Adequate visual clarity is paramount to performing arthroscopic shoulder surgery safely, efficiently, and effectively. The addition of epinephrine in irrigation fluid, and the intravenous or local administration of tranexamic acid (TXA) have independently been reported to decrease bleeding thereby improving the surgeon's visualization during arthroscopic shoulder procedures. No study has compared the effect of systemic administered TXA, epinephrine added in the irrigation fluid or the combination of both TXA and epinephrine on visual clarity during shoulder arthroscopy with a placebo group. The purpose of this study is to determine if intravenous TXA is a safe alternative to epinephrine delivered by a pressure-controlled pump in improving arthroscopic shoulder visualization during arthroscopic procedures and whether using both TXA and epinephrine together has an additive effect in improving visualization. The design of the study was a double-blinded, randomized controlled trial with four 1:1:1:1 parallel groups conducted at one center. Patients aged ≥18 years undergoing arthroscopic shoulder procedures including rotator cuff repair, arthroscopic biceps tenotomy/tenodesis, distal clavicle excision, subacromial decompression and labral repair by five fellowship-trained upper extremity surgeons were randomized into one of four arms: Pressure pump-controlled regular saline irrigation fluid (control), epinephrine (1ml of 1:1000) mixed in irrigation fluid (EPI), 1g intravenous TXA (TXA), and epinephrine and TXA (EPI/TXA). Visualization was rated on a 4-point Likert scale every 15 minutes with 0 indicating ‘poor’ quality and 3 indicating ‘excellent’ quality. The primary outcome measure was the unweighted mean of these ratings. Secondary outcomes included mean arterial blood pressure (MAP), surgery duration, surgery complexity, and adverse events within the first postoperative week. One hundred and twenty-eight participants with a mean age (± SD) of 56 (± 11) years were randomized. Mean visualization quality for the control, TXA, EPI, and EPI/TXA groups were 2.1 (±0.40), 2.1 (±0.52), 2.6 (±0.37), 2.6 (±0.35), respectively. In a regression model with visual quality as the dependent variable, the presence/absence of EPI was the most significant predictor of visualization quality (R=0.525; p < 0 .001). TXA presence/absence had no effect, and there was no interaction between TXA and EPI. The addition of MAP and surgery duration strengthened the model (R=0.529; p < 0 .001). Increased MAP and surgery duration were both associated with decreased visualization quality. When surgery duration was controlled, surgery complexity was not a significant predictor of visualization quality. No adverse events were recorded in any of the groups. Intravenous administration of TXA is not an effective alternative to epinephrine in the irrigation fluid to improve visualization during routine arthroscopic shoulder surgeries although its application is safe. There is no additional improvement in visualization when TXA is used in combination with epinephrine beyond the effect of epinephrine alone

The use of cannabis is increasingly medically relevant as it is legalized and gains acceptance more broadly. However, the effects of marijuana use on postoperative outcomes following orthopedic surgery have not been well-characterized. This study seeks to illuminate the relationship between marijuana use and the incidence postoperative complications including: DVT, PE, nonunion, and infection following common orthopedic procedures. This study was conducted using a national orthopaedic claims insurance database. We identified all patients undergoing knee arthroscopy, shoulder arthroscopy, operatively managed long bone fractures (humerus, femur, tibia and/or fibula, and radius and/or ulna), and single-level lumbar fusion. The proportion of patients within each surgery cohort who had a diagnostic code for marijuana dependence was assessed. The rates of DVT, PE, and infection within 90 days were assessed for all patients. The rate of nonunion was assessed for the long bone fracture and lumbar fusion cohorts. Univariate analyses of marijuana dependence on all outcomes were performed, followed by a multivariate logistic regression analysis controlling for known patient comorbidities. We identified 1,113,944 knee arthroscopy, 747,938 shoulder arthroscopy, 88,891 lumbar fusion, and 37,163 long bone fracture patients. Out of the 1,987,936 patients, 24,404 patients had a diagnostic code for marijuana dependence. Within all four surgical subgroups, the marijuana dependence cohort experienced increased rates of infection, PE, and DVT, as well as increased rates of nonunion in the lumbar fusion and long bone fracture populations. In the multivariate analyses controlling for a variety of patient risk factors including tobacco use, marijuana dependence was identified as an independent risk factor for infection within all four surgical subgroups (Knee: OR 1.85, p < 0.001; Shoulder: OR 1.65, p < 0.001; Spine: OR 1.45, p < 0.001; Long bone: OR 1.28, p < 0.001), and for nonunion in the lumbar fusion (OR 1.38, p < 0.001) and long bone fracture (OR 1.31, p < 0.001) subgroups. Our data suggests that marijuana dependence may be associated with increased rates of infection and nonunion following a variety of orthopaedic procedures. During preoperative evaluation, surgeons may consider marijuana use as a potential risk factor for postoperative complications, especially within the context of marijuana legalization. Future research into this relationship is necessary

