ABSTRACT
BACKGROUND: Pulmonary Hypertension (PH) frequently complicates the evaluation of kidney transplant (KT) candidates, and is associated with increased adverse outcomes (mortality, delayed graft function (DGF), and major adverse cardiovascular events (MACE)) following KT. RESEARCH QUESTION: What is the relationship between cardiopulmonary hemodynamics and post-KT outcomes? STUDY DESIGN AND METHODS: We conducted a multicenter retrospective cohort study of adults undergoing KT between 10/1/11 and 10/1/21, who underwent right heart catheterization (RHC) to assess cardiopulmonary hemodynamics within a year of transplantation. Frailty models and logistic regression models were used to evaluate the association between cardiopulmonary hemodynamics and outcomes (mortality, DGF, MACE) following KT. RESULTS: A total of 117 patients were included in the final analysis, predominantly male (72%), with a median age of 57 years. PH, defined as mean pulmonary artery pressure (mPAP) > 20mmHg, was present in the majority of the cohort (N=93, 79%). The cohort was followed for a median of 29.9 months post-KT, during which about one-fourth experienced mortality (23%) or DGF (25%) events, and approximately one-third (34%) experienced MACE. Though echocardiographic measures of pulmonary artery pressure failed to identify post-KT outcomes, a mPAP of ≥ 30mmHg on RHC was associated with post-KT MACE (Hazard Ratio 2.60, 95% Confidence Interval [1.10, 6.10]) and more prevalent in those experiencing post-KT mortality (63% vs 32%, p=0.001). Pre-capillary pulmonary hypertension was also associated with post-KT mortality (Hazard Ratio 3.71, 95% Confidence Interval [1.07, 12.90]). INTERPRETATION: Pre-capillary pulmonary hypertension and a mPAP of ≥ 30mmHg on RHC, but not echocardiographic evidence of PH, was associated with mortality and MACE following KT. These data suggest that RHC hemodynamics are superior to echocardiographic measures of PH in associating with outcomes following KT, and RHC-derived mPAP in particular may have value in predicting MACE and mortality post-KT.
ABSTRACT
Background: Several studies have examined return to play (RTP) and outcomes following the Latarjet procedure in contact athletes. Purpose: To investigate clinical outcomes affecting RTP following the Latarjet procedure in contact athletes. Study Design: Case series; Level of evidence, 4. Methods: A total of 67 contact athletes (72 shoulders) ≤35 years old who underwent Latarjet procedure for recurrent shoulder instability between January 1, 2018, and March 31, 2022, were retrospectively identified. Demographic information, medical history, surgical history, number of dislocations before surgery, and postoperative complications up to 6 months after surgery were reviewed. Outcomes evaluated included RTP, competition level, satisfaction, and patient-reported outcomes including visual analog scale for pain, American Shoulder and Elbow Surgeons (ASES) Score, and Disabilities of the Arm, Shoulder and Hand (DASH) scores. Results: There were a total of 67 patients (72 shoulders) included in the study with a mean age at surgery of 19.7 years for all shoulders. Of the total cohort, 46 patients (50 shoulders; [69.4%]) were available for follow-up by phone. Of the 46 patients contacted by phone, 22/46 were football players; 30/50 [60.0% of all shoulders]) were contact athletes and 19/46 [41.3%] limited contact athletes) were interviewed with a mean follow-up of 25.5 months (range, 10-49 months). Of 72 patients, 22 (30.6% of shoulders and 32.8% of patients) patients had prior shoulder surgery, most commonly arthroscopic stabilization. Only 1 patient experienced hardware failure, but this did not require reoperation. Sixteen of 46 (35%) athletes competed at the collegiate level, and 24/46 (52%) were high school athletes at the time of surgery; 34 of 46 patients (74%) returned to play, of which 30 of the 34 (88%) returned to playing at the same competition level; 15 of 22 (68%) football players returned to play. Only 4 of 51 (8%) reported subjective recurrent instability. Postoperative mean ASES score was 92.2, DASH score was 5.6, and visual analog scale for pain score was 4 (range, 0-50). A total of 43 of 46 (93%) patients reported improvement in quality of life after undergoing the Latarjet procedure for shoulder instability. Eight of 72 (11.1%) shoulders had unresolved pain or stiffness 6 months postoperatively, and 2 of 72 (2.8%) required revisions. Conclusion: Patient RTP, outcomes, and satisfaction were high following the Latarjet procedure in young contact athletes.
ABSTRACT
BACKGROUND: 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, multi-surgeon retrospective case-control study investigating the functional and patient reported outcomes of shoulder arthroplasty after SOT was conducted between the years of 2010-2020. 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 who only underwent arthroplasty. The primary outcomes include range of motion (ROM) 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 two cohorts, but within each cohort, improvement was statistically significant. In the SOT patients, forward elevation improved by 56o ± 52o, external rotation increased 13o ± 20o, and internal rotation increased by two vertebral levels. In the non-SOT patients, forward elevation improved 45o ± 51o, external rotation increased 16o ± 25o, and internal rotation increased by three vertebral levels. SOT patients had equivocal VAS pain and Simple Shoulder Test scores but lower ASES (59 ± 13 vs 79 ± 2; p=0.002) and SANE (61 ± 30 vs 84 ± 17; p<.001) scores than non-SOT patients. Complication rates were significantly higher in the SOT group (15% vs 6%; p=0.05), but incidence of surgical revisions was not significantly different (SOT = 3%; non-SOT = 5%; p=0.59). 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.
ABSTRACT
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.
ABSTRACT
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 Objetivo Investigar se os pacientes submetidos à artroplastia total anatômica do ombro (ATAO) entre janeiro e março de 2020 tiveram resultados pós-operatórios diferentes dos pacientes operados em 2019. Nossa hipótese é a de que os pacientes de 2020 teriam menos acesso à fisioterapia (FT) e apresentariam desfechos pós-opera-tórios diferentes. Métodos Foram analisados os prontuários de pacientes submetidos à ATAO de 1° de janeiro de 2019 a 17 de março de 2019 e de 1° de janeiro de 2020 a 17 de março de 2020. Os dados dos pacientes, incluindo informações demográficas, amplitude de movimento (ADM), força e FT foram coletados e comparados entre os dois grupos. Os pacientes de 2020 foram contatados por telefone durante outubro de 2022, e as métricas relatadas por eles pacientes foram coletadas. Resultados Este estudo identificou 24 pacientes em 2019 e 27 pacientes em 2020 que foram submetidos à ATAO durante o período especificado e tiveram acompanhamento mínimo de 1 ano. Os pacientes em 2019 apresentaram melhoras na ADM de elevação anterior (EA; 125,4° a 146,7°; p = 0,008), rotação externa (RE; 33,0° a 47,7°; p < 0,001) e rotação interna (RI; S1 a L4; p = 0,019). Os pacientes em 2020 também apresentaram melhoras significativas de EA (120,2° a 141,1°; p = 0,009), RE (32,9° a 42,0°; p = 0,037) e RI (S1 a L3; p = 0,002). Os pacientes de 2020 terminaram a FT mais cedo (2019: 125,8 dias; 2020: 91,1 dias; p = 0,046) e fizeram menos sessões (2019: 21,4 sessões; 2020: 13,1 sessões; p = 0,003). No acompanhamento final, os pacientes de 2020 relataram uma pontuação média de dor na Escala Visual Analógica (EVA) de 1,67 ± 1,1. Conclusão Apesar da menor realização de FT, os pacientes submetidos à ATAO em 2020 apresentaram melhoras significativas na ADM e na força e foram comparáveis aos pacientes de 2019.
ABSTRACT
BACKGROUND: Walch B2 glenoids can present a challenge to shoulder arthroplasty surgeons. Short-term studies have demonstrated that corrective reaming to 10° of retroversion in anatomic total shoulder arthroplasty (aTSA) can result in good outcomes; however, there is little data reporting the long-term outcomes in this cohort. B2 glenoids treated with high-side reaming present a theoretical risk of early glenoid component failure as one may ream into the subchondral bone. This study aimed to demonstrate that (1) B2 glenoids treated with corrective reaming have durable results and (2) offer similar results to Walch A1/2 in long-term follow-up. METHODS: Patients who underwent aTSA by a single surgeon (E.L.F.) were identified from a shoulder arthroplasty registry. Inclusion criteria included Walch A1, A2, or B2 glenoid; a diagnosis of primary shoulder osteoarthritis; and a minimum radiographic and clinical follow-up of 5 years. Forty-three patients with B2 glenoids were compared to a cohort of 42 patients with A1 or A2 glenoids. Preoperative computed tomography (CT) and radiographs were used to assess deformity, glenoid version, and posterior subluxation of the humeral head. Postoperatively, patients were assessed with radiographs and patient-reported outcome measures including American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score, Simple Shoulder Test (SST) score, and visual analog scale (VAS). RESULTS: Eighty-five shoulders (82 patients, 42 B2 and 43 A1/A2 glenoids) with an average follow-up of 9.4 years were included. In the B2 cohort, the average retroversion was 21.1° and posterior subluxation was 69.4% compared with 10.6° (P < .001) and 57.5% (P < .001), respectively, in the A1 or A2 cohort. The cohort demographics were similar except for male sex (B2 69.8% vs. A1 or A2 37.2%, P = .008). There was no difference between the cohorts in their improvement in ASES (P = .807), SST (P = .586), and VAS (P = .930) scores. There was no difference in lateral humeral offset (P = .889) or acromial humeral interval (P = .468) between initial postoperative and final follow-up visits. Survivorship for B2 glenoids was 97.6%, 94.1%, and 73.3% at 5, 10, and 15 years, respectively, compared with 97.6%, 91.9%, and 83.5% in type A glenoids. The revision rate was similar between the 2 groups (P = .432). Lazarus score (P = .682) and rates of humeral radiolucency (P = .366) and humeral osteolysis (P = .194) were similar between the 2 cohorts at final follow-up. CONCLUSION: Asymmetric reaming of patients with B2 glenoids is a reliable method of glenoid preparation with excellent mid- to long-term clinical results, patient-reported outcomes, and low revision rates similar to their A1 and A2 counterparts.
ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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.

