✅ ACL Scarring:
- The scar tissue from the ACL most frequently attaches to the lateral side of the proximal PCL and the intercondylar notch.
- It is less common for the scar to attach back to the ACL's original attachment point.
- Among these patterns, scarring that reconnects the ACL to its original attachment point is rare but results in the most significant improvement, leading to reduced laxity (looseness) during clinical examinations.
- Even if the ACL forms a continuous structure through scarring, the healed ligament is usually functionally weaker than before the injury.
