Open versus arthroscopic treatment of the rheumatoid elbow arthritis: a comparison of complications at two years utilizing a nationally representative database.

PURPOSE: Symptomatic rheumatoid arthritis (RA) can be addressed surgically with open procedures or elbow arthroscopy. Previous studies comparing outcomes of open to arthroscopic arthrolysis for the management of RA did not utilize a large database study. The aim was to compare demographics and two-year complications, in RA patients undergoing open or arthroscopic elbow arthrolysis. METHODS: A retrospective, cohort study was performed utilizing a private, nationwide, all-payer database. We queried the database to identify patients undergoing open (n = 578) or arthroscopic (n = 379) arthrolysis for elbow RA. The primary goal of the study was to compare complications at two-years. Categorical variables were assessed utilizing the chi-squared test; while, continuous variables were analyzed using the Student's t-test. Multivariable logistic regression was performed to assess risk factors for infection following open or arthroscopic arthrolysis. RESULTS: RA patients undergoing open elbow arthrolysis were older (55 vs. 49 years, p < 0.001), predominately female (61.6% vs 60.9%, p = 0.895), and likely to have chronic kidney disease (20.4 vs. 12.9%), and DM (45.2 vs. 32.2%) (both p < 0.005). Open elbow arthrolysis was also associated with higher rates of infection (31.7 vs. 4.7%) and wound complications (26.8 vs. 3.4%) (both p = 0.001). Nerve injury rates were found to be similar (8.3 vs. 9.0%, p = 0.81). On multivariable logistic regression, open elbow procedures were associated with the highest risk for infection (OR: 8.43). CONCLUSIONS: Patients undergoing open arthrolysis for RA were at a higher risk of infection and wound complications compared to arthroscopic arthrolysis utilizing a nationally representative database. While there appears to be a difference in outcomes following these two procedures, higher level evidence is needed to draw more definitive conclusions. LEVEL OF EVIDENCE: Retrospective, Level III.

Validation of Temperature Sensors to Monitor Thermoplastic Splint Wear in Hand Surgery Patients.

BACKGROUND: The aim of this study was to validate the use of temperature sensors to accurately measure thermoplastic volar forearm splint wear in a healthy cohort of volunteers using 5- and 15-minute temperature measurement intervals. METHODS: A prospective diagnostic study was performed to evaluate the diagnostic accuracy of temperature sensors in monitoring splint wear in 8 healthy volunteers between December 2022 and June 2023. Temperature sensors were molded into thermoplastic volar forearm splints. Volunteers who were familiar with the study aims were asked to keep an exact log of the time spent wearing the splint ("actual wear time"). Sensors recorded temperatures every 5 or 15 minutes, and separate algorithms were developed to determine the sensor-detected wear time compared with the actual wear time as the gold standard. The algorithms were then externally validated with the total population. RESULTS: The 5-minute and 15-minute algorithms demonstrated excellent sensitivity (99.1% vs 96.6%), specificity (99.9% vs 99.9%), positive (99.4% vs 99.5%) and negative (99.9% vs 99.3%) predictive value, and diagnostic accuracy (99.8% vs 99.3%), respectively. The 5-minute algorithm recorded 99.5% of the total splint hours, whereas the 15-minute algorithm recorded 96.1%. There was no significant difference between the actual time per wear session (5.4 ± 2.7 hours) and the time estimated by the 5-minute algorithm (5.4 ± 2.6 hours; P = .40), but there was a significant difference for the 15-minute algorithm (5.2 ± 2.6 hours; P < .001). CONCLUSION: Temperature sensors can be used to accurately monitor thermoplastic volar forearm splint wear. LEVEL OF EVIDENCE: Diagnostic II.

Preoperative Corticosteroid Injections Within 4 Weeks of Arthroscopic Shoulder Procedures Are Associated With Increased Postoperative Infection Rates.

