What Non-Surgical Options Are Available for ACL Injuries?

Doctors may recommend activity modification, injections, bracing, and rehabilitation for certain ACL injuries instead of surgery. These treatments can help reduce pain, improve knee function, and restore stability. However, your orthopedic specialist will recommend the most appropriate treatment based on your injury severity, symptoms, and activity level.

At Total Orthopedics & Sports Medicine, our knee specialist, Dr. Michael Shindle, performs a thorough evaluation to determine whether you are a good candidate for non-surgical treatment. Then, he develops a personalized treatment plan that may include bracing, injections, and other non-surgical therapies. Throughout your recovery, he monitors your progress closely and adjusts your treatment to help you regain strength, stability, and safe movement. Call 855-321-6784 to book your appointment.

What Are the Most Effective Non-Surgical ACL Options?

The most effective non-surgical ACL treatments include activity modification, functional bracing, platelet-rich plasma (PRP) injections, pain-relieving medications, and neuromuscular training. Depending on your condition, your treatment plan may also include balance and proprioception training, electrical stimulation, swelling management, and progressive strengthening exercises.

Because each treatment targets a different aspect of recovery, our orthopedic specialist may combine several approaches to improve knee stability and restore knee function. Here is how these non-surgical treatments work and support your recovery after an ACL injury:

Activity Modification

Activity modification helps prevent repeated stress on your injured ACL while it begins to recover. Instead of stopping all movement, you temporarily avoid activities that involve pivoting, jumping, cutting, or sudden changes in direction. At the same time, your doctor encourages low-impact exercises that maintain mobility without placing excessive force on the knee. As your symptoms improve, you gradually return to more demanding activities under professional guidance. This reduces the risk of worsening the injury and further damage while allowing the surrounding muscles to stay active.

Functional Bracing

A functional knee brace provides extra support when your ACL cannot fully stabilize the joint. It limits excessive forward movement of the tibia and helps you feel more secure during walking or light recreational activities. Although a brace does not heal the torn ligament, it can improve movement and reduce flare-ups of the knee pain. Doctors often recommend it during recovery or when you return to selected activities.

Platelet-Rich Plasma (PRP) Injections

Platelet-rich plasma (PRP) uses a concentrated sample of your own blood that contains a higher level of platelets and natural growth factors. Once injected, these biological factors may help support the body’s natural healing response around the knee and the injured tissue.

A 2024 review published in Frontiers reported that PRP may support the biological healing environment after ACL injury by delivering concentrated growth factors. However, the review also reports that clinical outcomes remain inconsistent, and PRP benefits selected patients rather than all ACL tears. For this reason, orthopedic specialists usually combine PRP with rehabilitation instead of using it as a stand-alone treatment.

Pain-Relieving Medications

Pain-relieving medications help control discomfort, making it easier for you to stay active during rehabilitation. Depending on your symptoms, your doctor may recommend acetaminophen or a short course of nonsteroidal anti-inflammatory drugs (NSAIDs).

However, these medications only manage pain and inflammation; they do not heal the injured ACL. Therefore, doctors use them to improve comfort while you continue exercises that restore strength, mobility, and knee stability. Your orthopedic specialist will also consider your medical history, existing medications, and individual circumstances before recommending the safest option.

Neuromuscular Training

Neuromuscular training improves the communication between your brain and the muscles around the knee that control knee movement. It teaches your body to maintain proper alignment during standing, walking, landing, and changing direction.

This training often includes controlled balance, coordination, and movement drills that safely improve your stability. Better movement control reduces unnecessary stress on the knee during everyday activities. It also prepares you for more advanced strengthening exercises later in recovery.

Balance and Proprioception Training

After an ACL injury, your ability to sense joint position often declines. Balance and proprioception exercises retrain this awareness through carefully controlled movements on stable and unstable surfaces. As your coordination improves, your body reacts more quickly to unexpected movements. This helps reduce episodes of knee instability during daily activities.

