functional outcomes, and patient satisfaction after rotator cuff repair.

METHODS

Medline, EMBASE, PsychINFO and the Cochrane Library were searched for randomized controlled trials (RCTs) investigating the use of NSAIDs and COX-2 inhibitors after arthroscopic rotator cuff repair. Primary outcomes included healing and retear rate, determined by radiological imaging. Secondary outcomes included shoulder-specific outcome measures and the visual analog scale (VAS). Risk of bias was graded using the Cochrane risk-of-bias v2.0 tool. The GRADE framework was used to assess certainty of findings.

RESULTS

Seven RCTs with a total of 507 patients were included (298 randomized to NSAID/COX-2 vs 209 randomized to control). NSAIDs use did not yield a difference in retear rate (P = .77). NSAIDs were shown to significantly reduce pain in the perioperative period (P = .01); however, no significant difference was present at a minimum of 6 months (P = .11). COX-2 inhibitors did not significantly reduce pain (P = .15). Quantitative analysis of ASES and UCLA scores showed NSAIDs significantly improved functional outcomes versus control (P = .004). COX-2 inhibitors did not significantly improve functional outcomes (P = .15). Two trials were deemed "low" risk of bias, four trials were graded to have "some concerns", and one trial was graded to have "high" risk of bias. Retear rate and functional PROMs were deemed to have "low" certainty. VAS pain scale was graded to have "moderate" certainty.

CONCLUSIONS

This systematic review and meta-analysis indicates that NSAIDs do not affect healing rate after arthroscopic rotator cuff repair, but they do significantly improve postoperative pain and functional outcomes. No significant difference was seen in pain or functional outcomes with the use of COX-2 inhibitors.

Rotator cuff tears

Rotator cuff tears are the most common upper extremity condition seen by primary care and orthopaedic surgeons, with a spectrum ranging from tendinopathy to full-thickness tears with arthritic change. Some tears are traumatic, but most rotator cuff problems are degenerative. Not all tears are symptomatic and not all progress, and many patients in whom tears become more extensive do not experience symptom worsening. Hence, a standard algorithm for managing patients is challenging. The pathophysiology of rotator cuff tears is complex and encompasses an interplay between the tendon, bone and muscle. Rotator cuff tears begin as degenerative changes within the tendon, with matrix disorganization and inflammatory changes. Subsequently, tears progress to partial-thickness and then full-thickness tears. Muscle quality, as evidenced by the overall size of the muscle and intramuscular fatty infiltration, also influences symptoms, tear progression and the outcomes of surgery. Treatment depends primarily on symptoms, with non-operative management sufficient for most patients with rotator cuff problems. Modern arthroscopic repair techniques have improved recovery, but outcomes are still limited by a lack of understanding of how to improve tendon to bone healing in many patients.

Cannabidiol for Postoperative Pain Control After Arthroscopic Rotator Cuff Repair Demonstrates No Deficits in Patient-Reported Outcomes Versus Placebo: 1-Year Follow-up of a Randomized Controlled Trial

Background

Cannabidiol (CBD) has been shown recently to positively affect patient pain and satisfaction immediately after arthroscopic rotator cuff repair (ARCR). However, it is unclear whether the addition of CBD to a perioperative regimen could affect postoperative outcomes.

Purpose

To evaluate patient-reported outcomes among patients who underwent ARCR and received buccally absorbed CBD or an identical placebo for early postoperative pain management at 1-year follow-up.

Study Design

Randomized controlled trial; Level of evidence, 2.

Methods

Eligible patients had previously participated in a multicenter, placebo-controlled, randomized, double-blinded trial that evaluated the analgesic effects of CBD in the immediate postoperative period after ARCR. The experimental group received 25 mg of CBD 3 times/day if <80 kg and 50 mg of CBD 3 times/day if >80 kg for 14 days, with the control group receiving an identical placebo. The following outcomes were assessed at minimum 1-year follow-up: visual analog scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE), and patient satisfaction. The rates of achievement of the Patient Acceptable Symptom State (PASS) were compared based on ASES at latest follow-up. Continuous and categorical variables were compared with the Mann-Whitney U test and Fisher exact test, respectively.