OBJECTIVES: We sought to describe outcomes for locally advanced cutaneous squamous cell carcinoma (SCC) involving the parotid treated with volumetric modulated arc therapy (VMAT) versus pencil beam scanning proton beam therapy (PBT). MATERIALS AND METHODS: Patients were gathered from 2016 to 2022 from 5 sites of a large academic RT department; included patients were treated with RT and had parotid involvement by: direct extension of a cutaneous primary, parotid regional spread from a previously or contemporaneously resected but geographically separate cutaneous primary, or else primary parotid SCC (with a cutaneous primary ostensibly occult). Acute toxicities were provider-reported (CTCAE v5.0) and graded at each on treatment visit. Statistical analyses were conducted. RESULTS: Median follow-up was 12.9 months (1.3 - 72.8); 67 patients were included. Positive margins/extranodal extension were present in 34 cases; gross disease in 17. RT types: 39 (58.2 %) VMAT and 28 (41.8 %) PBT. Concurrent systemic therapy was delivered in 10 (14.9 %) patients. There were 17 treatment failures (25.4 %), median time of 168 days. Pathologically positive neck nodes were associated with locoregional recurrence (p = 0.015). Oral cavity, pharyngeal constrictor, and contralateral parotid doses were all significantly lower for PBT. Median weight change was -3.8 kg (-14.1 - 5.1) for VMAT and -3 kg (-16.8 - 3) for PBT (p = 0.013). Lower rates of ≥ grade 1 xerostomia (p = 0.002) and ≥ grade 1 dysguesia (p < 0.001) were demonstrated with PBT. CONCLUSIONS: Cutaneous SCC involving the parotid can be an aggressive clinical entity despite modern multimodal therapy. PBT offers significantly lower dose to organs at risk compared to VMAT, which seemingly yields diminished acute toxicities.

