Abstract
Background A proposed etiology of anterior shoulder pain and limited internal rotation after reverse shoulder arthroplasty (RSA) is impingement of the humeral component on the coracoid or conjoint tendon. The primary goal of this study was to investigate radiographic surrogates for potential coracoid or conjoint tendon impingement and their relationship to postoperative pain and internal rotation after RSA. Methods A retrospective review of a clinical registry was performed to identify patients with (1) primary RSA, (2) minimum 2-year clinical follow-up, and (3) satisfactory postoperative axillary lateral radiographs. The primary radiographic measurement of interest was the subcoracoid distance (SCD), defined as the distance between the posterior aspect of the coracoid and the anterior glenosphere. Additional measurements were as follows: anterior glenosphere overhang, posterior glenosphere overhang, native glenoid width, lateralization of glenosphere relative to the coracoid tip, lateralization shoulder angle, and distalization shoulder angle. The primary clinical outcome of interest was the 2-year postoperative Visual Analog Scale score. Secondary outcomes were (1) internal rotation (IR) defined by spinal level (IRspine), (2) IR at 90 degrees of abduction, (3) American Shoulder and Elbow Surgeons score, (4) forward flexion, and (5) external rotation at 0 degrees of abduction. Linear regression analyses were used to evaluate the relationship of the various radiographic measures on the clinical outcomes of interest. Results Two hundred seventeen patients were included. There was a statistically significant relationship between the SCD and Visual Analog Scale scores: B = -0.497, P = .047. There was a statistically significant relationship between the SCD and IRspine: B = -1.667, P < .001. Metallic lateralization was also positively associated with improving IRspine; increasing body mass index was negatively associated. There was a statistically significant relationship between the SCD and IR at 90 degrees of abduction: B = 5.844, P = .034. Conclusion For RSA with a 135° neck shaft angle and lateralized glenoid, the postoperative SCD has a significant association with pain and IR. Decreasing SCD was associated with increased pain and decreased IR, indicating that coracoid or conjoint tendon impingement may be an important and potentially under-recognized etiology of pain and decreased IR following RSA. Further investigations aimed toward identifying a critical SCD to improve pain and IR may allow surgeons to preoperatively plan component position to improve clinical outcomes after RSA.

Abstract
BACKGROUND Despite advancements in surgical technique, failure of tendon healing remains a common problem after arthroscopic rotator cuff repair (ARCR). PURPOSE/HYPOTHESIS The purpose of this study was to examine the relationship between range of motion (ROM) recovery and healing after ARCR. It was hypothesized that an early loss of ROM would be associated with tendon healing. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS This was a retrospective comparative study of primary ARCR of isolated full-thickness supraspinatus (SSN) tendon tears. Cases were retrieved from a prospective rotator cuff repair database and divided into 2 groups based on healing (healed/nonhealed). A standardized clinical evaluation was performed before and at 6 weeks, 3 months, and 6 months after surgery. Collected data included passive and active ROM, visual analog scale for pain, and Constant score. Healing was assessed by ultrasound at 6 months. RESULTS Of 1397 eligible ARCRs, 1207 were included. The healing rate was 86.7%. Age was higher in the nonhealed group (57.8 ± 7.9 years vs 61.6 ± 8.8 years; P < .001). Patients with healed repairs had a larger decrease in passive anterior elevation (AE) from the preoperative to the 6-week postoperative visit (-31°± 28° vs -18°± 26°; P < .001), followed by a more substantial increase throughout the remaining follow-up period (32°± 23° vs 18°± 21°; P < .001). At 6 months postoperatively, there was no difference in AE between groups (159°± 17° vs 161°± 14°; P > .999). External rotation elbow at side (ER1) and internal rotation hand in the back (IR1) followed similar courses of recovery. Passive and active ROM had a strong positive correlation at each follow-up. Age (odds ratio [OR], 1.79; 95% CI, 1.45-2.23; P < .001) and 6-week passive AE (OR, 1.33; 95% CI, 1.20-1.48; P < .001) and ER1 (OR, 1.15; 95% CI, 1.03-1.29; P = .017) were predictors for nonhealing. CONCLUSION Lower passive AE and ER1 at 6 weeks postoperatively and younger age are associated with healing after ARCR of isolated SSN tendon tears. At 6 months postoperatively, there were no differences in ROM, regardless of tendon healing.

Abstract
Background Lateralization in reverse shoulder arthroplasty (RSA) decreases bony impingement and improves rotational range of motion, but has been theorized to increase the risk of subacromial notching (SaN). The purpose of this study was to evaluate the presence of SaN following RSA and its relationship with lateralization with a 135° inlay humeral component. The secondary purpose was to assess the association of SaN with functional outcomes. Methods A retrospective review was performed from a multicenter prospectively collected database on patients who underwent primary RSA from 2015 to 2021. All RSAs were performed with a 135° inlay humeral component. SaN was defined as bony erosion with sclerotic margins on the undersurface of the acromion on final follow-up radiographs not present preoperatively. Postoperative implant positioning (inclination, distalization, and lateralization) were evaluated on minimum 1-year postoperative radiographs. Regression analyses were performed on implant and clinical variables to assess for risk factors. A separate analysis was performed to determine the association of SaN with clinical outcomes. Results SaN was identified in 13 out of 442 shoulders (2.9%). Age, sex, body mass index, smoking status, diabetes mellitus, arm dominance had no relationship with SaN. Neither glenoid sided lateralization nor humeral offset were associated with SaN risk. Other implant characteristics such as distalization, glenosphere size, and postoperative inclination did not influence SaN risk. The presence of SaN did not affect patient-reported outcomes (American Shoulder and Elbow Surgeons: P = .357, Visual Analog Scale: P = .210) or range of motion. Conclusion The rate of SaN is low and not associated with glenoid or humeral prosthetic lateralization when using a 135° inlay humeral component. When SaN occurs, it is not associated with functional outcomes or range of motion at short-term follow-up.

Abstract
PURPOSE To evaluate the relation between subscapularis (SSC) Goutallier grade or coracohumeral distance (CHD) and SSC tears, as well as the relation between these radiographic variables and long head of the biceps tendon lesions. METHODS A retrospective analysis was conducted on prospectively maintained data on patients who underwent arthroscopic rotator cuff repair of SSC tears between 2011 and 2021 with at least 6 months of follow-up. Patients with identified subscapularis tears during arthroscopy were included. A control group was established by randomly selecting patients without SSC tears from the same study period. Goutallier grading and CHD were obtained from preoperative magnetic resonance imaging (MRI) scans. Receiver operating characteristic analysis was conducted to define optimal cutoff values for these diagnostic measures. RESULTS The study included 735 patients with SSC tears and 249 patients in the control group. Comparing subscapularis tear and intact groups' Goutallier grades revealed significant differences in infraspinatus, upper and lower SSC, and overall SSC (P < .001). No significant difference was detected in supraspinatus Goutallier grade (P = .364). An SSC tear was observed in 58.3% (n = 265) of patients with Goutallier grade 0 of the upper SSC, 77.1% (n = 195) of patients with grade 1 changes, 98.7% (n = 155) with grade 2 changes, and 100% of grade 3 or 4 changes. Goutallier grade of the upper SSC showed a significant correlation with tear size (rs = 0.533; P < .01). CHD measurements were lower in individuals with SSC tears compared to those without tears (6.6 ± 1.7 vs 9.6 ± 1.8; P < .001). Upper SSC Goutallier grade >1 had an acceptable area under the curve (AUC) of 0.742. CHD of 7.96 mm or less had an excellent predictive AUC of 0.879. CONCLUSIONS Higher Goutallier grade and CHD narrowing are potential associations predictive of SSC tears. Routine MRI assessment of muscle of the upper SSC and the CHD can contribute to the diagnostic accuracy of SSC tears and offer valuable information regarding the severity of such tears. LEVEL OF EVIDENCE Level III, diagnostic study.

Abstract
Background Minimal Clinically Important Difference (MCID) and Patient-Acceptable Symptomatic State (PASS) have emerged as patient-based treatment assessments. However, these have not been investigated in patients undergoing arthroscopic isolated subscapularis repair (AISR). The primary purpose of this study was to determine the MCID and PASS for commonly used patient-reported outcomes in individuals who underwent AISR. The secondary purpose was to assess potential associations between preoperative and intraoperative patient characteristics and the MCID and PASS. Methods A retrospective analysis was conducted on prospectively collected data for patients who underwent primary AISR between 2011 and 2021 at a single institution, with minimum 2-year postoperative follow-up. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), and Visual Analog Scale (VAS) pain scale. The MCID was determined using the distribution-based method, while PASS was evaluated using area under the curve analysis. To investigate the relationship between preoperative variables and the achievement of MCID and PASS thresholds, Pearson and Spearman coefficient analyses were employed for continuous and noncontinuous variables, respectively. Results A total of 77 patients with a mean follow-up of 58.1 months were included in the study. The calculated MCID values for VAS pain, ASES, and SSV were 1.2, 10.2, and 13.2, respectively. The PASS values for VAS pain, ASES, and SSV were 2.1, 68.8, and 68, respectively. There was no significant correlation between tear characteristics and the likelihood of achieving a MCID or PASS. Female sex, worker's compensation status, baseline VAS pain score, and baseline ASES score, exhibited weak negative correlations for achieving PASS for VAS pain and ASES. Conclusion This study defined the MCID and PASS values for commonly used outcome measures at short-term follow-up in patients undergoing AISR. Tear characteristics do not appear to impact the ability to achieve a MCID or PASS after AISR. Female sex, worker's compensation claim, and low baseline functional scores have weak negative correlations with the achievement of PASS for VAS pain and ASES scores.

Abstract
PURPOSE OF REVIEW Massive irreparable rotator cuff tears (MIRCTs) present treatment challenges. Recently, superior capsule reconstruction (SCR) and anterior cable reconstruction have emerged as surgical options, but no single approach is superior. This review provides an overview of SCR and cable reconstruction techniques, including biomechanical studies, clinical outcomes, and surgical considerations. RECENT FINDINGS Biomechanical studies show SCR with autografts or allografts improves glenohumeral stability and mechanics. Clinical outcomes of SCR demonstrate improved range of motion, function scores, and pain relief in short-term studies. Anterior cable reconstruction reduces superior humeral head translation and subacromial pressures in biomechanical models. Early clinical studies report improved rotator cuff healing and outcomes for cable reconstruction in specific irreparable tear patterns. SCR and cable reconstruction are viable surgical options for MIRCTs based on early encouraging results. However, higher-level comparative studies with long-term follow-up are still needed. Careful consideration of tear pattern, patient factors, and surgical goals is required to optimize treatment of MIRCTs. Further research is necessary to determine the optimal role for these procedures.

