Tranexamic acid for the Latarjet procedure: a randomized controlled trial

Does tranexamic acid reduce elbow swelling and improve early function following arthroscopic arthrolysis? A double-blind randomized controlled trial

BACKGROUND

Tranexamic acid (TXA) reduces bleeding and hematoma rates in open elbow arthrolysis. However, its effects on arthroscopic elbow arthrolysis remain unclear. This study aims to evaluate the effect of TXA on elbow arthroscopic procedures and compare bleeding volume, hemarthrosis, visual analog scale (VAS) for pain, range of motion (ROM), and Mayo Elbow Performance Score (MEPS) in the early postoperative period between patients who received intra-articular TXA and those who did not.

METHODS

A prospective, double-blind, randomized controlled trial enrolling 80 patients with stiff elbows who underwent arthroscopic arthrolysis was performed from January 2021 to December 2022. Intra-articularly, 1 g of TXA in 100 ml of saline or placebo (control group) was administered after the arthroscopic operation according to randomization. Parameters were recorded and compared between the groups, including bleeding volume of drainage, hemoglobin (Hgb) level, ratio of arm and forearm circumference of the surgical side to the contralateral side, grading of hematoma, VAS, ROM, and MEPS within 1 week postoperatively. And during 1 year follow-up, ROM and MEPS were recorded.

RESULTS

All patients enrolled in this study demonstrated significant improvements in ROM (flexion-extension) and MEPS 1 week postoperatively, with no significant differences observed between the 2 groups. Compared to the control group, the TXA group exhibited significant differences in the bleeding volume of drainage (61.45 ± 47.7 ml vs. 89.8 ± 47.0 ml, P = .030) and a higher Hgb level 24 hours postoperatively (13.5 ± 1.5 g/dL vs. 12.6 ± 1.8 g/dL P = .049). While the ratio of arm and forearm circumferences significantly increased 24 hours postoperatively compared to preoperative values in TXA group (1.05 ± 0.06 vs. 1.02 ± 0.04 and 1.02 ± 0.06 vs. 0.98 ± 0.04, with P = .019 and P = .005, respectively), this difference vanished 1 week postoperatively for the ratio of arm circumference. However, it persisted for the ratio of forearm circumference (1.02 ± 0.07 vs. 0.98 ± 0.04, P = .003). Furthermore, there was no significant difference in MEPS, VAS, or ROM between the 2 groups 1 week postoperatively.

CONCLUSION

Patients with stiff elbows who underwent arthroscopic arthrolysis achieved satisfactory clinical outcomes very early postoperatively. Compared to the control group, patients who underwent arthroscopic elbow arthrolysis with intra-articular administration of TXA exhibited significantly less bleeding volume of drainage and slightly higher Hgb levels postoperatively. One week postoperatively, slightly more swelling in the upper arm region was noted in the control group compared to the TXA group. These findings suggest that the intra-articular injection of TXA after arthroscopic release for elbow stiffness may statistically reduce complications related to postoperative bleeding. However, it's clinical relevance needs further investigation.

The Continuous Fragility Index of Statistically Significant Findings in Randomized Controlled Trials That Compare Interventions for Anterior Shoulder Instability

BACKGROUND

Evidence-based care relies on robust research. The fragility index (FI) is used to assess the robustness of statistically significant findings in randomized controlled trials (RCTs). While the traditional FI is limited to dichotomous outcomes, a novel tool, the continuous fragility index (CFI), allows for the assessment of the robustness of continuous outcomes.

PURPOSE

To calculate the CFI of statistically significant continuous outcomes in RCTs evaluating interventions for managing anterior shoulder instability (ASI).

STUDY DESIGN

Meta-analysis; Level of evidence, 2.

METHODS

A search was conducted across the MEDLINE, Embase, and CENTRAL databases for RCTs assessing management strategies for ASI from inception to October 6, 2022. Studies that reported a statistically significant difference between study groups in ≥1 continuous outcome were included. The CFI was calculated and applied to all available RCTs reporting interventions for ASI. Multivariable linear regression was performed between the CFI and various study characteristics as predictors.

RESULTS

There were 27 RCTs, with a total of 1846 shoulders, included. The median sample size was 61 shoulders (IQR, 43). The median CFI across 27 RCTs was 8.2 (IQR, 17.2; 95% CI, 3.6-15.4). The median CFI was 7.9 (IQR, 21; 95% CI, 1-22) for 11 studies comparing surgical methods, 22.6 (IQR, 16; 95% CI, 8.2-30.4) for 6 studies comparing nonsurgical reduction interventions, 2.8 for 3 studies comparing immobilization methods, and 2.4 for 3 studies comparing surgical versus nonsurgical interventions. Significantly, 22 of 57 included outcomes (38.6%) from studies with completed follow-up data had a loss to follow-up exceeding their CFI. Multivariable regression demonstrated that there was a statistically significant positive correlation between a trial's sample size and the CFI of its outcomes (r = 0.23 [95% CI, 0.13-0.33]; P < .001).

