Preoperative opioid use is associated with worse preoperative patient-reported outcomes in hip arthroscopy patients.

OBJECTIVES: The purpose of this study was to define the rate of preoperative opioid use among patients undergoing hip arthroscopy, ascertain which clinical factors are associated with opioid use, and assess the effect of preoperative opioid usage on preoperative patient-reported outcome (PRO) measures. METHODS: A single institution orthopedic registry was retrospectively analyzed for patients undergoing hip arthroscopy for femoroacetabular impingement (FAI) syndrome with or without labral tear between 2015 and 2022. Patients completed Patient-Reported Outcomes Measurement Information System (PROMIS) in six domains, Numeric Pain Scores (NPS), and Musculoskeletal Outcomes Data Evaluation and Management System expectations domain preoperatively. Patients' charts were reviewed to determine demographic factors and identify any active opioid prescription within 6 weeks before surgery. Bivariate analysis was used to determine associations between preoperative opioid use and baseline PROs. Statistically significant bivariate associations were further tested by multivariate analysis to determine independent predictors. RESULTS: A total of 123 patients were included (age 39.7 â€‹± â€‹12.0 years; 87 females; body mass index 27.4 â€‹± â€‹5.7 kg/m2). There were 21 patients (17%) using opioids preoperatively. Prior orthopedic or other surgery and lower education level were associated with preoperative opioid use. Patients with preoperative opioid use scored statistically significantly worse compared with those without preoperative opioid use on baseline PROMIS Physical Function (38.6 vs 40.5, p â€‹= â€‹0.01), Pain Interference (65.9 vs 60.2, p â€‹= â€‹0.001), Fatigue (60.7 vs 51.6, p â€‹= â€‹0.005), Social Satisfaction (38.2 vs 43.2, p â€‹= â€‹0.007), and Depression (54.2 vs 48.8, p â€‹= â€‹0.01). Preoperative opioid use was also associated with statistically significantly worse preoperative NPS for both the operative hip (6.3 vs 4.6, p â€‹= â€‹0.003) and whole body (3.0 vs 1.4, p â€‹= â€‹0.008). Preoperative opioid use was an independent predictor of worse baseline PROMIS Pain Interference, Fatigue, Social Satisfaction, and NPS for the operative hip. CONCLUSION: Patients using opioids preoperatively had worse baseline PROs for physical function, pain, social satisfaction, and depression than those not using opioids preoperatively. When controlling for confounding variables, preoperative opioid use was independently predictive of worse baseline pain, fatigue, and social satisfaction. LEVEL OF EVIDENCE: Level III, prognostic study.

Biomechanical Comparison of Four- versus Six-Strand Transosseous Suture Repair for Patellar Tendon Rupture.

BACKGROUND: Surgical repair is indicated for patellar tendon ruptures that result in loss of knee extensor mechanism function. However, biomechanical studies report conflicting results when comparing transosseous suture versus suture anchor repair techniques. This discrepancy may be due to inconsistencies in experimental design as these studies use various numbers of suture strands. Therefore, the main objective of this study is to compare the ultimate load of four- versus six-strand transosseous suture repair. Secondary objectives are to compare gap formation after cyclical loading and mode of failure. METHODS: Six pairs of fresh-frozen cadaveric specimen were randomly allocated to either four- or six-strand transosseous suture repair. Specimen underwent preconditioning cyclical loading and then load to failure. RESULTS: The six-strand repair had a significantly higher maximum load to failure compared with the four-strand repair (mean difference = 319.3 N [57.9%], p = 0.03). There was no significant difference in gap length after cyclical loading or at max load. There were no significant differences in mode of failure. CONCLUSION: Utilizing a six-stand transosseous patella tendon repair construct with one additional suture increases overall construct strength by over 50% compared with a four-strand construct.

Patient-Reported Outcome Measurement Information System Depression and Anxiety in Elective Knee Surgery Patients.