Electrical Stimulation

Electrical stimulation uses gentle electrical impulses to activate muscles that become weak after an ACL injury. It is particularly helpful when pain or swelling prevents you from contracting the quadriceps effectively.

Early muscle activation also helps reduce strength loss while you continue other exercises, preserving muscle strength during recovery. As voluntary muscle control improves, doctors gradually reduce its use. A best-evidence synthesis of systematic reviews found moderate-certainty evidence that adding NMES to rehabilitation improves quadriceps strength.

Swelling Management

Controlling swelling early creates a better environment for recovery and makes movement more comfortable. Doctors often recommend ice, compression, and NSAIDs during the initial stage of healing. Reducing swelling can also improve muscle activation and make recovery exercises easier to perform. However, persistent swelling may limit knee motion, reduce mobility, and slow your recovery if left untreated.

Progressive Strengthening Exercises

Progressive strengthening rebuilds the muscles that support and protect your knee throughout recovery. Your exercise program usually begins with simple controlled exercises before advancing to more demanding movements as your strength improves. This steady progression follows your symptoms instead of a fixed timeline to reduce the risk of setbacks.

Stronger quadriceps, hamstrings, gluteal muscles, and core muscles also improve joint control during daily activities and sports. Moreover, continued strengthening helps strengthen the muscles that stabilize your knee during higher-demand activities.

Blood Flow Restriction (BFR) Training

Blood flow restriction (BFR) training allows patients to build muscle strength using lighter weights while partially restricting blood flow with a specialized cuff. This approach is particularly helpful when heavy resistance exercises are not safe after an ACL injury. As your recovery progresses, the intensity of your exercises gradually increases without placing unnecessary stress on the healing knee. This helps improve overall function before returning to higher-level activities.

Can an ACL Injury Heal Without Surgery?

Yes, some ACL injuries can recover without surgery if the knee remains stable. A structured non-surgical treatment plan can improve strength, restore function, and help you return to many daily activities. However, your orthopedic specialist will assess your knee, activity level, and recovery goals to determine whether non-surgical treatment is appropriate.

In fact, a secondary analysis of the KANON trial published in the British Journal of Sports Medicine found that some patients treated with rehabilitation alone showed MRI evidence of ACL healing. Those whose ligaments appeared healed on MRI also reported better knee symptoms and quality of life than patients without evidence of healing. Another systematic review reported that structured rehabilitation achieved outcomes comparable to early ACL reconstruction in selected patients with isolated ACL tears.

Who Is the Best Candidate for Non-Surgical Treatment?

Individuals with partial ACL tears, stable knee function, and realistic activity goals generally benefit the most from non-surgical treatment. They often regain strength and function through a structured non-surgical treatment plan without needing surgery. However, the final decision depends on a detailed orthopedic evaluation.

Our orthopedic specialist, Dr. Michael Shindle, also evaluates the following factors before determining your candidacy for non-surgical treatment:

• Age and Overall Health: Both younger and older adults may qualify, depending on their overall health and healing potential.
• Activity Level: Recreationally active individuals usually respond better than those who regularly participate in pivoting or contact sports.
• Occupation: People with sedentary or light-duty jobs often manage well without surgery, while physical jobs may require greater knee stability.
• Frequency of Knee Giving Way: Minimal or no episodes of knee instability during routine movements improve the chances of successful non-surgical recovery.
• Associated Knee Injuries: The absence of significant meniscus, cartilage, or other ligament injuries improves the chances of success.
• Response to Early Rehabilitation: Early improvements in strength, stability, and knee function during the initial recovery phase suggest that non-surgical treatment is working well.
• Commitment to Rehabilitation: Consistently following your exercise program and activity restrictions is essential for achieving the best possible outcome.

