Outcomes of total shoulder arthroplasty in patients with prior anterior shoulder instability: minimum 5-year follow-up.

BACKGROUND: Patients with a history of anterior shoulder instability (ASI) commonly progress to glenohumeral arthritis or even dislocation arthropathy and often require total shoulder arthroplasty (TSA). The purposes of this study were to (1) report patient-reported outcomes (PROs) after TSA in patients with a history of ASI, (2) compare TSA outcomes of patients whose ASI was managed operatively vs. nonoperatively, and (3) report PROs of TSA in patients who previously underwent arthroscopic vs. open ASI management. METHODS: Patients were included if they had a history of ASI and had undergone TSA ≥5 years earlier, performed by a single surgeon, between October 2005 and January 2017. The exclusion criteria included prior rotator cuff repair, hemiarthroplasty, or glenohumeral joint infection before the index TSA procedure. Patients were separated into 2 groups: those whose ASI was previously operatively managed and those whose ASI was treated nonoperatively. This was a retrospective review of prospective collected data. Data collected was demographic, surgical and subjective. The PROs used were the American Shoulder and Elbow Surgeons score, Single Assessment Numerical Evaluation score, QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) score, and 12-item Short Form physical component score. Failure was defined as revision TSA surgery, conversion to reverse TSA, or prosthetic joint infection. Kaplan-Meier survivorship analysis was performed. RESULTS: This study included 36 patients (27 men and 9 women) with a mean age of 56.4 years (range, 18.8-72.2 years). Patients in the operative ASI group were younger than those in the nonoperative ASI group (50.6 years vs. 64.0 years, P < .001). Operative ASI patients underwent 10 open and 11 arthroscopic anterior stabilization surgical procedures prior to TSA (mean, 2 procedures; range, 1-4 procedures). TSA failure occurred in 6 of 21 patients with operative ASI (28.6%), whereas no failures occurred in the nonoperative ASI group (P = .03). Follow-up was obtained in 28 of 30 eligible patients (93%) at an average of 7.45 years (range, 5.0-13.6 years). In the collective cohort, the American Shoulder and Elbow Surgeons score, Single Assessment Numerical Evaluation score, QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) score, and 12-item Short Form physical component score significantly improved, with no differences in the postoperative PROs between the 2 groups. We found no significant differences when comparing PROs between prior open and prior arthroscopic ASI procedures or when comparing the number of prior ASI procedures. Kaplan-Meier analysis demonstrated a 79% 5-year survivorship rate in patients with prior ASI surgery and a 100% survivorship rate in nonoperatively managed ASI patients (P = .030). CONCLUSION: At mid-term follow-up, patients with a history of ASI undergoing TSA can expect continued improvement in function compared with preoperative values. However, TSA survivorship is decreased in patients with a history of ASI surgery compared with those without prior surgery.

Sub-ppm gas phase Raman spectroscopy in an anti-resonant hollow core fiber.

We demonstrate recent progress in the development of a Raman gas sensor using a single cladding ring anti-resonant hollow core micro-structured optical fiber (HC-ARF) and a low power pump source. The HC-ARF was designed specifically for low attenuation and wide bandwidth in the visible spectral region and provided low loss at both the pump wavelength (532 nm) and Stokes wavelengths up to a Raman shift of 5000 cm-1. A novel selective core pressurization scheme was also implemented to further reduce the confinement loss, improving the Raman signal enhancement by a factor of 1.9 compared to a standard fiber filling scheme. By exploiting longer lengths of fiber, direct detection of both methane and hydrogen at concentrations of 5 and 10 ppm respectively is demonstrated and a noise equivalent limit-of-detection of 0.15 ppm is calculated for methane.

Editorial Commentary: Shoulder Superior Capsular Reconstruction Graft Tensioning Between 30° and 40° of Glenohumeral Abduction Is Recommended: The Balance Beam of Superior Capsular Reconstruction.

