ACL grafts compliance during time: Influence of early solicitations on the final stiffness of the graft after surgery

Following practices with the Lachman Test (subjective assessment), we observe how rehabilitation and daily stress applied on the ACL after ACL surgery impacts the stiffness (or the compliance of the ligament graft over time and the repercussion it has on the knee (stability or clinical instability of the patient’s knee) but it was without any objective measurements and precise follow-up. The more the constraints applied on the graft are inadapted and harmful, the more the risk of functional instabilities is high when returning to pivot sport activities. The study design was to analyze with more accuracy the evolution of stiffness ‘grafts during ligamentization (healing) time…
