RESUMO
PURPOSE: To provide an overview of the existing literature on subacromial balloon spacers for the treatment of massive irreparable rotator cuff tears, in an effort to inform surgeons of the procedure's clinical effectiveness. METHODS: The PubMed, Scopus, and Ovid EMBASE databases were queried to identify studies evaluating the clinical, radiographic, and patient-reported outcomes of patients indicated for subacromial balloon spacer implantation. The following datapoints were extracted: study demographics, patient baseline characteristics, and postoperative outcomes of interest. Outcomes were evaluated at baseline and at the longest available follow-up period. RESULTS: A total 766 patients were included among 22 included studies, with an average follow-up of 27.54 months. Improvements were seen for all clinical and patient-reported outcomes: forward elevation (ranging from 9.20 to 90.00° improvement), external rotation (ranging from 2.00 to 22.00°), abduction (ranging from 14.00 to 95.00°), Total Constant Score (ranging from 7.70 to 50.00), American Shoulder and Elbow Surgeons score (ranging from 24.60 to 59.84), Oxford Shoulder Score (ranging from 7.20 to 22.20), and pain score (ranging from 3.57 to 6.50). Minimal differences were seen in acromiohumeral interval (ranging from -2.00 to 1.27). Reoperation and complication rates ranged from 0% to 33% and 0% to 19.64%, respectively. CONCLUSIONS: The short-term results of subacromial balloon spacers for management of massive rotator cuff tears demonstrate clinically relevant improvements in shoulder range of motion and substantial improvements in patient-reported outcome measures. Of note, minimal change in acromiohumeral interval was seen on postoperative radiography, and wide variations in complication and reoperation rates were reported across studies. LEVEL OF EVIDENCE: Level IV, systematic review of Level I-IV studies.

BACKGROUND: Solid organ transplant (SOT) recipients are commonly prescribed immunosuppressive therapies which may predispose patients to higher infection and complication rates following total shoulder arthroplasty. This article aims to analyze the effects SOT and subsequent immunosuppressive regimens have on the functional and patient-reported outcomes of total shoulder arthroplasties. METHODS: A single institution, multisurgeon retrospective case-control study investigating the functional and patient-reported outcomes of shoulder arthroplasty after SOT was conducted between the years of 2010 and 2020. To be included in the study, patients must have undergone SOT prior to primary total shoulder arthroplasty. A 4:1 match-paired control group lacking SOT prior to arthroplasty was then constructed. Thirty-four SOT patients (18 males and 16 females) and 136 control patients (77 male and 59 female) were included in the study. Patients were analyzed who underwent SOT prior to shoulder arthroplasty, with outcomes compared to controls that only underwent arthroplasty. The primary outcomes include range of motion and strength in forward elevation, external rotation, and internal rotation, and patient reported outcomes. RESULTS: There was no significant difference in improvement for range of motion and strength between the 2 cohorts, but within each cohort, improvement was statistically significant. In the SOT patients, forward elevation improved by 56° ± 52°, external rotation increased by 13° ± 20°, and internal rotation increased by 2 vertebral levels. In the non-SOT patients, forward elevation improved by 45° ± 51°, external rotation increased by 16° ± 25°, and internal rotation increased by 3 vertebral levels. SOT patients had equivocal visual analog scale pain and Simple Shoulder Test scores but lower American Shoulder and Elbow Surgeons (59 ± 13 vs. 79 ± 2; P = .002) and SANE (61 ± 30 vs. 84 ± 17; P < .001) scores than non-SOT patients. Complication rates were not significantly higher in the SOT group (15% vs. 6%; P = .05), but incidence of surgical revisions was not significantly different (SOT = 3%; non-SOT = 5%; P = .59). CONCLUSION: Shoulder arthroplasty is a safe, effective surgical intervention for improving shoulder function in patients with a history of SOT. Despite being on chronic immunosuppressive regimens, our solid organ transplants had comparable clinical outcomes and revision rates, but higher complication rates.
