Abstract
in English, Portuguese

Objective: To evaluate the influence of partial- and full-thickness upper third subscapularis tendon tears on the functional scores of patients undergoing arthroscopic rotator cuff repair.

Methods: Patients who underwent arthroscopic rotator cuff repair were divided into three groups according to the subscapularis tendon condition: intact, partial-thickness tear, or full-thickness upper third tear. Functional scores were compared among groups. Second, the influence of biceps and infraspinatus tears on the scores was tested using multivariate regression analysis.

Results: We evaluated 307 shoulders in 297 patients. Full-thickness upper third subscapularis tears presented significantly worse scores than intact tendons. Partial-thickness tears had scores that did not differ significantly from those of the other groups. Patients with full-thickness upper third tears presented a greater rate of injured and unstable biceps tendons. The multivariate analysis showed that biceps and infraspinatus tendon tears did not influence the scores or the intergroup comparison.

Conclusion: Full-thickness upper third subscapularis tendon tears presented worse functional scores than intact subscapularis tendons among patients undergoing posterosuperior rotator cuff repair. Patients with full-thickness subscapularis tears were more likely to suffer biceps tears, but this fact did not influence functional scores. Level of Evidence I; Clinical randomized trial.

Objetivo: Avaliar a influência das lesões do terço superior do tendão subescapular nos escores funcionais de pacientes submetidos ao reparo artroscópico do manguito.

Métodos: Divisão em três grupos, conforme condição do tendão subescapular: intacto; ruptura de espessura parcial ou ruptura do terço superior de espessura total. Comparamos escores funcionais. Em seguida, a influência das lesões do bíceps e do infraespinhal nos escores foi testada através de análise de regressão multivariada.

Resultados: Avaliamos 307 ombros em 297 pacientes. Rupturas subescapulares no terço superior de espessura total apresentaram escores significativamente piores aos pacientes com tendão intacto. Rupturas de espessura parcial apresentaram escore sem diferença significativa em relação aos demais. Pacientes com rupturas do terço superior de espessura total apresentaram maior taxa de lesão e instabilidade tendínea do bíceps. Análise multivariada mostrou que as rupturas tendíneas do bíceps e infraespinal não influenciaram os escores.

Conclusão: Pacientes com lesão do terço superior de espessura total do tendão do subescapular apresentaram escores funcionais piores do que pacientes com tendão intacto submetidos ao reparo artroscópico posterossuperior do manguito. Pacientes com rupturas do subescapular com espessura total foram mais propensos a apresentar rupturas do bíceps, sem influenciar escores funcionais. Nível de Evidência I, Estudo clínico randomizado.
