Project description:BackgroundObesity is an established risk factor for complications after total knee arthroplasty (TKA) and is often associated with malnutrition.Questions/purposes1. What is the prevalence of hypoalbuminemia in obese patients undergoing TKA? 2. What is the independent morbidity risk of malnutrition relative to obesity?MethodsTKA cases were identified from the National Surgical Quality Improvement Program from 2005 to 2013. Propensity scores for having preoperative albumin measurements were calculated using demographics, BMI, and modified Charlson Comorbidity Index (CCI). Malnutrition was defined as hypoalbuminemia (<3.5 g/dL). Patients were classified by BMI as follows: non-obese (18.5-29.9), obese I (30-34.9), obese II (35-39.9), or obese III (≥40). Postoperative complications were compared across obesity and nutritional statuses. Multivariable propensity-adjusted logistic regressions were performed to determine associations between malnutrition, obesity, and 30-day outcomes.ResultsThere were 71,599 cases identified, with 34,800 (48.6%) having albumin measurements. Propensity score adjustment adequately accounted for selection bias, with adjusted p > 0.05 for observable characteristics. Malnutrition prevalence increased with BMI (6.1% in obese III vs. 3.7% in non-obese). With propensity-adjusted multivariable analysis, obese III was the only obesity class associated with any complication, wound complication, and reoperation. Hypoalbuminemia was a stronger and more consistent independent risk factor, for any complication, wound, cardiac, or respiratory complications, and death.ConclusionsHypoalbuminemia is a more consistent independent predictor of complications after TKA than obesity. Strategies for medical optimization of these conditions should be investigated.

Project description:The purpose of this study was to investigate the association between insurance type and length of stay (LOS) in primary total joint arthroplasty. A retrospective review of 848 patients was performed. Patients were divided into 3 groups based on their insurance type: Medicare, Medicaid, or commercial coverage. Medicare patients had a significantly higher rate of LOS > 2 days than the Medicaid and commercial groups (P < .0001). The effect of Medicare coverage on LOS remained significant even after controlling for baseline differences among the study groups. There were no differences in the rates of 90-day emergency room visits and readmissions between the 3 groups (P > .05). Arthroplasty surgeons not experienced with outpatient surgery should not be pressured to default to outpatient admission in Medicare patients.

Project description:BackgroundHidradenitis suppurativa (HS) is a skin disorder characterized by inflammatory skin lesions that are most commonly in the inguinal and axillary regions. These skin lesions are common sites of bacterial growth and are thus a potential risk factor for infection following procedures such as total hip arthroplasty (THA) or total knee arthroplasty (TKA).Material and methodsAdult patients undergoing THA or TKA for degenerative etiologies were identified from PearlDiver datasets. For THA and TKA, HS patients were matched 1:4 with non-HS patients based on age, sex, and Elixhauser Comorbidity Index. The incidence of 90-day any, severe, minor, and specific adverse events was compiled and compared with multivariate analyses. Five-year revision rates were plotted on Kaplan-Meier survival curves and compared with log-rank tests.ResultsFor THA, 331,627 patients were identified, of which HS was noted for 481 patients (0.15%). For TKA, 274,161 patients were identified, of which HS was noted for 290 patients (0.11%). Following THA, HS patients had increased odds of wound dehiscence (odds ratio = 2.55, P = .002). Following TKA, HS patients had increased odds of surgical site infection (odds ratio = 1.95, P = .006). All other 90-day adverse events were not significantly different. There was no significant difference in 5-year implant survival in either procedure.ConclusionsHS is a rare but identified comorbidity for those undergoing THA or TKA. Although most 90-day adverse events and 5-year implant survival were similar to those without this condition, specific wound-related issues were elevated by roughly twofold. These findings could help inform patients and surgeons.

Project description:BackgroundIn patients with total elbow arthroplasty (TEA), the soft-tissue around the elbow can be vulnerable to soft-tissue complications. This study aims to assess the outcomes after soft-tissue reconstruction following TEA.MethodsWe retrospectively included nine adult patients who underwent soft-tissue reconstruction following TEA. Demographic data and disease characteristics were collected through medical chart reviews. Additionally, we contacted all four patients that were alive at the time of the study by phone to assess any current elbow complications. Local tissue rearrangement was used for soft-tissue reconstruction in six patients, and a pedicle flap was used in three patients. The median follow-up period was 1.3 years (range, 6 months-14.7 years).ResultsSeven patients (78%) underwent reoperation. Four patients (44%) had a reoperation for soft-tissue complications, including dehiscence or nonhealing of infected wounds. Five patients (56%) had a reoperation for implant-related complications, including three infections and two peri-prosthetic fractures. At the final follow-ups, six patients (67%) achieved successful wound healing and two patients had continued wound healing issues, while two patients had an antibiotic spacer in situ and one patient underwent an above-the-elbow amputation.ConclusionsThis study reports a complication rate of 78% for soft-tissue reconstructions after TEA. Successful soft-tissue healing was achieved in 67% of patients, but at the cost of multiple surgeries. Early definitive soft-tissue reconstruction could prove to be preferable to minor interventions such as irrigation, debridement, and local tissue advancement, or smaller soft-tissue reconstructions using local tissue rearrangement or a pedicled flap at a later stage.