Although not every ACL injury requires surgery, waiting too long to choose the right treatment can affect your recovery. Dr. Michael Shindle carefully evaluates your injury to determine whether non-surgical care can help you achieve your goals without compromising knee stability. If you are a suitable candidate, he creates a structured treatment plan that supports every stage of your recovery. Contact us to book your consultation.

How Do Doctors Choose the Right ACL Treatment?

Dr. Michael Shindle chooses the right ACL treatment by identifying the cause of your knee instability. Instead of focusing only on the torn ligament, he also evaluates joint stability, muscle control, associated injuries, and your daily physical demands. This thorough assessment helps determine whether you can recover successfully without surgical intervention or reconstruction.

In addition, Dr. Michael Shindle carefully reviews the following factors before recommending treatment:

• Injury Mechanism: Identifies whether your ACL injury resulted from a twisting movement, direct impact, or a sports-related incident.
• Symptom Pattern: Reviews when your pain, swelling, instability, or knee locking occurs and how it affects your daily activities.
• Knee Range of Motion: Measures how well your knee bends and straightens to identify stiffness or limited movement.
• Diagnostic Imaging Tests: Reviews X-rays and MRI scans to confirm the ACL injury and identify any bone bruises, meniscal tears, cartilage damage, or other damaged ligament structures.
• Lower Limb Alignment: Evaluates your leg alignment and biomechanics because abnormal loading can affect treatment decisions and recovery.
• Overall Health: Reviews your age, medical conditions, medications, and healing potential to determine the safest treatment approach.
• Recovery Expectations: Explains the benefits, limitations, recovery timelines, and expected outcomes of each treatment option so you can make an informed decision.

Which Activities Should You Avoid During Recovery?

During ACL recovery, you should avoid running, jumping, pivoting, cutting, contact sports, heavy lifting, and sudden twisting movements. These activities place excessive stress on your healing knee and may increase the risk of reinjury or delayed recovery. Instead, follow your rehabilitation program and return to higher-impact activities only after your orthopedic specialist confirms that your knee is stable.

You should also be cautious with the following everyday movements during your recovery:

• Repeated Stair Climbing: Increases stress on your healing knee.
• Deep Squatting or Kneeling: Places extra pressure on the knee joint.
• Getting Up From Low Chairs: Requires greater knee strength and control.
• Standing for Long Periods: Increases pain and swelling.
• Walking on Uneven Ground: Raises the risk of twisting your knee.
• Quick Direction Changes: Can strain your healing anterior cruciate ligament.
• Using Ladders or Step Stools: Requires good balance and knee stability.
• Carrying Heavy Objects: Can overload your recovering knee, especially during the first few days of rehabilitation.

How Long Does Non-Surgical Recovery Take?

Non-surgical ACL recovery typically takes between 3 and 9 months, depending on the severity of your injury, knee stability, and commitment to rehabilitation. For example, initial return to daily activities may take 2 to 6 weeks, while full ACL tear recovery without surgery often requires a longer recovery period. Instead of following a set timeline, your orthopedic specialist will guide your recovery based on your knee function.

A PubMed study reports that nealy 60% of patients treated with rehabilitation alone achieved successful 2-year outcomes with knee function. Similarly, the NACOX prospective cohort study found that most patients treated without ACL reconstruction returned to sport in an average of 3.5 months, compared with 8.1 months after ACL reconstruction. Overall, 72% of the non-surgical group had returned to sport within 24 months.

What Should You Expect During Follow-Up Visits?

During your follow-up visits, Dr. Michael Shindle monitors your recovery and adjusts your treatment plan as your knee strength improves. He evaluates your strength, stability, range of motion, and recovery response at each appointment. Based on these findings, he guides you on when you can safely progress to more advanced exercises and daily activities.

