Tearing your ACL is scary — but with modern arthroscopic reconstruction and a structured rehab program, the vast majority of athletes return to the sports they love. Here's what to know.
Most patients know something is seriously wrong the moment it happens. The combination of a "pop," rapid swelling, and an unstable knee is a high-probability ACL story until proven otherwise.
Diagnosis starts in the office with a careful history and a few specific exam tests — the Lachman, anterior drawer, and pivot shift. We confirm with an MRI, which also identifies any associated injuries to the meniscus, cartilage, or other ligaments. Most ACL tears come with at least one companion injury, and identifying them up front shapes the surgical plan.
The anterior cruciate ligament (ACL) is one of the four main ligaments stabilizing your knee. It runs from the back of your femur to the front of your tibia and is the primary restraint to forward and rotational motion. Without an intact ACL, the knee can buckle during cutting, pivoting, or landing.
Most ACL tears happen without contact — a planted foot with rotational force, an awkward landing where the knee collapses inward, or a backward fall on skis. Cutting and pivoting sports (soccer, basketball, football, lacrosse, skiing) account for the majority of injuries we see. Direct-contact tears from a blow to the side of the knee are less common but real.
Female athletes have a 2–8x higher incidence than males in comparable sports. ACL tears can also happen to weekend warriors and patients well into their 50s and 60s.
Not every ACL tear requires surgery. The right path depends on your age, activity level, the demands you place on your knee, and whether other structures are also injured. We make this decision together.
Best for low-demand patients who don't play cutting or pivoting sports and whose knees feel stable for daily life.
A chronically unstable ACL-deficient knee carries a higher risk of meniscus tears and accelerated cartilage damage.
Recommended for active patients, athletes, and anyone whose knee feels unstable in the activities they want to return to.

ACL recovery is a structured, phased process. Skipping ahead is the #1 cause of re-injury — patience in the early phases pays off in the late ones.
Brace, crutches, ice, elevation. Quad activation begins immediately.
Off crutches by week 4 in most cases. Stationary bike, closed-chain strengthening.
Single-leg work, balance, controlled plyometric progression. The quad is the make-or-break muscle — we measure it.
Jumping and landing mechanics. Sport-specific drills. Strength testing to track quad symmetry.
Single-leg hop battery and isokinetic strength testing. Cleared for full practice, then full game play in a brace.
Not always. If you don't play cutting or pivoting sports and your knee feels stable, structured rehab may be enough. If you want to return to soccer, basketball, football, lacrosse, skiing, or anything else that involves cutting and pivoting, reconstruction is almost always the right call.
For right-knee surgery, typically 4–6 weeks — once you're off narcotic pain medication and out of the brace for daily activities. For left-knee surgery in an automatic, often within 2 weeks.
There's no single "best" graft — there's a best graft for you. Bone-patellar tendon-bone is a historical gold standard for high-demand athletes. Quadriceps tendon is excellent for revisions and certain anatomies. Hamstring is reliable and lower-morbidity. Allograft (donor) is reserved for select older patients. We discuss the trade-offs in detail before surgery.
Yes, but it's uncommon when reconstruction and rehab are both done well. Reported re-tear rates range from roughly 5–10%, with the highest risk in young athletes returning to cutting sports. Objective return-to-sport testing and a brace for the first season back minimize that risk.
Most ACL tears come with some meniscus injury. Our default is to repair the meniscus whenever it's repairable — preserving the meniscus protects the knee long-term. Either way, it's done in the same surgery as the ACL.

Most patients with a suspected ACL tear are seen within a few days. The sooner we evaluate it, the sooner we can build a plan.
