ACL (Anterior Cruciate Ligament) and PCL (Posterior Cruciate Ligament) tears are two of the most common and serious injuries to the knee, especially for athletes and physically active individuals.
While surgery is often recommended for complete tears of these ligaments, non-surgical treatment options are increasingly being explored and considered, particularly for those with partial tears, less active individuals, or those looking to avoid surgery for personal or medical reasons. Non-surgical approaches can focus on rehabilitation, strengthening the surrounding muscles, and utilizing supportive devices to help restore function and stability in the knee.
This guide examines the non-surgical treatment options for ACL and PCL tears, offering insight into rehabilitation strategies, the role of physical therapy, and how functional bracing and alternative therapies can aid recovery.
We will also discuss the role of lifestyle adjustments and how non-surgical management can help individuals maintain a high quality of life while avoiding the risks and complications associated with surgical interventions.
Understanding the Importance of Rehabilitation
Initial Rehabilitation After an ACL or PCL Tear
Rehabilitation is the cornerstone of non-surgical treatment for ACL and PCL tears. The main goal of rehabilitation is to restore as much strength, stability, and range of motion as possible in the injured knee, while minimizing pain and inflammation. For many individuals with partial tears or those who are not candidates for surgery, rehabilitation offers a viable pathway to recovery.
The initial phase of rehabilitation focuses on controlling pain and inflammation, protecting the knee from further injury, and beginning gentle range of motion exercises. At this stage, individuals may experience significant swelling and discomfort, which can be managed through rest, ice, compression, and elevation (RICE). Nonsteroidal anti-inflammatory drugs (NSAIDs) are also commonly prescribed to reduce pain and swelling.
During the early stages of rehabilitation, physical therapy is crucial. A physical therapist will guide the patient through a series of exercises designed to restore mobility in the knee joint. These exercises typically begin with passive movements, where the therapist helps move the knee through its range of motion, gradually progressing to active movements that the patient performs on their own.
In addition to mobility exercises, strength training for the surrounding muscles is introduced early in the rehabilitation process. Strengthening the quadriceps, hamstrings, glutes, and calf muscles helps compensate for the loss of stability in the knee due to the ligament tear. This approach is essential in preventing further injury and enabling the patient to regain functional movement.
Rehabilitation may also include balance and proprioception exercises. These exercises are designed to improve the patient’s ability to sense the position and movement of their knee, which is often impaired following a ligament tear. Rebuilding proprioception is important for preventing falls and enhancing the patient’s ability to perform everyday activities.
The early phase of rehabilitation is crucial for setting the foundation for long-term recovery. By addressing pain, swelling, mobility, and strength, individuals can begin the process of healing and restoring function to their injured knee.
Progressive Strengthening and Functional Training
As rehabilitation progresses, the focus shifts from pain management and basic mobility exercises to more advanced strengthening and functional training. This phase is essential for restoring the knee’s stability and preparing the patient to return to their regular activities, whether that involves sports, work, or daily living tasks.
Progressive strengthening exercises target the muscles surrounding the knee, particularly the quadriceps and hamstrings, which play a critical role in stabilizing the knee joint. These exercises may include leg presses, squats, lunges, and step-ups, all of which help to rebuild muscle mass and improve the knee’s ability to support weight. In addition, strengthening the core and hip muscles is important for overall lower-body stability.
Functional training exercises are also introduced during this phase of rehabilitation. Functional training focuses on movements that mimic the activities the patient performs in their daily life or in their sport. For athletes, this may include sport-specific drills such as running, jumping, or cutting movements. For non-athletes, functional training might focus on walking, climbing stairs, or lifting objects.
Balance and proprioception training remains a key component of rehabilitation during this phase. Exercises such as single-leg stands, balance boards, and agility drills help improve the patient’s coordination and ability to control their knee movements. These exercises reduce the risk of re-injury and prepare the patient to return to activities that require dynamic movement.
As the patient gains strength and confidence in their knee, the intensity of rehabilitation exercises is gradually increased. This progressive approach ensures that the knee is challenged enough to stimulate recovery without being overstressed. Regular monitoring by a physical therapist is important to ensure that the patient is progressing safely and effectively.
The goal of this phase of rehabilitation is to restore full strength, stability, and functional capacity to the knee. By the end of this phase, many patients are able to return to their normal activities with minimal pain and a reduced risk of re-injury.
Maintenance and Long-Term Rehabilitation
Even after the initial recovery period, long-term rehabilitation is crucial for preventing future knee injuries and maintaining the health of the injured ligament. Maintenance rehabilitation involves ongoing exercises and activities that help keep the knee strong, stable, and functional over the long term.
