ACL tear: assessment and treatment

The knee depends on its ligaments for stability, because the bones themselves fit together loosely. The ACL is the most frequently torn knee ligament in many athletic populations.

A typical injury is a twisting deceleration as the shin shifts forward; the meniscus or cartilage can be injured at the same time.

Once the initial pain and swelling settle, many patients notice instability — especially when cutting, on uneven ground, or returning to pivoting sport — even if everyday walking feels fine.

Repeated episodes of the knee giving way can raise the long-term risk to the cartilage, which is why every plan is tailored to your age, activity demands, and examination findings.

Non-operative care focuses on strengthening and neuromuscular control; some patients adapt well, while others — often younger pivoting athletes — proceed to ACL reconstruction when instability persists.

Reconstruction uses a graft (commonly hamstrings, patellar or quadriceps tendon, or a donor allograft) placed through bone tunnels to restore forward stability.

Rehabilitation takes time; returning to high-demand pivoting sport usually requires many months of structured, progressive training.