Mental health has been shown to play an important role in patient-reported outcomes (PRO); however, there is a general lack of literature describing patient-reported outcome measurement information system (PROMIS) depression and anxiety computer adaptive tests in elective knee surgery patients. The purpose of our study was to assess the prevalence of depression and anxiety symptoms before and after elective knee surgery and to determine whether these symptoms influence postoperative functional outcomes. An institutional review board-approved prospective orthopaedic registry was retrospectively queried for patients undergoing elective knee surgery from June 2015 to November 2018. Electronic surveys collecting patient demographic information and PROs were administered pre- and postoperatively. Of the 663 patients that completed baseline questionnaires, 466 completed 2-year follow-up (70.3%). PROs included PROMIS depression, PROMIS anxiety, International Knee Documentation Committee Subjective Knee Form (IKDC), and PROMIS physical function (PF). Wilcoxon rank sum and Spearman's rank order correlation were utilized to determine associations between variables. Multivariable analysis was used to control for confounding variables. Average PROMIS depression and anxiety scores significantly improved 2 years after surgery. PROMIS depression and anxiety scores significantly correlated with each other. PROMIS depression and anxiety scores significantly correlated with PROMIS PF and IKDC scores. After controlling for confounders on multivariable analysis, worse 2-year PROMIS anxiety was predictive of less functional improvement and worse 2-year PF and IKDC, while worse 2-year PROMIS depression was predictive of less improvement in IKDC. This study confirms the important relationship between mental health and functional outcomes. Given that psychiatric comorbidities are potentially modifiable with treatment, proper recognition could potentially lead to better orthopaedic outcomes. In addition, the prevalence of depression and anxiety symptoms postoperatively, as documented by PROMIS computer adaptive tests, may act as a barrier to achieving optimal functional outcomes after elective knee surgery. LEVEL OF EVIDENCE: Level III.

PROMIS cluster analysis predicts two-year outcomes in knee surgery patients.

Aims & objectives: Meaningful clinical interpretation of orthopaedic patient-reported outcome scores remains challenging. Grouping scores may be more meaningful than individual score analysis. The purpose of this study was to determine if grouping knee surgery patients into four preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) clusters would have prognostic value for two-year postoperative outcomes. Materials & methods: 488 of 697 (70%) patients undergoing elective knee surgery at a single urban institution were enrolled in an orthopaedic registry and completed two-year follow up. Patients were administered questionnaires for PROMIS, International Knee Documentation Committee Score (IKDC), Marx Activity Rating Scale (MARS), and Surgical Satisfaction (SSQ-8). A k-means cluster analysis was performed to identify preoperative PROMIS clusters. Chi-square or Kruskal-Wallis tests were conducted for bivariate analyses. Least-squares multiple linear regression models were performed to identify if cluster group was an independent predictor. Results: Cluster analysis revealed four clusters of patients. Psychological distress was most significant in determining classification. More impaired clusters were associated with higher rates of arthroplasty, African American race, preoperative opioid use, lower income, higher comorbidity index, and other sociodemographic and operative factors. Worse preoperative cluster status was associated with higher chance of achieving minimally clinically important change (MCID) on all metrics except PROMIS Pain Interference (PI), IKDC, and MARS. Multivariable analysis confirmed better preoperative cluster as predictive of better PROMIS Physical Function (PF), PI, IKDC scores, and satisfaction. Worse preoperative cluster was predictive of greater improvement on PF and PI but not IKDC. Conclusion: Preoperative PROMIS clusters have prognostic value in predicting outcomes for knee surgery patients. Better preoperative cluster function predicts superior outcomes. While worse preoperative cluster predicts worse outcome, all clusters still significantly improve, so worse preoperative cluster is not a contraindication to surgery.

Perioperative Opioid Use in Anterior Cruciate Ligament Reconstruction Patients.