For athletes, maintenance rehabilitation may involve continuing with sport-specific drills, strength training, and flexibility exercises on a regular basis. This ongoing training helps ensure that the muscles surrounding the knee remain strong and capable of supporting the joint during high-impact activities. In addition to strength training, athletes may also incorporate plyometric exercises and agility drills into their maintenance routine to improve their knee’s ability to handle sudden changes in direction and speed.
For non-athletes, maintenance rehabilitation may focus on daily activities that help maintain strength, flexibility, and balance in the knee. Regular walking, swimming, cycling, or yoga can help keep the knee joint healthy and prevent stiffness or weakness from developing over time. In addition to regular physical activity, patients should continue with targeted exercises that strengthen the quadriceps, hamstrings, and other key muscle groups that support the knee.
Physical therapy check-ins are often recommended during the maintenance phase of rehabilitation. These check-ins allow patients to receive guidance on their exercise routine and address any lingering issues or concerns. In some cases, patients may require adjustments to their rehabilitation program as they continue to recover and adapt to their injury.
Long-term rehabilitation and maintenance are essential for ensuring that the knee remains strong and functional over time. Without ongoing care, individuals are at greater risk of developing chronic instability or re-injury, particularly if they return to high-impact activities too quickly or without adequate preparation.
By committing to a long-term rehabilitation plan, individuals can protect their knee health and reduce the likelihood of future ligament injuries.
The Role of Physical Therapy in ACL and PCL Recovery
The Initial Role of Physical Therapy
Physical therapy is a fundamental component of non-surgical treatment for ACL and PCL tears, providing structured, personalized rehabilitation that helps individuals regain mobility, strength, and confidence in their knee.

Certain movements or behaviors, such as sudden twisting or pivoting, can place undue stress on the injured ligament and hinder the healing process. By making thoughtful adjustments to their daily routines, individuals can protect their knees and promote recovery.
During the early stages of recovery, individuals may need to avoid weight-bearing activities and use crutches or a knee brace to reduce stress on the injured leg. As they progress in their rehabilitation, they can gradually reintroduce these activities but should avoid movements that involve sudden changes in direction, jumping, or other high-impact actions.
Making adjustments to how individuals perform basic tasks, such as walking, climbing stairs, or lifting objects, can also help protect the knee during recovery. These modifications may include taking shorter steps, using handrails for support, and distributing weight evenly between both legs when lifting heavy objects.
By making these modifications, individuals can reduce the risk of re-injury and support the healing process.
Staying Active During Recovery
While it is important to protect the knee from excessive stress during recovery, staying active is equally important for promoting healing and maintaining overall health. Low-impact exercises, such as swimming, cycling, and yoga, can help individuals stay fit while minimizing the risk of further injury to the knee.
Staying active during recovery also helps prevent muscle atrophy, improve circulation, and promote flexibility, all of which are essential for a successful recovery. Physical therapists often recommend specific exercises and stretches that individuals can perform at home to support their recovery. These exercises focus on strengthening the muscles around the knee, improving balance and coordination, and increasing range of motion in the joint.
By staying active and engaged in their rehabilitation, individuals with ACL and PCL tears can promote healing, improve their knee function, and reduce the risk of future injuries.
Conclusion
Non-surgical treatment options for ACL and PCL tears offer a highly effective path to recovery for individuals who prefer to avoid surgery or have partial ligament tears.
Rehabilitation, which includes structured physical therapy, functional bracing, and sometimes alternative therapies such as PRP or stem cell treatments, helps restore the knee’s strength, stability, and overall function. These therapies are tailored to support the body’s natural healing processes while maintaining joint stability during recovery.
Lifestyle adjustments are also essential in this approach. Managing body weight reduces strain on the injured knee, and modifying daily activities helps prevent further damage while allowing the ligament to heal properly. Staying active with low-impact exercises promotes circulation, prevents muscle atrophy, and helps maintain overall fitness, all of which contribute to a successful recovery.
A commitment to working closely with healthcare providers and adhering to a personalized rehabilitation plan enables individuals to recover fully without the risks and complications associated with surgery. By incorporating these non-surgical treatments, patients can regain their mobility, strength, and quality of life.
This approach not only addresses immediate injury but also equips individuals with the tools and knowledge to protect their knee health in the long term, reducing the likelihood of future injuries and allowing them to confidently return to their normal routines and activities.
