An anterior cruciate ligament (ACL) tear is a common knee injury that can cause pain, swelling, and a feeling of instability. The ACL is one of the primary ligaments that stabilizes the knee during cutting, pivoting, and sudden directional changes. ACL injuries can occur during sports, exercise, or everyday activities involving twisting or abrupt movements.
At our Miami clinic, we provide a comprehensive, non-surgical approach to ACL tear treatment focused on accurate diagnosis, restoring knee stability, reducing symptoms, and helping patients return to activity while avoiding unnecessary surgery whenever possible.
The ACL is located in the center of the knee joint and helps prevent excessive forward movement and rotational instability of the tibia relative to the femur.
ACL injuries may range from:
Not all ACL tears require surgery, particularly in patients without significant instability or high athletic demands.
Symptoms of an ACL tear may vary depending on severity and activity level. Common symptoms include:
Some patients with partial tears may have subtle or intermittent symptoms.
ACL tears commonly occur due to:
Non-contact injuries are a frequent cause of ACL tears.
Accurate diagnosis requires correlating symptoms with physical examination findings and imaging results. Evaluation typically includes:
Detailed history and injury mechanism review
Physical examination assessing knee stability and ligament integrity
Gait and functional movement assessment
Review of prior imaging
MRI of the knee when clinically indicated which may also show concomitant meniscus tear
Imaging findings are interpreted alongside symptoms, as MRI abnormalities do not always predict functional limitation.
Many patients with ACL tears — especially partial tears or low-demand individuals — can be managed successfully without surgery.
Physical therapy is a cornerstone of non-surgical treatment and may focus on:
Rehabilitation programs are individualized based on goals and activity demands.
Treatment may include:
These strategies help reduce reinjury risk.
Medications may be used to help manage pain and swelling and may include:
Medications are used to support rehabilitation, not replace it.
In select cases, injections may be considered to help manage knee pain or inflammation associated with ACL injury:
These procedures are typically performed using image guidance to improve accuracy and safety.
In certain situations, biologic therapies such as platelet-rich plasma (PRP) and bone marrow aspirate concentrate (BMAC) which contains stem cells may be discussed as part of a comprehensive, non-surgical treatment strategy. These therapies are intended to support the joint environment and surrounding tissues rather than replace or reconstruct a torn ligament.
In select patients, bone marrow–derived therapies may be discussed as part of a comprehensive, non-surgical treatment strategy for ACL injuries.
Bone marrow contains a variety of cells and biologic factors that may help support the joint environment and surrounding tissues. When used appropriately, bone marrow–derived treatments are intended to address inflammation, joint health, and functional limitations rather than reconstruct or replace a torn ligament.
These therapies may be considered in cases such as:
Careful patient selection is essential. Treatment decisions are based on clinical examination, imaging findings, knee stability, activity level, and individual goals.
It is important to understand that bone marrow–derived therapies are not a substitute for ACL reconstruction in patients with severe instability or high-demand athletic requirements. Outcomes vary, and these treatments are used as part of a broader, individualized care plan.
Surgical reconstruction may be considered when:
Many patients are able to manage ACL injuries without surgery, particularly when instability is minimal. It is important to note that there is increasing evidence that surgery can be delayed without any long term effect on the results of surgery, so patients who choose to trial a non-surgical approach first can still benefit from surgery if it does not go as planned.
You may be a good candidate for a non-surgical approach if you:
Treatment plans are individualized based on knee stability, activity level, and long-term goals. One study of ACL repair versus rehabilitation with option for subsequent repair showed that 50% of patients who underwent early rehabilitation did not require ACL repair at 2 year follow up!
Surgery for an ACL tear depends on the patient and the degree of the tear. Often, surgery is recommended, but it is not always required even in the case of more extensive ACL tears. Surgery may also help prevent the early developement of knee osteoarthritis.
When performed by trained specialists using your own biologic materials, regenerative procedures are generally considered safe and may support healing processes. These procedures should always be performed with imaging guidance like ultrasound and fluoroscopy to target very specific structures in or around the knee joint.
Recovery times vary by condition and treatment. Rehabilitation and regenerative care may take weeks to months for optimal improvement.
Imaging studies like MRI can be very useful in the diagnosis of an ACL tear and to help determine the best plan of care.