CONCLUSION

More than a third of continuous outcomes in ASI trials had a CFI less than the reported loss to follow-up. This carries the significant risk of reversing trial findings and should be considered when evaluating available RCT data. We recommend including the FI, CFI, and loss to follow-up in the abstracts of future RCTs.

Editorial Commentary: Latarjet for Anterior Shoulder Instability Literature Shows Limited Reporting of Outcomes in Female Patients: Female Patients Show Similar Outcomes but Greater Rate of Emergency Department Visits and Possible Greater of Complications

It has been reported that use of the Latarjet procedure for anterior shoulder instability increased 250% from 2008 to 2019. With this increase in use, it is imperative to minimize complications. At present, most literature focuses on male patients, with scant evidence regarding female patients. Outcomes are similar when female with male patients are compared, but female patients have greater postoperative visits to the emergency department than male patients, which requires specific attention during the postoperative period. In addition, the literature reporting complications in female versus male patients after Latarjet is conflicting; some studies show similar rates of complications, whereas other studies show greater rates of adverse events in female patients. Previous consensus statements recommended (1) careful dissection; (2) identification of the musculocutaneous and axillary nerves; (3) prevention of overlateralization of the graft; (4) the use of tranexamic acid to reduce blood loss; (5) accurate screw placement; and (6) careful preparation of the glenoid neck and coracoid to reduce rates of nonunion or delayed union.

Young Collision Athletes Have High Rate of Return to Play and Good Clinical Outcomes Following Open Latarjet Procedure

PURPOSE

To evaluate return to play (RTP), clinical outcomes, and recurrence rates in collision athletes 20 years of age and younger who underwent open Latarjet for anterior shoulder instability.

METHODS

A retrospective review of collision athletes 20 years of age and younger, who underwent an open Latarjet procedure by a single surgeon between the years of 2010-2020 was carried out. Inclusion criteria were 1) collision athlete, 2) underwent open Latarjet procedure, 3) 16-20 years old, and 4) minimum 24-month follow-up. Exclusion criteria were 1) other pathology of the ipsilateral shoulder and 2) noncollision athlete. Rate of RTP, time to RTP, rate of return to preinjury level, the Shoulder Instability Return to Sport after Injury score (SIRSI) score, Subjective Shoulder Value (SSV), visual analogue scale (VAS) scores, and recurrence events were recorded. Quantitative statistical analysis was carried out.

RESULTS

The study included 105 male collision athletes with a mean age of 18.6 ± 1.0 years (range: 17-20). The mean follow-up for patients was 36 ± 26.2 months. A total of 93 (88.6%) RTP at a mean time of 6.3 ± 2.2 months, with 73 (69.5%) returning to their preinjury level of participation. The mean SIRSI score was 69.2 ± 21.8, the mean VAS score was 2.3 ± 2.1, and the mean SSV score was 84.1 ± 16.8. Five patients (4.8%) redislocated their shoulder, with 4 of these requiring a further surgery (3.8%). Two patients (1.9%) reported incidents of subluxation.

CONCLUSIONS

The open Latarjet procedure in young collision athletes results in high rates of RTP, excellent functional outcomes and low recurrence rates at mid-term follow-up. Additionally, complication rates are low in this cohort.

Low complication rate following reverse total shoulder arthroplasty at 90-days follow-up - A systematic review

IMPORTANCE

As reverse total shoulder arthroplasty (RTSA) has become an increasingly common procedure, rates of post-operative complications leading to potential hospital readmission are of greater importance. No previous systematic reviews have focused exclusively on post-operative complications and mortality rates at 90 days post RTSA.

OBJECTIVES

The purpose of this study was to review complication, readmission, and mortality rates within 90 days post RTSA.

EVIDENCE REVIEW

Two independent reviewers performed a literature search using the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines using PubMed, Embase, and Web of Science databases. Only studies reporting on outcomes of RTSA at 90-days follow-up specifically were considered for inclusion.

FINDINGS

Our search included 79,037 shoulders (62.1 ​% female) from a total of 15 studies with an average age of 72.4 ​± ​5.8 years. The overall 90-day re-admission rates were reported in nine studies as 6.1 ​% (4205/69,127) following RTSA. Additionally, a total of five studies reported the overall 90-day mortality rate as 1.1 ​% (19/1733). The overall pooled rate of medical complications was 3.9 ​% (2998/77,826) as reported in 13 studies, at 90-days post-RTSA, with the occurrence of anaemia being the most commonly reported outcomes as 2.9 ​% (1013/34,385) in six studies. The overall rate of surgical complications was 1.1 ​% reported in 13 studies (1327/77,826), with the pooled rate of surgical revisions of 1.5 ​% (607/40,563) at 90-days follow-up. A total of 8, 5, and 3 studies reported rates of dislocation, requirement for closed reduction and glenoid loosening as 0.9 ​% (344/37,995), 0.6 ​% (7/1180), and 0.3 ​% (30/9115) respectively at 90-days following RTSA.

