The ACL (anterior cruciate ligament) is a strong band of tissue on the inside of your knee joint. The ACL connects your thighbone to your shinbone and plays a crucial role in helping to stabilize your knee. You can think of it like an internal rope that helps keep your knee from moving around too much. It keeps your shinbone from sliding too far forward relative to your thighbone. This can happen during sudden movements like:
Jumping
Pivoting
Changing direction
Without a healthy ACL, your knee joint wouldn’t be as stable, which could increase your risk of injuries and make everyday activities challenging.
ACL injuries are unfortunately quite common; ACLs are the most frequently injured ligament in the knee. Up to an estimated 200,000 people in the U.S. tear their ACL each year. Athletes, especially those involved in sports like soccer, football and basketball, are at a higher risk. ACL injuries are classified based on their severity:
Grade 1 — Least severe injury where the ACL is stretched but not torn
Grade 2 — Partial tear of the ACL where it’s stretched with some minor tearing
Grade 3 — Complete or near-complete tear of the ACL, making it nonfunctional
Understanding the severity of the ACL injury can help determine the appropriate treatment plan, which can include physical therapy.
Treatment options for ACL injuries
The best treatment for an ACL injury will depend on several factors:
Severity of your injury
Your age
Your activity level
Your overall health
For mild to moderate ACL tears, nonsurgical options may be considered for ACL recovery, especially for older individuals or those who have low activity levels. A nonsurgical approach to ACL recovery may involve a combination of rest, physical therapy and bracing. This approach may not be suitable for everyone.
When nonsurgical treatments aren’t enough to help restore knee stability, ACL reconstruction surgery may be needed. Reconstruction can help restore knee stability by using a graft taken from another tendon in the body. This graft replaces the torn ACL. The decision to undergo surgery is a personal one and should be made in consultation with your doctor.
Recovery timeline for ACL injury
It’s important to note that recovery times for an ACL injury can vary based on your individual factors, including if you have to have surgery or not. The average recovery time for an ACL injury is six to nine months.
Your recovery timeline without needing ACL reconstruction surgery may take longer than surgery recovery. The specific timeline can vary based on your:
ACL injury severity
Healing capacity
Rehab intensity
Generally, it can take six to nine months to recover from an ACL tear without surgery. It may also be possible for you not to achieve full recovery to return to high-impact activities.
Your recovery timeline from an ACL injury that requires surgery can vary due to a variety of factors:
Your age
Your overall health
The surgical technique
However, the recovery process can be divided into general phases that can follow a rough time frame:
Phase 1 — Immediate postsurgery
Focus on reducing pain and swelling and regaining basic knee motion
Using crutches, weight-bearing restrictions may initially apply
Gentle range-of-motion exercises begin
Phase 2 — Strengthening and endurance
Increased weight-bearing and range-of-motion exercises
Building strength in the quadriceps, hamstrings and calf muscles
Improving balance and coordination
Phase 3 — Return to function
Progressing to more advanced exercises, including plyometrics and agility drills
Gradual return to sports-specific activities
Focus on regaining confidence and neuromuscular control
Phase 4 — Return to sport or full activity
Full participation in sports and activities, with approval from your surgeon and physical therapist
Continued focus on strength, balance and proprioception
Overcome fear and anxiety about reinjury
It’s essential to follow your surgeon’s and physical therapist’s guidance throughout the recovery process. These are just general timelines, and your individual progress may vary.
Tips that can help boost your ACL injury recovery
Recovering from an ACL injury can be a challenging journey, but with the right approach, you can improve your chances of a full recovery. It’s essential to remember that everyone’s recovery journey is unique, and you should consult with your health care provider for personalized advice. It’s also important not to push too hard or too quickly. Here are some tips you can incorporate into your recovery journey to help your recovery process:
Physical therapy — Physical therapy can be the cornerstone of your recovery. Your physical therapist will create a program tailored to your specific needs and goals. They’ll guide you through exercises to regain strength, flexibility, balance and stability.
Cold therapy — Applying ice packs to your injured knee can help minimize inflammation, numb the area and reduce discomfort. Ask your doctor or physical therapist for specific ice application instructions.
Bracing — A knee brace can provide extra stability during your healing process by reducing the stress on your injured knee.
Rest — Getting enough rest is essential for healing. Allow your body sufficient time to recover. Pay attention to pain signals and adjust your activities accordingly.
Nutrition — Fueling your body with a balanced diet provides it with the nutrients it needs for tissue repair. Staying hydrated also helps support your overall recovery.
Working both sides — It’s important to work both sides during your ACL injury recovery, as it helps improve your overall body awareness and can prevent compensation injuries.
Risks of returning too soon from an ACL injury
Returning to sports or high-impact activities before your knee is fully healed can have serious consequences, including:
Chronic knee pain
Arthritis
Meniscus tear
Reduced performance
It’s important to prioritize a full recovery to help minimize your risks and promote long-term knee health. While you’re sure to be eager to return to full activity, patience and following your rehab plan are crucial.
