Abstract
Background Total knee arthroplasty (TKA) has become a common surgical intervention for human immunodeficiency virus (HIV)-positive patients who develop osteonecrosis of the knee. This paper summarized existing literature regarding the outcomes of HIV-positive patients undergoing TKA in 4 subsections: (1) complications; (2) survivorship analyses; (3) patient-reported outcomes; and (4) infections. Methods A review of PubMed was performed, searching for articles focused on HIV-positive patients undergoing TKA. There were 6 reports selected, containing 4765 HIV-positive patients, and data regarding the various domains was tabulated and analyzed. To ensure article quality, a methodology score and level of evidence were determined for selected studies. Results Complication rates for HIV-positive patients were low, with a larger study reporting that 7.8% of HIV-positive patients developed a complication in comparison to 8% of HIV-negative patients. Survivorship analyses showed similar results, with a study reporting implant survivorship of 98% for HIV-positive and 99% for HIV-negative patients. There were no differences in patient-reported outcomes; HIV-positive patients improved from baseline with respect to the mean Knee Society objective and mean Knee Society functional scores, and the University of California, Los Angeles self-reported activity levels. The infection rate for HIV-positive patients was low, with a larger database study reporting that 0.6% of HIV-positive patients developed a wound infection in comparison to 0.4% of HIV-negative patients. Conclusions A TKA is an effective treatment for HIV-positive patients who develop osteonecrosis of the knee. Results showed similar patient-reported outcomes, implant survivorships, revisions, and complication rates when compared to non-HIV patients.

Abstract
Periprosthetic joint infection (PJI) is a major complication of total joint arthroplasty. Even with current treatments, failure rates are unacceptably high with a 5-year mortality rate of 26%. Majority of the literature in the field has focused on development of better biomarkers for diagnostics and treatment strategies including innovate antibiotic delivery systems, antibiofilm agents, and bacteriophages. Nevertheless, the role of the immune system, our first line of defense during PJI, is not well understood. Evidence of infection in PJI patients is found within circulation, synovial fluid, and tissue and include numerous cytokines, metabolites, antimicrobial peptides, and soluble receptors that are part of the PJI diagnosis workup. Macrophages, neutrophils, and myeloid-derived suppressor cells (MDSCs) are initially recruited into the joint by chemokines and cytokines produced by immune cells and bacteria and are activated by pathogen-associated molecular patterns. While these cells are efficient killers of planktonic bacteria by phagocytosis, opsonization, degranulation, and recruitment of adaptive immune cells, biofilm-associated bacteria are troublesome. Biofilm is not only a physical barrier for the immune system but also elicits effector functions. Additionally, bacteria have developed mechanisms to evade the immune system by inactivating effector molecules, promoting killing or anti-inflammatory effector cell phenotypes, and intracellular persistence and dissemination. Understanding these shortcomings and the mechanisms by which bacteria can subvert the immune system may open new approaches to better prepare our own immune system to combat PJI. Furthermore, preoperative immune system assessment and screening for dysregulation may aid in developing preventative interventions to decrease PJI incidence.

Abstract
With improved treatment for human immunodeficiency virus (HIV), the demand for total knee arthroplasty (TKA) in this population has increased. Studying the relationship between HIV and postoperative complications following TKA will allow orthopaedic surgeons to accurately assess their patients' surgical risk and provide appropriate counseling. This study aims to understand how HIV impacts surgical and medical complications following TKA for osteoarthritis (OA). Patients identified in a national insurance database who underwent TKA for OA from 2010 to 2019 were divided into three cohorts: no HIV, asymptomatic HIV, and acquired immunodeficiency syndrome (AIDS). Univariate and multivariable regression analyses were performed to determine 90-day postoperative complications as well as 2-year surgical complications (revision surgery, prosthetic joint infection, aseptic loosening, and manipulation under anesthesia). A total of 855,373 patients were included, of whom 1,338 had asymptomatic HIV and 268 had AIDS. After multivariable regression analysis, patients with HIV had no difference in 2-year surgical complications relative to the control cohort. Within 90 days postoperatively, patients with asymptomatic HIV had increased odds of arrhythmia without atrial fibrillation and lower odds of anemia. Patients with AIDS had increased odds of anemia and renal failure. Patients with HIV and AIDS are at an increased risk for developing 90-day medical complications and 2-year surgical complications. However, after accounting for their comorbidities, the risk of 90-day complications was only mildly increased and the risk of 2-year surgical complications approximated the control cohort. Surgeons should pay particular attention to these patients' overall comorbidities, which appear to be more closely associated with postoperative risks than HIV status alone. Level of evidence: III.

Abstract
Patients with human immunodeficiency virus (HIV) are at higher risk for orthopedic related diseases due to dysregulation in bone metabolism and metabolic effects related to their medication regimen. Furthermore, the rate of hip arthroplasty in HIV patients is increasing. With the recent changes in THA methodologies and improvements in HIV treatment, there is a need for updated research analyzing hip arthroplasty outcomes in this high-risk patient population. In this study, we used a national database to evaluate postoperative outcomes in HIV patients undergoing THA compared to THA patients without HIV. We use a propensity algorithm to create a cohort of 493 HIV negative patients for matched analysis. Among the 367,894 THA patients included in this study, 367,390 patients were HIV negative and 504 were HIV positive. The HIV cohort had a lower mean age (53.34 vs 65.88, p < 0.001), lower proportion of females (44% vs 76.4%, p < 0.001), lower incidence of diabetes without complications (5% vs 11.1%, p < 0.001) and a lower incidence of obesity (0.544 vs 0.875, p = 0.002). In the unmatched analysis, the incidence of acute kidney injury (4.8% vs 2.5%, p = 0.004), pneumonia (1.2% vs 0.2%, p = 0.002), periprosthetic infection (3.6% vs 1%, p < 0.001), and wound dehiscence (0.6% vs 0.1%, p = 0.009) were higher in HIV cohort, most likely due to inherent demographic variances present in the HIV population. In the matched analysis, the rates of blood transfusion (5.0% vs 8.3%, p = 0.041) were lower in the HIV cohort. Other post-operative variables, such as rates of pneumonia, wound dehiscence, and surgical site infections were not statistically significant between the HIV positive population and HIV negative matched cohort. Our study found similar rates of postoperative complications in HIV positive and HIV negative patients. The rate of blood transfusions in HIV positive patients was also noted to be lower. Our data suggests that THA is a safe procedure in patients infected with HIV.