Massive irreparable rotator cuff tears in young, active patients pose a challenging treatment dilemma. Since the relatively recent development of the superior capsular reconstruction (SCR) procedure, the technique has been increasingly used to stave off reverse total shoulder arthroplasty in this demographic. As a result of continued output of supportive literature, both biomechanically and clinically, SCR has been adopted by surgeons despite some technical aspects of the procedure not being fully elucidated. One notable topic of study is the ideal glenohumeral position in which to determine graft length and therefore graft tension. Tensioning inevitably affects glenohumeral joint kinematics, including superior humeral head translation, subacromial contact pressure, and graft healing potential. Although it is currently known that some degree of glenohumeral abduction is necessary for appropriate graft tensioning, and there are some biomechanical studies from our group and other groups that have looked at this, there is not a clinically supported position in which to measure graft length and therefore set graft tension. Well-designed biomechanical studies will serve as the foundation for what is performed clinically. On the basis of the best available evidence, tensioning the graft between 30° and 40° of glenohumeral abduction is recommended and has yielded encouraging clinical outcomes for SCR in our patients.

Editorial Commentary: Suprascapular Nerve Decompression Can Be Effective, But Should You Have the Nerve to Do It?

Isolated suprascapular neuropathy that requires surgical decompression is rare. Arthroscopic suprascapular nerve decompression is an effective treatment for correctly indicated patients, but identifying which patients would benefit from decompression is challenging. While good outcomes and low complication rates after arthroscopic suprascapular nerve decompression have been reported by expert surgeons, this procedure has potential for neurovascular injury in inexperienced hands. Given the rarity of the condition, the difficulty with accurate diagnosis, and the potential risks from surgical intervention, we believe that these patients are best treated in a tertiary referral practice.

Probing Isosteric Replacement for Immunoadjuvant Design: Bis-Aryl Triazole Trehalolipids are Mincle Agonists.

Herein, we report the modular synthesis and immunological activity of seven bis-aryl triazole trehalolipids (1a-1g) as Brartemicin analogs. The compounds comprised one or two octyloxy (C8) alkyl chains and were synthesized using the venerable CuAAc reaction between the respective aryl acetylenes and a trehalose diazide. A Mincle reporter cell assay revealed that all lipidated analogs activated Mincle. Two compounds, 1c and 1d, produced strong Mincle-dependent immune responses in vitro. The activity was dependent on the degree of alkylation and regiochemistry, with 1c and 1d showing significantly increased IL-1ß production in vitro compared to monoalkylated compounds and dialkylated compounds lacking ortho substitution. Molecular docking of 1c positioned the triazole in proximity to Arg-183, which may offer additional interactions that could explain the binding affinity for this class of ligand. These findings demonstrate the capability of triazole-linked Brartemicin analogs as Mincle-mediated Th1/Th17 vaccine adjuvants.

Inflammatory and Immunologic Contributions in Femoroacetabular Impingement Syndrome.

Femoroacetabular impingement (FAI) is one of the most common causes of labral and early cartilage damage in the nondysplastic hip. FAI is increasingly recognized as a cause for hip and groin pain in the young, active patient, and the surgical treatment of FAI with hip arthroscopy has risen exponentially. Although our understanding of FAI and the progression to degenerative osteoarthritis of the hip has historically been considered a mechanical "wear-and-tear" disease of an imperfectly shaped, aspherical, femoral head within a deep or overcovering acetabulum leading to cartilage injury, our understanding of the intrinsic pathophysiologic mechanisms underlying the development of FAI and joint degeneration of the hip remains poor. For example, many patients with FAI morphology may never develop hip pain or osteoarthritis; there remains more to discover regarding the pathophysiology of arthritis in the setting of FAI. Recent work has begun to identify a strong inflammatory and immunologic component to the FAI disease process that affects the hip synovium, labrum, and cartilage and may be detectable from peripheral clinical samples (blood and urine). This review highlights our current understanding of the inflammatory and immunologic contributions to FAI and potential therapeutic strategies to supplement and augment the surgical management of FAI.

Biomechanical Analysis Evaluating Meniscal Extrusion After Knotless Suture Anchor Fixation for Segmental Medial Meniscal Allograft Transplantation.

