Preoperative quantitative pivot shift does not correlate with in vivo kinematics following ACL reconstruction with or without lateral extraarticular tenodesis.

研究概要

20 patients randomized to receive an ACL reconstruction alone or with a concomitant lateral extraarticular tenodesis (LET) procedure were assessed for pre-operative quantitative pivot shift (QPS) and post-operative knee kinematics. The correlation between QPS and knee kinematics was calculated to assess the potential of QPS for informing treatment decision-making, and whether an ACL reconstruction should be accompanied by a concomitant LET. The results of this study found that while QPS was associated with knee kinematics in the healthy limb at 12 months, no correlation was observed between pre-operative QPS and knee kinematics in the operated knee, in both groups. This suggests that post-ACL reconstruction knee kinematics are likely influenced by other factors.