RESUMO
BACKGROUND: Although cementation of humeral stems has long been considered the gold standard for anatomic shoulder arthroplasty (aTSA), cementless, or press-fit, fixation offers a relatively cheaper and less demanding alternative, particularly in the setting of a revision procedure. However, this approach has been accompanied by concerns of implant loosening and high rates of radiolucency. In the present study, we performed a propensity-matched comparison of clinical and patient-reported outcomes between cemented and cementless fixation techniques for aTSA. We hypothesized that cemented fixation of the humeral component would have significantly better implant survival while providing comparable functional outcomes at final follow-up. METHODS: This study was a retrospective comparison of 50 shoulders undergoing aTSA: 25 using cemented humeral fixation vs. 25 using press-fit humeral fixation. Patients in the 2 groups were propensity matched according to age, sex, and preoperative American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score. Primary outcome measures included range of motion (ROM) (forward elevation, external rotation, internal rotation), patient-reported outcomes (ASES, Simple Shoulder Test [SST], visual analog scale [VAS]), and implant survival. RESULTS: At baseline, the 2 fixation groups were similar in regard to age, sex, body mass index, preoperative ASES score, and surgical indication. Mean follow-up was 11.7 ± 4.95 years in the cemented cohort and 9.13 ± 3.77 years in the press-fit cohort (P = .045). Both groups demonstrated significant improvements postoperatively in all included ROM and patient-reported outcomes. However, press-fit patients reported significantly better VAS, ASES, and SST scores. Mean VAS pain score was 1.1 ± 1.8 in press-fit patients and 3.2 ± 3.0 in cemented patients (P = .005). The mean ASES score was 87.7 ± 12.4 in press-fit patients and 69.5 ± 22.7 in cemented patients (P = .002). Lastly, the mean SST score was 9.8 ± 3.1 in press-fit patients and 7.7 ± 3.7 in cemented patients (P = .040). Both fixation techniques provided lasting implant survivorship with only a single revision operation in each of the cohorts. CONCLUSION: Herein, we provide a propensity-matched, long-term comparison of patients receiving anatomic shoulder arthroplasty stratified according to humeral stem fixation technique. The results of this analysis illustrate that both types of humeral fixation techniques yield durable and significant improvements in shoulder function with similar rates of survival at 10 years of follow-up.

BACKGROUND: Increased body mass index (BMI) is a potential risk factor for poorer outcomes and complications. However, the influence of BMI on the long-term outcomes of anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) remains to be fully elucidated. METHODS: Institutional records were queried to identify patients who underwent primary total shoulder arthroplasty (TSA) between 2009 and 2020 with a minimum of 2 years of clinical follow-up. Retrospective review was performed to collect demographic characteristics; comorbidity status; and range-of-motion and strength measurements in forward elevation, external rotation, and internal rotation. Patients were contacted by telephone to provide patient-reported outcomes (PROs). Patients were stratified into 3 cohorts by BMI: underweight or normal weight (U/NW, BMI ≤25 kg/m2), overweight (OW, BMI >25 to ≤30 kg/m2), and obese (BMI >30 kg/m2). RESULTS: Among 466 TSA patients, 245 underwent aTSA whereas 221 underwent rTSA. In the aTSA cohort, 40 patients were classified as U/NW; 72, as OW; and 133, as obese. Comparatively, the rTSA cohort was composed of 33 U/NW, 79 OW, and 209 obese patients. Patients in the aTSA and rTSA cohorts had an average follow-up period of 5.8 ± 3.2 years and 4.5 ± 2.3 years, respectively. No differences in age at surgery were found in the aTSA group (U/NW vs. obese, 65.2 ± 7.9 years vs. 61.9 ± 8.9 years; P = .133); however, in the rTSA cohort, BMI was found to be inversely related to age at surgery (U/NW vs. obese, 72.4 ± 8.8 years vs. 65.7 ± 8.3 years; P < .001). Across all BMI cohorts, patients saw great improvements in range of motion and strength. Postoperative PROs after TSA did not vary by BMI in terms of Single Assessment Numeric Evaluation, Simple Shoulder Test, visual analog scale pain, and American Shoulder and Elbow Surgeons scores. There was no significant difference in survival rates at 10-year follow-up in the aTSA cohort (U/NW vs. obese, 95.8% vs. 93.2%; P = .753) or rTSA cohort (U/NW vs. obese, 94.7% vs. 94.5%; P = .791). CONCLUSION: With dramatic improvements in range of motion, minimal differences in PROs, and high rates of implant survival, TSA is a safe and effective treatment option for all patients, including overweight and obese patients.

