ACL Tear

The anterior cruciate ligament (ACL) is one of the four major ligaments that stabilize your knee. It controls rotation and keeps your shin bone from sliding forward — the stability you rely on every time you cut, pivot, land, or decelerate.

When the ACL tears, the knee often gives way during twisting or side-to-side movement. Some people can return to straight-line activity without surgery, but athletes and active adults who want to return to pivoting sports usually benefit from reconstruction, followed by a structured return-to-play program.

Diagnosis starts with your story — how the injury happened tells us a lot — followed by a focused physical exam that tests the ligament directly, including Lachman and pivot-shift testing.

MRI confirms the tear and, just as importantly, maps the rest of the joint: the menisci, cartilage surfaces, and other ligaments are injured alongside the ACL in a significant share of cases, and the full picture shapes the surgical plan.

Recovery is a program, not a waiting period. Early weeks focus on swelling control, extension, and reactivating the quadriceps. From there, progressive strengthening builds toward running, then agility, then sport-specific work.

Return to pivoting sports is criteria-based rather than calendar-based — most athletes are cleared somewhere in the 9-to-12-month range once strength, landing mechanics, and confidence testing all pass. Rushing the calendar is the most preventable cause of re-injury.