PURPOSE: To refine the understanding of the effect of timing of corticosteroid injections (CSIs) and shoulder arthroscopy on postoperative infection. METHODS: An insurance database was used to determine all patients who underwent shoulder arthroscopy for a 5-year period with an associated preoperative ipsilateral corticosteroid injection. Patients were stratified into cohorts based on timing of preoperative CSI: (1) 0-<2 weeks, (2) 2-<4 weeks, (3) 4-<6 weeks, and (4) 6-<8 weeks. Patients were pooled to include all patients who had a CSI less than 4 weeks and those longer than 4 weeks. A cohort of patients who never had a corticosteroid injection before undergoing arthroscopy were used as a control. All patients had a follow-up of 2 years. Multivariable regression analyses were performed using R Studio with significance defined as P < .05. RESULTS: Multivariate logistic regression showed a greater odds ratio (OR) for postoperative infection in patients who received CSI 0-<2 weeks before shoulder arthroscopy at 90 days (3.10, 95% confidence interval [CI] 1.62-5.57, P < .001), 1 year (2.51, 95% CI 1.46-4.12, P < .001), and 2 years (2.08, 95% CI 1.27-3.28, P = .002) compared with the control group. Patients who received CSI 2-<4 weeks before shoulder arthroscopy had greater OR for infection at 90 days (2.26, 95% CI 1.28-3.83, P = .03), 1 year (1.82, 95% CI 1.13-2,82, P = .01), and 2 years (1.62, 95% CI 1.10-2.47, P = .012). Patients who received CSI after 4 weeks had similar ORs of infection at 90 days (OR 1.15, 95% CI 0.78-1.69, P = .48) 1 year (OR 1.18, 95% CI 0.85-1.63 P = .33), and 2 years (OR 1.09, 95% CI 0.83-1.42, P = .54), compared with the control cohort. CONCLUSIONS: The present study shows the postoperative infection risk is greatest when CSIs are given within 2 weeks of shoulder arthroscopy, whereas CSIs given within 2-<4 weeks also portend increased risk, albeit to a lesser degree. The risk of postoperative infection is not significantly increased when CSIs are given more than 1 month before surgery. LEVEL OF EVIDENCE: Level III, retrospective comparative, prognosis study.

Hand Fractures-Management and the Complications That Inevitably Occur: Metacarpal Fractures.

Metacarpal fractures are among the most common hand fractures. To properly manage these injuries, surgeons must understand the anatomy, biomechanics, clinical assessment, surgical and nonsurgical treatment options, and potential complications. Metacarpal head fractures often require surgical treatment to restore the joint surface by using a variety of techniques. Metacarpal neck fractures are usually stable injuries that do not require surgical intervention, but surgeons must know when surgical intervention is indicated. Fractures of the metacarpal shaft can be treated surgically and nonsurgically and may be associated with large bone defects or soft-tissue injuries that require careful consideration. Finally, fractures involving the carpometacarpal joints must be promptly managed to avoid long-term complications, potentially requiring salvage procedures.

Proximal Interphalangeal Joint Fractures.

Multiple fracture patterns can occur around the proximal interphalangeal joint and require surgeons to have a thorough understanding of the anatomy, clinical and radiographic examination, common fracture patterns, surgical and nonsurgical treatment options, and potential complications. Proximal phalangeal condylar fractures are typically managed surgically, because even nondisplaced fractures have a propensity for displacement. Middle phalangeal base fractures most commonly present as a volar lip fracture with or without dorsal subluxation or dislocation. Treatment options include extension block splinting or pinning, transarticular pinning, open reduction and internal fixation, external fixation, volar plate arthroplasty, and hemihamate arthroplasty. Less common fractures include dorsal lip fractures with or without volar subluxation or dislocation (the central slip fracture), lateral plateau impaction or avulsion injuries, and pilon fractures. The main goals in the management of middle phalangeal base fractures are to restore articular congruency and initial early range of motion, which are more important than obtaining an anatomic reduction.

Pediatric Phalanx Fractures.