PURPOSE: The utilization of reverse total shoulder arthroplasty now exceeds the incidence of anatomic shoulder arthroplasty. Previous mid-to-long-term studies on rTSA have reported a decrease in shoulder function as follow-up increased. The purpose of this study was to provide data on mid-term outcomes and implant survival in a series focusing on reverse total shoulder arthroplasty. MATERIALS AND METHODS: Demographic information such as age at surgery, revision surgery status, BMI, and smoking status were recorded. The clinical endpoints measured in this study were range of motion scores (forward elevation, external rotation, internal rotation) and patient reported outcomes (VAS, ASES, SST). Radiographic variables captured included preoperative glenoid morphology, humeral lucency, and glenoid loosening. RESULTS: Fifty-six shoulders were included in this study. The overall mean age at surgery was 72.5 ± 7.2 years with an average follow-up time of 6.8 ± 3.5 years. The mean BMI was 28.1 ± 5.5. All measurements of range of motion saw significant and sustained improvements. Overall, forward elevation improved from 82° preoperatively to 133° postoperatively (p < 0.01). External rotation improved from 23° preoperatively to 36° (p < 0.01), while internal rotation improved from L3 to L1 (p = 0.05). ASES scores improved from 31 preoperatively to 70 postoperatively (p < 0.01). SST scores improved from 2 preoperatively to 7 (p < 0.01). VAS pain index scores improved from 6 to 2 following surgery (p < 0.01). Postoperative scapular notching was seen in 18 patients at final follow-up. Glenoid loosening was seen in 3 shoulders. Humeral loosening was seen in 18 shoulders. Tuberosity resorption was seen in 8 shoulders. The 5 year survival estimate was 98%, and the 10 year survival estimate was 83%. CONCLUSION: In this series, we found that rTSA provides mid-term improvements in range of motion in patients while reducing pain levels. When considered together, this demonstrates that most patients undergoing rTSA can have excellent use of their shoulder from age at surgery to end-of-life.

BACKGROUND: As of 2018, upwards of 42% of the US adult population was considered obese based on body mass index (BMI) scales. With the annual number of total joint replacements increasing, this study aimed to evaluate the impact BMI has on anatomic total shoulder arthroplasty (aTSA) outcomes. METHODS: This was a retrospective analysis of 128 shoulders requiring primary aTSA. Patients were stratified into 3 cohorts based on their BMI at surgery: underweight/normal weight (U/NW; BMI ≤25.0), overweight (25.0 < BMI ≤ 30.0), and obese (BMI >30.0). BMI was separately analyzed as a continuous variable. Clinical endpoints were range of motion scores, including forward elevation, external rotation, and internal rotation, and patient-reported outcomes, including visual analog scale (VAS) scores, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) scores, and the Simple Shoulder Test (SST). Survivorship curves were calculated using Kaplan-Meier analysis. RESULTS: Forty-four, 50, and 34 patient shoulders were in the U/NW, overweight, and obese cohorts, respectively. The mean follow-up time was 11.4 years. The U/NW cohort had more females (73%) compared with the overweight (34%; P = .0030) and obese (35%; P = .0015) groups; no differences were seen in revision rates. BMI was negatively correlated with age at surgery (r = -0.19, P = .014); it was not correlated with any of the 6 postoperative clinical endpoints. All 3 cohorts saw significant improvements in forward elevation, external rotation, internal rotation and VAS, ASES, and SST scores when compared preoperatively to postoperatively (P < .001). There were no significant differences between the 3 cohorts with respect to postoperative range of motion. Postoperative ASES scores were higher for the overweight cohort (82.6 ± 18.6) compared with both the U/NW (63.0 ± 25.1) and obese cohorts (70.5 ± 26.8) (P < .001). The overweight cohort also had higher SST (P = .0012) postoperative scores compared with the U/NW and obese cohorts; VAS scores were comparable between groups (P = .12). The nonobese (BMI <30) group (n = 94) showed 5-, 10-, and 15-year implant survival of 98.9%, 94.9%, and 83.9%, respectively compared to 97.1%, 93.7%, and 87.0% in the obese (BMI ≥30) group (n = 34). The log rank test revealed no significant difference in survival curves (P = .82). CONCLUSION: To our knowledge, this is the longest follow-up study analyzing clinical endpoints stratified by BMI for aTSA. We saw that patients with a higher BMI required shoulder replacement at a significantly younger age. However, we also report that regardless of BMI, all patients saw significant improvements in patient-reported outcomes and range of motion scores postoperatively.