CONCLUSIONS AND RELEVANCE

This study established that the overall rates of mortality and medical and surgical complications are low in the short-term following RTSA, with only 6 ​% of patients requiring re-admission in the first 90 days.

Determining the Effect of Intraoperative TXA on Postoperative Blood Loss in ACDF

STUDY DESIGN

Retrospective cohort study using prospectively collected data.

OBJECTIVE

To determine the effectiveness of intraoperative tranexamic acid (TXA) in anterior cervical discectomy and fusion (ACDF) on postoperative blood loss.

SUMMARY OF BACKGROUND DATA

TXA has been proven to be a safe and effective agent in reducing blood loss after cervical surgery; however, its efficacy when used intraoperatively for ACDF surgeries had yet to be researched. Currently, there are few studies examining the effects of intraoperative TXA in cervical spinal fusion, and none specifically examining TXA use in ACDF.

METHODS

A tertiary medical center's prospectively collected spine registry was queried between 1/1/18 and 12/1/21 for all patients who underwent elective ACDF surgery and received a drain postoperatively. Patients were separated into 2 groups; those who had received intraoperative TXA and those who did not. Baseline demographic and operative variables were collected from the registry. The primary outcome was postoperative blood loss over a 24-hour period. Secondary outcomes included total drain output, intraoperative estimated blood loss, operative duration, drain duration, changes in preoperative to postoperative hemoglobin and hematocrit levels, and rate of transfusions, complications, revisions, and reoperations. Univariate and multivariate regression analyses were performed.

RESULTS

Two hundred eighty-six patients were included. One hundred ninety patients underwent ACDF and did not receive intraoperative TXA, whereas 96 patients underwent ACDF and did receive TXA. There were no differences in any demographic or baseline variables. Multivariate analysis showed intraoperative TXA was associated with shorter drain duration (β=-5.74, 95% CI: -10.9 to -0.53, P =0.031) and reduction in 24-hour drain output (β=-12.2, 95% CI: -19.4 to -4.89, P =0.001) and total drain output (β=-14.0, 95% CI: -22.9 to -5.05, P =0.002).

CONCLUSIONS

TXA use during ACDF procedures leads to a decrease in perioperative blood loss and faster drain removal. TXA is an effective and safe agent for reducing perioperative blood loss in ACDF surgery.

Effect of tranexamic acid on shoulder surgery: an updated meta-analysis of randomized studies

BACKGROUND

The effect of tranexamic acid (TXA) has been proven to be effective in reducing blood loss in lower limb arthroplasty. The aim of this study is to investigate the effect of TXA in shoulder surgery with the updated studies.

MATERIALS AND METHODS

A systematic review and meta-analysis of all the randomized controlled trials were conducted. We compared the outcomes of patients with and without TXA. The PubMed, MEDLINE, EMBASE, and CENTRAL databases were systematically searched for relevant studies.

RESULTS

A total of 14 studies, enrolling 1131 patients, were included for qualitative and quantitative analysis. Our results revealed that TXA was associated with a significant reduction in total volume blood loss (mean difference [MD]: -112.97, P = .0006), drain output (MD: -81.90, P < .00001), hemoglobin changes (MD: -0.55, P = .02), shorter operative time (MD: -6.19, P = .01), and lower risk of hematoma formation (odds ratio: -0.20, P = .01). The postoperative visual analog scale pain score was also significantly better in the TXA group (MD: -0.78, P < .00001). No significant difference was detected in length of hospital stay and incidence of thromboembolization.

CONCLUSION

The usage of TXA in shoulder surgery appeared to be safe and effective in reducing blood loss without any significant complication.

A Study on Distinguishing ChatGPT-Generated and Human-Written Orthopaedic Abstracts by Reviewers: Decoding the Discrepancies

BACKGROUND

ChatGPT (OpenAI Incorporated, Mission District, San Francisco, United States) is an artificial intelligence (AI)-based language model that generates human-resembling texts. This AI-generated literary work is comprehensible and contextually relevant and it is really difficult to differentiate from human-written content. ChatGPT has risen in popularity lately and is widely utilized in scholarly manuscript drafting. The aim of this study is to identify if 1) human reviewers can differentiate between AI-generated and human-written abstracts and 2) AI detectors are currently reliable in detecting AI-generated abstracts.

