What Are Culturally Relevant Activities of Daily Living in the Asian-Indian Population? A Survey of 402 Patients With Knee Pain.

BACKGROUND: Patient-reported outcome measures are essential tools in assessing clinical outcomes. Although several patient-reported outcome measures such as the Oxford Knee Score and Knee Injury and Osteoarthritis Outcome Score have been developed and validated, their applicability in the Asian-Indian population may be limited; key cultural differences including varying functional demands, ethnicity-specific necessities, and social expectations represent a unique collection of needs. Such differences include preferences toward ground-level activities and those favoring the manual completion of tasks. QUESTIONS/PURPOSES: (1) Which activities of daily living (ADLs) do patients in an Asian-Indian population consider the most important? (2) How do the categories of ADLs (personal care, household, work, travel, and recreation) vary among patients of different gender (men and women) and age (< 60 and > 60 years) groups? METHODS: A cross-sectional study was conducted in October 2019 at a hospital in Mumbai, India. We developed a questionnaire with five domains for physical activity (personal care, household, work, travel, and recreation) formulated from a review and modification of existing categories identified by the WHO and the American Heart Association. Forty key ADLs were identified according to input obtained from detailed interviews of healthcare providers involved in the care of patients with orthopaedic illness, based on established domains. Respondents were instructed to identify the ADLs that were the most relevant to their lifestyle and culture. Responses from 402 patients (mean age 60 ± 12 years; 51% [206 of 402] were women) were analyzed to identify the most commonly selected ADLs. Responses were further evaluated to understand the impact of gender and age on these preferences by comparing men and women, as well as younger (age < 60 years) and older (age > 60 years) patients. RESULTS: The three most frequently reported ADLs in each domain, representing the ADLs that were the most important to the Asian-Indian population, were standing without assistance (82% [331 of 402]), getting up with support (81% [324 of 402]), and toilet use (74% [298 of 402]) in the personal activity category; climbing stairs (80% [322 of 402]), sitting cross-legged (80% [320 of 402]), and praying (79% [319 of 402]) in the household activity category; going to the market (72% [291 of 402]), long-distance walking (62% [250 of 402]), and carrying a shopping bag (60% [242 of 402]) in the work activity category; walking on an uneven surface (66% [266 of 402]), using a taxi (61% [247 of 402]), and traveling by train (59% [239 of 402]) in the travel activity category; and yoga (67% [269 of 402]), playing with children (66% [264 of 402]), and indoor games (63% [252 of 402]) in the recreational activity category. The order of importance of ADL domains was identical in the men versus women groups as well as in the younger age versus older age groups; ADL domains with the highest number of selected ADLs in order of decreasing importance were household care, personal care, work, travel, and recreation when analyzed by individual gender and age groups. Women were more likely than men to report the following ADLs as being important: climbing stairs (84% [172 of 206] of women and 77% [150 of 196] of men), getting up without support (83% [171 of 206] of women and 78% [153 of 196] of men), going to the market (74% [152 of 206] of women and 71% [139 of 196] of men), walking on uneven surfaces (67% [139 of 206] of women and 65% [127 of 196] of men), and playing with children (72% [148 of 206] of women and 59% [116 of 196] of men). CONCLUSION: The findings of this study aim to help providers engage in personalized and socioculturally relevant discussions about knee arthritis. Highlighted areas of importance may facilitate a more comprehensive preoperative discussion of total joint arthroplasty expectations in the context of the needs and demands of Asian-Indian patients. The findings of this study could establish the groundwork for the development of ethnicity-specific patient-reported outcome measures by incorporating the identified ADLs in novel metrics with validation of face and content validity.Level of Evidence Level III, prognostic study.

Concurrent Hardware Removal is Associated With Increased Odds of Infection Following Conversion Total Knee Arthroplasty.

BACKGROUND: The optimal timing of removal of periarticular implants prior to conversion total knee arthroplasty (TKA) remains to be determined. The purpose of this study was to compare infection rates in conversion TKA when hardware removal was performed in either a staged or concurrent manner. METHODS: We performed a retrospective study using a national insurance claims database of patients who underwent removal of hardware on the same day or within 1 year before their TKA. A total of 16,099 patients met the criteria. After matching, both final cohorts consisted of 4,502 patients. The 90-day and 1-year rates of prosthetic joint infection were calculated. RESULTS: The rates of infection were 1.64% and 3.00% in the staged group and 2.62% and 3.95% in the concurrent group at 90 days and 1 year postoperatively, respectively (P = .001, P = .01). Logistic regression analyses demonstrated that patients who had hardware removal greater than 3 months prior to TKA had significantly lower odds of infection at 1-year postop (Odds Ratio 0.61 95% Confidence Interval 0.45-0.84; P = .003). CONCLUSION: Removal of hardware performed concurrently or within 3 months of a TKA is associated with increased odds of prosthetic joint infection at 1 year postoperatively. Surgeons should consider removing periarticular hardware prior to TKA when possible.

The Relationship Between Preoperative Opioid Use and Adverse Events Following Total Knee Arthroplasty.