Abstract
Introduction Human immunodeficiency virus (HIV) is a retrovirus that can cause acquired immunodeficiency syndrome (AIDS). Total knee arthroplasty (TKA) in HIV-positive patients has not been well documented in the current literature. Thus, this study aimed to examine the early postoperative outcomes and complications of HIV-positive TKA patients as compared to TKA patients who are HIV-negative patients by utilizing the National Inpatient Sample (NIS) database. Methods Admissions data for TKA and HIV were analyzed from the NIS database using ICD-10-CM diagnosis codes. An extensive array of preoperative and postoperative variables was compared among HIV positive TKA patients and HIV negative TKA patients. An unmatched analysis and a matched analysis using a 1:1 propensity match algorithm were conducted to compare the two groups. Results The average age of the HIV-positive group was lower than the HIV-negative group (59.0 vs 66.7, p < 0.001). The HIV-positive group had a smaller percentage of females (38.4% vs 61.5%, p < 0.001) and a lower incidence of tobacco-related disorders than the HIV-negative group (10.3% vs 15.8%, p = 0.032). The HIV-positive group had a longer mean length of stay (3.0 days vs 2.4 days, p < 0.001) and a greater mean total charge incurred (90,780.25 vs 64,801.55, p < 0.001). In the unmatched analysis, the incidence of acute renal failure (6.4% vs 2%, p < 0.001), transfusions (3.9% vs 1.5%, p = 0.004), and periprosthetic joint infection (3% vs 1%, p = 0.007) was higher in HIV positive group. The matched analysis showed a higher incidence of acute renal failure group (6.4% vs 0.5%, p = 0.01) and transfusions (3.9% vs 5%, p = 0.01) in the HIV-positive but a statistically insignificant difference in the rate of periprosthetic joint infection (3% vs 1%, p = 0.153). Conclusion HIV/AIDS is associated with an increased incidence of acute renal failure and transfusions, as well as a longer length of stay and higher incurred costs in TKA patients.

Abstract
INTRODUCTION Human immunodeficiency virus (HIV) positive patients are at high risk for osteonecrosis along with age-related osteoarthritis, resulting in a high number of joint reconstruction surgeries at younger ages in these immunosuppressed patients. Few previous studies have reported on patient outcomes in HAART (highly active antiretroviral therapy) compliant patients undergoing primary arthroplasty. The aim of this study is to report one institution's overall rate of complications and revision in HAART-compliant patients after primary hip and knee arthroplasty. METHODS A retrospective chart review was performed spanning a 4 year period. This study included 50 primary joint arthroplasty patients diagnosed with HIV including 13 TKA (total knee arthroplasty) and 37 THA (total hip arthroplasty) with a prior diagnosis of HIV infection. Preoperative CD4 count and viral loads were recorded. Charts were reviewed for post-operative complications including infection and revision. RESULTS The were a total of 11 postoperative complications (22%). There were 3 cases (6%) of soft tissue infection, 3 cases (6%) of implant loosening, 2 cases (4%) of dislocation, 1 case (2%) of lower extremity weakness, 1 case (2%) of venous thrombosis, and 1 case (2%) of arthrofibrosis. Of all patients, there were 6 cases of revision in this cohort (12%), 5 of which were aseptic etiology. All 3 infected patients had a history of IVDU. Two of these infected patients resolved with IV antibiotics while 1 underwent two-stage revision (2%). Patients that experienced post-operative complications had significantly elevated preoperative CD4 levels (983 versus 598, p = 0.003). CONCLUSION Arthroplasty is a viable option for HAART-compliant patients. Most previous studies showing a higher risk for deep tissue infection and revision in HIV patients have not accounted for modern HAART. Our results show that compliance with HAART has vastly improved the outcomes of arthroplasty in these patients, while a history of IVDU is likely the largest risk factor for infection in this population.

Abstract
Introduction Significant advancements in human immunodeficiency virus (HIV) treatment have led to an increasing life expectancy among patients living with HIV (PLWH). Given this rise in life expectancy, as well as the ability to lead a more active lifestyle, the rate of total joint arthroplasty (TJA) in this population is increasing. Unfortunately, the current medical literature surrounding the safety and efficacy of TJA in this patient population is indeterminant. Therefore, the purpose of this study was to determine if optimization of PLWH prior to TJA would result in any changes in the incidence of postoperative complications and hospital length of stay (LOS) when compared to historically reported data. Materials and methods A retrospective study was performed of all PLWH 18 years and older who underwent either a primary total knee arthroplasty (TKA) or total hip arthroplasty (THA) between 2009 and 2019 at our academic institution. Medical records were reviewed for each patient to assess demographics, comorbidities, preoperative laboratory studies, operative details, length of hospital stay, complications, and follow-up time. Patients were optimized using our institution's current optimization guidelines: body mass index (BMI) less than 40 kg/m2, hemoglobin >12 g/dL, no tobacco use within 30 days of surgery, albumin >3.5 g/dL. Independent-sample t-tests and Pearson's chi-square tests were used to evaluate the continuous and categorical variables, respectively. Results This study included 47 TJA in PLWH, including 14 TKA and 33 THA. Out of the 47 patients, 13 (27.7%) were fully optimized for all four variables: BMI, hemoglobin, non-smoking status, and albumin. There was no significant difference between the group of PLWH that was completely optimized and the group that was not in any patient characteristics, preoperative labs, intraoperative variables, or postoperative variables, including length of hospital stay and complications. A larger proportion of patients not completely optimized was found to be active smokers (p=0.0003). All complications occurred in cases in which the patients were not fully optimized. Subgroup analysis of PLWH, who were completely optimized, showed an average LOS of 4.3+/-1.5 days following TKA and 2.9+/-1.1 days following THA. Subgroup analysis of PLWH not completely optimized showed that each case was optimized for at least one variable and that those optimized for albumin had the largest (12.2%) number of complications. Conclusion PLWH can achieve a low rate of complications and LOS similar to that of the general population if medically and nutritionally optimized. Additional research is necessary to reveal well-defined parameters for achieving a higher rate of optimization prior to surgery in this important patient population.