During these visits, our knee specialist, Dr. Michael Shindle, also evaluates for minor changes that may affect your long-term recovery, including:

• Compensatory Movement Patterns: Identifies whether you’re unconsciously shifting weight to protect the injured knee.
• Muscle Imbalances: Detects weakness between the quadriceps, hamstrings, and hip muscles that may affect knee stability.
• Persistent Swelling: Determines whether ongoing inflammation is slowing your recovery.
• Functional Confidence: Assesses whether hesitation or fear of movement is limiting your recovery despite physical improvement.
• Exercise Technique: Ensures you perform exercises correctly to maximize results and reduce unnecessary stress on the knee.
• Readiness for Higher-Level Activities: Confirms your knee can safely tolerate increased physical demands before advancing your program.

One of the most common concerns patients share is not knowing whether their recovery is progressing normally or if something has gone wrong. Dr. Michael Shindle carefully evaluates your progress at every stage to identify problems before they become long-term setbacks. If your knee is not improving as expected, he can modify your treatment plan to address the specific factors delaying your recovery. Call 855-321-6784 to schedule an evaluation.

What If Non-Surgical Treatment Doesn’t Work?

If your knee remains unstable or fails to recover with non-surgical treatment, our orthopedic specialist may recommend surgery. He carefully evaluates your knee function, stability, symptoms, and rehabilitation progress to understand what is limiting your recovery. According to the KANON trial, about 39% of patients treated with rehabilitation eventually required surgery to reduce the risk of further injury.

Depending on your injury pattern and recovery goals, Dr. Michael Shindle may recommend one of the following surgical procedures:

• ACL Repair: Reattaches the torn ligament in carefully selected patients with suitable tear patterns.
• Meniscus Repair: Repairs a torn meniscus to improve knee function and preserve joint health.
• Cartilage Restoration: Treats damaged cartilage to reduce pain and improve joint function.
• Combined Ligament Reconstruction: Reconstructs multiple injured ligaments to restore overall knee stability.
• ACL Reconstruction: Replaces the torn ACL with a tendon graft, commonly taken from the patellar tendon or hamstring tendon, to restore knee stability.

What Patterns Have We Observed in Patients Who Successfully Avoid ACL Surgery

At our clinic, we have observed that successful non-surgical recovery depends on how your knee responds to treatment over time, not just on the initial diagnosis. While every ACL injury is different, patients usually share the following similar recovery patterns:

• Commitment to Recovery Plan: Consistently following prescribed exercises even after their symptoms begin to improve.
• Realistic Activity Progression: Returning to sports and higher-impact activities gradually based on knee stability and recovery progress.
• Improving Knee Stability: Fewer episodes of the knee giving way as strength, balance, and movement control improve.
• Steady Recovery Progress: Building strength, mobility, and function step by step without advancing too quickly.
• Regular Follow-Up Care: Attending scheduled visits helps us monitor progress, adjust your recovery plan, and address concerns early.

Although these patterns do not guarantee that surgery can be avoided, they often indicate that the knee is responding well to conservative treatment. Throughout your recovery, our team continuously monitors your progress and adjusts your treatment plan as needed to keep it aligned with your symptoms, activity level, and long-term goals.

Do Partial and Complete ACL Tears Need Different Treatment?

Yes, partial and complete ACL tears often require different treatment approaches. Partial tears may respond well to structured rehabilitation if the knee remains stable. On the other hand, complete tears may require surgery if instability persists, although not everyone with a complete tear needs immediate reconstruction. Your orthopedic specialist will recommend treatment based on your knee function, symptoms, activity level, and recovery goals.

Here is how partial and complete ACL tears compare in terms of severity, knee stability, and treatment:

Partial ACL Tear	Complete ACL Tear
Some ACL fibers remain intact	The ACL is completely torn
The knee may remain stable	The knee has a higher risk of instability
Lower risk of repeated giving way	Higher risk of recurrent instability
Treatment depends on symptoms and function	Treatment depends on instability and activity goals

In addition, a partial ACL tear can progress to a complete tear if your knee repeatedly gives way or you return to high-impact activities before it has regained adequate strength and stability. Recurrent instability places additional stress on the remaining ligament fibers and surrounding knee structures. Following your rehabilitation program and attending regular follow-up visits helps reduce this risk while allowing your orthopedic specialist to monitor your recovery closely.

