RESUMO
BACKGROUND: Bundled payment programs for total joint arthroplasty (TJA) have become popular among both private and public payers. Because these programs provide surgeons with financial incentives to decrease costs through reconciliation payments, there is an advantage to identifying and emulating cost-efficient surgeons. The objective of this study was to utilize the Centers for Medicare and Medicaid Services (CMS) Quality Payment Program (QPP) in combination with institutional data to identify cost-efficient surgeons within our region and, subsequently, identify cost-saving practice patterns. METHODS: Data was obtained from the CMS QPP for total knee arthroplasty (TKA) and total hip arthroplasty (THA) surgeons within a large metropolitan area from January 2019 to December 2021. A simple linear regression determined the relationship between surgical volume and cost-efficiency. Internal practice financial data determined whether patients of identified surgeons differed with respect to x-ray visits, physical therapy visits, out-of-pocket payments to the practice, and whether surgery was done in hospital or surgical center settings. RESULTS: There were 4 TKA and 3 THA surgeons who were cost-efficiency outliers within our area. Outliers and nonoutlier surgeons had patients who had similar body mass index, American Society of Anesthesiologists Physical Status Score, and age-adjusted Charlson Comorbidity Index scores. Patients of these surgeons had fewer x-ray visits for both TKA and THA (1.06 versus 1.11, P < .001; 0.94 versus 1.15, P < .001) and lower out-of-pocket costs ($86.10 versus $135.46, P < .001; $116.10 versus $177.40, P < .001). If all surgeons performing > 30 CMS cases annually within our practice achieved similar cost-efficiency, the savings to CMS would be $17.2 million for TKA alone ($75,802,705 versus $93,028,477). CONCLUSIONS: The CMS QPP can be used to identify surgeons who perform cost-efficient surgeries. Practice patterns that result in cost savings can be emulated to decrease the cost curve, resulting in reconciliation payments to surgeons and institutions and cost savings to CMS.
RESUMO
BACKGROUND: Periprosthetic fractures (PPFs) account for approximately 25% of early revisions following total hip arthroplasty (THA). Cemented femoral fixation is associated with a lower-risk of PPF, and collared-cementless stems may reduce the risk as well. The objective of this study was to compare early-PPF rates between cemented, collared-cementless, and non-collared cementless stems in elderly patients. METHODS: A consecutieve-series of 11,522 primary THAs performed between 2016 and 2021 at our institution in patients >65 years of age was identified. Stem types used were categorized as cemented, collared-cementless, or non-collared cementless. Patients undergoing THA who had cemented-stems were older, more commonly women, and more likely to have a posterior-approach. To reduce confounding of patient characteristics, we matched patients in the 3 stem-categories according to age, sex, and body mass index. This generated 3-groups (cemented, collared-cementless, and non-collared cementless) consisting of 936 patients per group. The mean age of these 2,808 patients was 73 years, the mean body mass index was 27, and 67% were women. Logistic regressions were used to evaluate risk-factors for early-PPF. In the entire cohort of primary THA in elderly patients, there were 85 early PPFs (0.7%) over the study period. RESULTS: Non-collared cementless stems were associated with an increased risk of early PPF (OR: 3.11; P = .03) compared to collared-cementless stems. There were no early PPFs in the matched cemented cohort, 6 early PPFs in the matched collared-cementless cohort, and 16 early-PPFs in the matched non-collared cementless cohort (0% versus 0.64% versus 1.71%, P < .001). CONCLUSIONS: In this large-series of patients >65 years of age undergoing primary THA, cemented stem fixation had the lowest incidence of early PPF, but collared-cementless stems had a nearly 3-fold decrease in risk for early PPF compared to non-collared cementless stems.

