Clinical outcomes and direct cost analysis of rotator cuff repair surgery.

OBJECTIVE: The purpose of this study was to evaluate the clinical and functional outcomes in patients who underwent surgical treatment for rotator cuff tears using open and arthroscopic techniques, and to evaluate the direct costs involved. METHODS: Retrospective cohort study with analysis of the data of patients who were referred to two private hospitals in Sao Paulo, Brazil for surgical repair of the rotator cuff from January 2018 to September 2019. Clinical outcomes were assessed using functional scores (SPADI and QuickDASH) and a quality of life questionnaire (EuroQoL). Procedure costs were calculated relative to each hospital's costliest procedure. RESULTS: Data from 362 patients were analyzed. The mean patient age was 57 years (SD= 10.46), with a slight male predominance (53.9%). Arthroscopic procedures were more common than open procedures (95.6% versus 4.4%). Significant clinical improvement was reported in 84.8% of the patients. The factors associated with increased surgery costs were arthroscopic technique (increase of 29.2%), age (increase of 0.6% per year), and length of stay (increase of 18.9% per day of hospitalization). CONCLUSION: Rotator cuff repair surgery is a highly effective procedure, associated with favorable clinical outcomes and improvement in life quality, and low rates of complications. Arthroscopic surgery tends to be costlier than open surgery.

Incidence and risk factors for shoulder stiffness after open and arthroscopic rotator cuff repair.

INTRODUCTION: The aim of this study was to estimate the incidence of stiffness during the first 6 months after rotator cuff repair and to evaluate postoperative stiffness with respect to its risk factors and its influence on the outcome at 6 months postoperatively. METHODS: In a prospective cohort of 117 patients (69 women, 48 men; average age 59) from our institutional rotator cuff registry, who underwent either arthroscopic (n = 77) or open (n = 40) rotator cuff repair, we measured shoulder range of motion (ROM) at 3 and 6 months post-surgery. We evaluated the incidence of stiffness and analyzed functional outcomes, comparing various preoperative and intraoperative factors in patients with stiffness to those without at the 6-month mark. RESULTS: Shoulder stiffness was observed in 31% of patients (36/117) at 3 months postoperatively, decreasing to 20% (23/117) at 6 months. No significant link was found between stiffness at 6 months and demographic factors, preoperative stiffness, tear characteristics, or the type of repair. Notably, patients undergoing arthroscopic repair exhibited a 4.3-fold higher risk (OR 4.3; 95% CI 1.2-15.6, p = 0.02) of developing stiffness at 6 months compared to those with mini-open repair. Despite these differences in stiffness rates, no significant variation was seen in the American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, or Visual Analog Scale (VAS) scores at 6 months between the groups. CONCLUSION: The incidence of postoperative shoulder stiffness following rotator cuff repair was substantial at 31% at 3 months, reducing to 20% by 6 months. Mini-open repair was associated with a lower 6-month stiffness incidence than arthroscopic repair, likely due to variations in rehabilitation protocols. However, the presence of stiffness at 6 months post-surgery did not significantly affect functional outcomes or pain levels.

Leukocyte-Poor Platelet-Rich Plasma as an Adjuvant to Arthroscopic Rotator Cuff Repair Reduces the Retear Rate But Does Not Improve Functional Outcomes: A Double-Blind Randomized Controlled Trial.

BACKGROUND: Whether the use of PRP as an adjuvant of rotator cuff repairs leads to improved tendon healing and better functional outcomes remains unclear in clinical evidence. PURPOSE: The main purpose of this study was to assess whether the use of leukocyte-poor platelet-rich plasma (LP-PRP) as an adjuvant to arthroscopic rotator cuff repair (ARCR) decreases the rate of retears compared with a control group. The secondary objective was to analyze whether LP-PRP improves patient-reported outcomes. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: This was a double-blind randomized controlled trial at a single center. A consecutive series of 96 patients with rotator cuff tears <3 cm were enrolled and randomly allocated to the control group (double-row suture-bridge ARCR alone [n = 48]) and the PRP group (double-row suture-bridge repair, followed by 1 LP-PRP injection during surgery [n = 48]). The visual analog scale (VAS) for pain, the American Shoulder and Elbow Surgeons (ASES) score, the Single Assessment Numeric Evaluation (SANE), and the Pittsburgh Sleep Quality Index (PSQI) were administered preoperatively and at 6- and 12-month follow-up. Magnetic resonance imaging (MRI) was performed to evaluate tendon integrity at 6-month follow-up. Both patients and assessors were blinded to the intervention received during surgery. RESULTS: The mean patient age was 56.1 ± 2.98 years. Of the 96 patients, 90 had MRI performed at 6 months after surgery (94% radiological follow-up). The retear rate in the PRP group was 15.2% (7/46 [95% CI, 6%-28%]), which was lower than that in the control group of 34.1% (15/44 [95% CI, 20%-49%]) (P = .037). Therefore, the risk ratio of ruptures in patients exposed to LP-PRP was 0.44 (95% CI, 0.2-0.9; P = .037). Overall, the ASES, VAS, SANE, and PSQI scores showed a statistical improvement after surgery (P < .001). There were no significant differences in functional scores between the groups. Most of the patients exceeded the minimal clinically important difference for the ASES, SANE, and VAS without significant differences between the groups. CONCLUSION: In patients with rotator cuff tears <3 cm undergoing double-row suture-bridge repair, a 5-mL dose of LP-PRP injected at the tendon-bone interface significantly reduced the retear rate. However, the use of LP-PRP in terms of postoperative pain and patient-reported outcomes failed to show clinically meaningful effects. REGISTRATION: NCT04703998 (ClinicalTrials.gov identifier).

