Background
Interest in outpatient/same-day discharge (SDD) total hip arthroplasty (THA) has been increasing over the last several years. There is considerable debate in the literature regarding the complication and readmission rates of these patients. To evaluate and validate the safety and efficacy of our institutional SDD THA care pathway, we compared the outcomes of patients undergoing SDD THA with patients who had a similar comorbidity profile and underwent inpatient THA.Methods
A retrospective review was conducted on 164 patients who underwent SDD THA from January 2015 to September 2016. The Risk of Readmission Tool, a validated risk stratification instrument, was applied to all inpatient THAs performed from June 2014 to December 2016. A cutoff Risk of Readmission Tool score < 3 was used to produce a cohort of 1858 inpatient THA patients, all of whom had a similar risk profile to patients who underwent SDD THA. Medicare patients were excluded from the inpatient THA cohort, which left a final inpatient sample of 1315 patients.Each cohort was evaluated for demographic variables, length of stay, 30-/90-day readmissions, and discharge disposition.Results
The SDD THA cohort had significantly lower body mass index (26.9 vs 28.2 kg/m2; P = .002), had fewer minorities (89.6% vs 66.3% Caucasians; P < .001), was exclusively commercial insurance (100% vs 36.3%), had a shorter length of stay (0.37 vs 2.3 days, P < .001), and was exclusively discharged home (100% vs 92.6%). There was no statistically significant difference in 30-day readmission rates between either cohort (SDD 0.6% vs inpatient 1.6%; P = .325). However, the SDD cohort had a significantly lower rate of 90-day readmissions than the inpatient cohort (0.6% vs 3.6%; P = .014).Conclusion
The use of an institutional SDD THA care pathway can produce results with equivalent or better short-term outcomes than that of traditional inpatient THA. 相似文献2.

Background
Studies regarding postoperative outcomes after primary total hip arthroplasty (THA) in patients who have comorbid factors tend to focus on medical diseases. However, there is a paucity of literature examining the effect of a patient's orthopedic surgical history on outcomes after THA. Significantly, there are currently no studies on the effect of spinal fusion surgery on THA outcomes.Methods
A review of 82 consecutive patients who had prior spinal fusion surgery who underwent elective THA from January 1, 2006 to December 31, 2015, was conducted. A matching cohort of 82 patients was selected from the remaining THA patients to maintain a 1:1 ratio control group. This cohort of 82 patients was matched for age, gender, body mass index ±5, preoperative Oxford score ±10, total Short Form-36 score ±10, and total Western Ontario and McMaster Universities Arthritis Index (WOMAC) score ±50. Data on the same functional outcomes were prospectively collected at 6-month and 2-year follow-up for comparison.Results
Patients without spinal fusion had better outcome scores than patients with prior spinal fusion, specifically in their 6-month WOMAC scores (253.33-225.07; P = .046), their 2-year Short Form-36 total scores (79.71-69.21; P = .041), and their 2-year WOMAC scores (213.5-267.41; P = .054).Conclusion
This study demonstrates that patients with prior spinal fusion had worse outcomes after THA than patients without prior spinal fusion. This has clinical significance in counseling patients with previous spinal fusion undergoing THA. 相似文献3.
Background
The aim of this prospective cohort study is to evaluate the outcome of octogenarian patients undergoing uncemented total hip arthroplasty (THA) with a control group of similarly aged patients undergoing hybrid THA with a minimum 5-year follow-up.Methods
Clinical outcomes including intraoperative and postoperative complications, blood transfusion, revision rate, and mortality were recorded. Radiological analysis of preoperative and postoperative radiographs assessed bone quality, implant fixation, and any subsequent loosening.Results
One hundred forty-three patients (mean age 86.2 years) were enrolled in the study. Seventy-six patients underwent uncemented THA and 67 underwent hybrid THA. The uncemented cohort had a significantly lower intraoperative complication rate (P = .017) and also a lower transfusion rate (P = .002). Mean hospital stay (P = .27) was comparable between the 2 groups. Two patients underwent revision surgery in each cohort.Conclusion
Our study demonstrates that uncemented THA is safe for the octogenarian patient and we recommend that age should not be a barrier to the choice of implant. However, intraoperative assessment of bone quality should guide surgeons to the optimum decision regarding uncemented and hybrid implants.Level of evidence