Phalangeal fractures are extremely common in the pediatric and adolescent populations. The incidence of phalangeal fractures peaks in children ages 10 to 14 years, corresponding to the age in which children begin contact sports. Younger children are more likely to experience crush injuries, whereas older children often sustain phalangeal fractures during sports. The physis is particularly susceptible to fracture because of the biomechanically weak nature of the physis compared with the surrounding ligaments and bone. Phalangeal fractures are identified through a thorough physical examination and are subsequently confirmed with radiographic evaluation. Management of pediatric phalangeal fractures is dependent on the age of the child, the severity of the injury, and the degree of fracture displacement. Nondisplaced fractures are often managed nonsurgically with immobilization, whereas unstable, displaced fractures may require surgery, which is often a closed rather than open reduction and percutaneous pinning.

Does timing matter? The effect of preoperative smoking cessation on the risk of infection or revision following rotator cuff repair.

BACKGROUND: Nicotine in tobacco products is known to impair bone and tendon healing, and smoking has been associated with an increased rate of retear and reoperation following rotator cuff repair (RCR). Although smoking is known to increase the risk of failure following RCR, former smoking status and the timing of preoperative smoking cessation have not previously been investigated. METHODS: A national all-payer database was queried for patients undergoing RCR between 2010 and 2020. Patients were stratified into 5 mutually exclusive groups according to smoking history: (1) never smokers (n = 50,000), (2) current smokers (n = 28,291), (3) former smokers with smoking cessation 3-6 months preoperatively (n = 34,513), (4) former smokers with smoking cessation 6-12 months preoperatively (n = 786), and (5) former smokers with smoking cessation >12 months preoperatively (n = 1399). The risks of postoperative infection and revision surgery were assessed at 90 days, 1 year, and 2 years following surgery. Multivariate logistic regressions were used to isolate and evaluate risk factors for postoperative complications. RESULTS: The 90-day rate of infection following RCR was 0.28% in never smokers compared with 0.51% in current smokers and 0.52% in former smokers who quit smoking 3-6 months prior to surgery (P < .001). Multivariate logistic regression identified smoking (odds ratio [OR], 1.49; P < .001) and smoking cessation 3-6 months prior to surgery (OR, 1.56; P < .001) as risk factors for 90-day infection. The elevated risk in these groups persisted at 1 and 2 years postoperatively. However, smoking cessation >6 months prior to surgery was not associated with a significant elevation in infection risk. In addition, smoking was associated with an elevated 90-day revision risk (OR, 1.22; P = .038), as was smoking cessation between 3 and 6 months prior to surgery (OR, 1.19; P = .048). The elevated risk in these groups persisted at 1 and 2 years postoperatively. Smoking cessation >6 months prior to surgery was not associated with a statistically significant elevation in revision risk. CONCLUSION: Current smokers and former smokers who quit smoking within 6 months of RCR are at an elevated risk of postoperative infection and revision surgery at 90 days, 1 year, and 2 years postoperatively compared with never smokers. Former smokers who quit >6 months prior to RCR are not at a detectably elevated risk of infection or revision surgery compared with those who have never smoked.

Acromion morphology is associated with glenoid bone loss in posterior glenohumeral instability.

BACKGROUND: The acromion morphology in a shoulder with posterior instability differs from that of a shoulder without glenohumeral instability. Specifically, the acromion with a flatter sagittal tilt, greater posterior acromial height, and less posterior coverage is associated with posterior instability. However, the association between acromion morphology and glenoid bone loss (GBL) in the setting of posterior glenohumeral instability has not previously been investigated. The purpose of this study was to determine whether acromial morphology influences the extent or pattern of posterior GBL in a cohort of patients with posterior glenohumeral instability. METHODS: This multicenter retrospective study identified 89 shoulders with unidirectional posterior glenohumeral instability. Total area GBL was measured using the best-fit circle method on magnetic resonance imaging (MRI). Shoulders were divided into 3 groups: (1) no GBL (n = 30), (2) GBL 0%-13.5% (n = 45), or (3) GBL ≥13.5% (n = 14). Acromion measurements were performed on MRI and included acromial tilt, posterior acromial height, anterior acromial coverage, and posterior acromial coverage. RESULTS: Patients without GBL had a steeper acromial tilt (58.5° ± 1.4°) compared with those with 0%-13.5% GBL (64.3° ± 1.5°) or GBL ≥13.5% (67.7° ± 1.8°) (P = .004). Patients without GBL also had greater posterior coverage (65.4° ± 1.7°) compared with those with GBL (60.3° ± 1.4°) (P = .015). Posterior acromion height was not significantly different among groups. CONCLUSION: The results demonstrate that an acromion with a flatter sagittal tilt and less posterior coverage is associated with GBL in the setting of posterior glenohumeral instability. This is important to consider as posterior GBL has been identified as a risk factor for failure of posterior soft tissue-stabilizing procedures.