BACKGROUND: Superior migration of the humeral head has been linked with rotator cuff dysfunction and glenoid loosening after total shoulder arthroplasty (TSA). We aimed to determine if superior migration was associated with poor shoulder function following anatomic TSA at long-term follow-up. METHODS: In this retrospective cohort study, we reviewed patients undergoing TSA by a single surgeon at an urban, academic institution. To study the effect of superior migration on TSA outcomes, we stratified the cohort by ≥ and <7 mm of acromiohumeral interval (AHI) and compared range of motion and patient reported outcomes (PROs). Clinical variables included preoperative and postoperative forward elevation (FE), internal rotation, external rotation, visual analog scale, American Shoulder and Elbow Surgeons shoulder score, and Simple Shoulder Text score. Radiographic variables included immediate postoperative and long-term follow-up AHI, lateral humeral offset, and glenoid loosening scores. RESULTS: After applying exclusion criteria, 121 TSAs were included. The mean age was 63.9 ± 9.5 years, and 66 surgeries (55%) were in male patients. The mean follow-up for our cohort was 11.2 years (range, 5-26 years). Nine shoulders underwent revision surgery. All range of motion and PROs improved significantly from preoperative to the most recent postoperative follow-up. The mean AHI immediately following surgery was 10.9 ± 4.1 mm, while the mean AHI at most recent follow-up was 8.4 ± 3.5 mm. Glenoid loosening was observed in 29 (23.8%) shoulders at the most recent follow-up appointment. Although AHI correlated weakly with FE (r = 0.252; P = .006), we did not observe a clear threshold of migration which led to degraded function. Importantly, glenoid loosening was not related to AHI at long-term follow-up (P = .631). None of FE, internal rotation, external rotation, visual analog scale, American Shoulder and Elbow Surgeons shoulder score, Simple Shoulder Text, or revisions were significantly different between patients with ≥ and <7 mm of AHI. CONCLUSION: Our results suggest that anatomic TSA provides durable improvements to pain, function, and PROs despite changes to the AHI.

Introduction: The objective was to investigate outcomes in reverse total shoulder arthroplasty (RTSA) in patients affected by the COVID-19 pandemic shutdown. We hypothesized that patients undergoing RTSA in early 2020 would have decreased access to physical therapy (PT) and worse postoperative outcomes compared to historical controls. Materials and Methods: Patients who received primary RTSA between 1/1/2020 to 3/17/2020 were included and patients who received primary RTSA between 1/1/2019 to 3/17/2019 were used as a control group. Retrospective chart review was performed, and patient reported outcomes were recorded at an average of 2.69 ± 0.06 years and a minimum of 1 year postoperatively. Patient data were collected and statistically analyzed using the 2-sample t-test and Chi-square test. The Mann Whitney U test and Fisher's Exact test were used when appropriate. Results: 38 patients in 2020 were included in this study and compared to 31 patients in 2019. RTSA performed in 2019 had improvements in forward elevation (FE) (95.7º ± 47.2º to 144.7º ± 17.2º, p<0.001), but not in external rotation (ER) (32.5º ± 20.3º to 41.0º ± 13.3º, p=0.15), or internal rotation (IR) (S1 to L5, p=0.76). RTSA 2020 cases had improvements in FE (111.5º ± 40.3 to 132.8º ± 30.6, p=0.016), but not ER (31.9º ± 18.2 to 35.7º ± 15.9, p=0.36) or IR (S1 to L5, p=0.13). Patients in 2019 (FE: 4 to 5-, p<0.001; ER: 4+ to 5-, p=0.003; IR: 5- to 5, p<0.001) and 2020 (FE: 4 to 5-, p<0.001; ER: 4+ to 5, p<0.001; IR: 5- to 5, p=0.02) both experienced improvements in strength. Patients in 2020 initiated PT later (2019: 39.3 ± 27.3 days, 2020: 57.1 ± 35.5 days, p=0.028) and completed less PT sessions (2019: 20.7 ± 11.1, 2020: 12.9 ± 6.6, p<0.001) than patients in 2019. In the 2020 cohort, 10.5% (4/38) did not complete any PT, 34.2% (13/38) reported a delay in initiating PT, and 47.4% (18/38) reported that their recovery was negatively affected by the COVID-19 pandemic. At final follow-up, patients in 2020 reported a mean SANE score of 73.6 ± 17.5 on their affected shoulder and a mean VAS score of 1.68 ± 1.23. Discussion: Despite a delay in initiating PT and completing less PT overall, patients who received RTSA in 2020 experienced significant improvements in ROM and strength at final follow-up and were comparable to the 2019 patients.