Background
No studies have compared sports participation between total hip arthroplasty (THA) and periacetabular osteotomy (PAO) in matched Asian cohorts. We investigated sports participation and activity levels in Asian THA cohort, and compared them between THA and PAO cohorts.Methods
Multivariate analyses were applied to determine which factors were associated with postoperative sports participation and University of California-Los Angeles (UCLA) activity score in (1) 524 THA patients and (2) 487 acetabular dysplasia patients (295 THA patients and 192 PAO patients). In addition, postoperative sports participation and UCLA score were compared between 62 THA and 62 PAO patients after adjusting for baseline characteristics with propensity score matching.Results
Sports participation and UCLA score significantly increased after THA (P < .001 in both analyses). Preoperative sports participation was the factor most associated with both postoperative sports participation and UCLA score in both 524 THA patients and 487 acetabular dysplasia patients (P < .001 in all analyses). Multivariate analysis in 487 acetabular dysplasia patients demonstrated that THA, compared with PAO, was negatively associated with postoperative sports participation (P < .001), but not postoperative UCLA score (P = .22). THA patients showed significantly lower rate of postoperative sports participation (32.3% and 51.6%, respectively, P = .046), but not postoperative UCLA score (5.0 ± 1.6 and 5.2 ± 1.9, respectively, P = .47) compared with matched PAO patients.Conclusion
THA significantly increased both sports participation and activity levels. Both multivariate and propensity score-matched analyses showed that postoperative activity levels were comparable between THA and PAO cohorts. 相似文献6.

Background
As the indications for total hip arthroplasty (THA) have expanded, this procedure is being increasingly performed in young patients. Oftentimes, this population has undergone one or more salvage procedures in an attempt to delay or forestall a THA. However, it is unclear whether patients with prior salvage procedure have higher risk of adverse events.Methods
From 2004 to 2014, 215 THAs performed in patients less than 30 years at a single institution were identified. These patients were screened to identify 37 THAs in which one or more salvage procedures were performed prior to the THA (salvage group). The prior salvage procedures were open in 30 (pelvic osteotomy = 5, femoral osteotomy = 15, combined osteotomy = 2, core decompression = 7, bone graft = 1) and arthroscopic in 7. Medical and surgical complications within 90 days and overall survivorship at a minimum follow-up of 2 years were recorded. Nonparametric tests and Kaplan-Meier survival curves were used to compare the groups.Results
Salvage group had a higher rate of wound complications (P = .037), superficial infections (P = .005), and reoperations (P = .015). The 5-year survivorships in the salvage and nonsalvage groups were 97.1% and 96.7%, respectively (P = .787).Conclusion
Patients less than 30 years who undergo THA after a previous salvage procedure have a higher risk of wound complications, superficial infections, and reoperations, but similar survivorship, compared to those who did not have any prior salvage procedures. This information is helpful in counseling young patients while offering various surgical options for the management of various hip pathologies. 相似文献7.

