Why is adequate fixation of the biologic ACL graft crucial during the early postoperative period?

Adequate fixation of the biologic ACL graft during the early postoperative period is crucial because it is essential for the stability and success of the reconstruction. The primary goal of ACL surgery is to restore the functional stability of the knee joint, allowing for proper biomechanics and preventing further injury. If the graft is not securely fixed, it may lead to inadequate healing, resulting in increased instability of the knee. This instability can hinder the rehabilitation process, potentially leading to a failure of the graft and persistent knee problems.

In the early stages of recovery, proper fixation allows for the graft to integrate with the surrounding tissue and for the biological healing processes to begin effectively. Without this stabilization, the graft may be subjected to excessive movement or stress, which can compromise its integration and overall success. Therefore, achieving strong and stable fixation is paramount to ensure that the graft behaves like a natural ligament and supports the knee during the rehabilitation phase and beyond.
