Background: Persistent instability of the knee is reported in up to 30% of patients after anterior cruciate ligament (ACL) reconstruction. Based on anatomic findings showing that ACL is a flat ribbon-like structure that twists during knee flexion, a new surgical ACL reconstruction technique using a ribbon-like graft has been developed. However the effect of this surgical technique on knee kinematics has not yet been evaluated.

- The study aimed to evaluate the stabilizing effects of anterolateral ligament reconstruction (ALLR) and modified Lemaire lateral extra-articular tenodesis (LET) when combined with anterior cruciate ligament reconstruction (ACLR).
- Researchers tested six human cadaver knees using a robotic system to measure internal rotation and anterior translation in various conditions, including after ligament injuries and surgeries.
- Results indicated that both ALLR and modified Lemaire LET effectively restored knee stability to near normal levels after ACLR, with no significant difference in efficacy between the two procedures.
Background: Blood supply of the proximal metaphysis of the femur comes mainly from the lateral circumflex femoral artery (LCFA). Essentially, the anterior approach has gained popularity in hip surgery but routinely requires the ligation of the ascending branch of the LCFA. Until now, there is no study analysing the effect of previous hip surgery on the vascularization of the proximal femur.
