ACL injury treatment in Edmonton
An ACL tear usually happens without contact, often with a pop and a knee that feels unreliable. Early work at our Edmonton clinic settles the swelling, restores full extension and gets the quadriceps switching on; reconstruction is not automatic.

What is an ACL injury?
The anterior cruciate ligament sits inside the knee and stops the shin bone sliding forward and rotating on the thigh bone. Most tears happen without contact — landing, decelerating or changing direction with the knee rotating inward. People often describe a pop, then swelling that comes on within a few hours, and a knee that feels unreliable when they try to turn on it.
The first days
Rapid swelling in the first few hours is a meaningful sign: it usually means bleeding inside the joint, which points to a structure with a blood supply, and the ACL is high on that list.
Early assessment is about settling the swelling, getting the knee straight, and restoring the quadriceps’ ability to switch on — all of which matter later, whichever path you take. A clinical examination can identify most ACL tears; MRI is used to confirm and to look at the meniscus and cartilage.
Surgery is not automatic
A torn ACL does not oblige anyone to have it reconstructed. Some people regain a stable, functional knee with rehabilitation alone and go back to activity without the knee giving way; others do not, and those tend to do better reconstructed.
The factors in the decision are the sports and work you want to go back to, whether the knee gives way once quadriceps strength and control have been rebuilt, and what else was injured at the same time — a locked knee from a displaced meniscus tear, for instance, changes the conversation.
A reasonable pathway for many people is structured rehabilitation first, with the surgical decision revisited once the knee has had a fair chance to show what it can do. That is a discussion between you, your physiotherapist and an orthopaedic surgeon, not a decision made in the first week.
What rehabilitation involves
Whether or not there is surgery, the work is the same in shape: full range and a knee that straightens properly, quadriceps and hamstring strength built back to match the other leg, then landing, cutting and deceleration under control, then sport-specific load.
Progression is by criteria rather than by calendar — strength measured against the other side, hop tests, and quality of landing. Going back on a date rather than on capability is associated with re-injury.
For a reconstructed knee, returning to pivoting sport commonly takes nine to twelve months, and the last stage is the one most often cut short.
Questions people ask
Can I walk on a torn ACL?
Usually, once the initial swelling settles. Walking in a straight line does not demand much from the ACL. The difficulty shows up in turning, pivoting and sudden stops, which is why the knee can feel fine right up until it gives way.
Do I need an MRI straight away?
Not necessarily on day one. It is used to confirm the diagnosis and to check the meniscus and cartilage, and it usually feeds into a surgical opinion rather than changing the first two weeks of care.
If I have surgery, when can I play again?
For pivoting sport, commonly nine to twelve months, and the decision should rest on strength and control testing rather than the date. Returning early with an under-strength quadriceps is one of the clearer risk factors for a second injury.
Will my knee get arthritis?
The risk of later knee osteoarthritis is raised after an ACL injury, and that appears to hold whether or not the ligament is reconstructed — much of it relates to the injury itself and to any meniscus damage. Building and keeping leg strength is the part you have influence over.
Do I need surgery for a torn ACL?
Not everyone does. People who do not pivot or cut in their sport often do well with rehabilitation alone, and a structured trial of rehabilitation before deciding is now common practice. The physiotherapist will tell you which group you are likely in and coordinate with your surgeon.
How long until I can play sport again?
Nine months or more after reconstruction is the usual guidance, and the return is decided by strength and hop testing, not the date. Returning earlier is where re-injury rates climb. That is true whether or not you had surgery.
Can I start physiotherapy before my surgery date?
Yes, and it is worth doing. Prehabilitation to restore full straightening, reduce swelling and rebuild quad strength before the operation is linked with a smoother recovery afterwards. Book as soon as you have a diagnosis rather than waiting for the surgical date.