Anterior cruciate ligament reconstruction (ACLR) is one of the most commonly performed outpatient orthopaedic procedures, yet there is little data about perioperative opioid prescribing practices. The purposes of this study were to quantify the perioperative opioid prescriptions filled by patients who underwent ACLR and to identify factors associated with greater postoperative opioid use. Patients who underwent ACLR at a single institution between June 2015 and May 2017 were studied using a regional prescription monitoring database to identify all preoperative and postoperative outpatient opioid prescriptions up to 2 years postoperatively. The number of morphine milligram equivalents of each opioid was calculated to determine total morphine milligram equivalents (TMEs) filled preoperatively, at discharge, and refilled postoperatively. Patients who refilled an opioid prescription postoperatively were compared with those who did not. Ninety-nine of 269 (36.8%) total patients refilled an opioid prescription postoperatively. Thirty-three patients (12.3%) required a refill after 2 weeks postoperatively, and no patients refilled after 21 months postoperatively. Fifty-seven patients (21%) received an opioid prescription in the 2 years following surgery that was unrelated to their ACL reconstruction. Increased age, higher body mass index (BMI), government insurance, current or prior tobacco use history, preoperative opioid use, and greater number of medical comorbidities were significantly associated with refilling a prescription opioid. Higher BMI and government insurance were independent predictors of refilling. Higher preoperative TMEs and surgeon were independent predictor of greater refill TMEs. In the opioid-naïve subgroup of 177 patients, only higher BMI was a predictor of refilling, and only greater comorbidities was a predictor of greater refill TMEs. The results demonstrate that preoperative opioid use was associated with postoperative opioid refills and higher refill TMEs in a dose-dependent fashion. A higher percentage of patients received an opioid prescription for reasons unrelated to the ACL reconstruction than refilled a prescription after the first 2 weeks postoperatively.

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.

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.

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 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.

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

The purposes of this study were to identify the patient characteristics associated with refilling a postoperative opioid prescription after knee surgery and to determine whether refilling opioids is associated with 2-year patient-reported outcomes. We hypothesized that postoperative refill of opioids would be associated with worse 2-year patient-reported outcomes. We studied 192 patients undergoing knee surgery at a single urban academic institution. Patients completed multiple patient-reported outcome measures preoperatively and 2 years postoperatively, including six Patient-Reported Outcomes Measurement Information System (PROMIS) domains, the International Knee Documentation Committee (IKDC) questionnaire, numeric pain scale scores for the operative knee and the rest of the body, Marx Activity Rating Scale, as well as measures of met expectations, improvement, and satisfaction. Total morphine equivalents (TMEs) were calculated from a regional prescription monitoring program. Patients who refilled a postoperative opioid prescription were compared with those who did not, and TMEs were calculated for those who refilled (Refill TMEs). One hundred twenty-nine patients (67%) refilled at least one postoperative opioid prescription. Black race, older age, higher average body mass index (BMI), smoking, greater medical comorbidities, preoperative opioid use, lower income, government insurance, and knee arthroplasty were associated with refilling opioids. Greater Refill TMEs was associated with black or white race, older age, higher average BMI, smoking, greater medical comorbidities, preoperative opioid use, government insurance, and unemployment. Refilling opioids and greater Refill TMEs were associated with worse postoperative scores on most patient-reported outcome measures 2 years after knee surgery. However, refilling opioids and greater Refill TMEs did not have a significant association with improvement after surgery. Multivariable analysis controlling for potential confounding variables confirmed that greater postoperative Refill TMEs independently predicted worse 2-year PROMIS Physical Function, 2-year PROMIS Pain Interference, and 2-year IKDC knee function scores. Postoperative refill of opioids was associated with worse 2-year patient-reported outcomes in a dose-dependent fashion. These findings reinforce the importance of counseling patients regarding opioid use and optimizing opioid-sparing pain management postoperatively.

Predictors of two-year patient satisfaction following elective knee surgery.

BACKGROUND: Patient satisfaction metrics are increasingly being utilized as tools to evaluate the quality of healthcare and affect reimbursements. The objectives of this study were to (1) identify factors associated with two-year patient satisfaction after elective knee surgery, (2) compare the Surgical Satisfaction Questionnaire-8 (SSQ-8) and a numeric satisfaction scale (NSS), and (3) determine if two-year patient satisfaction can be predicted based on preoperative factors. METHODS: A total of 365 patients undergoing elective knee surgery at a single center were administered questionnaires to assess demographics, medical history, and various patient-reported outcomes preoperatively and at two years postoperatively. Patient satisfaction was measured at two years postoperatively with SSQ-8 and NSS. Bivariate and multivariate statistical analyses were performed to identify significant associations and independent predictors of satisfaction. RESULTS: SSQ-8 and NSS scores were significantly correlated (rs = 0.68, P < 0.0001). Lower SSQ-8 and NSS scores were associated with black race, higher BMI, more comorbidities, unemployment, smoking, higher ASA score, and greater Met Expectations (P < 0.05). Better scores on patient-based outcome measures and better improvement from baseline were significantly correlated with higher satisfaction on both SSQ-8 and NSS. Multivariable analysis identified greater Met Expectations and higher two-year Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference scores as independent predictors of greater SSQ-8 scores (adjusted r2 = .52). Greater Met Expectations and better two-year PROMIS Social Satisfaction scores were independent predictors of NSS score (adjusted r2 = .41). In contrast, when only preoperative variables were considered, the multivariable regression model accounted for only 14% of the variance in SSQ-8 and 6% of the variance in NSS. CONCLUSION: While there are multiple preoperative factors that are associated with two-year patient satisfaction after knee surgery, those factors contribute relatively little to satisfaction. Meeting expectations and better patient-based outcomes at two years are more important.