BACKGROUND: Dislocation after total hip arthroplasty (THA) is a primary reason for THA revision. During THA through the direct anterior approach (DAA), the iliofemoral ligament, which provides the main resistance to external rotation (ER) of the hip, is commonly partially transected. We asked: (1) what is the contribution of the medial iliofemoral ligament to resisting ER after DAA THA? and (2) how much resistance to ER can be restored by repairing the ligament? METHODS: A fellowship-trained surgeon performed DAA THA on 9 cadaveric specimens. The specimens were computed tomography scanned before and after implantation. Prior to testing, the ER range of motion of each specimen to impingement in neutral and 10° of extension was computationally predicted. Each specimen was tested on a 6-degrees-of-freedom robotic manipulator. The pelvis was placed in neutral and 10° of extension. The femur was externally rotated until it reached the specimen's impingement target. Total ER torque was recorded with the medial iliofemoral ligament intact, after transecting the ligament, and after repair. Torque at extremes of motion was calculated for each condition. To isolate the contribution of the native ligament, the torque for the transected state was subtracted from both the native and repaired conditions. RESULTS: The medial iliofemoral ligament contributed an average of 68% (range, 34 to 87) of the total torque at the extreme of motion in neutral and 80% (58 to 97) in 10° of extension. The repaired ligament contributed 17% (1 to 54) of the total torque at the extreme of motion in neutral and 14% (5 to 38) in 10° of extension, restoring on average 18 to 25% of the native resistance against ER. CONCLUSIONS: The medial iliofemoral ligament was an important contributor to the hip torque at the extreme of motion during ER. Repairing the ligament restored a fraction of its ability to generate torque to resist ER.

BACKGROUND: The PROMIS Global-10 is a 10-item questionnaire that assesses general health-related quality of life. There is a paucity of research on the utility of the PROMIS Global-10 in the evaluation of orthopedic conditions. The aim of this study is to compare PROMIS Global-10 and legacy shoulder-specific patient-reported outcome measures (PROMs) in patients undergoing total shoulder arthroplasty (TSA) for shoulder arthritis. METHODS: This retrospective cohort study included patients who underwent TSA for shoulder arthritis and completed preoperative and 1-year postoperative surveys. Primary outcome measures were the physical (PROMIS-P) and mental (PROMIS-M) components of PROMIS Global-10. The legacy PROMs included the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score, the Single Assessment Numeric Evaluation (SANE), and the Shoulder Activity Scale (SAS). Analyses included postoperative changes for each outcome, correlations between measures and a responsiveness assessment. RESULTS: A total of 170 patients met inclusion criteria. Average age and body mass index were 67.7 ± 7.8 years and 28.0 ± 4.9, respectively. All legacy PROMs and PROMIS-P were significantly higher at 1-year follow-up compared with the preoperative level (P < .0001), whereas PROMIS-M did not change (P = .06). Preoperatively, both PROMIS components were either poorly correlated with all legacy PROMs (r < .04, P < .05) or not correlated at all (P > .05). Postoperatively, PROMIS-M was poorly correlated with all legacy PROMs (r < .04, P < .01), whereas PROMIS-P had fair correlation with ASES (r = .5, P < .0001) and poor correlation with SANE and SAS (r < .04, P < .01). A floor effect was observed for SANE, and SANE and ASES had a ceiling effect. The effect sizes for SANE and ASES were high (d = 2.01 and 2.39 respectively), whereas the effect size for SAS was moderate (d = 0.65), and the effect sizes for the PROMIS measures were small (d < .5). ASES was the most responsive measure and PROMIS-M was the least responsive. CONCLUSION: PROMIS Global-10 had limited correlation with legacy PROMs and was less responsive at 1-year follow-up in patients following TSA. The Global-10 appears to have limited utility in the evaluation of patients with shoulder arthritis both preoperatively and after TSA.

BACKGROUND: We sought to examine bilateral total knee arthroplasty (BTKA) vs unilateral TKA (UTKA) utilization and in-hospital complications comparing African Americans (AAs) and Whites. METHODS: In this retrospective analysis of patients ≥50 years who underwent elective primary TKA, the (2007-2016) database of the Healthcare Cost and Utilization Project (National Inpatient Sample) was used. We computed differences in temporal trends in utilization and major in-hospital complication rates of BTKA vs UTKA comparing AAs and Whites. We performed multivariable logistic regression models to assess racial differences in trends adjusting for individual-, hospital- and community-level variables. Discharge weights were used to enable nationwide estimates. We used multiple imputation procedures to impute values for 12% missing race information. RESULTS: An estimated 276,194 BTKA and 5,528,429 UTKA were performed in the US. The proportion of BTKA among all TKAs declined, and AAs were significantly less likely to undergo BTKA compared to Whites throughout the study period (trend P = .01). In-hospital complication rates for UTKA were higher in AAs compared to Whites throughout the study period (trend P < .0001). However, for BTKA, the in-hospital complication rates varied between Whites and AAs throughout the study period (trend P = .09). CONCLUSION: In this nationwide sample of patients who underwent total knee arthroplasty from 2007 to 2016, the utilization of BTKA was higher in Whites compared to AAs. On the other hand, while AAs have consistently higher in-hospital complication rates in UTKA over the time period, this pattern was not consistent for BTKA.

