RESUMEN
CONTEXT: Fastpitch softball is one of the most popular sports in the United States among young female athletes. Softball players regularly subject their shoulders to extreme range of motion and high velocity movements. To date, no systematic review has reported on the epidemiology and incidence of shoulder injuries in softball players. OBJECTIVE: To describe the incidence and epidemiology of softball-related shoulder injuries in youth, high school, and collegiate female softball players. DATA SOURCES: PubMed, Web of Science, and Embase were searched for relevant English language articles from 1980 to 2023. STUDY SELECTION: Studies selected based on predefined inclusion criteria. Studies were required to be available full text, in English. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 4. DATA EXTRACTION: A preliminary screening was performed based on study title and abstract. In the subsequent screening, the full text versions of the remaining articles were evaluated by 2 reviewers for the fulfillment of the inclusion criteria. RESULTS: A total of 7 articles met criteria for inclusion. All studies evaluated injuries among softball players for at least 1 season. In total, there were 1107 softball-related shoulder injuries reported in the 7 studies included in this systematic review. Of the 3 studies that included a shoulder injury rate, a mean rate of 4.01 shoulder injuries per 10,000 athlete-exposures was calculated. The 2 most common shoulder injuries were shoulder muscle-tendon strains (297) and shoulder/biceps tendinitis (220). CONCLUSION: High-level prospective studies reporting injury incidence and risk factors among female softball players are extremely limited. Only 2 studies eligible for inclusion in this systematic review were prospective in nature, with neither of these reporting the specific injury rate for shoulder injuries among softball players.
RESUMEN
BACKGROUND: Management of patients with recurrent anterior glenohumeral instability in the setting of subcritical glenoid bone loss (GBL), defined in this study as 20% GBL or less, remains controversial. This study aimed to compare arthroscopic Bankart with remplissage (ABR+R) to open Latarjet for subcritical GBL in primary or revision procedures. We hypothesized that ABR+R would yield higher rates of recurrent instability and reoperation compared to Latarjet in both primary and revision settings. METHODS: A retrospective study was conducted on patients undergoing either arthroscopic ABR+R or an open Latarjet procedure. Patients with connective tissue disorders, critical GBL (>20%), < 2 year follow-up, or insufficient data were excluded. Recurrent instability and revision were the primary outcomes of interest. Additional outcomes of interest included subjective shoulder value (SSV), strength and range of motion (ROM) RESULTS: 108 patients (70 ABR+R, 38 Latarjet) were included with an average follow-up of 4.3 ±2.1 years. In the primary and revision settings, similar rates of recurrent instability (Primary: p=0.60; Revision: p=0.28) and reoperation (Primary: p=0.06; Revision: p=1.00) were observed between Latarjet and ABR+R. Primary ABR+R exhibited better SSV, active ROM, and internal rotation strength compared to primary open Latarjet. However, no differences were observed in the revision setting. CONCLUSION: Similar rates of recurrent instability and reoperation in addition to comparable outcomes with no differences in ROM were found for ABR+R and Latarjet in patients with subcritical GBL in both the primary and revision settings. ABR+R can be a safe and effective procedure in appropriately selected patients with less than 20% GBL for both primary and revision stabilization.
RESUMEN
Studies have shown that glenoid- and humeral-sided bone loss may be present in up to 73-93% of individuals with recurrent anterior shoulder instability. As such, bone loss must be addressed appropriately, as the amount of bone loss drives surgical decision making and influences outcomes. Methods to describe and measure bone loss have changed over time. Originally, glenoid and humeral bone loss were viewed separately. However, the concepts of bipolar bone loss, the glenoid track (GT), and "on/off-track" lesions arose, highlighting the interplay between the two entities in contributing to recurrent instability. Classically, "off-track" lesions have been described as those Hill-Sachs interval (HSI) greater than the GT, and have been shown to result in higher rates of re-instability when addressed nonoperatively or with Bankart repair alone. More recently, further attention has been given to "on-track" lesions (HSI < GT). The new concept of "distance to dislocation" (DTD) has gained popularity. DTD is calculated as the difference between the GT and HSI, and literature evaluating DTD suggests that not all "on-track" lesions should be treated in the same manner. The purpose of this concept review article is twofold: (I) describe glenoid, humeral, and bipolar bone loss in the setting of anterior shoulder instability; and (II) elaborate on the new concept of "DTD" and its use in guidance of management.