Background
Changes in reimbursement for total hip and knee arthroplasties (THA and TKA) have placed increased financial burden of early readmission on hospitals and surgeons. Our purpose was to characterize factors of 30-day readmission for surgical complications after THA and TKA at a single, high-volume orthopedic specialty hospital.Methods
Patients with a diagnosis of osteoarthritis and who were readmitted within 30 days of their unilateral primary THA or TKA procedure between 2010 and 2014. Readmitted patients were matched to nonreadmitted patients 1:2. Patient and perioperative variables were collected for both cohorts. A conditional logistic regression was performed to assess both the patient and perioperative factors and their predictive value toward 30-day readmission.Results
Twenty-one thousand eight hundred sixty-four arthroplasties (THA = 11,105; TKA = 10,759) were performed between 2010 and 2014 at our institution, in which 60 patients (THA = 37, TKA = 23) were readmitted during this 5-year period. The most common reasons for readmission were fracture (N = 14), infection (N = 14), and dislocation (N = 9). Thirty-day readmission for THA was associated with increased procedure time (P = .05), length of stay (LOS) shorter than 2 days (P = .04), discharge to a skilled nursing facility (P = .05), and anticoagulation use other than aspirin (P = .02). Thirty-day readmission for TKA was associated with increased tourniquet time (P = .02), LOS <3 days (P < .01), and preoperative depression (P = .02). In the combined THA/TKA model, a diagnosis of depression increased 30-day readmission (odds ratio 3.5 [1.4-8.5]; P < .01).Conclusion
Risk factors for 30-day readmission for surgical complications included short LOS, discharge destination, increased procedure/tourniquet time, potent anticoagulation use, and preoperative diagnosis of depression. A focus on risk factor modification and improved risk stratification models are necessary to optimize patient care using readmission rates as a quality benchmark. 相似文献8.

Background
Total hip arthroplasty (THA) provides a successful salvage option for failed acetabular fractures. The complexity of arthroplasty for a failed acetabular fracture will depend on the fracture pattern and the initial management of the fracture. Our objective was to compare the midterm outcome of THA between patients who presented with failed acetabular fractures following initial surgical or nonsurgical treatment.Methods
Forty-seven patients underwent cementless THA ± acetabular reconstruction following failed treatment of acetabular fractures. Twenty-seven were initially treated by surgery (group A) and 20 had nonsurgical treatment (group B). Intraoperative measures, preoperative and follow-up clinical, radiological, and functional outcomes were compared between the 2 groups.Results
The mean surgical time, blood loss, and need for blood transfusion were significantly less in group A (P < .05). Acetabular reconstruction to address cavitary or segmental defects was needed in a significantly higher number of patients in group B (P = .006). Significant improvement in modified Merle d'Aubigne and Oxford scores was seen postsurgery in both groups. Acetabular component survival with aseptic loosening as end point was 98%. Overall survival rate with infection, revision, or loosening as end point was 93% at a mean follow-up of 7 years ± 17 months.Conclusion
THA for a failed acetabular fracture is greatly facilitated by initial surgical treatment. Although functional results and survivorship were similar in both groups, failed nonsurgical treatment in complex fractures is associated with migrated femoral head and extensive acetabular defects requiring complex acetabular reconstruction. 相似文献9.

Background
We aimed to compare in-hospital postoperative complications (IHPC) and in-hospital mortality between patients with and without type 2 diabetes mellitus (T2DM) undergoing primary total hip arthroplasty (THA) and total knee arthroplasty (TKA).Methods
We analyzed data from the Spanish National Hospital Discharge Database, 2010-2014. We selected patients who had undergone THA (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 81.51) and TKA (code 81.54). Diabetic patients with THA and TKA were matched by year, age, sex, and the comorbidities included in the modified Elixhauser Comorbidity Index with a nondiabetic patient.Results
We identified 115,234 THA patients and 195,355 TKA patients, 12.4% and 15.6% with T2DM, respectively. We matched 10,777 and 26,640 pairs of diabetic and nondiabetic patients. In T2DM patients who had undergone THA, the incidence of urinary tract infection was higher than in nondiabetic patients (1.50% vs 1.09%, P = .007), as was that of “any IHPC” (9.68% vs 8.98%, P = .038). In patients who had undergone TKA, the incidence of postoperative anemia was significantly higher in diabetic patients (4.90% vs 4.53, P = .040), as was that of urinary tract infection (0.80% vs 0.53%, P = .025) and “any IHPC” (7.30% vs 6.76%, P = .014). In both procedures, mean length of hospital stay was significantly higher in diabetic patients; for TKA, in-hospital mortality was higher in diabetic patients (0.09% vs 0.02%, P = .002). Previous comorbidities, age, and obesity predict a higher incidence of IHPC among diabetic patients.Conclusions
This study confirms the higher risk of IHPC among T2DM patients after joint arthroplasty. IHPC may result in a higher risk of mortality in patients undergoing TKA. 相似文献10.