An accurate method of measuring shoulder sling compliance: a validation study.

BACKGROUND: The effect of postoperative shoulder sling compliance on surgical outcomes is unknown. The goal was to determine an accurate method to measure sling compliance. We compared volunteer recorded sling wear time with temperature-based sensors to monitor sling compliance. METHODS: Data loggers sutured at three locations measured heat generated in 15-minute intervals. Slings wearers logged sling wear to accurately cross-reference with temperature sensors. Secondary experiments analyzed whether surrounding ambient temperature can be discerned from actual sling wear. We created an algorithm to describe actual sling wear time as a function of heat recorded and calculated percent wear accuracy. RESULTS: The modified sling was worn for 172 h. The algorithm modeled sling on/off times by analyzing cutoff temperatures. Diagnostic accuracy was >99 % for the three locations, with no statistically significant differences among them. Compared with sling wear, ambient temperature took longer to reach critical temperature values determined by the algorithm, helping distinguish compliance from false positives. CONCLUSIONS: The described algorithm can effectively quantify shoulder sling wear time based on heat-generated sensor readings. False positives from ambient temperature are minimal. This measurement method could be used to study the relationship between postoperative sling use and functional outcomes after shoulder surgery.

Impact of pre-operative recreational marijuana use on outcomes two years after orthopaedic surgery.

PURPOSE: The purpose of this study was to investigate the relationship between recreational marijuana use and patient-reported outcomes two years after orthopaedic surgery. We hypothesized that pre-operative recreational marijuana use would be associated with less pain, better function, and better mental health measures two years after orthopaedic surgery. METHODS: Patients were retrospectively analyzed from a prospective orthopaedic registry at a single urban institution. A total of 1710 patients completed the pre-operative assessment and 1103 patients (64.5%) completed the two-year follow-up questionnaires. The cohort was then divided into two groups based on reported preoperative recreational marijuana usage, and statistical analysis was performed to determine if marijuana use was associated with two-year outcomes. Multivariable analysis was used to control for confounding variables. RESULTS: Marijuana use was reported by 47 (4.3%) patients. Significantly worse scores for two-year PROMIS Anxiety (53.2 vs. 49.2, p = 0.005), PROMIS Depression (51.1 vs. 46.5, p = 0.001), Met Expectations (63.1 vs. 74.4, p = 0.024), Surgical Satisfaction Questionnaire-8 (71.7 vs. 80.4, p = 0.005), and Numeric Satisfaction Scale (75.6 vs. 83.1, p = 0.041) were associated with marijuana use. Marijuana users also had less improvement of Numeric Pain Scores at the operative site (- 1.8 vs. - 2.7, p = 0.037) and greater decrease in Marx activity scores for lower extremities (- 12.3 vs. - 3.9, p = 0.024). Marijuana use was not an independent predictor of any outcome measure in the multivariable analysis. CONCLUSION: Marijuana use was associated with worse mental health scores, lower activity level, less pain relief, and worse satisfaction two years after orthopaedic surgery. However, after controlling for confounding variables, marijuana use was not predictive of any two-year outcome measure. STUDY DESIGN: Cross-sectional study.

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.

Outcomes of Partial Meniscectomy in Obese Patients: A Systematic Review and Meta-Analysis.