Abstract
Massive rotator cuff tears are a challenge to treat, with options available from arthroscopic rotator cuff repair to reverse shoulder arthroplasty. Arthroscopic repair may still be an option even in the setting of advanced Goutallier changes and Hamada grades and regardless of healing. As the lifetime risk of revision for a 55-year-old patient having a reverse shoulder arthroplasty is approximately 1 in 3, arthroscopic surgical management of massive rotator cuff tears should not be discounted. An individualized approach should consider the patient's radiographs (severity of arthritis), function (i.e., acute vs chronic pseudoparalysis), and goals (overhead strength vs pain relief). Younger patients with less arthritis, acute pseudoparalysis, and a focus on pain relief could benefit from arthroscopic treatment.

Abstract
IMPORTANCE Reverse shoulder arthroplasty (RSA) is often used to surgically address massive irreparable rotator cuff tears (MIRCT) without arthritis. The impact of prior attempted rotator cuff repair (RCR) on outcomes is unclear. OBJECTIVE The purpose of this systematic review was to compare functional outcomes, range of motion, and complications in patients with a MIRCT without arthritis who underwent RSA as a primary procedure versus after prior RCR. EVIDENCE REVIEW A systematic review was performed on RSA for a MIRCT. The search was conducted from February to March of 2022 using the MEDLINE database. Patient-reported outcome measures (PROs), range of motion (ROM), and complications were extracted. These outcomes were weighted and analysed based on whether the reverse was performed as the primary procedure or following a prior RCR. FINDINGS Seven studies were included in the analysis, consisting of 343 cases in the primary RSA group and 95 cases in the prior RCR group, with a mean follow-up of 40.8 months. There were no demographic differences between cohorts. Postoperative PROs and ROM were comparable between groups, although the prior RCR group had a higher maximal percentage of improvement (MPI%) for the Constant-Murley Score and Simple Shoulder Test. There was a higher risk for complications (relative risk [RR] 6.26) and revisions (RR 3.91) in the prior RCR group. The most common complications were acromial stress fractures and prosthetic dislocation. CONCLUSION AND RELEVANCE Patients undergoing RSA for MIRCT following a prior RCR have functional outcomes that are largely comparable to those who have a primary RSA, but they may be at higher risk of complications and revision.

Abstract
PURPOSE To establish minimal clinically important difference (MCID) and patient acceptable symptomatic state (PASS) values for 4 patient-reported outcomes (PROs) in patients undergoing arthroscopic massive rotator cuff repair (aMRCR): American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), Veterans Rand-12 (VR-12) score, and the visual analog scale (VAS) pain. In addition, our study seeks to determine preoperative factors associated with achieving clinically significant improvement as defined by the MCID and PASS. METHODS A retrospective review at 2 institutions was performed to identify patients undergoing aMRCR with minimum 4-year follow-up. Data collected at the 1-year, 2-year, and 4-year time points included patient characteristics (age, sex, length of follow-up, tobacco use, and workers' compensation status), radiologic parameters (Goutallier fatty infiltration and modified Collin tear pattern), and 4 PRO measures (collected preoperatively and postoperatively): ASES score, SSV, VR-12 score, and VAS pain. The MCID and PASS for each outcome measure were calculated using the distribution-based method and receiver operating characteristic curve analysis, respectively. Pearson and Spearman coefficient analyses were used to determine correlations between preoperative variables and MCID or PASS thresholds. RESULTS A total of 101 patients with a mean follow-up of 64 months were included in the study. The MCID and PASS values at the 4-year follow-up for ASES were 14.5 and 69.4, respectively; for SSV, 13.7 and 81.5; for VR-12, 6.6 and 40.3; and for VAS pain, 1.3 and 1.2. Greater infraspinatus fatty infiltration was associated with failing to reach clinically significant values. CONCLUSIONS This study defined MCID and PASS values for commonly used outcome measures in patients undergoing aMRCR at the 1-year, 2-year, and 4-year follow-up. At mid-term follow-up, greater preoperative rotator cuff disease severity was associated with failure to achieve clinically significant outcomes. LEVEL OF EVIDENCE Level IV, case series.

Abstract
Background Few studies have reported clinical outcomes and tendon healing rates after arthroscopic isolated subscapularis (SSC) repair (AISR). Purpose/Hypothesis The primary purpose of this study was to evaluate clinical outcomes and tendon healing after AISR. It was hypothesized that AISR would result in satisfactory clinical outcomes along with a high rate of tendon healing at the midterm follow-up. The secondary purpose was to assess the influence of tear size and muscle atrophy on SSC tendon healing and patient-reported outcomes. It was hypothesized that both would be negatively correlated with healing but would have no effect on clinical outcomes . Study Design Case series; Level of evidence, 4. Methods A retrospective analysis was conducted on prospectively collected data for 77 patients who underwent primary AISR between 2011 and 2021 at a single institution, with a minimum 2-year postoperative follow-up for all patients. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, the Subjective Shoulder Value (SSV), and the visual analog scale for pain. Repair techniques and concomitant procedures were also collected. SSC tendon healing was evaluated via ultrasound at the final follow-up. Linear regression analysis was performed to determine factors affecting SSC healing. Results The mean follow-up was 58.1 ± 3.3 months. ASES scores significantly improved from 41.5 to 81.6, and the SSV improved from 38.2 to 80.5 (P < .01 for both). Among the 40 patients (51.9%) who underwent postoperative ultrasound, 87.5% showed complete tendon healing. There were no significant differences in outcome scores between healed and unhealed tendons. Increased muscle atrophy and larger tears were correlated with failure of SSC healing (β = -0.285 [P = .015] and β = -0.157 [P = .045], respectively). Conclusion Improved clinical outcomes and an overall high rate of tendon healing were seen at the midterm follow-up after AISR. Smaller tear sizes with less muscle atrophy were correlated with improved tendon healing. However, even when the tendon incompletely healed, the procedure improved functional outcomes.

Abstract
Background Excellent short-term outcomes after reverse shoulder arthroplasty (RSA) have been reported, but longer term outcomes in the existing literature are sparse and vary widely. The purpose of this study is to systematically assess the existing literature to quantify functional outcomes and complication rates after RSA at a minimum of five years of follow-up. Methods A Preferred Reporting Items for Systematic Reviews and Meta-analyses-compliant systematic literature search of the PubMed and Embase databases was undertaken. Studies reporting outcomes after primary RSA for nontrauma-related indications with a minimum of 5-year follow-up were included. Results Overall, 20 studies satisfied all inclusion criteria. This represented 1591 shoulders in 1556 patients (32.1% males), with a mean age of 70.2 ± 5.0 years and mean follow-up of 8.8 years, or 106.2 ± 30.1 months (60-243). At final follow-up, the mean reported Constant Murley score was 62.1 ± 5.0 (49.0-83.0). The mean adjusted Constant Murley score was 83.5 ± 12.5 (58-111.9). The mean American Shoulder and Elbow Surgeons score was 81.8 ± 4.6, while the mean subjective shoulder value was 74.6 ± 6.4. Overall, 88% of patients rated their satisfaction as either good or very good. The range of active forward flexion, abduction, external, and internal rotation were respectively, 126° ± 13°, 106° ± 11°, 22° ± 11°, and 6° ± 2°. The overall rate of revision surgery was 4.9% (0%-45.5%). Regarding complications, the rate of prosthetic joint infection was 4.3% (0%-26.7%), shoulder dislocation was 3.7% (0%-20.4%), and acromial fracture was 2.0% (0%-8.8%). At final follow-up, 30.9% of shoulders had some degree of scapular notching. Conclusion This systematic review shows that RSA results in high satisfaction rates, good clinical outcomes, as well as modest complication and revision rates at minimum 5-year follow-up.

Abstract
PURPOSE To describe and compare the recurrence rates in contact or collision (CC) sports after arthroscopic Bankart repair (ABR) and to compare the recurrence rates in CC versus non-collision athletes after ABR. METHODS We followed a prespecified protocol registered with PROSPERO (registration No. CRD42022299853). In January 2022, a literature search was performed using the electronic databases MEDLINE, Embase, and CENTRAL (Cochrane Central Register of Controlled Trials), as well as clinical trials records. Clinical studies (Level I-IV evidence) that evaluated recurrence after ABR in CC athletes with a minimum follow-up period of 2 years postoperatively were included. We assessed the quality of the studies using the Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) tool, and we described the range of effects using synthesis without meta-analysis and described the certainty of the evidence using GRADE (Grading of Recommendations, Assessment, Development, and Evaluations). RESULTS We identified 35 studies, which included 2,591 athletes. The studies had heterogeneous definitions of recurrence and classifications of sports. The recurrence rates after ABR varied significantly among studies between 3% and 51% (I2 = 84.9%, 35 studies and 2,591 participants). The range was at the higher end for participants younger than 20 years (range, 11%-51%; I2 = 81.7%) compared with older participants (range, 3%-30%; I2 = 54.7%). The recurrence rates also varied by recurrence definition (I2 = 83.3%) and within and across categories of CC sports (I2 = 83.8%). CC athletes had higher recurrence rates than did non-collision athletes (7%-29% vs 0%-14%; I2 = 29.2%; 12 studies with 612 participants). Overall, the risk of bias of all the included studies was determined to be moderate. The certainty of the evidence was low owing to study design (Level III-IV evidence), study limitations, and inconsistency. CONCLUSIONS There was high variability in the recurrence rates reported after ABR according to the different types of CC sports, ranging from 3% to 51%. Moreover, variations in recurrence among CC sports were observed, with ice hockey players being in the upper range but field hockey players being in the lower range. Finally, CC athletes showed higher recurrence rates when compared with non-collision athletes. LEVEL OF EVIDENCE Level IV, systematic review of Level II, III, and IV studies.