METHODS

Seven blinded reviewers were asked to read 21 abstracts and differentiate which were AI-generated and which were human-written. The first group consisted of three orthopaedic residents with limited research experience (OR). The second group included three orthopaedic professors with extensive research experience (OP). The seventh reviewer was a non-orthopaedic doctor and acted as a control in terms of expertise. All abstracts were scanned by a plagiarism detector program. The performance of detecting AI-generated abstracts of two different AI detectors was also analyzed. A structured interview was conducted at the end of the survey in order to evaluate the decision-making process utilized by each reviewer.

RESULTS

The OR group managed to identify correctly 34.9% of the abstracts' authorship and the OP group 31.7%. The non-orthopaedic control identified correctly 76.2%. All AI-generated abstracts were 100% unique (0% plagiarism). The first AI detector managed to identify correctly only 9/21 (42.9%) of the abstracts' authors, whereas the second AI detector identified 14/21 (66.6%).

CONCLUSION

Inability to correctly identify AI-generated context poses a significant scientific risk as "false" abstracts can end up in scientific conferences or publications. Neither expertise nor research background was shown to have any meaningful impact on the predictive outcome. Focus on statistical data presentation may help the differentiation process. Further research is warranted in order to highlight which elements could help reveal an AI-generated abstract.

Efficacy and Safety of Tranexamic Acid in Shoulder Arthroscopic Surgery: A Systematic Review and Meta-Analysis

BACKGROUND

Visual clarity during shoulder arthroscopy can ensure an efficient and effective performance of the procedure, and it is highly related to bleeding without a tourniquet. Tranexamic acid (TXA) is widely used in adult reconstruction procedures; however, its use in shoulder arthroscopic operations is a relatively novel topic.

PURPOSE

To analyze the available literature on visual clarity, blood loss, pain control, functional outcomes, and complications after the administration of tranexamic acid in shoulder arthroscopic surgery.

METHODS

A literature search was performed to retrieve randomized controlled trials examining the use of tranexamic acid at the time of shoulder arthroscopic surgery. The literature search included the MEDLINE, Embase, Web of Science, and Cochrane Library databases. The primary outcomes included visual clarity, blood loss, and visual analog scale scores for pain. Secondary outcomes were operative time, irrigation amount used, postoperative shoulder swelling, the need for pressure increase, mean arterial pressure (MAP), functional outcomes, postoperative adverse effects such as deep venous thrombosis, and pulmonary embolism. The outcomes were pooled to perform a meta-analysis.

RESULTS

Seven prospective randomized controlled trials met the inclusion criteria for analysis. All of the included studies performed arthroscopic rotator cuff repair. No significant difference in visual clarity was observed (SMD (standardized mean difference), 0.45 [95% CI(confidence interval), -0.68, 1.59]; p = 0.44) nor in pain score (MD (mean difference), -0.46 [95% CI, -0.97, 0.05]; p = 0.08) between the TXA group and the control group. Two studies found no significant difference in blood loss between the TXA group and the control group. The meta-analysis from five studies demonstrated no significant difference between the TXA and control groups in operative time (MD, -3.51 [95% CI, -15.82, 8.80]; p = 0.58) or irrigation amount used (MD, -2.53 [95% CI, -5.93, 0.87]; p = 0.14). Two trials reported different statistical results in postoperative shoulder swelling. No significant differences regarding the need for pressure increase and MAP were reported between groups. No wound complications or infections or cardiac, thrombotic, or thromboembolic complications were recorded in either group.

CONCLUSION

The use of intravenous or local TXA in shoulder arthroscopic surgery did not increase complications or thromboembolic events, but TXA had no obviously effect of reducing bleeding to obtain a clear visual field or pain release in patients undergoing shoulder arthroscopic surgery.

The effect of single-dose, preoperative intravenous tranexamic acid on early postoperative pain scores after rotator cuff repair: a double-blind, randomized controlled trial

BACKGROUND

Tranexamic acid (TXA) is commonly used in upper and lower limb arthroplasty to limit blood loss and postoperative hematoma formation. The role of TXA in rotator cuff repair (RCR) surgery is less defined. This trial assessed the effect of preoperative TXA on early postoperative pain scores.

METHODS

A randomized double-blind trail was conducted in 89 patients undergoing RCR. Patients were randomized to either 2 g of intravenous TXA or placebo at induction. The primary outcome was visual analog scale (VAS)-pain score at day 3 postoperation, with secondary outcomes including VAS-pain, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), and Constant scores at 2, 8, 24, and 52 weeks.

RESULTS

There was no significant difference in VAS-pain scores between groups at day 3 postoperation. Pain scores were significantly better in the TXA group at 8 weeks. There was no difference between groups at any time point in the ASES or Constant score. The TXA group had improved motion at 6 months with a reduced rate of secondary adhesive capsulitis.

CONCLUSION

TXA did not improve postoperative pain scores after RCR, however, patients who received the intervention demonstrated greater range of motion at 6 months with lower rates of secondary adhesive capsulitis.

