Ligamentization

Ligamentization is the biological process by which a graft, such as a transplanted tendon used to replace a torn ligament, gradually transforms to resemble a natural ligament. After surgery, the graft initially undergoes healing and integration with surrounding tissues. Over time, it undergoes cellular changes, gradually developing the structure, fiber organization, and strength similar to a natural ligament. This process can take several months to years and is crucial for restoring normal joint stability and function. Ultimately, ligamentization helps ensure the graft becomes a durable, biologically integrated replacement that effectively manages mechanical stresses.
