Spezia MC, Stitgen A, Walz JW, Leary EV, Patel A, Keeney JA. Body Mass Index Improvement Reduces Total Knee Arthroplasty Complications Among Patients Who Have Extreme, But Not Severe, Obesity. J Arthroplasty 2024:S0883-5403(24)00913-6. [PMID: 39233104 DOI: 10.1016/j.arth.2024.08.054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 08/27/2024] [Accepted: 08/29/2024] [Indexed: 09/06/2024] Open
Abstract
BACKGROUND While morbid obesity has been associated with increased complication risk in primary total knee arthroplasty (TKA), limited evidence is available to attribute decreased surgical complication rates with body mass index (BMI) reduction. METHODS We retrospectively assessed 464 unilateral TKAs performed in morbidly obese patients, including 158 extremely obese (BMI > 45) and 306 severely obese patients (BMI 40 to 44.9). A detailed medical record review identified concurrent modifiable risk factors and successful preoperative BMI reduction, reaching either a contemporary risk target (BMI < 40) or an institutionally accepted threshold (BMI < 45). Postoperative blood glucose levels and one-year adverse outcomes (periprosthetic joint infection (PJI), wound dehiscence, knee manipulation, periprosthetic fracture) were compared to 557 contemporary control subjects with expected slightly lower (moderate obesity, BMI 35 to 39.9) or sufficiently lower complication risk (overweight, BMI 25 to 29.9). RESULTS PJI and postoperative hyperglycemia were identified more frequently among morbidly obese patients in comparison with a moderately obese control group. Extremely obese patients (BMI > 45) whose BMI improved below 45 had no measurable difference in infection risk from the control group (OR [odds ratio] 0.84, 95% CI [confidence interval] 0.04 to 16.88), while those with a non-improved BMI had a significantly higher risk (OR 7.70, 95% CI 1.89 to 31.41). No significant differences in the risk for infection were observed between severely obese patients (BMI 40 to 44.9) with preoperative BMI improvement (1.5% rate, OR 1.70, 95% CI 0.17 to 16.57) or non-improvement (1.7% rate, OR 1.87, 95% CI 0.41 to 8.43). CONCLUSIONS Preoperative medical optimization may decrease postoperative TKA complications. The findings of this study support BMI improvement for extremely obese patients (BMI > 45). The assignment of 40 BMI as a threshold for otherwise healthy patients may exclude patients from potential surgical benefits without realizing risk reduction.

Abstract
Obesity and malnutrition affect many patients with osteoarthritis and can predispose patients to worse outcomes after total joint arthroplasty (TJA). However, these modifiable risk factors can be addressed in preoperative optimization programs driven by nurse navigators. Our aim is to provide resources and recommendations for nurse navigators when addressing obesity and malnutrition among TJA patients. In addition to discussions with nurse navigators regarding obesity and malnutrition, a literature review was conducted to assess the current practice standards for management. Nurse navigators often had difficulty implementing long-term interventions, but interventions in the literature included medical and bariatric treatments for obesity and more targeted assessment of nutrition status. These findings are incorporated into our recommendations for nurse navigators. Addressing obesity and malnutrition in preoperative optimization can contribute to improved outcomes, as has been demonstrated in current practice and in the literature.

Abstract
BACKGROUND More than 700,000 people in the United States undergo total knee arthroplasty (TKA) each year. Chronic venous insufficiency (CVI) affects 5% to 30% of adults, sometimes resulting in leg ulceration. These CVI cases in TKAs have been associated with worse outcomes; however, we found no study differentiating CVI severity. METHODS This retrospective study analyzed TKA outcomes at one institution from 2011 to 2021 using patient-specific codes. Analyses included short-term complications (< 90 days postoperative), long-term complications (< 2 years), and CVI status (yes/no; simple/complex/unclassified). Complex CVI consisted of pain, ulceration, inflammation, and/or other complications. Revisions within 2 years and readmissions within 90 days post-TKA were assessed. Composite complications included short-term and long-term complications, revisions, and readmissions. Multivariable logistic regressions predicted complication (any/long/short) as a function of CVI status (yes/no; simple/complex) and potential confounding variables. Of 7,665 patients, 741 (9.7%) had CVI. Among CVI patients, 247 (33.3%) had simple CVI, 233 (31.4%) had complex CVI, and 261 (35.2%) had unclassified CVI. RESULTS There was no difference in CVI versus control in composite complications (P = .722), short-term complications (P = .786), long-term complications (P = .15), revisions (P = .964), or readmissions (P = .438) postadjustment. Composite complication rates were 14.0% without CVI, 16.7% with complex CVI, and 9.3% with simple CVI. Complication rates differed between simple and complex CVI (P = .035). CONCLUSION Overall, CVI did not affect postoperative complications versus control. Patients who have complex CVI are at higher risk for post-TKA complications compared to those who have simple CVI.