Analysis of Athletes Who Did Not Return to Play After Open Latarjet

Background:

The Latarjet procedure is indicated in patients with risk factors for postoperative recurrence, including collision and competitive athletes. However, the factors that prevent athletes from being able return to play (RTP) after the open Latarjet procedure are still unclear and have not been fully elucidated in the literature.

Purpose:

To evaluate patient-reported outcomes and psychological and psychosocial factors associated with athletes who did not RTP after the open Latarjet procedure compared with patients who did RTP.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

We conducted a retrospective review of athletes who underwent the open Latarjet procedure and subsequently did not RTP after a minimum of 12 months. These patients were pair matched in a 2:1 ratio for age, sex, sport, and level of preoperative play with a control group who returned to play. Patients were evaluated for their psychological readiness to return to sport using the Shoulder Instability–Return to Sport after Injury (SIRSI); other measures included the visual analog scale (VAS) for pain and Subjective Shoulder Value (SSV). Multivariate regression models were used to evaluate factors affecting RTP.

Results:

Included were 35 patients in the no-RTP group and 70 patients in the RTP group. In the no-RTP group, 7 patients (20%) passed the SIRSI benchmark of 56, with a mean overall score of 41.5 ± 21.9; in the RTP group, 57 patients (81.4%) passed the SIRSI benchmark, with a mean overall score of 74.5 ± 19.8 (P < .0001 for both). Patients in the RTP group had better SSV (88.0 vs 75.7; P <.0001) and VAS pain (1.7 vs 2.9; P = .0046) scores. Of the athletes who did not return, 18 felt persistent pain/apprehension and 17 felt that it was a natural end to their career or that their lifestyle had changed. Multiple logistic regression revealed that thoughts of having to go through surgery and rehabilitation again was significantly associated with lower RTP (P < .05).

Conclusion:

Patients who did not RTP after open Latarjet exhibited poor psychological readiness to RTP and worse pain VAS and SSV scores compared with patients who did RTP.

Anterior Shoulder Instability Part II-Latarjet, Remplissage, and Glenoid Bone-Grafting-An International Consensus Statement

PURPOSE

The purpose of this study was to establish consensus statements via a modified Delphi process on the Latarjet procedure, remplissage, and glenoid-bone grafting for anterior shoulder instability.

METHODS

A consensus process on the treatment utilizing a modified Delphi technique was conducted, with 65 shoulder surgeons from 14 countries across 5 continents participating. Experts were assigned to one of 9 working groups defined by specific subtopics of interest within anterior shoulder instability.

RESULTS

The technical approaches identified in the statements on the Latarjet procedure and glenoid bone-graft were that a subscapularis split approach should be utilized, and that it is unclear whether a capsular repair is routinely required. Furthermore, despite similar indications, glenoid bone-grafting may be preferred over the Latarjet in patients with bone-loss greater than can be treated with a coracoid graft, and in cases of surgeon preference, failed prior Latarjet or glenoid bone-grafting procedure, and epilepsy. In contrast, the primary indications for a remplissage procedure was either an off-track or engaging Hill-Sachs lesion without severe glenoid bone loss. Additionally, in contrast to the bone-block procedure, complications following remplissage are rare, and loss of shoulder external rotation can be minimized by performing the tenodesis via the safe-zone and not over medializing the fixation.

CONCLUSION

Overall, 89% of statements reached unanimous or strong consensus. The statements that reached unanimous consensus were the prognostic factors that are important to consider in those undergoing a glenoid bone-grafting procedure including age, activity level, Hill-Sachs Lesion, extent of glenoid bone-loss, hyperlaxity, prior surgeries, and arthritic changes. Furthermore, there was unanimous agreement that it is unclear whether a capsular repair is routinely required with a glenoid bone graft, but it may be beneficial in some cases. There was no unanimous agreement on any aspect related to the Latarjet procedure or Remplissage.

Tranexamic Acid for Shoulder Arthroplasty: A Systematic Review and Meta-Analysis

Tranexamic acid (TXA) is an antifibrinolytic agent that has been shown to decrease blood loss and transfusion rates after knee and hip arthroplasty, however with only limited evidence to support its use in shoulder arthroplasty. Therefore, we performed a systematic review and meta-analysis to evaluate the clinical usefulness of tranexamic acid for shoulder arthroplasty. A thorough literature search was conducted across four electronic databases (PubMed, Cochrane Library, Web of Science, Scopus) from inception through to 1 December 2021. The mean difference (MD), odds ratio (OR) or relative risk (RR) and 95% confidence interval (CI) were used to estimate pooled results from studies. Total of 10 studies comprising of 993 patients met the inclusion criteria and were included in the analysis. Blood volume loss in the TXA and non-TXA group was 0.66 ± 0.52 vs. 0.834 ± 0.592 L (MD= -0.15; 95%CI: -0.23 to -0.07; p < 0.001). Change of hemoglobin levels were 2.2 ± 1.0 for TXA group compared to 2.7 ± 1.1 for non-TXA group (MD= -0.51; 95%CI: -0.57 to -0.44; p < 0.001) and hematocrit change was 6.1 ± 2.7% vs. 7.9 ± 3.1%, respectively; (MD= -1.43; 95%CI: -2.27 to -0.59; p < 0.001). Tranexamic acid use for shoulder arthroplasty reduces blood volume loss during and after surgery and reduces drain output and hematocrit change.

