In many cases, you can exercise with an ACL injury, but the exercises should match the severity of the injury, knee stability, and stage of recovery. Low-impact strengthening and mobility exercises may support recovery, while running, jumping, pivoting, and high-impact activities may increase stress on the injured knee. Dr. Abhinandan Punit, an Orthopaedic Surgeon in Bangalore with 15+ years of experience, provides assessment and treatment guidance for ACL and knee ligament injuries.
What Is an ACL Injury?
The Anterior Cruciate Ligament (ACL) is one of the major ligaments that helps stabilise the knee. An ACL injury can occur during sports, sudden twisting, jumping, landing, or direct impact to the knee.
ACL injuries are commonly classified as:
- Grade 1: Mild ligament stretching
- Grade 2: Partial ACL tear
- Grade 3: Complete ACL tear
The severity of the injury can affect which exercises are appropriate. Patients with persistent symptoms can explore knee ligament injury treatment for further evaluation and treatment options.
Can You Exercise With an ACL Injury?
Yes, many people can continue selected exercises after an ACL injury. Controlled exercise can help maintain muscle strength, mobility, and overall fitness during recovery.
However, not every exercise is suitable for every ACL injury. Activities involving sudden twisting, pivoting, jumping, or high impact may increase knee instability or aggravate associated injuries.
The goal is to stay active while protecting the injured knee and following an appropriate rehabilitation plan. Patients can also learn about ACL tear treatment options before deciding on further treatment.
What Exercises Are Safe With an ACL Injury?
The appropriate exercises depend on the injury and stage of recovery. Common low-impact exercises used during ACL rehabilitation may include:
1. Straight Leg Raises
Straight leg raises can help strengthen the quadriceps while keeping the knee in a controlled position.
They may help:
- Maintain thigh strength
- Reduce muscle weakness
- Support knee function
2. Quadriceps Sets
Quadriceps sets involve tightening the thigh muscles while keeping the leg straight.
They can help activate the quadriceps and maintain muscle strength during rehabilitation.
3. Heel Slides
Heel slides involve gently bending and straightening the knee to work on mobility.
They may help:
- Improve knee movement
- Reduce stiffness
- Maintain range of motion
4. Stationary Cycling
Low-resistance stationary cycling may be included in rehabilitation when appropriate.
It can help maintain cardiovascular fitness while providing controlled knee movement with relatively low impact.
5. Swimming
Swimming and selected water-based exercises can provide conditioning while reducing the amount of weight placed on the knee.
The specific swimming technique and intensity should be discussed with your rehabilitation team.
6. Upper-Body and Core Exercises
Many upper-body exercises can be continued while protecting the injured knee.
Examples include:
- Seated dumbbell exercises
- Resistance-band exercises
- Seated shoulder exercises
- Selected core exercises
Exercises should be modified if they cause knee pain or instability.
What Exercises Should You Avoid With an ACL Injury?
High-impact and sudden-direction movements may place additional stress on an unstable knee. Until you have been assessed and cleared by your specialist, exercises and activities that may need to be avoided include:
Running and Sprinting
Running and sprinting can increase the forces placed on the knee and may be unsuitable when the ACL is injured or the knee remains unstable.
Jumping and Plyometric Exercises
Box jumps, repeated jumping, and other plyometric exercises can place significant loads on the knee and should generally be avoided until appropriate rehabilitation has been completed.
Cutting and Pivoting
Sudden changes in direction can place substantial stress on the ACL and are particularly important to avoid when the knee is unstable.
Deep Squats
Deep squats may place additional stress on the injured knee, particularly during certain stages of recovery. Your physiotherapist can determine whether squatting is appropriate and how deep you should go.
High-Impact and Contact Sports
Sports involving running, jumping, sudden direction changes, or physical contact may increase the risk of further knee problems.
Examples include:
- Football
- Basketball
- Rugby
- Volleyball
- Soccer
Return to these activities should follow appropriate assessment and rehabilitation. Patients with persistent instability may need to discuss ACL reconstruction surgery in Bangalore with an orthopaedic specialist.
What Are the Signs You Should Stop Exercising?
Stop an exercise if it causes significant or increasing symptoms. You should seek medical advice if you experience:
- Increased knee pain
- New or increasing swelling
- Knee locking
- Knee giving way
- Reduced range of motion
- Difficulty bearing weight
These symptoms may require further assessment to determine whether there is additional injury or another problem affecting the knee.
Why Is Professional Guidance Important for ACL Exercise?
ACL rehabilitation should be adjusted according to the injury, knee stability, muscle strength, symptoms, and recovery stage. A physiotherapist or orthopaedic specialist can help determine which exercises are appropriate and when activities can be progressed.
If rehabilitation is recommended, following a structured ACL rehabilitation plan can help patients progress safely while reducing unnecessary stress on the injured knee.
Do All ACL Injuries Require Surgery?
No, not every ACL injury requires surgery. Treatment depends on factors such as the extent of the tear, knee instability, associated injuries, activity requirements, and response to rehabilitation.
Some patients may be managed with rehabilitation and activity modification, while others with persistent instability or specific activity goals may require ACL reconstruction surgery.
When Should You See a Doctor for an ACL Injury?
You should consider an orthopaedic evaluation if you have persistent knee pain, swelling, instability, locking, difficulty walking, or repeated episodes of the knee giving way.
A specialist can assess the knee, review imaging when required, and determine whether rehabilitation, activity modification, or further treatment is appropriate.
Can You Work Out Without Making an ACL Injury Worse?
You may be able to continue exercising by choosing controlled, low-impact activities and avoiding movements that cause pain or instability. Exercise intensity should be increased gradually rather than returning immediately to running, jumping, pivoting, or sports.
If an activity repeatedly causes symptoms, stop it and discuss the problem with your rehabilitation or medical team.

Conclusion
You may be able to work out with an ACL injury, but exercise selection should be based on your injury severity, knee stability, symptoms, and stage of recovery. Low-impact strengthening and controlled mobility exercises may be appropriate, while running, jumping, pivoting, and contact sports may need to be avoided until the knee is adequately assessed.
The right approach depends on whether your ACL injury causes knee instability, whether the meniscus or other structures are affected, and what activities you want to return to. A proper orthopaedic evaluation can help determine whether rehabilitation alone is appropriate or whether ACL reconstruction should be considered.
Frequently Asked Questions
Can I walk with a torn ACL?
Many people can walk with an ACL tear, but walking ability varies depending on pain, swelling, knee stability, and associated injuries. If your knee repeatedly gives way, becomes swollen, or makes walking difficult, seek an orthopaedic assessment before increasing activity.
Can I do squats with an ACL injury?
Squats may be possible during rehabilitation, but the depth, resistance, and technique should match your injury and recovery stage. Deep or weighted squats may not be appropriate when the knee is painful or unstable. A physiotherapist can guide you on the appropriate squat variation.
What exercises are safe after an ACL injury?
Low-impact exercises such as straight leg raises, quadriceps sets, heel slides, stationary cycling, swimming, and selected upper-body exercises may be used during rehabilitation. The appropriate exercise depends on the injury and recovery stage, so exercises should be progressed under professional guidance.
Can exercise make an ACL injury worse?
Yes, certain activities can aggravate symptoms or increase stress on an unstable knee.