RESUMEN
BACKGROUND: Large, circumferential glenoid labral tears are an uncommon injury affecting young, athletic patients. There are limited data describing the clinical presentation of patients with larger tears, especially 270° and 360° labral tears. Additionally, examination and imaging findings have poor reliability in diagnosing these tears. The purpose of this study was to determine the clinical presentation among patients presenting with small (less than 180°), medium (180°-270°), and large (270°-360°) labral tears. METHODS: This is a retrospective comparative study of consecutive patients surgically managed by a single shoulder surgeon for all glenoid labral tears from 2018-2022. The primary outcome was demographic and preoperative clinical risk factors. Demographic data including age, sex, hand dominance, body mass index, as well as clinical presentation (subluxation vs. dislocation, instability history, and participation in contact sports) were recorded. RESULTS: A total of 188 patients met the inclusion criteria: 101 of 188 (53.70%) patients with small tears, 43 of 188 (22.90%) patients with medium tears, and 44 of 188 (23.40%) patients with large tears. Individuals with large and medium-sized labral tears were more likely to have participated in contact sports compared to those with smaller labral tears (P = .003). Medium and smaller tears were more likely to present as dominant-side injury (P = .02). Furthermore, medium and large tears were more likely to present with anterior instability symptoms compared with smaller tears, which more frequently presented with posterior instability and pain (P = .003). CONCLUSION: Males participating in contact sports were the most common demographic population presenting with large, 270°-360° labral tears. Instability was the primary complaint rather than pain, and compared with small tears, medium and large tears were more likely to present with primary anterior instability. Although arthroscopic repair of 270°-360° labral tears can yield excellent clinical outcomes similar to smaller tears, identifying factors associated with larger glenoid labral tears may help in surgical planning and patient counseling.

BACKGROUND: Margin convergence (MC) and superior capsular reconstruction (SCR) are common treatment options for irreparable rotator cuff tears in younger patients, although they differ in associated costs and operative times. The purpose of this study was to compare range of motion, patient-reported outcomes (PROs), and reoperation rates following MC and SCR. We hypothesized superior outcomes after SCR relative to MC regarding functional outcomes, subjective measures, and reoperation rates. METHODS: This was a multicenter retrospective review of 59 patients from 3 surgeons treating irreparable rotator cuff tears with either MC (n = 28) or SCR (n = 31) and minimum 1-year follow-up from 2014-2019. Visual analog scale (VAS) for pain, Subjective Shoulder Value (SSV), active forward flexion (FF), external rotation (ER), retear rate, and conversion rate to reverse shoulder arthroplasty were evaluated. t tests and χ2 tests were used for continuous and categorical variables, respectively (P < .05). RESULTS: Baseline demographics, range of motion, and magnetic resonance imaging findings were similar between groups. Average follow-up was 31.5 months and 17.8 months for the MC and SCR groups, respectively (P < .001). The MC and SCR groups had similar postoperative FF (151° ± 26° vs. 142° ± 38°; P = .325) and ER (48° ± 12° vs. 46° ± 11°; P = .284), with both groups not improving significantly from their preoperative baselines. However, both cohorts demonstrated significant improvements in VAS score (MC: 7.3 to 2.5; SCR: 6.4 to 1.0) and SSV (MC: 54% to 82%; SCR: 38% to 87%). There were no significant differences in postoperative VAS scores, SSV, and rates of retear or rates of conversion to arthroplasty between the MC and SCR groups. In patients with preoperative pseudoparesis (FF < 90°), SCR (n = 9) resulted in greater postoperative FF than MC (n = 5) (141° ± 38° vs. 67° ± 24°; P = .002). CONCLUSION: Both MC and SCR demonstrated excellent postoperative outcomes in the setting of massive irreparable rotator cuff tear, with significant improvements in PROs and no significant differences in range of motion. Specifically for patients with preoperative pseudoparesis, SCR was more effective in restoring forward elevation. Further long-term studies are needed to compare outcomes and establish appropriate indications.