J Arthroplasty 2023:S0883-5403(23)00275-9.

Abstract
BACKGROUND The American Association of Hip and Knee Surgeons tasked a 2013 workgroup to provide obesity-related recommendations in total joint arthroplasty. Morbidly obese patients (body mass index (BMI) ≥ 40) seeking hip arthroplasty were determined to be at increased perioperative risk, and surgeons were recommended to encourage these patients to reduce their BMI <40 presurgery. We report the effect of instituting a 2014 BMI <40 threshold on our primary total hip arthroplasties (THAs). METHODS We queried our institutional database to select all primary THAs from January 2010 to May 2020. There were 1,383 THAs that were pre-2014 and 3,273 THAs that were post-2014. The 90-day emergency department (ED) visits, readmissions, and returns to operating room (OR) were identified. Patients were propensity score weight-matched according to comorbidities, age, initial surgical consultation (consult) BMI, and sex. We conducted 3 comparisons: A) pre-2014 patients who had a consult and surgical BMI ≥40 against post-2014 patients who had a consult BMI ≥40 and surgical BMI <40; B) pre-2014 patients against post-2014 patients who had a consult and surgical BMI <40; and C) post-2014 patients who had a consult BMI ≥40 and surgical BMI <40 against post-2014 patients who had a consult BMI ≥40 and surgical BMI ≥40. RESULTS Post-2014 patients who had a consult BMI ≥ 40 and surgical BMI <40 had less ED visits (7.6 versus 14.1%, P = .0007), but similar readmissions (11.9 versus 6.3%, P = .22) and returns to OR (5.4 versus 1.6%, P = .09) compared to pre-2014 patients who had a consult BMI and surgical BMI ≥ 40. Post-2014 BMI <40 had less readmissions (5.9 versus 9.3%, P < .0001), and similar all-cause returns to OR and ED visits than patients pre-2014. Post-2014 patients who had a consult and surgical BMI ≥ 40 had lower readmissions (12.5 versus 12.8%, P = .05), and similar ED visits and returns to OR than consult BMI ≥ 40 and surgical BMI <40. CONCLUSION Patient optimization prior to total joint arthroplasty is critical. However, the BMI optimization that mitigates risk in primary total knee arthroplasty may not apply to primary THA. We observed a paradoxical increased readmission rate for patients who reduced their BMI before THA. LEVEL OF EVIDENCE III.

Temporal trends in the rate of complications and prolonged length of stay relative to body mass index in patients undergoing total knee arthroplasty from 2012 to 2020. Knee 2023; 41:266-273. [PMID: 36773372 DOI: 10.1016/j.knee.2023.01.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 12/13/2022] [Accepted: 01/26/2023] [Indexed: 02/13/2023]
Abstract
BACKGROUND Elevated body mass index (BMI) is a risk factor for complications following total knee arthroplasty (TKA). Thus, we believe it is important to constantly re-evaluate the relationship between BMI and complication risk following TKA. METHOD Patients undergoing primary TKA were identified in a national database from 2012-2020. Rates of major complications, minor complications, and length of stay (LOS) greater than 2 days were calculated. The prevalence of postoperative outcomes were calculated per unit of BMI and then multiplied by a factor of 10^2 or 10^3 in order to create adjusted-BMI (aBMI). To isolate the effect of aBMI on postoperative outcomes, changes over time were analyzed using linear regression analysis controlling for age, sex, American Society of Anesthesiology (ASA) classification and smoking status. RESULTS 365,333 patients were included. Mean BMI 33 ± 6.8. 10,616 (2.9%) of patients had a major postoperative complication, 9,345 (2.6%) minor complications, 3,277 (0.9%) had a deep or superficial surgical site infection (SSI). 133,563 (37%) of patients had LOS > 2 days. From 2012-2020, the ratio of major complications to aBMI decreased significantly by an average of -2.7% per year. The ratio of patients with LOS > 2 days to aBMI decreased significantly by -27% per year. The ratio of SSI to aBMI increased significantly by 10.8% per year. CONCLUSIONS From 2012 to 2020, the ratio of major complications and extended LOS following TKA as a function of BMI has decreased significantly, while the ratio of SSI as a function of BMI has doubled.

