The rehab timeline after ACL surgery goes like this. Most athletes will go back to their sport around 9-12 months after the ACL surgery. Around 3 months you should be able to start jogging again. Around 4-6 months begin jumping and around 8-9 months begin sport-specific training.

In the past, athletes were allowed to return to sport as early as 6 months. However, it was quickly found that 6 months was too early. There were many athletes who re-tore their ACL and had to start all over again. Ain’t Nobody Got Time For That!

Why does ACL rehab take so long?

During the ACL surgery a tunnel is drilled through your tibia and your femur, the ACL is then affixed into the bone. There are different methods of fixating the ACL within the bone tunnels.

However, one thing that all of these methods have in common is needing time for the graft to attach, or to “take.” Usually we want to be very protective of the graft during the initial 3 months. Hence there are strict activity restrictions. We don’t want to take a chance on tearing the graft.

In that downtime, most athletes start to lose their game strength and conditioning.

Please take 4 minutes to watch this animated video that gives you an overview of the ACL surgery using a hamstring tendon. I hope that after seeing the complexity of the surgery, the bone drilling and graft placement you can appreciate the time that our bodies need in order to heal from this procedure.

Is there anything I can do to speed up the rehab?

In short…”No”. I think the best approach is learning about why the rehab and healing takes so long as well accepting this as a challenge to work on your patience and understanding of the process. Have you ever done gardening before? Stick with me here.

If you have a plant growing and you tear it out (like you tore your ACL) and now you are trying to plant a new thing there (the graft) you know that those roots need time to grow into the ground. If you tug on the plant too early before the roots had time to grow into the ground the plant will come right out. You don’t want that to be your ACL.

After surgery one of the most predominant things you will notice is the weakness in your thigh muscle, better known as the quadriceps, or just the quad. This large muscle is responsible for straightening your knee and keeping the knee from buckling on you. If you start pushing the quad muscle beyond what it’s capable of, the knee will buckle and it will more then likely tear the ACL out of its tunnel. If that happens, you will require surgery again and will have to start the whole process all over.

Knowledge is power and the more you can set realistic expectations the better experience you will have over the entire process.
