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.

Intra-operative fractures in primary total knee arthroplasty - a systematic review

Background: One of the rare complications of primary total knee arthroplasty is intra-operative fracture. Intraoperative fracture during revision knee arthroplasty has been well-documented but there is limited literature on fractures occurring during primary knee arthroplasty. We conducted a systematic review of the literature to compare and contrast the various studies to clearly define the predisposing factors, incidence, and characteristics of the fracture itself and to arrive at a consensus on the management and prevention of intra-operative fractures during primary knee arthroplasty. Methods: The PubMed/Medline, Cochrane, Scopus and Embase databases were searched using keywords “intraoperative fracture”, “distal femoral fracture”, “tibial fracture”, “patella fracture” and “primary total knee arthroplasty”. A total of 158 articles were retrieved and after further filtration and exclusion processing, 10 articles that evaluated intra-operative fractures in primary total knee arthroplasty were included for the review. Results: The reported incidence of intra-operative fractures varied from 0.2% to 4.4%. A higher incidence in female patients with a male to female ratio of 0.4 was reported. Posterior stabilized (PS) total knee arthroplasty was associated with higher risk of intra-operative femoral fractures by many authors in this review. Timing of occurrence and location of the intra-operative fractures can vary widely, with femoral fractures occurring more commonly during bone preparation, trialing and impaction of the final implant and tibial fractures occurring during preparation for the tibial keel and impaction of the tibial component. Conclusions: Intra-operative fractures during primary total knee arthroplasty are rare with higher risk associated with osteoporosis, rheumatoid arthritis, advanced age, female gender, chronic steroid use, metabolic bone disorders, PS type of femoral implant and difficult surgical exposure of the knee joint due to severe deformities. A plethora of management options have been utilized according to surgeon preference. Standard principles of fracture fixation and arthroplasty principles should be followed to achieve stable internal fixation and any unstable fracture site should be bypassed with the utilization of stemmed components. Satisfactory radiographic and functional outcome can be expected with appropriate treatment.

Background Chronic kidney disease (CKD) is a growing disease that affects millions of people in the USA every year. Many CKD patients progress to end-stage renal disease (ESRD), necessitating the use of hemodialysis to alleviate symptoms and manage kidney function. Furthermore, many of these patients have lower bone quality and experience more postoperative complications. However, there is currently limited information on hospitalization information and perioperative complications in this population following procedures such as total knee arthroplasty (TKA). The purpose of this study was to assess the patient characteristics, demographics, and prevalence of postoperative problems among dialysis patients who received TKA. Methods In this retrospective study, we used the Nationwide Inpatient Sample (NIS) data from 2016 to 2019 to analyze the incidence of perioperative complications, length of stay (LOS), and the cost of care (COC) among patients undergoing TKA who were categorized as dialysis patients, compared with those who were not. Propensity matching was conducted to consider associated factors that may influence perioperative complications. Results From 2016 to 2019, 558,371 patients underwent TKAs, according to the National In-Sample (NIS) database. Of those, 418 patients (0.1%) were in the dialysis group, while the remaining 557,953 patients were included in the control group. The mean age of the dialysis group was 65.4 ± 9.8 years, and the mean age in the control group was 66.7 ± 9.5 years (p = 0.006). After propensity matching, dialysis group patients had a higher risk of receiving blood transfusions [odds ratio (OR): 2; 95% confidence interval (CI): 1.2, 3.4] and a significantly larger COC in comparison to those in the control group (91,434.3 USD versus 71,943.6 USD, p < 0.001). In addition, dialysis patients had significantly higher discharges to another facility, as compared with the control group patients. Conclusions The dialysis group had a significantly higher cost of care, higher rates of requiring blood transfusion, and more cases of being discharged to another facility than non-dialysis patients. This data will help providers make informed decisions about patient care and resource allocation for dialysis patients undergoing TKA.