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.

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.
ABSTRACT
Background/aims: Understanding the factors that lead to poor outcomes after reverse total shoulder arthroplasty (rTSA) is important to appropriate patient counseling. While patient-reported allergies (PRAs) have been shown to be associated with poorer outcomes after both TKA and THA, their effect on rTSA outcomes remains unclear. This study investigated the effect of zero, one, and two or more preoperative PRAs on clinical outcomes after rTSA at over two years follow-up in a cohort of fifty-two patients from our institution. Methods: Patients who underwent rTSA and had a minimum follow-up time of two years were identified from an institutional database. Patients were split into cohorts of zero, one, and two or more PRAs. Range of motion (ROM) was assessed by degrees of forward elevation, external rotation, and internal rotation. Patient-reported outcomes (PROs) were assessed by the Visual Analog Scale (VAS), American Shoulder and Elbow Surgeon (ASES) score, and Simple Shoulder Test (SST) score. Results: Fifty-two patients, 10 of whom reported one allergy and 11 of whom reported two or more allergies, were included in our analysis. Mean ROM and PROs improved after rTSA in each cohort. Differences in ROM and PROs between cohorts did not reach statistical significance; however, patients with PRAs tended to have worse preoperative forward elevation, VAS score, and ASES score. Two patients in the zero-allergy cohort required revision (6 %). Conclusion: This study found no statistically significant difference in clinical outcomes among cohorts of patients with zero, one, or two or more preoperative PRAs after rTSA at over two years follow-up. However, patients with PRAs tended to have lower preoperative functional scores. We postulate that this may be the result of psychosomatic factors at play in these patients. PRAs should not dissuade patients or clinicians from pursuing rTSA.
ABSTRACT
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.