Background: Segmental medial meniscal allograft transplantation (MAT) has been shown to restore knee biomechanics; however, stable fixation of the transplantation is critical to avoid extrusion and maximize healing. Purpose: To evaluate the degree of meniscal extrusion and biomechanical function of segmental medial MAT performed with meniscocapsular sutures versus repair augmentation with knotless suture anchors. Study Design: Controlled laboratory study. Methods: Segmental midbody medial meniscectomy and subsequent segmental medial MAT were performed on 10 fresh-frozen cadaveric knees. The knees were then loaded in a dynamic tensile testing machine to 1000 N for 60 seconds at 0°, 30°, 60°, and 90° of flexion, and 4 conditions were tested: (1) intact, (2) segmental defect, (3) inside-out segmental repair, and (4) anchor plus inside-out segmental repair of the medial MAT. Meniscal extrusion was measured using high-fidelity ultrasound imaging. The mean contact area and the mean and peak contact pressures were assessed with submeniscal pressure-mapping sensors. Data from testing conditions were compared with 2-way repeated-measures analysis of variance, with pairwise comparison using the Bonferroni method. Results: At 90° of flexion, the segmental defect state showed a higher degree of meniscal extrusion compared with all other states (P ≤ .012). There was no difference in the degree of meniscal extrusion between the intact state and the inside-out repair or anchor plus inside-out segmental repair states at all knee flexion angles (P > .05). There was no significant difference in the mean and peak contact pressures among the 4 states at all flexion angles except that at 0° of knee flexion there was significantly lower peak contact pressure at the medial compartment after anchor plus inside-out segmental repair compared with the segmental defect state (P = .048). Conclusion: Meniscal extrusion was not significantly increased at any flexion angle after segmental resection. The addition of knotless anchors did not improve meniscal extrusion or contact pressures/area compared with capsular repair alone. The addition of knotless anchors did improve contact mechanics from the segmental defect state, but only at 0° of flexion. Clinical Relevance: The addition of knotless suture anchors to segmental meniscal transplantation increased stabilization of the meniscus at full extension compared with repair with sutures alone. This increased stabilization may lead to better long-term outcomes.

Response Bias for Press Ganey Ambulatory Surgery Surveys after Knee Surgery.

The Press Ganey Ambulatory Surgery (PGAS) survey is an emerging tool used to capture patient satisfaction after elective surgery. Evaluating patient satisfaction is important; however, quality improvement (QI) surveys used to capture the patient experience may be subject to nonresponse bias. An orthopaedic registry was used to retrospectively identify patients who underwent ambulatory knee surgery from June 2015 to December 2019. Multivariable logistic regression was performed to identify independent predictors of PGAS survey nonresponse and response. In the cohort of 1,161 patients, 142 (12.2%) completed the PGAS survey. Multiple logistic regression demonstrated that male sex, Black race, not living with a caretaker, student or unemployment status, and worse preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) fatigue were predictors of nonresponse. The results of this study highlight the presence of nonresponse bias in the PGAS survey after elective knee surgery.

Long-Term Visual Outcomes in Neovascular Age-Related Macular Degeneration Eyes With Baseline Macular Atrophy on Anti-Vascular Endothelial Growth Factor Treatment.

BACKGROUND AND OBJECTIVE: This study explores the connection between macular atrophy (MA) status at baseline and best visual acuity (BVA) after 5 to 7 years of anti-vascular endothelial growth factor (anti-VEGF) injections on eyes with neovascular age-related macular degeneration (nAMD). PATIENTS AND METHODS: This retrospective study included patients with neovascular age-related macular degeneration receiving anti-VEGF injections at least twice-yearly for 5+ years at Cole Eye Institute. Analyses of variance and linear regressions explored the connection between MA status, baseline MA intensity, and 5-year BVA change. RESULTS: Of 223 included patients, 5-year BVA change was not statistically significant between MA status groups or from baseline. The population's average 7-year BVA change was -6.3 Early Treatment Diabetic Retinopathy Study letters. Type and frequency of anti-VEGF injections were comparable between MA status groups (P > 0.05). CONCLUSION: Regardless of MA status, 5- and 7-year BVA change lacked clinical relevance. If receiving regular treatment for 5+ years, patients with baseline MA achieve comparable visual outcomes to those without MA, with similar treatment and visit burdens.

Use of Computed Tomography in the Evaluation of Anterior Shoulder Instability: Possible Effect on Surgical Management.

