Abstract
A man in his 20s with a medical history of syphilis, chlamydia and HIV presented to the emergency department (ED) with 2 months of right hip pain and was found to have advanced avascular necrosis (AVN) of the right femoral head with secondary haemorrhage. The patient lacked the common risk factors of AVN in patients with HIV (PWH): ≥10 years of HIV diagnosis, extended duration on highly active antiretroviral therapy, trauma, corticosteroid use, alcohol abuse, systemic lupus erythematosus, obesity, smoking and dyslipidaemia. Given the extensive destructive changes in the hip joint and muscles, a right hip resection arthroplasty was performed, and the patient recovered well postoperatively. This case presents a learning opportunity for understanding bone pathologies in PWH and offers clinical guidance for the management of HIV-infected patients with a focus on optimising bone health.

AIDS but not asymptomatic HIV is associated with higher 2-10-year implant survivorship following total knee arthroplasty. Knee 2024; 48:76-82. [PMID: 38554491 DOI: 10.1016/j.knee.2024.02.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 02/10/2024] [Accepted: 02/27/2024] [Indexed: 04/01/2024]
Abstract
INTRODUCTION Prior studies have demonstrated HIV does not increase the risk of 2-year complications following TKA; however, the literature is sparse regarding the impact of HIV and AIDS on long-term implant survivorship. The purpose of this study was to compare the 10-year cumulative incidence and risk of revision TKA in patients with and without asymptomatic HIV, and with and without AIDS. METHODS Patients with HIV who underwent elective TKA were identified using a national database and divided into subgroups of asymptomatic HIV (AHIV) and acquired immunodeficiency syndrome (AIDS). These patients with HIV were propensity matched based on age, sex, and Charlson Comorbidity Index (CCI) to a control group of elective TKA patients without HIV in a 1:2 ratio. Patients were also compared to an unmatched control group. RESULTS The 10-year risk for all-cause revision TKA was higher in the HIV group compared to unmatched controls (HR 1.40, 95% CI 1.02-1.93, p = 0.038) but not matched controls (HR 1.13, 95% CI 0.77-1.63, p = 0.594). When compared to both control groups (unmatched; matched), the AIDS group had a higher risk of 10-year all-cause revision (HR 2.74, 95% CI 1.51-4.99, p < 0.001; HR 2.19, 95% CI 1.17-4.11, p = 0.014), dislocation/instability (HR 4.89, 95% CI 1.54-15.51, p = 0.007; HR 3.86, 95% CI 1.12-13.34, p = 0.033), and periprosthetic fracture [PPF] (HR 0.67, 95% CI 0.16-2.74, p = 0.002; HR 3.82, 95% CI 1.08-13.45, p = 0.037). However, patients with AIDS were not at increased risk of PJI or mechanical loosening compared to unmatched controls or matched controls. DISCUSSION This study expands on current literature by following a nationwide cohort of HIV/AIDS patients for 10 years after TKA. Although a diagnosis of asymptomatic HIV was not associated with increased risk of 10-year revision rates following TKA, a diagnosis of AIDS was. Surgeons should ensure patients' serum CD4 level is sufficient, ideally in the normal range of 500-1500 cells per mm3, before undergoing TKA.

J Arthroplasty 2024:S0883-5403(24)00143-8. [PMID: 38452861 DOI: 10.1016/j.arth.2024.02.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 02/04/2024] [Accepted: 02/11/2024] [Indexed: 03/09/2024] Open
Abstract
BACKGROUND Total hip arthroplasty (THA) has become a common intervention for human immunodeficiency virus (HIV)-positive patients who have osteonecrosis of the femoral head. This paper provides a systematic review to assess survivorships, patient-reported outcomes (PROMs), infection rates, other complications, and immune competence for patients who had THAs who did and did not have HIV. METHODS A comprehensive and systematic review of published studies investigating the outcomes of THA in HIV-positive patients (osteonecrosis and non-osteonecrosis patients) was performed adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A total of 10 studies with 9,534 HIV-positive patients fulfilled the inclusion and exclusion criteria. Manuscript quality was assessed on 2 scales: the Coleman Methodology Score and the level of evidence derived from Center for Evidence-Based Medicine criteria. Data were extracted from studies in the 5 key areas of interest: survivorships, PROMs, infection rates, complications, and clusters of differentiation-4 (CD4+) counts and viral loads. RESULTS Implant survivorship was between 95% and 100%. Postoperative Harris Hip Scores were significantly improved from preoperative values in HIV-positive patients. Postoperative PROMs and infections did not appear to be different between HIV-positive and HIV-negative patients. Many of the cohort studies demonstrate comparable complication rates to matched controls. Where described (7 reports), mean CD4+ counts ranged from 425 to 646 cells/mm3, with low viral loads (3 reports) and variations not found to influence outcomes. CONCLUSIONS THA is an effective treatment for HIV-positive patients, many of whom suffer from osteonecrosis of the femoral head. The results demonstrate excellent implant survivorship, improved quality of life, and a low risk of infections and complications.

Abstract
Background With the increasing life expectancy of people living with HIV (PLWH) following antiretroviral therapy (ART), there is a growing prevalence of chronic diseases such as osteonecrosis of the femoral head (ONFH). Compared with the more accessible blood, the viral infection profile in bone marrow and necrotic femoral heads in PLWH remains inadequately characterized. Methods Femoral head and bone marrow were collected from 15 PLWH undergoing total hip arthroplasty. For each femoral head, samples were obtained from the subchondral, necrotic, sclerotic, and normal areas. HIV DNA and HIV RNA assays were employed to evaluate disparities in viral load and reservoir between bone marrow and blood, as well as to quantify viral infection in distinct regions of the necrotic femoral head. Results Blood HIV RNA dropped below detectable levels in 8 patients (below 20 copies/mL). The median of bone marrow HIV RNA was 255.89 copies/mL. HIV DNA in blood and bone marrow was 296.35 and 454.31 copies/106 cells. HIV DNA in necrotic area was about half that in sclerotic area, HIV RNA was about twice that in normal area, the difference was statistically significant. Conclusion Despite using ART, there is still substantial active HIV and a potential reservoir in the bone marrow. Viral transcription was most active in the necrotic area of the femoral head, which may indicate that HIV itself is directly involved in ONFH.

Abstract
Background The incidence of osteonecrosis of the femoral head (ONFH) in people with human immunodeficiency virus (HIV) is 10-100 times higher than that in the general population. However, the specific bone microstructure and extent of damage within the femoral head in PWH are still unclear. Methods Femoral head samples were obtained by total hip arthroplasty, micro-computed tomography (micro-CT) was employed to investigate the microstructure of trabecular bone across 4 representative regions within necrotic femoral heads, and quantitative analysis was performed. Results On general observation, different degrees of degenerative cartilage, fibrocartilage, hyperplastic bone, and exposed bone were presented alternately, with a "map-like" appearance. On micro-CT, compared with the normal and necrotic areas, the bone volume/tissue volume and bone mineral density of the sclerotic areas were significantly increased, the number of trabeculae was significantly increased, and the gap was smaller (P < .05). There was no significant difference in trabecular thickness among the groups (P < .05). Conclusions The systemic immune syndrome caused by HIV itself may interfere with the normal metabolism of bone, including osteoblasts and osteoclasts, and thus participate in HIV-related ONFH.