Background
The purpose of this study was to compare risks for revision and short-term complications after total joint arthroplasty (TJA) in matched cohorts of morbidly obese patients, receiving and not receiving prior bariatric surgery.Methods
Patients undergoing elective TJA between 1997 and 2011 were identified in a New York Statewide database, analyzing total knee arthroplasty (TKA) and total hip arthroplasty (THA) separately. Propensity scores were used to match morbidly obese patients receiving and not receiving bariatric surgery prior to TJA. Cox proportional hazard modeling assessed revision risk. Logistic regression evaluated odds for complications.Results
For TKA, 2636 bariatric surgery patients were matched to 2636 morbidly obese patients. For THA, 792 bariatric surgery patients were matched to 792 morbidly obese patients. Matching balanced all covariates. Bariatric surgery reduced co-morbidities prior to TJA (TKA P < .0001; THA P < .005). Risks for in-hospital complications were lower for THA and TKA patients receiving prior bariatric surgery (odds ratio [OR] 0.25, P < .001; and OR = 0.69, P = .021, respectively). Risks for 90-day complications were lower for TKA (OR 0.61, P = .002). Revision risks were not different for either THA (P = .634) or TKA (P = .431), nor was THA dislocation risk (P = 1.000).Conclusion
After accounting for relevant selection biases, bariatric surgery prior to TJA was associated with reduced co-morbidity burden at the time of TJA and with reduced post-TJA complications. However, bariatric surgery did not reduce the risk for revision surgery for either TKA or THA. 相似文献11.

Background
In patients with systemic lupus erythematosus (SLE), persistent joint activity and treatment with glucocorticoids are associated with musculoskeletal complications. About 30% of these patients become candidates for surgical treatment. The aim of this study was to evaluate postoperative outcomes after total hip arthroplasty (THA) in SLE patients.Methods
We performed a retrospective cohort study at a tertiary care center in Mexico City between 1995 and 2013. All patients with SLE who underwent THA during that period were included (n = 58). They were compared with 2 control groups, one from another inflammatory arthropathy (rheumatoid arthritis, n = 58) and other noninflammatory (osteoarthritis, n = 58), matched by gender and date of surgery. The primary outcome was the frequency of postoperative complications during follow-up.Results
We included 174 patients who underwent THA during the study period. Patients with SLE were younger (P < .0001), had a longer hospitalization stay (P = .001), and required more transfusions (P = .004). Global complications in THA in patients with SLE were more prevalent than rheumatoid arthritis (36.2% vs 15.5%, P = .029) and osteoarthritis (36.2% vs 5.1%, P < .0001) patients. After multivariate analysis, risk factors for THA complications were: SLE (hazard ratio 2.8, 95% confidence interval 1.2-6.8; P = .018) and low postoperative hemoglobin (hazard ratio 0.77, 95% confidence interval 0.73-0.83; P < .0001). Long-term complications after THA were similar among groups.Conclusion
This is the largest single-center study regarding clinical outcomes after THA in SLE patients. Our data suggest that SLE is an independent risk factor for adverse postoperative outcomes, mainly immediate complications, but the long-term outcome is good enough to offer surgical treatment that will improve quality of life. 相似文献12.