Abstract
BACKGROUND Several studies reported on periprosthetic infection after primary THA in HIV-positive patients, but very few showed the results of its revision. OBJECTIVE The aim was to compare primary and secondary clinical outcomes after revision arthroplasty for hip joint infection in matched groups of HIV-infected and HIV-negative patients. METHODS Using the hospital database, thirteen HIV-positive patients (13 infected hips) and thirteen HIV-negative patients of the matched control group (13 infected hips) were identified and their records were studied retrospectively. They underwent revision surgery aimed at infection arrest and total hip replacement due to infection developed after primary THA or infected spacers. Harris Hip Score, reinfection rate, limb shortening, and definite outcomes were evaluated with Wilcoxon, Mann-Whitney, and Chi-squared tests. RESULTS AND DISCUSSION Spacers with antibiotics were implanted in patients of both groups at the first step of revision, except one HIV-infected patient who had resection arthroplasty. The mean follow-up was 29.4±2.7 and 33.±2.9 months for the HIV-group and control group, respectively. Three patients of the HIV-group completed two-stage revision arthroplasty versus ten patients from the control group. Re-infection rate was higher in the HIV-group. At final follow-ups, the mean HHS was significantly different (53±3.2 points in the HIV-group versus 79.14±3.1 points in the control group) along with limb length discrepancy (3.71±0.43 versus 1.4±0.32). CONCLUSION Both primary and secondary clinical outcomes of revision arthroplasty for hip joint infection in HIV-positive patients were significantly worse than in the matched group of HIV-negative patients. Revisions in HIV-positive group resulted in a higher reinfection rate, a small number of definite two-stage revisions, and lower functional scores.

Abstract
BACKGROUND Anti-retroviral therapy (ART) remains the cornerstone of decreasing morbidity and mortality in human immunodeficiency virus (HIV) patients. However, a large study comparing HIV patients taking ART prior to total knee arthroplasty (TKA) is lacking. We sought to examine: (1) readmissions; (2) post-operative complications; and (3) revisions in ART-treated or untreated HIV patients compared with a non-HIV population. METHODS We queried a national, all-payer database to identify TKA patients from 2010-2020 (n = 1,393,357). The presence or absence of ART was identified and matched with non-HIV patients based on age, sex, diabetes, obesity, and tobacco status resulting in 889 patients in each cohort. Readmissions, post-operative complications, and revisions were assessed. RESULTS Readmissions were higher among all HIV patients and even higher in those not taking ART, as compared to the matching cohort (4.8 versus 1.6%, p < 0.01). Prosthetic joint infections (PJIs) at 1-year were higher among HIV patients who were either taking ART (4.0%; OR, 1.41 [0.82-2.45]) or not taking ART (5.1%; OR, 2.44 [1.42-4.21]) as compared to non-HIV patients (2.1%, all p < 0.03). Revision rates at 1-year trended higher in HIV patients who were taking ART (2.6%; Odds Ratio (OR), 1.94 [0.96-3.93]) and who did not take ART (3.1%; OR, 2.38 [1.20-4.70]), compared to non-HIV patients (1.3%, all p < 0.09). CONCLUSIONS ART-treated HIV patients are associated with lower readmissions, post-operative complications, and revisions when compared to HIV patients not taking ART. The findings of this study underscore the utility of ART and patient optimization to reduce risk in HIV patients.

Abstract
STUDY DESIGN This was a retrospective cohort studying using a national administrative database. OBJECTIVE The objective of this study was to determine the postoperative complications and quality outcomes of the human immunodeficiency virus (HIV)-positive patients undergoing surgical management for lumbar degenerative disease (LDD). METHODS This study identified patients with who underwent surgery for LDD between 2007 and 2016. Patients were stratified based on whether they were HIV positive at the time of surgery. Multivariate regression was utilized to reduce the confounding of baseline covariates. Patients who underwent 3 or more levels of surgical correction were under the age of 18 years, or those with any prior history of trauma or tumor were excluded from this study. Baseline comorbidities, postoperative complication rates, and reoperation rates were determined. RESULTS A total of 120,167 patients underwent primary lumbar degenerative surgery, of which 309 (0.26%) were HIV positive. In multivariate regression analysis, the HIV-positive cohort was more likely to be readmitted at 30 days [odds ratio (OR)=1.9, 95% confidence interval (CI): 1.2-2.8], 60 days (OR=1.7, 95% CI: 1.2-2.5), and 90 days (OR=1.5, 95% CI: 1.0-2.2). The HIV-positive cohort was also more likely to experience any postoperative complication (OR=1.7, 95% CI: 1.2-2.3). Of the major drivers identified, HIV-positive patients had significantly greater odds of cerebrovascular disease and postoperative neurological complications (OR=3.8, 95% CI: 1.8-6.9) and acute kidney injury (OR=3.4, 95% CI: 1.3-7.1). Costs of index hospitalization were not significantly different between the 2 cohorts ($30,056 vs. $29,720, P=0.6853). The total costs were also similar throughout the 2-year follow-up period. CONCLUSION Patients who are HIV positive at the time of LDD surgery are at a higher risk for postoperative central nervous system and renal complications and unplanned readmissions.

Abstract
In this observational study, we describe the medium-term outcomes of total joint arthroplasty (TJA) in human immunodeficiency virus (HIV)-positive patients in Malawi, a low-income country. With a high prevalence of HIV and increasing arthroplasty rates in low and middle-income countries, understanding the outcomes of TJA in this unique cohort of patients is essential to ensure that surgical practice is evidence-based.

