Introduction: total hip arthroplasty (THA) is a successful surgical intervention for end-stage hip arthritis, however, it is not extent for complications. The risk of instability after THA with conventional design is up to 7% for primary procedures and 5-20% for revisions. The purpose of this study is to document the complications that occur with the double mobility prosthetic design.

Department of Orthopedic Surgery, University of California, Los Angeles, Santa Monica, CA, USA.
Background: Revision hip and knee arthroplasty volume continues to rise, and total femur replacement (TFR) remains a key salvage option in patients with extensive bone loss. Prior research has demonstrated mixed results of this procedure, and this study aimed to characterize the outcomes of nononcologic TFR in one of the largest single-center modern series.
Methods: A retrospective analysis was conducted on 23 nononcologic TFR procedures performed on 22 patients between 2012 and 2021.

Total hip arthroplasty (THA) is a highly effective surgical intervention for end-stage hip joint disorders. While common complications such as infection, dislocation, and prosthetic loosening are well-documented, rarer complications remain underreported. One such complication is foreign body interposition on the bearing surface, which can compromise joint mechanics and adversely affect outcomes.

January 2025
Department of Orthopedics, First Affiliated Hospital of Xinjiang Medical University, Urumqi, PR China.
Background: Bacteremia is sometimes observed in patients with prosthetic joint infection (PJI), and it is associated with a lower likelihood of infection control. However, the prevalence and association of bacteremia in chronic PJI remain unknown.
Questions/purposes: (1) What percentage of patients are diagnosed with bacteremia at the time of hospital admission and before surgery for chronic PJI? (2) What clinical factors are associated with positive blood cultures? (3) To what degree are positive blood cultures associated with infection-free implant survival in patients with chronic PJI?
Methods: This prospective study was conducted at a single academic institution from June 2021 to August 2022.
Povidone-Iodine Versus Saline Irrigation on Reduction of Surgical Site Infections in Total Hip and Knee Arthroplasty: A Retrospective, Propensity-Matched Cohort.
Surg Infect (Larchmt)
January 2025
New England Baptist Hospital, Boston, Massachusetts, USA.
Surgical site infection (SSI) after total hip and knee arthroplasty (THA/TKA) is a major complication leading to morbidity and mortality. Perioperative irrigation, frequently with antiseptic compounds including povidone-iodine (PI), is the standard of care in reducing SSI. Evidence supporting the value of PI versus nonantiseptic substances varies.
