Background: The use of computer assisted surgery, navigation (NAV) in shoulder arthroplasty is still under discussion, regarding the clinical outcome and prosthesis longevity, especially when combining these factors with cost, time and surgeon's experience. Beside the NAV, there has been in use patient-specific instrumentation (PSI) as an additional tool for more precise glenoid implant position. Surgical NAV and PSI for glenoid implant positioning in anatomic and reverse total shoulder arthroplasty are in last years under observation and discussion.
Objective: To critically review and evaluate the current literature regarding the use of computer navigation and PSI in shoulder arthroplasty.
Methods: Critical review of the existing literature.
Results: Cost-effectiveness, prosthesis longevity and revision arthroplasty rate have not yet been proven clinically. Moreover, heterogeneity is high in studies that include different positioning systems (NAV, PSI and standard instrumentation). Heterogeneity is due to differences in surgical technique, implants, surgeon's expertise, radiographic image analysis technique.
Conclusion: The use of navigation systems and PSI should be clinically proven in the shoulder arthroplasty. Independent experts' opinion and independent high level studies lack at the moment. There will be still a lot of talk regarding this topic in future.

Tranexamic acid use in rotator cuff repair: A systematic review of perioperative outcomes.
J Orthop

Department of Orthopaedic Surgery, St. Luke's University Health Network, Bethlehem, PA, USA.
Background: Tranexamic acid (TXA) use has become the gold standard in total joint arthroplasty to limit intraoperative blood loss and transfusion rates. More recently, the indications for TXA have expanded to knee and shoulder arthroscopy with promising early results. However, the effectiveness of TXA during arthroscopic rotator cuff repair (RCR) is unclear.

Purpose: To summarize complication rates, reoperation rates, length-of-stay (LOS), patient-reported outcome measures (PROMs), and range of motion following total shoulder arthroplasty (TSA) in patients with preexisting psychiatric disorders (PDs) compared to controls.
Methods: Three databases (MEDLINE, PubMed, and EMBASE) were searched from inception to 4 March 2024 to identify studies comparing outcomes between patients undergoing anatomic (aTSA) or reverse TSA (rTSA) with or without a preexisting psychiatric condition. The authors adhered to the preferred reporting items for systematic reviews and meta-analyses and revised assessment of multiple systematic review guidelines.
Outcomes after revision surgery for glenoid baseplate failure in reverse shoulder arthroplasty.
Shoulder Elbow
January 2025
Rothman Orthopaedic Institute, Thomas Jefferson University Hospital, Philadelphia, PA, USA.
Background: The purpose of this study was to report clinical outcomes in patients who underwent revision surgery for glenoid baseplate failure after index reverse shoulder arthroplasty (RSA).
Methods: A retrospective review was performed to identify patients from 2010 to 2020 at a single institution who sustained glenoid baseplate failure after RSA and underwent revision surgery. Exclusion criteria included periprosthetic joint infection or lack of minimum 1 year clinical and radiographic follow-up.

Department of Orthopaedic Surgery, Cedars-Sinai Medical Center, Los Angeles, CA, USA.
Background: Poor sleep quality due to nocturnal pain is increasingly reported as a major symptom in several shoulder pathologies. Sleep disturbance has been reported in up to 89% after rotator cuff tears and is frequently reported as the primary reason for referring patients to surgery. As a result, it is important to understand the impact of shoulder surgery on a patient's sleep quality.

Introduction: The humeral head is the second most common site for osteonecrosis but its epidemiology is poorly described. This study aimed to better understand its treatment in the United States by 1) evaluating total operative procedures with rates normalized to the annual surgical volume; 2) determining trends of non-joint preserving (shoulder arthroplasty) vs. joint preserving procedures; and 3) quantifying rates of operative techniques in different aged cohorts (<50 vs.