Objectives: Synovial fluid or tissue culture is the current gold standard for diagnosis of infection, but Cutibacterium acnes (C. acnes) is a frequent cause of shoulder PJI and is a notoriously fastidious organism. The purpose of this study was to compare quantitative real-time polymerase chain reaction (qRT-PCR) to standard culture as a more rapid, sensitive means of identifying C. acnes from the glenohumeral joint. We hypothesized that qRT-PCR would be more effective than standard culture at identifying C. acnes and would have greater sensitivity and specificity for detecting infection. Methods: This was a prospective observational study with 100 consecutive patients undergoing arthroscopic or open shoulder surgery with known positive and negative controls. Intraoperatively, synovial fluid and tissue was obtained for C. acnes qRT-PCR and results were blinded to the gold standard microbiology cultures. Results: Clinical review demonstrated 3 patients (3%) with positive cultures, none of which were positive for C. acnes. Of the samples tested by the C. acnes qRT-PCR standard curve, 12.2% of tissue samples and 4.5% of fluid samples were positive. Culture sensitivity was 60.0%, specificity was 100.0%, PPV was 100.0%, and NPV was 97.9%. C. acnes qRT-PCR standard curve sensitivity, specificity, PPV, and NPV was 60.0%, 90.3%, 25.0%, and 97.7% respectively for tissue specimens and 0%, 95.2%, 0%, and 95.2% respectively, for fluid specimens. For combination of culture and tissue qRT-PCR, the sensitivity, specificity, PPV and NPV was 100%, 90.3%, 35.7%, and 100%, respectively. Conclusion: We report that qRT-PCR for C. acnes identified the organism more frequently than conventional culture. While these findings demonstrate the potential utility of qRT-PCR, the likelihood of false positive results of qRT-PCR should be considered. Thus, qRT-PCR may be useful as an adjuvant to current gold standard workup of synovial fluid or tissue culture for the diagnosis of infection.
RESUMEN
PURPOSE: To determine the comparative accuracy and precision of routine magnetic resonance imaging (MRI) versus magnetic resonance (MR) arthrogram in measuring labral tear size as a function of time from a shoulder dislocation. METHODS: We retrospectively evaluated consecutive patients who underwent primary arthroscopic stabilization between 2012 and 2021 in a single academic center. All patients completed a preoperative MRI or MR arthrogram of the shoulder within 60 days of injury and subsequently underwent arthroscopic repair within 6 months of imaging. Intraoperative labral tear size and location were used as standards for comparison. Three musculoskeletal radiologists independently interpreted tear extent using a clock-face convention. Accuracy and precision of MR labral tear measurements were defined based on location and size of the tear, respectively. Accuracy and precision were compared between MRI and MR arthrogram as a function of time from dislocation. RESULTS: In total, 32 MRIs and 65 MR arthrograms (total n = 97) were assessed. Multivariate analysis demonstrated that intraoperative tear size, early imaging, and arthrogram status were associated with increased MR accuracy and precision (P < .05). Ordering surgeons preferred arthrogram for delayed imaging (P = .018). For routine MRI, error in accuracy increased by 3.4° per day and error in precision increased by 2.3° per day (P < .001) from time of injury. MR arthrogram, however, was not temporally influenced. Significant loss of accuracy and precision of MRI compared with MR arthrogram occurred at 2 weeks after an acute shoulder dislocation. CONCLUSIONS: Compared with MR arthrogram, conventional MRI demonstrates time-dependent loss of accuracy and precision in determining shoulder labral tear extent after dislocation, with statistical divergence occurring at 2 weeks. LEVEL OF EVIDENCE: Level II, retrospective radiographic diagnostic study.
