Fixation or Revision for Periprosthetic Fractures: Epidemiology, New Trends, and Projections in the United States.

Background: Periprosthetic fractures can be devastating complications after total joint arthroplasty (TJA). The management of periprosthetic fractures is complex, spanning expertise in arthroplasty and trauma. The purpose of this study was to examine and project trends in the operative treatment of periprosthetic fractures in the United States.

Why and What Happens to Patients Younger Than 60 Years Who Need Revision Total Knee Arthroplasty?

Background: With the increasing number of young patients undergoing primary total knee arthroplasty (TKA), there will be an increase in the number of patients who require revision. While the results of TKA in younger patients are well known, there is little information regarding to the outcomes of revision TKA in this population. The purpose of this study was to evaluate the clinical outcomes in patients <60 years of age undergoing aseptic revision TKA.

Wound complications following revision total knee arthroplasty: Prevalence and outcomes.

Background: Wound complications following revision TKA can be catastrophic and can compromise joint and even limb. The purpose of this study was to determine the prevalence of superficial wound complications requiring return to the OR in revision TKA, rates of subsequent deep infection, factors that increase the risk of superficial wound complications, and the outcomes of revision TKA following development of superficial wound complications.

Methods: We retrospectively reviewed 585 consecutive TKA revisions with at least two years follow-up, including 399 aseptic revisions and 186 reimplantations.

Profound Impact of Insurance Payor and Socioeconomic Status in Total Hip Arthroplasty Outcomes: Results From a High Volume Tertiary Care Center.

Background: Dual eligible Medicare/Medicaid patients undergoing total hip arthroplasty (THA) have worse outcomes compared to other insurance payors. Prior literature fails to control for the heterogeneity of care provided amongst a large cohort of hospitals and surgeons as well as differences in patient populations treated. This study compares dual eligible THA patients and Medicaid and Medicare only THA patients at a single high volume tertiary center.

Does Dual-Eligible Medicare/Medicaid Insurance Status as a Surrogate for Socioeconomic Status Compromise Total Knee Arthroplasty Outcomes?

Background: Medicare/Medicaid dual-eligible patients who undergo primary total knee arthroplasty (TKA) demonstrate poor outcomes when compared to patients with other payers. We compare Medicare/Medicaid dual-eligible patients vs Medicare and Medicaid only patients at a single hospital center.

Methods: All patients who underwent TKA for aseptic arthritis between August 9, 2016 and December 30, 2020 with either Medicare or Medicaid insurance were retrospectively reviewed.

Does a 2-Stage Debridement Result in Higher Rates of Implant Retention Compared With Single Debridement Alone?

Background/methods: We retrospectively reviewed 89 patients with acute prosthetic joint infection treated with debridement, antibiotics, and implant retention (DAIR) or 2-DAIR. Patients had <3 weeks of symptoms and met Musculoskeletal Infection Society criteria for infection. Sixty-three patients were treated with DAIR, whereas 26 patients were managed using a 2-DAIR protocol where patients underwent initial debridement, antibiotic bead placement, and subsequent return to the operating room at an average of 16.

Atraumatic Index Finger Flexor Tendon Rupture as a Presenting Sign of Capitate Osteonecrosis: A Report of 2 Cases.

Case: We present 2 cases of spontaneous index finger (IF) flexor tendon ruptures because of previously undiagnosed osteonecrosis (OA) of the capitate. Imaging revealed fragmentation of the capitate, and patients were treated with excision or fixation of the bony fragments with tendon repair. At the final follow-up, both patients had functional digital range of motion.

Excision and Reconstruction of Alveolar Rhabdomyosarcoma Involving the Achilles Tendon in a Pediatric Patient: A Case Report.

Case: We describe a case of a 9-year-old boy who presented with a left calf mass consistent with alveolar rhabdomyosarcoma involving the Achilles tendon. The patient underwent radical resection of the Achilles tendon and Achilles tendon allograft reconstruction. At 2.

Disruption of the Gut Microbiome Increases the Risk of Periprosthetic Joint Infection in Mice.

Background: Periprosthetic joint infection (PJI) is one of the most devastating complications of total joint arthroplasty. Given the mortality and morbidity associated with PJI and the challenges in treating it, there has been increased interest in risk factors that can be modified before surgery. In this study, we used a novel mouse model to consider the role of the gut microbiome as a risk factor for PJI.

Predictors of In-Hospital Ambulatory Status Following Low-Energy Hip Fracture Surgery.

Introduction: Twenty-five percent to seventy-five percent of independent patients do not walk independently after hip fracture (HF), and many patients experience functional loss. Early rehabilitation of functional status is associated with better long-term outcomes; however, predictors of early ambulation after HF have not been well described.

Purposes: To assess the impact of perioperative and patient-specific variables on in-hospital ambulatory status following low-energy HF surgery.