Glenoid Bone Loss Pattern in Patients With Posterior Instability Versus Anterior Instability: A Matched Cohort Study.

Background: The pattern of glenoid bone loss (GBL) in anterior glenohumeral instability is well described. It was recognized recently that posterior GBL after instability has a posteroinferior pattern. Purpose/Hypothesis: The purpose of this study was to compare GBL patterns in a matched cohort of patients with anterior versus posterior glenohumeral instability. The hypothesis was that the GBL pattern in posterior instability would be more inferior than the GBL pattern in anterior instability. Study Design: Cohort study; Level of evidence, 3. Methods: In this multicenter retrospective study, 28 patients with posterior instability were matched with 28 patients with anterior instability by age, sex and number of instability events. GBL location was defined using a clockface model. Obliquity was defined as the angle between the long axis of the glenoid and a line tangent to the GBL. Superior and inferior GBL were measured as areas and defined relative to the equator. The primary outcome was the 2-dimensional characterization of posterior versus anterior GBL. The secondary outcome was a comparison of the posterior GBL patterns in traumatic and atraumatic instability mechanisms in an expanded cohort of 42 patients. Results: The mean age of the matched cohorts (n = 56) was 25.2 ± 9.87 years. The median obliquity of GBL was 27.53° (interquartile range [IQR], 18.83°-47.38°) in the posterior cohort and 9.28° (IQR, 6.68°-15.75°) in the anterior cohort (P < .001). The mean superior-to-inferior bone loss ratio was 0.48 ± 0.51 in the posterior cohort and 0.80 ± 0.55 (P = .032) in the anterior cohort. In the expanded posterior instability cohort (n = 42), patients with traumatic injury mechanism (n = 22), had a similar GBL obliquity compared to patients with an atraumatic injury mechanism (n = 20) (mean, 27.73° [95% CI, 20.26°-35.20°] vs 32.20° [95% CI, 21.27°-43.14°], respectively) (P = .49). Conclusion: Posterior GBL occurred more inferiorly and at an increased obliquity compared with anterior GBL. This pattern is consistent for traumatic and atraumatic posterior GBL. Bone loss along the equator may not be the most reliable predictor of posterior instability, and critical bone loss may be reached more rapidly than a model of loss along the equator may predict.

Increased actual sling wear is associated with better early patient-reported and image-based outcomes after shoulder surgery.