Analysis of the efficacy of drilling decompression autologous bone marrow and allogeneic bone grafting in the treatment of HIV-positive patients with early osteonecrosis of the femoral head. BMC Musculoskelet Disord 2023; 24:902. [PMID: 37990216 PMCID: PMC10661564 DOI: 10.1186/s12891-023-07039-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Accepted: 11/12/2023] [Indexed: 11/23/2023] Open
Abstract
OBJECTIVE To investigate the efficacy of treating patients with HIV-positive osteonecrosis of the femoral head using drilled decompression autologous bone marrow and allogeneic bone grafting. METHODS 40 patients (44 hips) with early osteonecrosis of the femoral head treated by drilling decompression autologous bone marrow and allogeneic bone grafting since October 2015 were retrospectively analyzed, among which 20 patients (24 hips) were HIV-positive patients with early osteonecrosis of the femoral head, 16 males and 4 females, age 22-43 years, average 39.6 ± 10.18 years, and 20 patients (20 hips) in the same period HIV-negative early osteonecrosis of the femoral head patients, 13 males and 7 females, aged 48-78 years, mean 63.50 ± 7.94 years were negative controls. General information including ARCO stage, Harris score, VAS score, hematological indexes including CD4+ T lymphocyte count, and HIV viral load was recorded for all patients before surgery. All patients were operated on by drilling and decompression of the necrotic area, harvesting autologous iliac bone marrow with allogeneic bone, and bone grafting through the decompression channel. The patients were followed up regularly at 6, 12, and 24 months after surgery and annually thereafter, and the repair of the necrotic femoral head was observed by reviewing the frontal and lateral X-ray, CT or MRI of the hip joint, and the complications and functional recovery of the hip joint was counted and compared between the two groups. RESULTS All patients were followed up, and the ARCO stages in the HIV-positive group were stage I 2 hips, stage IIA 6 hips, stage IIB 8 hips, stage IIC 6 hips, and stage III 2 hips, with a follow-up time of 12 to 60 months and a mean of 24.6 months. In the negative control group, there were 3 hips in ARCO stage I, 7 hips in stage IIA, 5 hips in stage IIB, 3 hips in stage IIC, and 2 hips in stage III, and the follow-up time ranged from 13 to 62 months, with an average of 24.8 months. The Harris score and VAS score of the hip in both groups improved significantly at 6 months postoperatively compared with those before surgery (P < 0.001). The difference between the Harris score of the hip in the positive group at 24 months postoperatively compared with that at 6 months postoperatively was statistically significant, but the VAS score at 24 months postoperatively compared with that at 6 months postoperatively was not statistically significant. In the negative group, there was no statistically significant difference in the Harris score and VAS score of the hip at 24 months postoperatively compared with those at 6 months postoperatively. In the positive group, there was a trend of continuous increase in hip BMD from the beginning of the postoperative period (P < 0.001). There was no statistically significant difference between the negative group and the positive group at the 24 months postoperatively follow-up except for the Harris score, which was statistically significant (P < 0.001), and the VAS score, which was statistically insignificant. At the 24 months postoperatively follow-up, patients in both groups had good recovery of hip function, and no complications such as vascular and nerve injury and fracture occurred during the perioperative period and follow-up period, and no complications related to incisional infection and pulmonary infection occurred during hospitalization. CONCLUSION The treatment of early HIV-positive osteonecrosis of the femoral head patients with autologous bone marrow and allogeneic bone grafting by drilling and decompression to remove the tissue in the necrotic area of the femoral head can effectively stop the process of osteonecrosis of the femoral head and promoting femoral head repair in HIV-positive patients is a safe and effective method for treating HIV-positive patients with early osteonecrosis of the femoral head, and can effectively delay or postpone total hip replacement in patients.

Abstract
Background Studies have reported that osteonecrosis of the femoral head (ONFH) is more prevalent in patients with human immunodeficiency virus (HIV). Total hip arthroplasty (THA) is considered reasonable management of ONFH. However, only scarce data exist on the outcomes of THA for HIV-infected patients in South Korea. The purpose of this study was to evaluate the midterm results of HIV-positive patients who underwent THA for ONFH. Methods We performed a retrospective review of HIV-infected patients with ONFH who underwent THA in our institution from 2005 to 2021. Twenty-two hips in 15 patients underwent THAs with cementless implants. The clinical and radiographic evaluation was performed at each follow-up, and any complication was recorded. Results The mean follow-up period was 5.2 years (range, 1.0-16.0 years). The mean age of the HIV infected patients with osteonecrosis at the time of surgery was 44.7 ± 11.6 years. ONFH occurred 9.8 ± 3.7 years after the initial diagnosis of HIV infection. The average modified Harris hip score improved from 58.3 ± 14.8 to 95.2 ± 11.3 at the latest follow-up. Surgical complications such as infection, nerve injury, or dislocation were not present. The radiographic evidence of stable fixation by bone ingrowth without migration was seen in all implants. Conclusions Our data suggest that THA is a safe and valid option of treatment for ONFH in well-controlled HIV-infected patients in Korea. Further large-scale nationwide studies are warranted.

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
The incidence of human immunodeficiency virus (HIV)-infected cases that need total joint replacement (TJR) is generally rising. On the other hand, modern management of HIV-infected cases has enabled them to achieve longevity while increasing the need for arthroplasty procedures due to the augmented dege-nerative joint disease and fragility fractures, and the risk of osteonecrosis. Although initial investigations on joint replacement in HIV-infected cases showed a high risk of complications, the recent ones reported acceptable outcomes. It is a matter of debate whether HIV-infected cases are at advanced risk for adverse TJR consequences; however, the weak immune profile has been associated with an increased probability of complications. Likewise, surgeons and physicians should be aware of the complication rate after TJR in HIV-infected cases and include an honest discussion of the probable unwelcoming complication with their patients contemplating TJR. Therefore, a fundamental review and understanding of the interaction of HIV and arthroplasty are critical.

Abstract
Background Nontraumatic osteonecrosis of the femoral head (ONFH) can be corticosteroid-induced, alcohol-induced, and idiopathic ONFH (IONFH). Although corticosteroid- and alcohol-induced ONFH has been investigated extensively regarding its relationship with blood lipids and coagulation factor levels. However, the effect of blood lipid metabolism and coagulation function on IONFH has rarely been studied. Therefore, this study aimed to analyse the relationship of IONFH with blood lipid and coagulation indicators. Methods Total 680 patients diagnosed with IONFH in our institution during January 2011-June 2019 who met the inclusion criteria composed the case group; 613 healthy persons who underwent physical examination at our institution during the same period composed the control group. Propensity scores were used for baseline feature matching, and two matching groups each with 450 patients were established. After the matching, blood lipid and coagulation factor levels of both groups were comparatively analysed. Results The case group showed significantly higher total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL) levels, low-density/high-density lipoprotein (LDL/HDL) ratio, and apolipoprotein B (Apo-B) levels than the control group (p < 0.05). Conversely, the HDL and apolipoprotein A (Apo-AI) levels in the case group were significantly lower than those in the control group (p < 0.05). Regarding coagulation indicators, the activated partial thromboplastin time and prothrombin time were lower in the case group than in the control group; however, the differences were insignificant (p > 0.05). Furthermore, fibrinogen (FIB) levels and thrombin time (TT) in the case group were higher than those in the control group. There were significant differences between the two groups only in terms of FIB levels (p < 0.05), while TT was not significantly different (p > 0.05). Conclusions IONFH has strong associations with blood lipid metabolism and coagulation function, which provide an avenue for exploring the mechanism of IONFH.

