Article Abstract
Background: Glenoid component positioning is an important and challenging aspect of total shoulder arthroplasty. The use of freehand technique with standard instrumentation or preoperative planning based on 2-dimensional computed tomography (CT) scans provides an opportunity for improvement in terms of component accuracy, precision, and deformity correction. These techniques have produced varying outcomes.
Methods: Preoperative planning software (PPS), patient specific instrumentation (PSI), and intraoperative navigation (NAV) have been developed to improve the accuracy of implant placement and deformity correction with the ultimate goals of improved patient outcomes and implant longevity. Literature search was conducted on published and available studies comparing the accuracy of glenoid component placement and improvements in surgical and patient outcomes amongst the aforementioned techniques.
Results: PPS, PSI, and NAV have demonstrated improved accuracy over freehand techniques with standard instrumentation. However, data demonstrating the clinical benefit and cost effectiveness of these new technologies are lacking.
Discussion: In this paper, we reviewed the evidence available to answer the question of whether or not advanced shoulder arthroplasty technologies have been beneficial and reviewed future technologies in development such as virtual/mixed-reality and robotic assisted shoulder surgery.
Level Of Evidence: 4.

Background: Total shoulder arthroplasty frequently is performed in patients with a history of shoulder surgery. The purpose of this study was to evaluate clinical outcomes after primary shoulder arthroplasty in patients with a history of nonarthroplasty shoulder surgery, and whether certain modifiable risk factors (MRFs) were negatively associated with final outcome measures. The secondary purpose was to determine if costs or complications were higher in patients with prior shoulder surgery.

Background: Identification of high-impact chronic pain (HICP) among patients receiving total shoulder arthroplasty (TSA) may allow for the design and implementation of tailored pain interventions to address the negative impact on postoperative outcomes and quality of life. This analysis sought to determine if Patient-Reported Outcome Measurement Information System (PROMIS) measures could be used to estimate HICP status following TSA.
Methods: This was a secondary analysis of a cohort of patients (n = 227) who received a TSA at a single, academic medical center, of whom 25 (11.
Cortical windows for implant and cement removal during revision total elbow arthroplasty.

Division of Hand and Upper-Extremity Surgery, Department of Orthopaedic Surgery, Geisinger Commonwealth School of Medicine, Geisinger MSKI, Danville, PA, USA.
Background: Revision total elbow arthroplasty (rTEA) remains a technically challenging procedure with potential for substantial morbidity. Cases involving excessively long cement mantles, removal of well-fixed implants or infected revisions requiring complete cement removal introduce additional technical challenges. Our purpose was to describe the outcomes, results, and complications associated with the use of cortical windows in rTEA.

Methods: A database of over 10,000 scapulae utilized for preoperative planning for shoulder arthroplasty was analyzed with a Statistical Shape Model to obtain 5 scapula sizes including the mean and 2 standard deviations. For each scapula model, one glenosphere size (33-42 mm) was selected as the best fit based on consensus among 3 shoulder surgeons.
Does morbid obesity negatively impact perioperative outcomes following elective reverse shoulder arthroplasty?: a propensity-matched comparative study.

Department of Orthopaedic Surgery, Montefiore Medical Center, Albert Einstein College of Medicine, Bronx, NY, USA.
Background: The incidence of primary reverse total shoulder arthroplasty (rTSA) and the prevalence of obesity have increased in the United States. Despite this, the literature assessing the effect of morbid obesity (body mass index≥40 kg/m) on perioperative surgical outcomes remains inconsistent.
Methods: A retrospective review of consecutive elective primary rTSA cases from January 2016 through September 2023 at a single tertiary referral center was performed.