RESUMEN
OBJECTIVE: The purpose of this study was to assess the use of a criteria-based return to sport (CBRTS) test to evaluate readiness for return to play (RTP) in competitive athletes that underwent open Latarjet. DESIGN: Retrospective case series. METHODS: Ten competitive athletes (mean age 19.9 years) treated with open Latarjet for recurrent glenohumeral instability underwent CBRTS testing at a mean of 5.3 months postoperatively. Testing consisted of four components: 1. isometric strength, 2. isokinetic strength, 3. endurance, and 4. function. Patients failing 0 or 1 component of the test were cleared to RTP. Patients failing multiple components underwent additional deficit-based rehabilitation. RESULTS: Of the 10 patients that tested, 4 passed their overall CBRTS test and were cleared to RTP. The remaining 6 patients failed the overall CBRTS test. Seven patients (70%) failed at least one section of the strength testing, two patients (20%) failed endurance testing, and two patients (20%) failed functional testing. At final follow-up (mean 3.6 years), 1 patient had recurrent instability (10%) and 9 patients returned to play (90%). CONCLUSIONS: CBRTS testing may be clinically useful for return to play clearance decisions after open Latarjet procedure, as it can reveal deficits that may not be identified with time-based clearance alone.

BACKGROUND: The primary purpose of this study was to identify demographic, anatomic, and radiographic risk factors for active forward elevation (AFE) <90° in the setting of massive, irreparable rotator cuff tear (miRCT). The secondary purpose was to identify characteristics differentiating between patients with pseudoparalysis (AFE <45°) and pseudoparesis (AFE >45° but <90°). METHODS: This was a retrospective case-control study reviewing patients with miRCTs at a single institution between January 12, 2016 and November 26, 2020. Patients were separated into 2 cohorts based on presence or absence of preoperative AFE <90° with maintained passive range of motion. Demographics, RCT pattern, and radiographic parameters were assessed as risk factors for AFE <90°. A secondary analysis was conducted to compare patients with pseudoparalysis and pseudoparesis. RESULTS: There were 79 patients in the AFE <90° cohort and 50 patients in the control cohort. Univariate analysis confirmed significant differences between the AFE <90° and control cohort in age (71.9 ± 11.0 vs. 65.9 ± 9.1 years), arthritis severity (34.2% vs. 16.0% grade 3 Samilson-Prieto), acromiohumeral distance (AHD; 4.8 ± 2.7 vs. 7.6 ± 2.6 mm), fatty infiltration of the supraspinatus (3.3 ± 0.9 vs. 2.8 ± 0.8) and subscapularis (2.0 ± 1.2 vs. 1.5 ± 1.0), and proportion of subscapularis tears (55.7% vs. 34.0%). On multivariate analysis, age (odds ratio [OR] 1.08, P = .014), decreased AHD (OR 0.67, P < .001), severe arthritis (OR 2.84, P = .041), and subscapularis tear (OR 6.29, P = .015) were independent factors predictive of AFE <90°. Secondary analysis revealed tobacco use (OR 3.54, P = .026) and grade 4 fatty infiltration of the supraspinatus (OR 2.22, P = .015) and subscapularis (OR 3.12, P = .042) as significant predictors for pseudoparalysis compared to pseudoparesis. CONCLUSIONS: In patients with miRCT, increased age, decreased AHD, severe arthritis, and subscapularis tear are associated with AFE <90°. Furthermore, patients with AFE <90° tend to have greater supraspinatus and subscapularis fatty infiltration. Lastly, among patients with AFE <90°, tobacco use and grade 4 fatty infiltration of the supraspinatus and subscapularis are associated with pseudoparalysis compared with pseudoparesis.

Posterior shoulder instability is of particular therapeutic interest, as it typically affects patients with high functional demands such as young athletes and active adults. Although posterior capsulolabral repair has high return-to-sport rates, it is associated with recurrent instability of up to 11%. Posterior glenoid bone loss and significant glenoid retroversion have been identified as risk factors for recurrent instability and failure after primary arthroscopic soft-tissue repair. Therefore, posterior glenoid bone block reconstruction may be indicated for glenoid bone loss 20% or greater (as measured by the perfect circle technique) or greater than 10% in the setting of pathologic glenoid, failed primary posterior labral repair, incompetent posterior capsular tissue, or significant risk factors for failure of soft-tissue repair. This procedure may be performed arthroscopically or with a posterior open approach using distal tibial allograft, iliac crest autograft, or scapular spine autograft. Although short-term to midterm outcomes have been promising, there remain concerns regarding long-term outcomes, with potentially high rates of late recurrence, revision, and secondary osteoarthritis.