PURPOSE: The purpose of this study was to compare the number of opioids prescribed with the amount of pain medication required after knee arthroscopy and related surgery in adolescent and young adult patients to determine the effectiveness of current pain-control practices at a single institution. The secondary purpose was to determine what demographic or surgical factors are associated with increased opioid intake. METHODS: Adolescent and young adult patients who underwent knee arthroscopy and related surgery, including ligament reconstruction or tibial tubercle osteotomy, between May and August 2016 were provided pain-control logbooks in which they were asked to maintain a record of daily pain medication intake. The outcome of the study was defined as the total number of opioids consumed per patient. RESULTS: One hundred patients returned completed logbooks, 56% of whom were female patients. The average age was 17.54 years (standard deviation [SD], 3.51 years). Most patients underwent an open procedure concurrent with knee arthroscopy (60%), underwent nerve block placement (51%), and underwent injection of local anesthesia (91%). Use of both intravenous acetaminophen and ketorolac during the perioperative period was also common (41%). Patients were prescribed an average of 50.98 oxycodone pills (SD, 12.50 pills) and reported consuming an average of 16.52 pills (SD, 13.94 pills), approximately 32.4% of those prescribed. Eleven percent never consumed opioids, and only 1 patient requested a refill during the 21-day postoperative period. Multivariate analysis showed that increased weight, longer surgery time, and increased diazepam use were most closely associated with increased opioid consumption. CONCLUSIONS: After knee arthroscopy and related surgery, including ligament reconstruction or tibial tubercle osteotomy, adolescent and young adult patients are commonly overprescribed opioids, consuming on average only approximately one-third of those prescribed. LEVEL OF EVIDENCE: Level IV, case series.

BACKGROUND: In response to the growing burden of joint disease, developing countries are starting to create their own total joint arthroplasty (TJA) programs. To date, there has been limited research on predictors of TJA outcomes in a developing country. This investigation uses patient-reported outcome measures collected by a medical mission to assess predictors of TJA outcomes in the Dominican Republic. METHODS: Baseline and postoperative information from 156 of the mission's recipients of hip and knee TJA was used. Demographics were abstracted from clinical notes, and self-reported pain and functional status were assessed using Western Ontario and McMaster University Osteoarthritis Index and Short-Form 36 measures. Bivariate analysis identified variables to include in multivariable regression models of factors associated with function and pain outcomes and improvement in these domains 1 or 2 years postoperatively. RESULTS: The cohort had a mean age of 61.3 years, 82% were female, 79% had total knee arthroplasty, and 42% of the procedures were bilateral. In multivariate analyses, at P < .05, male sex, better preoperative function, and use of bilateral procedure were associated with better functional outcome. Male sex and worse preoperative pain were associated with better pain outcome. Worse preoperative pain and function, as well as bilateral surgery were associated with greater improvement in function. Additionally, a greater number of bothersome joints was associated with greater pain reduction. CONCLUSION: Our findings of better follow-up pain scores among patients with worse pain preoperatively and better functional improvement among those undergoing bilateral replacements contrast with study results from developed countries. The explanations for these observations merit further study.

