All-Polyethylene Tibias Equal to Metal-Backed Tibias in Primary Total Knee Arthroplasty: A Systematic Review and Meta-Analysis.

We sought to conduct a systematic review of the literature and a meta-analysis of post-operative outcomes following TKA with an all-polyethylene tibial (APT) or a metal-backed tibial component (MBT). A systematic review of the literature was conducted to identify all studies comparing APT and MBT for TKA based upon rates of complications, revisions, reoperation, and patient-reported outcomes. Data was pooled and relative risk of each outcome measure at short (< 5 year), mid (5-10 year), and long (> 10 year) follow-up was calculated.

Incidence of heterotopic ossification following total hip arthroplasty by approach: a systematic review.

Background: Heterotopic ossification (HO) formation has been increasingly recognized as a complication of major orthopedic surgeries, particularly total hip arthroplasty (THA). Though, the overall incidence of HO following THA has been well-documented, it is often not reported by severity or by surgical approach.

Questions/purposes: (1) What are the demographics of patients with HO? (2) What is the severity of HO following THA using the Brooker classification? (3) What is the incidence and class of HO following different THA approaches (anterior, posterior, posterolateral, anterolateral, superior, lateral, trans-gluteal)? (4) What are the number and training level of surgeons who performed each procedure?

Methods: The PubMed, Embase, and Web of Science databases were queried, and PRISMA guidelines were followed.

Impact of Reporting Bias, Conflict of Interest, and Funding Sources on Quality of Orthopaedic Research.

Background: Influence of factors like reporting outcomes, conflicts of interest, and funding sources on study outcomes, particularly positive outcomes in orthopedics, remains underexplored. As transparency of partnerships in orthopaedic surgery through conflicts of interest statements has increased over the years, there has been a lack of focus on the value of these partnerships in influencing study outcomes. We aimed to investigate the associations between reporting outcomes, conflicts of interest, and sources of funding on study outcomes.

Postoperative Opioid Dependence in Patients Undergoing Either Total or Reverse Shoulder Arthroplasty for Proximal Humerus Fracture Fixation.

Introduction: In elderly patients who have proximal humerus fractures, treatment commonly involves total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (RSA). Following these procedures, patients often require opioids for postoperative analgesia. This common scenario is of clinical and societal importance, as increased postoperative opioid usage has been shown to worsen outcomes and increase the likelihood for dependence.

Pre-operative corticosteroid injection within 1 month of total shoulder arthroplasty is associated with increased risk of periprosthetic joint infection.

Introduction: Corticosteroid injections (CSI) may increase the risk of peri-prosthetic infections (PJI) following total shoulder arthroplasty (TSA). Our study specifically assessed the risk of PJI in patients who received CSI: (1) less than 4 weeks prior to TSA; (2) 4-8 weeks prior to TSA; and (3) 8-12 weeks prior to TSA.

Materials And Methods: A national all-payer database was queried to identify patients who underwent TSA with a shoulder osteoarthritis diagnosis from October 1, 2015 to October 31, 2020 (n = 25,422).

A call to "own the bone": osteoporosis is a predictor for adverse two-year outcomes following total hip and knee arthroplasty.

Purpose: While bone health is instrumental in orthopedic surgery, few studies have described the long-term outcomes of osteoporosis (OP) in patients undergoing total hip (THA) or knee (TKA) arthroplasties.

Methods: Using the New York State statewide planning and research cooperative system database, all patients who underwent primary TKA or THA for osteoarthritis from 2009 to 2011 with minimum 2-year follow-up were identified. They were divided based on their OP status (OP and non-OP) and 1:1 propensity score matched for age, sex, race, and Charlson/Deyo index.

Does preoperative corticosteroid injection increase the risk of periprosthetic joint infection after reverse shoulder arthroplasty?

Background: Corticosteroid injections (CSIs) are used for the symptomatic management of osteoarthritis. However, their use may contaminate the joint space and pose an increased risk of periprosthetic joint infection (PJI) following reverse shoulder arthroplasty (RSA). Therefore, the purpose of this study was to assess whether there is any association between the timing of CSI and the incidence of PJI at 90 days, 1 year, and 2 years postoperatively.

Current Concepts and Advances of Three-Dimensional Printing in Reconstructive Musculoskeletal Oncology: A Systematic Review.

Three-dimensional printing has the potential to advance current surgical practice, by way of anatomical and pathological structure analysis and customized implant manufacturing. Applications for this technology include pre-operative planning, prosthesis customization, and bioprinting. A comprehensive literature review of PubMed, Embase, Cochrane Library, Scopus, and Web of Science databases was conducted to extract all studies adopting three-dimensional printing in the operative management of primary and metastatic musculoskeletal tumors.

Radiation exposure in fluoroscopy-guided anterior total hip arthroplasty: a systematic review.

Purpose: To investigate the average fluoroscopy time, as well as the patient and surgical staff average radiation exposure in the context of intraoperative fluoroscopy use during anterior total hip arthroplasty (THA).

Methods: PubMed, Cochrane, Embase, Web of Science and Scopus were systematically searched for studies pertaining to intraoperative anterior THA fluoroscopy (PROSPERO ID 258049). The comprehensive literary search was conducted using "THA," "fluoroscopy" and "radiation exposure" as the search criteria, which resulted in 187 total papers.

Emergency management of stroke in the era of mechanical thrombectomy.

Emergency management of stroke has been directed at the delivery of recombinant tissue plasminogen activator (tPA) in a timely fashion. Because of the many limitations attached to the delivery of tPA and the perceived benefits accrued to tPA, its use has been limited. Mechanical thrombectomy, a far superior therapy for the largest and most disabling strokes, large vessel occlusions (LVOs), has changed the way acute strokes are managed.