Decreasing Inpatient Opioid Use Following Orthognathic Surgery

PURPOSE

Strategies to decrease postoperative opioid use are important for mitigating the immediate and long-term risks associated with their use. We aimed to investigate the impact of perioperative various factors on inpatient opioid needs for patients undergoing orthognathic surgery.

METHODS

This was a retrospective cohort study of all patients who underwent orthognathic surgery performed by the senior author from 2012 to 2018. Patients were grouped into intravenous (IV) acetaminophen and no-IV acetaminophen cohorts. Opioid medications received by patients during hospital stay were converted to mean morphine equivalents (MME) for comparison. Additional factors that influenced opioid consumption, such as transexamic acid (TXA) and postoperative nausea and vomiting (PONV), were identified using univariate analysis. Factors found to have statistical significance were added to a multivariate linear regression model.

RESULTS

319 patients were included. Those who received IV acetaminophen had lower rates of total opioid use (57.3 versus 74.8 MME; P = 0.002) and postoperative opioid use (24.0 versus 37.7 MME; P < 0.001). Perioperative prothrombotic agents, such as TXA, were associated with lower total and postoperative MME (P = 0.005, P = 0.002). Multivariate regression analysis showed that increased PONV resulted in increased postoperative opioid use, whereas perioperative acetaminophen lowered total and postoperative quantities.

CONCLUSIONS

Perioperative IV acetaminophen is an effective method for decreasing inpatient opioid analgesia after orthognathic surgery. Intravenous TXA and PONV control may provide additional benefit to decreasing inpatient opioid consumption. More research as to the mechanisms and ideal clinical applications for both IV acetaminophen and TXA are warranted.

Arthroscopic Bankart Repair Versus Open Latarjet for Recurrent Shoulder Instability in Athletes

Background:

In athletes with recurrent shoulder instability, arthroscopic Bankart repair (ABR) and the open Latarjet procedure (OL) are commonly indicated to restore stability and allow them to return to play (RTP).

Purpose:

To compare the outcomes of ABR and OL in athletes with recurrent shoulder instability.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

We performed a retrospective review of patients with recurrent shoulder instability who underwent ABR and OL and had a minimum 24-month follow-up. Indications for OL over ABR in this population were those considered at high risk for recurrence, including patients with glenohumeral bone loss. The patients were pair-matched in a 1:1 ratio (OL and ABR) by age, sex, sport, and level of preoperative play. We evaluated the rate, level, and timing of RTP, and the Shoulder Instability–Return to Sport after Injury (SIRSI) score between procedures. Additionally we compared the recurrence rate, visual analog scale (VAS) pain score, Subjective Shoulder Value (SSV), Rowe score, satisfaction, and whether patients would undergo the same surgery again.

Results:

Participants included 62 athletes who underwent ABR and 62 who underwent OL, with a mean follow-up of 47.7 months. There was no significant difference between ABR and OL in rate of RTP, return to preinjury level, time to return, SIRSI score, VAS score, SSV, or patient satisfaction. OL resulted in a significantly lower recurrence rate (1.6% vs 16.1% for ABR; P = .009) and a significantly higher Rowe score (mean ± SD, 90.5 ± 12.2 vs 82.2 ± 20.8 for ABR; P = .008). In collision athletes, there was no significant difference between ABR and OL regarding RTP rate (89.1% vs 94.5%; P = .489) or SIRSI score (70.4 ± 24.8 vs 73.8 ± 19.6; P = .426), but OL resulted in a lower recurrence rate (14.5% vs 1.8%; P = .031).

Conclusion:

ABR and OL resulted in excellent clinical outcomes, with high rates of RTP in athletes. However, lower recurrence rates were seen with OL.

Clinical Effectiveness of Intraoperative Tranexamic Acid Use in Shoulder Surgery: A Systematic Review and Meta-analysis

BACKGROUND

Tranexamic acid (TXA) is widely used across surgical specialties to reduce perioperative bleeding. It has been shown to be effective in spinal surgery and lower limb arthroplasty. Among all languages, there are no systematic reviews or meta-analyses investigating its clinical effectiveness for all types of shoulder surgery.