BACKGROUND: Glenoid bone loss is a critical factor in the management of anterior shoulder instability (ASI). Computed tomography (CT) is often considered the gold standard to evaluate glenoid bone loss, but it is associated with negative factors such as radiation. Thus, interest exists as to when orthopaedic surgeons need a CT scan to guide decision-making when treating ASI. PURPOSE: To determine whether information gained from a shoulder CT scan alters orthopaedic surgeons' management plan for ASI and, secondarily, to determine whether surgeon- and patient-specific factors affect whether a CT scan changes treatment and which clinical factors are most important in surgical decision-making. STUDY DESIGN: Cross-sectional study. METHODS: A questionnaire composed of 24 ASI vignettes was administered to Herodicus Society members, American Shoulder and Elbow Surgeons Neer Circle members, and sports medicine fellowship-trained orthopaedic surgeons. Participants chose their recommended surgical treatment from the options of arthroscopic Bankart repair, open Bankart repair, bony reconstruction procedure, or other based on patient history, radiographs, and magnetic resonance imaging. Participants were then shown CT images and asked whether their treatment plan changed and, if not, whether the CT scan was not necessary or had reinforced their decision. Generalized linear mixed-effects logistic regression modeling was performed to assess the influence of vignette and respondent characteristics on treatment decisions. RESULTS: A total of 74 orthopaedic surgeons completed the survey; 96% were fellowship trained (sports medicine, 50%; shoulder and elbow surgery, 41%), and 66% practiced in academic settings. CT imaging did not change the selected treatment strategy in 75.6% of responses. In cases when management did not change, surgeons reported that the CT scan reinforced their decision in 53.4% of responses and was not necessary for decision-making in 22.2% of responses. Decision-making was more likely to be changed after CT in male patients and those with off-track lesions. CONCLUSION: Information gained from a CT scan did not alter treatment decision-making in three-quarters of vignettes among surgeons experienced in the management of ASI. The finding that CT scans did alter the treatment plan in nearly a quarter of cases is not insignificant, and it appears that in patients with borderline glenoid track status and few other risk factors for recurrence after arthroscopic stabilization, CT imaging is more likely to change management.

Anterior Closing-Wedge High Tibial Slope-Correcting Osteotomy Using Patient-Specific Preoperative Planning Software for Failed Anterior Cruciate Ligament Reconstruction.

Failure of anterior cruciate ligament reconstruction (ACLR) remains a challenging problem. Recently, the effect of increased posterior tibial slope has been identified as a risk factor for ACLR failure. In cases with increased posterior tibial slope, an anterior closing wedge, slope-correcting high tibial osteotomy can be used as a robust adjunct to revision ACLR. In this Technical Note, we demonstrate our preferred method for isolated sagittal plane correction following multiple failed ACLRs with an anterior closing-wedge high tibial osteotomy technique using 3-dimensional patient-specific instrumentation. Through correction of the angular deformity and restoration of the defined sagittal slope via the use of advanced 3-dimensional patient-specific instrumentation, this technique fosters an accurate, favorable mechanical environment to prevent recurrent instability of the knee joint.

PROMIS Depression and Anxiety in shoulder surgery patients.

AIMS: The purpose of this study was to assess the prevalence of depression and anxiety symptoms in patients undergoing shoulder surgery using the National Institutes of Health (NIH) Patient-Reported Outcomes Measurement Information System (PROMIS) Depression and Anxiety computer adaptive tests, and to determine the factors associated with more severe symptoms. Additionally, we sought to determine whether PROMIS Depression and Anxiety were associated with functional outcomes after shoulder surgery. METHODS: This was a retrospective analysis of 293 patients from an urban population who underwent elective shoulder surgery from 2015 to 2018. Survey questionnaires included preoperative and two-year postoperative data. Bivariate analysis was used to identify associations and multivariable analysis was used to control for confounding variables. RESULTS: Mean two-year PROMIS Depression and Anxiety scores significantly improved from preoperative scores, with a greater improvement observed in PROMIS Anxiety. Worse PROMIS Depression and Anxiety scores were also significantly correlated with worse PROMIS Physical Function (PF) and American Shoulder and Elbow Surgeons scores (ASES). After controlling for confounding variables, worse PROMIS Depression was an independent predictor of worse PROMIS PF, while worse PROMIS Anxiety was an independent predictor of worse PROMIS PF and ASES scores. CONCLUSION: Mean two-year PROMIS Depression and Anxiety scores improved after elective shoulder surgery and several patient characteristics were associated with these scores. Worse functional outcomes were associated with worse PROMIS Depression and Anxiety; however, more severe two-year PROMIS Anxiety was the strongest predictor of worse functional outcomes.

Arthroscopic Treatment of Snapping Scapula Syndrome With Scapulothoracic Bursectomy and Partial Scapulectomy.

