Background: Reverse shoulder arthroplasty (RSA) is increasingly being utilized for the treatment of primary osteoarthritis. However, limited data are available regarding the outcomes of RSA as compared with anatomic total shoulder arthroplasty (TSA) in the setting of osteoarthritis., Methods: We performed a retrospective matched-cohort study of patients who had undergone TSA and RSA for the treatment of primary osteoarthritis and who had a minimum of 2 years of follow-up. Patients were propensity score-matched by age, sex, body mass index (BMI), preoperative American Shoulder and Elbow Surgeons (ASES) score, preoperative active forward elevation, and Walch glenoid morphology. Baseline patient demographics and clinical outcomes, including active range of motion, ASES score, Single Assessment Numerical Evaluation (SANE), and visual analog scale (VAS) for pain, were collected. Clinical and radiographic complications were evaluated., Results: One hundred and thirty-four patients (67 patients per group) were included; the mean duration of follow-up (and standard deviation) was 30 ± 10.7 months. No significant differences were found between the TSA and RSA groups in terms of the baseline or final VAS pain score (p = 0.99 and p = 0.99, respectively), ASES scores (p = 0.99 and p = 0.49, respectively), or SANE scores (p = 0.22 and p = 0.73, respectively). TSA was associated with significantly better postoperative active forward elevation (149° ± 13° versus 142° ± 15°; p = 0.003), external rotation (63° ± 14° versus 57° ± 18°; p = 0.02), and internal rotation (≥L3) (68.7% versus 37.3%; p < 0.001); however, there were only significant baseline-to-postoperative improvements in internal rotation (gain of ≥4 levels in 53.7% versus 31.3%; p = 0.009). The overall complication rate was 4.5% (6 of 134), with no significant difference between TSA and RSA (p = 0.99). Radiolucent lines were observed in association with 14.9% of TSAs, with no gross glenoid loosening. One TSA (1.5%) was revised to RSA for the treatment of a rotator cuff tear. No loosening or revision was encountered in the RSA group., Conclusions: When performed for the treatment of osteoarthritis, TSA and RSA resulted in similar short-term patient-reported outcomes, with better postoperative range of motion after TSA. Longer follow-up is needed to determine the ultimate value of RSA in the setting of osteoarthritis., Level of Evidence: Therapeutic Level III .

➤: Muscle tendon transfers (MTTs) are effective surgical procedures for reducing pain and for improving active shoulder range of motion and patient-reported outcomes for a wide range of pathologies, including serratus anterior and trapezius muscle palsy, irreparable subscapularis tears, irreparable posterosuperior rotator cuff tears, irreparable posterior rotator cuff tears in the setting of reverse shoulder arthroplasty, and symptomatic complete deltoid deficiency., ➤: The principles of MTT include ensuring that the transferred muscle is expendable, the muscle tendon unit has similar excursion, the line of pull of the transferred tendon and of the recipient muscle are similar in terms of biomechanical force, and the transferred muscle should replace at least 1 grade of strength of the deficient recipient muscle., ➤: When MTT procedures are considered, patients must have exhausted all nonoperative management, have preserved passive range of motion, and have an understanding of the postoperative expectations and potential complications., ➤: For patients with scapulothoracic abnormal motion (STAM) due to long thoracic nerve palsy, the indirect or direct pectoralis major tendon transfer is an effective procedure for reducing pain and improving active forward elevation. For patients with STAM due to spinal accessory nerve palsy, the Eden-Lange or the triple tendon transfer procedures reduce pain and improve active forward elevation and abduction as well as patient-reported clinical outcomes., ➤: Both pectoralis major and latissimus dorsi transfer procedures for isolated irreparable subscapularis deficiency without anterosuperior humeral head escape result in improvement with respect to pain, patient-reported outcomes, and forward elevation, with the pectoralis major tendon transfer demonstrating durable long-term outcomes., ➤: The latissimus dorsi or lower trapezius tendon transfer procedures for irreparable posterosuperior rotator cuff tears reliably improve patient-reported outcomes, forward elevation, abduction, and external rotation range of motion. Additionally, latissimus dorsi transfer with or without teres major transfer can be used to restore active external rotation, both in the native shoulder and in the setting of reverse shoulder arthroplasty., ➤: The complications of MTTs include infection, hematoma, and failure of tendon transfer healing; therefore, it is recommended that these complex procedures be performed by shoulder surgeons with appropriate training., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJS/G956)., (Copyright © 2022 by The Journal of Bone and Joint Surgery, Incorporated.)