INTRODUCTION: Recent studies have defined pseudoparesis as limited active forward elevation between 45° and 90° and maintained passive range of motion (ROM) in the setting of a massive rotator cuff tear (RCT). Although pseudoparesis can be reliably reversed with reverse total shoulder arthroplasty (RSA) or superior capsular reconstruction (SCR), the optimal treatment for this indication remains unknown. The purpose of this study was to compare the clinical outcomes of RSA to SCR in patients with pseudoparesis secondary to massive, irreparable RCT (miRCT). METHODS: This was a retrospective cohort study of consecutive patients aged 40-70 years with pseudoparesis secondary to miRCT who were treated with either RSA or SCR by a single fellowship-trained shoulder surgeon from 2016 to 2021 with a minimum 12-month follow-up. Multivariate linear regression modeling was used to compare active ROM, visual analog pain scale (VAS), Subjective Shoulder Value (SSV), and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score between RSA and SCR while controlling for confounding variables. RESULTS: Twenty-seven patients were included in the RSA cohort and 23 patients were included in the SCR cohort with similar mean follow-up times (26.2 ± 21.1 vs. 21.9 ± 14.7 months, respectively). The patients in the RSA group were significantly older than those in the SCR group (65.2 ± 4.4 vs. 54.2 ± 7.8 years, P < .001) and had more severe arthritis (1.8 ± 0.9 vs. 1.2 ± 0.5 Samilson-Prieto, P = .019). The pseudoparesis reversal rate among the RSA and SCR cohorts was 96.3% and 91.3%, respectively. On univariate analysis, the RSA cohort demonstrated significantly greater mean improvement in active FF (89° ± 26° vs. 73° ± 30° change, P = .048), greater postoperative SSV (91 ± 8% vs. 69 ± 25%, P < .001), lower postoperative VAS pain scores (0.6 ± 1.2 vs. 2.2 ± 2.9, P = .020), and less postoperative internal rotation (IR; 4.6° ± 1.6° vs. 6.9° ± 1.8°, P = .004) compared with SCR. On multivariate analysis controlling for age and osteoarthritis, RSA remained a significant predictor of greater SSV (ß = 21.5, P = .021) and lower VAS scores (ß = -1.4, P = .037), whereas SCR was predictive of greater IR ROM (ß = 3.0, P = .043). CONCLUSION: Although both RSA and SCR effectively reverse pseudoparesis, patients with RSA have higher SSV and lower pain scores but less IR after controlling for age and osteoarthritis. The results of this study may inform surgical decision making for patients who are suitable candidates for either procedure.