This study aims to compare perioperative events following total knee arthroplasty (TKA) amongst various degrees of preoperative opioid use. In total, 84,569 patients undergoing TKA were identified from a Humana Claims Dataset, and stratified by their preoperative opioid use based on number of prescriptions filled within 6 months of surgery (naïve 0 [50,561]; sporadic 1 [12,411]; chronic 2 or greater [21,687]). Outcomes of interest included Center for Medicare and Medicaid Services (CMS)-reportable complications, need for postoperative supplemental oxygen, 90-day readmission, and hospital length of stay. Complication rates (9.8% vs 8.9% vs 12.6%; p < 0.01), need for supplemental oxygen (3.0% vs 3.1% vs 5.3%; p = 0.03), mean length of stay (2.1 vs 2.8 vs 3.5; p < 0.01), and 90-day readmission (9.7% vs 10.8% vs 16.4%; p < 0.01) significantly differed amongst groups. On logistic regression, only the chronic opioid use group was associated with significantly increased likelihood of complications, need for supplemental oxygen, and readmission.

A cohort study of multiple families with FBN1 p.R650C variant, ectopia lentis, and low but not absent risk for aortopathy.

Marfan syndrome is a multisystem disease with cardiovascular, ophthalmologic, and skeletal features. Diagnosis is made clinically with emphasis on presence of aortic root dilation and ectopia lentis (EL). Most individuals meeting these criteria have a pathogenic variant in FBN1, usually unique or observed rarely. Individuals with EL alone may also have FBN1 pathogenic variants, and the risk for aortic disease is not well known. We identified a unique cohort of 31 individuals (mean age 29, range 2-78) from nine families ascertained by a proband with EL alone, who had the same FBN1 p.R650C variant. Comparison was made to individuals with Marfan syndrome (n = 103 from 97 families) at our institution. Those with the p.R650C variant had few skeletal features of Marfan syndrome. Age of onset of EL was later compared to others with cysteine variant changes. Aortic root dilation occurred in 4/16 (25%) of the p.R650C group versus 71/83 (86%) in the comparator group (p < 0.001) and dissection or replacement in 1/31 (3%) versus 20/103 (19%; p < 0.04). Aortic root Z scores were much lower in the p.R650C (0.34 ± 1.70) versus the comparator (2.99 ± 2.54; p < 0.0002). Kaplan-Meier failure curves for aortic root dilation demonstrated later age of onset and differed significantly for incidence rate ratio (comparator vs. p.R650C = 5.35, CI 1.84-21.17; p = 0.0001). Individuals with p.R650C predominantly have EL, but do have risk for aortic dilation at ages later than typical for Marfan syndrome in general and for cysteine changes specifically. Surveillance for aortic dilation is required but may occur less frequently.

Surgeon Accuracy in Prediction of Stability of Posterior Wall Acetabular Fractures. A Survey of Orthopaedic Trauma Surgeons.

OBJECTIVES: This study aims to investigate surgeon accuracy in prediction of the stability of posterior wall acetabular fractures by comparing "examination under anesthesia" findings to submitted estimations on the basis of radiograph and computed tomography (CT) imaging across a range of experience in orthopaedic surgeons and trainees. METHODS: Records of patients who underwent examination under anesthesia after presenting with posterior wall acetabular fractures at 2 different institutions were pooled for data collection, totaling 50 cases. Radiographs, CT images, and information regarding the presence of a hip dislocation requiring procedural reduction were provided to participants for review. A survey was generated for submission of impressions of stability for each individual case and disseminated among orthopaedic trainees and surgeons in practice. RESULTS: The submissions of 11 respondents were analyzed. Mean accuracy was calculated to be 0.70 (SD = 0.07). Sensitivity and specificity of respondents were 0.68 (SD = 0.11) and 0.71 (SD = 0.12), respectively. Positive predictive value and negative predictive value for respondents were 0.56 (SD = 0.09) and 0.82 (SD = 0.04), respectively. There was poor correlation of accuracy with years of experience with R 2 calculated to be 0.0004 and poor agreement between observers with Kappa measurement of interobserver reliability of 0.46. CONCLUSIONS: Our study suggests that surgeons are unable to consistently differentiate between stable and unstable patterns on the basis of assessments based on x-ray and CT. Years of experience in training or practice was not found to be associated with improved accuracy of stability prediction.

Impact of Admission Imaging Findings on Neurological Outcomes in Acute Cervical Traumatic Spinal Cord Injury.

Variable and unpredictable spontaneous recovery can occur after acute cervical traumatic spinal cord injury (tSCI). Despite the critical clinical and interventional trial planning implications of this tSCI feature, baseline measures to predict neurologic recovery accurately are not well defined. In this study, we used data derived from 99 consecutive patients (78 male, 21 female) with acute cervical tSCIs to assess the sensitivity and specificity of various clinical and radiological factors in predicting recovery at one year after injury. Categorical magnetic resonance imaging parameters included maximum canal compromise (MCC), maximum spinal cord compression (MSCC), longitudinal length of intramedullary lesion (IML), Brain and Spinal Injury Center (BASIC) score, and a novel derived Combined Axial and Sagittal Score (CASS). Logistic regression analysis of the area under the receiver operating characteristic curve (AUC) was applied to assess the differential predictive value of individual imaging markers. Admission American Spinal Injury Association Impairment Scale (AIS) grade, presence of a spinal fracture, and central cord syndrome were predictive of AIS conversion at one year. Both BASIC and IML were stronger predictors of AIS conversion compared with MCC and MSCC (p = 0.0002 and p = 0.04). The BASIC score demonstrated the highest overall predictive value for AIS conversion at one year (AUC 0.94). We conclude that admission intrinsic cord signal findings are robust predictive surrogate markers of neurologic recovery after cervical tSCI. Direct comparison of imaging parameters in this cohort of patients indicates that the BASIC score is the single best acute predictor of the likelihood of AIS conversion.