Abstract
BACKGROUND Patients commonly develop postoperative pain after total knee arthroplasty (TKA). Acupuncture-related techniques and low-level laser therapy could be beneficial for pain management for older individuals. OBJECTIVE To examine the effect of low-level laser acupuncture (LA) in reducing postoperative pain, pain-related interference in daily life, morphine consumption, and morphine-related side effects in older patients with knee osteoarthritis who underwent TKA. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION A single-blind randomized placebo-controlled trial was conducted. Patients (N = 82) were recruited and randomly assigned via a computer-generated list to the LA group or a placebo group. The LA group received low-level laser therapy at Sanyinjiao (SP6), Taixi (KI3), Kunlun (BL60), Fengshi (GB31), Futu (ST32) and Neiguan (PC6) after TKA, while the placebo acupuncture group received the same treatment procedure without laser energy output. MAIN OUTCOME MEASURES The primary outcome was postoperative pain intensity, and it was measured at baseline and hours 2, 6, 10, 24, 48 and 72 after TKA. The secondary outcomes, including relative pain, postoperative pain-related interference in daily life and morphine consumption, were measured at hours 24, 48 and 72 after TKA. RESULTS Generalized estimating equations revealed significant between-group differences in pain intensity (P = 0.01), and trend differences in pain intensity for the LA group starting at hours 10 to 72 (P < 0.05) and morphine consumption at hours 48 and 72 (P < 0.05). The changes in pain-related interference in daily life were significant (P < 0.05) at 72 h, with the exception of the parameters for worst pain, mood, and sleep. Nausea and vomiting side effects from morphine had significant between-group differences at hours 10 and 24 (P < 0.05). CONCLUSION Low-level LA gradually reduced older patients' postoperative pain intensity and morphine consumption within the first 72 h after their TKA for osteoarthritis. Low-level LA may have benefits as an adjuvant pain management technique for clinical care. TRIAL REGISTRATION ClinicalTrials.gov registration number NCT03995446.

Abstract
AIMS It has been shown that the preoperative modification of risk factors associated with obesity may reduce complications after total knee arthroplasty (TKA). However, the optimal method of doing so remains unclear. The aim of this study was to investigate whether a preoperative Risk Stratification Tool (RST) devised in our institution could reduce unexpected intensive care unit (ICU) transfers and 90-day emergency department (ED) visits, readmissions, and reoperations after TKA in obese patients. METHODS We retrospectively reviewed 1,614 consecutive patients undergoing primary unilateral TKA. Their mean age was 65.1 years (17.9 to 87.7) and the mean BMI was 34.2 kg/m2 (SD 7.7). All patients underwent perioperative optimization and monitoring using the RST, which is a validated calculation tool that provides a recommendation for postoperative ICU care or increased nursing support. Patients were divided into three groups: non-obese (BMI < 30 kg/m2, n = 512); obese (BMI 30 kg/m2 to 39.9 kg/m2, n = 748); and morbidly obese (BMI > 40 kg/m2, n = 354). Logistic regression analysis was used to evaluate the outcomes among the groups adjusted for age, sex, smoking, and diabetes. RESULTS Obese patients had a significantly increased rate of discharge to a rehabilitation facility compared with non-obese patients (38.7% (426/1,102) vs 26.0% (133/512), respectively; p < 0.001). When stratified by BMI, discharge to a rehabilitation facility remained significantly higher compared with non-obese (26.0% (133)) in both obese (34.2% (256), odds ratio (OR) 1.6) and morbidly obese (48.0% (170), OR 3.1) patients (p < 0.001). However, there was no significant difference in unexpected ICU transfer (0.4% (two) non-obese vs 0.9% (seven) obese (OR 2.5) vs 1.7% (six) morbidly obese (OR 5.4); p = 0.054), visits to the ED (8.6% (44) vs 10.3% (77) (OR 1.3) vs 10.5% (37) (OR 1.2); p = 0.379), readmissions (4.5% (23) vs 4.0% (30) (OR 1.0) vs 5.1% (18) (OR 1.4); p = 0.322), or reoperations (2.5% (13) vs 3.3% (25) (OR 1.2) vs 3.1% (11) (OR 0.9); p = 0.939). CONCLUSION With the use of a preoperative RST, morbidly obese patients had similar rates of short-term postoperative adverse outcomes after primary TKA as non-obese patients. This supports the assertion that morbidly obese patients can safely undergo TKA with appropriate perioperative optimization and monitoring.

