An ACL (anterior cruciate ligament) injury is often an athlete’s worst nightmare. Whether you’re a weekend warrior, a high school/college/professional athlete, a lifter, a runner, or a winter sports fanatic, tearing your ACL can put the brakes on your game. ACL injuries happen suddenly, but the road to recovery doesn’t have to be a straight line. The good news? With the right approach to surgery and physical therapy (PT), you can not only return to the sports you love but perform even better than before.
Here at The Charlotte Athlete, we specialize in helping you do just that. This guide is designed to give you a comprehensive look at ACL injuries, surgery, and how physical therapy can get you back to your active life. We’ll explain everything from understanding the demands on your knee during sports to the specific PT protocols we use to get you back on the field. So, sit tight – we’ve got a lot to cover!
Who Are We at The Charlotte Athlete and What Makes Us Different?
At The Charlotte Athlete, we’re not just another physical therapy clinic. We are a team of highly skilled professionals who specialize in getting athletes back to their best. Whether you’re dealing with a torn ACL or recovering from another injury, we focus on what matters most—your return to sport and performance.
What sets us apart is our criterion-based approach to recovery. While other clinics may focus on a set timeline (say, “You’ll be back in 6-9 months”), we understand that every athlete is different. Your recovery time should be based on meeting specific functional milestones rather than just the calendar. So, if you’re ahead of the game, we’re not going to hold you back just because it’s “Week 8.” Likewise, if you’re not quite ready, we’ll take the time to make sure you’re hitting all the right marks before you jump back into action. This is crucial for ACL recovery! Rushing back too soon could risk re-injury.
If you are curious about a little bit more detail regarding our stages of progression in the rehab process and why who you have in your corner is vital for your recovery, follow this link to learn more! Now, let’s jump into how various sports put “demands” on the ACL.

The Demands on the Knee/ACL from Various Sports
Let’s talk about what the ACL is and why it matters so much in the first place. The ACL, aka the Anterior Cruciate Ligament, is one of the key ligaments in the knee, as it plays a crucial role in stabilizing the knee joint. The ACL helps prevent the tibia from sliding too far forward relative to the femur and also controls rotational movements of the knee. As you can imagine, this becomes especially important, during activities like running, jumping, decelerating, cutting, and pivoting. It’s crucial for sports like basketball, soccer, football, and skiing, where rapid changes in direction or high-impact movements are the norm.
For example:
- Basketball: Jumping, cutting, and quick pivots put tremendous stress on the knee. The twisting and turning involved in a layup or blocking a shot often test the stability of the ACL.
- Soccer: Sudden stops, changes of direction, and high-speed sprints during ball control or tackling can lead to ACL injuries.
- Football: Similar to soccer, football players often experience contact that can cause a tear, especially during tackles and sudden movements in high-intensity situations.
- Skiing: Skiers and snowboarders are prone to ACL injuries due to the combination of high speeds, sudden movements, and those not-so-fun awkward falls.
Think about the ACL being like the “backbone” of your knee joint—keeping everything in place during all of those high intensity movements. When it tears, it’s like trying to drive a car with no steering wheel—you’re still moving, but you don’t have much control.
Potential Injuries That Cause A Tear
While most individuals think of ACL tears occurring from an on-field tackle to the knee, or some type of “dramatic” instance, ACL tears can also occur from smaller, seemingly “insignificant” movements. Actually, this is the most common way that an athlete tears their ACL. Think about JuJu Watkins from USC just running down the court and taking a step into the paint for an upcoming layup, and she just goes down. This is a great example of when you look at the TV screen.. Like what in the world just happened? That one step led to one of the top female collegiate basketball players to be out for the season due to this exact injury.
Let’s break down the common ways a tear to this ligament happens:
- Non-contact injuries: These occur when an athlete is changing direction, decelerating, or landing from a jump. For example, if you’re planting your foot to pivot and your knee buckles inward, that could lead to an ACL tear. THIS IS THE MOST COMMON!
- Direct contact: A sudden blow to the knee, such as from a tackle or collision, can cause the ACL to tear.
Overuse or wear-and-tear: Sometimes, ACL injuries are a result of repeated stress on the knee, particularly if the athlete isn’t allowing enough time for rest and recovery between intense training or game days.