BACKGROUND: Prior studies have failed to show differences in functional outcomes for patient-reported sling use after rotator cuff repair. Temperature-sensing devices are used to more accurately measure brace adherence. The purposes of this study were to quantify actual sling adherence and its predictors and to establish whether increased sling adherence is associated with improved functional and image-based outcomes. METHODS: We performed a prospective cohort study of 65 patients undergoing shoulder surgery requiring ≥4 weeks of postoperative sling use. Temperature-sensing devices were implanted in the slings to monitor sling adherence. Patient-reported sling adherence was determined from a questionnaire. Patients were considered 80% adherent if they wore the sling 16 h/d (112 h/week) when 20 h/d was prescribed. The primary outcomes were patient-reported and actual sling adherence, patient-reported outcomes (American Shoulder and Elbow Surgeons score and visual analog scale pain score) within 12 months postoperatively, and image-based failure based on ultrasound or radiography at 6 weeks and 1 year postoperatively. RESULTS: Patient-reported sling adherence was highly sensitive (82.8%), was poorly specific (28.6%), had low accuracy (53.1%), and was weakly correlated with actual sling adherence (r = 0.32, P = .009). On multivariable logistic regression analysis, male patients were 91% less likely than female patients to be adherent with sling use (odds ratio, 0.09; 95% confidence interval [CI], 0.02-0.42; P = .002). Additionally, obese and morbidly obese patients were 88% (95% CI, 0.02-0.84; P = .033) and 98% (95% CI, 0.002-0.27; P = .003), respectively, less likely than non-obese patients to adhere to sling wear postoperatively. After we controlled for surgical procedure, visual analog scale pain scores were significantly better at 6 weeks (ß = -1.47; 95% CI, -2.88 to -0.05; P = .04) and 3 months (ß = -1.68; 95% CI, -3.28 to -0.08; P = .04) if patients adhered to sling wear. A receiver operating characteristic curve showed that 13.6 hours and 15.4 hours of daily sling wear optimized image-based outcomes at 6 weeks (failure rate, 0% vs. 16%; P = .01) and 1 year (failure rate, 3% vs. 28%; P = .008) postoperatively, respectively. CONCLUSION: The results of this study demonstrate that patient-reported sling adherence is unreliable, adherence can be predicted by female sex and lower body mass index, and increased sling adherence is associated with improved early pain scores and image-based outcomes. These data can help inform future studies using postoperative sling protocols as patient-reported sling adherence is not an accurate method to assess sling use.

Does needle penetration of the shoulder joint prior to arthroscopy increase infection risk? The effect of preoperative magnetic resonance arthrogram or corticosteroid injection.

BACKGROUND: Prior literature has associated preoperative corticosteroid shoulder injection (CSI) with infection following shoulder surgery. A recent study found an equally elevated risk of total knee arthroplasty infection with preoperative injection of either CSI or hyaluronic acid. The implication is that violation of a joint prior to surgery, even in the absence of corticosteroid, may pose an elevated risk of infection following orthopedic surgery. The aim of the present study was to determine whether violation of the shoulder joint for magnetic resonance arthrogram (MRA) poses an elevated risk of infection following shoulder arthroscopy, and to compare this risk to that introduced by preoperative CSI. METHODS: A national, all-payer database was queried to identify patients undergoing shoulder arthroscopy between January 2015 and October 2020. Patients were stratified into the following groups: (1) no CSI or MRA within 6 months of surgery (n = 5000), (2) CSI within 2 weeks of surgery (n = 1055), (3) CSI between 2 and 4 weeks prior to surgery (n = 2575), (4) MRA within 2 weeks of surgery (n = 414), and (5) MRA between 2 and 4 weeks prior to surgery (n = 1138). Postoperative infection (septic shoulder or surgical site infection) was analyzed at 90 days, 1 year, and 2 years, postoperatively. Multivariable logistic regression analysis controlled for differences among groups. RESULTS: MRA within 2 weeks prior to shoulder surgery was associated with an increased risk of infection at 1 year (odds ratio [OR], 2.17; P = .007), while MRA 2-4 weeks preceding surgery was not associated with an increased risk of postoperative infection at any time point. By comparison, CSI within 2 weeks prior to surgery was associated with an increased risk of postoperative infection at 90 days (OR, 1.72; P = .022), 1 year (OR, 1.65; P = .005), and 2 years (OR, 1.63; P = .002) following surgery. Similarly, CSI 2-4 weeks prior to surgery was associated with an increased risk of postoperative infection at 90 days (OR, 1.83; P < .001), 1 year (OR, 1.62; P < .001), and 2 years (OR, 1.79; P < .001). CONCLUSION: Preoperative CSI within 4 weeks of shoulder arthroscopy elevates the risk of postoperative infection. Needle arthrotomy for shoulder MRA elevates the risk of infection in a more limited fashion. Avoidance of MRA within 2 weeks of shoulder arthroscopy may mitigate postoperative infection risk. Additionally, the association between preoperative CSI and postoperative infection may be more attributed to medication profile than to needle arthrotomy.