Results

Follow-up was obtained from 83 of 99 patients (83.8%) who completed the original trial. There were no significant differences between the CBD and control groups with respect to age, sex, body mass index, rate of concomitant procedures, or number of anchors used intraoperatively. At 1-year follow-up, there were no significant differences between the CBD and control groups in VAS pain (0.8 vs 1.2, P = .38), ASES (93.0 vs 91.1, P = .71), SANE (87.6 vs 90.1, P = .24), or satisfaction (97.4 vs 95.4, P = .41). A majority of patients achieved the PASS (81.0% [CBD] vs 77.5% [control]; P = .79).

Conclusion

Perioperative use of CBD for pain control among patients undergoing ARCR did not result in any significant deficits in pain, satisfaction, or patient-reported outcomes at 1-year postoperatively compared with a placebo control group. These findings suggest that CBD can be considered in a postoperative multimodal pain management regimen without detrimental effects on outcome.

Arthroscopy Association of Canada Position Statement on Opioid Prescription After Arthroscopic Surgery

Background

Despite the ongoing opioid epidemic, most patients are still prescribed a significant number of opioid medications for pain management after arthroscopic surgery. There is a need for consensus among orthopaedic surgeons and solutions to aid providers in analgesic strategies that reduce the use of opioid pain medications.

Purpose

This position statement was developed with a comprehensive systematic review and meta-analysis of exclusively randomized controlled trials (RCTs) to synthesize the best available evidence for managing acute postoperative pain after arthroscopic surgery.

Study Design

Position statement.

Methods

The Embase, MEDLINE, PubMed, Scopus, and Web of Science databases were searched from inception until August 10, 2022. Keywords included arthroscopy, opioids, analgesia, and pain, and associated variations. We included exclusively RCTs on adult patients to gather the best available evidence for managing acute postoperative pain after arthroscopic surgery. Patient characteristics, pain, and opioid data were extracted, data were analyzed, and trial bias was evaluated.

Results

A total of 21 RCTs were identified related to the prescription of opioid-sparing pain medication after arthroscopic surgery. The following recommendations regarding noninvasive, postoperative pain management strategies were made: (1) multimodal oral nonopioid analgesic regimens-including at least 1 of acetaminophen-a nonsteroidal anti-inflammatory drug-can significantly reduce opioid consumption with no change in pain scores; (2) cryotherapy is likely to help with pain management, although the evidence on the optimal method of application (continuous-flow vs ice pack application) is unclear; (3) and (4) limited RCT evidence supports the efficacy of transcutaneous electrical nerve stimulation and relaxation exercises in reducing opioid consumption after arthroscopy; and (5) limited RCT evidence exists against the efficacy of transdermal lidocaine patches in reducing opioid consumption.

Conclusion

A range of nonopioid strategies exist that can reduce postarthroscopic procedural opioid consumption with equivalent vocal pain outcomes. Optimal strategies include multimodal analgesia with education and restricted/reduced opioid prescription.

The Safety Assessment of Irrigation Fluid Management for Shoulder Arthroscopy and Its Effect on Postoperative Efficacy

OBJECTIVE

Fluid extravasation is a potentially dangerous complication associated with shoulder arthroscopy. Most relevant studies have involved respiratory system, while the primary purpose was to reveal the effects of the fluid extravasation on cardiovascular system and postoperative function.

METHODS

The clinical data of 92 patients was retrospective analyzed, in which 84 cases with rotator cuff injury, three cases with shoulder instability, three cases with fractures of the greater tuberosity of the humerus, and two cases with frozen shoulder. All the patients were undergoing shoulder arthroscopy. The relationship between the basic information of the patients and cardiac index (CI) or pulse pressure variation (PPV) were evaluated by linear regression analysis. The change of CI or PPV at different states were evaluated by the one-way analysis of variance. The liquid retention (TR) and postoperative clinical outcomes was analyzed using linear regression.

