No pain. Why need surgery ?

Yes, it is normal as with time the initial injury settles and the swelling goes away and hence pain disappears. But your ACL is still damaged, and your knee is still moving abnormally which will lead to damage to meniscus, cartilage and other ligaments, which can lead to early osteoarthritis.

This is call as fake knee. The knee feels okay and normal, but inside damage continues. Such patients typically come after 2-3 years of their injury with pain. By that time then the cartilage lining of the knee is damaged and success of surgery is reduced.

ACL is very important for sports activities as it helps athletes to turn and change directions. These cutting movements are very important in sports such as hockey, football, kabaddi etc.

When the ligament breaks patients can still jog and run with time in a straight line but twisting or changing direction becomes lost. This loss leads to decreased performance and in some patients they are unable to return to their pre-injury levels or to the sport at all. ACL surgery is able to restore you back to your pre-injury levels and return you to sports.