RESUMO
BACKGROUND: We aimed to characterize the long-term clinical and radiographic outcomes of total shoulder arthroplasty (TSA) in patients aged < 60 years. We hypothesized meaningful improvements in shoulder functionality and pain with TSA and an acceptably low rate of prosthesis complications and revisions. METHODS: This was a retrospective cohort study of 29 patients (34 shoulders) undergoing TSA before age 60 years with a minimum follow-up period of 10 years. Shoulder range of motion, functionality (American Shoulder and Elbow Surgeons and Simple Shoulder Test scores), and pain (visual analog scale score) were evaluated. Radiographs were assessed for lateral humeral offset, the acromiohumeral interval, and glenoid loosening. RESULTS: The mean age of the patients was 54.4 ± 5.5 years (range, 35.5-59.8 years), with a mean follow-up period of 16.1 ± 4.5 years (range, 10.0-26.1 years). In patients aged < 60 years, TSA significantly improved forward elevation (from 119° ± 26° to 146° ± 21°, P = .0002), external rotation (from 21° ± 25° to 52° ± 15°, P = .0001), and internal rotation (from L5 to L1, P = .002). Additionally, TSA significantly increased American Shoulder and Elbow Surgeons scores (from 32 ± 20 to 64 ± 27, P = .0008) and Simple Shoulder Test scores (from 3 ± 2 to 7 ± 4, P = .0004) and reduced visual analog scale pain scores (from 7 ± 3 to 3 ± 3, P = .0001). Radiographically, there was no significant difference in mean lateral humeral offset (13 ± 6 mm vs. 10 ± 12 mm, P = .472) or the mean acromiohumeral interval (20 ± 4.2 mm vs. 16 ± 6 mm, P = .061) between immediate postoperative and final follow-up radiographs. Radiographic evidence of glenoid loosening was noted in 2 patients. Complications occurred in 6 patients (17.6%), all of which were cases of aseptic glenoid loosening. Ultimately, 4 patients underwent conversion to a reverse TSA and 2 underwent arthroscopic glenoid removal. The rate of prosthesis survivorship was 97.1% (95% confidence interval [CI], 91.4%-100%) at 10 years, 85.4% (95% CI, 73.7%-97.2%) at 15 years, and 80.1% (95% CI, 65.1%-98.4%) at 20 years. DISCUSSION: TSA consistently improved shoulder functionality and reduced pain while limiting the need for further revisions. These findings suggest that TSA is a viable treatment option for glenohumeral arthritis in younger patients.

BACKGROUND: Avascular necrosis (AVN) of the humeral head is a debilitating pathology that can be managed with an array of treatments depending on disease staging. Humeral head arthroplasty for AVN has demonstrated good short-term improvements in pain and range of motion, but the published long-term outcomes data are limited. The objective of this study was to report long-term survivorship and outcomes for patients undergoing hemiarthroplasty (HA) or total shoulder arthroplasty (TSA) for the treatment of AVN of the humeral head. METHODS: The practice of one fellowship-trained shoulder surgeon was queried for the surgical treatment of AVN of the humeral head via appropriate International Classification of Diseases, Ninth and Tenth Revision, codes. Sixteen shoulders that met inclusion criteria were identified. Demographics included the radiographic stage, age, sex, American Society of Anesthesiologists (ASA) score, and body mass index. The primary endpoint was survivorship of the implant. Secondary endpoints were range of motion in forward elevation, internal and external rotation, visual analog scale for pain, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form score, and the Simple Shoulder Test score. RESULTS: Of the 16 shoulders included in the study, 10 underwent HA and 6 underwent TSA. The TSA cohort was significantly older (mean 60.5 vs. 44.2, P = .005), with a higher mean ASA score (mean 3.0 vs. 2.13, P = .02) than the HA group. The 10-year survivorship rates were 88.9% for HA and 80% for TSA with no significant difference between groups. Survivorship data were available for a mean 13.0 ± 5.6 years' follow-up in the HA group and 13.8 ± 4.8 years in the TSA group. When compared to one another, the results between HA and TSA only differed in internal rotation, which was statistically significantly improved in the TSA group compared with HA (2.3 ± 2.6 compared with -3.0 ± 5.0, P = .03). CONCLUSION: The survivorship of both TSA and HA for the treatment of AVN was at least 80% at 10 years. Secondary endpoints, such as range of motion, pain, and shoulder function, improved significantly postoperatively in each cohort and were similar between the 2 groups, except for internal rotation, which had improved significantly more in the TSA group than in HA. Both TSA and HA are viable options for the treatment of AVN, each with durable long-term survival.