Outcome of reverse shoulder arthroplasty secondary to rotator cuff arthropathy in a low-income population.

BACKGROUND: Reverse shoulder arthroplasty (RSA) is a valuable treatment for rotator cuff arthropathy (RCA) in developed regions. Socioeconomic issues impact access to specialized care and there is a lack of data on RSA outcomes in developing regions. We present our 24-month follow-up on RSA surgeries to treat RCA in our low-income population. METHODS: Prospective evaluation of 26 patients subjected to RSA at Hospital Geral de Fortaleza-CE, Brazil, between January 2018 and December 2020. Literacy [>/≤ 8 school years(SY)] and income were documented. Outcomes considered pain (visual analogue scale; VAS) as well as SSV, SPADI, ASES, and UCLA scoring, and range of motion [forward flexion (FF); external rotation (ER)]. RESULTS: Patients were 68.5 ± 7.6 years-old with 16(61.5%) females; 65% had hypertension and 7 (26.9%) had diabetes. Over 90% declared < 900.00 US$ monthly family earnings and 10 (38.4%) patients declared ≤8 SY with > 80% exerting blue-collar jobs. Pain showed a significant reduction from baseline (8 ± 2) to 24 months (2.1 ± 2.3; p < 0.001). UCLA (10.3 ± 5.6 and 28.6 ± 7.2), ASES (16.7 ± 10.8 and 63.1 ± 28.4), SSV (326 ± 311 and 760 ± 234), and SPADI (98.3 ± 26.5) scores significantly improved from baseline to 24 months, achieving minimal clinically important difference. FF (89.2° ± 51.2° to 140.6 ± 38.3°) and ER (19.2° ± 22.5 to 33.4° ± 20.6°) significantly improved from baseline to 24 months (p = 0.004 and 0.027, respectively). There were 5 non-serious adverse events with one surgical revision. All patients returned to daily life activities. CONCLUSION: This is the first outcome report 2 years following RSA in a low-income population. Data indicate this procedure is justifiable regardless of socioeconomic issues.

Multimodal postoperative analgesia with transdermal buprenorphine is a safe option in arthroscopic rotator cuff repair.

BACKGROUND: Arthroscopic rotator cuff repairs are associated with moderate-to-severe pain. Opioids are not the first line for postsurgical pain control due to their potential misuse and side effects. Transdermal buprenorphine represents an alternative for multimodal postoperative pain control. METHODS: This was a single-centre, prospective longitudinal exploratory study of patients undergoing arthroscopic rotator cuff repairs managed with multimodal analgesia with transdermal buprenorphine. Patients were followed-up by telephone at eight time points, assessing pain levels, rescue analgesics requirement and side effects. FINDINGS: Twenty-five patients with an average age of 63.4 ± 8.2 were included. Fourteen patients were ⩾65 years. Pain levels were similar among age groups at all time points, with no pain or mild pain (visual analogue scale 1-4) in most patients. The most frequent side effects were dizziness and somnolence. CONCLUSION: Transdermal buprenorphine provided a sustained analgesic effect after an arthroscopic rotator cuff repair during the acute postsurgical period. It showed a similar safety profile among younger and older patients.

Rotator cuff repair and return to sports practice in athletes older than 35 years: Is it possible? A systematic review.

