Anterior Cruciate Ligament (ACL) Reconstruction
motivation
Re-rupture of the anterior cruciate ligament after reconstructive surgery is reported to be between 4 and 11%. As the incidence rate of ACL rupture is increasing in young patients, this ACL reconstruction needs to be more durable and patient-specific.
A great variance of anatomical features in the knee (femoral intercondylar notch width, tibial plateau size and inclination, and dimensions of the ACL graft) play an important role in graft failure and knee instability.
Problem definition
Can you create a digital twin of the patient’s knee where different grafts can be chosen from a graft library, put in place as ACL reconstruction (ACLR) options, test the mobility of the knee, and ultimately help the surgeon predict which is the best graft?
What happens after ACLR surgery? How can you evaluate the performance of the new graft in real time and in a noninvasive manner?