Surgical Options and How It Changes Rehab Approach
Now, let’s dive into the big question: Do you need surgery? The decision to go under the knife depends on several factors, including the severity of the tear, your sport, and how active you are in your daily life. There are instances where some athletes display adequate dynamic stability of the knee and can compensate for the ACL being “deficient”. We term these athletes as “copers”. However, this is not super common, as almost 80% of athletes undergo surgery after this type of injury.
Here’s a rundown of the surgical options available for ACL tears:
- Autograft Surgery (using your own tissue): This is the most common surgery for ACL tears. Surgeons usually take a piece of your hamstring or patellar tendon to reconstruct the ACL. This option has a good success rate and avoids rejection issues since it’s your own tissue.
- Allograft Surgery (using a donor tendon): In cases where autograft isn’t feasible (such as if there’s a significant amount of tissue damage or you’re older and less active), surgeons may opt for an allograft from a tissue bank. While the risk of rejection is low, there’s a slightly longer recovery time.
- Synthetic Grafts: Sometimes, synthetic materials are used to replace the ACL. This is a less common option, but it might be considered in certain situations.
How does surgery change rehab? The type of surgery you undergo will impact the specifics of your rehab program. For instance, an autograft requires a longer healing time since the tissue used for reconstruction needs time to “set in.” However, at The Charlotte Athlete, regardless of the surgery type, we tailor the rehab process to help you get back to your peak performance in the sport that you love!
What Does PT at The Charlotte Athlete Look Like?
Physical therapy at The Charlotte Athlete isn’t just about lying on a table and getting your weekly massage (though we do utilize a good amount of manual therapy work— but… this may look a little different). We approach PT with a combination of education, hands-on work, and structured exercises that help you rebuild strength, stability, and functionality. Let’s break it down:
Education
You’ve probably heard the saying, “Knowledge is power,” and we couldn’t agree more. From day one, we prioritize educating you about your injury, the recovery process, and what’s required to get you back to your “old athletic self”. At The Charlotte Athlete, our team will take the time to walk you through the biomechanics of your ACL injury, so you understand exactly how it happened and why we’re doing the exercises we’re doing. We also focus on educating you about proper body mechanics to help mitigate re-injury down the road. Research shows that about 45% of athletes never return to their previous level of sport, and 1 in 3 athletes either retear their same ACL or tear their opposite ACL. Where you go for rehab matters.
Manual Therapy
Manual therapy is a key part of the rehab process. This includes hands-on techniques to reduce pain, improve mobility, and help your tissues heal. Our skilled therapists may use soft tissue mobilization, joint mobilizations, or other techniques to improve the function of the knee joint. If your knee is stiff or swollen post-surgery, manual therapy can help accelerate recovery by gradually restoring flexibility, mobility, and movement patterns, as well as allowing you to regain normal joint movement and prevent stiffness.

Exercise Focus and Examples for Each Stage of Rehab
At The Charlotte Athlete, rehab is broken down into stages; however, as I mentioned above, The timelines are NOT SET IN STONE. Every athlete is different, which is why we focus more on criteria VERSUS time in order to get the best results. Here’s an example of what each stage could look like:
Early Stage (0-6 weeks post-surgery)
The focus here is on pain management, swelling control, and regaining full knee extension. THIS TIME FRAME IS ONE OF THE MOST IMPORTANT TIME POINTS IN YOUR REHAB PROCESS. If your rehab is lacking quality in these first few weeks, this will only set the stage for a poor foundation later down the road. Some exercises might include:
- Quad sets
- Straight leg raises
- Heel slides
- Stationary bike & unloaded squatting (total gym)
Mid-Stage (6-12 weeks post-surgery)
As you regain motion and your walking pattern normalizes, we’ll start working on strengthening the muscles surrounding the knee to improve stability. Even though strengthening starts in the initial stages of rehab, we are able to get a little more functional at this point. Exercises might include:
- Squat variations
- Lunge variations
- Step downs
- Knee over toe eccentric control drills
Late Stage (3-6 months post-surgery)
At this point, you’ll begin more sport-specific movements. The goal is to return to jogging – and later cutting, pivoting, and explosive movements without risking injury. Exercises include:
- Jogging: WAHOO!!
- Deceleration: To teach your body how to control your movements.
- Squat Jumps: To build explosive strength.
- Lateral bounds: Improve your ability to change directions quickly.
Return-to-Sport Stage (6-12 months)
This is the fun part—getting you back into your sport! We’ll do plyometric drills, agility drills, and running progressions SPECIFIC TO YOUR SPORT to ensure you’re ready to perform at the highest level.