INTRODUCTION: Return to sport is an important measure of treatment success for athletes undergoing rotator cuff repair, which can be challenging in older athletes. The purpose of the present study was to systematically review and summarize the literature regarding the return to sport in athletes older than 35 years undergoing rotator cuff repair. MATERIALS AND METHODS: A systematic review of the literature was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The electronic databases of PubMed, MEDLINE, and Cochrane were used for the literature search. Studies in English evaluating return to sport after repair of partial- or full-thickness rotator cuff tears among athletes older than 35 years of all levels and sports were included. RESULTS: Four studies of level III and IV were included in this review, with a total of 140 athletes. Both full- and partial-thickness rotator cuff tears were described and managed via acromioplasty combined with open or arthroscopic repair using single or double-row suture. Of the 140 athletes, 122 returned to sports, with 102 returning to equal or higher level pre-injury. The lower mean time to return to sport among the studies included was 6.3 months. CONCLUSIONS: Although the evidence is limited, rotator cuff tear should not be seen as a mandatory reason for the retirement of older athletes. Of the 140 athletes included in this review, 122 returned to sport, with 102 returning to equal or higher level pre-injury.

Can Distalisation and Lateralisation Shoulder Angles in Reverse Arthroplasty Interfere with the Functional Results in Patients with Rotator Cuff Arthropathy? / Os ângulos de distalização e lateralização do ombro na artroplastia reversa podem interferir nos resultados funcionais em pacientes com artropatia do manguito rotador?

Abstract Objective: To evaluate the influence of radiographic values on clinical and functional results in patients treated with reverse arthroplasty for rotator cuff arthropathy (RCA) using a lateralized design. Methods: A retrospective analysis was performed. Patient demographics were recorded, as well as preoperative and postoperative range of motion. Function was calculated using the Constant-Murley score both before and after the procedure. Pre and postoperative anteroposterior and axial radiographs of the affected shoulder were analysed. In the preoperative images, the following was calculated: acromiohumeral distance (AHD) and lateral humeral offset (LHO). Postoperative measurements included: AHD, LHO, distalization shoulder angle (DSA) and lateralisation shoulder angle (LSA). Linear regression and quadratic regression analysis was performed to determine their degree of association with final functional outcomes. By applying a quadratic regression analysis and ROC curves, the cut-off values were determined with respect to the above-mentioned angles and the VPP was calculated. Results: The greater anterior elevation (AE) ranges were found with DSA between 40-45° and LSA among 80°- 90°, while better ABD was observed with LSA of 90-100°. Preoperative AHD was correlated to RE (rs:0.47; p:0.049). Postoperative AHD was found to be in a directly proportional relationship with AE (rs:0.49; p:0.03). Postoperative ABD showed an inverse linear regression with preoperative AHD (rs: -0.44, p:0.047). LSA and DSA were inversely related. Conclusion: We found that a DSA between 40-45° and a LSA of 80-100° could lead to better range of motion regarding AE and ABD in patients with rotator cuff arthropathy treated with RSA.

Resumo Objetivo: Avaliar a influência dos valores radiográficos nos resultados clínicos e funcionais em pacientes tratados com artroplastia reversa para artropatia do manguito rotador utilizando um desenho lateralizado. Métodos: Foi realizada uma análise retrospectiva. Foram registradas as demografias dos pacientes, bem como o intervalo de movimento pré-operatório e pós-operatório. A função foi calculada usando a pontuação Constant-Murley tanto antes como depois do procedimento. Radiografias pré e pós-operatórias anteroposteriores e axiais do ombro afetado foram analisadas. Nas imagens pré-operatórias, foram calculados a distância acromioumeral (DAU)e offset lateral umeral (OLU). As medidas pós-operatórias incluídas foram DAU, OLU, ângulo de distalização do ombro (ADO) e ângulo de lateralização do ombro (ALO). Foi realizada uma análise de regressão linear e regressão quadrática para determinar seu grau de associação com os resultados funcionais finais. Aplicando uma análise de regressão quadrática e curvas ROC, os valores de corte foram determinados em relação aos ângulos acima mencionados e o valor preditivo positivo foi calculado. Resultados: As maiores faixas de elevação anterior (EA) foram encontradas com ADO entre 40 e 45° e ALO entre 80 e 90°, enquanto a melhor abdução (ABD) foi observada com ALO de 90 e 100°. A DAU pré-operatória foi correlacionada com a rotação externa (RE) (rs: 0,47; p: 0,049). A DAU pós-operatória apresentou uma relação diretamente proporcional com a EA (rs: 0,49; p: 0,03). A ABD pós-operatória mostrou uma regressão linear inversa com a DAU pré-operatória (rs: -0,44, p: 0,047). O ALO e o ADO estavam inversamente relacionados. Conclusão: Determinamos que um ADO entre 40 e 45° e um ALO de 80 e 100° poderia levar a uma melhor amplitude de movimento em relação à EA e ABD em pacientes com artropatia do manguito rotador tratados com artroplastia reversa de ombro.