The Effect of Patients' Understanding of Sling Necessity and Home Assistance on Sling Wear After Shoulder Surgery.

BACKGROUND: Perioperative education and socioeconomic factors influence patient behavior. Recent evidence has suggested that sling compliance is associated with improved outcomes after shoulder surgery; it is important to investigate factors that influence sling compliance. PURPOSE: To determine the associations between postoperative sling wear and patients' understanding of sling necessity, postoperative home assistance, and social deprivation. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: A total of 66 patients were prospectively enrolled from 2018 to 2020 if they were ≥18 years of age and undergoing shoulder surgery requiring a sling for at least 1 month postoperatively. Sling wear was measured using a temperature-sensing device. At 6 weeks postoperatively, patients' understanding for sling necessity was determined by their response to a question on the Medical Adherence Measure questionnaire, "Why did you have to wear a shoulder sling?" The Patient Understanding Grading Scale (PUGS) was developed to quantify patient responses. PUGS was graded 1 to 3, with grade 1 corresponding to the least technical knowledge. Patient characteristics, social deprivation (Area Deprivation Index [ADI]), and home assistance were additionally analyzed. RESULTS: There were no significant differences in baseline characteristics between patients when stratified by PUGS grade. Multivariable linear regression analysis for total hours of sling wear per week showed that patients with PUGS grade 2 (ß, 48.2 hours; P = .007) and grade 3 (ß, 59.5 hours; P = .003) wore their slings significantly more than grade 1 patients. Patients with home assistance had significantly greater day hours (73.5 ± 33.0 vs 44.0 ± 24.5 hours; P = .037) of sling wear per week, but there was no difference in night sling hours. Patients older than 60 years wore their slings significantly more, while men and those with a higher body mass index (BMI) wore their slings significantly less. ADI was not significantly associated with sling wear. CONCLUSION: This study demonstrates that patients with greater understanding for sling necessity, those with home assistance, and patients >60 years have greater sling wear, while male patients and those with a higher BMI have lower sling compliance. ADI was not a significant contributor.

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.

Preoperative Factors Associated with Press Ganey Patient Satisfaction Scores after Anterior Cruciate Ligament Reconstruction.

Patient satisfaction is increasingly used as a metric to evaluate the quality of healthcare services and to determine hospital and physician compensation. The aim of this study was to identify preoperative factors associated with Press Ganey Ambulatory Surgery (PGAS) satisfaction scores, and to evaluate the effect of each PGAS domain score on the total PGAS score variability in patients undergoing anterior cruciate ligament reconstruction (ACLR). A review of a Press Ganey (PG) database at a single center was performed for patients undergoing ACLR between 2015 and 2019. Ninety-nine patients completed the PGAS survey and 54 also completed preoperative demographic and patient-reported outcome measures (PROMs) for an orthopaedic registry. PGAS scores were calculated and bivariate analysis was performed. Multivariable linear regression determined the effect of each of the six PGAS domains on the total PGAS score variability. In the total cohort of 99 patients, no factors were significantly associated with the total PGAS score or any domain scores. For the 54 patients who also participated in the orthopaedic registry, none of the preoperative PROMs were significantly correlated with total PGAS score. However, having a college degree (89 vs. 95 or 97 points; p = 0.02) and continuous femoral nerve catheter (92 vs. 100 points; p = 0.04) was associated with lower personal issue domain scores, while patients with a greater number of prior surgeries had worse registration domain scores (ρ = -0.27; p = 0.049). For the entire cohort, the registration and facility domains contributed the most variability to the total PGAS score, while the physician domain contributed the least. Few preoperative factors are associated with PGAS scores, and total PGAS scores do not significantly correlate with baseline PROMs. Surgeons may have limited ability to improve their PGAS scores given most of the variability in total scores stems from systemic aspects of the patient experience.

Risk of Avascular Necrosis with The Modified Dunn Procedure in SCFE Patients: A Meta-Analysis.