Purpose: Effective patient-doctor communication is linked to improved patient functional and physiological health status, better adherence to physician recommendations, and increased patient satisfaction. However, studies show that patients have difficulty understanding and recalling information discussed during a medical encounter. The purpose of this study was to assess patient engagement, patient-doctor communication, and patient-doctor interactions with the utilization of a patient encounter card to help aid in communication. Methods: New patients presenting to a single hand surgeon during an 8-month period between 2019 and 2020 were recruited for this study. Patients were recruited in pre and postintervention phases, defined by the rollout of a patient encounter card. Patients studied in the preintervention group were defined as the control population and experienced a typical office visit. The postintervention group experienced a typical office visit with the addition of a patient encounter card distributed to patients prior to meeting with the physician and screened by the physician during the visit to guide the encounter. Patient satisfaction and engagement surveys were collected during patient checkout process. Results: Two hundred eighty-seven patients (70% participation rate) were enrolled in the preintervention (145) and postintervention (142) phases. The utilization of a patient encounter card for setting a visit agenda resulted in a significant increase in self-reported patient engagement, improving from 74% to 88%. In both phases, 98% of patients felt that the physician listened well or very well and reported high levels of confidence in the provider being able to address their primary health concerns (72% and 79%, respectively). Overall, patient satisfaction was maintained pre and postintervention (96% and 98%, respectively). Conclusions: Use of the encounter card improved patients' feelings of engagement during their visits. Further research is required to determine the impact of these tools on providers' engagement and patient outcomes to improve quality of care in hand surgery. Type of study/level of evidence: Therapeutic II.
RESUMO
OBJECTIVE: To describe the variability in the return-to-play (RTP) decisions of experienced team clinicians and to assess their clinical opinion as to the relevance of 19 factors described in a RTP decision-making model. DESIGN: Survey questionnaire. SETTING: Advanced Team Physician Course. PARTICIPANTS: Sixty-seven of 101 sports medicine clinicians completed the questionnaire. MAIN OUTCOME MEASURES: Results were analyzed using descriptive statistics. For categorical variables, we report percentage and frequency. For continuous variables, we report mean (SD) if data were approximately normally distributed and frequencies for clinically relevant categories for skewed data. RESULTS: The average number of years of clinical sports medicine experience was 13.6 (9.8). Of the 62 clinicians who responded fully, 35% (n = 22) would "clear" (vs "not clear") an athlete to participate in sport even if the risk of an acute reinjury or long-term sequelae is increased. When respondents were given 6 different RTP options rather than binary choices, there were increased discrepancies across some injury risk scenarios. For example, 8.1% to 16.1% of respondents who chose to clear an athlete when presented with binary choices, later chose to "not clear" an athlete when given 6 graded RTP options. The respondents often considered factors of potential importance to athletes as nonimportant to the RTP decision process if risk of reinjury was unaffected (range, n = 4 [10%] to n = 19 [45%]). CONCLUSIONS: There is a high degree of variability in how different clinicians weight the different factors related to RTP decision making. More precise definitions decrease but do not eliminate this variability.

Background: Congenital heart defects, such as atrial septal defects (ASDs) and patent foramen ovale (PFO), may increase the risk of embolic events in total hip or knee arthroplasty (THA/TKA). The objective of this study was to determine the 90-day incidence of intraoperative and postoperative embolic events and all other complications in patients with a known ASD/PFO who underwent primary hip and knee arthroplasty. Methods: This is a retrospective review of 160 patients with ASD/PFO undergoing 196 primary arthroplasties (94 THAs, 102 TKAs) at a single institution. The mean age was 64 years (standard deviation [SD] 11.1), 40.6% were male, and average body mass index was 31 kg/m2 (SD 7.2). The mean follow-up period was 19 months (SD 16). Forty-three percent of patients were on anticoagulation preoperatively. All patients received postoperative thromboprophylaxis (48% aspirin, 31% direct oral anticoagulants, 18% warfarin, 3% enoxaparin). Results: There were no embolic events identified. Fourteen patients (7%) developed complications within 90 days. Three had bleeding complications, and 8 had other nonoperative complications, which were all managed conservatively and had uneventful recoveries. Additionally, 3 patients had complications requiring reoperations: 2 for periprosthetic fractures (1 THA, 1 TKA) and 1 for a periprosthetic infection (TKA). Conclusions: In this cohort of patients with a known ASD/PFO undergoing THAs and TKAs, there were no cases of embolic events. However, it would be advisable to have a thorough cardiology evaluation to assess potential risks and benefits of defect repair prior to total joint arthroplasty and to reduce the risk of paradoxical embolic events and the necessity of potent anticoagulation. Level of evidence: Prognostic Level IV.