[Concordance between ultrasound-arthroscopy of the shoulder in rotator cuff injury]. / Concordancia entre ecografía-artroscopía de hombro en lesión del mango rotador.

Background: Rotator cuff injury occurs over tendons that insert into the humeral tuberosity. Ultrasonography detects the size and extent of tendon tears. Its sensitivity and specificity range from 91-100% and 85-86%, respectively. It has been shown that a trained orthopedic surgeon can perform shoulder ultrasonography for the accurate diagnosis of rotator cuff pathology. Objective: To determine the concordance between ultrasound-arthroscopy of the shoulder in rotator cuff injuries at the Unidad Médica Atención Ambulatoria No. 55 (Ambulatory Care Unit No. 55) in León, Guanajuato, Mexico. Material and methods: Experimental study of a sample of 37 patients with a diagnosis of rotator cuff injury, in whom preoperative ultrasound and later shoulder arthroscopy of the same side were performed. The data were subjected to concordance with Cohen's Kappa Index. Results: There were 37 patients in whom we identified an overall concordance of 81%. Cohen's Kappa index was 0.76, considered a good concordance. Out of the 7 patients without correlation, in 1 patient the ultrasound showed partial rupture and by arthroscopy showed complete rupture of the supraspinatus. In 2 patients ultrasonography showed complete rotator cuff tear; during arthroscopy, both showed massive rotator cuff tear. Conclusions: Preoperative shoulder ultrasonography performed by traumatology presents a good concordance in the diagnosis of rotator cuff tears confirmed by arthroscopy.

Introducción: la lesión del mango rotador ocurre sobre tendones que se insertan en la tuberosidad humeral. La ecografía detecta el tamaño y la extensión de los desgarros del tendón. Su sensibilidad y especificidad oscila entre 91-100% y 85-86%, respectivamente. Se ha demostrado que un cirujano ortopédico capacitado puede hacer la ecografía del hombro para el diagnóstico preciso de la patología del manguito rotador. Objetivo: determinar la concordancia entre ecografía-artroscopía de hombro en lesiones del mango rotador en la Unidad Médica Atención Ambulatoria No. 55 de León, Guanajuato, México. Material y métodos: estudio experimental de una muestra de 37 pacientes con diagnóstico de lesión del mango rotador, en los que se realizó ecografía preoperatoria y posteriormente artroscopía de hombro del mismo lado. Los datos se sometieron a concordancia con el Índice de Kappa de Cohen. Resultados: fueron 37 pacientes en los que se identificó la concordancia global de 81%. El Índice de Kappa de Cohen fue de 0.76, considerada una buena concordancia. De los 7 pacientes sin correlación, en un paciente la ecografía mostró rotura parcial y por artroscopía mostró rotura completa del supraespinoso. En 2 pacientes la ecografía mostró rotura completa de mango rotador; durante la artroscopía, ambos mostraron rotura masiva del mango rotador. Conclusiones: la ecografía preoperatoria de hombro realizada por traumatología presenta una buena concordancia en el diagnóstico de roturas del mango rotador confirmadas por artroscopía.

[Functional comparison between arthroscopy and open surgery for rotator cuff injuries]. / Comparativa funcional entre artroscopía y cirugía abierta para lesiones del mango rotador.

Background: Rotator cuff injuries result in impaired functionality of the shoulder. The difference in shoulder functionality in patients treated with arthroscopy who required open surgery is still unknown. Objective: To determine if there is a difference in the functional evolution of the shoulder in patients who underwent surgery due to rotator cuff lesion which began with arthroscopy and ended in open surgery. Material and methods: A cohort, longitudinal, observational and comparative study was carried out. The Constant scale was applied to measure the functionality of the shoulder in patients who underwent surgery due to rotator cuff injury, prior to surgery, 3 and 6 months after it, from August 2021 to April 2022. Functionality between patients who started with arthroscopy and required surgery and with those who only underwent arthroscopy was compared. Results: 30 patients were included. Shoulder functionality in the preoperative period had a mean of 42.2 ± 18 (95% confidence interval [95% CI] 35.5-49.0), at 3 months of 48.18 ± 14 (95% CI 42.9-53.4) and at 6 months of 66.7 (95% CI 60.1-73.4), with a p = 0.001. The difference between the patients who required surgery was not significant (p = 0.3). Conclusions: The functional evolution of the shoulder in patients who underwent surgery due to rotator cuff injury improves over time. The type of surgery does not influence the functional evolution.