Snapping scapula syndrome (SSS) is a painful and debilitating condition that occurs as a result of disruption of normal scapulothoracic articulation and inflammation of numerous soft tissue and bursal structures that function to facilitate scapulothoracic motion. Historically, when nonoperative management of SSS failed, patients progressed to open surgical management. However, as arthroscopic techniques have evolved, the condition has been increasingly treated arthroscopically because of the minimally invasive nature, periscapular muscle-preserving approach with decreased risk to surrounding neurovascular structures, better intraoperative visualization, and quicker patient recovery and rehabilitation. The objective of this Technical Note is to describe our arthroscopic approach for the management of SSS using two portals to complete a scapulothoracic bursectomy and partial scapulectomy of the superomedial scapula. Level of Evidence: Level I: shoulder.

Patient Perception of Being "Completely Better" After Anterior Cruciate Ligament Reconstruction.

BACKGROUND: Contextualizing patient-reported outcomes (PROs) by defining clinically relevant differences is important. Considering that anterior cruciate ligament reconstruction (ACLR) ideally results in the restoration of normal knee function, an assessment of patients' perception of being "completely better" (CB) may be of particular value. PURPOSE: The purpose of this study was to assess the prevalence and characteristics of patients who self-report a CB status after ACLR. Additionally, we aimed to determine whether PROs were associated with a CB status after ACLR as well as to determine CB status thresholds for 2-year and change in values. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: We retrospectively analyzed data from an orthopaedic registry at a single institution. Patients were administered the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF), PROMIS Pain Interference (PI), and International Knee Documentation Committee (IKDC) Subjective Knee Form preoperatively and at 2 years after ACLR. Additionally, patients completed a CB anchor question at 2 years after ACLR. Thresholds for 2-year and change in PRO scores associated with achieving a CB status were identified with 90% specificity. RESULTS: Overall, 95 of the 136 patients (69.9%) considered their condition to be CB at 2 years after surgery. The 2-year and change in PROMIS PF, PROMIS PI, and IKDC scores were significantly better in the CB group than in the non-CB group. Thresholds associated with a CB status for 2-year PROMIS PF, PROMIS PI, and IKDC scores were more reliable than those for changes in scores and were ≥63, ≤44, and ≥80, respectively. Thresholds for the change in PROMIS PF, PROMIS PI, and IKDC scores were ≥19, ≤-16, and ≥44, respectively. CONCLUSION: The majority of patients reported that they were CB at 2 years after ACLR. This study may serve as a reference for orthopaedic surgeons and researchers when considering outcomes after ACLR.

Impact of prior anterior instability on shoulder arthroplasty outcomes: a systematic review.

Background: Anterior shoulder instability (ASI) is a frequently encountered pathology. Patients with a history of ASI have an increased rate of developing glenohumeral osteoarthritis and becoming candidates for shoulder arthroplasty. This systematic review aims to synthesize outcomes for patients undergoing shoulder arthroplasty with a history of ASI. Methods: A comprehensive literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using PubMed, Embase, OVID Medline, Scopus, CINAHL, Web of Science, and Cochrane databases for studies evaluating the impact of prior ASI on total shoulder arthroplasty (TSA), reverse TSA, and/or hemiarthroplasty outcomes, with a minimum follow-up of 12 months. Studies were graded by level of evidence and data concerning patient demographics and outcomes were extracted. Results: Sixteen articles met the inclusion criteria, including 596 patients (413 male, 181 female). The average age of the control and prior ASI groups were 57.5 and 57.0 years, respectively. Overall, 251 patients were treated operatively, 132 nonoperatively, and 213 were controls without a history of prior ASI. Shoulder arthroplasty techniques included TSA (436 shoulders), reverse TSA (130 shoulders), and hemiarthroplasty (14 shoulders). Prior anterior stabilization management included soft tissue repair, bony augmentation, and nonoperative treatment. Almost all studies reported no significant difference in subjective and functional arthroplasty outcomes between control and prior ASI groups, or between patients with prior ASI treated nonoperatively vs. surgically. Conclusion: Shoulder arthroplasty in the setting of prior ASI results in improved subjective and functional outcome scores that are comparable to patients without a history of instability.

Preoperative Opioid Use in Patients Undergoing Common Hand Surgeries.

