ABSTRACT

OBJETIVOS: Este estudo investiga a relação entre a amplitude de movimento e a análise histológica da sinóvia do joelho após reconstrução do ligamento cruzado anterior. MÉTODOS: Foi realizada avaliação da análise histológica da dor e da amplitude de movimento do joelho de 26 pacientes. Utilizaram-se os testes de Shapiro-Wilk, teste de Friedman, e o coeficiente de correlação de Spearman para averiguar a existência de correlações sinificativas entre as variáveis, com o software estatístico SPSS for Windows 12.0, com nível de significância de 5 por cento. RESULTADOS: Verificou-se diferença estatística na comparação entre o pré e o pós-operatório na amplitude de extensão (p= 0,042), de flexão (p= 0,001), e na amplitude de hiperextensão (p= 0,001). Foram evidenciadas correlações significativas também com a tela subsinovial e a ADM de flexão dos joelhos operados (r= 0,53; p= 0,008) e a sensação de dor (r= 0,46; p= 0,024), e entre a ADM de extensão no pós-operatório e o colágeno tipo I (r= 0,52; p= 0,016). CONCLUSÃO: Quanto maior a quantidade de colágeno tipo I, mais espessa a tela subsinovial e maior a dor, menor a ADM dos joelhos operados.


OBJECTIVE: This study investigated the relationship between range of motion and the histological analysis of the synovium of the knee joint following reconstruction of the anterior cruciate ligament. METHOD: Histological, pain and range-of-motion (ROM) evaluations were performed on the knees of 26 patients. The Shapiro-Wilk test, Friedman test and Spearman correlation coefficient were utilized for verifying the existence of significant correlations between the variables, using the SPSS for Windows 12.0 statistical software with a significance level of 5 percent. RESULTS: Comparing before and after the operation, statistical differences were found in relation to knee extension ROM (p= 0.042), flexion ROM (p= 0.001) and hyperextension (p= 0.001). There were also significant correlations between the subsynovial tissue and the flexion ROM of the operated knees (r= 0.53; p= 0.008), between the subsynovial tissue and the sensation of pain (r= 0.46; p= 0.024), and between the extension ROM after the operation and type I collagen (r= 0.52; p= 0.016). CONCLUSION: The greater the quantity of type I collagen observed, the thicker was the subsynovial tissue, the greater the reported pain, and the less was the ROM of the operated knees.