Introducción: las lesiones del mango rotador ocasionan deterioro de la funcionalidad del hombro. La diferencia en la funcionalidad del hombro en pacientes tratados con artroscopía que ameritaron cirugía abierta aún se desconoce. Objetivo: determinar si existe diferencia en la evolución funcional del hombro en pacientes intervenidos por lesión del mango rotador que iniciaron con artroscopía y terminaron en cirugía abierta. Material y métodos: se hizo un estudio de cohorte, longitudinal, observacional y comparativo. Se aplicó la escala Constant para medir la funcionalidad del hombro en pacientes intervenidos por lesión del mango rotador, previo a la cirugía, a los 3 y a los 6 meses posteriores a esta, entre agosto de 2021 y abril de 2022. Se comparó la funcionalidad entre los pacientes que iniciaron con artroscopía y que requirieron cirugía con los que solo se intervinieron con artroscopía. Resultados: se incluyeron 30 pacientes. La funcionalidad del hombro en el preoperatorio tuvo una media de 42.2 ± 18 (intervalo de confianza del 95% [IC 95%] 35.5-49.0), a los 3 meses se obtuvo una media de 48.18±14 (IC 95% 42.9-53.4) y a los 6 meses de 66.7 (IC 95% 60.1-73.4), con una p = 0.001. La diferencia entre los pacientes que requirieron cirugía no fue significativa (p = 0.3). Conclusiones: la evolución funcional del hombro en pacientes intervenidos por lesión del mango rotador mejora con el paso del tiempo. El tipo de cirugía no influye en la evolución funcional.

[Results of the treatment of irreparable rotator cuff ruptures with the use of the subacromial balloon]. / Resultados del tratamiento de roturas irreparables de manguito rotador con el uso del balón subacromial.

INTRODUCTION: arthroscopic surgical treatment of rotator cuff tendon injuries has replaced open surgery as the first treatment option. Different surgical techniques have been described for massive or irreparable ruptures, and recently, a new device that consists of a biodegradable subacromial spacer between the humeral head and the acromion has been used. The present study aims to analyse the results of this implant in our experience. MATERIAL AND METHODS: we conducted an observational and retrospective study of all patients undergoing subacromial spacer implantation at our centre from 2017 to 2019. Patients were assessed pre- and postoperatively using the Constant, DASH and VAS scales. RESULTS: a total of 43 patients met the inclusion criteria and the minimum follow-up of 24 months. The mean DASH scale score went from 53.6 at preoperative assessment to 27.9 at postoperative assessment (p = 0.026). There was also a significant improvement in the Constant scale from a mean of 37.9 to 61.8 (p = 0.037). In terms of pain assessment, the mean VAS went from a mean of 7.44 to 3.38 (p = 0.916). In 90% of patients no complications or need for further interventions were objectified. CONCLUSIONS: the subacromial balloon has shown favorable results in our series of patients, so it could be a valid treatment option in patients with non-repairable rotator cuff tears.

INTRODUCCIÓN: el tratamiento mediante cirugía artroscópica de las lesiones del manguito rotador ha desplazado a la cirugía abierta como primera opción de tratamiento. Existen diferentes técnicas quirúrgicas descritas para tratar las roturas masivas o no reparables. Desde hace unos años se viene utilizando un nuevo dispositivo que consiste en un balón subacromial biodegradable que actúa como espaciador entre la cabeza humeral y el acromion. Este trabajo pretende analizar los resultados de este implante. MATERIAL Y MÉTODOS: realizamos un estudio observacional y retrospectivo de todos los pacientes a los que se les implantó un balón subacromial en nuestro centro entre 2017 y 2019. Se evaluó a los pacientes pre y postoperatoriamente mediante las escalas de Constant, DASH y EVA. RESULTADOS: un total de 43 pacientes cumplieron los criterios de inclusión y el seguimiento mínimo de 24 meses. La puntuación media de la escala DASH pasó de 53.6 en la evaluación preoperatoria a 27.9 en la postoperatoria (p = 0.026). También se obtuvo una mejoría significativa en la escala de Constant, que pasó de una media de 37.9 a 61.8 (p = 0.037). En cuanto a la evaluación del dolor, la EVA media pasó de 7.44 a 3.38 (p = 0.916). En 90% de los pacientes no se objetivaron complicaciones ni necesidad de nuevas intervenciones. CONCLUSIONES: el balón subacromial ha mostrado resultados favorables en nuestra serie de pacientes, por lo que podría suponer una opción válida de tratamiento en pacientes con roturas no reparables del manguito rotador.

