The ACL keeps the shin bone from sliding forward and twisting under the thigh bone. It usually tears during a sudden stop, a cut or an awkward landing, often with no contact at all. With or without surgery, rehab decides how well the knee works afterward: getting it fully straight, rebuilding the thigh muscles, and testing you before you cut and jump again.
Then
“After his ACL surgery, this has been such a long and emotional road for our family…”
Now
“…helping him get back to doing what he loves most: playing football.”
What does an ACL tear feel like?
- A pop at the moment of injury
- Swelling within the first few hours
- The knee giving way when you turn or pivot
- Trouble fully straightening or bending the knee
- Not trusting the knee on stairs or uneven ground
What usually causes it?
- Planting the foot and cutting or pivoting
- Landing from a jump with the knee caving inward
- Stopping suddenly while running
- A direct hit to the knee, as in football or soccer
How can physical therapy help?
- Prehab before surgery to calm swelling and restore motion
- Getting the knee fully straight early, then rebuilding the bend
- Progressive thigh, hamstring and hip strengthening, including blood flow restriction training while heavy lifting is not yet safe
- Staged progressions for running, jumping and cutting
- Strength and hop testing against the other leg before you return to sport
When should I get it checked?
As soon as you can after the injury, ideally before you see the surgeon. Early care keeps swelling down and the knee moving, and surgeons generally prefer to operate on a knee that is calm and straightens fully.
See a doctor right away if you notice
- The knee is locked and will not straighten
- Severe pain, or the knee looks out of place
- Numbness, coldness or a color change in the foot
- Calf pain, redness and swelling after surgery (possible blood clot)
Questions about an ACL tear
Do I always need surgery for a torn ACL?
Not always. People who do not play cutting or pivoting sports sometimes do well with rehab alone. Most athletes who want to get back to soccer, football or basketball choose reconstruction. That decision is between you and your surgeon, and we can prepare you for either path.
How long until I can play again?
As a general guide from the American Academy of Orthopaedic Surgeons (not a promise for any one person), most people are cleared for full sports 6 to 12 months after reconstruction. Time alone is not enough, though: we use strength and hop tests so the decision rests on how your knee performs.
Should I do therapy before surgery?
Yes, if you can. Going into surgery with less swelling, a knee that straightens fully and stronger thigh muscles tends to make the first weeks after surgery easier.
Why does getting the knee straight matter so much?
A knee that does not fully straighten changes how you walk and overloads the joint. It is much easier to regain early than months later, so it is a priority from the first visit.
Can I tear it again?
Yes. The risk of a second ACL tear, in either knee, is real, especially for younger athletes who return early. Finishing rehab and passing return-to-sport testing lowers that risk.
Do you follow my surgeon's protocol?
Yes. We follow your surgeon's protocol and timelines and send progress updates. Bring any paperwork from your surgeon to your first visit.