Abstract
Background: Antiretroviral therapy (ART) remains the cornerstone of decreasing morbidity and mortality in patients with human immunodeficiency virus (HIV), but additional information on its impact on total hip arthroplasty (THA) complication rates is needed to mitigate risks postoperatively. Therefore, we sought to examine patients with HIV who were and were not taking ART compared with a cohort without HIV in the setting of primary THA with respect to the following outcomes: length of stay, readmissions, and postoperative infection. Methods: A retrospective database review was performed with PearlDiver for patients who underwent THA from 2010 to 2019 (n = 729,101). Patients with HIV who were and were not taking ART were then identified and were matched with patients without HIV at a 1:1:1 ratio based on age, sex, Charlson Comorbidity Index, diabetes, obesity, and tobacco use, resulting in 601 patients in each cohort. Length of stay, 30-day readmissions, and complications at 90 days and 1 year were analyzed. Continuous outcomes were measured via Student t tests, and categorical outcomes were measured via chi-square analyses. Results: Patients with HIV who were and were not taking ART were found to have similar lengths of stay compared with patients without HIV (range, 4.1 to 4.3 days). Readmission rates were slightly higher in patients with HIV who were taking ART at 4.2% (odds ratio [OR], 1.96 [95% confidence interval (CI), 0.99 to 3.87]) and patients with HIV who were not taking ART at 3.5% (OR, 1.63 [95% CI, 0.81 to 3.30]) compared with patients without HIV at 2.1%. Periprosthetic joint infection rates at 1 year were slightly higher among patients with HIV who were not taking ART at 5.3% (OR, 1.41 [95% CI, 0.82 to 2.45]) compared with patients with HIV who were taking ART at 4.2% (OR, 1.09 [95% CI, 0.61 to 1.94]) and patients without HIV at 3.8%. Conclusions: Patients with HIV who are and are not taking ART are approaching normalization to the general population in the setting of THA. It is important to note that, although complications may have been mitigated by modern therapy, extreme care should be taken while clinically evaluating these patients prior to the surgical procedure given the complexity of their clinical status. The findings of this study underscore the utility of ART and patient optimization to reduce risk in this patient population. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND The impact of CD4+ T-cell count and highly active antiretroviral therapy (HAART) on the rate of surgical site infection (SSI) in patients with human immunodeficiency virus (HIV) undergoing total hip arthroplasty is still unclear. The goals of this study were to assess the rate of perioperative infection at a large tertiary care referral center and to identify risk factors in HIV+ patients undergoing total hip arthroplasty (THA). METHODS This study was a prospective, observational study at a single medical center from 2000-2017. Patients who were HIV+ and underwent THA were followed from the preoperative assessment period, through surgery and for a 2-year follow-up period. RESULTS Sixteen of 144 HIV+ patients (11%) undergoing THA developed perioperative surgical site infections. Fourteen patients (10%) required revision THA within a range of 12 to 97 days after the initial surgery. The patients' mean age was 49.6 ± 4.5 years, and the most common diagnosis prompting THA was osteonecrosis (96%). Patients who developed SSI had a lower waist-hip ratio (0.86 vs. 0.93, p = 0.047), lower high density lipoprotein cholesterol (45.8 vs. 52.5, p = 0.015) and were more likely to have post-traumatic arthritis (12.5% vs. 0%, p = 0.008). Logistic regression analysis demonstrated that current alcohol use and higher waist-hip ratio were significant protectors against infection (p < 0.05). No other demographic, medical, immunologic parameters, or specific HAART regimens were associated with perioperative infection. CONCLUSIONS Immunologic status as measured by CD4+ cell count, HIV viral load, and medical therapy do not appear to influence the development of SSI in HIV+ patients undergoing THA. Metabolic factors and post-traumatic arthritis may influence the increased rate of infection in HIV+ patients following THA.

Abstract
Human immunodeficiency virus (HIV) is a pandemic affecting more than 35 million people worldwide. The aim of this review is to describe the association between HIV and total hip arthroplasty (THA) and assess patient risk factors to optimize functional outcomes and decrease rates of revision. Since the advent of highly active antiretroviral treatment (HAART), HIV-infected patients are living longer, which allows them to develop degenerative joint conditions. HIV and HAART act independently to increase the demand for THA. HIV-positive patients are also more predisposed to developing avascular necrosis (AVN) of the hip and femoral neck fractures due to decreased bone mineral density (BMD). Prior to the widespread implementation of access to HAART in homogenous cohorts of HIV-infected patients undergoing THA, reports indicated increased rates of complications. However, current literature describes equivocal functional outcomes and survival rates after THA in HIV-positive patients controlled on HAART when compared to HIV-negative controls. HIV-infected patients eligible for THA should be assessed for medical co-morbidities and serum markers of disease control should be optimized. Periprosthetic joint infection (PJI) is a leading cause of revision THA, and HIV is a modifiable risk factor. Importantly, the significance is negated once patients are placed on HAART and achieve viral suppression. THA should not be withheld in HIV-infected patients injudiciously. However, HIV is a burgeoning epidemic and all patients should be identified and started on HAART to avoid preventable peri-operative complications.

Abstract
Relevance. There is a limited number of publications reporting outcomes of primary large joint arthroplasty in patients with human immunodeficiency virus (HIV). The authors were unable to find papers on revision arthroplasty in patients with periprosthetic infection. Purpose of the study — to evaluate short term outcomes after revision arthroplasty in HIV-positive patients with periprosthetic infection of the hip and knee joint. Materials and methods. 13 HIV-positive patients with periprosthetic infection of the hip (10 cases) and knee (3 cases) joint underwent treatment in the period from 2015 to 2019. Patients were examined by clinical, laboratory and roentgenological methods. Harris Hip Score and Knee Society Score were used for evaluation prior to and after the surgery. Results. Mean follow up period was 21,4±2,6 months. Successful two-stage treatment was performed in two (15,4%) out of 13 patients with periprosthetic infection. In 5 cases (38,5%) control over infection was achieved by resection arthroplasty, and in one case (7,7%) – by arthrodesis. Five patients (38,5%) refused from interchange of spacer to prosthesis. Mean Harris Hip score demonstrated insignificant increase postoperatively — from 45,3±2,2 to 52,2±4,15 (р = 0,2). Conclusion. Despite following the international protocols for treatment of implant-associated infection the infection recurrence rate in HIV-positive patients in the asymptomatic phase remains very high. Efficiency of twostage treatment using antibacterial spacers in the present group of patients amounted only to 15,4%.

Abstract
Significant advances in the treatment of Human Immunodeficiency Virus (HIV) have occurred in recent times, with life expectancy now approaching the normal population. Therefore, patients with HIV will increasingly be undergoing joint replacement in the future, however concerns remain regarding the complications and outcome in this patient cohort. The aim was to assess the outcome of total hip and knee arthroplasty in HIV-infected patients. A systematic search of the literature using MOOSE reporting guidelines was performed to assess the outcome of hip and knee arthroplasty in HIV-infected patients. The primary outcome was infection. Secondary outcome was all-cause revision. The search yielded 552 results, of which 19 met the inclusion criteria, comprising 5.819.412 joint replacements. The overall quality of the studies was poor with significant heterogeneity between the studies. Infection and revision appeared to be more likely to occur in HIV positive patients compared to HIV negative patients. A subgroup analysis of four studies revealed a risk ratio of 3.31 and 2.25 for increase in infection and revision respectively in HIV positive patients. This systematic review and meta-analysis demonstrates an increased risk of infection and revision in HIV infected patients undergoing total hip and knee arthroplasty. However, these findings are based on poor quality evidence in a limited number of studies and need to be interpreted with caution. Further research should concentrate on large, well-designed, prospective studies, that control for co-morbidities and employ standardised outcome measures to allow for direct comparison.