Background: As payment models shift toward a focus on value, an accurate understanding of surgical costs and preoperative correlates of high-cost patients is important for effective implementation of cost-saving strategies. This study used time-driven activity-based costing (TDABC) to explore inpatient cost of total shoulder arthroplasty (TSA) and to identify preoperative characteristics of high-cost patients., Methods: Using TDABC, we calculated the cost of inpatient care for 415 patients undergoing elective primary TSA between 2016 and 2017. Patients in the top decile of cost were defined as high-cost patients. Multivariable logistic regression modeling was employed to determine preoperative characteristics (e.g., demographics, comorbidities, American Society of Anesthesiologists [ASA] score, and American Shoulder and Elbow Surgeons [ASES] score) associated with high-cost patients., Results: Implant purchase price was the main driver (57%) of total inpatient costs, followed by personnel cost from patient check-in through the time in the operating room (20%). There was a 1.3-fold variation in total cost between patients in the 90th percentile for cost and those in the 10th percentile; the widest cost variation was in personnel cost from the post-anesthesia care unit through discharge (2.5-fold) and in medication cost (2.4-fold). High-cost patients were more likely to be women and chronic opioid users and to have diabetes, depression, an ASA score of ≥3, a higher body mass index (BMI), and a lower preoperative ASES score than non-high-cost patients. After multivariable adjustment, the 3 predictors of high-cost patients were female sex, an ASA score of ≥3, and a lower ASES score. Total inpatient cost correlated strongly with the length of the hospital stay but did not correlate with operative time., Conclusions: Our study provides actionable data to contain costs in the perioperative TSA setting. From the hospital's perspective, efforts to reduce implant purchase prices may translate into rapid substantial cost savings. At the patient level, multidisciplinary initiatives aimed at reducing length of stay and controlling medication expenses for patients at risk for high cost (e.g., infirm women with poor preoperative shoulder function) may prove effective in narrowing the existing patient-to-patient variation in costs., Level of Evidence: Economic and Decision Analysis Level IV.

Background: There has been little documentation of the effects of total shoulder arthroplasty (TSA) on psychological status and health-related quality of life (HRQoL). We investigated changes in psychological status (depression and anxiety) and HRQoL following TSA and assessed the effect of preoperative psychological status on postoperative clinical and functional outcome. We hypothesized that TSA would improve both psychological status and HRQoL., Methods: We prospectively enrolled 46 patients undergoing TSA for osteoarthritis. Preoperatively and at 3, 6, and 12 months postoperatively, all of the subjects completed the visual analog scale (VAS) for pain, the American Shoulder and Elbow Surgeons Scale (ASES), the Subjective Shoulder Value (SSV) measure, the Hospital Anxiety and Depression Scale (HADS), and the World Health Organization Quality of Life Scale Abbreviated Version (WHOQOL-BREF)., Results: From 3 months after surgery, significant improvement in HADS-depression, HADS-anxiety, and WHOQOL-BREF scores as well as in the other outcome measures of VAS pain score, ASES score, and SSV were observed. The prevalence of depression and anxiety decreased from a rate of 15.2% and 19.5%, respectively, preoperatively to a rate of 6.5% for each at 12 months postoperatively. Preoperative HADS-depression and HADS-anxiety scores did not correlate with any of the clinical and functional outcome measures at 12 months after surgery., Conclusions: This study showed significant improvement in psychological status and HRQoL as well as in pain and functional ability from 3 months after TSA in patients with osteoarthritis. Preoperative depression and anxiety did not predict poor postoperative outcome. Our findings suggest that TSA offers an excellent chance of improving psychological status and HRQoL., Level of Evidence: Therapeutic Level IV.