BACKGROUND: Implantation of the MICRA Leadless pacemaker requires the use of a 27 French introducer, blunt delivery system and device fixation to the myocardium via nitinol tines. While prior studies have proven its safety, it is unclear whether performing this procedure with uninterrupted anticoagulation exposes patients to increased risks. We sought to investigate the feasibility and safety of continuing therapeutic anticoagulation during the periprocedural period. METHODS: We evaluated all patients undergoing MICRA placement at our institution between April 2014 and August 2018 with complete follow-up data (n = 170). Patients were stratified into two groups: those on active anticoagulation (OAC, n = 26), defined as having an International normalized ratio >2.0 or having continued a direct oral anticoagulant, and those not anticoagulated (Off-OAC, n = 144). We evaluated for a composite outcome of all major complications, including access site complications and pericardial effusion. RESULTS: OAC and Off-OAC groups had similar mean age (74 ± 13 vs 75 ± 13 years; P = .914). The OAC group had a nonsignificantly lower prevalence of end-stage renal disease (8% vs 17%; P = .375) and aspirin use (27% vs 47%; P = .131). Those in the OAC group were more likely to be on warfarin than those in the Off-OAC group (81% vs 30%; P < .001). The rate of the composite endpoint was similar between the OAC and Off-OAC groups (3.8 % vs 1.4%, respectively; P = .761). Length of stay was similar between groups (1.3 ± 2.6 vs 2.3 ± 3.4 days; P = 0.108). CONCLUSION: Continuation of therapeutic anticoagulation during MICRA implantation appears to be feasible, safe and associated with shorter hospitalization among appropriately selected individuals.

Solid organ transplants (SOT) have evolved into life-saving interventions for end-stage diseases affecting vital organs. Advances in transplantation techniques, donor selection, and immunosuppressive therapies have enhanced outcomes, leading to a growing demand for SOT. Patients with a solid organ transplant are living long enough to develop the same pathologies which are indicated for joint replacement surgery in the general population. SOT patients who undergo a total hip, knee, or shoulder arthroplasty do similarly in the context of clinical outcomes and implant survival when compared to the general population. These immunosuppressed patients tend to have higher complication rates in the short-term following surgery. Prudent management of these patients in the short-term may be necessary, but patients can expect to do well otherwise.
RESUMO
OBJECTIVES: The purpose of this study was to identify the 50 most-cited publications relating to lacrosse since 1990 and conduct a bibliometric analysis of the identified studies. METHODS: Clarivate Analytics Web of Science database was queried to identify all publication titles, abstracts, and keywords for the term 'lacrosse' on 9 June 2023. The resulting articles were sorted by total number of citations. Titles and abstracts were included based on their relevance to lacrosse. Once the 50 most cited articles were identified, each article was further analyzed to obtain author name, publication year, country of origin, journal name, article type, research topic, competition level, total number of citations, and the level of evidence. Citation density (total number of citations/years since publication) was calculated and recorded for each of the most-cited studies. RESULTS: The 50 most-cited articles were cited 4237 of times with an average of 84 citations per article. The most cited article was cited 637 (15.0%) times. The articles came from 2 different countries, with the United States and Australia comprising 49 and 1 articles, respectively. All articles were published in English. The American Journal of Sports Medicine published the most articles (n = 21, 42.0%). The most studied topic was concussion/traumatic brain injury (n = 18) followed by studies assessing all injuries (n = 7). Collegiate-level lacrosse was the most studied level of competition (n = 22), while high school-level followed (n = 12). CONCLUSIONS: The majority of the 50 most-cited articles related to lacrosse since 1990 focus on the prevalence, diagnosis and identification of concussion/traumatic brain injury in high school and collegiate-level athletes. These articles are predominantly epidemiological or cohort studies with Level III or IV evidence that almost unanimously originate from the United States.

Objective There are few studies to date reporting on outcomes following reverse total shoulder arthroplasty with cohorts stratified by glenosphere size. The purpose of this study is to investigate the role that glenosphere size has on postoperative outcomes. Methods Patients who underwent reverse TSA between 1987 with minimum of 2.0 years of follow-up were included. Patients were stratified into two cohorts based on glenosphere size of 36mm or 40mm. Patients' range of motion, patient-reported outcomes, and radiographic variables (glenoid preoperative morphology, scapular notching, humeral loosening) were evaluated. Results All measurements of range of motion measurements with the exception of internal rotation saw significant preoperative to postoperative improvements within each cohort. There were no significant differences in postoperative range of motion, ASES, or VAS pain scores across the two cohorts. Overall, forward elevation improved to 134° ± 16° in the 36mm cohort and 133° ± 14° in the 40mm cohort ( p = 0.47). External rotation improved to 37° ± 13° for 36mm patients and 35° ± 19° for 40mm patients ( p = 0.58). In the 36mm group, internal rotation increased by 1.3 vertebral levels and 2.3 vertebral levels in the 40mm cohort. At final follow-up, the 36mm cohort had a VAS score of 2 ± 2, ASES score of 66 ± 19, and SST score of 6 ± 3. Similarly, the 40mm cohort had a VAS score of 2 ± 3, ASES score of 77 ± 28, and SST score of 9 ± 3. Conclusions Reverse TSA provides sustained improvements in range of motion and shoulder function irrespective of glenosphere size. Level of Evidence III.