Abstract
BACKGROUND Femoral head osteonecrosis (FHON) is a well-recognised complication in patients with human immunodeficiency virus (HIV) infection. Total hip arthroplasty (THA) is a reliable solution to FHON and has provided functional improvement and pain relief in these patients. Higher complication rates, in particular infections, have been reported in the series of THAs done in the HIV-positive patients. The purpose of this study was to evaluate the complication rate of THA for FHON in HIV-positive patients managed with the highly active antiretroviral therapy (HAART) protocols. METHODS A retrospective review was performed of HIV-positive patients with FHON who underwent THAs over a 10-year period at a single institution. RESULTS A total of 56 THAs (44 patients) met the inclusion criteria. The mean age at the time of THAs was 47 (range 34-60) years. Of the 44 patients, 39 (88.6%) were males. The mean follow-up was 6.6 (range 2.0-11.3) years. The overall complication rate was 12.5%, with 2 (3.6%) cases of deep periprosthetic infections. CONCLUSIONS HIV-positive patients with FHON undergoing THAs do have a considerable complication rate (12.5%). The deep periprosthetic infection rate (3.6%) in these patients, however, has decreased with contemporary disease modification protocols.

Abstract
Background Patients with HIV have a higher prevalence of thrombocytopenia than those without HIV infection, increasing their risk of substantial perioperative blood loss (PBL) during total hip arthroplasty (THA). This study aimed to evaluate PBL risk factors in HIV-infected patients undergoing THA. Methods Eighteen HIV+ patients (21 hip joints) and 33 HIV− patients (36 joints) undergoing THA were enrolled in this study. PBL was calculated using the Gross equation, which comprises total blood loss (TBL), dominant blood loss (DBL), and hidden blood loss (HBL). Risk factors for post-THA PBL in both patient populations was evaluated using multivariable linear regression. Results At baseline, the HIV+ patients were younger, more likely to be male and to have elevated hemoglobin and albumin levels, and lower erythrocyte sedimentation rates than HIV− patients. There were no differences in the T-lymphocyte subsets or coagulation function between the two groups. Age and albumin level were identified as potential HBL risk factors after THA, and albumin level was associated with higher TBL. The unadjusted linear regression analysis showed that the HBL and TBL were significantly higher in HIV+ patients than in HIV− patients. However, after adjusting for other factors, no differences in DBL, HBL, or TBL were observed between HIV− and HIV+ patients. Conclusion PBL was similar in both groups undergoing THA, regardless of their HIV-infection status. THA surgery is a safe and effective procedure in HIV+ patients.

Abstract
BACKGROUND Osteonecrosis of the femoral head (ONFH) is a frequent and refractory disease whose pathogenesis has not yet been elucidated. Infection and other factors that reduce the local blood supply can lead to bone necrosis.
AIM To aim of this study was to assess the relationship of ONFH with bone infection by use of metagenomic sequencing.
METHODS Twelve patients with idiopathic ONFH and 12 comparable controls who were undergoing hip arthroplasty were followed up in parallel. Necrotic femoral head specimens were collected for bacterial and fungal cultures using standard methods. Bone specimens were subjected to preliminary processing, and metagenomics sequencing of microorganisms was performed. A one-way analysis of variance was used to compare bacterial species in the two groups.
RESULTS Bacterial and fungal cultures exhibited no evidence of microbial growth in all isolated necrotic femoral head tissues. We thus performed metagenomic sequencing and classified the species as suspected pathogens or suspected background microorganisms based on known bacterial pathogenicity. There was no evidence of viruses, fungi, parasites, M. tuberculosis complex, or mycoplasma/chlamydia. There were also no significant differences in suspected pathogens or suspected background microorganisms (P > 0.05).
CONCLUSION Although we found no pathogens specific for ONFH in necrotic femoral head tissue, our research provides a foundation for future research on the metagenomics of bone pathogens.

Abstract
Background Human immunodeficiency virus-infected patients are 100 times more likely to develop aseptic osteonecrosis compared with the general population. While 90% of cases concern the femoral head, the involvement of humeral bone remains rare. Case presentation We report a case of aseptic osteonecrosis of the left humeral head complicating antiretroviral therapy in a female, 46-year-old, Bissau-Guinean human immunodeficiency virus-infected patient received in a context of progressive pain in the left shoulder followed by limitation of articular movements. Standard x-ray of the shoulder allowed us to make the diagnosis by showing a typical image of osteonecrosis. The treatment was medical combined with physiotherapy. Conclusions Aseptic osteonecrosis should be systematically looked for in human immunodeficiency virus patients on antiretroviral treatment. In addition to femoral head aseptic necrosis, the involvement of the humeral bone should also be considered.

Abstract
Avascular necrosis of the femoral (AVN) head is a disabling disease that affects function, mobility, and quality of life in the young adult. Its pathology involves blood circulation disruption of the femoral head and subchondral infarction. This leads to cartilage thinning, femoral head depression, and cartilage breakage, which results in hip osteoarthritis. In the past decade the prevalence of intraarticular pathology has been almost 95%, this revealed with hip arthroscopy (HA). HA and core decompression (CD) of the femoral head can be used effectively and concomitantly to treat AVN with excellent results, HA allows for excellent visualization of the hip joint cartilage, allowing treatment of femoroacetabular impingement syndrome (FAIS) and intra-articular pathology. Our technique demonstrates that retrograde core decompression with allograft and mixed bone matrix is an excellent choice of treatment in the early stages of AVN/ONFH. The femoral head-specific aiming guide is very reliable, is simple to use arthroscopically if placed in the posterolateral portal of the hip, and offers exact pin placement at the necrotic site, as well as less operative time and less radiation to the patient and surgical team.

HIV-Positive Patients Are at Increased Risk of Venous Thromboembolism After Total Joint Replacement. J Am Acad Orthop Surg 2021; 29:479-485.