Magnetic resonance imaging (MRI) is the gold standard for the diagnosis of the pathologies affecting the glenohumeral joint and the rotator cuff diseases. MRI allows to highlight anatomic discontinuities of both muscles and tendons. However, MRI diagnostic accuracy has not proven to be highly sensitive in distinguishing between a partial-thickness tear and a full-thickness rotator cuff tear. The purpose of this study was to determine if MRI under axial traction can be helpful in increasing MRI sensitivity to identify partial-thickness rotator cuff tears. The study included 10 patients (4 males and 6 females) who had clinical examination and MRI suggesting a partial-thickness rotator cuff tear. They were candidates for shoulder arthroscopy because of persistent symptoms after at least three months of conservative treatment. The patients underwent a new MRI (under axial traction: MRI-AT) with a 4-kg weight applied to the affected arm. Then the patients underwent arthroscopy to confirm the diagnosis. Patients with a suspected full-thickness rotator cuff tear were excluded from the study. Patients’ average age was 52.4 years, and the dominant side was affected in 77.7% of the cases. Preoperative Constant-Murley Score was 57. MRI-AT showed that 3 patients were affected by a complete tear of the rotator cuff, 3 patients by a partial-thickness rotator cuff tear and 4 patients had no lesion. The analysis of data showed that: under axial traction the subacromial space increased by 0,2 mm (P value = 0,001075), the superior glenohumeral space decreased by 2.4 mm (P value = 0,07414), the inferior glenohumeral space increased by 0.3 mm (P value = 0,02942), the acromial angle decreased by 1.9° (P value = 0,0002104) and the acromion-glenohumeral angle decreased by 0.3° (P-value = 0,01974). Two experienced evaluators analyzed previous standard MRI and MRI-AT scans in a double-blinded fashion, with inter-rater evaluation of all the images and measures. Intraclass correlation coefficient (ICC) has been utilized to assess the reliability of the measures performed by different operators. ICC always resulted in more than 0.7, showing a high concordance among values in the same group. A comparative evaluation between standard MRI and MRI-AT has been conducted to highlight possible discrepancies and this has been compared to intraoperative findings. Concordance of the values was 89% between standard MRI and MRI-AT and 100% between MRI under axial traction and intraoperative findings. This study showed a high correlation between the diagnosis achieved with MRI-AT and the intraoperative arthroscopic findings. The use of MRI-AT in clinical practice may improve the diagnostic sensitivity of this method to detect a partial-thickness rotator cuff tear

Orthopaedic surgeons prescribe more opioids than any other surgical speciality. Opioids remain the analgesic of choice following arthroscopic knee and shoulder surgery. There is growing evidence that opioid-sparing protocols may reduce postoperative opioid consumption while adequately addressing patients’ pain. However, there are a lack of prospective, comparative trials evaluating their effectiveness. The objective of the current randomized controlled trial (RCT) was to evaluate the efficacy of a multi-modal, opioid-sparing approach to postoperative pain management in patients undergoing arthroscopic shoulder and knee surgery.

The NO PAin trial is a pragmatic, definitive RCT (NCT04566250) enrolling 200 adult patients undergoing outpatient shoulder or knee arthroscopy. Patients are randomly assigned in a 1:1 ratio to an opioid-sparing group or standard of care. The opioid-sparing group receives a three-pronged prescription package consisting of 1) a non-opioid prescription: naproxen, acetaminophen and pantoprazole, 2) a limited opioid “rescue prescription” of hydromorphone, and 3) a patient education infographic. The control group is the current standard of care as per the treating surgeon, which consists of an opioid analgesic. The primary outcome of interest is oral morphine equivalent (OME) consumption up to 6 weeks postoperatively. The secondary outcomes are postoperative pain scores, patient satisfaction, quantity of OMEs prescribed and number of opioid refills. Patients are followed at both 2 and 6 weeks postoperatively. Data analysts and outcome assessors are blinded to the treatment groups.

