Can you work out with an ACL injury? Yes, many people can continue exercising after an ACL injury, but only with safe, low-impact exercises that do not place excessive stress on the knee.
What Is an ACL Injury?
The Anterior Cruciate Ligament (ACL) is one of the major ligaments that stabilizes the knee joint. ACL injuries commonly occur during sports, sudden twisting movements, jumping, or direct impact to the knee.
Depending on its severity, an ACL injury may be:
- Grade 1 (Mild Stretching)
- Grade 2 (Partial Tear)
- Grade 3 (Complete Tear)
The ability to exercise safely depends largely on the extent of the injury.
Can You Exercise with an ACL Injury?
In many cases, patients can continue certain low-impact exercises after an ACL injury. In fact, controlled exercise is often an important part of rehabilitation and recovery.
However, exercising without proper guidance can worsen knee instability and potentially cause additional damage to the meniscus, cartilage, or surrounding ligaments.
The goal is to stay active while protecting the injured knee.
Safe Exercises for an ACL Injury
1. Straight Leg Raises
Straight leg raises help strengthen the quadriceps muscles without placing excessive stress on the ACL.
Benefits:
- Improves thigh strength
- Supports knee stability
- Helps maintain muscle mass
2. Quadriceps Sets
This exercise involves tightening the thigh muscles while keeping the leg straight.
Benefits:
- Activates key knee-supporting muscles
- Improves strength after injury
- Reduces muscle weakness
3. Heel Slides
Heel slides help restore knee flexibility and range of motion.
Benefits:
- Improves mobility
- Reduces stiffness
- Supports recovery after injury
4. Stationary Cycling
Low-resistance cycling may be recommended during rehabilitation.
Benefits:
- Improves joint mobility
- Maintains cardiovascular fitness
- Places minimal impact on the knee
5. Swimming
Swimming and water-based exercises can provide excellent conditioning while reducing stress on the knee joint.
Benefits:
- Low-impact activity
- Improves overall fitness
- Supports joint movement
6. Core and Upper Body Exercises
Patients with ACL injuries can usually continue many upper-body and core-strengthening exercises.
Examples include:
- Seated dumbbell exercises
- Resistance band workouts
- Planks (if pain-free)
- Seated shoulder exercises
Maintaining overall fitness can help during recovery.
Exercises to Avoid with an ACL Injury
Certain exercises place significant stress on the ACL and should generally be avoided until cleared by a specialist.
Running and Sprinting
High-impact running can increase knee instability and worsen symptoms.
Jumping Exercises
Activities such as box jumps and plyometric drills place excessive force on the knee.
Cutting and Pivoting Movements
Sports that require sudden direction changes are among the most common causes of ACL injuries.
Deep Squats
Deep squatting can place additional stress on the knee joint, especially during the early recovery phase.
Contact Sports and High-Impact Activities
Patients should avoid sports such as:
- Football
- Basketball
- Rugby
- Volleyball
- Soccer
until proper healing or treatment has occurred.
Signs You Should Stop Exercising Immediately
Stop exercising and seek medical advice if you experience:
- Increased knee pain
- New swelling
- Knee locking
- Knee giving way
- Reduced range of motion
- Difficulty bearing weight
These symptoms may indicate worsening injury or additional damage.
Why Professional Guidance Is Important
Every ACL injury is different. Some patients may benefit from physiotherapy alone, while others may require ACL reconstruction surgery.
A personalized rehabilitation plan helps:
- Improve recovery
- Prevent further injury
- Restore strength safely
- Support return to sports
Working with an orthopaedic specialist and physiotherapist ensures exercises are appropriate for your condition.
Do All ACL Injuries Require Surgery?
Not necessarily.
Partial ACL tears and less active individuals may recover successfully with:
- Physiotherapy
- Strengthening exercises
- Activity modification
- Knee bracing
However, surgery may be recommended when:
- The ACL is completely torn
- Knee instability persists
- The patient wishes to return to sports
- Associated injuries are present
When Should You See a Doctor?
You should consult an orthopaedic specialist if you experience:
- Persistent knee pain
- Swelling after activity
- Knee instability
- Difficulty walking
- Repeated episodes of the knee giving way
- Reduced athletic performance
Early evaluation helps determine the safest treatment and rehabilitation approach.

Frequently Asked Questions About Working Out with an ACL Injury
Can you walk with a torn ACL?
Yes, many people can still walk with a torn ACL, but the knee may feel unstable and can give way during certain movements.
Can I squat with an ACL injury?
Deep squats should generally be avoided during the early stages of recovery because they can place additional stress on the injured knee.
What exercises are safe if I have a torn ACL?
Low-impact exercises such as straight leg raises, quadriceps sets, stationary cycling, swimming, and flexibility exercises are often considered safe. The best exercise program depends on the severity of the injury and should be guided by a healthcare professional.
Can exercise make an ACL injury worse?
Yes, performing the wrong exercises can worsen knee instability and increase the risk of additional damage to the meniscus or cartilage. This is why proper rehabilitation guidance is important.
Should I stop all physical activity after an ACL injury?
Not necessarily. Complete rest is rarely recommended for extended periods. Controlled rehabilitation exercises often play an important role in maintaining strength and supporting recovery.
Can I lift weights with an ACL injury?
Some weight-training exercises may be safe, especially for the upper body and core. Lower-body exercises should be modified to avoid excessive stress on the injured knee until approved by a specialist.
