Testosterone Replacement Therapy is Not Associated with Greater Revision Rates in Reverse Total Shoulder Arthroplasty
Journal of clinical medicine（2025）
Abstract
Background/Objectives: Testosterone replacement therapy (TRT) has become increasingly common, particularly for patients with symptomatic hypogonadism or individuals undergoing gender-affirming therapy. The current literature is inconclusive on the association between TRT and orthopedic surgery. This study sought to examine outcomes of reverse total shoulder arthroplasty (RSA) in patients receiving TRT. Methods: A retrospective cohort of RSA patients from 2010 to 2022 was queried using the PearlDiver database. Patients were included if they underwent RSA with at least 2 years of follow-up. Patients who underwent at least 90 days of TRT prior to their surgery were matched by Charlson Comorbidity Index, age, and gender to a control cohort. Univariate analysis using chi-squared tests and Student’s t-tests were used to compare demographics outcomes between groups. Results: A total of 1906 patients were identified who used TRT within 90 days of undergoing RSA, and these patients were matched to a control cohort of 1906 patients. Patients who used TRT within 90 days did not have significantly different rates of revision RSA (12.01%) compared to those without use (11.02%) (p = 0.335). Furthermore, between the TRT group and the control group, PJI rates (1.42% vs. 1.63%; p = 0.597) and periprosthetic fracture rates (0.58% vs. 1.05%, p = 0.105) were not significantly different. Conclusions: This study demonstrated that TRT use within 90 days of RSA does not increase the rates of revision, fracture, or infection. These results can assist surgeons when evaluating patients on TRT who also may be candidates for RSA.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