In situ stabilization is a widely accepted treatment for slipped capital femoral epiphysis (SCFE) despite risks of avascular necrosis (AVN) and femoroacetabular impingement (FAI). The modified Dunn procedure with surgical hip dislocation attempts to maintain epiphyseal perfusion and allows anatomic epiphyseal repositioning, theoretically reducing AVN and FAI risks. We systematically evaluated the literature, elucidating overall and stability-stratified rates of AVN following the modified Dunn procedure, and revision rates in non-AVN patients. Using Ovid and MEDLINE (PubMed), studies involving the modified Dunn procedure were evaluated for age, stability, preoperative slip (Southwick) angle, ROM at follow-up, outcome metrics, and revisions. Utilizing a random effect model of proportions, we determined overall and stability-stratified AVN rates, and revision rates in patients without AVN.673 patients (688 SCFEs) who underwent modified Dunn procedure were included. Overall AVN rate was 14.3% with a 95% Confidence Interval (CI) of 9.3 to 20.2%. AVN rate in stable slips was 10.9% (95% CI: 6.0 to 17.1%) and 19.9% (95% CI: 12.8% to 28.1%) in unstable slips. Revision rate in non-AVN patients was 13.3% (95% CI: 8.3% to 19.2%). Fixation failures occurred following K-wire or small-caliber (<6.5 mm) screw fixation. Overall mean Harris Hip Score (HHS) was excellent (>90 points). Mean HHS was 98.9 points (range of means: 86 to 99 points) in stable cases, and 90.5 points (range of means: 73 to 98 points) in unstable cases. Patients undergoing modified Dunn procedure had excellent clinical outcomes and low incidences of AVN. Further studies are needed to determine if modified Dunn osteotomy with surgical hip dislocation is a viable alternative to in situ pinning for treatment of severe SCFE.

Correlation of Press Ganey Scores With Early Patient Satisfaction After Anterior Cruciate Ligament Reconstruction.

Background: Patient satisfaction metrics are commonly used to assess the quality of health care and affect reimbursement. The Press Ganey Ambulatory Surgery (PGAS) is a satisfaction survey that has emerged as a prominent quality assessment tool; however, no data exist on whether PGAS scores correlate with early postsurgical satisfaction during the PGAS survey administration period in patients who underwent anterior cruciate ligament reconstruction (ACLR). Purpose: To determine if PGAS scores correlate with measures of satisfaction and patient-reported outcomes (PROs) at 2 weeks postoperatively in ACLR patients. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: A retrospective review of patients who underwent ACLR at a single institution was performed. Patients who completed the PGAS survey and PROs at 2 weeks postoperatively were included in the study. Surgical satisfaction was measured with the Surgical Satisfaction Questionnaire (SSQ-8), and PROs included 6 Patient-Reported Outcomes Measurement Information System domains. Bivariate analysis between PGAS and PRO scores was conducted using the Spearman rank correlation coefficient (r S). Results: Of the 716 patients who received the PGAS survey after ACLR, 81 patients completed the survey, and 39 patients also completed PROs and were included in the study. Total converted (mean scaled score) and "top box" (percentages of questions with highest rating selected) PGAS scores showed no significant correlations with the SSQ-8 (r S =-0.24; P = .14). There were no significant correlations between SSQ-8 and PGAS domain scores except for a negative correlation with Facility domain top box scores (r S =-0.33; P = .04), meaning that patients with higher surgical satisfaction had lower PGAS Facility scores. Total PGAS (converted and top box scores) and PGAS domain scores showed no significant correlation with any of the other PROs. Conclusion: PGAS scores showed no significant positive correlation with surgical satisfaction, function, pain, mental health, activity, or expectations of surgery in patients 2 weeks after ACLR. This suggests little to no relationship between PGAS score and surgical satisfaction in the early recovery period after ACLR.

Impact of Preoperative Opioid Use on 2-Year Patient-Reported Outcomes in Knee Surgery Patients.