Background
Periprosthetic femur fractures after primary and revision total hip arthroplasty (THA) are one of the most common long-term reasons for reoperation after THA. Previous investigations have analyzed the incidence and risk factors of these fractures. No previous study, however, has analyzed a variation in periprosthetic femur fractures between meteorologic seasons. The aim of this study was to compare the incidence of periprosthetic femur fractures after primary and revision THAs depending on the meteorologic season.Methods
We identified 8920 patients (10,672 hips) who underwent primary THAs and 1830 patients (1998 hips) who underwent revision THAs at our institution between 1995 and 2011. All patients resided in the Upper Midwest at the time of surgery. Patients who experienced periprosthetic femur fractures were identified and categorized based on the meteorologic season. A Cox model was used to assess the association of seasonality with the risk of fracture.Results
During the study period, 165 primary THAs and 80 revision THAs sustained a periprosthetic femur fracture. Using winter as a reference, the risk of a periprosthetic femur fracture after primary THA was not statistically higher in the spring (hazard ratio [HR] = 1.3; P = .2), autumn (HR = 1.4; P = .2), and summer (HR = 1.415; P = .1). Similarly, the risk of periprosthetic femur fracture after revision THA was not statistically higher in the spring (HR = 0.9; P = .6), autumn (HR = 0.6; P = .1), and summer (HR = 0.9; P = 1.0).Conclusion
The risk of periprosthetic femur fracture after primary and revision THA does not significantly differ between meteorologic seasons. 相似文献13.

Background
This study assessed the correlation among the patients' perception of the leg length discrepancy (LLD) after total hip arthroplasty (THA) and the anatomical and functional leg length, pelvic and knee alignments, and foot height.Methods
Patients without significant spinal pathology or previous spine or lower extremity surgery who underwent primary THA (101 patients) were evaluated using EOS images obtained in standing position. All 3-dimensional measures were evaluated and compared for the repeatability and reproducibility and correlation with patients' perception of leg length.Results
In our study, the anatomical femoral length (odds ratio [OR] 0.9, P = .732) did not correlate with patients' perception of the LLD, but other variables like the distance from the middle of the tibial plafond to ground (OR 14.3, P = .003), sagittal knee alignment (OR 1.07, P = .021), and pelvic obliquity (OR 1.05, P = .021) were correlated with the patients’ perception of LLD.Conclusion
The LLD is a multifactorial complication. We found that the anatomical femoral length as the factor that can be modified with THA technique or choice of prosthesis is not the only important factor. We recommend comprehensive physical examination to investigate spinal deformities, pelvic obliquity, abductor muscle weakness, sagittal and coronal knee alignment, and foot deformity in patients who complain of LLD after THA. 相似文献14.

Background
The coexistence of degenerative hip disease and spinal pathology is not uncommon with the number of surgical treatments performed for each condition increasing annually. The limited research available suggests spinal pathology portends less pain relief and worse outcomes after total hip arthroplasty (THA). We hypothesize that primary THA patients with preexisting lumbar spinal fusions (LSF) experience worse early postoperative outcomes.Methods
This study is a retrospective matched cohort study. Primary THA patients at 1 institution who had undergone prior LSF (spine arthrodesis-hip arthroplasty [SAHA]) were identified and matched to controls of primary THA without LSF. Early outcomes (<90 days) were compared.Results
From 2012 to 2014, 35 SAHA patients were compared to 70 matched controls. Patients were similar in age, sex, American Society of Anesthesiologist score, body mass index, and Charlson Comorbidity Index. SAHA patients had higher rates of complications (31.4% vs 8.6%, P = .008), reoperation (14.3% vs 2.9%, P = .040), and general anesthesia (54.3% vs 5.7%, P = .0001). Bivariate analysis demonstrated SAHA to predict reoperation (odds ratio, 5.67; P = .045) and complications (odds ratio, 4.89; P = .005). With the numbers available, dislocations (0% vs 2.8%), infections (0% vs 8.6%), readmissions, postoperative walking distance, and disposition only trended to favor controls (P > .05). Comparing controls to SAHA patients with <3 or ≥3 levels fused, longer fusions had increased cumulative postoperative narcotic consumption (mean morphine equivalents, 44.3 vs 46.9 vs 169.4; P = .001).Conclusion
Patients with preexisting LSF experience worse early outcomes after primary THA including higher rates of complications and reoperation. Lower rates of neuraxial anesthesia and increased narcotic usage represent potential contributors. The complex interplay between the lumbar spine and hip warrants attention and further investigation. 相似文献15.

