    Does a subscapularis tear combined with a posterosuperior rotator cuff tear affect postoperative functional outcomes?
    (2020) MALAVOLTA, Eduardo Angeli; CHANG, Veronica Yulin Prieto; MONTECHI, Joao Marcos Nunes; ASSUNCAO, Jorge Henrique; GRACITELLI, Mauro Emilio Conforto; ANDRADE-SILVA, Fernando Brandao; FERREIRA NETO, Arnaldo Amado
    Background: The subscapularis is biomechanically important for the shoulder. However, few studies have clinically assessed its importance using a comparative design. Our objective was to compare the functional outcomes in patients who underwent isolated repair of posterosuperior rotator cuff tears and those with repair of combined tears involving the subscapularis. Methods: We performed a retrospective cohort study evaluating patients who underwent arthroscopic full-thickness rotator cuff repair between January 2013 and May 2017. The patients were divided into 2 groups: isolated repair of posterosuperior tears and repair of combined tears involving the subscapularis. The primary outcome was to evaluate the American Shoulder and Elbow Surgeons (ASES) and University of California, Los Angeles (UCLA) scales at 24 months' follow-up. Result: A total of 326 patients were evaluated: 194 with isolated posterosuperior repairs and 132 with combined subscapularis repairs. Both groups showed significant improvement with the procedure (P <.001). The ASES score at 24 months showed no significant difference (P = .426) between the group without subscapularis repair (median, 90.0; interquartile range [IQR], 24.8) and the group with subscapularis repair (median, 86.3; IQR, 33.2). Similarly, the UCLA score showed no difference between the groups (median, 33.0 [IQR, 6.0] and 32.5 [IQR, 8.8], respectively; P =.190). The preoperative functional evaluation also showed no significant differences between the groups. Conclusion: The functional results did not differ between patients who underwent isolated repair of posterosuperior tears and those with repair of combined tears involving the subscapularis, according to the ASES and UCLA scales at 24 months.

    Outcome assessment in the treatment of rotator cuff tear: what is utilized in Brazil?
    (2017) ASSUNÇÃO, Jorge Henrique; MALAVOLTA, Eduardo Angeli; DOMINGUES, Vitor Rodrigues; GRACITELLI, Mauro Emilio Conforto; FERREIRA NETO, Arnaldo Amado
    ABSTRACT This review evaluated the outcomes used in clinical studies involving rotator cuff tear published in the last decade in the two leading Brazilian orthopedic journals. A literature review was performed using the journals Revista Brasileira de Ortopedia and Acta Ortopédica Brasileira. It included all original clinical articles describing at least one outcome measured before or after any clinical or surgical intervention related to rotator cuff tear, published between 2006 and 2015. The authors evaluated range of motion, muscle strength, patient satisfaction, and tendon integrity and functional outcomes scores. There were 25 clinical studies published about rotator cuff in the two principal Brazilian orthopedic journals in the last decade, 20 case series (80%), one case-control (4%), and four cohorts (16%). Objective measures such as muscle strength, patient satisfaction, and evaluation of tendon integrity were little used. Range of motion measurements were performed in 52% of the articles. Evaluations of muscle strength and patient satisfaction were reported by 28% and 16% of the studies, respectively. Only 28% of the articles evaluated tendon integrity after surgery. Of these, 16% did so by magnetic resonance imaging and 12% by , ultrasonography. The most used scale was the UCLA, present in 92% of the articles, while the Constant-Murley appeared in 20%. Scales deemed reliable, with high internal consistency and good responsiveness, were rarely used.

    Correlation between the UCLA and Constant-Murley scores in rotator cuff repairs and proximal humeral fractures osteosynthesis
    (2018) MALAVOLTA, Eduardo Angeli; ASSUNÇÃO, Jorge Henrique; GRACITELLI, Mauro Emilio Conforto; SIMÕES, Pedro Antonio Araújo; SHIDO, Danilo Kenji; FERREIRA NETO, Arnaldo Amado
    ABSTRACT Objective: To evaluate the correlation between the UCLA and Constant-Murley scores in the surgical treatment of rotator cuff tears and proximal humeral fractures (PHF). Methods: Retrospective study evaluating patients submitted to arthroscopic rotator cuff repair and surgical treatment of PHF with 2-year follow-up. Patients were evaluated by the UCLA and Constant-Murley scores in the preoperative period for the rotator cuff repairs, and 3, 6, 12 and 24 months after surgery for both diagnoses. Pearson's correlation coefficient (r) was calculated to measure the degree of correlation between the two clinical scales. Results: We evaluated 109 patients: 54 with rotator cuff tear and 55 with PHF. Twenty-four months after surgical treatment, the scores according to the UCLA and Constant-Murley scores were 32.6 ± 4.0 and 85.0 ± 12.0 for the rotator cuff tears and 30.3 ± 5.3 and 73.8 ± 13.9 for the PHF, demonstrating significant improvements in both, in relation to the initial evaluation (p < 0.001). The scales demonstrated high correlation (r = 0.88, p < 0.001). The scores obtained in the two scales showed high or very high correlation in all the postoperative clinical evaluations (r = 0.79-0.91, p < 0.001). The correlation was high in the preoperative evaluation (r = 0.73, p < 0.001). Conclusion: The UCLA and Constant-Murley scores presented high or very high correlation in the evaluation of surgical treatment of rotator cuff tears and PHF. The correlation in the preoperative evaluation was high.