Can an Untreated ACL Injury Damage Your Knee?

Yes, an untreated ACL injury can lead to additional damage within your knee over time. Ongoing knee instability may increase stress on the meniscus, cartilage, and other supporting structures, particularly during twisting or pivoting movements. However, early evaluation and appropriate treatment help reduce the risk of long-term joint damage and preserve knee function.

Will an ACL Tear Lead to Knee Arthritis?

Yes, an ACL tear increases the risk of knee arthritis because it can alter how forces are distributed across the joint. This abnormal loading may gradually wear down the joint surfaces over time, particularly when additional cartilage or meniscal injuries are present.

A 2022 PubMed review and meta-analysis found that an ACL injury increased the odds of developing knee osteoarthritis nearly sevenfold compared with an uninjured knee. The authors also found that the increased risk persisted regardless of whether patients underwent ACL reconstruction or received non-surgical treatment.

Can You Return to Sports Without ACL Surgery?

Yes, returning to sports without ACL surgery is possible for patients with good knee stability and successful recovery. However, low-impact sports are generally safer than activities that involve cutting, frequent pivoting, jumping, or sudden changes in direction. Your orthopedic specialist will guide your return based on your strength, stability, and movement quality.

The following sports are generally considered safer for patients who successfully recover with non-surgical ACL treatment:

• Walking
• Hiking
• Cycling
• Swimming
• Golf
• Rowing
• Elliptical Training
• Light Jogging

Note: Although these sports place less stress on the ACL, you should return to the previous level of activity only after your orthopedic specialist confirms that your knee has regained adequate strength.

How Can You Prevent Another ACL Injury?

You can help prevent another ACL injury through ongoing strength training, neuromuscular exercises, balance training, and proper movement techniques. These strategies improve knee control during sports and everyday activities. Continuing your ACL prevention program after recovery also helps lower the risk of future injuries.

In addition to structured training, several daily habits also play an important role in protecting your ACL. For example, wearing appropriate footwear, gradually increasing your training intensity, and allowing enough time for recovery help reduce unnecessary stress on your knee. Similarly, addressing minor injuries, knee pain, or swelling early and avoiding a return to sports before receiving medical clearance can lower the risk of another ACL injury.

Which Exercises Help Protect Your ACL?

Quadriceps strengthening, hamstring strengthening, gluteal strengthening, balance exercises, plyometric training, and agility drills are the most effective exercises for protecting your ACL. They improve knee stability, movement control, and lower-limb strength. As your strength improves, your orthopedic specialist will safely advance these exercises or weight bearing to match your recovery progress.

To continue your recovery safely, follow our Knee Conditioning Program. This guide includes step-by-step exercises designed to improve strength, flexibility, balance, and knee stability throughout your recovery. It also provides clear instructions on when to progress each exercise, helping you strengthen your knee over time. If you need personalized guidance or your recovery is not progressing as expected, contact us to schedule an appointment with our orthopedic specialist.

Which Sports Carry the Highest Risk of Reinjury?

Sports that involve frequent pivoting, cutting, jumping, and sudden changes in direction carry the highest risk of ACL reinjury. Common sports include soccer, basketball, football, rugby, handball, and skiing because they place repeated stress on the knee during high-demand movements. A systematic review also found that younger athletes who returned to high-risk cutting-and-pivoting sports had a secondary ACL injury rate of approximately 23%.

Moreover, the risk is not limited to your previously injured knee. After returning to sports, some athletes also experience an ACL injury in the opposite knee because both legs are exposed to similar physical demands. Because of this, your recovery plan should focus on restoring equal strength, stability, and movement control in both legs before you return to sports.