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.
ABSTRACT
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.

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.

STUDY DESIGN: Retrospective analysis. OBJECTIVE: To assess perioperative complication rates and readmission rates after ACDF in a patient population of advanced age. SUMMARY OF BACKGROUND DATA: Readmission rates after ACDF are important markers of surgical quality and, with recent shifts in reimbursement schedules, they are rapidly gaining weight in the determination of surgeon and hospital reimbursement. METHODS: Patients 18 years of age and older who underwent elective single-level ACDF were identified in the National Readmissions Database (NRD) and stratified into 4 cohorts: 18-39 ("young"), 40-64 ("middle"), 65-74 ("senior"), and 75+ ("elderly") years of age. For each cohort, the perioperative complications, frequency of those complications, and number of patients with at least 1 readmission within 30 and 90 days of discharge were analyzed. χ 2 tests were used to calculate likelihood of complications and readmissions. RESULTS: There were 1174 "elderly" patients in 2016, 1072 in 2017, and 1010 in 2018 who underwent ACDF. Their rate of any complication was 8.95%, 11.00%, and 13.47%, respectively ( P <0.0001), with dysphagia and acute posthemorrhagic anemia being the most common across all 3 years. They experienced complications at a greater frequency than their younger counterparts (15.80%, P <0.0001; 16.98%, P <0.0001; 21.68%, P <0.0001). They also required 30-day and 90-day readmission more frequently ( P <0.0001). CONCLUSION: It has been well-established that advanced patient age brings greater risk of perioperative complications in ACDF surgery. What remains unsettled is the characterization of this age-complication relationship within specific age cohorts and how these complications inform patient hospital course. Our study provides an updated analysis of age-specific complications and readmission rates in ACDF patients. Orthopedic surgeons may account for the rise in complication and readmission rates in this population with the corresponding reduction in length and stay and consider this relationship before discharging elderly ACDF patients.

Abstract 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 Objetivo Até agora, poucos estudos relataram os desfechos da artroplastia total reversa (ATR) de ombro com coortes estratificadas pelo tamanho da glenosfera. O objetivo deste estudo é investigar o papel do tamanho da glenosfera nos desfechos pós-operatórios. Métodos O estudo incluiu pacientes submetidos à ATR de ombro desde 1987 com acompanhamento mínimo de 2,0 anos. Os pacientes foram estratificados em duas coortes com base no tamanho da glenosfera (36 mm ou 40 mm). A amplitude de movimento, os desfechos relatados pelo paciente e as variáveis radiográficas (morfologia pré-operatória da glenoide, incisura escapular e instabilidade do úmero) foram avaliados. Resultados Todas as medidas de amplitude de movimento, à exceção da rotação interna, melhoraram de forma significativa entre o período pré-operatório e pós-operatório nas duas coortes. Não houve diferenças significativas na amplitude de movimento pós-operatória, pontuação da American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) ou escala visual analógica (EVA) de dor entre as duas coortes. De modo geral, a elevação anterior melhorou para 134° ± 16° na coorte de 36 mm e 133° ± 14° na coorte de 40 mm (p = 0,47). A rotação externa melhorou para 37° ± 13° em pacientes da coorte de 36 mm e 35° ± 19° em pacientes da coorte de 40 mm (p = 0,58). A rotação interna aumentou 1,3 níveis vertebrais na coorte de 36 mm e 2,3 níveis vertebrais na coorte de 40 mm. No último acompanhamento, a coorte de 36 mm apresentou EVA de 2 ± 2, ASES de 66 ± 19 e pontuação do Simple Shoulder Test (SST) de 6 ± 3. Da mesma forma, a coorte de 40 mm teve EVA de 2 ± 3, ASES de 77 ± 28 e SST de 9 ± 3. Conclusões A ATR de ombro causa melhoras sustentadas da amplitude de movimento e função articular independentemente do tamanho da glenosfera. Nível de Evidência III.