Abstract
BACKGROUND Advancements in the management of human immunodeficiency virus (HIV) now permit HIV-positive patients to have longer life spans, increasing their cumulative risk of developing an advanced degenerative joint disease, necessitating total hip arthroplasty (THA). The purpose of this study was to provide an extended follow-up on a previously published study on a cohort of HIV-positive THA recipients in an effort to confirm the safety and longevity of THA in this population. METHODS This study is a follow-up on a previous study comprised of 41 hips in 31 HIV-positive THA recipients. At this follow-up, 5 patients from the original cohort required contralateral THA. Postoperative complications were recorded up to the patient's last follow-up date. A survivorship analysis was performed using the Kaplan-Meier method with revision THA as the end point. RESULTS Since the last report, 2 additional hips were revised (one for aseptic loosening and one for a periprosthetic fracture), and 5 patients underwent contralateral THA. This resulted in a total of 5 (13.8%) hips requiring revision THA at the latest follow-up. The mean follow-up interval for the original cohort and for the contralateral 5 hips was 78.9 ± 50.2 months and 54.6 ± 45.3 months, respectively. Kaplan-Meier survivorship analysis with revision THA for any reason as the end point demonstrated survivorship of 93% (2 years), 90% (5 years), and 81% (10 and 14 years) after primary THA, respectively. CONCLUSION Our study suggests that it is possible to achieve a low incidence of postoperative infection in HIV-positive THA recipients. In addition, our study demonstrates that non-hemophiliac HIV-positive patients have comparable revision rates to previously published reports on HIV-negative patients of similar age, underscoring the clinical efficacy of highly active antiretroviral therapy.

Abstract
INTRODUCTION Evidence about the optimal timing for total hip replacement (THR) in HIV-positive patients is scant. HYPOTHESIS Preoperative criteria: cluster of differentiation 4 (CD4) counts>200cells/mm3 and an undetectable HIV virus load before THR, improve infection rates, aseptic loosenings, and functional outcomes. MATERIALS AND METHODS We recruited 16 HIV-positive patients who had undergone 25 THRs between 2003 and 2015. None had hemophilia, and none were intravenous drug users (IVDUs). RESULTS Their mean age was 41.2 years (range: 24-60); minimum follow-up was 12 months (mean: 64.6); mean duration of prophylactic antibiotics was 2.9 days (range: 1-5); and mean hospital length of stay was 6.0 days (range: 4-11). No patients were treated with subsequent oral antibiotics. The mean preoperative CD4 count was 464.1±237.0 (range: 235-904)cells/mm3. There were no early superficial surgical site infections, late periprosthetic joint infections, or aseptic loosenings. Post-surgery Harris Hip score was significantly (p<0.001) better. DISCUSSION A preoperative CD4 count>200cell/mm3 and an undetectable HIV virus load might indicate optimal timing for elective THRs in HIV-positive patients without hemophilia and not IVDUs. LEVEL OF EVIDENCE IV, retrospective or historical series.

Abstract
INTRODUCTION Due to advancement in treatment against human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV), the prevalence of this patient population electing to undergo total joint arthroplasty (TJA) is increasing. Current literature is scarce and conflicting especially when evaluating long-term surgical complications. The purpose of this study is to assess the postoperative medical and surgical complications following TJA in these patient populations. METHODS Using a nationwide database between 2005 and 2012, 4 cohorts were created: patients with HIV, HCV, HBV, and HIV and HBV or HCV who underwent TJA. Cohorts were matched to a control group by age, gender, and Charlson Comorbidity Index. Thirty-day and 90-day medical complications and 90-day and 2-year surgical complications were evaluated using odds ratios with 95% confidence intervals. RESULTS Following TJA, patients with HCV or HBV had increased risk of pneumonia, sepsis, joint infection, and revision surgery at 90 days and 2 years. Patients with HIV did not have increased risk of infection at 90 days and 2 years but did have increased risk of revision at 90 days (odds ratio 3.21, 95% confidence interval 1.31-7.84) following total hip arthroplasty. CONCLUSIONS Patients with HIV, HBV, or HCV have an overall increased risk of postoperative medical and surgical complications following TJA. Patients with HBV or HCV are at risk of more complications than patients with HIV especially for infection within 90 days after TJA. Patients with HIV are at risk of mechanical complications but do not appear to be at significant risk for infection following total hip arthroplasty.

BACKGROUND Modern management of human immunodeficiency virus (HIV) infection has afforded patients longevity while increasing the burden of arthroplasty procedures because of the increased risk of osteonecrosis, fragility fractures, and degenerative joint disease. Early publications on hip and knee arthroplasty in HIV-positive patients reported a high risk of complications, although some more recent publications demonstrated acceptable outcomes. Despite the widespread nature of the HIV pandemic, there is a paucity of literature addressing outcomes following joint arthroplasty in infected patients. We pooled available studies to obtain the best evidence regarding the safety of total hip and knee arthroplasty procedures in HIV-positive patients. The studies identified were heterogeneous, precluding a meta-analysis. However, we performed a review of the literature focusing on complications and outcomes. METHODS Twenty-one published English-language articles involving 6,516,186 joints were identified by a systematic review as suitable for inclusion in the study. The articles were analyzed for complication and prosthesis survivorship rates and relative risks. RESULTS An overall complication rate of 3.3% was found across the 19 articles that provided such data. HIV-positive patients had a significantly elevated risk of periprosthetic joint infection, at 7.6%, compared with HIV-negative patients, at 3.3% (relative risk = 2.28, 95% confidence interval = 2.14 to 2.43). Eleven articles were suitable for analysis of prosthesis survivorship, and survivorship rates did not differ significantly between HIV-positive and negative patients. CONCLUSIONS Total hip and total knee arthroplasty appear to be safe procedures with acceptable outcomes in HIV-positive patients. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
BACKGROUND Preoperative identification of patients at risk for periprosthetic joint infection (PJI) following total hip arthroplasty (THA) or total knee arthroplasty (TKA) is important for patient optimization and targeted prevention. The purpose of this study was to create a preoperative PJI risk calculator for assessing a patient's individual risk of developing (1) any PJI, (2) PJI caused by Staphylococcus aureus, and (3) PJI caused by antibiotic-resistant organisms. METHODS A retrospective review was performed of 27,717 patients (12,086 TKAs and 31,167 THAs), including 1,035 with confirmed PJI, who were treated at a single institution from 2000 to 2014. A total of 42 risk factors, including patient characteristics and surgical variables, were evaluated with a multivariate analysis in which coefficients were scaled to produce integer scores. External validation was performed with use of data on 29,252 patients who had undergone total joint arthroplasty (TJA) at an independent institution. RESULTS Of the 42 risk factors studied, 25 were found not to be significant risk factors for PJI. The most influential of the remaining 17 included a previous open surgical procedure, drug abuse, a revision procedure, and human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS). The areas under the curves were 0.83 and 0.84 for any PJI, 0.86 and 0.83 for antibiotic-resistant PJI, and 0.86 and 0.73 for S. aureus PJI in the internal and external validation models, respectively. The rates of PJI were 0.56% and 0.61% in the lowest decile of risk scores and 15.85% and 20.63% in the highest decile. CONCLUSIONS In this large-cohort study, we were able to identify and validate risk factors and their relative weights for predicting PJI. Factors such as prior surgical procedures and high-risk comorbidities should be considered when determining whether TJA is indicated and when counseling patients.