RESUMO
Whether to undergo bilateral total knee arthroplasty (BTKA) depends on patient and surgeon preferences. We used the National Inpatient Sample to compare temporal trends in BTKA utilization and in-hospital complication rates among TKA patients ≥50 with Medicare/Medicaid versus private insurance from 2007 to 2016. We used multivariable logistic regression to assess the association between insurance type and trends in utilization and complication rates adjusting for individual-, hospital-, and community-level covariates, using unilateral TKA (UTKA) for reference. Discharge weights were used for nationwide estimates. About 132,400 (49.5%) Medicare/Medicaid patients and 135,046 (50.5%) privately insured patients underwent BTKA. Among UTKA patients, 62.7% had Medicare/Medicaid, and 37.3% had private insurance. Over the study period, BTKA utilization rate decreased from 7.18% to 5.63% among privately insured patients and from 4.59% to 3.13% among Medicaid/Medicare patients (P trend difference <0.0001). In multivariable analysis, Medicare/Medicaid patients were less likely to receive BTKA than privately insured patients. Although Medicare/Medicaid patients were more likely to develop in-hospital complications after UTKA (adjusted odds ratio, 1.06; 95% confidence interval, 1.002 to 1.12; P = 0.04), this relationship was not statistically significant for BTKAs. In this nationwide sample of TKA patients, BTKA utilization rate was higher in privately insured patients compared with Medicare/Medicaid patients. Furthermore, privately insured patients had lower in-hospital complication rates than Medicare/Medicaid patients.

OBJECTIVE: Return-to-play (RTP) decisions are a central component of the Team Physician's clinical work, yet there is little more than anecdotal reference to these in the literature. We recently published a 3-step model for return-to-play medical decision making and, in the current paper, undertook a systematic review of the literature to determine the level of evidence in support of this model. DATA SOURCES: PubMed, Web of Science, and CINAHL electronic databases. Any article specifically related to concussion, head injuries, neck injuries, illness, medical conditions (including cardiovascular and renal), and preparticipation in sport or that reported RTP as a clinical outcome was excluded. Any article that contained a discussion on one of the components of the 3-step decision-based RTP model was included. RESULTS: We reviewed 148 articles that met the criteria for inclusion and found 98 review articles, 39 original articles, 6 case reports, and 5 editorials. Of these, 141 articles mentioned Step 1 of the medical decision-making process for RTP (Medical Factors), 26 mentioned Step 2 (Sport Risk Modifiers), and 20 mentioned Step 3 (Decision Modifiers). Of the 148 articles in total, only 13 focused on RTP as the main subject and the remaining 135 mentioned RTP anecdotally. Of these 13 articles, 5 were reviews, 4 were editorials, and 4 were original research. CONCLUSIONS: Although 148 articles we retrieved mention RTP in relation to a specific injury, medical condition, or specific topic, only 13 articles focused specifically on the RTP decision-making process, and 6 of 13 were restricted to Step 1 of the 3-step model (Medical Factors). Return-to-play is a fertile field for research and thought leadership beginning with a focus on the Team Physician's appropriate role in RTP decision making, particularly considering the factors identified in Step 3 (Decision Modification).

BACKGROUND: Osteochondral allograft (OCA) transplantation is an increasingly common treatment for patients with symptomatic focal chondral lesions of the knee. There has been increasing interest in determining predictive factors to maximize patient benefit after this operation. The aim of the present study is to evaluate the predictive association of the physical component (PCS) and mental component (MCS) scores of the Short Form 36 (SF-36) questionnaire for achievement of the minimal clinically important difference (MCID) after OCA transplantation. METHODS: This retrospective study of a longitudinally maintained institutional registry included 91 patients who had undergone OCA transplantation for symptomatic focal osteochondral lesions of the femoral condyle. Included patients were those with complete preoperative questionnaires for the SF-36 and IKDC and completed postoperative IKDC at 2-year follow-up. Multivariate analysis was performed evaluating predictive association of the preoperative MCS and PCS with achievement of the MCID for the IKDC questionnaire. RESULTS: Logistic multivariate modeling demonstrated a statistically significant association between lower preoperative PCS and achievement of the MCID (P = 0.022). A defect diameter >2 cm was also associated with achievement of MCID (P = 0.049). Preoperative MCS did not demonstrate a significant association (P = 0.09) with achievement of the MCID. CONCLUSIONS: For this cohort of 91 patients, the preoperative SF-36 PCS and lesion size were predictive of achievement of the MCID at 2-year follow-up after femoral OCA transplantation. These findings support an important role of baseline physical health scores for predicting which patients will obtain a meaningful clinical benefit from this surgery.

The Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10 assesses generic-related quality of life, but has not been well studied in the orthopaedic literature. The purpose was to compare PROMIS Global-10 and legacy hip-specific patient-reported outcome measures (PROMs) in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS). This study included patients who underwent primary hip arthroscopy with complete preoperative and 6-month post-operative follow-up. PROMIS Global-10 Physical (PROMIS-P) and Mental (PROMIS-M) components, as well as the modified Harris hip score (mHHS) and International Hip Outcome Tool-33 (iHOT-33) were assessed. PROM analysis included: post-operative changes, correlations, floor and ceiling effects and responsiveness. Final analysis included 112 patients. Average age and body mass index were 36.1±11.7 years and 24.8±3.9 kg/m2, respectively. All 6-month PROMs, except PROMIS-M, were significantly improved compared to preoperative level (P<0.02). Preoperatively, PROMIS-P was poorly correlated with mHHS and iHOT-33 (r s <0.4) whereas PROMIS-M was only poorly correlated with iHOT-33 (r s <0.4, 95% CI of 0.02-0.37). Post-operatively, the iHOT-33 was poorly correlated with both PROMIS measures (r s <0.4). The mHHS was fairly correlated with both PROMIS measures (r s <0.6) post-operatively. The effect sizes for mHHS and iHOT-33 were high (d=1.2 and 1.40, respectively), whereas the effect sizes for PROMIS Global-10 were small (d<0.3). PROMIS Global-10 demonstrated lower effect sizes and poor to fair correlation with legacy hip-specific PROMs, and appears to have a limited role in the assessment of patients undergoing hip arthroscopy for FAIS. Therefore, the PROMIS Global-10 may have a limited role in assessing patients with FAIS.
RESUMO
BACKGROUND: Bilateral leg power is being increasingly investigated as a proxy for the recovery of muscle performance after injury. Functional tests like the single leg hop for distance (SLHD) and single leg vertical jump (SLVJ) are often used to determine symmetry and return to play (RTP) readiness. As an injury predictor, leg power is accurately measured with the Keiser Air420 seated leg press. PURPOSE: To measure and analyze lower leg asymmetry in healthy collegiate athletes across each test battery. METHODS: Eighty-eight healthy student-athletes (44 males, 44 females) across 14 varsity teams at Wake Forest University performed the SLHD, SLVJ, and the Keiser. Horizontal and vertical displacement were measured via the SLHD and SLVJ, respectively. Peak power was recorded via the Keiser Air420 leg press. Pearson correlations and repeated measures ANOVA were used to calculate associations and compare bilateral asymmetry indices (BAI) and raw scores. RESULTS: There was a significant effect on each test's raw BAI (P < 0.01). The mean absolute BAI were 5.42 ± 4.9%, 6.64 ± 4.9% and 5.36 ± 4.7% for the SLHD, SLVJ and Keiser, respectively. The SLVJ and Keiser (dominant leg r = 0.832, nondominant leg r = 0.826) were more highly correlated than the SLHD and Keiser (dominant leg r = 0.645, nondominant leg r = 0.687), all of which were statistically significant (P < 0.01). CONCLUSION: At the 90th percentile, healthy collegiate athletes attained <15% BAI. We recommend the implementation of a battery of tests to determine normative lower limb asymmetry. A battery of functional tests may present different asymmetry indices as opposed the 10% reference asymmetry.