The objectives of this study are to assess perioperative opioid use in patients undergoing knee surgery and to examine the relationship between preoperative opioid use and 2-year postoperative patient-reported outcomes (PROs). We hypothesized that preoperative opioid use and, more specifically, higher quantities of preoperative opioid use would be associated with worse PROs in knee surgery patients. We studied 192 patients undergoing knee surgery at a single urban institution. Patients completed multiple PRO measures preoperatively and 2-year postoperatively, including six patient-reported outcomes measurement information system (PROMIS) domains; the International Knee Documentation Committee (IKDC) questionnaire, numeric pain scale (NPS) scores for the operative knee and the rest of the body, Marx's knee activity rating scale, Tegner's activity scale, International Physical Activity Questionnaire, as well as measures of met expectations, overall improvement, and overall satisfaction. Total morphine equivalents (TMEs) were calculated from a regional prescription monitoring program. Eighty patients (41.7%) filled an opioid prescription preoperatively, and refill TMEs were significantly higher in this subpopulation. Opioid use was associated with unemployment, government insurance, smoking, depression, history of prior surgery, higher body mass index, greater comorbidities, and lower treatment expectations. Preoperative opioid use was associated with significantly worse 2-year scores on most PROs, including PROMIS physical function, pain interference, fatigue, social satisfaction, IKDC, NPS for the knee and rest of the body, and Marx's and Tegner's scales. There was a significant dose-dependent association between greater preoperative TMEs and worse scores for PROMIS physical function, pain interference, fatigue, social satisfaction, NPS body, and Marx's and Tegner's scales. Multivariable analysis confirmed that any preoperative opioid use, but not quantity of TMEs, was an independent predictor of worse 2-year scores for function, activity, and knee pain. Preoperative opioid use and TMEs were neither independent predictors of met expectations, satisfaction, patient-perceived improvement, nor improvement on any PROs. Our findings demonstrate that preoperative opioid use is associated with clinically relevant worse patient-reported knee function and pain after knee surgery.

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.

Discharge Opioid Prescribing Patterns in an Academic Orthopaedic Setting: Level of Training and Subspecialty Patterns.

INTRODUCTION: Despite increased research on opioids in the orthopaedic literature, little is known of the prescribing practices of orthopaedic providers based on their level of training. The purpose of this study was to describe the discharge opioid prescribing patterns of orthopaedic providers, stratifying by level of training and orthopaedic subspecialty, within a single medical system. METHODS: A retrospective review of orthopaedic surgical encounters was performed over a 1-year period for adults who received a discharge opioid prescription. Patient demographics and prescriber characteristics were collected, including the provider's level of training (attending, fellow, resident, physician assistant [PA], and nurse practitioner [NP]) and surgical subspecialty. Junior residents were postgraduate year 1 to 3, whereas senior residents/fellows were postgraduate year 4 to 6. Discharge opioids were converted to milligram morphine equivalents (MMEs). Overprescribing was defined as a prescribing more than a seven-day supply or >45 MMEs per day. Multivariable linear regression analysis determined the factors associated with discharge MMEs, whereas logistic regression determined the factors associated with overprescribing opioids. RESULTS: Of the 3,786 patients reviewed, 1,500 met the criteria for inclusion in the study. The greatest proportion of opioid prescriptions was written by junior residents (33.9%), followed by NPs (30.1%), PAs (24.1%), senior residents/fellows (10.6%), and attendings (1.2%). Compared with junior residents, senior residents prescribed -59.4 MMEs, NPs prescribed +104 MMEs, and attendings prescribed +168 MMEs (P < 0.05), whereas PAs prescribed similar amounts (P > 0.05). Orthopaedic subspecialty was also predictive of discharge MMEs (P < 0.05). Senior residents and attendings were more likely to prescribe more than seven days of opioids (P < 0.05), whereas NPs and PAs were more likely to prescribe >45 MMEs per day (P < 0.05). DISCUSSION: This study demonstrates significant variability in opioid prescribing practices according to provider level of training and subspecialty. National guidelines for opioid prescribing practices and educational programs may help reduce such variability. LEVEL OF EVIDENCE: Level III, retrospective cohort study.