RESULTS

The preoperative CI was affected by anesthesia status and body position, while PPV was not affected. Multivariate mixed-effects model analysis of CI found that there was a statistically significant difference in groups of older than 55 years old and those with obesity (BMI > 24). After the operation, the retention of irrigation fluid significantly influenced the circumference of the deltoid (P < 0.001 (95%CI: [0.30, 1.00])), but not on the circumference of the deltoid, neck, and arm. The multivariate analysis of the American Shoulder and Elbow Surgery (ASES) scores at 3 and 6 months after surgery showed that the fluid retention volume was correlated with the ASES score at 3 months after surgery, especially when the retention volume was greater than 2 L (P = 0.001 (95%). %CI: [-12.49, -3.22]).

CONCLUSION

The retention of irrigation fluid after shoulder arthroscopic surgery causes swelling of local limbs, and has an effect on peripheral blood vessels, which is mainly reflected in its influence on PPV and the postoperative function. Therefore, surgeons need to improve their surgical technique, shorten the operation time and reduce fluid retention.

Non-selective NSAIDs do not increase retear rates post-arthroscopic rotator cuff repair: A meta-analysis

BACKGROUND

Arthroscopic rotator cuff repairs (RCRs) are known to be associated with substantial pain and post-operative pain management is critical in overall patients' outcomes. Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used oral medications and can reduce opioid usage. However, controversies arise due to its postulated effect on postoperative tendon healing. As the evidence of safety and efficacy of NSAIDs remains unclear, this study aims to investigate the effect of NSAIDs on retear rates and clinical outcomes.

METHODS

A systematic search of four databases (PubMed, EMBASE, Scopus, and Cochrane Library) was conducted, identifying studies that compared cohorts with post-RCR NSAIDs use versus control groups without NSAID use. Meta-analysis was conducted for retear rate as well as pain and functional outcomes (Visual Analogue Scale and American Shoulder and Elbow Surgeons Shoulder score). Subgroup analysis was conducted for retear rates to determine the overall treatment effect of including selective COX-2 inhibitors.

RESULTS

Six studies were included in the meta-analysis. The total baseline cohort size was 916, with 443 (48.3%) patients in the NSAID group and 473 (51.6%) patients in the control group. There were no statistically significant differences in the baseline characteristics between the two groups. Meta-analysis between the two groups showed that there were no statistically significant differences in retear rates (p ​= ​0.70), early and late post-operative Visual Analogue Scale score (p ​= ​0.10 and p ​= ​0.10, respectively) and latest American Shoulder and Elbow Surgeons Shoulder score (p ​= ​0.31). However, subgroup analysis of retear rates revealed a statistically significant difference between the subgroup including COX-2 selective inhibitor versus non-selective COX inhibitor (p ​< ​0.01).

CONCLUSION

NSAID use in post-arthroscopic RCR pain relief does not increase retear rates and can provide similar clinical outcomes compared to a non-NSAID regimen.

Opioid-Sparing Strategies in Arthroscopic Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Opioid overprescription is a problem in orthopaedic surgery. Arthroscopic surgery, given its minimally invasive nature, represents an opportunity to minimize opioid prescription and consumption by using effective pain management adjuncts. Thus, the primary question posed in this study was which noninvasive pain management modalities can effectively manage pain and reduce opioid intake after arthroscopic surgery.

METHODS

The databases PubMed, MEDLINE, EMBASE, Scopus, and Web of Science were searched on August 10, 2022. Randomized controlled trials (RCTs) evaluating noninvasive pain management strategies in arthroscopy patients were evaluated. Eligible studies were selected through a systematic screening process. Meta-analysis was performed for pain scores and opioid consumption at time points which had sufficient data available.

