What is ACL Tear?
The anterior cruciate ligament, or ACL, is a band of tissue in the center of the knee that keeps the shin bone from sliding forward and rotating.
It is one of the main stabilizers of the joint.
Most ACL tears happen during a sudden stop, pivot, or landing, often in sports. Many people feel a pop, followed by swelling within hours and a feeling that the knee is unstable.
A torn ACL does not grow back together. Whether it needs surgery depends on how unstable the knee feels and what activities you want to return to.
How is ACL Tear diagnosed, and what does the visit involve?
Dr. Robinson tests the knee's stability with maneuvers such as the Lachman test, which checks how far the shin bone shifts forward.
X-rays rule out fracture. An MRI scan, which shows ligaments and cartilage, confirms the tear and checks for related meniscus or cartilage injury.

What is recovery like for ACL Tear?
Not every ACL tear needs surgery.
People with lower activity demands and a stable knee may do well with therapy alone. Those who pivot, cut, or play contact sports often choose reconstruction. Dr. Robinson will weigh your stability, your goals, and any other knee injuries before recommending a path.