The Impact of COVID-19 on the Timing of Rotator Cuff Repair and Method of Postoperative Follow-up / Impacto da COVID-19 no momento de reparo do manguito rotador e método de acompanhamento pós-operatório

Abstract Objective Rotator cuff repair (RCR) is one of the most common arthroscopic procedures. Our investigation aims to quantify the impact that the COVID-19 pandemic had on RCR, specifically on patients with acute, traumatic injuries. Methods Institutional records were queried to identify patients who underwent arthroscopic RCR between March 1st to October 31st of both 2019 and 2020. Patient demographic, preoperative, perioperative, and postoperative data were collected from electronic medical records. Inferential statistics were used to analyze data. Results Totals of 72 and of 60 patients were identified in 2019 and in 2020, respectively. Patients in 2019 experienced shorter lengths of time from MRI to surgery (62.7 ± 70.5 days versus 115.7 ± 151.0 days; p = 0.01). Magnetic resonance imaging (MRI) scans showed a smaller average degree of retraction in 2019 (2.1 ± 1.3 cm versus 2.6 ± 1.2 cm; p = 0.05) butnodifference in anterior toposterior tear size between years (1.6 ± 1.0 cm versus 1.8 ± 1.0 cm; p = 0.17). Less patients in 2019 had a tele-health postoperative consultation with their operating surgeon compared with 2020 (0.0% versus 10.0%; p = 0.009). No significant changes in complications (0.0% versus 0.0%; p > 0.999), readmission (0.0% versus 0.0%; p > 0.999), or revision rates (5.6% versus 0.0%; p = 0.13) were observed. Conclusion From 2019 to 2020, there were no significant differences in patient demographics or major comorbidities. Our data suggests that even though the time from MRI to surgery was delayed in 2020 and telemedicine appointments were necessary, RCR was still performed in a time in early complications. Level of Evidence III.

Nossapesquisavisaquantificar o impacto da pandemia de COVID-19 sobre o RMR, especificamente em pacientes com lesões agudas e traumáticas. Métodos Os prontuários institucionais foram consultados para identificação de pacientes submetidos ao RMR artroscópico entre 1° de março e 31 de outubro de 2019 e de 2020. Dados demográficos, pré-operatórios, perioperatórios e pós-operatórios dos pacientes foram coletados de prontuários eletrônicos. Os dados foram analisados por estatística inferencial. Resultados Totais de 72 ede60pacientes foramidentificados em 2019 e 2020, respectivamente. Os pacientes de 2019 apresentaram menor intervalo entre a ressonância magnética (RM) e a cirurgia (62,7 ± 70,5 dias versus 115,7 ± 151,0 dias; p = 0,01). Os exames de RM mostraram menor grau médio de retração em 2019 (2,1 ± 1,3 cm versus 2,6 ± 1,2 cm; p = 0,05), mas nenhuma diferença foi observada na extensão anteroposterior da laceração entre os anos (1,6 ± 1,0 cm versus 1,8 ± 1,0 cm; p = 0,17).Em 2019,o número de pacientes atendidos por seus cirurgiões em consultas pós-operatórias por telemedicina foi menor em comparação com 2020 (0,0% versus 10,0%; p = 0,009). Não foram observadas alterações significativas nas taxas de complicação (0,0% versus 0,0%; p > 0,999), de readmissão (0,0% versus 0,0%; p > 0,999) ou de revisão (5,6% versus 0,0%; p = 0,13). Conclusão Não houve diferenças significativas nos dados demográficos dos pacientes ou nas principais comorbidades entre 2019 e 2020. Nossos dados sugerem que, embora o intervalo entre a RM e a cirurgia tenha sido maior em 2020 e tenha havido necessidade de consultas por telemedicina, o RMR ainda foi realizado em tempo hábil e sem alterações significativas nas complicações precoces.

[Benefits of arthroscopic rotator cuff repair in octogenarians. Analysis of functional results and complications]. / Beneficios de la reparación artroscópica del manguito rotador en octogenarios. Análisis de resultados funcionales y complicaciones.

INTRODUCTION: There is a lack of information in the literature on the results of arthroscopic rotator cuff repair in patients older than 80 years. The purpose of this study was to evaluate a consecutive series of patients with rotator cuff tears who underwent arthroscopic rotator cuff repair. METHODS: Retrospective analysis of patients older than 80 years who underwent arthroscopic rotator cuff repair between June 2004 and January 2016. The minimum follow-up was 2 years. For functional and pain assessment, the Constant, Dash, UCLA scale and Visual Analogue Scale (VAS) for pain were used. RESULTS: The average follow-up was 8.4 years. Significant improvements were obtained in the assessment of the range of motion and the evaluation of the Constant, Dash and UCLA scales, as well as in the VAS. No major complications were recorded and only 4 patients required a reoperation. CONCLUSION: The main findings obtained were functional and pain improvement in patients over 80 years of age operated on for a complete arthroscopic rotator cuff tear.