Abstract
BACKGROUND Antiretroviral therapy has improved the life expectancy of HIV patients, leading to an increase in total joint replacement for age-related osteoarthritis. HIV patients are inherently hypercoagulable at baseline. The goal of our study was to compare the incidence of venous thromboembolism (VTE) in HIV patients with HIV-negative controls after total joint replacement. METHODS A multicenter, retrospective cohort study of 110 HIV patients (85 hips and 25 knees) and 240 HIV-negative controls (180 hips and 85 knees) between 2000 and 2018. Prophylactic anticoagulation was used in 98% of patients postoperatively-low-molecular weight heparin (73%), warfarin (19%), aspirin (6%), and clopidogrel (1%). RESULTS The VTE rate was 3.6% in the HIV-positive group (2.5% total hip arthroplasty [THA] and 8.0% total knee arthroplasty [TKA]) and 0.4% in the control group (0% THA and 1.7% TKA). VTEs occurred at the median (interquartile range) time of 40 days (1 to 52) post-op in the HIV group and 3 days post-op in the one control. Multivariable logistic regression adjusting for sex, smoking, history of VTE, and joint replaced identified HIV as an independent predictor of VTE (odds ratio 10.9, 95% confidence interval 1.1 to 114.0, P = 0.046). All patients with VTE were treated with warfarin (5 to 9 months); two cases were complicated by hemarthrosis and excessive bleeding at the insulin injection site. CONCLUSION We observed increased rates of symptomatic VTE in HIV patients after THA (2.5%) and TKA (8%) compared with HIV-negative control patients (0% and 1.7%, respectively). HIV positivity was identified as an independent predictor of perioperative VTE. Our data suggests that HIV patients may be at higher risk for post-op VTE than HIV-negative patients. Surgeons may want to consider the use of more potent anticoagulation (ie, warfarin or novel anticoagulants) for a longer duration in HIV-positive patients. However, further studies are necessary to form evidence-based guidelines regarding this practice. LEVEL OF EVIDENCE Level III, prognostic.

Abstract
BACKGROUND Patients with HIV are more likely to require a total hip arthroplasty (THA) because of an increase in life expectancy and complications with HIV. The purpose of this study is to describe the mid-term outcomes of THA in HIV-positive patients and risk factors for postoperative infections and poor outcomes. METHODS This is a single-center retrospective review of nonhemophiliac HIV-positive patients who underwent THA. We reviewed the short- and mid-term readmission and complication rates. RESULTS Eighty-seven patients underwent 102 THAs. The average age was 58 years (24-73 years). The average body mass index was 31.6 (18-55). The average CD4+ count was 569 cells per cubic millimeter (mm3) (51-1480), and the mean viral load was <40 copies/mL (undetectable-380 000). The mean follow-up time was 6.7 years (24 months- 8.3 years). Four patients had postoperative complications within 30 days. Seven patients had postoperative complications after 30 days; 5 of which had septic loosening of implants and had either not been initiated on or were noncompliant with their highly active antiretroviral therapy. The average postoperative Harris Hip Score was 81 (41-100) and Oxford Hip Score was 43.43 (34-48). There was no correlation the between CD4+ count and viral load with complications. CONCLUSION Low rate of complications and revision is achievable in the HIV-positive, nonhemophilic arthroplasty population contrary to published literature. An important factor ensuring good long-term outcomes in HIV-positive patients undergoing THA was the initiation of highly active antiretroviral therapy before the procedure and ensuring patient compliance with therapy after joint arthroplasty.

Abstract
Background Osteonecrosis of the femoral head (ONFH) is a disabling condition that often necessitates total hip arthroplasty (THA). Although ONFH occurs more frequently among patients with human immunodeficiency virus (HIV) than among the general population, there is little epidemiological information regarding ONFH in Korean patients with HIV. In the present study, we aimed to investigate the incidence and clinical features of ONFH among Korean patients with HIV. Materials and Methods In this retrospective study, we reviewed the medical records of 1,250 Korean patients with HIV treated from January 1990 to December 2019. A standardised data collection sheet was used to obtain clinical information. Imaging data were analysed by a radiologist in accordance with the 2019 revised version of the Association Research Circulation Osseous (ARCO) staging system for ONFH. Results Among the 1,250 included patients, 13 patients (1.04%; 3 women, 10 men) were diagnosed with ONFH. The overall incidence of ONFH was 1.29 per 1,000 person-years (PYs) (95% confidence interval [CI]: 0.7 – 2.4 per 1,000 PYs). Median age among the 13 patients with ONFH was 47 years (interquartile range [IQR]: 41 – 57 years). The median duration since HIV diagnosis was 4.8 years (IQR: 2.3 – 10.1 years). The median CD4 cell count at the time of ONFH diagnosis was 381 cells/ mm3 (IQR: 161 – 551 cells/mm3). At the initial diagnosis of ONFH, 83.3% of patients exhibited bilateral involvement. ARCO stage 3 or 4 osteonecrosis was observed in 83% of patients. Among 22 hips, stage 1 ONFH was noted in 2 (9.1%), stage 2 ONFH was noted in 7 (31.8%), stage 3 ONFH was noted in 9 (40.9%), and stage 4 ONFH was noted in 4 (18.2%). THA was eventually performed in 84.6% of patients. Five (38.5%) patients had a history of steroid use, 4 (30.8%) patients had a history of alcohol abuse and 10 (76.9%) were smokers. Eight (61.5%) patients had a history of acquired immune deficiency syndrome-defining illness, including 7 with tuberculosis and 1 with pneumocystis pneumonia. Nine patients (69.2%) had a nadir CD4 cell count <200/µL, and 3 (23.1%) had a history of bone fracture. Overall, 84% of patients were exposed to antiretroviral therapy, while 54% had taken protease inhibitors for more than 1 year. Conclusion Considering that relatively high incidence of ONFH in patients with HIV, a high index of suspicion for those with risk factors and those with groin or hip pain for is required in HIV-infected patients.

Abstract
BACKGROUND Joint preservation is more effective in early-stage osteonecrosis of the femoral head (ONFH); thus, prompt diagnosis when the femoral head is still salvageable is important. We report a 20-year retrospective study that summarizes age at presentation, etiology, and Association Research Circulation Osseous stage at diagnosis. METHODS Our database was reviewed to identify patients younger than 65 years of age who were diagnosed with atraumatic ONFH between 1998 and 2018. Demographic characteristics of patients were evaluated and categorized into different subgroups. RESULTS Four hundred thirteen patients were identified. At initial presentation, 23% were diagnosed with early-stage ONFH, while 77% were diagnosed with late-stage ONFH. Forty-nine percent had a history of corticosteroid use, of which 13% were diagnosed with hematologic malignancy and 8% were diagnosed with lupus. Ethanol abuse, idiopathic, sickle cell disease, and human immunodeficiency virus were present in 11%, 30%, 3%, and 3%, respectively. The mean age of patients with corticosteroid use (40 ± 14 years) was significantly younger than ethanol use (46 ± 11 years, P = .014) and idiopathic causes (48 ± 11 years, P < .001), but significantly older than sickle cell disease (32 ± 11 years, P = .031). There was no difference in the age of presentation for early-stage and late-stage ONFH by etiology. CONCLUSION Nearly 80% of the patients presented with late-stage ONFH. Hence, we have a narrow window of opportunity for hip preservation surgery before femoral head collapse. A multidisciplinary approach to improve screening awareness for early detection by focusing on the etiologic identification and patient education might reduce the incidence of hip arthroplasty in young patients.

