Extended Oral Antibiotic Prophylaxis and Periprosthetic Joint Infection-Free Survivorship After Primary Total Hip Arthroplasty.

Background: Several studies have presented findings in favor of using extended oral antibiotic (EOA) prophylaxis to reduce periprosthetic joint infection (PJI) after primary total hip arthroplasty (THA) in patients at high risk for infection. To date, there is a paucity of evidence examining this topic from large retrospective databases. This study explored 90-day complication rates and 2-year PJI-free survivorship in a large cohort of patients receiving EOA prophylaxis after primary THA.

Extended oral antibiotic prophylaxis and PJI-free survivorship after primary total knee arthroplasty.

Introduction: Recent evidence has emerged supporting the use of extended oral antibiotic (EOA) prophylaxis after primary total knee replacement (TKA) to reduce periprosthetic joint infection (PJI) in high-risk patients. However, much of the evidence stems from single-institution series with limited sample sizes. This study aimed to explore the impact of EOA on complications and infection-free survivorship in a large cohort of patients after primary TKA.

A Systematic Review and Meta-Analysis of Total Knee Arthroplasty after Tibial Plateau Fracture Fixation.

Introduction: Tibial plateau fractures are common injuries that pose a significant risk of post-traumatic osteoarthritis (PTOA) despite surgical fixation. Though total knee arthroplasty (TKA) has been proven as a viable treatment option for PTOA, there is a higher risk of postoperative complications in patients with prior tibial plateau fracture (TPF). This systematic review aimed to evaluate surgical considerations and outcomes of TKA in patients with prior TPF fixation.

The subjective hip value: a retrospective validation study in primary total hip arthroplasty.

Background: The hip dysfunction and osteoarthritis outcome score for joint replacement (HOOS JR) has been widely used to assess patient hip function. The subjective hip value (SHV) has become increasingly recognized as an efficient single-question survey for assessing hip joint function. This study aimed to determine the psychometric properties of the SHV in evaluating hip function in patients undergoing total hip arthroplasty (THA) in correlation with the traditional HOOS JR.

Administration of a Methylprednisolone Taper and Complication Rates Following Total Knee Arthroplasty: A Multicenter Retrospective Study.

Background: Most patients undergoing total knee arthroplasty (TKA) report moderate to severe pain in the acute postoperative period. Recent preliminary data have suggested that a short course of oral corticosteroid may improve early postoperative pain after various orthopedic operations, but the safety of this practice has not been rigorously evaluated in larger patient populations. The purpose of this study was to evaluate complication rates in patients receiving a methylprednisolone taper (MT) vs controls after primary TKA.

Characterizing the Cost Trends of Readmissions After Aseptic Revision Total Knee Arthroplasty.