Introducción: Existe falta de información en la literatura sobre los resultados de la reparación artroscópica del manguito rotador en pacientes mayores de 80 años. El objetivo de este estudio fue evaluar una serie consecutiva de pacientes con rupturas del manguito rotador a los que se les realizó la reparación artroscópica del mismo. Métodos: Análisis retrospectivo de pacientes mayores de 80 años a quienes se les realizó reparación artroscópica de manguito rotador entre junio de 2004 y enero de 2016. El seguimiento mínimo fue de 2 años. Para la evaluación funcional y del dolor se utilizaron las escalas Constant, Dash, UCLA y Escala Visual Análoga (EVA). Resultados: El seguimiento promedio fue de 8.4 años. Se obtuvieron mejoras significativas en la valoración del rango de movilidad y la evaluación de las escalas de Constant, Dash y UCLA, y EVA. No se registraron complicaciones mayores y solo 4 pacientes requirieron una re-operación. Conclusión: Los principales hallazgos obtenidos fueron la mejoría funcional y del dolor en los pacientes mayores de 80 años operados por una ruptura completa del manguito rotador en forma artroscópica.

Allograft-enhanced latissimus dorsi transfer is better than the conventional technique for irreparable posterosuperior rotator cuff tears. A retrospective matched cohort.

PURPOSE: Latissimus dorsi tendon (LDT) transfer (LDTT) to the greater tuberosity to treat irreparable posterosuperior rotator cuff tears (RCTs) in young active patients has been shown to have up to 36% of clinical failures, most of them happening because of either deltoid origin disruption or post-operative transfer rupture from the greater tuberosity. In an attempt to simultaneously prevent both complications, a modified technique includes the following adaptations to the original technique: reinforcement and augmentation of the LDT with a tendinous allograft, enabling the use of a single deltopectoral approach. The aim of this study is to compare mid-term outcomes of the traditional LDTT technique with this modified transfer. METHODS: Retrospective cohort study comparing two groups who underwent either the traditional (group 1; n = 19) or the modified technique (group 2; n = 27). Group homogenization was assured by statistical comparison of 24 baseline independent variables. The outcome variables were the gains to active shoulder range of motions (ROM) and UCLA scores (and all its subscores, independently), at a minimum follow-up of two years. A p value < .05 was considered to be statistically significant. RESULTS: At a mean follow-up of 25 months, both groups have shown improvements to most variables. However, group two (modified technique) achieved greater improvements to UCLA score (p = .009), active external rotation (p = .006) and internal rotation (p = .008). CONCLUSION: At mid-term follow-up, improvements to outcomes of the modified (single approach, allograft-enhanced) latissimus dorsi transfer were greater than those of the original technique.

Association between the rs820218 Variant within the SAP30BP Gene and Rotator Cuff Rupture in an Amazonian Population.

BACKGROUND: Rotator cuff disease is one of the leading causes of musculoskeletal pain and disability, and its etiology is most likely multifactorial but remains incompletely understood. Therefore, the objective of this research was to investigate the relationship of the single-nucleotide rs820218 polymorphism of the SAP30-binding protein (SAP30BP) gene with rotator cuff tears in the Amazonian population. METHODS: The case group consisted of patients who were operated on due to rotator cuff tears in a hospital in the Amazon region between 2010 and 2021, and the control group was composed of individuals who were selected after negative physical examinations for rotator cuff tears. Genomic DNA was obtained from saliva samples. For the genotyping and allelic discrimination of the selected single nucleotide polymorphism (rs820218) in the SAP30BP gene, real-time PCR was performed. RESULTS: The frequency of the A allele in the control group was four times as high as that in the case group (AA homozygotes); an association of the genetic variant rs820218 of the SAP30BP gene with rotator cuff tears was not established (p = 0.28 and 0.20), as the A allelic frequency is ordinarily low in the general population. CONCLUSIONS: The presence of the A allele indicates protection against rotator cuff tears.

Recurrence of glenohumeral instability in patients with isolated rotator cuff repair after a traumatic shoulder dislocation.