Abstract
PURPOSE To analyze the relationship between Area Deprivation Index (ADI) and preoperative status and short-term postoperative clinical outcomes among patients who underwent arthroscopic rotator cuff repair (ARCR) of massive rotator cuff tears (MRCTs). METHODS A retrospective review was conducted on prospectively maintained data on patients who underwent ARCR of MRCTs defined as tear size ≥5 cm or complete tear of at least 2 tendons, with a minimum 2-year follow-up and a valid home address between January 2015 and December 2018. Each patient's home address was mapped to the ADI to determine neighborhood disadvantage. This composite index is composed of 17 census-based indicators, including income, education, employment, and housing quality to quantify the level of socioeconomic deprivation. Ratings were recorded and categorized based on the sample's percentile. Patients were then divided into 2 groups: upper quartile (ie, most disadvantaged [≥75th percentile]) and lower 3 quartiles (ie, least disadvantaged [<75th percentile]). Bivariate analysis was performed to associate ADI with patient-reported outcomes (PROs) and range of motion pre- and postoperatively, as well as complications, healing rate, satisfaction, and return to work. Patients reaching or exceeding the minimal clinically important difference for visual analog scale (VAS), American Shoulder and Elbow Surgeons, Veterans Rand 12-Item questionnaire, and subjective shoulder value were recorded for both cohorts. RESULTS Ninety-nine patients were eligible for study analysis. Preoperative PROs and range of motion were similar, except for a greater VAS for pain (6.3 vs 4.3; P < .01) and lower American Shoulder and Elbow Surgeons score (32.2 vs 45.1; P = .01) in the most disadvantaged group. Both groups showed similar postoperative PROs scores, but greater VAS improvement was seen in the upper quartile group (Δ 4.2 vs Δ 3.0; P = .04). In contrast, only the least-disadvantaged group significantly improved in internal rotation (P = .01) and forward flexion (18°; P < .01) from baseline. Although satisfaction, complications, and return to work were comparable (P > .05), failure of healing occurred more frequently in the most disadvantaged group (21% vs 6%; P = .03). CONCLUSIONS Patients with MRCTs residing in the most disadvantaged neighborhoods as measured by the ADI have more pain and functional limitations before undergoing ARCR but demonstrate similar postoperative functional improvements to patients from other socioeconomic backgrounds. Failure of healing of MRCTs may be more common in disadvantaged groups. Furthermore, both groups reported similar rates of clinically important functional improvement. LEVEL OF EVIDENCE Level III, retrospective cohort comparison.

Abstract
BACKGROUND Glenoid-sided lateralization in reverse shoulder arthroplasty (RSA) decreases bony impingement and improves rotational range of motion, but has been theorized to increase the risk of acromial or scapular spine fractures (ASFs). The purpose of this study was to assess if glenoid-sided lateralization even up to 8 mm increases the risk for stress fracture following RSA with a 135° inlay humeral component. METHODS A retrospective review was performed from a multicenter prospectively collected database on patients who underwent primary RSA from 2015 to 2021. All RSAs were performed with a 135° inlay humeral component. Varying amounts of glenoid lateralization were used from 0 to 8 mm. Preoperative radiographs were reviewed for the presence of acromial thinning, acromiohumeral distance (AHD), and inclination. Postoperative implant position (distalization, lateralization, and inclination) as well as the presence of ASF was evaluated on minimum 1-year postoperative radiographs. Regression analyses were performed on component and clinical variables to assess for factors predictive of ASF. RESULTS Acromial or scapular spine fractures were identified in 26 of 470 shoulders (5.5%). Glenoid-sided lateralization was not associated with ASF risk (P = .890). Furthermore, the incidence of fracture did not vary based on glenoid-sided lateralization (0-2 mm, 7.4%; 4 mm, 5.6%; 6 mm, 4.4%; 8 mm, 6.0%; P > .05 for all comparisons). RSA on the dominant extremity was predictive of fracture (odds ratio [OR] 2.21, 95% confidence interval [CI] 1.20-5.75; P = .037), but there was no relationship between patient age, sex, preoperative acromial thinning, or diagnosis and risk of fracture. Although there was no difference in mean postoperative AHD between groups (P = .443), the pre- to postoperative delta AHD was higher in the stress fracture group (2.0 ± 0.7 cm vs. 1.7 ± 0.7 cm; P = .015). For every centimeter increase in delta AHD, there was a 121% increased risk for fracture (OR 2.21, 95% CI 1.33-3.68; P = .012). Additionally, for every 1-mm increase in inferior glenosphere overhang, there was a 19% increase in fracture risk (P = .025). CONCLUSION Up to 8 mm of glenoid-sided metallic lateralization does not appear to increase the risk of ASF when combined with a 135° inlay humeral implant. Humeral distalization increases the risk of ASF, particularly when there is a larger change between pre- and postoperative AHD or higher inferior glenosphere overhang. In cases of pronounced preoperative superior humeral migration, it may be a consideration to avoid excessive postoperative distalization, but minimizing bony impingement via glenoid-sided lateralization appears to be safe.

Abstract
PURPOSE This study aimed to evaluate whether functional internal rotation (fIR) following reverse shoulder arthroplasty (RSA) differs based on diagnosis of either: primary osteoarthritis (OA) with intact rotator cuff, massive irreparable rotator cuff tear (MICT) or cuff tear arthropathy (CTA). METHODS A retrospective review was carried out on RSAs performed by a single surgeon with the same implant over a 5-year period. Minimum 2-year follow-up was available in 235 patients; 139 (59.1%) were female, and the mean patient age was 72 ± 8 years. Additional clinical evaluation included the Subjective Shoulder Value and Constant score. Postoperative internal rotation was categorized as type I: hand to the buttock or hip; type II: hand to the lower lumbar region; or type III: smooth motion to at least the upper lumbar region. Type I was considered "nonfunctional" internal rotation, and type II and III were fIR. RESULTS Preoperatively, internal rotation was classified as type I in 60 patients (25.5%), type II in 114 (48.5%), and type III in 62 (26%). Postoperatively, internal rotation was classified as type I in 70 patients (30%), type II in 86 (36%), and type III in 79 (34%). Compared with preoperative status, fIR improved significantly in OA patients (P < .001), with 49 (52.6%) classified as type II or III postoperatively. In CTA patients, there was no significant change (P = .352). In patients with MICTs, there was a significant loss in fIR postoperatively (P = .003), with 25 patients (30.8%) deteriorating to type I after having either type II or III preoperatively, and only 5 patients (6.1%) improving to either type II or III. CONCLUSIONS Patients who undergo RSA for primary OA have a better chance of postoperative fIR improvement. A decrease in fIR is common after RSA for MICTs.

Abstract
BACKGROUND Reproducible methods for determining adequate bone densities for stemless anatomic total shoulder arthroplasty (aTSA) are currently lacking. The purpose of this study was to evaluate the utility of preoperative computed tomography (CT) imaging for assessing the bone density of the proximal humerus for supportive differentiation in the decision making for stemless humeral component implantation. It was hypothesized that preoperative 3-dimensional (3-D) CT bone density measures provide objective classifications of the bone quality for stemless aTSA. METHODS A 3-part study was performed that included the analysis of cadaveric humerus CT scans followed by retrospective application to a clinical cohort and classification with a machine learning model. Thirty cadaveric humeri were evaluated with clinical CT and micro-CT (μCT) imaging. Phantom-calibrated CT data were used to extract 3-D regions of interest and defined radiographic scores. The final image processing script was applied retrospectively to a clinical cohort (n = 150) that had a preoperative CT and intraoperative bone density assessment using the "thumb test," followed by placement of an anatomic stemmed or stemless humeral component. Postscan patient-specific calibration was used to improve the functionality and accuracy of the density analysis. A machine learning model (Support vector machine [SVM]) was utilized to improve the classification of bone densities for a stemless humeral component. RESULTS The image processing of clinical CT images demonstrated good to excellent accuracy for cylindrical cancellous bone densities (metaphysis [ICC = 0.986] and epiphysis [ICC = 0.883]). Patient-specific internal calibration significantly reduced biases and unwanted variance compared with standard HU CT scans (P < .0001). The SVM showed optimized prediction accuracy compared with conventional statistics with an accuracy of 73.9% and an AUC of 0.83 based on the intraoperative decision of the surgeon. The SVM model based on density clusters increased the accuracy of the bone quality classification to 87.3% with an AUC of 0.93. CONCLUSIONS Preoperative CT imaging allows accurate evaluation of the bone densities in the proximal humerus. Three-dimensional regions of interest, rescaling using patient-specific calibration, and a machine learning model resulted in good to excellent prediction for objective bone quality classification. This approach may provide an objective tool extending preoperative selection criteria for stemless humeral component implantation.

Abstract
Background The role of obesity as an independent risk factor for increased complications following reverse shoulder arthroplasty (RSA) continues to generate debate. While no standardized body mass index (BMI) cutoff values for shoulder arthroplasty exist, many surgeons are concerned about the potential for poor outcomes and decreased range of motion (ROM) in patients with a high BMI. The purpose of this study was to compare functional outcomes in obese and nonobese patients preoperatively and at short-term follow-up after RSA. Methods A retrospective review was performed of a prospectively maintained, multicenter database of primary RSAs performed by 14 surgeons between 2015 and 2019 with minimum 2-year follow-up. A total of 245 patients met the study criteria, including 111 obese (BMI >30) and 134 nonobese (BMI <30) patients. Patient-reported outcomes (PROs) as well as ROM measurements were compared between the 2 groups. Results At baseline, obese patients had significantly lower American Shoulder and Elbow Surgeons (36.6 vs. 42.0, P = .014), Western Ontario Osteoarthritis of the Shoulder scores (33.1 vs. 37.8, P = .043), external rotation at 90° (19° vs. 28°, P = .007), internal rotation (IR) spinal level (L5 vs. L4, P = .002), and belly press strength (P = .003) compared to the nonobese cohort. There were no statistical differences in 2-year outcomes (PROs, ROM, and strength) other than a worse IR (spinal level) in the low BMI group (L4 vs. L3, P = .002). In linear regression analyses controlling for confounding variables, increasing BMI was negatively correlated with preoperative external rotation (B = -0.591, P = .034) and preoperative IR spinal level (B = 0.089, P = .002). Increasing BMI was not correlated with postoperative external rotation at 90° (B = 0.189, P = .490) but was associated with worse postoperative IR by spinal level (B = 0.066, P = .043). Conclusions Obese patients have greater restrictions in external and internal rotation as well as American Shoulder and Elbow Surgeons and Western Ontario Osteoarthritis of the Shoulder scores at baseline prior to RSA. However, there are no major differences in postoperative PROs or ROM measurements between obese and nonobese patients apart from a worse active IR by spinal level in the obese group (L4 vs. L3, P = .002). This study suggests that an RSA procedure does not need to be restricted solely based on BMI.

