Minimum twenty-year follow-up of fixed-vs mobile-bearing total knee arthroplasty: Double blinded randomized trial.

Introduction: Mobile-bearing (MB) inserts, designed to minimize aseptic loosening and to reduce contact stresses leading to polyethylene wear, are an alternative to fixed-bearing (FB) inserts. Most studies have shown no significant difference between MB and FB constructs, and there is limited long-term data comparing the two constructs [1,2,3,4]. The purpose of this study was to report the outcomes of a randomized controlled trial comparing MB versus FB inserts on patients with minimum 20-year follow-up.

Reverse shoulder arthroplasty for proximal humerus fractures and reverse shoulder arthroplasty for elective indications should have separate Current Procedural Terminology (CPT) codes.

Background: Reverse shoulder arthroplasty (RSA) for fracture currently shares a single Current Procedural Terminology (CPT) code with RSA for arthropathy despite potential differences in patient factors, procedural demands, postoperative care and needs, and overall hospital systems' resource utilization. We hypothesize that patients indicated for RSA for fracture will have greater medical complexity, require longer operative duration, have higher complication rates, demonstrate inferior functional outcomes, and require greater health care cost expenditures compared to a cohort undergoing RSA for rotator cuff arthropathy.

Methods: A total of 383 RSAs were retrospectively reviewed from January 2011 to December 2020.

Patellar resurfacing in contemporary total knee arthroplasty: Frequency of complications in a matched cohort.

Introduction: Optimum patient selection and outcomes following patellar resurfacing are ongoing debates amongst the arthroplasty community. This study compared the outcomes of patients who had a total knee arthroplasty (TKA) with patellar resurfacing to those left with their native patella.

Methods: A retrospective review of 1941 TKAs performed between 2016 and 2020 was conducted.

Incidence and Risk Factors for Acid-fast Bacillus/Fungal Culture Positivity in Primary, Conversion, and Revision Hip and Knee Arthroplasty.

Introduction: Previous literature has reported minimal incidences of positive fungal/AFB cultures, questioning the routine use of these tests. With growing concern for excessive use, predictive factors for patients at higher risk for intraoperative AFB/fungal infections would help surgeons limit unnecessary testing. This study evaluates the positivity rate and predictive factors of positive fungal and/or acid-fast bacillus (AFB) cultures after primary, conversion, or revision hip and knee arthroplasty.

Accuracy of intraoperative approximation of pelvic tilt using preoperative standing radiographs.

Background: Anterior approach surgeons who utilize intraoperative fluoroscopy often try to match a preoperative radiograph as a reference for intraoperative cup position. Every degree of inaccuracy in tilt leads to a roughly 0.7° change in anteversion.

Treatment of tegmen dehiscence using a middle fossa approach and autologous temporalis fascia graft: Outcomes from a single center.

Introduction: Although bony defects of the tegmen surface are relatively common, the majority of dehiscences are asymptomatic. For those who experience symptoms, there is a wide spectrum of relatively benign manifestations such as hearing loss and otorrhea to potentially more serious but rare sequelae such as epilepsy and meningitis. Surgical management of tegmen dehiscences (TDs) can help prevent these symptoms.