INTRODUCTION: The primary objective of this study was to assess the incidence of recurrent glenohumeral instability in patients over 40 years with isolated rotator cuff (RC) repair for traumatic shoulder dislocation. The secondary objectives were to identify risk factors for glenohumeral recurrence after RC repair and to describe the causes and incidences of re-intervention. MATERIALS AND METHODS: In this retrospective cohort study, data of consecutive patients at a single trauma center between January 2014 and July 2019 were reviewed, and 84 patients with a mean age of 57 (range: 40-75) years and follow-up duration of 3.9 (2-6) years were included. The inclusion criteria were as follows: first traumatic anterior shoulder dislocation, reparable RC tear, primary arthroscopic RC repair, no labral or bony Bankart lesion repair, and at least 2 years of follow-up. Patients less than 40 years of age were excluded. Shoulder instability recurrences and surgical reinterventions were reviewed with medical records. Statistical analysis was performed for qualitative variables using the Chi-squared test. Statistical significance was set at P ≤ 0.05. RESULTS: There was one patient with a redislocation episode (1.2%) at 2.5 years after surgery, who was surgically treated. Age, subscapular tears, bony Bankart injuries, humeral defects, and associated neurological injuries were not risk factors for recurrence in this study. Ten patients (11.9%) required reintervention. Nine patients (10.7%) re-tore their RCs. CONCLUSIONS: Recurrent glenohumeral instability in active patients over 40 years with isolated RC repair after traumatic shoulder dislocation was infrequent, despite the incidence of significant Hill-Sachs defects, anterior glenoid defects, bipolar bone defects, size of the RC injury, and tendon re-tears. The incidence of re-interventions was 11.9%, with symptomatic RC retear as the main cause.

Effects of pain neuroscience education and rehabilitation following arthroscopic rotator cuff repair. A randomized clinical trial.

OBJECTIVE: To compare the effectiveness of pain neuroscience education (PNE) versus biomedical education (BME) in a rehabilitation program following arthroscopic rotator cuff repair (ARCR) in patients with chronic shoulder pain. METHODS: Twenty-nine patients who participated in a rehabilitation program were randomly assigned to either an experimental PNE group (N = 16) or a control BME group (N = 13). Measurements included pain intensity at rest and in movement, pain catastrophizing, kinesiophobia, disability and health-related quality of life (HRQoL). Outcomes were evaluated at baseline and at 4 and 8 weeks after the intervention. RESULTS: A main effect for time was observed for: intensity of pain at rest (p < .01); pain with movement (p < .01); pain catastrophizing (p < .01); kinesiophobia (p < .01); disability (p < .01); and HRQoL (p < .01). No group interactions were significant for any variable, except for pain with movement, which favored the PNE group (p = .03). Large effect sizes (ranging from d = 0.79 to d = 2.65) were found for both interventions in all outcomes. CONCLUSION: A rehabilitation program including either PNE or BME are equally effective in improving rest pain, pain catastrophizing, kinesiophobia, disability, and HRQoL in patients after ARCR, except for pain at movement in favor of the PNE group. The inclusion of PNE in the rehabilitation program appears to lead to clinically meaningful improvements in pain at rest in short term when treating patients with ARCR.

Biceps tenotomy or tenodesis in association with rotator cuff repair: is there an influence on functional results? A retrospective cohort study.

BACKGROUND: Instability or tears of the long head of the biceps tendon (LHBT) may be present in more than 35% of rotator cuff repairs (RCR). OBJECTIVE: To compare clinical results from patients undergoing arthroscopic RCR, according to the procedure performed at the LHBT. DESIGN AND SETTING: Retrospective cohort study designed at the shoulder and elbow clinic of Instituto de Ortopedia e Traumatologia, Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo, Brazil. METHODS: Functional results among patients were compared using the American Shoulder and Elbow Surgeons (ASES) and University of California Los Angeles (UCLA) scales, according to the LHBT approach adopted: no procedure, tenotomy or tenodesis. RESULTS: We evaluated 306 shoulders (289 patients): 133 underwent no procedure at the LHBT, 77 tenotomy and 96 tenodesis. The ASES scale at 24 months showed no difference (P = 0.566) between the groups without LHBT procedure (median 90.0; interquartile range, IQR 29), tenotomy (median 90.0; IQR 32.1) or tenodesis (median 94.4; IQR 22.7); nor did the UCLA scale (median 33; IQR 7 versus median 31; IQR 8 versus median 33; IQR 5, respectively, P = 0.054). The groups differed in the preoperative functional assessment according to the ASES and UCLA scale, such that the tenodesis group started from higher values. However, there was no difference in pre and postoperative scores between the groups. CONCLUSION: Tenodesis or tenotomy of the LHBT, in the sample analyzed, did not influence the clinical results from RCR, as assessed using the ASES and UCLA scales.