Abstract
Background Improvements in pain control after shoulder arthroplasty with a reduction in narcotic use continues to be an important postoperative goal. With the increased utilization of stemless anatomic total shoulder arthroplasty (aTSA), it is relevant to compare between stemmed and stemless arthroplasty to assess if there is any association between this implant design change and early postoperative pain. Methods Patients from a multicenter, prospectively-maintained database who had undergone a stemless aTSA with a minimum of two year clinical follow-up were retrospectively identified. Patients who underwent aTSA with a short stem were identified in the same registry, and matched to the stemless aTSA patients by age, sex and preoperative pain score. The primary study outcome was the Visual Analog Scale pain score. Secondary pain outcomes were the American Shoulder and Elbow Surgeons shoulder pain subscore, Western Ontario Osteoarthritis of the Shoulder physical symptoms subscore, and the Single Assessment Numeric Evaluation score. Finally, the percentage of patients who could sleep on the affected shoulder was assessed for each group. These pain-related clinical outcomes were assessed and compared preoperatively, and postoperatively at 9 weeks, 26 weeks, one year and two years. For all statistical comparisons, P > .05 was considered significant. Results 124 patients were included in the study; 62 in each group. At 9 weeks after surgery, statistically significantly improved pain control was reported by patients undergoing stemless aTSA, as assessed by the Visual Analog Scale (stemless: 1.5, stemmed: 2.5, P = .001), American Shoulder and Elbow Surgeons pain subscore (stemless: 42.4, stemmed: 37.3, P < .001), Western Ontario Osteoarthritis of the Shoulder Physical Symptoms (stemless: 80.3, stemmed: 73.1, P = .006) and Single Assessment Numeric Evaluation (stemless: 58.1, stemmed: 47.4, P = .011). Patients who underwent a stemless aTSA were significantly more likely to be able to sleep on the affected shoulder at 9 weeks (29% vs. 11%, odds ratio 3.2, 95% confidence interval 1.2-8.4, P = .014). By 26 weeks postoperatively, there were no differences in all pain-specific outcomes. At two years postoperatively, patient-reported outcomes, range of motion, and strength measures were all similar between the two cohorts. Conclusion Stemless aTSA provides earlier improvement in postoperative shoulder pain compared to matched patients undergoing short-stem aTSA. Additionally, earlier return to sleeping on the affected shoulder was reported in the stemless aTSA group. The majority of these differences dissipate by 26 weeks postoperatively and there were no differences in pain, patient-reported outcomes, range of motion or strength measures between stemless and short-stem aTSA at 2 years postoperatively.

Abstract
Background Glenohumeral osteophytes (OPs) can adversely influence postoperative range of motion (ROM) following shoulder arthroplasty due to mechanical impingement. Though commercial three-dimensional preoperative planning software (3D PPS) is available to simulate ROM before and after OP resection, little is known about the magnitude of effect OPs and their subsequent removal have on simulated glenohumeral ROM. Methods Included patients were 1) indicated for reverse total shoulder arthroplasty (rTSA) using 3D PPS and 2) presented with glenoid and/or humeral head OPs on preoperative two-dimensional computed tomography (2D-CT) imaging. Thirty patients met the inclusion criteria (9 females, 21 males; mean age 70.45 ± 4.99 years, range 63-80 years). All subjects (n = 30) presented with humeral OPs (mean volume: 2905.16 mm3, range 109.1-11,246 mm3), while 11 subjects also presented with glenoid OPs (mean volume 108.06 mm3, range 37.59-791.4 mm3). Preoperative CTs were used to calculate OP volume (mm3) and OP circumferential extent (clockface). Mean clockface position for circumferential humeral OPs originated at 6:09 (range 4:30-7:15) and extended to 8:51 (range 8:15-10:15). Mean clockface position for glenoid OPs originated at 3:00 (range 2:00-5:00) and extended to 6:16 (range 3:00-7:30). 3D implants on PPS were standardized to achieve 0° of version, 0° of inclination and 4 mm of net lateralization. Thirty-nine and thirty-six mm glenospheres were used for males and females, respectively. 3D PPS was used to evaluate simulated ROM differences before and after OP removal in the planes of adduction (ADD), abduction, internal rotation (IR), external rotation (ER), extension, and flexion. Impact of OP volume and circumferential extent on pre and postop removal ROM were also analyzed. Results Humeral OP removal significantly increased impingement-free ADD, IR, ER, extension, and flexion. Removal of larger (mm3) humeral OPs positively correlated with improvement in IR (R = 0.452, P = .011), ER (R = 0.394, P = .033), and flexion (R = 0.500, P < .01). Greater circumferential extent of humeral OPs correlated with worse preremoval ROM in the planes of ADD (R = 0.364, P = .02) and extension (R = 0.403, P = .04), and improvements in ER postop removal (R = 0.431, P = .03). Conclusion Humeral OP removal significantly increases impingement-free ADD, IR, ER, extension, and flexion in simulated 3D PPS models following rTSA. Magnitude of simulated ROM improvement is influenced by initial humeral OP volume and circumferential clockface extent. Surgeons should consider these effects when using 3D PPS for rTSA planning to optimize postoperative ROM prognostics.

Abstract
BACKGROUND The optimal management of primary glenohumeral arthritis (GHOA) in the elderly is an ongoing topic of debate. The purpose of this study was to compare functional outcomes and complications in patients aged 75 years or older treated with anatomic total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (RSA) for primary GHOA with an intact rotator cuff. METHODS A retrospective study was performed on a prospectively maintained database which was queried for patients 75 years of age or older who underwent TSA or RSA for primary GHOA with an intact rotator cuff at a single institution between 2012 and 2021 with minimum 2-year follow-up. Patient-reported outcomes (PROs), including Visual Analog Scale for pain, American Shoulder and Elbow Surgeons, and Subjective Shoulder Value, as well as active range of motion including forward flexion, external rotation, internal rotation, were collected preoperatively and postoperatively. Complications, reoperations, and satisfaction were also recorded. The percentage of patients achieving clinically significant improvement was evaluated with the minimally clinical important difference, substantial clinical benefit, and patient acceptable symptomatic state for each PRO. RESULTS One-hundred and 4 patients were available for analysis, including 67 TSA patients and 37 RSAs with a mean follow-up of 39.4 months. Preoperative baseline characteristics, PROs, and range of motion were similar between groups. RSA was more commonly performed for eccentric glenoid wear (Walch B2/B3, 62% vs. 22%; P < .001). While clinical outcomes improved comparably in both groups, the TSA cohort showed significantly greater improvement in external rotation (36° vs. 26°; P = .013). Both cohorts had low revision (3% for TSA vs. 0% for RSA) and complication (7% for TSA vs. 5% for RSA; P = .677) rates. Satisfaction was similar in both groups (93% for TSA vs. 92% for RSA; P = .900). Clinically significant improvement was comparable between groups based on the American Shoulder and Elbow Surgeons score (minimally clinical important difference, 93% for TSA vs. 100% for RSA; substantial clinical benefit, 82% vs. 95%; patient acceptable symptomatic state, 67% vs. 78%; P > .05). CONCLUSION In this retrospective small sample size comparison study, TSA and RSA provide similar short-term clinical outcomes for patients 75 years and older with primary GHOA and an intact rotator cuff. Complication and revision rates are comparably low at short-term follow-up. Our data suggests that advanced age alone should not be used as a decision-making tool for TSA vs. RSA in the setting of primary GHOA with an intact rotator cuff.

Abstract
Purpose To report patient-reported outcomes (PROs), range of motion (ROM), and satisfaction, in patients who underwent arthroscopic lysis of adhesions for stiffness after open reduction with internal fixation (ORIF) or reverse shoulder arthroplasty (RSA) for fracture. Methods A retrospective review was performed to identify patients with stiffness who underwent arthroscopic lysis of adhesions following ORIF or RSA for proximal humerus fracture at a single institution between 2012 and 2021 with minimum 1-year follow-up. PROs including visual analog scale for pain (VAS), American Shoulder and Elbow Surgeons (ASES), and Subjective Shoulder Value (SSV), as well as active ROM including forward flexion (FF), external rotation (ER), internal rotation (IR), were collected pre- and postoperatively. Attempted nonoperative treatment before arthroscopic lysis of adhesions was documented. Complications and satisfaction were also recorded. Results A total of 21 patients met the study criteria (4 RSA, 17 ORIF), with an average age of 66.7 ± 8 years. The study sample comprised mostly of female patients (90%). The mean time from the index surgery to arthroscopy was 9 months, and mean follow-up post-lysis was 17 months. Patients with ORIF reported significant pain relief (VAS, Δ -3.2) and improvement in range of motion (FF, Δ 36°; ER, Δ 20°; IR Δ 3 spinal levels) and PROs (ASES, Δ 34.7; SSV Δ 44.8) (P < .01) after lysis. Patients with RSA had significant improvement in ASES (Δ 21.8; P = .04), SSV (Δ 8.8; P = .04), and FF (Δ 38; P = .02) but did not have significant improvement in VAS (Δ -2; P = .2), ER (Δ 0°; P = 1.0), and IR (Δ 1 spinal level; P = .2). Satisfaction was 100% in the RSA cohort and 82% in the ORIF cohort. No complications were observed. Conclusions Arthroscopic lysis of adhesions for stiffness after surgical management of proximal humerus fracture leads to satisfactory outcomes in most patients. Post-ORIF, patients may achieve improvement in PROs and global ROM, whereas post-RSA, patients may achieve improvement in PROs and FF but do not necessarily improve in rotational ROM. Level of Evidence Level IV, therapeutic case series.