Abstract
We report a case of avascular necrosis (AVN), hypercalcemia, and iatrogenic Cushing’s syndrome in an HIV-positive patient taking inhaled (ICS) and nasal corticosteroids fluticasone and ritonavir. A 45-year-old HIV-infected African-American woman was seen for initial evaluation for multinodular goiter in December 2015. Relevant medications were ritonavir, raltegravir, darunavir, fluticasone propionate HFA, and nasal fluticasone propionate. Physical examination revealed classical cushingoid appearance but laboratory testing showed abnormal adrenocorticotropic hormone (ACTH) stimulation test. A diagnosis of iatrogenic Cushing’s syndrome due to inhibition of fluticasone metabolism from protease inhibitor (PI) therapy with secondary adrenal suppression was made. Fluticasone nasal spray and HFA were discontinued and hydrocortisone replacement dose was initiated. The patient’s Cushing’s related symptoms improved over several months. Follow-up evaluation showed non-parathyroid hormone-mediated hypercalcemia. A detailed laboratory evaluation looking for the etiology for hypercalcemia was unremarkable except for an elevated urine N-telopeptide/creatinine ratio. Meanwhile, the patient developed a new symptom of hip pain. MRI of both hips showed bilateral AVN. Sickle cell screen was negative and a right hip replacement was completed in May 2017. Since this is the fourth case report of AVN from iatrogenic Cushing’s syndrome in an HIV-infected patient taking a PI and ICS concomitantly, there is more likely a causal relationship and not simply a coincidental finding. Extreme caution should be used when considering any ICS therapy in combination with PIs in HIV-infected patients.

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
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
We present a young man with a background Human Immunodeficiency virus (HIV) who presented with bilateral knee pain and reduced mobility. Subsequent imaging of the knees demonstrated florid osteonecrosis (ON), which was managed conservatively. ON is seen more commonly in HIV patients than the general population, however the underlying mechanism for this association is remains unclear. An awareness of this disease is imperative to appropriately identify and manage such patients.

Abstract
Despite the development of newer preventative measures, the rate of infection continues to be approximately 1% for patients undergoing total joint arthroplasty (TJA). The extent of the infection can range from a mild superficial infection to a more serious periprosthetic joint infection (PJI). PJIs not only play a significant role in the clinical well-being of the TJA patient population, but also have substantial economic implications on the health care system. Several approaches are currently being used to mitigate the risk of PJI after TJA. The variety of prophylactic measures to prevent infection after TJA must be thoroughly discussed and evaluated.

Abstract
With the advent of highly active antiretroviral therapy (HAART), total joint arthroplasty has become a safe and effective procedure for patients infected with the human immunodeficiency virus (HIV). A correlation between a low CD4+ count (<200 cells/mm3) and major postoperative complications such as deep joint infection has been postulated, although high-level studies are not available in the literature. As most studies have not demonstrated an increase in the incidence of deep-vein thrombosis in patients with HIV/AIDS (acquired immunodeficiency syndrome), our recommendation is to use the standard prophylaxis that is followed by the operating surgeon.

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
Objective To examine the presence of HIV in bone tissue of people living with HIV (PLWHIV) with osteonecrosis of femoral head and describe clinical and anatomopathological findings. Design This is a case series which included 44 PLWHIV with osteonecrosis of femoral head who underwent total hip arthroplasty. Methods Clinical data were obtained through analysis of the patients’ medical records. Bone tissue obtained during total hip arthroplasty was retrieved and sent for conventional and immunohistochemical analysis. Monoclonal antibodies were used to mark the p24 (HIV), CD31 (vascular endothelial cells), CD68 (macrophages), and D240 (cells of the lymphatic endothelium) antigens. Results Dyslipidemia was found in 48% of the patients and lipodystrophy in 31%. Histological analysis showed similar characteristics for the entire sample. Degeneration of joint cartilage was visualized with the presence of fissures and fibrillations, as well as subchondral sclerosis and necrosis of the subchondral cancellous bone tissue. Lymphoplasmocytic inflammatory reaction was observed, with the presence of macrophages containing a foamy, vacuolated cytoplasm, as well as the presence of ceroid pigment and occasional granulation tissue. The reaction with the monoclonal anti-p24 antibody was negative in the samples from all 44 PLWHIV undergoing hip arthroplasty. Reactions with the anti-CD31 and anti-D240 antibodies were negative. Staining with CD68 antibody confirmed that the cells visualized with foamy, vacuolated cytoplasm were macrophages. Conclusion p24 HIV antigen was not detected in the bone tissue of PLWHIV and osteonecrosis. The most frequent anatomopathological findings were extensive necrosis of bone tissue, large vacuoles filled with fat cells, inflammatory lymphoplasmocytic reaction with macrophages containing vacuolated cytoplasm, and the presence of ceroid pigment.

Abstract
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
With antiretroviral therapy, patients who are human immunodeficiency virus (HIV)-positive are increasingly becoming candidates for total hip arthroplasty (THA) and total knee arthroplasty (TKA). Prior reports focus on perioperative complications, but longer-term outcomes remain unclear. The authors specifically analyzed clinical outcomes, perioperative complications, and survivorship free of periprosthetic joint infection (PJI) of THAs and TKAs in HIV-positive patients who had extended follow-up. A total of 21 HIV-positive patients who underwent 29 primary arthroplasties (14 THAs, 15 TKAs) from 1992 to 2012 were retrospectively reviewed. Mean age was 43 years and mean follow-up was 8 years. Mean perioperative CD4 cell count was 450 cells/mL; only 2 patients had perioperative CD4 cell counts less than 200 cells/mL. At mid-term follow-up, THAs and TKAs were reliable in improving function (mean postoperative Harris Hip Score: 87, P<.01; mean postoperative Knee Society Score: 83, P<.01). The rate of perioperative complications was high (17%). Patients with both hemophilia and HIV were at particular risk for complications at 33% (P=.04). Survivorship free of deep PJI was 100% in THAs at 10 years and 93% in TKAs at 10 years. Only 1 (7%) patient (1 TKA), who had a perioperative CD4 cell count of less than 200 cells/mL, was revised for deep PJI. In HIV-positive patients, both THAs and TKAs are reliable in alleviating pain and improving clinical function at mid-term follow-up. However, HIV-positive patients are at substantial risk of perioperative complications, especially with comorbid hemophilia. With antiretroviral therapy and maintained CD4 cell counts above 200 cells/mL, survivorship free of deep PJI approaches 100%. [Orthopedics. 2017; 40(4):e699-e702.].

Abstract
BACKGROUND AND OBJECTIVE The exploration for the etiology of osteonecrosis of the femoral head (ONFH) has got some promising findings, but the morbidity of ONFH is still not under control. The C3435T polymorphism of ATP-binding cassette subfamily B member 1 (ABCB1) gene has been reported to possess significant influence on ONFH onset, but relevant outcomes remain conflicting rather than conclusive. Therefore, a meta-analysis was useful to pool these results together for a more reliable conclusion. METHODS The association of ABCB1 C3435T polymorphism with ONFH susceptibility was estimated through calculated odds ratios (ORs) with their 95% confidence intervals (95% CIs). The Q-test was applied for detecting inter-study heterogeneity, whereas sensitivity analysis for identifying any study owning substantial influence on pooled results. Begg's funnel plot and Egger's test were employed to examine publication bias across included studies. RESULTS ABCB1 C3435T polymorphism significantly decreased the risk of ONFH under TT vs CC (OR = 0.26, 95% CI = 0.13-0.50), TT+CT vs CC (OR = 0.72, 95% CI = 0.52-0.99), TT vs CC+CT (OR = 0.28, 95% CI = 0.15-0.52), and T vs C (OR = 0.64, 95% CI = 0.50-0.81) contrasts. CONCLUSION The variant C3435T in the ABCB1 gene may offer protection against the attack of ONFH, and more studies with larger sample sizes should be conducted to certify this issue.

