Does the amount of noise generated differ between manual and robotic TJA?

Background: The purpose of this study was to evaluate whether noise that is generated during manual and robotic-assisted total joint arthroplasty (TJA) differs and if that noise exceeds the Occupational Safety Health Administration (OSHA) action limits.

Methods: Personal dosimeters were used to record the decibel (dB) level during manual and robotic-assisted total hip and knee arthroplasty (THA/TKA). The primary surgeon wore the dosimeter on their person.

Isolated Femoral Component Revision Outcomes in the Setting of Acute Periprosthetic Femoral Fractures.

Background: While periprosthetic femoral fracture (PFF) is not the most common reason for revision of a primary total hip arthroplasty (THA), it represents a common problem in the acute postoperative period. During this time, undergoing revision surgery has been found to have increased risks of complications. The goal of this study was to evaluate the outcome of patients who experienced an isolated femoral revision for a PFF acutely after primary THA.

Do Outcomes Differ After Medial Unicompartmental Knee Arthroplasty Based on Indications? A Prospective Cohort Study.

Background: Unicompartmental knee arthroplasty (UKA) has grown recently, highlighted by shorter recovery periods and positive clinical outcomes. This study's purpose was to determine whether clinical outcomes differ after medial UKA between patients indicated with strict versus liberal criteria as defined by established literature.

Methods: We prospectively enrolled 94 patients (110 knees) undergoing UKA by a single surgeon.

Hyaluronic acid injections administered within two months prior to total knee arthroplasty increase the risk for periprosthetic joint infection.

Background: It remains unknown how timing of preoperative intra-articular knee hyaluronic acid (HA) injections impacts risk for developing postoperative periprosthetic joint infection (PJI) following total knee arthroplasty (TKA).

Methods: The PearlDiver Mariner database was utilized to identified patients undergoing primary TKA between 2015 and 2022 who received an HA injection without a corticosteroid injection within 12 months prior to surgery. The HA cohort was matched 1:1 to a control cohort undergoing no preoperative injections (corticosteroid or HA).

The Ideal Timing of Bilateral Total Knee Arthroplasty: Simultaneous Versus Staged.

Objectives: The ideal timing for patients undergoing bilateral total knee arthroplasty (TKA) remains unknown. The purpose of this study was to compare 90-day outcomes between unilateral, simultaneous bilateral, and staged bilateral TKA.

Methods: The PearlDiver database was used to retrospectively identify 231,119 patients undergoing primary TKA during 2015-2020, of which 67,956 (29.

Three Differing Methods of Treating Intraoperative Nondisplaced Calcar Fractures Demonstrate Similar Radiographic Stem Subsidence.

Background: Several management strategies have been described to treat intraoperative calcar fractures during total hip arthroplasty (THA), including retaining the primary implant and utilizing cerclage cables (CCs) or switching the implant to one that bypasses the fracture and achieves diaphyseal fixation. However, the radiographic and clinical outcomes of these differing strategies have never been described and compared.

Methods: We retrospectively identified 50 patients who sustained an intraoperative calcar fracture out of 9,129 primary total hip arthroplasties (0.

Invasive Gastrointestinal Endoscopy Following Total Joint Arthroplasty Increases the Risk for Periprosthetic Joint Infection.

Background: The safety of postoperative colonoscopy and endoscopy following total joint arthroplasty (TJA) remains largely unknown. The objective of this study was to characterize the effect of gastrointestinal endoscopic procedures after TJA on the risk of postoperative periprosthetic joint infection (PJI).

Methods: Using a large national database, patients who underwent an endoscopic procedure (colonoscopy or esophagogastroduodenoscopy (EGD)) within 12 months after primary TJA were identified and matched in a 1:1 fashion based on procedure (primary total knee arthroplasty (TKA) versus total hip arthroplasty (THA)), age, sex, Charlson Comorbidity Index (CCI), and smoking status with patients who did not undergo endoscopy.

Outpatient Total Knee Arthroplasty Shows Decreasing Complication Burden From 2010 to 2020.

Background: The number of total knee arthroplasties (TKAs) performed on an outpatient basis continues to increase. The purpose of this study was to compare complication rates over the last decade to evaluate trends in the safety of outpatient TKA.

Methods: Patients who underwent TKA from 2010 to 2020 from a large administrative claims database were retrospectively identified and stratified based on the year of surgery.

COVID-19 Infection After Total Joint Arthroplasty Is Associated With Increased Complications.

Background: The impact of a postoperative diagnosis of COVID-19 in patients undergoing total joint arthroplasty (TJA) remains unknown. The objective of this study is to characterize the effect of COVID-19 infection following TJA on perioperative complication rates.

Methods: The Mariner database was queried for patients undergoing total hip and total knee arthroplasty from January 2018 to April 2020.
