Resumo
Objetivo
Investigar o valor dos exames clínicos para diagnóstico de rupturas do ligamento cruzado anterior (LCA) com os testes da gaveta anterior, Lachman, pivot-shift, sinal de alavanca e sinal de flambagem ativa forçada (FAB, do inglês forced active buckling).
Métodos
Este estudo transversal foi conduzido com 165 pacientes com lesão no joelho e indicação para artroscopia, entre janeiro e dezembro de 2022. Os resultados dos exames clínicos foram comparados ao padrão-ouro do procedimento para determinar o valor dos testes diagnósticos.
Resultados
Os valores de sensibilidade e especificidade foram, respectivamente: teste da gaveta anterior: 77,5% e 86,1%; Lachman: 87,6% e 88,9%; pivot-shift: 65,9% e 94,4%; sinal de alavanca: 93,8% e 94,4%; e sinal de FAB: 81,4% e 97,2%.
Conclusão
Há diversos exames clínicos para rupturas do LCA. O sinal da alavanca é um teste clínico útil para exame e diagnóstico dessa condição.
Abstract
Objective
To investigate the value of clinical diagnostic tests for diagnosing anterior cruciate ligament (ACL) tears with the anterior drawer, Lachman, Pivot-shift, Lever sign, and Forced Active Buckling (FAB)sign tests.
Methods
A cross-sectional study was conducted on 165 knee injury patients who were indicated for knee arthroscopy from January to December 2022. The clinical examination results were compared with the procedure's gold standard to determine the value of clinical diagnostic tests.
Results
The sensitivity and specificity values, respectively, were anterior drawer test: 77.5% and 86.1%; Lachman: 87.6% and 88.9%, Pivot-shift: 65.9% and 94.4%; Lever sign: 93.8% and 94.4%; and FAB sign: 81.4% and 97.2%.
Conclusion
There are various clinical diagnostic tests for ACL tears. The Lever sign is a useful clinical test for physicians to examine and diagnose ACL tears.