Total knee arthroplasty in patients with a history of illicit intravenous drug abuse. INTERNATIONAL ORTHOPAEDICS 2017; 42:101-107. [PMID: 29032478 DOI: 10.1007/s00264-017-3655-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/21/2017] [Accepted: 09/24/2017] [Indexed: 10/18/2022]
Abstract
PURPOSE Injection drug users are at high risk for both infection with blood-borne pathogens, namely, human immune deficiency virus (HIV), hepatitis-B, -C virus, various bacterial infections, as well as early primary and secondary joint degeneration. When total knee arthroplasty (TKA) is anticipated the risk of septic complications is a major concern. The purpose of this study was to assess the clinical and radiographic outcome of patients with a history of intravenous drug use after total knee arthroplasty. The primary outcome was revision rate. Secondary outcomes were the Western Ontario and McMaster Universities Arthritis Index (WOMAC), Knee Society Score (KSS) and radiographic loosening. METHODS We retrospectively reviewed the records of 1,692 TKA performed or revised in our institution. Data of 18 TKA in 12 patients (11 male, 1 female; average age 42, range 23-62 years) with a history of intravenous opioid abuse were available for final analysis. RESULTS The mean follow up was 125 (range 25-238) months. Seven patients required revision surgery due to periprosthetic joint infection after 62 months (range 5-159): one two staged revision, three arthrodesis and three amputations. The median prosthesis survival was 101 (95%-CI 48-154) months. CONCLUSION Total knee arthroplasty in patients with a history of intravenous drug abuse is associated with major complications, including above-the-knee amputation. If permanent abstinence from intravenous drug abuse is doubtful, other therapeutic options including primary arthrodesis should be considered.

Abstract
BACKGROUND HIV is prevalent worldwide and numerous patients with this diagnosis ultimately may become candidates for TKA. Although some studies have suggested that complications are more common in patients with HIV who undergo TKA, these studies largely were done before the contemporary era of HIV management; moreover, it is unclear whether patients with HIV achieve lower patient-reported outcome scores or inferior implant survivorship. QUESTIONS/PURPOSES We asked whether there were any differences in the outcomes of patients with HIV without hemophilia who undergo TKA compared with a matched control cohort in terms of: (1) patient-reported outcomes; (2) implant survivorship; and (3) complication rates. METHODS Forty-five patients with HIV who had undergone 50 TKAs at three institutions with a minimum followup of 4 years between 2005 and 2011 were identified. An additional three patients were lost to followup before the fourth-year annual visit. All patients with HIV underwent thorough preoperative optimization with their primary care physician and infectious disease specialist. There were 31 men and 14 women with a mean age of 57 years and mean followup of 6 years (range, 4-10 years). These patients were compared with a matched cohort of 135 patients (one-to-three ratio) who did not have HIV and who had undergone a primary TKA by the same surgeons during this same period using the same implant. Matching criteria included patient age (within 2 years), BMI (within 2 kg/m2), surgeon performing TKA, followup (within 6 months), minimum followup of 4 years, sex ratio, and primary diagnosis (degenerative joint disease versus osteonecrosis). Approximately 10% of patients in the matching group had not returned for followup after their sixth annual visit. Outcomes evaluated included The Knee Society objective and function scores, University of California, Los Angeles (UCLA) activity scores, overall implant survivorship (free of revision) using Kaplan-Meier analysis, and complications. With the numbers available, there were no differences in preoperative Knee Society score or UCLA activity scores among the cohorts. RESULTS With the numbers available, there were no differences in the mean Knee Society objective scores between patients with HIV (89 ± 11 points) and the matching cohort (91 ± 14 points) (95% CI, -7 to 3; p = 0.38). There were no differences among the Knee Society functional component as well (88 ± 12 points versus 90 ± 13 points; 95% CI, -6 to 2; p = 0.36) at latest followup. Similarly, there were no differences with the numbers available in the UCLA activity scores (6 ± 5 points [range, 4-7] versus 6 ± 7 points [range, 4-8]; p = 0.87) between the cohorts. With the numbers available, Kaplan-Meier analysis showed no significant difference in the overall implant survivorships between patients with HIV (98%; 95% CI, 94%-99%) compared with the matching group (99%; 95% CI, 98%-100%; p = 0.89). Postoperative complications were also comparable between the two groups. CONCLUSIONS With the numbers available, we found that patients with HIV had no differences in clinical scores and implant survivorship compared with patients without the disease at mid-term followup. We believe practitioners should not be reluctant to perform TKA on this patient population. However, we believe the preoperative optimization process is crucial to achieving good outcomes and minimizing the risk of complications. Future comparative studies should have longer followup and a larger sample size with greater power to determine if there are differences in complications and implant survivorship.