Project description:Periprosthetic joint infection (PJI) can be protracted, incapacitating, needing multiple interventions and could even lead to mortality. Early post-operative PJI has been ascribed to peri-operative introduction of highly virulent bacteria, while delayed post-operative to low-virulence bacteria. Non-tuberculous mycobacteria (NTM) do not figure in the usual list of etiological agents. We report a case of difficult diagnosis of bilateral PJI caused by Mycobacterium abscessus, following bilateral total knee arthroplasty in an elderly male, but treated successfully despite prolonged infection. M. abscessus complex comprises a group of rapidly growing, multidrug-resistant NTM, capable of forming biofilms on prostheses, responsible for wide spectrum of hospital acquired infections. M. abscessus as a cause of PJI is not reported widely. There are a few cases described in literature worldwide. There are no policy guidelines available for treating such cases. High clinical suspicion, with a concerted effort to grow and identify the causal pathogen is important. Standard anti-tubercular therapy is not recommended for treatment due to inherent resistance. Complete excision of infected tissues and removal of prosthesis along with prolonged combination antimicrobial regimen is the treatment of choice.

Project description:BACKGROUND:Minority patients are at higher risk for complications and readmissions after total hip and knee arthroplasty. They are also more likely to undergo joint replacement in lower volume centers, which is associated with poorer outcomes. It is unknown whether these disparities simply reflect disproportionate use of lower volume centers. This study evaluates the impact of hospital volume on racial differences in outcomes following joint replacement. METHODS:Patients who underwent total hip or knee arthroplasty between 2006 and 2013 in New York and Florida were identified through the Healthcare Cost and Utilization Project State Inpatient Databases. Complications, readmissions, and emergency department (ED) visits within 90 days were compared by hospital volume. Relative risks were calculated with generalized estimating equations for risk factors associated with adverse outcomes. RESULTS:Race/ethnicity was not associated with readmission following hip replacement. Black race was associated with readmission following knee replacement (relative risk [RR] 1.16). Black race was associated with ED visits following hip replacement (RR 1.29) and knee replacement (RR 1.33). Hispanic ethnicity was associated with ED visits following knee replacement (RR 1.15), but not hip replacement. These associations did not change after adjusting for hospital volume. CONCLUSION:Adjusting for hospital volume does not alter the risk of readmissions and ED use associated with minority race/ethnicity, suggesting that hospital volume alone may be insufficient to explain racial differences in outcome.

Project description:A dysfunctional distal radioulnar joint (DRUJ) can significantly compromise an individual's forearm rotation, grip, and weight bearing at the hand and wrist. This retrospective study reports surgeon- and therapist-collected objective wrist function and subjective pain scores of 10 patients who received the Scheker total DRUJ prosthesis. A review of these patients' medical records was performed to collect preoperative measurements of wrist range of motion (ROM), grip strength, and pain scores (0-10 scale). The degree of pronation, supination, flexion, extension, radial deviation, and ulnar deviation were the outcome measures used to evaluate wrist ROM. Postoperative measurements were collected at a follow up of 5 ± 1.1 years in our clinic (minimum follow-up of 2yrs). Mean final wrist flexion and extension were 32.1 ± 22.8° and 44.8 ± 13.9°, respectively. Mean final supination and pronation were 72.5 ± 14.4° and 69.5 ± 14.6°, respectively. Average grip strength was 54.9 ± 23.7 lbs. The mean pain score was 3.6 ± 3.1. Although there were no statistically significant changes in any of these outcome measures, the Scheker prosthesis improved wrist ROM (with the exception of wrist flexion) and decreased pain. Grip strength decreased by less than 1 lb but was still higher than the postoperative grip strength measurements in the literature for this prosthesis. Because of the self-stabilizing nature of this prosthesis and the satisfactory functional outcomes from this study and other studies, the Scheker prosthesis is still a viable option for DRUJ pathology that is refractory to nonimplant arthroplasties. This is a therapeutic level IV study.