RESUMO
Objective To investigate whether patients undergoing anatomic total shoulder arthroplasty (ATSA) between January and March 2020 experienced different postoperative outcomes than patients in 2019. We hypothesized that patients in 2020 would have less access to physical therapy (PT) and experience different postoperative outcomes. Methods Records from patients who received ATSA between January 1st, 2019, and March 17th, 2019, and January 1st, 2020, to March 17th, 2020, were analyzed. Patient data, including demographic information, range of motion (ROM), strength, and PT was collected and compared between the two groups. The 2020 patients were contacted by phone during October 2022 and patient-reported metrics were gathered. Results The present study identified 24 patients in 2019 and 27 patients in 2020 who underwent ATSA during the specified time frame and had a minimum 1-year follow-up. Patients in 2019 experienced improvements in forward elevation (FE) ROM (125.4° to 146.7°; p = 0.008), external rotation (ER; 33.0° to 47.7°; p < 0.001), and internal rotation (IR; S1 to L4; p = 0.019). Patients in 2020 also experienced significant improvements in FE (120.2° to 141.1°; p = 0.009), ER (32.9° to 42.0°; p = 0.037), and IR (S1 to L3; p = 0.002). Patients in 2020 terminated PT earlier (2019: 125.8 days; 2020: 91.1 days; p = 0.046) and completed fewer sessions (2019: 21.4 sessions; 2020: 13.1 sessions; p = 0.003). At the final follow-up, patients in 2020 reported an average Visual Analogue Scale (VAS) pain score of 1.67 ± 1.1. Conclusion Despite decreased PT, patients who underwent ATSA in 2020 had significant improvements in ROM and strength and were comparable to patients in 2019.
RESUMO
Background: Revision shoulder arthroplasty (SA) is a surgical procedure performed to address complications or failures of primary total SA. However, limited evidence exists regarding the functional outcomes and longevity of implants following revision. Methods: A retrospective analysis was conducted on patients who underwent revision SA for failed primary arthroplasty at a single institution between 2009 and 2021 with a minimum of 2-years follow-up. Data was collected from medical records, including type of arthroplasty (anatomic total SA [TSA], reverse total SA [RSA], or hemi-SA [HSA]), demographics and patient-specific information, functional measurements, and implant survival. Patient reported outcomes were obtained during follow-up by phone. Results: The mean age at index and revision surgeries was 60.5 ± 12.1 years and 64.8 ± 11.1 years, respectively, and average total follow-up was 5.5 ± 3.5 years. The average time to revision was 4.5 ± 5.2 years (range 0.01-24.5 years). Among 99 revision shoulder arthroplasty procedures, 28 were TSA/HA to TSA/HA, 51 were TSA/HA to RSA, 18 were RSA to RSA, and 2 were RSA to HA. Revision surgery significantly improved functional outcomes in forward elevation (preoperative: 79.8 ± 41.0 vs postoperative: 118.5 ± 38.3; p < 0.001), external rotation (preoperative: 27.8 ± 19.3 vs postoperative: 34.3 ± 16.2; p = 0.028), internal rotation (preoperative: glute vs postoperative: S1; p = 0.002), and forward elevation strength (preoperative: 4+/5 vs postoperative: 5/5; p = 0.002). Postoperative patient reported outcomes included: VAS pain (2.2 ± 2.9), SANE (72.6 ± 21.5), ASES (73.3 ± 20.4), and SST (7.7 ± 2.8) scores. The overall 2-, 5-, and 10-year post-revision implant survival rate was 85.48%, 83.06%, and 79.84%, respectively. Patients who had an initial RSA and were revised to RSA were at higher risk of implant failure and subsequent re-revision (RSA to RSA: 1.5 ± 2.5 years vs. TSA/HA to RSA: 2.5 ± 2.1 years vs. TSA/HA to TSA/HA: 4.0 ± 3.5 years; p = 0.0046). Conclusion: Revision shoulder arthroplasty improved patient outcomes post-index arthroplasty failure. Revisions were more likely to be successful when revising from TSA/HA to RSA. Level of evidence: Level III - retrospective comparative study.
