Partial ACL Tear Symptoms: Do You Need Surgery

Have you ever felt sudden knee pain while playing sports or running? Or maybe you heard a “pop” sound and now your knee feels weak or wobbly? You could be dealing with a ligament injury. One common condition is a partial ACL tear. While it is not a complete tear, it can still seriously affect your daily activities and sports performance.

In this guide, we explain common partial ACL tear symptoms, how the injury is diagnosed, and the best treatment options. All insights are based on the expert experience of Dr. Manu Bora, who has helped thousands of patients recover safely and quickly.

What Does a Partial ACL Tear Feel Like?

The Anterior Cruciate Ligament (ACL) works like a strong rope inside your knee, keeping the joint stable. When this ligament is overstretched or partially damaged, it results in a partial tear.

Common partial ACL tear symptoms include:

• Pain on the inside or outside of the knee: Discomfort may be deep within the joint or along the sides.
• Swelling: The knee may become puffy within a few hours after injury.
• Instability: A sensation of the knee “giving way,” especially during turning or pivoting.
• Loss of motion: Difficulty fully bending or straightening the leg.

Ignoring these signs can be risky. A partial ACL tear can worsen into a complete tear if not treated properly.

How to Diagnose a Partial ACL Tear

Recognizing symptoms is the first step, but an accurate diagnosis requires expert evaluation. Dr. Manu Bora explains that physical examination tests can indicate ACL damage, but imaging is essential for confirmation.

An MRI scan is the most reliable test. It shows how much of the ligament is torn—whether the damage is minor or more extensive. This information directly influences treatment decisions. In some cases, X-rays are also used to rule out fractures.

Can a Partial ACL Tear Heal Without Surgery?

This is the most common concern among patients. The good news is that many partial ACL tears can heal without surgery.

Dr. Manu Bora advises that if the tear is low-grade and the knee remains stable, non-surgical treatment may be sufficient. Options include:

• PRP Therapy: Platelet-Rich Plasma injections help stimulate natural ligament healing.
• Rehabilitation: Structured physiotherapy strengthens the muscles around the knee and improves stability.

However, if the tear is high-grade or if you plan to return to demanding sports like football or cricket, additional support may be necessary.

Advanced Treatment: The Internal Brace

When surgery is required, Dr. Manu Bora uses an advanced technique called the Internal Brace.

Unlike traditional ACL surgeries that rely heavily on screws, the Internal Brace uses a strong fiber tape that acts like a seatbelt for the healing ligament, providing extra protection during recovery.

Why the Internal Brace Is Better

• No painful screws: Uses bio-absorbable and soft fixation materials.
• Faster recovery: Many patients walk without crutches the very next day.
• Earlier return to sports: Athletes often return within 3–4 months instead of the traditional 9 months.

This technique is also highly effective for ACL tear injuries in children, as it is safe and growth-friendly.

Other Knee Injuries to Watch For

ACL injuries often occur along with damage to other knee structures. Dr. Manu Bora carefully evaluates the entire knee to ensure complete recovery.

• Meniscus Tear: Damage to the knee’s cushioning cartilage.
• MCL or LCL Injuries: Side ligaments of the knee may also be affected.
• Multiple Ligament Injuries: In some cases, the PCL (posterior ligament) is involved.

Treating only one ligament without addressing associated injuries can lead to poor outcomes, which is why a comprehensive approach is essential.

Conclusion: Don’t Ignore Knee Pain

A partial ACL tear is a serious condition, but it is highly treatable. Whether your recovery involves rehabilitation, PRP therapy, or advanced Internal Brace surgery, early action is critical.

Delaying treatment can increase the risk of arthritis and further knee damage. Dr. Manu Bora has helped athletes and non-athletes alike return to pain-free, active lives.

Frequently Asked Questions (FAQs)

1. What are the main partial ACL tear symptoms?

Common symptoms include knee pain, swelling, and a feeling of instability or wobbling, especially during turning movements.

2. Can a partial ACL tear heal without surgery?

Yes. Many low-grade partial tears heal with rehabilitation and treatments like PRP. Surgery is considered if the knee remains unstable.

3. What is Internal Brace surgery?

It is an advanced surgical technique using fiber tape to protect and support the healing ligament, allowing faster recovery.

4. How long does recovery take for a partial ACL tear?

Non-surgical recovery usually takes 6–12 weeks. With Internal Brace surgery, patients may return to sports in 3–4 months.

5. Is an MRI necessary for a partial ACL tear?

Yes. An MRI helps determine the extent of the tear and checks for associated injuries such as meniscus or cartilage damage.