Abstract
Subscapularis integrity is critical after anatomic total shoulder arthroplasty, with failure leading to potential instability, loss of function, and revision surgery. The three well-described subscapularis mobilization techniques during total shoulder arthroplasty include tenotomy, peel, and lesser tuberosity osteotomy (LTO). While several comparative studies exist, the optimal approach remains controversial. LTO has been associated with the highest healing rates, but techniques and repair constructs are highly variable. The purpose of this article was to provide an overview of LTO with attention on radiographic assessment, repair options, and clinical outcomes.

Abstract
Advances in the understanding and management of bone loss in shoulder instability have led to the development of free bone block techniques as an alternative to the Latarjet procedure. These techniques have been proposed as a theoretically safer option to Latarjet, and there is growing clinical enthusiasm in their use. The purpose of this article was to contextualize the utilization of free bone block procedures in the current treatment paradigm of anterior shoulder instability and to review the history and common types of bone autograft (eg, iliac crest, distal clavicle, scapular spine) and allograft (eg, distal tibia, preshaped blocks) techniques and approaches, as well as their clinical effectiveness and safety.

Abstract
Background Surgeon visual estimation of shoulder range of motion (ROM) is commonplace in the outpatient office setting and routinely reported in clinical research, but the reliability and accuracy of this practice remain unclear. The purpose of this study is to establish the reliability and accuracy of remote visual estimation of shoulder ROM in healthy volunteers and symptomatic patients among a large group of shoulder surgeons. Our hypothesis is that remote visual estimation would be reliable and accurate compared with the digital goniometer method. Methods Fifty shoulder surgeon members of the PacWest Shoulder and Elbow Society independently determined the active shoulder forward flexion (FF), internal rotation at 90° abduction (IR90), external rotation at 90° abduction, external rotation at the side , and maximal spinal level reached with internal rotation (IRspine) through visual estimation of video recordings taken from 10 healthy volunteers and 10 symptomatic patients. Variations in measurements were quantified using the interobserver reliability through calculation of the intraclass correlation coefficient. Accuracy was determined through comparison with digital goniometer measurements obtained with an on-screen protractor application using Bland-Altman mean differences and 95% limits of agreement. Results The interobserver reliability among examiners showed moderate to excellent correlation, with intraclass correlation coefficient ranging from 0.768 to 0.928 for the healthy volunteers and 0.739 to 0.878 for the symptomatic patients. Accuracy was limited, with upper limits of agreement exceeding the established minimal clinically important differences (MCIDs) for FF (20° vs. MCID of 14°) and IR90 (25° vs. 18°) in the healthy volunteers and for FF (33° vs. 16°), external rotation at 90° abduction (21° vs. 18°), and IR90 (31° vs. 20°) in the symptomatic patients. Conclusion Despite generally high intersurgeon reliability in the visual estimation of shoulder ROM, there was questionable accuracy when compared to digital goniometer measurements,with measurement errors often exceeding established MCID values. Given the potential implications for the clinical response to treatment and the significance of research findings, the adoption of validated instruments to measure ROM and the standardization of examination procedures should be considered.

Abstract
In arthroscopic rotator cuff repair, poor tendon quality, medially based tears, lateral tendon loss, or limited tendon mobility can all preclude the use of double-row suture constructs, presenting a challenge in achieving secure fixation and tendon-to-bone healing. Rip-stop suture configurations can be used in these settings to improve resistance to tissue cutout and provide enhanced biomechanical characteristics compared with standard single-row repairs. The load-sharing rip-stop technique uses 2 double-loaded medial suture anchors, which are placed adjacent to the articular margin, and 1 rip-stop suture tape, which is independently secured to bone with 2 lateral knotless anchors. The load-sharing rip-stop technique has been shown to improve ultimate load to failure by 1.7 times compared with a single-row repair. Clinically, this technique has been associated with a 53% healing rate of large and massive rotator cuff tears, compared with only 11% healing when using single-row repair. A completely knotless variation rip-stop configuration also has been described and shown to be biomechanically equivalent to a single-row repair with triple-loaded anchors. For surgeons desiring a single-row repair only, the knotless rip-stop therefore presents an advantage by eliminating the need for knot-tying and decreasing operative time.

Abstract
Massive rotator cuff tears are one the most challenging conditions to treat in the shoulder. A variety of surgical approaches have been used to manage massive rotator cuff tears, such as repair with or without augmentation, superior capsule reconstruction, tendon transfer, and reverse shoulder arthroplasty. The choice between joint preservation or reverse shoulder arthroplasty is first considered based on preoperative imaging and functional status, as well as patient factors. When joint preservation is the goal of treatment, a combination of repairability, patient function, and age can be used to provide an algorithmic approach to treatment. LEVEL OF EVIDENCE: Level V, expert opinion.

Abstract
BACKGROUND Recent literature has shown the advantages of outpatient surgery for many shoulder and elbow procedures, including cost savings with equivalent safety in appropriately selected patients. Two common settings for outpatient surgeries are ambulatory surgery centers (ASCs), which function as independent financial and administrative entities, or hospital outpatient departments (HOPDs), which are owned and operated by hospital systems. The purpose of this study was to compare shoulder and elbow surgery costs between ASCs and HOPDs. METHODS Publicly available data from 2022 provided by the Centers for Medicare & Medicaid Services (CMS) was accessed via the Medicare Procedure Price Lookup Tool. Current Procedural Terminology (CPT) codes were used to identify shoulder and elbow procedures approved for the outpatient setting by CMS. Procedures were grouped into arthroscopy, fracture, or miscellaneous. Total costs, facility fees, Medicare payments, patient payment (costs not covered by Medicare), and surgeon's fees were extracted. Descriptive statistics were used to calculate means and standard deviations. Cost differences were analyzed using Mann-Whitney U tests. RESULTS Fifty-seven CPT codes were identified. Arthroscopy procedures (n = 16) at ASCs had significantly lower total costs ($2667 ± $989 vs. $4899 ± $1917; P = .009), facility fees ($1974 ± $819 vs. $4206 ± $1753; P = .008), Medicare payments ($2133 ± $791 vs. $3919 ± $1534; P = .009), and patient payments ($533 ± $198 vs. $979 ± $383; P = .009) compared with HOPDs. Fracture procedures (n = 10) at ASCs had lower total costs ($7680 ± $3123 vs. $11,335 ± $3830; P = .049), facility fees ($6851 ± $3033 vs. $10,507 ± $3733; P = .047), and Medicare payments ($6143 ± $2499 vs. $9724 ± $3676; P = .049) compared with HOPDs, although patient payments were not significantly different ($1535 ± $625 vs. $1610 ± $160; P = .449). Miscellaneous procedures (n = 31) at ASCs had lower total costs ($4202 ± $2234 vs. $6985 ± $2917; P < .001), facility fees ($3348 ± $2059 vs. $6132 ± $2736; P < .001), Medicare payments ($3361 ± $1787 vs. $5675 ± $2635; P < .001), and patient payments ($840 ± $447 vs. $1309 ± $350; P < .001) compared with HOPDs. The combined cohort (n = 57) at ASCs had lower total costs ($4381 ± $2703 vs. $7163 ± $3534; P < .001), facility fees ($3577 ± $2570 vs. $6539.1 ± $3391; P < .001), Medicare payments ($3504 ± $2162 vs. $5892 ± $3206; P < .001), and patient payments ($875 ± $540 vs. $1269 ± $393; P < .001) compared with HOPDs. CONCLUSION Shoulder and elbow procedures performed at HOPDs for Medicare recipients were found to have average total cost increase of 164% compared with those performed at ASCs (184% savings for arthroscopy, 148% for fracture, and 166% for miscellaneous). ASC use conferred lower facility fees, patient payments, and Medicare payments. Policy efforts to incentivize migration of surgeries to ASCs may translate into substantial health care cost savings.

Abstract
BACKGROUND Reconstruction techniques for anterior glenoid bone loss have seen a trend from screws to suture-based fixations. However, comparative biomechanical data, including primary fixation and glenoid-graft contact pressure mapping, are limited. HYPOTHESIS Suture-based bone block cerclage (BBC) and suspensory suture button (SB) techniques provide similar primary fixation and cyclic stability to double-screw fixation but with higher contact loading at the bony interface. STUDY DESIGN Controlled laboratory study. METHODS In total, 60 cadaveric scapulae were prepared to simulate anterior glenoid bone loss with coracoid autograft reconstruction. Graft fixation was performed with 3 different techniques: (1) an interconnected all-suture BBC, (2) 2 SB suspensions, and (3) 2 screws. Initial compression was analyzed during primary fixation. Cyclic peak loading with 50 N and 100 N over 250 cycles at 1 Hz was performed with a constant valley load of 25 N. Optical recording and pressure foils allowed for spatial bone block tracking and contact pressure mapping at the glenoid-graft interface. Load-to-failure testing was performed at a rate of 1.5 mm/s with ultimate load and stiffness measured. RESULTS Initial graft compression was higher with screw fixation (141 ± 5 N) compared with suture-based fixations (P < .001), with BBC fixation providing significantly higher compression than SB fixation (116 ± 7 N vs. 91 ± 5 N; P < .001). Spatial bone block migration and ultimate failure load were similar between the BBC and screw groups. The SB group showed significantly increased bone block translation (3.1 ± 1.0 mm; P≤ .014) and rotation (2.5°± 1.4°; P≤ .025) and significantly lower ultimate failure load (180 ± 53 N) compared with the BBC (P = .046) and screw (P = .002) groups. Both suture-based fixations provided significantly increased graft-glenoid contact loading with higher pressure amplitudes (P≤ .032) and contact pressure after cyclic loading (+13%; SB: P = .007; BBC: P = .004) compared with screw fixation. CONCLUSION Both SB and interconnected cerclage fixation improved dynamic contact loading compared with screw fixation in a biomechanical glenoid bone loss model. Cerclage fixation was biomechanically comparable with screw fixation but with a greater variability. SB fixation showed significantly lower primary fixation strength and greater bone block rotation and migration. CLINICAL RELEVANCE Suture-based bone block fixations improved graft-glenoid contact loading, but the overall clinical consequence on healing remains unclear.

Abstract
» Secondary rotator cuff insufficiency is a challenging complication after anatomic total shoulder arthroplasty.» Acute tears may be amenable to open or arthroscopic repair in some instances.» Chronic attritional tears are best managed with revision to reverse shoulder arthroplasty, especially in the elderly.» Increased glenoid inclination, larger critical shoulder angle, oversized humeral components, thicker glenoid components, and rotator cuff muscle fatty infiltration have all shown to contribute to tear risk.