Liu F, Wang W, Yang L, Wang B, Wang J, Chai W, Zhao D. An epidemiological study of etiology and clinical characteristics in patients with nontraumatic osteonecrosis of the femoral head. JOURNAL OF RESEARCH IN MEDICAL SCIENCES 2017; 22:15. [PMID: 28458706 PMCID: PMC5367210 DOI: 10.4103/1735-1995.200273] [Citation(s) in RCA: 43] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/29/2016] [Revised: 10/15/2016] [Accepted: 11/10/2016] [Indexed: 02/03/2023]
Abstract
Background: Osteonecrosis of the femoral head (ONFH) is a common disease with high disability rate. However, a few studies investigate the etiology and clinical characteristics of nontraumatic ONFH patients in China. Therefore, we conducted this cross-sectional study. Materials and Methods: Totally, information of 7268 nontraumatic ONFH patients treated between August 2005 and August 2015 was extracted from the medical records. The extracted information included the age, gender, diagnostic criteria, cause of nontraumatic ONFH, types of steroid use, and types of alcohol. Results: Among these included patients, there were 5126 (70.5%) male patients with average age of 44.5 years and 2142 (29.5%) female patients with average age of 47.6 years (P = 0.54). The number of steroid-, alcohol-, steroid/alcohol-, and idiopathic-induced nontraumatic ONFH men patients was 1684, 2310, 364, and 768, respectively, and nontraumatic ONFH women patients was 1058, 482, 140, and 462, respectively. Meanwhile, we found that both the levels of triglycerides (P = 0.03) and low-density lipoprotein (P = 0.02) were significantly changed in the idiopathic-induced nontraumatic ONFH patients. Conclusion: These results indicated the earlier onset of nontraumatic ONFH in male patients than in female patients, different main etiology for male (alcohol consumption) and female (steroid use) patients, and close relationship between the lipid metabolism and idiopathic-induced nontraumatic ONFH. Our findings could be helpful for researchers to investigate the pathogenesis of ONFH and aid the clinicians in the early prevention and diagnosis of nontraumatic ONFH.

Clin Orthop Relat Res 2017; 475:465-471. [PMID: 27743304 PMCID: PMC5213948 DOI: 10.1007/s11999-016-5122-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2016] [Accepted: 10/07/2016] [Indexed: 01/31/2023]
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. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
About 150,000 people are HIV-positive in France, and the number of new cases is estimated at 7000-8000 per year, with no tendency to diminish over time. Admissions of HIV-positive patients have been decreasing, in contrast, since 2008, reflecting the dramatic improvements in quality of life and survival provided by triple antiretroviral regimens. HIV infection is now a chronic disease that exposes patients to the virus and antiretroviral drugs for many years. One consequence has been the emergence of new health conditions in HIV-positive patients, such as tumors, cardiovascular disease, and osteoarticular complications. These epidemiological and clinical changes have made it necessary for rheumatologists to learn about the osteoarticular abnormalities associated with the HIV, which they are likely to encounter at some point during their everyday practice. Osteoporosis is one such abnormality, and this review article starts with a discussion of the literature on this topic. Bone loss is common, chiefly in males. Multiple factors are involved. Studies have demonstrated an increase in the fracture risk and, consequently, recommendations about the screening and treatment of osteoporosis have been issued. The focus of this review article then turns to the other rheumatic manifestations seen in HIV-positive patients, including osteomalacia, avascular necrosis, and inflammatory joint disease. Osteoarticular pain is frequently reported by HIV-positive patients. Identifying the cause is essential to determine the best treatment strategy. Interestingly, immunosuppressant drugs, and even biotherapies, have shown a good safety profile in these immunodeficient patients.

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
Background: Studies have reported that patients with human immunodeficiency virus (HIV) have a high incidence of osteonecrosis of the femoral head (ONFH). Total hip arthroplasty (THA) is an effective management of ONFH. However, little data exist regarding the use of THA for the HIV patients with ONFH in China. This study reviewed the outcomes of HIV-positive patients who underwent THA for ONFH, compared with HIV-negative individuals. Methods: The patients who underwent THA for ONFH from September 2012 to September 2014 in Beijing Ditan Hospital, Capital Medical University were retrospectively studied. Twenty-eight HIV-positive patients and 35 HIV-negative patients underwent 48 THAs and 45 THAs with cementless components, respectively. Medical records and follow-up data were reviewed. Harris Hip Score (HHS) was applied to evaluate the pain and function of the hips before and after THA. Complications such as wound healing, surgical site infection, deep venous thrombosis, pulmonary embolism, sepsis, mortality, and complications from the prosthesis were reviewed. The operation time, blood loss, and hospital stay were compared between the two groups. Results: The mean follow-up period was 19.5 ± 5.8 months (ranging from 6 to 30 months). The mean age of the HIV-positive patients with osteonecrosis at the time of surgery was 35 years old, which was significantly lower than that of the HIV-negative group (42 years old) (P < 0.05). The HIV-positive patients underwent surgery a mean of 2.5 years after their original symptoms, which was significantly shorter than the HIV-negatives’ (mean 4 years) (P < 0.05). Among HIV-positive patients, the prevalence of being male and rate of bilateral procedures were significantly higher than those in the HIV-negative group (P < 0.05). The operation time in HIV-positive patients was significantly longer than that in HIV-negative patients (P < 0.05). There were no significant differences in blood loss or hospital stay between the two groups (P > 0.05). The HHSs of two groups significantly improved after THAs (P < 0.05), without significant difference between two groups. No wound complication, sepsis, mortality, prosthesis complication, and occupational exposure occurred, except for two cases of heterotopic ossification and one case of humeral head necrosis. Conclusions: ONFH is more likely to occur bilaterally in younger HIV-positive males. The development of osteonecrosis seems faster in HIV-positive patients than in HIV-negative patients. This should be cautionary for asymptomatic HIV-positive patients with low viral RNA level and in the primary HIV stage. Despite longer operation times in the HIV-positive patients than in the HIV-negative patients, THA is still a safe and efficient approach to treat ONFH in HIV-positive patients. The incidence of complications is much lower than previously reported. However, the long-term follow-up is needed.

