RESUMO
OBJECTIVE: To evaluate the functional outcome of the remplissage technique, the healing of the capsulotenodesis of the infraspinatus tendon in Hill-Sachs lesion, and the degree of fatty infiltration of the infraspinatus muscle and its postoperative strength. METHODS: Twenty-five patients with recurrent anterior dislocation of the shoulder and Hill-Sachs lesion with a Hardy index > 20% who underwent the remplissage arthroscopic technique were evaluated with a minimum follow-up of 1 year. Patients underwent a clinical evaluation (Carter-Rowe and Walch-Duplay functional scores, measurement of range of motion and strength) and a magnetic resonance imaging (MRI) exam on the operated shoulder. RESULTS: Eighty-eight percent and 92% of the patients had good or excellent scores in the functional assessments of the Carter-Rowe and Walch-Duplay scores, respectively. A mean difference of - 1 kg in the strength of the operated limb was observed when compared with the contralateral limb ( p < 0.001), as well as a mean difference of 10° in external rotation 1 and 2 ( p < 0.001), also compared with the contralateral side. All of the patients who underwent an MRI exam presented high-grade filling of the Hill-Sachs lesion by capsulotenodesis, as well as absence of or minimal fatty infiltration in the infraspinatus muscle. CONCLUSION: The remplissage technique had good/excellent functional score results, despite the discrete, albeit statistically significant, loss of strength and of external rotation amplitude. Successful capsulotenodesis healing and filling of the Hill-Sachs defect were demonstrated.

Resumo Objetivos Avaliar o resultado funcional da técnica de remplissage, a cicatrização da capsulotenodese do tendão infraespinal no defeito de Hill-Sachs, o grau de infiltração gordurosa do músculo infraespinal e sua força de rotação lateral no pós-operatório. Método Foram avaliados 25 pacientes comluxação anterior recidivante do ombro e lesão de Hill-Sachs comíndice de Hardy maior do que 20%, submetidos à técnica artroscópica de remplissage com seguimento mínimo de um ano. Os pacientes foram submetidos a avaliação clínica (escores funcionais deCarter-RoweeWalch-Duplay,medição de amplitude de movimento e força) e exame de ressonância magnética no ombro operado. Resultados Dos pacientes, 88% e 92% apresentaram resultados bons ou excelentes nas avaliações funcionais pelos escores de Carter-Rowe e Walch-Duplay, respectivamente. Identificou-se diferença média de 1 kg a menos de força do membro operado em relação ao contralateral (p < 0,001) e diferença média de 10° em rotação lateral 1 e 2 (p < 0,001), novamente com o uso como referência do lado contralateral. Todos os pacientes submetidos a ressonância magnética apresentaram preenchimento de alto grau da lesão de Hill-Sachs pela capsulotenodese, assim como ausência ou mínima infiltração gordurosa no músculo infraespinal. Conclusão A técnica de remplissage apresentou resultados bons/excelentes nos escores funcionais, apesar da perda discreta de força e amplitude de rotação lateral com significância estatística. Foram observados resultados excelentes quanto à cicatrização da capsulotenodese e ao preenchimento do defeito de Hill-Sachs.
