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
Background Metabolic disorders presenting in HIV-infected patients on antiretroviral therapy (ART) may increase the risk of osteoarthritis. However, structural changes of the knee in HIV infected subjects are understudied. The aim of this study is to investigate knee cartilage degeneration and knee structural changes over 8 years in subjects with and without HIV infection determined based on the use of ART. Methods We studied 10 participants from the Osteoarthritis Initiative who received ART at baseline and 20 controls without ART, frequency matched for age, sex, race, baseline body mass index (BMI) and Kellgren & Lawrence grade. Knee abnormalities were assessed using the whole-organ magnetic resonance imaging score (WORMS) and cartilage T2 including laminar and texture analyses were analyzed using a multislice-multiecho spin-echo sequence. Signal abnormalities of the infrapatellar fat pad (IPFP) and suprapatellar fat pad (SPFP) were assessed separately using a semi-quantitative scoring system. Linear regression models were used in the cross-sectional analysis to compare the differences between ART/HIV subjects and controls in T2 (regular and laminar T2 values, texture parameters) and morphologic parameters (subscores of WORMS, scores for signal alterations of IPFP and SPFP). Mixed effects models were used in the longitudinal analysis to compare the rate of change in T2 and morphological parameters between groups over 8 years. Results At baseline, individuals on ART had significantly greater size of IPFP signal abnormalities (P = 0.008), higher signal intensities of SPFP (P = 0.015), higher effusion scores (P = 0.009), and lower subchondral cysts sum scores (P = 0.003) compared to the controls. No significant differences were found between the groups in T2-based cartilage parameters and WORMS scores for cartilage, meniscus, bone marrow edema patterns and ligaments (P > 0.05). Longitudinally, the HIV cohort had significantly higher global knee T2 entropy values (P = 0.047), more severe effusion (P = 0.001) but less severe subchondral cysts (P = 0.002) on average over 8 years. Conclusions Knees of individuals with HIV on ART had a more heterogeneous cartilage matrix, more severe synovitis and abnormalities of the IPFP and SPFP, which may increase the risk of incident knee osteoarthritis.