Background
Pseudotumors are a common finding in metal-on-metal (MoM) total hip arthroplasty (THA) and resurfacing hip arthroplasty (RHA). However, information on pseudotumors in metal-on-polyethylene (MoP) THA is limited.Methods
One hundred eleven patients with 148 hip articulations—30 MoM THA, 47 MoM RHA, and 71 MoP THA—participated in a cross-sectional study at mean 7.1 (range: 0.2-21.5) years postoperatively. Patients were evaluated with metal artifact reducing sequence magnetic resonance imaging, measurements of metal ions, clinical scores of Harris Hip Score, Oxford Hip Score, the Copenhagen Hip and Groin Outcome Score, and conventional radiographs.Results
Pseudotumors were present in 13 of 30 (43%) MoM THA, 13 of 47 (28%) MoM RHA, and 29 of 71 (41%) MoP THA patients, which was a similar prevalence (P = .10). The prevalence of mixed or solid pseudotumors was significantly higher in patients with MoP THA (n = 10) compared to MoM THA (n = 3) and MoM THA (n = 0), (P = .01). Hips with a mixed or solid pseudotumor had significantly poorer scores of Harris Hip Score (P = .01) and OHS (P = .002) and higher metal ion levels of cobalt (P = .0009) compared to hips without a pseudotumor or with a cystic pseudotumor.Conclusion
Pseudotumors have primarily been associated with MoM hip articulations, but we found a similar pseudotumor prevalence in MoP THA, which is the most common bearing worldwide. Mixed or solid pseudotumors were more often seen in MoP THA compared with MoM hip articulations, and patients with a mixed or solid pseudotumor had poorer clinical scores and higher metal ion levels than patients without a pseudotumor or with a cystic pseudotumor. 相似文献16.

Background
Primary total hip arthroplasty (THA) and conversion THA may result in substantial blood loss, sometimes necessitating transfusion. Despite the complexities of the latter, both are grouped in the same category for quality assessment and reimbursement. This study's purpose was to compare both blood loss and transfusion risk in primary and conversion THA and identify their associated predictors.Methods
A total of 1616 patients who underwent primary and conversion THA at a single hospital from 2009-2013 were reviewed (primary THA = 1575; conversion THA = 41). Demographics, comorbidities, and perioperative data were collected from electronic records. Blood loss was calculated using a validated method. Transfusion triggers were based on standardized criteria. Separate multivariable regression models for blood loss and transfusion were performed.Results
Conversion THA patients were younger (P = .002), had lower age-adjusted Charlson scores (P = .006), longer surgeries (P < .001), higher blood loss (P < .001), and more transfusions (P < .001). Primary and conversion THA groups were different in terms of surgical approach (P < .001), anesthesia type (P = .002), and venous thromboembolism prophylaxis (P = .01). Compared to primary THA, conversion THA had an average 478.9 mL higher blood loss (P = .003) and increased adjusted odds ratio of 3.2 (P = .019) for transfusion.Conclusion
Conversion THA leads to higher blood loss and transfusion compared with primary THA. These differences were quantified in the present study and showed consistent results between the 2 metrics. The differences between these procedures should be addressed during quality assurance because conversion THA is associated with higher resource utilization, which is important in the allocation of resources and tiered reimbursement strategies. 相似文献17.