    Anterior Glenohumeral Instability: Systematic Review of Outcomes Assessment Used in Brazil
    (2019) ASSUNÇÃO, Jorge Henrique; MALAVOLTA, Eduardo Angeli; SOUZA, Fernando José de; GRACITELLI, Mauro Emilio Conforto; FERREIRA NETO, Arnaldo Amado
    Abstract A review involving the six major international orthopedic journals has been published recently. It described the tools used for the evaluation of outcomes in the surgical treatment of recurrent anterior dislocation of the shoulder. There are no studies that exhibit the main outcome tools for this disease in Brazil. The authors evaluated the outcomes of clinical studies involving anterior glenohumeral instability that were published in the last decade in the two leading Brazilian orthopedic journals, Revista Brasileira de Ortopedia and Acta Ortopédica Brasileira. A review of the literature was performed, including all clinical papers published between 2007 and 2016 describing at least one outcome measure before and after surgical intervention. The outcomes were range of motion, muscle strength, physical examination testing, patient satisfaction, return to sports, imaging, complications, and functional outcomes scores. Twelve studies evaluating the clinical outcomes of surgical treatment for anterior shoulder instability were published. Ten studies (83%) were case series (level of evidence IV), 1 (8%) was a case-control study (III), and 1 was a retrospective cohort (III). On average, the number of outcomes assessed was 3.7 ± 1.7. The Rowe score was used in 9 studies (75%), and 7 (58%) papers used the University of California Los Angeles (UCLA) scale. Ten studies (83%) reported complications related to surgical treatment. The complication most frequently reported was recurrent instability, found in 9 studies (75%). The national studies have preferentially used scales considered to be of low reliability, responsiveness, and internal consistency.

    (2022) MALAVOLTA, Eduardo Angeli; MARTINEZ, Luca; GRACITELLI, Mauro Emilio Conforto; ASSUNÇÃO, Jorge Henrique; ANDRADE-SILVA, Fernando Brandão; FERREIRA NETO, Arnaldo Amado
    Abstract Objective To evaluate the functional outcome of patients who underwent partial arthroscopic repair of massive rotator cuff tears. Methods Retrospective case series evaluating patients with massive rotator cuff tears who underwent partial arthroscopic repair. The primary outcome was the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) at 24 months. The secondary outcomes were the Modified-University of California at Los Angeles Shoulder Rating Scale (UCLA), and the following subdomains: satisfaction, active forward flexion and strength of forward flexion subdomains. Results We evaluated 33 patients. The ASES scale evolved from 39.7 ± 19.6 to 77.6 ± 17.4 (p< 0.001). The UCLA scale evolved from 13.3 ± 5.5 to 27.9 ± 5.6 (p< 0.001). The satisfaction rate was 97%. The number of patients with active forward flexion > 150° increased from 12 (36.4%) to 25 (75.8%) (p= 0.002). The number of patients with normal or good strength of forward flexion increased from 9 (27.3%) to 22 (66.7%) (p = 0.015). Conclusion Partial repair of irreparable rotator cuff tears leads to significant improvement according to the ASES and UCLA scales.