Project description:Background:The use of perioperative surgical wound dressings is an important factor in the mitigation of infection following total joint arthroplasty (TJA). Few studies have been published comparing wound dressings and infection rates after TJA. Methods:MEDLINE, PubMed, and EMBASE were searched for studies published between 2006 and 2016 reporting infection rates in patients using various wound dressings after undergoing TJA. All studies comparing Hydrofibre dressings to Standard dressings or Absorbent dressings were included in this meta-analysis. Studies looking at TJA secondary to trauma were excluded. Two individuals independently extracted data, and study results were divided based on type of treatment. The primary outcome was to compare the infection rate of Hydrofibre dressings to that of both Standard Dressings and Absorbent dressings. Results:Of a total of 3721 participants, 1483 were treated with Standard dressings (non-impregnated gauze), 1911 with Hydrofibre dressings, and 327 with Absorbent dressings. The risk ratio for infection comparing Standard with Hydrofibre was 4.16 (95% confidence interval, 1.71-10.16) as compared to 2.60 (95% confidence interval, 0.66-10.27) when comparing Absorbent with Hydrofibre dressings. Conclusions:Our analysis suggests that Hydrofibre dressings may be significantly better than Standard and Absorbent dressings with respect to reducing infection. However, given the observed heterogeneity and small number of studies included, more comparative studies are needed to definitively recommend superiority among dressings following TJA. Level of Evidence:Level 1.

Project description:BackgroundAlthough Medicaid expansion has improved access to primary care services, its impact on surgical specialty utilization remains unclear. The aim of this study is to determine whether Medicaid expansion is associated with increased utilization rates of total hip arthroplasty (THA) and total knee arthroplasty (TKA) in Illinois (which expanded Medicaid) relative to Missouri (which did not expand Medicaid).MethodsUsing administrative data sources, we analyzed 374,877 total hospitalizations (236,333 in Illinois and 138,544 in Missouri) for THA/TKA from 2011 to 2016 (Illinois' Medicaid expansion date: January 1, 2014).ResultsThe percentage of THA/TKA funded by Medicaid in Illinois was 2.4% in 2013 and 3.9% in 2016 (Missouri 2013: 2.7%; 2016: 2.6%). A difference-in-difference analysis (adjusted for patient age and gender, county-level Area Deprivation Index, and number of orthopedic surgeons) demonstrated a statistically significant increase in Medicaid-funded THA/TKA in Illinois in 2016 compared to 2013 (P = .012).ConclusionOur study demonstrates that Medicaid expansion in Illinois was associated with increased utilization of THA and TKA. Further study is needed to understand the impact of Medicaid expansion in other states and for other procedures.

Project description:BackgroundSurgeons who lack experience with total ankle arthroplasty (TAA) may remain hesitant to introduce this procedure owing to previously published results of high complication rates during initial cases. The purpose of the present study was to report the development of a TAA program through intermediate outcomes and complications for an initial consecutive series of TAA patients of a single community-based foot and ankle fellowship-trained orthopedic surgeon with little TAA experience using a co-surgeon with similar training and TAA exposure.MethodsThe initial 20 patients following third-generation TAA with a single surgeon were reviewed. Clinical outcomes were measured and radiographs were evaluated to determine postoperative implant and ankle position. Complications were also measured including intraoperative, early (<3 months), and intermediate postoperative complications.ResultsWith a minimum follow-up of 2 years and average follow-up of 51 months (range 24-70 months), the mean American Orthopaedic Ankle & Foot Society Ankle-Hindfoot score was 87.7 (59-100) and VAS was 1.0 (0-5.5). All patients were improved following TAA. Radiographic evaluation demonstrated no evidence of component malalignment or ankle joint incongruity. There were no intraoperative complications nor any wound complications. Three patients returned to the operating room for placement of medial malleolar screw placement, and 1 had asymptomatic tibial component subsidence.ConclusionsOrthopedic surgeons with a proper background and updated training may be able to perform TAA with good outcomes. A TAA program was developed to define minimum training criteria to perform this procedure in our community. Our complication rate is consistent with those reported in the literature for experienced TAA centers, which contrasts previous literature suggesting increased complication rates and worse outcomes when surgeons perform initial TAAs. Utilization of an orthopedic co-surgeon was felt to be instrumental in the success of the program.Level of evidenceLevel IV, retrospective case series.
