Rehabilitation After ACL Surgery – Stages and Exercises
Rehabilitation after anterior cruciate ligament (ACL) reconstruction is key to restoring the knee and returning safely to activity. It follows the protocol and timelines set by your operating surgeon and progresses in stages.
What ACL surgery involves
The anterior cruciate ligament is one of the main stabilisers of the knee. When it tears, the knee may give way, especially in sports with pivoting and sudden changes of direction. The surgeon decides whether reconstruction is needed, taking age, activity level and knee stability into account.
After surgery the new ligament needs time to heal, and the muscles around the knee usually weaken. That is why rehabilitation starts early, but loading is increased gradually and according to the timelines set by your surgeon.
In most people full recovery takes many months. Returning to sport depends on strength, stability and confidence in the leg, not only on how much time has passed.
Why rehabilitation matters
- restoring the knee’s range of movement
- controlling swelling and pain after surgery
- rebuilding thigh muscle strength
- improving balance and knee control
- safe, gradual loading of the graft
- lowering the risk of re-injury
What is normal after surgery
- swelling and warmth around the knee
- pain and stiffness, especially in the first weeks
- limited bending or straightening of the knee
- weakness and reduced size of the thigh muscle
- a feeling of insecurity when loading the leg
- the leg tiring quickly when walking
How we can help
We work in line with your surgeon’s protocol and timelines. We start with a thorough assessment of the knee, then combine therapeutic exercise, manual therapy, therapeutic massage and methods such as electrotherapy, laser, magnet and Normatec compression to ease swelling and pain. We increase the load step by step, and if warning signs appear, we will refer you to your surgeon or another specialist. We also offer home rehabilitation with 60-minute individual sessions.
When to see a doctor
Contact your operating surgeon or seek urgent help for fever, redness or discharge from the wound, calf pain and swelling (a possible clot), sudden chest pain or breathlessness, or rapidly worsening pain. Also seek medical advice if the knee locks or suddenly gives way.