PURPOSE

To investigate the clinical effectiveness of TXA in all types of shoulder surgery, including open and arthroscopic procedures. To investigate the effect of TXA on bleeding and non-bleeding-related outcomes.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

A protocol for the study was designed and registered with PROSPERO (CRD42020185482). The literature search included the MEDLINE, Embase, PsycINFO, and Cochrane Library databases. All randomized controlled trials evaluating the use of TXA against placebo, in all types of shoulder surgery, were included. Assessments were undertaken for risk of bias and certainty of evidence. The primary outcome was total blood loss. Secondary outcomes included those not directly related to bleeding. Data from comparable outcomes were pooled and analyzed quantitatively or descriptively, as appropriate.

RESULTS

Eight randomized controlled trials were included in the systematic review, and data from 7 of these studies were pooled in the meta-analysis. Pooled analysis demonstrated a significant reduction in 2 of 3 outcomes measuring perioperative bleeding with TXA compared with controls: estimated total blood loss (mean difference, -209.66 mL; 95% CI, -389.11 to -30.21; P = .02) and postoperative blood loss as measured by drain output (mean difference, -84.8 mL; 95% CI, -140.04 to -29.56; P = .003). Hemoglobin reduction was reduced but not statistically significant (mean difference, -0.33 g/dL; 95% CI -0.69 to 0.03; P = .07). This result became significant with sensitivity analysis excluding arthroscopic procedures.

CONCLUSION

This systematic review and meta-analysis indicated that TXA was effective in reducing blood loss in shoulder surgery. Larger randomized controlled trials with low risk of bias for specific surgical shoulder procedures are required.

TXA can be used across shoulder surgery to reduced perioperative blood loss. The use of TXA may have other beneficial features, including reduced postoperative pain and reduced operative time.

Open Latarjet Procedure in Athletes Following Failed Prior Instability Surgery Results in Lower Rates of Return to Play

PURPOSE

The purpose of this study was to compare the outcomes of open Latarjet (OL) in competitive athletes with primary shoulder instability versus those with recurrent instability versus those undergoing OL for failed prior instability surgery.

METHODS

A retrospective review of patients who underwent OL with a minimum of 24-month follow-up was performed. Additionally, these were pair-matched in a 1:2:1 ratio for age, gender, sport, level of preoperative play, and follow-up length for primary instability, recurrent instability and failed prior instability surgery. Return to sport, the level of return and the timing of return were assessed. Additionally, recurrence, Visual Analogue Scale for pain (VAS), Subjective Shoulder Value (SSV), Rowe score, Shoulder Instability-Return to Sport after Injury (SIRSI) score, satisfaction, and whether they would undergo the same surgery again were compared.

RESULTS

After pair-matching, a total of 200 patients were included, with a mean age of 22.7 years and a mean follow-up of 38.8 months. Overall, there was no significant difference in any of the clinical outcome scores (VAS, Rowe, SIRSI, SSV) used for the 3 groups (P > 0.05 for all). However, there was a significantly lower rate of return to play for those undergoing OL because of failed prior instability surgery (88% vs 91% vs 64%, P < 0.0001) and for return at the same or a higher level (66% vs 78% vs 56%, P = 0.02). There was no significant difference in the rate of recurrent instability among the 3 groups (6% vs 5% vs 6%, P = 0.95).

CONCLUSION

OL results in excellent clinical outcomes and low recurrence rates for those with primary shoulder instability, those with recurrent instability and those undergoing OL for failed prior instability surgery. However, in those undergoing OL for failed prior stabilization surgery, there was a lower rate of return to play.

Short-term complications of the Latarjet procedure: a systematic review

PURPOSE

The purpose of this study is to evaluate the short-term complication rate following the open and arthroscopic Latarjet procedures and to meta-analyze the studies comparing the 2 approaches.

METHODS

PubMed was searched according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines to find clinical and biomechanical studies comparing complication rates in open and arthroscopic Latarjet procedures. A literature search of MEDLINE, Embase, and the Cochrane Library was performed based on the PRISMA guidelines. Clinical studies reporting on the complications following the open or arthroscopic Latarjet were included. Meta-analysis was performed for comparative studies using Review Manager, version 5.3. A P value of <.05 was considered statistically significant.

RESULTS

Overall, 89 studies (Level of Evidence [LOE] I: 2, LOE II: 2, LOE III: 24, LOE IV: 61) met inclusion criteria, with 7175 shoulders. Following the open Latarjet procedure, the overall complication rate was 6.1%, with a 1.9% occurrence of graft-related complications, 1.1% hardware, 1.1% wound, 0.9% nerve, and 1.2% other complications. Following the arthroscopic Latarjet procedure, the overall complication rate was 6.8%, with a 3.2% occurrence of graft-related complications, 1.9% hardware, 0.5% wound, 0.7% nerve, and 0.5% other complications. Complications were reported in 7 studies comparing 379 patients treated with the open Latarjet and 531 treated with the arthroscopic Latarjet, with no statistically significant difference between the two (P = .81).