    (2017) FERREIRA NETO, Arnaldo Amado; MALAVOLTA, Eduardo Angeli; ASSUNÇÃO, Jorge Henrique; TRINDADE, Evelinda Marramon; GRACITELLI, Mauro Emilio Conforto
    ABSTRACT OBJECTIVE: To evaluate the clinical and radiological results and the impact on quality of life of the reverse shoulder arthroplasty. METHODS: Retrospective case series evaluating 13 patients undergoing reverse shoulder arthroplasty with at least two years of clinical follow-up. Clinical evaluation was performed before and after surgery with the ASES and VAS scales and hand-mouth, hand-neck, and hand-head functional tests. Quality of life was measured with the SF-12 questionnaire. The rate of complications and radiographic postoperative findings were recorded. RESULTS: The patients improved from 23.1 ± 15 to 82.7 ± 15 according to ASES scale (p < 0.001). The physical component of the SF-12 increased from 31.7 ± 6.9 to 47.1 ± 8.6 (p < 0.001), while the emotional increased from 48 ± 12.3 to 55.5 ± 7.5 (p = 0.061). The pain reduced from 7.9 to 1 according to the VAS (p = 0.002). The performance on the hand-mouth, hand-neck, and hand-head functional tests showed significant improvement (p = 0.039, p < 0.001 and p < 0.001, respectively). Complications occurred in 15% of patients and notching, in 31%. CONCLUSION: Reverse shoulder arthroplasty led to a significant clinical improvement according to the ASES and VAS scales. The quality of life has improved according to the physical aspect of the SF-12, and showed a trend of improvement in the emotional aspect. The complication rate was 15%, and notching occurred in 31%.

    Tomographic evaluation of Hill-Sachs lesions: is there a correlation between different methods of measurement?
    (2017) ASSUNCAO, Jorge Henrique; GRACITELLI, Mauro Emilio Conforto; BORGO, Gustavo Dias; MALAVOLTA, Eduardo Angeli; BORDALO-RODRIGUES, Marcelo; FERREIRA NETO, Arnaldo Amado
    Background Several methods are currently available to evaluate and quantify the glenoid or humeral bone loss; however, none is universally accepted, particularly in the case of Hill-Sachs (HS) lesions. Purpose To establish whether there is correlation among different methods of measuring HS lesions, and to investigate the correlation between glenoid bone loss and the various HS lesion measurements and to assess the inter-observer reliability of such measurements. Material and Methods We assessed computed tomography (CT) or arthro-CT scans taken from individuals with recurrent anterior glenohumeral dislocation. The scans were independently assessed by two examiners. The parameters assessed were as follows: HS lesion width and depth on the axial and coronal planes, articular arc loss on the axial plane, and percentage of glenoid bone loss on the sagittal plane. Results Scans from 50 shoulders were assessed. The percentage of articular arc loss and HS lesion width on the axial plane were the only measurements that exhibited strong correlation (r=0.83; P<0.001). The values of the correlation coefficient corresponding to HS lesion depth on the coronal plane were the lowest. Most of the measurements exhibited moderate correlation. The inter-examiner reliability was good relative to all measurements except for HS lesion width and depth on the coronal plane, for which it was moderate. Conclusion The measurements of articular arc loss and HS lesion width on the axial plane exhibited strong correlation. The inter-examiner reliability relative to articular arc loss, HS lesion width and depth on the axial plane, and glenoid bone loss was good.

    MESENCHYMAL CELLS IN ROTATOR CUFF REPAIR -TECHNIQUE DESCRIPTION AND CASE REPORTS
    (2023) MALAVOLTA, Eduardo Angeli; MICELI, Vinicius Lamboglia; ASSUNCAO, Jorge Henrique; ANDRADE-SILVA, Fernando Brandao; GRACITELLI, Mauro Emilio Conforto; TATSUI, Nelson Hidekazu; ESPIRANDELLI, Luiz Cesar; NETO, Arnaldo Amado Ferreira
    Objective: To describe a protocol of obtention of mesenchymal stem cells and to report their use as a biological adjuvant in three patients undergoing arthroscopic rotator cuff repair. Methods: Case series of patients who underwent arthroscopic repair of isolated full-thickness supraspinatus tear using mesenchymal stem cells obtained from the bone marrow as a biological adjuvant. All patients were operated on at the same institution, by a surgeon with 13 years of experience. The cells were applied at the end of the procedure, at the tendon-bone interface, at an approximate concentration of 2,000,000 mesenchymal cells/mm3 and a total volume of 5 ml. Results: All patients improved with the procedure, with one excellent and two good results. All cases overcame the minimally important clinical difference. All cases reached tendon healing, without partial or complete re-tears. We observed no complications. Conclusion: Arthroscopic rotator cuff repair with added mesenchymal cells obtained from bone marrow and submitted to a cell expansion process led to good functional results and healing in all cases in the sample, with no complications. Level of Evidence IV, Case Series.