RESUMO
CASE: A 27-year-old woman developed capitellar osteonecrosis after long-term corticosteroid use to treat non-Hodgkin lymphoma. She underwent an osteochondral reconstruction using a lateral femoral condyle (LFC) allograft. This graft was selected because it has a similar radius of curvature to the capitellum. The patient had osseous integration, painless, near full range of motion of her elbow 6 months postoperatively and good shoulder function 1.0 year postoperatively. CONCLUSION: The LFC allograft should be considered a viable option in treating capitellar osteonecrosis.

Background: As total shoulder arthroplasty (TSA) expands to younger patients, it is crucial to weigh the benefits of early intervention against potential complications and implant longevity in patients under 60 years of age. This study examines mid-term outcomes in this patient subset. Methods: Between 2009 and 2019, a retrospective analysis was conducted on 50 patients (25 male, 25 female) who underwent anatomic TSA (TSA) under the age of 60 with minimum 5 years follow-up. Demographic and baseline variables were extracted from medical records. Pre-operative and post-operative outcomes of range of motion (ROM) and strength were recorded. Patient-reported outcomes (PROs) were obtained. Results: Fifty patients were followed for an average of 8.7 ± 2.4 years, having a mean age of 54.1 ± 8.4 years. Comparison of pre-operative and post-operative measurements revealed significant improvements in active ROM, including external rotation (ER) (p < 0.0001), forward elevation (FE) (p < 0.0001), and internal rotation (IR) (p = 0.0001). There were significant improvements in functional strength scores, including ER (p = 0.0005) and FE (p = 0.0002). PROs included visual analog scale (VAS) (2.2 ± 2.6), Single Assessment Numeric Evaluation (SANE) (80.3 ± 17.6), American Shoulder and Elbow Surgeons (ASES) score (76.4 ± 22.8), and Simple Shoulder Test (SST) (8.9 ± 3.2). The 5-year and 10-year implant survival rates were found to be 98.0 % and 83.3 %, respectively. There were 7 postoperative complications in 5 patients (14.0 %), including glenoid loosening (n = 2), infection (n = 1), atraumatic instability (n = 1), lesser tuberosity avulsion (n = 1), painful arthroplasty (n = 1) and traumatic rotator cuff insufficiency (n = 1). Subsequently, all 5 patients underwent revision shoulder arthroplasty at an average of 6.5 years after the initial procedure. Conclusion: Positive mid to long-term outcomes, including significant improvements in ROM and strength, along with high 5-year and 10-year implant survival rates support TSA as an effective treatment option for patients under the age of 60.
RESUMO
Objective Shoulder pain is a common presentation in the primary care setting, and shoulder pain after vaccination has a growing body of literature. The present study sought to understand how a standardized treatment protocol would aid patients experiencing shoulder injury related to vaccine administration (SIRVA). Methods Patients experiencing SIRVA were retrospectively recruited between February 2017 and February 2021. All patients were treated with physical therapy and offered a cortisone injection. Post-treatment range of motion (i.e., forward elevation, external rotation, internal rotation) and patients' reported outcomes were collected with the visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES), simple shoulder test (SST), and single assessment numeric evaluation (SANE) scores. Results A total of 9 patients were retrospectively examined. Among them, 6 patients presented within one month of a recent vaccination event, while 3 patients presented 67, 87, and 120 days after vaccination. Furthermore, 8 of the patients completed physical therapy, and 6 of them underwent a cortisone injection. The follow-up time averaged 8 months. At final follow-up, the mean external rotation was 61° (standard deviation, SD ± 3°) and the mean forward elevation was 179° (SD ± 45°). Internal rotation ranged between L3 and T10. The VAS pain scores were 3.5/10.0 (SD ± 2.4), the mean ASES score was 63.5/100.0 (SD ± 26.3), and the SST scores were 8.5/12.0 (SD ± 3.9). Finally, the SANE scores were 75.7/100.0 (SD ± 24.7) and 95.7/100.0 (SD ± 6.1) in the injured and contralateral shoulders respectively. Conclusion Shoulder pain after a vaccination treated with physical therapy and cortisone injection ultimately resulted in favorable shoulder range of motion and functional score outcomes. Level of Evidence IV.
