Glenoid loosening, primarily induced by the “rocking horse” phenomenon from humeral head load on the glenoid rim, is the foremost complication and cause of failure in anatomic total shoulder arthroplasty. The dynamic load exerted by universal fatigue testing machines significantly deviates from the standard ASTM F2028-14 in the rocking test. To accurately conduct the in vitro loosening test on anatomic glenoids, a specialized system and customized test methods are developed to achieve anatomic glenoid rocking and subluxation tests. The horizontal and vertical loading can be achieved synchronously or asynchronously by two self-developed high-performance electromagnetic linear motors. In addition, the subluxation tests on anatomic glenoids are verified by finite element simulation. The results show that the subluxation load and translation of anatomic glenoids in the subluxation tests are consistent with those in numerical simulations. The error of the applied axial force in the rocking tests is only 5[Formula: see text]N, strictly meeting the standard of ASTM F2028-14. During the rocking tests, the system runs smoothly and the software works well, indicating the feasibility of the in vitro shoulder joint test system. This study provides an approach to accurate dynamic evaluation of glenoid loosening or disassociation.

Purpose: Although the hematologic benefits of tranexamic acid (TXA) have been thoroughly evaluated, an additional value demonstrated in knee arthroplasty and rotator cuff repair is improved early postoperative range of motion (ROM). This study aims to evaluate whether TXA given during total shoulder arthroplasty (TSA) confers improved early postoperative ROM or pain. Methods: We did retrospective review of 653 TSAs (223 anatomic TSA [aTSA] and 430 reverse TSA [rTSA]) performed in 596 patients at a single institution from 2007 to 2022. Intraoperative TXA use was implemented on a case-by-case basis starting in 2014 then became standard practice in 2016. Pre- to postoperative improvement in ROM was evaluated at 6 weeks, 3 months, 6 months, 1 year, and 2-years of follow-up. Mixed-effects models were used to evaluate whether administration of TXA intraoperatively improved ROM or pain at each follow-up time point. Results: TXA was administered to 26% (n = 58) of aTSAs and 43% (n = 179) of rTSAs. Patients with a history of hypertension received TXA at a higher rate for both aTSA (P = 0.009) and rTSA (P = 0.005). Intraoperative TXA was not associated with improved ROM or pain for aTSA or rTSA at any time point investigated. Average estimated intraoperative blood loss was markedly less in the TXA group for both aTSA [250 to 300 mL] (P < 0.001) and rTSA [200 to 300 mL] (P < 0.001) when compared with the non-TXA groups [300 to 400 mL for both]. Conclusion: Intraoperative TXA does not improve ROM or pain after TSA. However, intraoperative blood loss was reduced, further supporting the routine use of TXA to reduce hematologic complications and improve intraoperative visibility.