BACKGROUND: Recent studies have highlighted dual plating as a method of reducing high rates of postoperative complication after operative management of displaced midshaft clavicular fractures. However, few studies have reliably characterized reoperation rates and magnitude of risk reduction achieved when using dual versus anterior and superior single-plate techniques. HYPOTHESIS: There would be lower rates of reoperation among patients who underwent open reduction and internal fixation (ORIF) of displaced midshaft clavicular fractures via dual plating. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: This was a retrospective analysis of patients who underwent ORIF for a displaced midshaft clavicular fracture between 2010 and 2021 at a level 1 trauma center with a minimum 12-month follow-up. Patients were separated into 3 cohorts based on fixation type: (1) orthogonal dual mini-fragment plate fixation, (2) superior plate fixation, and (3) anterior plate fixation. Data on patient characteristics, fracture pattern, and reoperations were documented. All-cause reoperation rates and hazard ratio (HR) estimates of dual, superior, and anterior plating were calculated using a multivariate multilevel mixed-effects parametric survival model. Significant confounders including high-risk fracture morphology and smoking status were controlled for in the final model. RESULTS: A final cohort of 256 patients was identified with mean follow-up of 4.9 ± 3.8 years. In total, 101 patients underwent superior plating, 92 underwent anterior plating, and 63 underwent dual plating. Overall, 31 reoperations took place (18 in superior, 12 in anterior, 1 in dual plating) among 22 patients. Major contributors to reoperation included symptomatic hardware (n = 11), nonunion (n = 8), deep infection (n = 7), and wound dehiscence (n = 2). Superior plating revealed the highest reoperation rate of 0.031 per person-years, followed by anterior plating with 0.026 per person-years and dual plating with 0.005 per person-years. Overall, single plating (either anterior or superior placement) had a nearly 8-fold greater risk of reoperation than dual plating (HR, 7.62; 95% CI, 1.02-56.82; P = .048). Further broken down by technique, superior plating had an 8-fold greater risk of reoperation than dual plating (HR, 8.36; 95% CI, 1.10-63.86; P = .041), but anterior plating did not demonstrate a statistically significant difference compared with dual plating (HR, 6.79; 95% CI, 0.87-52.90; P = .068). CONCLUSION: Dual-plate fixation represents an excellent treatment for displaced midshaft clavicular fractures, with low rates of nonunion and reoperation. When compared with single locked superior or anterior plate fixation, dual mini-fragment plate fixation has a nearly 8-fold lower risk of reoperation.

Background: The purpose of this study was to compare recurrent instability and return to play (RTP) in young athletes who underwent clearance to full activity based on a validated return-to-sport (RTS) test to those who underwent time-based clearance following primary posterior labral repair. Methods: This was a retrospective review of athletes with posterior shoulder instability who underwent primary arthroscopic posterior labral repair from 2012 to 2021 with minimum 1-year follow-up. Patients who underwent RTS testing at a minimum of 5 months postoperatively were compared to a historic control cohort of patients who underwent time-based clearance. Results: There were 30 patients in the RTS cohort and 67 patients in the control cohort (mean follow-up 32.1 and 38.6 months, respectively). Of the 30 patients who underwent RTS testing, 11 passed without failing any sections, 10 passed while failing 1 section, and 9 failed the RTS test by failing 2+ sections. No differences were found between the RTS and control cohort in the incidence of recurrent instability (6.7% vs. 9.0%), overall RTP (94.7% vs. 94.3%), RTP at the same level as before injury (84.2% vs. 80.0%), recurrent pain/weakness (23.3% vs. 25.4%), or revision surgery (0% vs. 3.0%), respectively. Discussion: While RTS testing in young athletes after posterior labral repair did not reduce recurrence or improve return to play compared to time-based clearance, two-thirds of athletes who underwent testing failed at least 1 section, indicating some functional deficit. Thus, RTS testing may help guide postoperative rehabilitation following posterior stabilization.
RESUMEN