RESULTS

Twenty-one RCTs were included, with a total of 2,148 patients undergoing shoulder, knee, and hip arthroscopy. Meta-analysis comparing nonopioid, oral analgesic regimens, with or without patient education components, with the standard of care or placebo demonstrated no difference in pain scores at 24 hours, 4 to 7 days, or 14 days postoperatively. Nonopioid regimens also resulted in significantly lower opioid consumption in the first 24 hours postoperatively (mean difference, -37.02 mg oral morphine equivalents, 95% confidence interval, -74.01 to -0.03). Transcutaneous electrical nerve stimulation (TENS), cryotherapy, and zolpidem were also found to effectively manage pain and reduce opioid use in a limited number of studies.

CONCLUSIONS

A range of noninvasive pain management strategies exist to manage pain and reduce opioid use after arthroscopic procedures. The strongest evidence base supports the use of multimodal nonopioid oral analgesics, with some studies incorporating patient education components. Some evidence supports the efficacy of TENS, cryotherapy, and nonbenzodiazepine sleeping aids. Direction from governing bodies is an important next step to incorporate these adjuncts into routine clinical practice to manage pain and reduce the amount of opioids prescribed and consumed after arthroscopic surgery.

Use of Opioids in the Early Postoperative Period After Arthroscopic Rotator Cuff Repair: A Systematic Review

Background:

Postoperative treatment plans after orthopaedic procedures frequently include opioids for pain relief.

Purpose:

To evaluate opioid use in the early postoperative phase after arthroscopic rotator cuff repair (ARCR) to develop a procedure-specific understanding of the current role of opioids in pain management for this procedure.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

A PubMed search was used to identify eligible studies. Data on patient demographics, visual analog scale pain scores, and opioid use patterns (in morphine milligram equivalents [MMEs]) were collected and assessed. Cumulative MMEs were reported on postoperative day (POD) zero, and mean MMEs were reported on subsequent PODs (days 1, 2, 3, 5, 7, and 14). Metaregression, I² indices, and Cochran Q tests were used to evaluate study variation, heterogeneity, and variance.

Results:

A total of 1487 patients in 22 studies were included in the analysis. An estimated 51% (95% CI, 31%-70%) of patients with nerve blocks (NBs) were opioid-free through POD-0 versus 40% (95% CI, 1.2%-97%) of patients without NBs, which increased to 65% (95% CI, 55%-74%) versus 25% (95% CI, 1.7%-86%) by POD-1. Opioid requirements were highest in the first 72 hours after ARCR. NB use reduced opioid requirement on POD-0 compared with no NB use (15.8 vs 45.0 MMEs, respectively; P < .001) but did not reduce requirements after that. In addition, NB use led to a statistically significant increase in opioid requirements on POD-7 (28.6 vs 9.5 MMEs, respectively; P < .001). Using a model that assumes stable opioid requirements between our time points, weighted mean cumulative opioid consumption was 163 MMEs in the first week and 273 MMEs in the first 2 weeks (150 and 287 MMEs in patients with NB; 180 and 261 MMEs in patients without NB, respectively).

Conclusion:

Opioid use is relatively common in the early postoperative period after ARCR. Pain scores and opioid requirements may spike on POD-1; however, patients should be educated and reassured that they will gradually decrease usage over the initial 2-week postoperative period.

Safety and Efficacy of Postoperative Nonsteroidal Anti-inflammatory Drugs in Sports Medicine

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used for multimodal pain control after surgery. These medications work by selective or nonselective inhibition of cyclooxygenase, which has downstream effects on thromboxanes, prostaglandins, and prostacyclins. Clinical studies have shown beneficial effects for alleviating pain and reducing opioid consumption after surgery. Within hip arthroscopy, there is evidence that postoperative NSAIDs can also reduce the risk of symptomatic heterotopic bone formation. However, preclinical and animal studies have raised concern over the effect of NSAIDs on bone and soft-tissue healing. In addition, selective and nonselective cyclooxygenase 2 inhibitors may have different safety profiles regarding postoperative soft-tissue healing. The purpose of this review was to outline the mechanisms of action, efficacy, and effect on soft-tissue healing of postoperative NSAIDs and to provide evidence-based recommendations for appropriate use.
