What Is the ACL and Why Is It Important?

The Anterior Cruciate Ligament (ACL) is a vital ligament in your knee that connects the thigh bone (femur) to the shin bone (tibia). It plays a crucial role in:

• Stabilizing the knee during movement

• Supporting activities like pivoting, jumping, and sudden directional changes

An ACL injury can lead to knee instability and hinder daily activities. In certain cases, instead of replacing the torn ligament, surgeons can repair it, preserving the natural tissue.

How Is the Procedure Done?

ACL repair involves reattaching the torn ends of the ligament using specialized surgical techniques. This approach is typically considered when:

• The tear is located near the ligament's attachment to the bone (proximal tear).

• The tissue quality is good.

The procedure is performed arthroscopically, using small incisions and specialized instruments to access and repair the ligament.

Latest Techniques and Technologies

Modern advancements have enhanced the effectiveness of ACL repair:

• InternalBrace™ Technique: This method uses a high-strength FiberTape® suture to reinforce the repaired ligament, providing additional support during healing. Learn more about this technique in the ACL Primary Repair Using the InternalBrace™ Technique video.

• SwiveLock® ACL Repair Kit: A comprehensive system designed to facilitate ACL repair procedures, ensuring precise and secure fixation. Details can be found in the ACL Preservation With the SwiveLock® ACL Repair Kitanimation.

• ACL Repair TightRope® Implant and FiberRing™ Sutures: These tools allow for tensionable fixation and simplified suture management during repair. Explore this technique in the ACL Primary Repair Using the ACL Repair TightRope® Implant and FiberRing™ Sutures video.

These innovations aim to restore knee stability while preserving the natural anatomy of the ligament.

Is ACL Repair Right for You?

Not all ACL injuries are suitable for repair. Factors that may influence the decision include:

• Location of the Tear: Proximal tears (near the bone attachment) are more amenable to repair.

• Tissue Quality: Good-quality ligament tissue increases the likelihood of a successful repair.

• Time Since Injury: Early intervention may improve outcomes.

Your orthopedic surgeon will assess these factors to determine the most appropriate treatment for your specific condition.

Recovery and Rehabilitation

Recovery timelines can vary, but generally, patients can expect:

• Initial Healing Phase: Focus on reducing swelling and restoring range of motion.

• Strengthening Phase: Gradual introduction of exercises to rebuild strength.

• Return to Activity: Depending on progress, return to sports or high-impact activities may be possible within several months.

Adherence to a structured rehabilitation program is essential for optimal recovery.

Famous Athletes Who Returned After ACL Repair

While ACL reconstruction is more common in elite sports, interest in ACL repair is growing with advancements in technique. Several athletes are now returning to play after undergoing ACL repair:

Cooper Kupp (NFL)

• Injury: Suffered a torn ACL in 2018.

• Procedure: Reports suggest a hybrid repair technique.

• Comeback: Returned to become Super Bowl MVP in 2022.

Kelley O’Hara (USWNT)

• Injury: Sustained an ACL tear early in her career.

• Comeback: Continued a highly successful international career, winning World Cup titles and competing in multiple Olympics.
