ACL injury · Knee rehabilitation · Booragoon
Your knee is feeling better after an ACL injury. But is it ready for everything you want to do?
Maybe the swelling has settled and walking feels normal again. You can get through the day without thinking much about your knee, and you're keen to get back to training or sport.
That's encouraging progress. But feeling better and being ready for the demands of running, jumping, turning and competition aren't necessarily the same thing. ACL recovery involves rebuilding strength, movement capacity and confidence—whether you've had surgery or are following a non-surgical rehabilitation plan.
At Adaptive Physiotherapy & Massage in Booragoon, we start with where your knee is now, what you want to return to and the steps needed to get there. Our knee physiotherapy and sports rehabilitation services support that progression.
Why sticking with ACL rehabilitation matters
Recovering from an anterior cruciate ligament (ACL) injury takes time. It's tempting to reduce your rehab once the pain settles, but comfort during everyday activities doesn't necessarily mean strength, knee control or sport readiness have fully returned.
Some people recover with a non-surgical approach; others undergo ACL reconstruction. Treatment choices and rehabilitation restrictions depend on the injury, any associated meniscus or cartilage damage, the surgical procedure and the person's goals.
Important: The timeframes below are a general guide, especially for ACL reconstruction. They are not a clearance schedule. Your treating team should adapt them to your injury and any surgeon-specific restrictions. Progress is assessed through symptoms, movement, strength and functional testing—not the calendar alone.
Your ACL recovery pathway
Early recovery: settle symptoms and restore movement
Often the first couple of weeks after injury or surgery
Immediately after injury or surgery, the focus is on protecting the knee, managing pain and swelling, restoring comfortable movement and beginning appropriate muscle activation.
Goals
- Manage pain and swelling.
- Work towards full knee extension and gradually recover flexion within the plan.
- Activate the quadriceps and surrounding muscles.
- Walk safely, using crutches or a brace if prescribed.
What your program may include
- Compression, elevation and cold therapy for temporary symptom relief when appropriate.
- Heel slides, knee extension exercises and gentle quadriceps contractions.
- Advice on walking, weight-bearing and appropriate activity.
A brace or crutches is not required for everybody. Follow surgical and medical advice, particularly if other structures were repaired.
Early rehabilitation: movement and foundation strength
Often during the first several weeks
As swelling and symptoms improve, the aim is to build on your initial movement and gradually develop weight-bearing capacity and strength. This work can seem basic, but it provides an important foundation.
Goals
- Improve knee range of motion and walking confidence.
- Rebuild quadriceps and lower-limb strength.
- Develop tolerance for manageable daily activity.
What your program may include
- Heel slides, controlled knee extension and straight leg raises when suitable.
- Mini squats, bridges and progressive weight-bearing exercises.
- Walking and stationary cycling when appropriate.
- Manual therapy as an optional adjunct for stiffness or discomfort.
Your physiotherapist will reassess swelling, movement and muscle function before progressing the load.
Strength and movement control
Often developed across the following months
When your knee is moving more comfortably, rehabilitation builds towards the strength and control needed for more demanding activity. Feeling good during a walk is different from tolerating single-leg loading or repeated gym work.
Goals
- Build quadriceps, hamstring, glute and calf strength.
- Improve balance, single-leg capacity and movement control.
- Increase endurance and confidence under load.
What your program may include
- Leg presses, step-ups, squat and lunge progressions.
- Progressive hamstring and quadriceps resistance training.
- Single-leg balance and controlled functional tasks.
- Cycling, swimming or other aerobic exercise when suitable.
Progressive strength testing helps identify deficits that can remain even when daily activities feel normal.
Higher-level strength, running and athletic movement
Introduced when physical criteria and individual restrictions allow
For people returning to running or sport, rehabilitation becomes more specific. The focus shifts from basic strength towards the ability to produce and absorb force, move at speed and respond to sporting demands.
Goals
- Build advanced strength and power.
- Develop running and landing capacity where relevant.
- Prepare for acceleration, deceleration and direction changes.
What your program may include
- Running progressions once suitable strength, swelling and functional criteria are met.
- Controlled jumping and landing drills.
- Agility, lateral movement and change-of-direction progressions.
- Sport-specific skills developed in collaboration with coaches when appropriate.
Not everyone needs cutting or plyometric drills. A return to gardening, work or recreational gym training involves different demands from a return to football or netball.
Return to sport or higher-demand activity
Timing varies; return to pivoting sport is not determined by months alone
Returning to training is not always the same as being ready to compete. Your knee needs to manage the demands of your particular sport, and your confidence matters too.
What your physiotherapist may assess
- Pain, swelling, range of motion and knee stability.
- Quadriceps and hamstring strength using appropriate tests.
- Single-leg jumping, landing, running and change-of-direction capacity as relevant.
- Sport-specific training tolerance and psychological readiness.
- Any clearance or restrictions from your surgeon or medical team.
For young athletes and those returning to pivoting sports, these decisions deserve particular care. See our Youth Athlete Physiotherapy and Sports Physiotherapy services.
Maintaining your progress
Reaching a milestone doesn't mean all strengthening needs to stop. Continuing an appropriate program can help maintain physical capacity and prepare you for ongoing training, work or recreation.
At Adaptive, rehabilitation is adjusted as you improve. That might mean progressing gym exercises, building running volume, improving landing control or developing a plan you can maintain independently. Where it adds value, we can collaborate across physiotherapy and strength coaching to support the transition to higher-level activity.
When to contact your treating team
Seek prompt advice if you develop increasing knee swelling, worsening pain, new giving-way episodes or a substantial loss of movement. After surgery, urgent medical assessment may be required for fever, a red or draining wound, significant calf swelling or pain, chest pain or breathlessness. Chest pain or breathlessness may be an emergency—call 000.