Abstract
Background Short stems have become increasingly popular in reverse shoulder arthroplasty (RSA) due to their ability to preserve bone stock for revision surgery. However, short stems may be more at risk for malalignment or loosening, and commercially available stems have varied designs. The purpose of this study was to perform a multiplanar analysis of proximal humerus anatomy in patients with rotator cuff arthropathy to better define canal geometry and identify differences based on sex. Methods A retrospective review was performed of a consecutive series of patients undergoing RSA for rotator cuff arthropathy. A total of 117 patients were identified with preoperative computed tomography scans. Measurements were undertaken following multiplanar reconstruction of the computed tomography scans. Measured parameters included the following: transition point (TP), anteroposterior (AP) and mediolateral (ML) distances, intramedullary (IM) and bone diameter, and cortical thickness. The TP was defined as the distance from the periosteal border of the greater tuberosity to the level of the IM canal where the endosteal borders became parallel. Measurements started at the metaphysis, and then proceeded 25 and 50 mm distal to the metaphysis followed by 10 mm increments thereafter. Each level was compared to the level above with t tests in the overall cohort and separately by sex. Height was correlated to ML-AP difference and IM diameter with Pearson correlation coefficient. Potential stem sizes that extended 50, 60, 70, and 80 mm from the metaphysis were analyzed to record the percentage of patients in whom the stem would reach past the TP. Results The mean TP for all patients was 55.6 ± 7.4 mm (37.5-78.4) from the greater tuberosity, 53.3 ± 6.6 mm (37.5-67.0) in females and 58.1 ± 7.5 mm (41.9-78.4) in males. ML and AP distances and IM diameter became consistent at level 3 (mean, 83 mm distal to the greater tuberosity) in the overall cohort and in both sexes. Height positively correlated with IM diameter. Males had significantly larger IM diameters compared to females at all levels. Cortical thickness remained relatively consistent throughout the proximal humerus. A stem length of 70 mm would extend past the TP in 98% of patients. Conclusion Humeral implants in RSA with a stem of at least 70 mm in length would extend distally past the TP in the majority of cases regardless of sex. At this point, the canal's area remains consistent which would facilitate diaphyseal fixation if required.

Abstract
Background Different patient-reported outcome (PRO) tools are used in patients with arthroscopic rotator cuff repair (ARCR) which complicates outcome comparisons. The purpose of this systematic review was to compare PRO usage and baseline scores across world regions and countries in patients with ARCR of massive rotator cuff tears (MRCT). Methods A systematic review was performed on ARCR for MRCT. The search was conducted from September to November of 2022 using the MEDLINE database for articles published in the last 15 years. Thirty-seven articles were included after initial screening and full-text review. In each article, PRO usage, baseline scores, and country of origin were collected. PRO usage was reported in percentages and baseline scores were normalized for each region to facilitate comparisons. Normalization was performed using the PRO means from each article. These averages were converted to fractions using the worst and best possible scores. These were combined into a single numerical value, expressed as a decimal from 0 to 1, using the total sample size for each tool per region. Values closer to 0 represent worse functional outcomes. Results Thirty-two percent (n = 12) of articles were from Asia, 43.2% (n = 16) from Europe, 5.4% (n = 2) from the Middle East, and 18.9% (n = 7) from North America. The most commonly reported PRO tools were American Shoulder and Elbow Surgeons (ASES) in 19 papers, Constant-Murley Score (CMS) in 26 papers, Visual Analog Scale for pain (VAS) in 19 papers, and University of California in Los Angeles (UCLA) in 11 papers. ASES was reported in 51% of articles with 63% being from Asia (n = 12) compared to 21% from North America (n = 4). CMS was reported in 70% of studies with 58% being from Europe. Upon normalization, the preoperative score ranged from 0.30 to 0.44. Europe (0.39), and North America (0.40) showed similar scores. The lowest and highest scores were seen in the Middle East (0.3) and Asia (0.44) respectively. Conclusion There is no standardized method to report outcomes in patients undergoing ARCR for MRCT. Great variation in usage exists in PROs which complicates data comparison between world regions. With normalization, baseline scores where similar among Asia, North America, and Europe, and lowest in the Middle East.

Abstract
Purpose To assess functional outcomes and healing 4 years after arthroscopic repair of massive rotator cuff tears (MRCTs). Methods We conducted a retrospective study of patients who underwent arthroscopic rotator cuff repair of an MRCT-defined as a complete 2-tendon tear or a tear greater than 5 cm in any dimension-performed by 2 surgeons at different institutions between January 2015 and December 2018. At a minimum of 4 years postoperatively, patient-reported outcomes collected included the visual analog scale pain score, American Shoulder and Elbow Surgeons (ASES) score, Veterans RAND 12 (VR-12) score, and Subjective Shoulder Value (SSV) score. Repair technique and concomitant procedures were also gathered. Tendon healing was evaluated via ultrasound at final follow-up. Results Functional outcomes were available for 101 patients at a mean of 63.6 ± 8.8 months (range, 48-82 months) postoperatively. Mean ASES scores improved from 40.1 to 78 (P < .001); VR-12 scores, from 37.1 to 47.7 (P < .001); and SSV scores, from 36.7 to 84.6 (P < .001). Forward flexion improved from 126° to 144° (P = .001), external rotation remained unchanged (from 47° to 44°, P = .268), and internal rotation improved by 2 spinal levels (from L4 to L2, P = .0001). Eighty-eight percent of patients (89 of 101) were satisfied with the procedure, and only 5% underwent reverse shoulder arthroplasty within the study period. Among the 39 patients who underwent postoperative ultrasound to assess healing, 56% showed complete tendon healing. There was no difference in healing or outcomes according to tear pattern. Additionally, tendon healing did not affect outcomes. Conclusions Arthroscopic repair of MRCTs leads to functional improvements and patient satisfaction in most cases at 4-year follow-up. The rates of patients achieving the minimal clinically important difference were 77.5%, 87.6%, 59.7%, and 80.6% for the ASES score, SSV score, VR-12 score, and visual analog scale pain score, respectively. Complete tendon healing is difficult to achieve but does not appear to limit functional improvements. Level of Evidence Level IV, therapeutic case series.

Abstract
Purpose To evaluate patient satisfaction at a minimum of 4 years after arthroscopic rotator cuff repair (ARCR) of massive rotator cuff tears (MRCT), to identify preoperative and intraoperative characteristics associated with satisfaction, and to compare clinical outcomes between satisfied and dissatisfied patients. Methods A retrospective review on prospectively collected data was conducted on ARCRs of MRCTs performed at 2 institutions between January 2015 and December 2018. Patients with a minimum 4-year follow-up, preoperative and postoperative data, and primary ARCR of MRCTs were included for analysis. Patient satisfaction was analyzed according to patient demographics, patient-reported outcome measures (American Shoulder and Elbow Surgeons score [ASES], visual analog scale [VAS] for pain, Veteran Rands 12-item health survey [VR-12], and Subjective Shoulder Value [SSV]), range of motion (forward flexion [FF], external rotation [ER], and internal rotation [IR]), tear characteristics (fatty infiltration, tendon involvement, and tear size), and clinical significant measures (minimal clinical important difference [MCID], substantial clinical benefit [SCB], and patient-acceptable symptomatic state [PASS]) for ASES and SSV. Rotator cuff healing was also assessed with ultrasound in 38 patients at final follow-up. Results A total of 100 patients met the study's criteria. Overall, 89% of patients were satisfied with ARCR of a MRCT. Female sex (P = .007) and increased preoperative infraspinatus fatty infiltration (P = .005) were negatively associated with satisfaction. Those in the dissatisfied cohort had significantly lower postoperative ASES (80.7 vs 55.7; P = .002), VR-12 (49 vs 37.1; P = .002), and SSV scores (88.1 vs 56; P = .003), higher VAS pain (1.1 vs 4.1; P = .002) and lower postoperative range of motion in FF (147° vs 117°; P = .04), ER (46° vs 26°; P = .003), and IR (L2 vs L4; P = .04). Rotator cuff healing did not have an influence on patient satisfaction (P = .306). Satisfied patients were more likely to return to work than dissatisfied patients (97% vs 55%; P < .001). Conclusions Nearly 90% of patients who undergo ARCR for MRCTs are satisfied at a minimum 4-year follow-up. Negative preoperative factors include female sex and increased preoperative infraspinatus fatty infiltration, but no association was observed with rotator cuff healing. Furthermore, dissatisfied patients were less likely to report a clinically important functional improvement. Level of Evidence Level IV, prognostic case series.

Abstract
BACKGROUND Preoperative assessment of the glenoid and surgical placement of the initial guide wire are important in implant positioning during reverse total shoulder arthroplasty (rTSA). Three-dimensional (3D) computed tomography (CT) and patient specific instrumentation (PSI) have improved the placement of the glenoid component, but the impact on clinical outcomes remains unclear. The purpose of this study was to compare short term clinical outcomes after rTSA based on intraoperative technique for central guidewire placement in a cohort of patients that had preoperative 3D planning. METHODS A retrospective matched analysis was performed from a multicenter prospective cohort of patients who underwent rTSA with preoperative 3D planning and a minimum of 2-year clinical follow-up. Patients were divided into 2 cohorts based on the technique utilized for glenoid guide pin placement: 1) Standard manufacture guide (SG) that was not customized or 2) PSI. Patient reported outcomes (PROs), active range of motion (ROM), and strength measures were compared between the groups. The ASES score was used to assess the minimum clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS). RESULTS One hundred seventy patients met the study criteria, including 56 performed with SGs and 122 with PSI. There was no difference in PROs between cohorts. There were no significant differences in the percentage of patients that achieved an ASES MCID, SCB, or PASS. Improvement in internal rotation to the nearest spinal level (p < .001) and at 90° (p = .002) were higher in the SG group and, but likely explained by differences in glenoid lateralization utilized. Improvement in abduction strength (p < .001) and external rotation strength (p = .010) were higher in the PSI group. CONCLUSION rTSA performed following preoperative 3D planning leads to similar improvement in PROs regardless of whether a SG or PSI are utilized intraoperatively for central glenoid wire placement. Greater improvement in postoperative strength was observed with the use of PSI, but the clinical significance of this finding is unclear.