BACKGROUND: The objectives of this study were to determine the baseline patient characteristics associated with preoperative opioid use and to establish whether preoperative opioid use is associated with baseline patient-reported outcome measures in patients undergoing common hand surgeries. METHODS: Patients undergoing common hand surgeries from 2015 to 2018 were retrospectively reviewed from a prospective orthopedic registry at a single academic institution. Medical records were reviewed to determine whether patients were opioid users versus nonusers. On enrollment in the registry, patients completed 6 Patient-Reported Outcomes Measurement Information System (PROMIS) domains (Physical Function, Pain Interference, Fatigue, Social Satisfaction, Anxiety, and Depression), the Brief Michigan Hand Questionnaire (BMHQ), a surgical expectations questionnaire, and Numeric Pain Scale (NPS). Statistical analysis included multivariable regression to determine whether preoperative opioid use was associated with patient characteristics and preoperative scores on patient-reported outcome measures. RESULTS: After controlling for covariates, an analysis of 353 patients (opioid users, n = 122; nonusers, n = 231) showed that preoperative opioid use was associated with higher American Society of Anesthesiologists class (odds ratio [OR], 2.88), current smoking (OR, 1.91), and lower body mass index (OR, 0.95). Preoperative opioid use was also associated with significantly worse baseline PROMIS scores across 6 domains, lower BMHQ scores, and NPS hand scores. CONCLUSIONS: Preoperative opioid use is common in hand surgery patients with a rate of 35%. Preoperative opioid use is associated with multiple baseline patient characteristics and is predictive of worse baseline scores on patient-reported outcome measures. Future studies should determine whether such associations persist in the postoperative setting between opioid users and nonusers.

Clinical Outcomes of Pectoralis Major Tendon Repair with and without Platelet-Rich Plasma.

Purpose: To assess clinical outcomes following pectoralis major tendon (PMT) repairs and to compare outcomes of PMT repairs augmented with and without leukocyte-poor platelet-rich plasma (LP-PRP). Methods: A retrospective review of prospectively collected data was performed of patients who underwent a PMT repair from May 2007 to June 2019 with a minimum of 2-year follow-up. Exclusion criteria included revision PMT repair, PMT reconstruction, and concomitant repair of another glenohumeral tendon/ligament. LP-PRP was injected surrounding the PMT repair before wound closure. Patient-reported outcome (PRO) data were collected preoperatively and evaluated at final follow-up using the American Shoulder and Elbow Surgeons Score (ASES), Single Assessment Numeric Evaluation Score (SANE), Quick Disabilities of the Arm, Shoulder and Hand Score (QuickDASH), and Short Form 12 physical component summary (SF-12 PCS), patient satisfaction with outcomes. Results: Twenty-three men (mean age, 38.6 years; range, 20.5-64.3 years) were included in the final analysis. Mean time from injury to surgery was 30 days (range, 3-123 days). Follow-up was obtained for 16 of 23 patients (70%) at a mean of 5.1 years (range 2.0-13.0 years). Significant improvement in PROs was observed (ASES: 59.0 → 92.4, P = .008; SANE: 44.4 → 85.9, P = .018; QuickDASH: 44.4 → 8.5, P = .018; and SF-12 PCS: 42.5 → 52.6, P = .008). Median satisfaction was 9 of 10 (range, 6-10). Patients receiving LP-PRP had superior ASES (99.6 vs 83.0, P = .001), SANE (94.8 vs 74.6, P = .005), QuickDASH (0.24 vs 19.1, P = .001), and patient satisfaction (10 vs 9, P = .037) scores compared with those without PRP. PROs were unchanged based on chronicity, mechanism of injury, or tear location. One patient had revision surgery at 3.4 years due to adhesions. Conclusions: PMT repair produces improved PROs at final follow-up when compared with preoperative values. Level of Evidence: Level III, retrospective comparative therapeutic trial.

Opioid Prescribing Habits for Common Arthroscopic Procedures in Opioid Naïve Patients.