INTRODUCTION: Indications for reverse total shoulder arthroplasty (RSA) have expanded to include individuals with intact rotator cuffs such as patients with severe glenoid deformity or with concern of future rotator cuff insufficiency. The purpose of this study was to compare outcomes of RSA with an intact rotator cuff to RSA for cuff arthropathy and anatomic total shoulder arthroplasty (TSA). We hypothesized that outcomes of RSA with an intact rotator cuff would be comparable to RSA for cuff arthropathy and TSA but with diminished range of motion (ROM) compared with TSA. MATERIALS AND METHODS: Patients at one institution who underwent RSA and TSA between 2015 and 2020 with minimum 12-month follow-up were identified. RSA with preservation of the rotator cuff (+rcRSA) was compared to RSA for cuff arthropathy (-rcRSA) and anatomic TSA (TSA). Demographics and glenoid version/inclination were obtained. Pre- and postoperative ROM; patient-reported outcomes including visual analog scale (VAS), Subjective Shoulder Value (SSV), and American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores; and complications were obtained. RESULTS: Twenty-four patients underwent +rcRSA, 69 underwent -rcRSA, and 93 underwent TSA. There were more women in the +rcRSA cohort (75.8%) than in the -rcRSA (37.7%, P = .001) and TSA (37.6%, P = .001) cohorts. Mean age of the +rcRSA cohort (71.1) was greater than that of TSA (66.0, P = .021) but similar to that of -rcRSA (72.4, P = .237). Glenoid retroversion was greater in +rcRSA (18.2°) compared with -rcRSA (10.5°, P = .011) but was similar to TSA (14.7°; P = .244). Postoperatively, there were no differences in VAS or ASES between +rcRSA vs. -rcRSA and +rcRSA vs. TSA. SSV was lower in +rcRSA (83.9) compared with -rcRSA (91.8, P = .021), but was similar to TSA (90.5, P = .073). Similar ROM was achieved in forward flexion, external rotation, and internal rotation at final follow-up between +rcRSA and -rcRSA, but TSA had greater external rotation (44° vs. 38°, P = .041) and internal rotation (6.5° vs. 5.0°, P = .001) compared with +rcRSA. There were no differences in complication rates. DISCUSSION: At short-term follow-up, preservation of the rotator cuff in RSA demonstrated similarly excellent outcomes and low complication rates compared with RSA with a deficient rotator cuff and TSA, except for slightly lower internal and external rotation compared with TSA. Although multiple factors deserve consideration when choosing between RSA and TSA, RSA with preservation of the posterosuperior cuff is a viable treatment option for glenohumeral osteoarthritis, particularly in patients with severe glenoid deformity or those at risk for future rotator cuff insufficiency.

BACKGROUND: With the COVID-19 pandemic placing an increased burden on health care systems, shoulder arthroplasties are more commonly being performed as outpatient procedures. The purpose of this study was to characterize the 90-day episode-of-care complications of consecutive shoulder arthroplasties defaulted for outpatient surgery without using a prior algorithm for patient selection and to assess for their risk factors. We hypothesized that outpatient shoulder arthroplasty would be a safe procedure for all patients, regardless of patient demographics and comorbidities. METHODS: A retrospective review of consecutive patients who underwent planned outpatient anatomic or reverse total shoulder arthroplasty between March 2020 and January 2022 with 3-month follow-up was performed. All patients were scheduled for outpatient surgery regardless of medical comorbidities. Patient demographics; pre/postoperative patient-reported outcomes including visual analog scale, subjective shoulder value, and American Shoulder and Elbow Surgeons score; pre/postoperative range of motion; and complications were collected from medical chart review. Multivariate logistic regression was used to identify predictors of the following outcomes: 1. Unplanned overnight hospital stay, 2. 90-day unplanned emergency department (ED)/clinic visit, 3. 90-day hospital readmission, 4. 90-day complications requiring revision. RESULTS: One hundred twenty-seven patients (47% male, 17% tobacco users, 18% diabetics) with a mean age 69 ± 9 years were identified, of whom 92 underwent reverse total shoulder arthroplasty and 35 underwent anatomic total shoulder arthroplasty. All patient-reported outcomes and range of motion were significantly improved at 3 months. There were 15 unplanned overnight hospital stays (11.8%) after the procedure. Within 90 days postoperatively, there were 17 unplanned ED/clinic visits (13.4%), 7 hospital readmissions (5.5%), and 4 complications requiring revision (3.1%). Factors predictive of unplanned overnight stay included age above 70 years (odds ratio [OR], 36.80 [95% confidence interval [CI], 2.20-615.49]; P = .012), tobacco use (OR, 12.90 [95% CI, 1.23-135.31]; P = .033), and American Society of Anesthesiologists status of 3 (OR, 13.84 [95% CI, 1.22-156.57]; P = .034). The only factor predictive of unplanned ED/clinic visit was age over 70 years old (OR, 7.52 [95% CI, 1.26-45.45]; P = .027). No factors were predictive of 90-day hospital readmission or revision. CONCLUSION: Outpatient shoulder arthroplasty is a safe procedure with excellent outcomes and low rates of readmissions and can be considered as the default plan for all patient undergoing shoulder arthroplasty. Patients who are above 70 years of age, use tobacco, and have ASA score of 3, however, may be less suitable for outpatient arthroplasty and should be counseled regarding the higher risk of unplanned overnight hospitalization.