Abstract
BACKGROUND The shift toward outpatient joint arthroplasty is rapidly growing, but concerns still remain on whether certain patients should be excluded from same-day discharge arthroplasty. The purpose of this study is to evaluate whether morbid obesity is a risk factor for perioperative complications after outpatient joint arthroplasty. METHODS A retrospective review was performed from 2013 to 2017 of all outpatient primary total hip, total knee, partial knee, and revision hip and knee arthroplasties, yielding a cohort of 4863 patients (5988 arthroplasty procedures). Patients were separated and analyzed based on 2 groups: nonmorbidly obese (NMO) (BMI < 40 kg/m2) and morbidly obese (MO) (BMI ≥ 40 kg/m2). The NMO group consisted of 4870 arthroplasties and the MO group consisted of 1118 arthroplasties. Overnight stays, medical complications, and early perioperative complications were assessed between groups. RESULTS Overnight stays occurred in 5.4% of NMO patients and 9.1% of MO patients (P < .001), with medical reasons for the overnight stay occurring in 3.2% of NMO and 6.4% of MO patients (P < .001). Respiratory/sleep apnea was the leading medical reason leading to overnight stay occurring in 4% of MO patients and 0.8% of NMO patients (P < .001). There was no significant difference between groups in direct facility transfers, emergency room visits/admissions, or medical complications within 90 days. Wound revisions, nonrevision surgery, or revisions within 90 days were significant between groups. CONCLUSION MO patients did not have an increased risk of 90-day medical complications, readmission, or revisions after outpatient arthroplasty. However, MO patients did have a significantly higher incidence of overnight stay.

Abstract
Introduction As morbid obesity disproportionately affects minorities and those of lower socioeconomic status, body mass index (BMI) restrictions on total hip arthroplasty (THA) may harm populations already facing disparities in care. Therefore, this study analyzed demographics and outcomes in morbidly obese primary THA patients. Methods The National Inpatient Sample was queried for THAs performed between 2009 and 2016. Of 2,676,086 patients identified, 453,250 had a BMI over 25 kg/m2. Patients were stratified by BMI into overweight (BMI=25.0-29.9 kg/m2), non-morbidly obese (BMI=30.0-40.0 kg/m2), and morbidly obese (BMI>40.1 kg/m2). Patient demographics (age, sex, race, insurance, income, and Charlson Comorbidity Index) and outcomes (length of stay [LOS], mortality, disposition, complications, charges, and costs) were assessed. Categorical and continuous data were analyzed with chi-square analyses and one-way analyses of variance, respectively. Results The number of overweight, non-morbidly obese, and morbidly obese patients increased by 299.0%, 109.3%, and 90.9%, respectively, between 2009 and 2016 (p<0.001). Morbidly obese patients were younger than non-morbidly obese and overweight patients (p<0.001) and had a higher proportion of females (p<0.001) and black patients (p<0.001). Morbidly obese patients most frequently used Medicaid and private insurance (p<0.001). Morbidly obese patients demonstrated a longer LOS, a higher mortality rate, a lower rate of home discharges and the most complications (all, p<0.001). Conclusion These results reflect the worsening obesity epidemic and may be useful in counseling preoperative weight loss to morbidly obese patients to reduce mortality and complications.