OBJECTIVE: Arthroscopic partial meniscectomy (APM) is one of the most commonly performed surgical procedures. However, the indications for APM are controversial and obese patients may have worse outcomes. This study's primary purpose was to investigate differences in outcome after APM associated with elevated body mass index (BMI). Secondary objectives included differences in pathophysiology, surgical complications/failures, or osteoarthritis development. DESIGN: MEDLINE, EMBASE, and OVID databases were systematically searched for eligible studies reporting on APM outcomes at a minimum of 1 year postoperatively. Studies that did not include BMI categorization were excluded. Meta-analysis was conducted with random-effects modeling where data from at least 2 studies was available. RESULTS: A total of 16 articles were included. Overweight/obese BMI was associated with worse preoperative Lysholm (mean difference, -6.06 [95% CI, -11.70 to -0.42]) and visual analogue scale pain scores (0.43 [0.07 to 0.79]). Worse postoperative normalized knee-specific patient-reported outcome scores were also associated with obese BMI (-4.57 [-5.33 to -3.81]). There were no significant differences in clinical improvement or osteoarthritis progression among BMI groups. Two studies found higher complication/failure rates, 3 articles associated medial meniscus posterior root tears, and 1 article found differences in gene transcript expression with increased BMI. CONCLUSIONS: Obesity is associated with worse knee function after APM, and patients with elevated BMI have worse preoperative knee pain and function. However, there is no difference in amount of improvement between elevated and normal BMI patients. Further prospective research is necessary to determine the comparative effectiveness of APM in patients with elevated BMI.

Preoperative Expectations of Patients Undergoing Knee Surgery.

There is limited validated data regarding the relationship between preoperative expectations and patient-reported outcomes (PROs) in patients undergoing knee surgery. The purpose of this study was to (1) assess the preoperative expectations of patients undergoing knee surgery and (2) determine the relationship between preoperative patient demographics, PROs, and preoperative patient expectations. We hypothesized that younger patients with worse function and worse general health status would have greater expectations of knee surgery. We analyzed data from 399 patients undergoing knee surgery at an urban academic medical center. We utilized the Musculoskeletal Outcomes Data Evaluation and Management System to measure preoperative expectations. Multiple legacy PRO measures were recorded, as well as the new Patient-Reported Outcomes Measurement Information Systems (PROMIS) Computer Adaptive Testing. Nonparametric statistical analyses were performed to determine significance. Overall, patients undergoing knee surgery had high expectations, with a mean of 88.0 (95% confidence interval [CI], 86.7-89.3) and median of 91.7 (95% CI, 89.2-94.3). Greater preoperative expectations of knee surgery were associated with higher income, surgically naïve knee, lower Charlson Comorbidity Index, better PROMIS Depression and Anxiety scores, greater Marx knee activity scores, and lower total body pain (p < 0.05). Preoperative expectations of patients undergoing knee surgery are associated with a history of prior knee surgery, income, general and mental health, activity, and pain. Expectations were also found to be associated with PRO measures of function and psychological well-being. These findings may have implications for patient education and shared decision-making preoperatively. The level of evidence for the study is IV.

Predictors of early postoperative pain interference following orthopaedic surgery.

INTRODUCTION: Despite the increasing incidence of orthopaedic surgeries, there is a lack of data reporting on patient experience and recovery following surgery. As such, there is a need to better characterize the natural history of pain interference (PI) after orthopaedic surgery to better manage patients' expectations and recovery. PURPOSE: To identify factors associated with greater pain interference two weeks following orthopaedic surgery. METHODS: All patients undergoing elective outpatient orthopaedic surgery at a single urban academic institution were evaluated preoperatively from August 2016 to March 2018. Patients completed a baseline assessment consisting of demographic information, PROMIS computer adaptive testing in 6 domains including Pain Interference (PI), Physical Function, Social Satisfaction, Fatigue, Anxiety, and Depression. Two weeks following surgery, patients completed the same questionnaires along with assessments of Improvement and Satisfaction. Bivariate and multivariable regression analyses were performed. Categorical data was compared with ANOVA and continuous data was compared with Spearman's correlation coefficient (rs). RESULTS: 435 patients (age = 41.1 ± 15.7, 47% female) were studied. Mean PI was 60.1 ± 7.0 prior to surgery and 61.7 ± 7.6 at 2 weeks postoperative. Worse 2 week PROMIS PI was associated with lower extremity surgery, prior surgery on the joint, preoperative opioid use, depression, lower income, lower education, and higher ASA score (p < 0.05). Better 2 week PROMIS PI was correlated with better baseline and better 2 week scores on all outcome measures. Multivariable analysis demonstrated that lower extremity surgery, worse preoperative pain scores, and worse preoperative pain interference were independent predictors of worse pain interference after surgery. CONCLUSION: Early postoperative pain interference is associated with function, demographic, and psychosocial factors.

