ACL Reconstruction Surgery FAQ
What Is ACL Reconstruction?
ACL reconstruction is surgery to replace a torn anterior cruciate ligament (ACL) in the knee. The ACL stabilizes the knee during pivoting and sudden direction changes. Surgery is commonly recommended for active individuals or those with knee instability after a complete tear.
Why Might ACL Reconstruction Be Needed?
Common reasons for surgery include:
- Knee instability with sports or daily activities
- A complete ACL rupture confirmed by imaging or exam
- Associated injuries such as meniscus tears
- Failure of non-surgical treatment to restore stability
What Are the Symptoms of an ACL Tear?
Symptoms can include:
- A popping sensation at the time of injury
- Immediate swelling in the knee
- Instability or the knee “giving way”
- Pain with pivoting or sudden stops
- Reduced range of motion
About the ACL Reconstruction Procedure
ACL reconstruction is usually performed arthroscopically under general anesthesia and takes one to two hours. The surgeon removes the damaged ACL and replaces it with a graft, often taken from the patient’s own hamstring or patellar tendon, or from a donor. The graft is secured with surgical hardware and allowed to heal into place.
What Happens After Surgery?
Patients typically go home the same day with a brace and crutches. Swelling control, early motion, and guided physical therapy begin shortly after surgery. A structured rehabilitation program is essential for restoring strength and stability.
How Long Does Recovery Take?
Recovery varies, but common milestones include:
- Walking without crutches within a few weeks
- Jogging around three to four months
- Return to pivoting sports in six to twelve months
Following rehab guidelines closely helps reduce the risk of re-injury.
What Are the Potential Complications?
Possible complications include:
- Infection or bleeding
- Stiffness or loss of motion
- Graft failure or re-tear
- Blood clots
- Persistent pain or weakness
Your surgeon will discuss how to minimize these risks.
Can I Return to Sports?
Most athletes can return to sports after completing rehabilitation and passing strength and stability testing. A gradual return plan reduces the chance of re-injury.
When Should I Seek Medical Attention?
Seek medical care if you develop fever, severe swelling, calf pain, or sudden knee instability after surgery.