Abstract
Objectives: To evaluate the initial functional results and early complication rate of ceramic-ceramic total hip replacements among patients living with HIV who presented osteonecrosis of the femoral head. Method: Twelve HIV–positive patients with a diagnosis of osteonecrosis of the incongruent femoral head were evaluated using clinical and laboratory criteria and the WOMAC functional scale before and after treatment with joint replacement. Results: We observed that 83.3% of the subjects were taking protease inhibitors, 75% had dyslipidemia and 66.6% had lipodystrophy syndrome. The improvement over the evolution of the WOMAC score was statistically significant at six and twelve months after the operation, in comparison with the preoperative score. We did not observe complications secondary to this procedure. Conclusion: Total hip arthroplasty with a ceramic-ceramic implant for treating avascular necrosis of the hip is an appropriate surgical option for this portion of the population. It provides a significant initial functional improvement and a low early complication rate.

Abstract
Osteonecrosis of femoral head is a rare but disabling condition that usually results in progressive femoral head collapse and secondary arthritis necessitating total hip arthroplasty if not treated appropriately in early stages. However, early diagnosis is challenging as the onset of disease is insidious and the symptoms and signs are usually minimal and nonspecific until it becomes advanced. Of several diagnostic modalities, magnetic resonance imaging (MRI) is considered the imaging method of choice with the highest sensitivity and specificity, while detection of potential risk factors is very important as well. Many investigators have developed several different classification systems; however, there still is controversy regarding the optimal classification system. Diagnostic methods and the evolution of different classification systems will be reviewed in this paper.

Abstract
OBJECTIVE To describe magnetic resonance imaging (MRI) features of Kager's fat pad inflammation in HIV-positive patients with lipodystrophy due to protease inhibitor treatment and posterior ankle pain. METHODS A case-control, cross-sectional study; group 1 included 14 HIV-positive patients using protease inhibitors, presenting lipodystrophy syndrome and having posterior ankle pain; group 2 (CGHIV-) included 112 HIV-negative patients without lipodystrophy syndrome who were being evaluated for posterior ankle pain; group 3 (CGHIV + 1) included 23 HIV-positive patients not using a protease inhibitor, without lipodystrophy syndrome and with posterior ankle pain; group 4 (CGHIV + 2) comprised 18 HIV-positive patients who were being treated with a protease inhibitor and had lipodystrophy syndrome but did not have posterior ankle pain. Images were evaluated for the presence of edema by two radiologists who were blinded to clinical features. Fisher's exact test was used to evaluate differences among the groups. Interobserver variation was tested using Cohen's kappa (κ) statistic. RESULTS The presence of edema within Kager's fat pad was strongly associated with symptoms in HIV-positive patients who had lipodystrophy (p ≤ 0.0001). Concordance between observers was excellent (κ > 0.9). CONCLUSION MRI findings of Kager's fat pad inflammation related to HIV/AIDS is a source of symptoms in HIV patients with posterior ankle pain using protease inhibitors and having lipodystrophy syndrome.

Abstract
Today, patients with human immunodeficiency virus (HIV) live long enough to develop chronic degenerative and HIV-associated joint disease. There is a growing population of patients infected with HIV who are candidates for total hip arthroplasty (THA). A total of 31 HIV-positive, non-hemophilic patients undergoing 41 THAs at our institution between 2000 and 2012 were identified. In-hospital medical complications were reported in 5 of 41 hips, all of which resolved prior to discharge. Deep infection developed in 1 of 41 hips and revision was required in 3 of 41 hips. These results suggest that low rates of complications and revision can be achieved in the HIV-positive, non-hemophilic population. We believe that with careful patient selection, THA may improve the quality of life in the HIV-positive population.

Abstract
Multifocal or multiple osteonecrosis (ON), defined by the involvement of 3 or more anatomic sites, is unusual, being observed in only 3%-10% of patients diagnosed with ON. We report the clinical characteristics of a cohort of 29 patients with multifocal ON from a single center and evaluate the prevalence of associated prothrombotic abnormalities in 26 of these patients. We conducted a retrospective study of all patients diagnosed with multifocal ON evaluated in our institution during the last 20 years. We recorded clinical manifestations and underlying diagnoses. A wide thrombophilic profile was performed, including antithrombin, protein C, protein S, lupus anticoagulant, anticardiolipin antibodies, activated protein C resistance, factor V Leiden, mutation G-20210-A of the prothrombin gene, and factor VIII. Coagulation test results were compared with those in a healthy control group and a group of patients with history of lower-extremity deep venous thrombosis. The mean age of the patients was 49.2 ± 15 years (range, 28-81 yr). The mean number of ON localizations per patient was 5.2 ± 2.3 (range, 3-11). Hips were the most commonly affected joint (82%), followed by knees (58%), shoulders (37%), and ankles (13%). Most patients had an underlying disease process, and 12 of 25 (48%) patients had coagulation test abnormalities. The most common alterations were high factor VIII levels and antiphospholipid antibody (aPL) positivity in 24% and 20% of cases, respectively. These abnormalities were more prevalent in patients with multifocal ON compared with patients in the control groups. Sixty-one percent of patients had a history of corticosteroid treatment. Patients with coagulation abnormalities had a higher number of ON localizations per patient (6.5 ± 2.7 vs. 3.88 ± 0.8; p = 0.002) and a higher prevalence of atypical ON localizations (25% vs. 0%; p = 0.05). In conclusion, in the present cohort of patients with multifocal ON, 48% of the patients had at least 1 prothrombotic factor, especially high levels of factor VIII and aPL. These findings have major implications for the diagnosis and treatment of multifocal ON and clearly indicate the need to perform a thrombophilic profile in these patients.

Abstract
BACKGROUND Symptomatic osteonecrosis of the joint is a frequent debilitating complication in patients who have been infected with the human immunodeficiency virus (HIV). In earlier reports, outcomes of primary total joint arthroplasty in such patients have been poor due to early failures, high infection rates, and increased complication rates. We report on the clinical and radiographic outcomes of primary total hip arthroplasty (THA) in nonhemophilic, HIV-infected patients as compared with the outcomes in a cohort of osteonecrosis patients who did not have this disease. METHODS Thirty-four HIV-infected patients (forty-four hips) who underwent primary THA for the treatment of osteonecrosis during the period of 2001 through 2008 were compared with a control cohort of seventy patients (seventy-eight hips) who also underwent THA for the treatment of osteonecrosis but did not have HIV or other high-risk factors for revision. The patients in the HIV study group (eleven women and twenty-three men) had a mean age of forty-eight years (range, thirty-four to eighty years) and were followed for a mean of seven years (range, four to eleven years). Evaluated outcomes included implant survivorship, Harris hip score, infection rate, activity score, postoperative Short-Form 36 (SF-36) health survey score, and radiographic outcome. RESULTS Kaplan-Meier survival analysis demonstrated no significant difference in aseptic implant survivorship between the HIV and comparison cohorts at the five-year (100% vs. 98%, respectively) and ten-year (95% vs. 96.5%, respectively) follow-up times. In addition, at the time of final follow-up, the mean postoperative Harris hip scores (85 points in the HIV group vs. 87 points in the comparison group), activity scores (5.7 points in the HIV group vs. 6.1 points in the comparison group), and SF-36 physical (43 points in the HIV group versus 46 points in the comparison group) and mental component summary scores (54 points in the HIV group versus 57 points in the comparison group) were statistically similar between the two cohorts. There were two late infections in the HIV cohort as compared with none in the comparison cohort. CONCLUSIONS Our results demonstrated excellent implant survivorship, clinical and radiographic outcomes, and minimal complications at the time of midterm follow-up in the HIV-infected patient group. We believe that the outcomes associated with primary THA are improving in this patient population as a result of better medical management; however, late infections are potential complications.

