TL;DR: Whereas the majority of RSAs are performed for rotator cuff tear arthropathy, one quarter of proximal humerus fractures are treated with RSA, suggesting the strong uptake of this relatively new procedure in the United States.

TL;DR: This study demonstrates the reliability and precision of preoperative planning software and patient-specific guides for glenoid component placement in total shoulder arthroplasty with use of patient- specific templates created by preoperative surgical planning and 3D modeling.

TL;DR: TSA and RTSA have similar complication rates, need for revision, patient-reported outcomes, and range of motion at 2 years of follow-up.

TL;DR: Increasing incidence of shoulder arthroplasty and a constant infection rate will result in greater overall PJI burden, and certain identifiable patient variables correlate with higher PJI rates.

TL;DR: The biomechanics of reverse total shoulder arthroplasty are discussed with a focus on elements of implant design and surgical technique that may affect stability, postoperative complications, and functional outcomes.

TL;DR: The functional and radiologic results of the stemless shoulder arthroplasty are comparable to the third and fourth generation of standard stem arthroPLasty.

TL;DR: The purpose of this article was to review treatment options and clinical outcomes for the management of massive rotator cuff tears.

TL;DR: Improvements can be expected in patients with a history of preoperatively opioid use; however, patients with preoperative opioid use have a lower preoperative baseline and should not expect to reach the same peak outcome scores after RSA as patients without aHistory of preoperative opioids use.

TL;DR: Synovial fluid α-defensin was more effective than current diagnostic testing in predicting positive cultures and may be an effective adjunct in the workup of shoulder PJI.

TL;DR: In the population of patients with degenerative rotator cuff tears who were randomly treated by surgery or conservative protocol, there were no differences in functional outcome as measured with the Constant-Murley score 1 year after treatment, but significant differences in pain and disabilities were observed in favor of surgical treatment.

TL;DR: Pat-specific targeting guides were more accurate than traditional instrumentation and had fewer instances of component malposition for glenoid component placement in this multi-surgeon cadaver study of arthritic shoulders.

TL;DR: The measurement properties of the PROMIS PF CAT compared favorably with the ASES and SST despite requiring fewer questions to complete, and had improved person reliability compared withThe ASES score and fewer floor effects compared with the SST.

TL;DR: Whereas TSA has low short-term rates of perioperative complications and mortality, careful peri operative medical optimization and efficient surgical technique should be emphasized to decrease morbidity and mortality.

TL;DR: Young age, high preoperative function, and neurologic dysfunction were associated with poor functional improvement after reverse shoulder arthroplasty, and surgeons should consider these associations in counseling and selection of patients.

TL;DR: A systematic review of 38 studies and 2222 shoulders found that the rate of scapular nothing was significantly higher with the 155° prosthesis than with the 135° prosthetic with a lateralized glenosphere, with no difference in dislocation rates between prostheses.

TL;DR: The CSA was most susceptible to malposition in anteversion/retroversion, and a new classification system was developed to identify malpositioned radiographs of the scapula.

TL;DR: The frequency of scapular notching was significantly higher in the standard RSA group than in the BIO-RSA cohort, and no other outcome measures were statistically different, including range of motion, strength, and validated outcome scores.

TL;DR: RSA with bony lateralization shows a trend toward improved external rotation in lateralized RSA, with a statistically significant improvement in internal rotation in patients with an intact teres minor.

TL;DR: The greatest risk factors for infection after RSA were history of a prior failed arthroplasty and age younger than 65 years, which is the first study evaluating risk factors after RSA while controlling for confounding variables with multivariable analysis.

TL;DR: Preseason ROM differences were able to identify those adolescents at high risk for injury during the season, and it appears that the risk profile for adolescent pitchers includes horizontal adduction differences that differ from the established prospective profile in adult pitchers.

TL;DR: The use of PRP Therapy in full-thickness rotator cuff repairs showed no statistically significant difference compared with no PRP therapy in clinical outcome scores, but the failure-to-heal rate was significantly decreased when PRP was used for treatment of small- to-moderately sized tears.

TL;DR: A lower threshold for surgical intervention may be considered in proximal-third, two-part spiral-oblique humeral shaft fractures, to establish whether a particular fracture type is more likely to go on to nonunion.

TL;DR: RSA using the shoulder technique described in this series provides good clinical and radiologic outcomes in elderly patients with 3-part and 4-part fractures.

TL;DR: Percutaneous ultrasonic tenotomy performed under local anesthesia appears to be a safe and effective treatment option for chronic, refractory lateral or medial elbow tendinopathy up to 1 year after the procedure.

TL;DR: Patient-level factors associated with prolonged length of stay common to patients undergoing ATSA or RTSA included increasing age, female sex, congestive heart failure, renal failure, chronic pulmonary disease, and preoperative anemia.

TL;DR: At long-term follow-up, both HA and TSA continue to provide lasting pain relief and improved range of motion, however, there are a large number of unsatisfactory Neer ratings.

TL;DR: The rate of posterior and combined instability in an active population is more common than has been previously reported, making up more than 40% of operatively treated instability, including a previously unreported incidence of 19% for combined instabilities.

TL;DR: Investigating the effects of glenosphere diameter on joint load, load angle, and total deltoid force required for active abduction and range of motion in internal/external rotation and abduction found increases in joint load and del toid force were significantly increased.

TL;DR: Patients and surgeons should keep in mind that iatrogenic transient dysfunction of the radial nerve will occur in approximately 1 in 5 patients treated with lateral exposure of the humerus, in 1 in 9 patientstreated with posterior exposure, and in 2 in 25 patients with an anterolateral exposure.

TL;DR: The open Latarjet procedure is effective in treating anterior shoulder instability with marked glenoid bone loss and the incidence of the graft resorption at 1 year postoperatively is high, indicating good interobserver and intraobserver reliability.