Abstract
Machine learning (ML) has not yet been used to identify factors predictive for post-operative functional outcomes following arthroscopic rotator cuff repair (ARCR). We propose a novel algorithm to predict ARCR outcomes using machine learning. This is a retrospective cohort study from a prospectively collected database. Data were collected from the Surgical Outcome System Global Registry (Arthrex, Naples, FL, USA). Pre-operative and 3-month, 6-month, and 12-month post-operative American Shoulder and Elbow Surgeons (ASES) scores were collected and used to develop a ML model. Pre-operative factors including demography, comorbidities, cuff tear, tissue quality, and fixation implants were fed to the ML model. The algorithm then produced an expected post-operative ASES score for each patient. The ML-produced scores were compared to actual scores using standard test-train machine learning principles. Overall, 631 patients who underwent shoulder arthroscopy from January 2011 to March 2020 met inclusion criteria for final analysis. A substantial number of the test dataset predictions using the XGBoost algorithm were within the minimal clinically important difference (MCID) and substantial clinical benefit (SCB) thresholds: 67% of the 12-month post-operative predictions were within MCID, while 84% were within SCB. Pre-operative ASES score, pre-operative pain score, body mass index (BMI), age, and tendon quality were the most important features in predicting patient recovery as identified using Shapley additive explanations (SHAP). In conclusion, the proposed novel machine learning algorithm can use pre-operative factors to predict post-operative ASES scores accurately. This can further supplement pre-operative counselling, planning, and resource allocation. Level of Evidence: III.

Abstract
Arthroscopic repair of massive rotator cuff tears can be technically challenging but is achievable in many cases. Performing adequate releases are important for successful tendon mobility and avoiding excessive tension in the final repair, thus restoring the native anatomy and biomechanics. This Technical Note provides a step-by-step approach to release and mobilize massive rotator cuff tears to or near anatomical tendon footprints.

Abstract
A variety of surgical techniques are currently available to manage high-grade acromioclavicular (AC) separations, including hook plates/wires, nonanatomic ligament reconstruction, and anatomic cerclage with or without biological augmentation. Traditional reconstructions focused on the coracoclavicular ligaments alone and often were associated with high rates of recurrent deformity. Biomechanical and clinical data have suggested that additional fixation of the AC ligaments is beneficial. This Technical Note describes an arthroscopically assisted approach for combined reconstruction of the coracoclavicular and AC ligaments with a tensionable cerclage.

Abstract
BACKGROUND The purpose of this study was to compare recurrent instability rates between patients with on-track Hill-Sachs lesions who underwent arthroscopic labral repair (ALR) alone versus ALR with remplissage (ALR+R). Our hypothesis was that ALR+R would decrease the rate of recurrent instability, especially among subjects at high risk for recurrent instability after ALR, such as contact athletes with "near-track" Hill-Sachs lesions. METHODS We performed a multicenter, retrospective analysis of patients age 14-50 years with on-track Hill-Sachs lesions who underwent ALR with or without remplissage between Jan 2014 and Dec 2019, with minimum 2-year follow-up. Exclusion criteria included: prior ipsilateral shoulder surgery, glenoid bone loss (GBL) >15%, off-track Hill-Sachs lesion, concomitant shoulder procedures, and connective-tissue disorder. Age, gender, follow-up, and contact sport participation were recorded. GBL, Hills-Sachs Interval (HSI), glenoid track (GT), and distance to dislocation (DTD) were determined from preoperative MRIs. Affected shoulder range of motion (ROM), Western Ontario Shoulder Instability Index (WOSI) scores, Subjective Shoulder Value (SSV) scores, and recurrent dislocation/revision surgery status were also collected. A subgroup analysis was performed on "high-risk" patients (defined as contact sport participation with DTD < 10mm) from each cohort. RESULTS The ALR+R cohort had 56 subjects and the ALR cohort had 127. The ALR+R subjects had greater GBL (P=0.004) and larger HSI (P<0.001). Only 1 (1.8%) subject in the ALR+R cohort had a recurrent dislocation, and there were no revision surgeries. In comparison, the ALR cohort had 14 (11.0%) recurrent dislocations (P=0.040), and 8 (6.3%) revision surgeries (P=0.11). Univariate analysis showed that remplissage protected against recurrent dislocation (P=0.040), while younger age (P=0.004), contact sport participation (P=0.001), and increased GBL (P=0.048) was associated with recurrent dislocation. Multivariate analysis showed that HSI length (P=0.001) and contact sports (P=0.002) predicted recurrent dislocation. Among "high risk" subjects, there was only 1 (4.2%) recurrent instability event in the ALR+R group and 6 (66.7%) in the ALR alone group (P<0.001). The "high-risk" ALR+R subgroup also had significantly better final WOSI (P=0.008) and SSV (P=0.001) scores than the "high-risk" ALR subgroup. CONCLUSIONS Anterior shoulder instability patients with on-track Hill-Sachs lesions have lower recurrent dislocation rates with ALR+R, when compared to ALR alone. This is especially true for "high-risk" patients, such as contact athletes with DTD <10mm.

Abstract
» All-suture anchors or so-called "soft" anchors, initially adapted for labral repairs, have increased in popularity for use in rotator cuff repair because of their smaller size, decreased occupation of the footprint, improved points of fixation, ease of use, and ease of revision. » In limited series, soft anchors have demonstrated equivalent biomechanical and clinical performance compared with hard body anchors for rotator cuff repair. » Perianchor cyst formation can occur with both hard body and soft anchors. » Biomechanical and clinical data support aiming for vertical angles of insertion for soft anchors.

Abstract
BACKGROUND Restoring the native center of rotation (COR) in total shoulder arthroplasty (TSA) has been shown to improve postsurgical function, subjective outcomes, and implant longevity. The primary purpose of this study was to compare postoperative radiographic restoration of the humeral COR between short-stem and stemless humeral implants by evaluating the mean COR shift between the 2 techniques. Secondary outcomes evaluated were comparisons of COR shift outliers, humeral head implant thickness and diameter, direction of COR shift, and neck-shaft angle (NSA). METHODS This study was a multicenter retrospective comparative study using a consecutive series of primary anatomic TSA patients who received either a short-stem or stemless humeral implant. Radiographically, COR and NSA were measured by 2 fellowship-trained surgeons using the best-fit circle technique on immediate postoperative Grashey radiographs. RESULTS A total of 229 patients formed the final cohort for analysis that included 89 short stems and 140 stemless components. The mean COR shift for short stems was 2.7 mm (±1.4 mm) compared with 2.1 mm (±0.9 mm) for stemless implants (P < .001). The percentage of short-stem implant patients with a >2 mm COR difference from native was 66.0% (n = 62) compared with 47.4% (n = 64) for stemless (P = .006). The percentage of short-stem patients with a >4 mm COR difference from native was 17.0% (n = 16) compared with 3.0% (n = 4) for stemless (P < .001). The mean humeral implant head thickness for short stems was 18.7 ± 2.2 mm compared with 17.2 ± 1.3 mm for stemless implants (P < .001). The mean humeral head diameter for short stems was 48.7 ± 4.4 mm compared with 45.5 ± 3.5 mm for stemless implants (P < .001). The NSA for the short-stem cohort was 136.7° (±3.6°) compared with 133.5° (±6.0°) for stemless (P < .001). CONCLUSIONS Stemless prostheses placed during TSA achieved improved restoration of humeral head COR and were less likely to have significant COR outliers compared with short-stem implants.

Abstract
PURPOSE To compare return to sports, functional outcomes, and recurrences rates between female and male athletes following arthroscopic Bankart repair (ABR). METHODS A retrospective comparative study was performed between male and female athletes who underwent an ABR between January 2008 and December 2019. Sports practiced primarily by men in our practice (including rugby, soccer, boxing, and martial arts) were excluded. Functional outcomes included the Rowe score, visual analog scale (VAS) for pain, and shoulder-dependent sports ability measured with the Athletic Shoulder Outcome Scoring System (ASOSS). Return to sport, recurrence, and revisions were evaluated. Additionally, we assessed the period (months) between surgery and recurrence events. RESULTS A total of 58 female and 106 male patients were available for analysis at a median follow-up of 60 (interquartile range [IQR], 36-84) months. Ninety-one percent of the patients (n = 150) returned to sports and 84% (n = 126) returned to their preinjury level at a median of 6 months (IQR, 5-8) postoperatively. There were no differences in the rate of return to sports between females and males (91 vs 92% respectively, P = .997). There were no differences between the groups regarding postoperative functional outcomes, with most patients achieving the minimal clinically significant difference (Rowe: 98% female and 99% male, P = .584; ASOSS: 100% female and 99% male, P = .646). The overall recurrence rate was 9.7% (n = 16), with a rate of 10.3% (n = 6) in female and 9.4% (n = 10) in male athletes (P = .851). Time to event analysis showed that the median time to recurrence was 48 months in both groups (P = .848). The overall revision rate was 3% (n = 4), without significant differences between groups (P = .556). CONCLUSIONS When compared within similar sports, there does not appear to be sex-related differences in functional outcomes, recurrence, or return to play following ABR. LEVEL OF EVIDENCE III, retrospective comparative study.