Abstract
BACKGROUND Highly active antiretroviral therapy (HAART) has changed the face of human immunodeficiency virus (HIV) and allowed patients to live for many decades. HIV and HAART are known risk factors for osteonecrosis of bone, osteopenia, and osteoporosis. Therefore, the demand for total joint arthroplasty (TJA) in HIV-infected patients is on the rise. We attempted to determine whether modern treatments for HIV have impacted the rate of periprosthetic joint infection (PJI). METHODS Conducting a systematic review, 25 studies with a total of 722 TJAs were identified. We extracted data on rates of PJI after primary TJA in HIV-infected patients with and without hemophilia and data on administration of HAART at the time of arthroplasty. RESULTS Three hundred eighty-one TJAs were performed in 293 patients with HIV infection without hemophilia. The follow-up ranged between 1.5 months and 11 years. Nine patients developed PJI. In patients with both HIV and hemophilia, 341 primary TJAs were performed. Forty-five received treatment for PJI. Follow-up ranged between 1 year and 26 years. Rates of PJI were 2.28% and 10.98% for HIV-only patients and patients with HIV and hemophilia, respectively. This difference was statistically significant (P < .0001) with a 5.28 odds ratio for hemophilia. HAART was associated with fewer infections overall (odds ratio, 0.12). CONCLUSION The rates of PJI after TJA in HIV-only patients are lower than those in patients with both HIV and hemophilia. Treatment of patients with HAART and optimization of underlying comorbidities appears to lower the rate of PJI in this patient population.

Abstract
Infection is a major cause of orthopedic implant failure. There are few studies assessing both tissue cell and bacterial adherence on common orthopedic implant materials in a co-culture environment. An in vitro co-culture model was created using K12 osteosarcoma cells and Staphylococcus aureus in a medium incubated over metal disks for 48 h. The results showed that, in the presence of S. aureus, there were fewer osteosarcoma cells attached to the disks for all substrata tested. There were significantly more osteosarcoma cells adhering to the cobalt chrome than the stainless steel and titanium disks. Overall, in the presence of osteosarcoma cells, there were more bacteria adhering to the disks for all the substrata tested, with significantly more bacteria adhering to the stainless steel disks compared to cobalt chrome and titanium disks. Scanning electron microscopy verified that osteosarcoma cells and bacteria were adherent to the metal disks after incubation for 48 h. Furthermore, the observation that more bacteria were in the co-culture than in the control sample suggests that the osteosarcoma cells serve as a nutrient source for the bacteria. Future models assessing the interaction of osteogenic cells with bacteria on a substratum would be improved if the model accounted for the role of the immune system in secondary bone healing.

Abstract
➤Advances in combined antiretroviral therapy (cART) in recent years have transformed HIV infection into a chronic disease when treatment is available, increasing a patient's life expectancy and the chances that orthopaedic surgeons will encounter such patients in their clinical practice.➤Musculoskeletal manifestations in patients with HIV infection are common and sometimes are the initial presentation of the disease. Knowledge about neoplasms and associated conditions affecting muscle, bones, and joints is essential for successful management.➤Since the advent of cART, total joint arthroplasty has been shown to be a safe procedure; however, perioperative infection is still a small risk in patients with uncontrolled viral loads or CD4 counts of <400 cells/mm(3).➤With regard to trauma surgery, the rates of early and late infection around implants, as well as union rates, are comparable with those in the HIV-negative population; however, there is an increased risk of pulmonary, renal, and infectious or septic complications in the polytrauma setting.➤Factors such as CD4 count, nutritional status, cART therapy, viral load count, and other comorbidities (hemophilia, infection among intravenous drug users, etc.) should be considered when treating these patients in order to optimize their clinical outcomes.

Abstract
STUDY DESIGN Retrospective database analysis. OBJECTIVE To evaluate outcomes of human immunodeficiency virus (HIV) positive patients after cervical spine surgery. SUMMARY OF BACKGROUND DATA Highly active antiretroviral medications have qualitatively altered the natural history of HIV, thus increasing the number of HIV-positive patients seeking treatment for chronic degenerative conditions. Minimal data exist on HIV patients undergoing degenerative cervical spine surgery. METHODS The Nationwide Inpatient Sample was examined from 2002 to 2011. Hospitalizations were identified using International Classification of Diseases Ninth Revision, Clinical Modification (ICD-9-CM) procedural codes for cervical spine surgery and diagnoses codes for degenerative conditions of the cervical spine, and HIV. Statistical analysis was conducted to evaluate associations between HIV status and perioperative complications. RESULTS A total of 1,602,129 patients underwent degenerative cervical spine surgery, of which 3700 patients (0.23%) had HIV. The prevalence of HIV increased over the study period from 0.19% to 0.33% (P < 0.001). Patients with HIV were younger (48.6 yrs vs. 53.4 yrs, P < 0.001) and more likely to be male (P < 0.001). HIV patients had significantly greater odds of having chronic pulmonary disease, liver disease, and drug abuse. Unadjusted analysis did not reveal increased rate of acute complications among HIV-positive patients compared with negative controls (3.8% vs. 3.7%, P = 0.62). Multivariate analysis did not identify HIV as a significant predictor of complication (odds ratio = 1.04, P = 0.84). HIV was associated with a 1.5 day increased length of stay AND 1.29 fold increase in median costs compared with controls ($14,551 vs. 18,846, P < 0.001). CONCLUSION The prevalence of HIV patients undergoing degenerative cervical spine surgery is increasing. A diagnosis of HIV was not associated with an increased risk of perioperative complication among patients undergoing degenerative cervical spine surgery. Further clinical studies are needed to evaluate predictors of complications among HIV patients and long-term outcomes. LEVEL OF EVIDENCE 4.

Abstract
Using the Nationwide Inpatient Sample, we assess the: (1) demographic trends; (2) complications; and (3) length of hospital stay among total knee arthroplasty (TKA) patients with and without human immunodeficiency virus (HIV). The study population consisted of 2772 patients with HIV and 5,672,314 controls. Patients with HIV were more likely to be younger, male, and nonwhite. Patients with HIV were at an increased risk for perioperative wound infections (OR=2.78; P=0.024), although they were not at an increased risk for overall complications (OR=1.21; P=0.321). Mean length of stay was 17% longer for patients with HIV (P<0.001). Given these findings, orthopedic surgeons should have a low threshold to work up a patient with HIV for a wound infection following TKA.

