ACL Reconstruction Surgery Guide

What Is ACL Reconstruction?

ACL reconstruction is a surgical procedure to replace a torn anterior cruciate ligament (ACL) — one of the four major ligaments that stabilizes the knee. The ACL connects the femur to the tibia and prevents the shin from sliding forward. When torn, the knee becomes unstable, especially during cutting, pivoting, and deceleration movements. Over 200,000 ACL injuries occur annually in the US, with about half requiring surgical reconstruction.

Who Needs ACL Surgery?

Not all ACL tears require surgery. Surgery is typically recommended for:
• Athletes who want to return to cutting/pivoting sports (soccer, basketball, football, skiing)
• Active individuals who experience knee instability during daily activities
• Combined injuries (ACL + meniscus tear or other ligament damage)
• Young patients with years of active life ahead

Non-surgical treatment may work for:
• Partial ACL tears with good stability
• Sedentary or low-demand patients
• Older patients willing to modify activities

ACL Surgery Cost

ACL reconstruction costs $12,000 to $50,000 before insurance. Most insurance plans cover ACL surgery when medically necessary (confirmed by MRI + physical exam). Out-of-pocket costs with insurance are typically $2,000-$6,000.