Abstract
Purpose The purposes of this study were to investigate the difference in value (benefit to cost ratio) of dermal allograft superior capsular reconstruction (SCR) versus reverse total shoulder arthroplasty (rTSA) for the treatment of massive rotator cuff tears (MRCTs) without arthritis; to compare the patient populations selected for the operations and report pre- and postoperative functional data; and to understand other characteristics of the 2 operations, including operating time, use of institutional resources, and complications. Methods A retrospective, single-institution analysis during the study period 2014-2019 with MRCT treated with SCR or rTSA by 2 surgeons with complete institutional cost data and minimum 1-year clinical follow-up with American Shoulder and Elbow Surgeons (ASES) score. Value was defined as ΔASES/(total direct costs/$10,000). Results Thirty patients underwent rTSA and 126 patients SCR during the study period with significant differences noted in patient demographics and tear characteristics between the groups (patients who underwent rTSA were older, less male, had more pseudoparalysis, had greater Hamada and Goutallier scores, and had more proximal humeral migration). Value was 25 and 29 (ΔASES/$10,000) for rTSA and SCR, respectively (P = .7). The total costs of rTSA and SCR were $16,337 and $12,763, respectively (P = .7). Both groups experienced substantial improvements in ASES scores: 42 for rTSA vs 37 for SCR (P = .6). The operative time for SCR was much longer (204 vs 108 minutes, P < .001) but complication rate lower (3% vs 13%, P = .02) versus rTSA. Conclusions In a single institutional analysis of the treatment of MRCT without arthritis, rTSA and SCR demonstrated similar value; however, the value calculation is highly dependent on institution specific variables and duration of follow-up. The operating surgeons demonstrated different indications in selecting patients for each operation. rTSA had an advantage over SCR in shorter operative time, whereas SCR demonstrated a lower complication rate. Both SCR and rTSA are demonstrated to be effective treatments for MRCT at short-term follow-up. Level of Evidence III, retrospective comparative study.

Abstract
Reconstruction of glenoid bone loss is a difficult but often required component of shoulder arthroplasty. A variety of free autografts or allografts have been proposed for reconstruction. While Latarjet is well accepted for the management of anterior instability, the use of a coracoid graft has not been described in conjunction with shoulder arthroplasty. We propose that anterior and central glenoid bone defects can be reconstructed with the coracoid process. to provide a vascularized local structural autograft. Level of Evidence: IV.

Abstract
BACKGROUND Advances in the understanding and management of glenoid bone loss in shoulder instability have led to the development of alternative bony reconstruction techniques to the Latarjet using free bone grafts, but little is known about surgeon adoption of these procedures. This study sought to characterize surgeon variation in the use of glenoid bone reconstruction procedures for shoulder instability and ascertain reasons underlying procedure choice. METHODS A 9-question survey was created and distributed to 160 shoulder surgeons members of the PacWest Shoulder and Elbow Society, of whom 65 (41%) responded. The survey asked questions regarding fellowship training, years in practice, surgical volume, preferred methods of glenoid bone reconstruction, and reasons underlying treatment choice. RESULTS All surgeons completed a fellowship, with an equal number of sports medicine fellowship-trained (46%) and shoulder and elbow fellowship-trained (46%) physicians. The majority had been in practice for at least 6 years (6-10 years: 25%; >10 years: 59%). Most (78%) performed ≤10 glenoid bony reconstructions per year, and 66% indicated that bony procedures represented <10% of their total annual shoulder instability case volume. The open Latarjet was the preferred primary reconstruction method (69%), followed by open free bone block (FBB) (22%), arthroscopic FBB (8%), and arthroscopic Latarjet (1%). Distal tibia allograft (DTA) was the preferred graft (74%) when performing an FBB procedure, followed by iliac crest autograft (18%), and distal clavicle autograft (6%). The top 5 reasons for preferring Latarjet over FBB were the sling effect (57%), the autologous nature of the graft (37%), its robust clinical evidence (22%), low cost (17%), and availability (11%). The top 5 reasons for choosing an FBB procedure were less anatomic disruption (58%), lower complication rate (21%), restoration of articular cartilage interface (16%), graft versatility (11%), and technical ease (11%). Only 20% of surgeons indicated always performing a bony glenoid reconstruction procedure in the noncontact athlete with less than 20% glenoid bone loss. However, that percentage rose to 62% when considering a contact athlete with the same amount of bone loss. CONCLUSIONS Although open Latarjet continues to be the most popular glenoid bony primary reconstruction procedure in shoulder instability, nearly 30% of shoulder surgeons in the western United States have adopted FBB techniques as their preferred treatment modality--with DTA being the most frequently used graft. High-quality comparative clinical effectiveness research is needed to reduce decisional conflict and refine current evidence-based treatment algorithms.

Abstract
BACKGROUND The primary purpose of this study was to compare 2-year anatomic total shoulder arthroplasty (TSA) functional and radiographic outcomes between Walch type A and B glenoids treated with an all-polyethylene glenoid designed for hybrid fixation with peripheral cement and central osseous integration. The secondary purpose was to evaluate outcomes based on central peg technique. The hypotheses were that there would be no difference in short-term radiographic or functional outcome scores based on preoperative glenoid morphology or central peg technique. METHODS We performed a multicenter retrospective review of patients who underwent TSA with the same hybrid all-polyethylene glenoid and had minimum 2-year follow-up. Patient-reported outcomes and radiographic outcomes were analyzed based on preoperative Walch morphology and central peg technique. Radiographic analysis included preoperative glenoid morphology; preoperative and postoperative glenoid version, glenoid inclination, and posterior humeral head subluxation; and postoperative glenoid radiolucencies according to the Wirth and Lazarus classifications. RESULTS A total of 266 patients with a mean age of 64.9 ± 8.2 years were evaluated at a mean of 28 months postoperatively. Postoperatively, there were significant improvements in all functional outcome measures (P < .001), range-of-motion measures (forward elevation, external rotation at 0°, external rotation at 90°, internal rotation by spinal level, and internal rotation at 90°; P < .001), and strength measures (Constant, external rotation, and modified belly press; P < .001). There were no clinically meaningful differences in functional outcomes or statistically significant differences in radiographic appearance between Walch type A and B glenoids. Subgroup analysis revealed that glenoids with a cemented central peg had the worst radiographic outcomes based on Lazarus scoring. CONCLUSION Patients undergoing TSA with a hybrid in-line pegged glenoid have excellent clinical outcomes at short-term follow-up regardless of preoperative glenoid morphology. Different central peg techniques do not appear to play a significant role in the risk of glenoid component lucencies at 2 years postoperatively.

Abstract
BACKGROUND Surgical management of anterior shoulder instability continues to evolve. The clinical effectiveness of arthroscopic Bankart repair with remplissage (REMP) in patients with increasing glenoid bone loss (GBL) has not been thoroughly compared with Latarjet. PURPOSE/HYPOTHESIS The purpose of this study was to compare 2-year outcomes of REMP versus open Latarjet in patients with >15% GBL. We hypothesized that there would be no difference. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A multicenter, retrospective study was performed on a consecutive series of patients who underwent primary REMP or Latarjet by 4 shoulder specialists between August 2013 and December 2019 for >15% GBL. Procedure performance was based on shared decision making between the surgeon and patient. Baseline and 2-year postoperative range of motion (ROM) and the following patient-reported outcomes (PROs) were collected: Western Ontario Shoulder Instability Index, Single Assessment Numeric Evaluation, and visual analog scale for pain. Return to sport, satisfaction, complications, recurrence, and revisions were reviewed. RESULTS A total of 47 patients were available for study, including 22 who underwent REMP and 25 who underwent Latarjet. Baseline demographic characteristics, ROM, and PROs were similar between the groups. Mean preoperative GBL (REMP 25.8% ± 7.8% vs Latarjet 25.1% ± 9.0%; P = .800) and off-track lesions (REMP 59.1% vs Latarjet 44.0%; P = .302) were similar. Postoperative change in external rotation favored Latarjet (10° ± 22° vs -4° ± 13°; P = .017). Postoperative PROs, return to the sports (86.4% vs 87.5%; P = .99), and satisfaction (95.5% vs 95.8%; P = .99) were similar between groups. There were no recurrent dislocations in either group. One infected hematoma was encountered in the Latarjet cohort. CONCLUSION At short-term follow-up, the hypothesis was upheld. REMP and Latarjet provided similar outcomes for patients with >15% GBL, although REMP patients experienced slightly decreased external rotation. Although larger series and longer-term follow-ups are required, remplissage may be considered in patients with >15% glenoid bone loss.

Abstract
➢ A Hill-Sachs lesion (HSL) is a compression fracture on the posterolateral humeral head that can increase the risk of recurrent shoulder instability after isolated arthroscopic Bankart repair. ➢ Remplissage involves capsulotenodesis of the infraspinatus tendon and posterior capsule into the HSL to prevent its engagement with the glenoid rim through extra-articular conversion and restraint against humeral head anterior translation. ➢ The glenoid track concept can be applied preoperatively and intraoperatively to evaluate risk of recurrence and help direct clinical management options for recurrent shoulder instability. ➢ Recent literature supports expanding indications for remplissage to include patients with on-track HSLs who are at increased risk of recurrence including collision athletes, military personal, and patients with joint hyperlaxity. ➢ New techniques and suture constructs have demonstrated improved biomechanical strength while avoiding the need to access the subacromial space.

Abstract
BACKGROUND Although preoperative function and range of motion (ROM) are determinants of postoperative outcome following reverse shoulder arthroplasty (RSA), there is limited data on the influence of preoperative rotator cuff status. The purpose of this study was to evaluate the relationship between preoperative rotator cuff physiologic cross-sectional area (PCSA) and strength on postoperative RSA outcome. METHODS A retrospective review was conducted on 53 primary RSAs from a multicenter database performed between 2015 and 2019 using a 135° humeral neck-shaft angle. Preoperative magnetic resonance imaging and computed tomographic scans were used to assess the PCSA of the subscapularis, supraspinatus, infraspinatus, and teres minor. American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores, ROM, and strength were measured preoperatively and at a minimum of 2 years postoperatively. Correlation coefficients were used to determine the relationship between variables. RESULTS There were no significant correlations between preoperative PCSA of any rotator cuff muscles and postoperative ASES scores. Preoperative subscapularis PCSA positively correlated with change in belly press (BP) strength following RSA (⍴ = 0.37, P = .006). Preoperative abduction strength was significantly correlated with postoperative abduction strength (⍴ = 0.297, P = .006). Preoperative external rotation (ER) strength was significantly correlated with postoperative ER (⍴ = 0.378, P = .005) and abduction (⍴ = 0.304; P = .032) strength. Preoperative BP strength negatively correlated with postoperative ASES (⍴ = -0.283, P = .042) but positively correlated with postoperative BP (⍴ = 0.411, P = .001) and abduction (⍴ = 0.367, P = .009) strength. CONCLUSION With the use of a 135° humeral implant, there is limited correlation between preoperative PCSA and postoperative outcomes 2 years following RSA; the only significant correlation was between preoperative subscapularis PCSA and postoperative BP strength. Preoperative strength is positively correlated with postoperative strength but not ROM or ASES scores.