Abstract
The purpose of this study is to review a large series of HIV-infected patients who underwent total joint arthroplasty and identify potential risk-factors for infection. Sixty-nine HIV-infected arthroplasty cases were analyzed with 138 matched controls. Deep infection rate following total hip or knee arthroplasty was 4.4% (3 of 69) among HIV cases compared to 0.72% (1 of 138) among controls, yielding a non-significant 6.22 times increased odds of infection (95% CI 0.64-61.0, P=0.11). Kaplan-Meier survival curves for infection free survival and revision free survival revealed non-significantly decreased survival in HIV cases compared to controls (P=0.06 and P=0.09). Our results suggest that the rate of early joint infection following primary total joint arthroplasty in the HIV-infected population is lower than reported in a number of previously published studies.

Abstract
BACKGROUND Highly active antiretroviral therapy has prolonged the lifespan of individuals infected with human immunodeficiency virus (HIV). We hypothesized that the number of primary total joint arthroplasties performed in this population has been increasing and that HIV infection is not an independent risk factor for postoperative complications. METHODS The Nationwide Inpatient Sample for the years 2000 through 2008 was queried to identify patients who underwent primary total joint arthroplasty. HIV, comorbidities, and complications were identified with use of ICD-9-CM (International Classification of Diseases, Ninth Revision, Clinical Modification) codes. Data were analyzed with use of multivariate logistic regression, the Pearson chi-square test, and the Mann-Kendall trend test. RESULTS Of the estimated 5,681,024 admissions for primary total hip and knee arthroplasty in the United States during this period, 8229 (0.14%) were in patients who had HIV. Compared with HIV-negative patients (controls), infected patients were more likely to be younger, be male, and have a history of osteonecrosis, liver disease, drug use, and coagulopathy. The number of total hip and total knee arthroplasties in HIV-positive patients increased from 2000 to 2008 (p < 0.05). Seventy-nine percent (6499) of the total joint arthroplasties in the HIV-positive patients involved the hip. Compared with HIV-negative patients undergoing total hip arthroplasty, HIV-positive patients were more likely to develop acute renal failure (1.3% compared with 0.8%, p = 0.04), develop a wound infection (0.6% compared with 0.3%, p = 0.02), and undergo postoperative irrigation and debridement (0.2% compared with 0.1%, p = 0.01). They were less likely to have a myocardial infarction (0.4% compared with 0.9%, p = 0.04). There was no difference in total complications (8.3% compared with 7.8%, p = 0.52). Similarly, there was no difference in total complications in patients undergoing total knee arthroplasty (7.8% compared with 8.0%, p = 0.76). HIV was not an independent risk factor for complications in total hip arthroplasty (odds ratio [OR], 1.18; 95% confidence interval [CI], 0.95 to 1.47) or total knee arthroplasty (OR, 0.78; 95% CI, 0.49 to 1.25). CONCLUSIONS The incidence of primary total joint arthroplasty in HIV-positive patients has been increasing. These patients were at slightly higher risk of certain immediate postoperative complications because of a higher rate of medical comorbidities. HIV infection was not an independent risk factor for the total rate of perioperative complications. LEVEL OF EVIDENCE Prognostic Level II.

Abstract
Recent advances in the medical management of patients with human immunodeficiency virus (HIV) have led to improvement in their life expectancy. The growing numbers of HIV-positive patients are now living long enough to develop end-stage arthritis, as well as other long-term musculoskeletal complications of HIV infection and treatment. This has resulted in an increased demand for total joint arthroplasty among these individuals. However, the safety and outcomes of such procedures are frequently questioned in published reports. Although increased complication rates have often been reported, most studies have reported on joint arthroplasties in HIV patients with hemophilia. The most widely reported complications in both HIV-negative and positive hemophiliac patients are aseptic loosening and postoperative infection. A possible relationship between the rate of these complications and cluster of differentiation (CD4) lymphocyte count has also been proposed. In addition to hemophilia, other factors frequently comorbid with HIV infection, such as intravenous drug use, can further complicate the clinical outcomes of these individuals following total joint replacement procedures. Physicians treating HIV positive patients must remain aware of the risks and outcomes of total joint surgery in this group when counseling them on treatment options.

Abstract
BACKGROUND A high incidence of nontraumatic osteonecrosis has been reported in HIV-infected patients. We investigated the levels of D-dimer and C-reactive protein (CRP) in a cohort of HIV-infected adults with and without osteonecrosis of the femoral head. METHODS Forty-three HIV-infected patients with osteonecrosis of the femoral head and a comparison group of 50 HIV-infected patients with negative MRI of the hips and for whom serial plasma samples were available were included. D-dimer and CRP levels were measured prior to and at the time of diagnosis for osteonecrosis patients, at the time of negative MRI of the hips for controls, and at least 6 months later for both groups. RESULTS Biomarker levels were elevated at the time of diagnosis in the osteonecrosis cohort compared with controls. Median D-dimer value was 0.32 μg/ml in the osteonecrosis group compared with less than 0.22 μg/ml in the control group (P = 0.016). For CRP, the corresponding values were 2.52 mg/l and 1.23 mg/l (P = 0.003). Postdiagnosis, D-dimer and CRP levels were also elevated in the osteonecrosis patients compared with controls. Linear regression demonstrated a rise in D-dimer levels from prediagnosis to diagnosis in the osteonecrosis patients whereas CRP levels did not change significantly over time. CONCLUSION Compared to controls, patients who developed osteonecrosis had elevated levels of D-dimer and CRP at diagnosis. D-dimer levels increased whereas CRP levels did not change significantly from prediagnosis to diagnosis. These data suggest that patients with higher levels of inflammation are at an increased risk of osteonecrosis.

Abstract
OBJECTIVE To estimate the incidence rate of nontraumatic osteonecrosis of the femoral head (ONFH) in the Japanese population. METHODS A survey was conducted to ascertain newly identified patients with nontraumatic ONFH in the Specified Disease Treatment Research Program of Fukuoka Prefecture (population 5 million) between 1999 and 2008. Distributions of age and sex in this population were investigated. Crude incidence rates of nontraumatic ONFH were calculated, and age-adjusted incidence rates were estimated by adjusting the crude values against those for the Japanese standard population in each year. RESULTS In Fukuoka Prefecture, 1,244 newly identified patients with nontraumatic ONFH were recruited into the Japanese subsidy program over the span of 10 years. The ratio of men to women was 1.6, comprising 758 men (61%; mean age 48 years) and 486 women (39%; mean age 56 years). The crude incidence rate of nontraumatic ONFH in the 10-year period was 2.58 cases per 100,000 person-years (range 1.54-3.66). The mean age-adjusted incidence rate was 2.51 cases per 100,000 person-years. CONCLUSION This study showed that the incidence rate of nontraumatic ONFH was 2.51 cases per 100,000 person-years in the Japanese population.