Background
A significant number of patients who undergo hip arthroscopy will subsequently undergo total hip arthroplasty (THA) or hip resurfacing arthroplasty (HRA), although limited evidence exists regarding effects of prior hip arthroscopy on the outcomes of these procedures.Methods
Of 5091 patients who underwent hip arthroscopy, we identified 69 patients who underwent subsequent THA (46) or HRA (23). Patients were matched to patients with no history of hip arthroscopy. Preoperative and 2-year postoperative Hip disability and Osteoarthritis Outcome Score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Short Form-12, Lower Extremity Activity Scale score, and satisfaction surveys were compared.Results
Patients who underwent THA with history of arthroscopy had lower postoperative Hip disability and Osteoarthritis Outcome Score Pain (82 ± 16 vs 93 ± 9, P = .003), Stiffness (85 ± 16 vs 93 ± 15, P = .01), Sports and Recreation (71 ± 22 vs 88 ± 18, P = .003), Quality-of-Life (65 ± 22 vs 86 ± 11, P < .0001), WOMAC Pain (86 ± 16 vs 93 ± 15, P = .03), WOMAC Stiffness (80 ± 21 vs 88 ± 17, P = .05), and Short Form-12 Physical Component Scores (48 ± 11 vs 54 ± 6, P = .008). They were less likely to be “very satisfied” after arthroplasty (71% vs 89%, P = .0008).Conclusion
Hip arthroscopy before hip arthroplasty is associated with slightly lower results in several patient-reported outcomes. These results are relevant when assessing patients for hip arthroscopy and when counseling prospective arthroplasty patients with history of arthroscopy. 相似文献18.

Background
Periprosthetic joint infection (PJI) is a potentially deadly complication of total joint arthroplasty. This study was designed to address how the incidence of PJI and outcome of treatment, including mortality, are changing in the population over time.Methods
Primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) patients with PJI from the 100% Medicare inpatient data set (2005-2015) were identified. Cox proportional hazards regression models for risk of PJI after THA/TKA (accounting for competing risks) or risk of all-cause mortality after PJI were adjusted for patient and clinical factors, with year included as a covariate to test for time trends.Results
The unadjusted 1-year and 5-year risk of PJI was 0.69% and 1.09% for THA and 0.74% and 1.38% for TKA, respectively. After adjustment, PJI risk did not change significantly by year for THA (P = .63) or TKA (P = .96). The unadjusted 1-year and 5-year overall survival after PJI diagnosis was 88.7% and 67.2% for THA and 91.7% and 71.7% for TKA, respectively. After adjustment, the risk of mortality after PJI decreased significantly by year for THA (hazard ratio = 0.97; P < .001) and TKA (hazard ratio = 0.97; P < .001).Conclusion
Despite recent clinical focus on preventing PJI, we are unable to detect substantial decline in the risk of PJI over time, although mortality after PJI has declined. Because PJI risk appears not to be changing over time, the incidence of PJI is anticipated to scale up proportionately with the demand for THA and TKA, which is projected to increase substantially in the coming decade. 相似文献19.

Background
Advancements in treating hematologic malignancies have improved survival, and these patients may be part of the growing population undergoing total hip arthroplasty (THA). Therefore, the purpose of this study was to evaluate the perioperative outcomes of THA in patients with hematologic malignancies.Methods
The Nationwide Inpatient Sample identified patients who underwent THA from 2000 to 2011 (n = 2,864,412). Patients diagnosed with any hematologic malignancy (n = 18,012) were further stratified into Hodgkin disease (n = 786), non-Hodgkin lymphoma (n = 5062), plasma cell dyscrasias (n = 2067), leukemia (n = 5644), myeloproliferative neoplasms (n = 3552), and myelodysplastic syndromes (n = 1082). Propensity matching for demographics, hospital characteristics, and comorbidities identified 17,810 patients with any hematologic malignancy and 17,888 controls; additional matching was performed to compare hematologic malignancy subtypes with controls. Multivariate regression was used to analyze surgical and medical complications, length of stay (LOS), and costs.Results
Compared to controls, hematologic malignancies increased the risk of any surgery-related complication (odds ratio [OR], 1.4; P < .0001) and any general medical complication (OR, 1.47; P < .0001). Additionally, hematologic malignancies were associated with an increase in LOS (0.16 days; P = .004) and increased costs ($1,101; P < .0001).Conclusion
Patients with hematologic malignancies undergoing THA have an increased risk of perioperative complications, longer LOS, and higher costs. The risk quantification for adverse perioperative outcomes in association with increased cost may help to design different risk stratification and reimbursement methods in such populations. 相似文献20.
