Abstract

The pivot-shift clinical test is commonly used for the qualitative evaluation of knee dynamic stability [Hoshino, 2007]. With the aim of controlling the static antero-posterior laxity as also tibial subluxation, many surgeons have started performing anatomical double-bundle (DB) ACL reconstructions [Zelle, 2007], since it seems to have superior outcomes with respect to the Lachman’s test and pivot-shift phenomenon, but a quantitative assessment about the global laxity is still not provided. The aim of this study was thus to quantify intra-operatively the improvements in knee dynamic stability, compared to standard evaluations, due to an anatomical DB ACL reconstruction, paying attention to pivot-shift test.