RESUMO
BACKGROUND: Medical missions to low and middle-income countries are increasingly frequent, with an estimated 6,000 trips sponsored by U.S. organizations accounting for approximately 200,000 surgical cases and $250 million in costs annually. However, these missions have received little critical evaluation. This paper describes the research program Operation Walk (Op-Walk) Boston, and proposes an evaluation model for similar surgical missions. METHODS: We propose an evaluation model, borrowing from the work of Donabedian and enriched by evidence from our research program. The model calls for evaluation of the salient contextual factors (culture and beliefs), system management (structure, process, and outcomes), and sustainability of the program's interventions. We used these domains to present findings from the quantitative and qualitative research work of Op-Walk Boston. RESULTS: Op-Walk's qualitative research findings demonstrated that cultural factors are important determinants of patients' perceptions of arthritis etiology, physical activity patterns, and treatment preferences. Quantitative assessments documented that Dominican patients had worse lower-extremity functional status (mean Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC] function score of 33.6) and pain preoperatively than patients undergoing total hip or knee replacement in the U.S. (WOMAC function score of 43.3 to 54), yet they achieved excellent outcomes (50-point improvement), comparable to those of their U.S. counterparts. Assessments of the quality and sustainability of the Op-Walk program showed that the quality of care provided by Op-Walk Boston meets Blue Cross Blue Shield Centers of Excellence (Blue Distinction) criteria, and that sustainable changes were transferred to the host hospital. CONCLUSIONS: Our proposed model offers a method for formal assessment of medical missions that addresses the call for evidence of their merit. We suggest that surgical missions adopt quantitative and qualitative strategies to document their impact, identify areas of improvement, and justify program continuation, growth, and support.

BACKGROUND: There is growing concern about the use of opioids prior to total knee arthroplasty (TKA), and research has suggested that preoperative opioid use may lead to worse pain outcomes following surgery. We evaluated the pain relief achieved by TKA in patients who had and those who had not used opioids use before the procedure. METHODS: We augmented data from a prospective cohort study of TKA outcomes with opioid-use data abstracted from medical records. We collected patient-reported outcomes and demographic data before and 6 months after TKA. We used the Pain Catastrophizing Scale and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) to quantify the pain experiences of patients treated with TKA who had had a baseline score of ≥20 on the WOMAC pain scale (a 0 to 100-point scale, with 100 being the worst score), who provided follow-up data, and who had not had another surgical procedure within the 2 years prior to TKA. We built a propensity score for preoperative opioid use based on the Pain Catastrophizing Scale score, comorbidities, and baseline pain. We used a general linear model, adjusting for the propensity score and baseline pain, to compare the change in the WOMAC pain score 6 months after TKA between persons who had and those who had not used opioids before TKA. RESULTS: The cohort included 156 patients with a mean age of 65.7 years (standard deviation [SD] = 8.2 years) and a mean body mass index (BMI) of 31.1 kg/m (SD = 6.1 kg/m); 62.2% were female. Preoperatively, 36 patients (23%) had had at least 1 opioid prescription. The mean baseline WOMAC pain score was 43.0 points (SD = 12.8) for the group that had not used opioids before TKA and 46.9 points (SD = 15.7) for those who had used opioids (p = 0.12). The mean preoperative Pain Catastrophizing Scale score was greater among opioid users (15.5 compared with 10.7 points among non-users, p = 0.006). Adjusted analyses showed that the opioid group had a mean 6-month reduction in the WOMAC pain score of 27.0 points (95% confidence interval [CI] = 22.7 to 31.3) compared with 33.6 points (95% CI = 31.4 to 35.9) in the non-opioid group (p = 0.008). CONCLUSIONS: Patients who used opioids prior to TKA obtained less pain relief from the operation. Clinicians should consider limiting pre-TKA opioid prescriptions to optimize the benefits of TKA. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: Few studies have analyzed the tangible impact of global, philanthropic medical missions. We used qualitative methods to analyze the work of one such mission, Operation Walk Boston, which has made yearly trips to a Dominican Republic hospital since 2008. METHODS: We interviewed twenty-one American and Dominican participants of the Operation Walk Boston team to investigate how the program led to changes at the host Dominican hospital and how the experience caused both mission protocols and U.S. practices to change. Transcripts were analyzed with the use of content analysis. RESULTS: Participants noted that Operation Walk Boston's technical knowledge transfer and managerial examples led to sustainable changes at the Dominican hospital. Additionally, participants observed an evolution in nursing culture, as the program inspired greater independence in decision-making. Participants also identified barriers such as language and organizational hierarchy that may limit bidirectional knowledge transfer. U.S. participants noted that their practices at home changed as a result of better appreciation for different providers' roles and for managing cost in a resource-constrained environment. CONCLUSIONS: Operation Walk Boston catalyzed sustainable changes in the Dominican hospital. Cultural norms and organizational structure are important determinants of program sustainability.
