  1. Prosthetic joint infection (PJI) is a devastating complication. Studies have suggested reduction in PJI with the use of ceramic bearings.
  2. Limb length discrepancy (LLD) after total hip arthroplasty may affect clinical outcomes and patient satisfaction. Preoperative LLD estimates on anteroposterior (AP) pelvic radiographs fail to account for anatomical limb variation distal to the femoral reference points. The objective of this study was to determine how variations in lower limb skeletal lengths contribute to true LLD.
  3. Obesity poses a challenge to thromboembolic prophylaxis following total joint arthroplasty. The purpose of this study was to evaluate a weight-based aspirin dosing regimen for prevention of venous thromboembolism (VTE) following TJA.
  4. The objective of this study is to provide the 5 year follow-up results of a randomised study comparing conventional versus electromagnetic (EM) computer navigated total knee arthroplasty (TKA).
  5. Patients often ask when they can safely return to driving a car following total joint arthroplasty (TJA). Most prior research has relied on driving simulators. Our study sought to learn more about real world patient experiences in returning to driving after total knee arthroplasty (TKA) or total hip arthroplasty (THA).
  6. Statins have a variety of pleiotropic effects that could be beneficial for patients undertaking total knee or hip arthroplasty. In vitro and in vivo animal models suggest the beneficial effects of statins through bone formation and modulating proinflammatory cytokines triggered by implant debris. However, statins also exhibit antimicrobial action and may reduce the risk of revision surgery via reducing the risk of infection. We sought to explore the relationship between statin use and prosthetic joint infection (PJI) after total knee or hip arthroplasty.
  7. Revision total knee arthroplasty (TKA) is associated with a higher complication rate and a greater cost when compared to primary TKA. Based on patient choice, referral or patient transfers, revision TKAs are often performed in different institutions by different surgeons than the primary TKA. The aim of this study was to evaluate the effect of hospital size, teaching status, and revision indication on the migration patterns of failed primary TKA in patients 65 years-of-age and older.
  8. On December 20, 2020, the Centers for Medicare and Medicaid Services (CMS) finalized its proposed rule: CMS-1734-P. This 2021 Final Rule significantly changed Medicare total joint arthroplasty (TJA) reimbursement. The precise impact on surgeon productivity and reimbursement is unknown. In the present study, we sought to model the potential impact of these changes for multiple unique practice configurations.
  9. The patient reported outcome measurement information system (PROMIS) was developed by the NIH to collect outcome data in rapid dynamic fashion on electronic platforms. The potential role of PROMIS in monitoring pain and function in young THA patients has been under-investigated. The purpose of this study is to investigate correlation between PROMIS Physical Function (PF) and PROMIS Pain Interference (PI) and legacy scores with similar considerations.
  10. Optimum venous thromboembolism (VTE) prophylaxis for patients undergoing total hip or knee arthroplasty remains undefined. The purpose of this study was to compare complication rates among total joint arthroplasty patients using either low-dose aspirin (75 mg once daily) or low-molecular-weight heparin (LMWH; Fragmin/dalteparin 5000 U) for VTE prophylaxis.
  11. Registry data suggest increasing rates of early revisions after total hip arthroplasty (THA). We sought to analyze modes of failure over time following index THA to identify risk factors for early revision.
  12. People with cerebral palsy (CP) may be considered for total hip arthroplasty (THA). However, short- and long-term outcomes after THA in this population remain poorly characterized.
  13. Osteoarthritis is a chronic musculoskeletal condition that frequently affects the hip and knee joints. Given the burden associated with surgical intervention for hip and knee osteoarthritis, patients continue to search for potential non-operative treatments. One biologic therapy with mixed clinical and basic science evidence for treating osteoarthritis is platelet-rich plasma injections into the affected joint. We used the Google Trends tool to provide a quantitative analysis of national interest in platelet-rich plasma injections for hip and knee osteoarthritis.
  14. This study examines cobalt levels and psuedotumor characteristics in a non-recalled modular femoral prosthesis. We sought to determine relationships between serum cobalt levels and pseudotumors following modular and metal-on-metal (MoM) total hip arthroplasty (THA), the location and size of pseudotumors, and changes to pseudotumor grade over time.
  15. Ceramic-on-Ceramic (CoC) bearings are becoming increasingly popular in primary total hip arthroplasty (THA). To enhance CoC liner exchange in case of revision surgery metal-backed liner systems have been proposed. Little is known about the clinical performance of these implants. The purpose of this study was to evaluate a metal-backed liner implant system for primary THA.