As of December 1, 2021 we have enrolled 166 patients, reaching 83% of target enrolment. Based on the current recruitment rate, we anticipate that enrolment will be completed by the end of January 2022 with final follow-up and study close out completed by March of 2022. The final results will be released at the Canadian Orthopaedic Association Meeting in June 2022 and be presented as follows. The mean difference in OME consumption was XX (95%CI: YY-YY, p=X). The mean difference in OMEs prescribed was XX (95%CI: YY-YY, p=X). The mean difference in Visual Analogue Pain Scores (VAS) and patient satisfaction are XX (95%CI: YY-YY, p=X). The absolute difference in opioid refills was XX (95%CI: YY-YY, p=X).

The results of the current study will demonstrate whether an opioid sparing approach to postoperative outpatient pain management is effective at reducing opioid consumption while adequately addressing postoperative pain in patients undergoing outpatient shoulder and knee arthroscopy. This study is novel in the field of arthroscopic surgery, and its results will help to guide appropriate postoperative analgesic management following these widely performed procedures.

Abstract. Introduction. Local anaesthetic injections are regularly used for perioperative pain relief for shoulder arthroscopies. In our practice all shoulder arthroscopies were performed under general aneasthesia supplemented by perioperative subacromial local anaesthetic injections or landmark guided axillary nerve together with suprascapular nerve injections. We compared pain relief achieved with these two methods. We hypothesized that the selective nerve blocks would provide better post operative pain relief as described in literature. Methods. We conducted a retrospective cohort study on two patient groups with 17 patients each. Group one patients received 20mls 50:50 mixture of 1% lignocaine and 0.5% chirocaine injections before and after start of procedure and group two patients received 20 mls of chirocaine around the axillary and suprascapular nerves. VAS scores were collected at 1 and 4 hours and analgesia taken during the first 24 hours was recorded. Results. No significant difference in pain scores was noted but analgesia requirements in the nerve block group were higher. Conclusion. Landmark guided nerve blocks did not show any advantage over subacromial local anaesthetic in our study. This is in contrast to published literature and we believe subacromial injections are more reliable and reproducible. Declaration of Interest.

The laterjet procedure is an important option in both primary and revision surgeries, especially in anterior shoulder instabilities that progress with glenoid bone loss. 12 patients who had a history of unsuccessful arthroscopic bankart repair and who underwent laterjet procedure in Ankara Atatürk Research and Training Hospital between 2013 and 2017 were included in the study and the patients were evaluated retrospectively. The mean age of the patients was calculated as 27.7 (range 21 to 38 years). Rowe and Walch-Duplay scores and operated shoulder (OS)-healthy shoulder (HS) range of motion (ROM) measurements were used to evaluate patients clinically and functionally. The mean follow-up time of the patients was calculated as 5.5±1.8 years.

Firstly, no dislocation history was recorded in any patient afer the laterjet procedure. The mean Rowe score was calculated as 82.5 (range 60–100). Accordingly, 8 patients had excellent result, 3 patients had good result and 1 patient had fair result. The mean Walch-Duplay score was 81.4 (range 55–100). It was determined as excellent result in 6 patients, good result in 4 patients and fair result in 2 patients. Another data, joint ROM of the OS-HS of patients are shown in the table. There was some limitation in OS compared to the HS. p<0.05 value was accepted as statistically significant. While there was a statistically significant difference in external rotation (OS:35.2º, HS:56.4º)(p=0.003), internal rotation (OS:65.7º, HS:68.1º)(p=0.008) and flexion (OS:171.2º, HS:175.9º)(p=0.012) degrees but there was no statistically significant difference in abduction degrees (OS:164.3º, HS:170.4º) (p=0.089). In radiological evaluation, partial graft resorption was detected in 1 patient, but it was asymptomatic. The osteoarthritis which is one of the complications of laterjet procedure, was not detected radiologically. There are some limitations of the study. Firstly, it is a retrospective study. Secondly, the demographic features of the patients such as age, gender, profession and dominant hand are excluded. Thirdly, the mean follow-up time is not too long. Finally, some of the scales filled in are based on the patient's declaration, which may not yield sufficient objective results.

In conclusion, the laterjet procedure is a suitable and reliable technique even for revision surgery in the treatment of anterior shoulder instability. It gives positive results in terms of shoulder stability and function. The major disadvantage was found to be the limitation of external rotation. Longer follow-up is needed for another outcomes and late complications, such as osteoarthritis.