BACKGROUND: With the opioid epidemic and the increasing number of opioid-related deaths, there is growing awareness in the medical community regarding the dangers of opioid overprescription. As a result, there is a willingness among physicians to abandon old norms and adopt new data-driven prescribing practices. PURPOSE: To demonstrate patient-reported consumption data of opioid medications after anterior cruciate ligament (ACL) reconstructions (ACLRs), knee arthroscopies, and rotator cuff repairs to provide data-driven guidelines for prescribing opioids after these procedures. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Included in the study were 168 patients who underwent an ACLR, knee arthroscopy, or arthroscopic rotator cuff repair over a 17-month period. Patients were excluded if they had an opioid allergy, had preexisting opioid use, had an acute postoperative complication requiring further surgery, required hospitalization, exhibited drug-seeking behaviors, or were lost to follow-up. Medical records were reviewed to determine the number of opioid pills prescribed and the number of pills taken postoperatively. Prescribing was standardized in that 15 hydrocodone/acetaminophen pills (5/325 mg) were prescribed for all knee arthroscopy procedures and 40 hydrocodone/acetaminophen pills were prescribed for all ACL and rotator cuff procedures. The mean number of pills consumed and percentage of prescribed pills taken were analyzed in association with specific procedures and patient demographics. RESULTS: Overall, the mean (±SD) reported opioid consumption overall was 13.5 ± 13.0 pills, with a utilization rate of 45.6% of the prescription. The mean reported opioid consumption for ACLRs, knee arthroscopies, and rotator cuff repairs was 19.1 ± 15.4, 7.2 ± 5.4, and 17.2 ± 14.3 pills, respectively (P < .001). This represented a utilization rate of 48%, 47%, and 41%, respectively. CONCLUSION: This study provides important information regarding opioid utilization after common arthroscopic procedures. For ACLRs, knee arthroscopies, and rotator cuff repairs, by respectively prescribing 20, 10, and 20 pills postoperatively, the amount of unused medications would decrease by 60%, 47%, and 64%, respectively. We recommend prescribing no more than 20, 10, and 20 hydrocodone/acetaminophen pills (5/325 mg) for ACLRs, knee arthroscopies, and arthroscopic rotator cuff repairs, respectively.

Difference in Resident Versus Attending Perspective of Competency and Autonomy During Arthroscopic Rotator Cuff Repairs.

A noted deficiency in orthopaedic resident education is a lack of intraoperative autonomy; however, no studies exist evaluating this issue. The purpose of this study was to determine whether there is a difference between resident and attending perception of resident competency and autonomy during arthroscopic rotator cuff repairs and whether increased perceived competency leads to more autonomy. METHODS: This study included 21 orthopaedic residents and 7 attendings from a single residency program. A survey was developed that included the previously validated Ottawa Surgical Competency Operating Room Evaluation (O-SCORE) and implemented novel arthroscopic rotator cuff repair questions concerning 5 key procedural steps determined by attendings. The survey assessed resident and attending perception of percent opportunity given and percent completed of each step and whether the resident could complete the surgery independently. Paired comparisons were conducted using the Wilcoxon signed-rank test. Agreement between residents and attendings was calculated using a linear-weighted Gwet's AC2. A secondary analysis investigated resident perception of autonomy stratified by attending perception of competency using Kruskal-Wallis tests. RESULTS: One hundred forty-two surveys were completed over one academic year. Residents reported a 4-point higher median O-SCORE (34) than attendings (30; p < 0.01; agreement = 0.63). Residents perceived less opportunity compared with attendings, with a median opportunity to complete each step of 54% vs. 70% (p < 0.01; agreement = 0.39). Residents also perceived lower percent completed of the key steps compared with attendings, with medians of 52% vs. 61% (p < 0.01; agreement = 0.37). Resident perceived opportunity increased with higher attending reported O-SCOREs (p < 0.01) and percent completion of the key steps (p < 0.01). No statistically significant increase in perceived opportunity was observed the with post-graduate year (PGY) level (p = 0.35). DISCUSSION: This study demonstrated a significant difference in perception between residents and attendings regarding resident competency and autonomy during arthroscopic rotator cuff repairs. It also demonstrated that with increasing attending perception of competency, there was an increasing resident perception of autonomy, but there was no statistically significant difference of perceived autonomy based on the PGY-level.

Predictors of postoperative pain using PROMIS pain interference two-years following knee surgery.

INTRODUCTION: The purpose of this study was to identify preoperative factors associated with worse PROMIS Pain Interference (PI) two years following knee surgery. METHODS: Participants completed surveys preoperatively and two years postoperatively. Data collected included demographics, medical history, and multiple patient-reported outcomes measures, including PROMIS PI. RESULTS: After controlling for confounders, lower income, smoking, worse PROMIS Anxiety, worse Numeric Pain Score body pain, and worse Marx Activity Rating Scale were independent predictors for worse PROMIS PI two years after surgery. CONCLUSION: Worse PROMIS PI two years after elective knee surgery is associated with multiple socio-demographic patient identifiers.
