An ACL tear is one of the most common and frustrating knee injuries, especially for athletes and active individuals.
Traditional treatment often involves surgery followed by a long, difficult recovery.
But what if there was another option?
Platelet-Rich Plasma (PRP) therapy is an innovative, non-surgical treatment that may help ACL injuries heal faster and more effectively.
If you’re looking for a way to avoid surgery and get back to your active lifestyle, PRP could be the answer.
In this guide, we’ll break down what PRP is, how it works for ACL tears, and why it might be the right choice for you.
SEE HOW PRP CAN HELP YOUR ACL TEAR
What is an ACL Tear?
The anterior cruciate ligament (ACL) is one of the key stabilizers of the knee.
It helps control movement and keeps the knee from shifting too much.
An ACL tear is when this ligament gets a partial or full tear, causing the knee to become unstable.
Common Causes of ACL Tears
- Sudden stops or direction changes (common in sports like soccer and basketball)
- Direct impact or trauma to the knee
- Landing awkwardly from a jump
Symptoms of an ACL Tear
- A popping sound or sensation at the time of injury
- Rapid swelling within hours
- Knee instability or a feeling of “giving out”
- Limited range of motion and pain when bending the knee
Traditional Treatment Options for ACL Tears
Let’s look at some of the traditional treatments for ACL tears:
Conservative Treatment
- Rest, Ice, Compression, and Elevation (RICE method)
- Physical therapy to strengthen surrounding muscles
- Knee bracing to provide extra support
ACL Reconstruction Surgery
- Replaces the torn ligament with a graft (from hamstring, patellar, or cadaver tissue)
- Requires 6 to 12 months of rehabilitation
- Potential risks include graft failure, stiffness, and arthritis later in life
While surgery is often recommended, it’s not always necessary—especially for partial ACL tears.
That’s where PRP therapy comes in.
How PRP Therapy Can Help with ACL Tears
PRP therapy uses a concentrated form of platelets from your own blood to promote healing.
Platelets contain powerful growth factors that help repair damaged tissue and speed up recovery.
How PRP Works for ACL Injuries
- Stimulates natural healing by boosting collagen production
- Reduces inflammation and pain
- Strengthens the ligament as it repairs itself
What the Research Says About PRP For ACL Tears
Studies show that PRP injections can help ACL injuries heal faster, particularly for partial tears.
Some research even suggests that PRP can be effective for patients recovering from ACL surgery by accelerating healing and reducing post-surgical pain.
PRP vs. Surgery for ACL Tears
| Treatment | PRP Therapy | ACL Surgery |
| Invasiveness | Non-surgical injection | Invasive surgery |
| Recovery Time | 4-12 weeks | 6-12 months |
| Best for | Partial ACL tears, moderate injuries | Full ACL ruptures |
| Success Rate | High for partial tears | High for full reconstructions |
| Risks | Minimal (mild soreness) | Graft failure, stiffness, long rehab |
When is PRP a Better Option?
- If you have a partial ACL tear and want to avoid surgery
- If you need to recover quickly for sports or work
- If you’ve tried rest and physical therapy without success

FAQs: PRP For ACL Tear
How long does an ACL tear take to heal without surgery?
The healing time for an ACL tear without surgery depends on the severity of the injury. A partial ACL tear may take 3 to 6 months to heal with rest, physical therapy, and regenerative treatments like PRP. A complete tear, if not surgically repaired, may not fully heal on its own but can sometimes be managed with rehabilitation and bracing.
Does PRP work on a torn ACL?
Yes, PRP therapy can be effective for partial ACL tears, helping to reduce inflammation, stimulate tissue repair, and speed up recovery. Studies suggest that PRP may also aid in post-surgical healing after ACL reconstruction by accelerating tissue regeneration and reducing pain. However, for fully ruptured ACLs, PRP alone is unlikely to restore full ligament function without surgery.
What is the fastest way to recover from an ACL tear?
The fastest way to recover from an ACL tear is a combination of regenerative medicine, physical therapy, and lifestyle modifications. PRP therapy can accelerate healing by stimulating tissue repair, while structured physical therapy helps restore strength and mobility. Proper nutrition, hydration, and avoiding activities that strain the knee can also support a quicker recovery.
Can I walk after a PRP injection in my knee?
Yes, most patients can walk immediately after a PRP injection. However, it’s common to experience mild soreness or stiffness for a day or two. While normal walking is generally fine, high-impact activities like running or jumping should be avoided for a few days to allow the PRP to begin working effectively. Your doctor will provide specific guidance based on your injury.
Is walking bad for an ACL tear?
Walking is generally not harmful for a mild or partial ACL tear, as long as there is no significant pain or instability. In fact, early mobility exercises can aid in recovery. However, excessive walking or weight-bearing on a fully torn ACL may worsen symptoms or lead to further knee damage. If you have an ACL tear, it’s important to follow a structured rehabilitation plan.
Why no caffeine after PRP?
Caffeine is often discouraged after PRP therapy because it can act as a vasoconstrictor, meaning it narrows blood vessels and reduces circulation. Since PRP relies on blood flow to deliver healing growth factors, avoiding caffeine for a short period—usually 24 to 48 hours—can help maximize the effectiveness of the treatment. Hydration and proper nutrition also play a crucial role in recovery.
