Major exclusion criteria included previous surgery to the affected knee or concomitant injuries to the posterior cruciate ligament and collateral ligaments. The data presented in this study are available on request from the corresponding author due to the data being part of a restricted nationwide insurance dataset. Additional research must be conducted to elucidate the temporal relationship between TRT dosing and surgical outcomes. Regardless, these results may assist shoulder surgeons when evaluating patients on TRT who also seek treatment for degenerative osteoarthritis, differing degrees of rotator cuff arthropathy, or severe forms of impingement. Tests of maximal extensor strength were performed on the participants’ affected and unaffected legs using a NORM dynamometer (Cybex) following the standard protocol for concentric extension at a speed of 60 deg/s.20,34 Patients were positioned on an adjustable chair and secured to the equipment and were instructed to perform 5 concentric leg extensions with 30 seconds of rest in between. Lean mass was measured by whole-body dual-energy x-ray absorptiometry using the Lunar iDXA system (General Electric Healthcare).44,46 Lean body mass was measured to the nearest one-tenth of a kilogram (kg), and previous studies evaluating the precision of the Lunar iDXA system have demonstrated a coefficient of variation 40 Patients were evaluated 2 weeks before surgery, 1 day before surgery, and 6, 12, and 24 weeks after surgery. Comparison of complications after reverse total shoulder arthroplasty (RSA) in testosterone replacement therapy (TRT) cohort and matched control cohort. Comparison of patient demographics of testosterone replacement therapy (TRT) cohort and matched control cohort. There were a total of 1906 patients who used TRT within 90 days of undergoing RSA and at least 2 years of follow-up after surgery. Patient demographics, comorbidities, and surgical complications were compared between the RSA group and the control group to determine if TRT use within 90 days of surgery has any effect on the surgical outcomes. For the present study, patients who were on TRT within 90 days of undergoing RSA were included (1906 patients). Univariate analysis using chi-squared tests and Student’s t-tests were used to compare demographics outcomes between groups. The current literature is inconclusive on the association between TRT and orthopedic surgery. Increasing population age, medical benefits, and public awareness of TRT have resulted in increased prevalence of its utilization. Testosterone replacement therapy (TRT) is an indicated treatment of several medical conditions including late-onset hypogonadism, congenital syndromes, and gender affirmation hormonal therapy. English-language studies, human studies, Level I or II randomized controlled trials, and studies examining testosterone supplementation given during the perioperative period of an orthopaedic surgery were included. Checking for changes in your bone density is the best way to catch osteoporosis before it causes a fracture. A bone density test uses low levels of X-rays to measure how much calcium and other minerals are in your bones. A healthcare provider will diagnose osteoporosis with a bone density test. If you have osteoporosis, you lose bone mass faster than usual. This means your bone density is lower than it should be for your age. While not statistically significant, in the present study, the TRT group had lower rates of periprosthetic fracture after surgery compared to the control group (0.58% vs. 1.05%, respectively). Bone mineral density is one aspect of orthopedic care that has previously shown to be influenced by TRT, as testosterone’s metabolites have a direct impact on osteoblast differentiation . Several clinical studies have investigated the potential risks in association with the cardiovascular , respiratory , urologic , reproductive , and hematologic systems . In the present study, a total of 1906 patients who used TRT within 90 days of RSA were identified from a national insurance claims database. However, this does not take into account patients who never took the actual testosterone. The database infers that patients were on testosterone from a prescription that was filled. While bone–implant integration is a critical aspect of RSA success, this study was unable to account for uncemented vs. cemented implants. Acnes on the epidermis of patients, as testosterone has previously shown to increase this . They’ll tell you how often you’ll need follow-up bone density tests. Your provider might suggest weight-bearing exercise to strengthen your muscles and train your balance. Staying active can strengthen your bones. The most important part of treating osteoporosis is preventing broken bones. Providers sometimes refer to bone density tests as DEXA scans, DXA scans or bone density scans. People in postmenopause lose bone mass even faster. This causes a gradual loss of bone mass. With an increasing population over 65 years of age, the number of men who experience age-related androgen decline will also increase . Testosterone replacement therapy (TRT) has become more prevalent in recent decades for both hypogonadism and gender-affirming care 8,9. As RSA approaches its 20-year anniversary in the United States, implant survivorship has been increasingly studied, with a focus on implant design and placement and patient selection. While historically performed in older populations, the use of RSA in patients younger than 65 is increasing and has been shown to remain safe and effective in appropriately selected cases, contributing to the sharp rise in the number of surgeries performed . These results can assist surgeons when evaluating patients on TRT who also may be candidates for RSA.