Capsular thinning on magnetic resonance arthrography is associated with intra-operative hip joint laxity in women.

Hip microinstability is a recognized cause of hip pain in young patients. Intra-operative evaluation is used to confirm the diagnosis, but limited data exist associating magnetic resonance arthrography (MRA) findings with hip microinstability. To determine if a difference exists in the thickness of the anterior joint capsule and/or the width of the anterior joint recess on MRA in hip arthroscopy patients with and without an intra-operative diagnosis of hip laxity. Sixty-two hip arthroscopy patients were included in the study. Two musculoskeletal radiologists blinded to surgical results reviewed the MRAs for two previously described findings: (i) anterior joint capsule thinning; (ii) widening of the anterior joint recess distal to the zona orbicularis. Operative reports were reviewed for the diagnosis of joint laxity. In all patients with and without intra-operative laxity, there were no significant differences with either MRA measurement. However, twenty-six of 27 patients with intra-operative laxity were women compared with 11 of 35 patients without laxity (P < 0.001). In subgroup analysis of women, the intra-operative laxity group had a higher rate of capsular thinning compared with the non-laxity group (85% versus 45%; P = 0.01). A 82% of women with capsular thinning also had intra-operative laxity, compared with 40% without capsular thinning (P = 0.01). There were no differences regarding the width of the anterior joint recess. In this study, there was an association between capsular thinning and intra-operative laxity in female patients. Measuring anterior capsule thickness on a pre-operative MRA may be useful for the diagnosis of hip microinstability.

Preoperative expectations and early postoperative met expectations of extremity orthopaedic surgery.

BACKGROUND: Preoperative patient expectations and met expectations are likely associated with the outcome of treatment. However, there is a lack of data regarding the preoperative expectations and early postoperative met expectations of patients undergoing extremity orthopaedic surgery. The purpose of this study was to identify the predictors of early postoperative met expectations in a cohort of patients undergoing extremity orthopaedic surgery and to assess the relationship between patient expectations and patient-reported outcome (PRO) measures. We hypothesized that patients with higher preoperative expectation scores and higher postoperative met expectation scores would have better early postoperative outcomes. METHODS: Four hundred thirty-five patients age seventeen and older who underwent extremity orthopaedic surgery at one institution were prospectively enrolled in this study. Each patient completed a preoperative questionnaire that included an assessment of demographics, pain, function, general health, treatment expectations, activity level, and Patient-Reported Outcome Measurement Information System (PROMIS) computer adaptive testing. Expectations were evaluated using the Expectations Domain of the Musculoskeletal Outcomes Data Evaluation and Management System (MODEMS) questionnaire. Patients completed a follow-up questionnaire two weeks after surgery that also assessed MODEMS met expectations and satisfaction (Surgical Satisfaction Questionnaire (SSQ-8)). RESULTS: The mean preoperative expectation score was 86.95 ± 16.59, and the mean postoperative met expectation score was 55.02 ± 27.63 (0-100 scale with 100 representing the highest level of expectations). Greater met expectations were significantly associated with white race (p = 0.025), college degree (p = 0.011), and higher income (p = 0.002). Greater met expectations were also significantly associated with greater postoperative physical function, social satisfaction, activity level, and subjective improvement, as well as lower pain interference, joint pain, body pain, fatigue, anxiety, and depression (p < 0.01 for each). Multivariable analysis results found that less postoperative joint pain and greater postoperative social satisfaction, improvement, and physical function were all significant independent predictors of greater met expectations at two weeks postoperative (p < 0.01 for each). CONCLUSION: Greater preoperative expectations are associated with better activity and less pain two weeks after surgery. Met expectations of extremity orthopaedic surgery were associated with postoperative physical function, social satisfaction, activity, pain, anxiety, depression, and subjective improvement. These results may have implications for preoperative counseling and risk factor modification.