Abstract
IMPORTANCE Antiretroviral therapy (ART) has converted human immunodeficiency virus (HIV) infection into a chronic condition, and patients now undergo a variety of surgical procedures, but current surgical outcomes are inadequately characterized. OBJECTIVE To compare 30-day postoperative mortality in patients with HIV infection receiving ART with the rates in uninfected individuals. DESIGN, SETTING, AND PARTICIPANTS Retrospective analysis of nationwide electronic medical record data from the US Veterans Health Administration Healthcare System, October 1, 1996, to September 30, 2010. Common inpatient surgical procedures were grouped using the Healthcare Cost and Utilization Project Clinical Classification System to match HIV-infected and uninfected patients in a 1:2 ratio. Data on 1641 patients with HIV infection receiving combination ART who were undergoing inpatient surgery were compared with data on 3282 procedure-matched, uninfected comparators. Poisson regression models of 30-day postoperative mortality were adjusted for procedure year, age, Charlson Comorbidity Index score, hemoglobin level, albumin level, HIV infection, CD4 cell count, and HIV-1 RNA level. MAIN OUTCOMES AND MEASURES All-cause 30-day postoperative mortality. RESULTS The most common procedures in both groups were cholecystectomy (10.5%), hip arthroplasty (10.5%), spine surgery (9.8%), herniorrhaphy (7.4%), and coronary artery bypass grafting (7.0%). In patients with HIV infection, CD4 cell distributions were 80.0% with 200/μL or more, 16.3% with 50/μL to 199/μL, and 3.7% with less than 50/μL; 74.1% of patients with HIV infection had undetectable HIV-1 RNA. Human immunodeficiency virus infection was associated with higher 30-day postoperative mortality compared with the mortality in uninfected patients (3.4% [56 patients]) vs 1.6% [53]); incidence rate ratio [IRR], 2.11; 95% CI, 1.41-3.17; P < .001). CD4 cell count was inversely associated with mortality, but HIV-1 RNA provided no additional information. After adjustment, patients with HIV infection had increased mortality compared with uninfected patients at all CD4 cell count strata (≥500/μL: IRR, 1.92; 95% CI, 1.02-3.60; P = .04; 200-499/μL: IRR, 1.89; 95% CI, 1.20-2.98; P = .01; 50-199/μL: IRR, 2.66; 95% CI, 1.29-5.47; P = .01; and <50/μL: IRR, 6.21; 95% CI, 3.55-10.85; P < .001). Hypoalbuminemia (IRR, 4.35; 95% CI, 2.78-6.81; P < .001) and age in decades (IRR, 1.47; 95% CI, 1.23-1.76; P < .001) were also strongly associated with mortality. CONCLUSIONS AND RELEVANCE Current postoperative mortality rates among individuals with HIV infection who are receiving ART are low and are influenced as much by hypoalbuminemia and age as by CD4 cell status. Human immunodeficiency virus infection and CD4 cell count are only 2 of many factors associated with surgical outcomes that should be incorporated into surgical decision making.

Abstract
BACKGROUND Recent studies have shown successful midterm outcomes after total hip arthroplasty (THA) in patients with human immunodeficiency virus (HIV). However, little data exist on the epidemiology, risk of perioperative complications, and length of stay in patients with HIV receiving THA. QUESTIONS/PURPOSES The purposes of this study were to assess (1) the demographic trends of patients with HIV who underwent primary THA; (2) the differences in the risk of major and minor perioperative complications among patients with and without HIV; and (3) the differences in mean length of hospital stay among patients with and without HIV. METHODS The Nationwide Inpatient Sample was used to compare patients with and without HIV who were admitted for THA between 1998 and 2010 in the United States. We extracted data on each admission's age, sex, race, insurance, and comorbidities. The study population consisted of 2,656,696 patients without HIV and 9275 patients with HIV. RESULTS Patients with HIV were more likely to be younger, be male, not pay with Medicare, and be of a nonwhite race. After controlling for confounding variables, patients with HIV were more likely to have major complications (2.9% [266 of 9275] versus 2.7% [71,952 of 2,656,696]; odds ratio [OR], 1.47; 95% confidence interval [CI], 1.08-2.00; p=0.014) and minor complications (5.2% [483 of 9275] versus 4.8% [127,940 of 2,656,696]; OR, 1.61; 95% CI, 1.29-2.02; p<0.001) compared with patients who did not have HIV. Patients undergoing THA who had HIV also had an increased length of hospital stay compared with patients without HIV (4.31 versus 3.83 days, p<0.001). CONCLUSIONS Given these findings, we believe orthopaedic surgeons should be aware of the potential for longer and more complicated hospital stays after THA among patients with HIV. However, the modest increase in risk of adverse outcomes does not cause us to recommend against THA for patients with HIV who otherwise meet reasonable surgical indications. Future studies should explore the relationships between markers of HIV severity and risk of adverse outcomes after THA during the hospital stay and followup. LEVEL OF EVIDENCE Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Kerr E, Middleton A, Churchill D, Walker-Bone K. A case-control study of elective hip surgery among HIV-infected patients: exposure to systemic glucocorticoids significantly increases the risk. HIV Med 2014; 15:182-8. [PMID: 24025108 PMCID: PMC5362063 DOI: 10.1111/hiv.12084] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/06/2013] [Indexed: 11/30/2022]
Abstract
OBJECTIVES This was a cross-sectional study with a nested case-control analysis among a cohort of HIV-infected adults aiming to explore the prevalence of and risk factors for elective hip surgery (total hip arthroplasty and resurfacing). METHODS Cases were identified from the out-patient database of HIV-infected adults attending one tertiary hospital service. For each case, five controls from the same database matched by age, gender and ethnicity were identified. From the case notes, information about demographic factors, HIV factors and risk factors for hip surgery attributable to osteoarthritis or avascular necrosis (body mass index, lipids, alcohol, comorbidities and treatment with oral glucocorticoids) was extracted. RESULTS Among the cohort of 1900 HIV-infected out-patients, 13 cases (12 male) who had undergone hip surgery [0.7%; 95% confidence interval (CI) 0.3-1.1%] were identified, with a median age of 47 years. Eleven of the 13 cases (85%) were Caucasian and seven of the 13 were in stage 3 of HIV infection. Fewer of the cases were in the asymptomatic stage of infection compared with controls [odds ratio (OR) for stage 2 or 3 infection 4.0; 95% CI 0.8-18.5]. Ever having used oral glucocorticoids was highly significantly associated with elective hip surgery (OR 44.6; 95% CI 5.7-347.7). CONCLUSIONS Among this young cohort, the prevalence of elective hip surgery was 0.7%, with the median age at surgery being 47 years. Ever having been exposed to systemic glucocorticoids was highly significantly associated with elective hip surgery, suggesting that the principal mechanism underlying the need for surgery was avascular necrosis. There may be an increased need for elective hip surgery associated with HIV infection.