CONCLUSION

Our study established that the overall complication rate following the Latarjet procedure was 6%-7%, with the most common complication being graft-related. Furthermore, based on the current evidence, there is no significant difference in the complication rate between the open and arthroscopic Latarjet procedures.

No difference in 90-day complication rate following open versus arthroscopic Latarjet procedure

The purpose of this study was to compare the 90-day complication rate between the open and arthroscopic Latarjet procedure. A retrospective review of patients who underwent an open or arthroscopic Latarjet procedure at NYU Langone Health between 2012 and 2019 was performed. The complications, readmissions, and reoperations within 90 days were assessed. Outcomes were compared between the two approaches, and a p value of < 0.05 was considered to be statistically significant. The study included 150 patients (open: 110; arthroscopic: 40), with no patients lost to follow-up within the first 90 days. Both cohorts were similar in terms of patient demographics. No intra-operative complications were observed in either group. Overall, there were 4 post-operative complications with the open approach and 2 with the arthroscopic approach (3.6% and 5.0%, respectively; n.s.) during the study period. Three patients required a readmission within the 90-day period; one patient in both groups required a revision Latarjet for graft fracture, and one patient in the open Latarjet required irrigation and debridement for deep infection (n.s.). With the open approach, there were 2 (2.3%) wound complications, 1 graft complication, and 1 (1.1%) nerve injury. With the arthroscopic approach, there was 1 (2.8%) wound complication and 1 (2.8%) hardware complication. The safety, and 90-day complication and readmission profile of arthroscopic Latarjet is similar to open Latarjet procedure. LEVEL OF EVIDENCE: Level III.

Tranexamic Acid Has No Effect on Postoperative Hemarthrosis or Pain Control After Anterior Cruciate Ligament Reconstruction Using Bone-Patellar Tendon-Bone Autograft: A Double-Blind, Randomized, Controlled Trial

PURPOSE

The purpose of this double-blind, randomized, controlled trial was to evaluate the use of intravenous (IV) tranexamic acid (TXA) in patients undergoing primary bone-patellar tendon-bone (BPTB) anterior cruciate ligament reconstruction (ACLR) regarding postoperative hemarthrosis, pain, opioid consumption, and quadriceps atrophy and activation.

METHODS

A controlled, randomized, double-blind trial was conducted in 110 patients who underwent ACLR with BPTB autograft. Patients were equally randomized to the control and experimental groups. The experimental group received two 1-g boluses of IV TXA, one prior to tourniquet inflation and one prior to wound closure; the control group did not receive TXA. If a clinically significant hemarthrosis was evident, the knee was aspirated and the volume of blood (in milliliters) was recorded. Additionally, we recorded perioperative blood loss (in milliliters); visual analog scale scores on postoperative days 1, 4, and 7 and at postoperative weeks 1, 6, and 12; postoperative opioid consumption on postoperative days 1, 4, and 7; range of motion (ROM) and ability to perform a straight leg raise at postoperative weeks 1, 6, and 12; and preoperative and postoperative thigh circumference ratio.

RESULTS

There was no significant difference in perioperative blood loss between the TXA and control groups (32.5 mL vs 35.6 mL, P = .47). In the TXA group, 23 knees were aspirated; in the control group, 26 knees were aspirated (P = .56). No significant difference in postoperative hemarthrosis volume was seen in patients who received IV TXA versus those who did not (26.7 mL vs 37.3 mL, P = .12). There was no significant difference in visual analog scale scores between the 2 groups (P = .15); in addition, there was no difference in postoperative opioid consumption (P = .33). No significant difference in ROM, ability to perform a straight leg raise, or postoperative thigh circumference ratio was observed (P > .05 for all).

CONCLUSIONS

IV TXA in patients who undergo ACLR with BPTB autograft does not significantly impact perioperative blood loss, postoperative hemarthrosis, or postoperative pain levels. Additionally, no significant differences were seen in early postoperative recovery regarding ROM or quadriceps reactivation.

Editorial Commentary: The Benefits of Tranexamic Acid May Outweigh Risks in Arthroscopy and Sports Medicine

Tranexamic acid (TXA) is an antifibrinolytic that lowers the risk of hemarthrosis-related surgical complications and has been extensively studied in orthopaedic trauma surgery, primary and revision total joint replacement, open shoulder reconstruction, and spine surgery. Its use, however, has been minimally studied in orthopaedic sport medicine, and, in particular, arthroscopic surgery. Despite being an inexpensive medication with a minimal side effect profile, there has been a paucity of Level I and II studies to support or refute its use in some of the most common procedures performed in orthopaedic surgery. TXA may be of small benefit in routine partial meniscectomy or routine, outpatient, anterior cruciate ligament reconstruction. However, although there are potential risks and side effects of TXA, the risk is very low, the cost is very low, and even a small benefit may justify its use.
