Does ACL reconstruction treat an ACL tear?

During reconstruction, the surgeon removes or clears the damaged ligament tissue and places a tendon graft in its position. The graft is secured inside the thighbone and shinbone so it can gradually become a functional ligament. This is different from simply stitching every torn ACL, because the original ligament may not heal reliably in its usual location.

Surgery is not automatically needed for every ACL tear. The decision depends on knee instability, activity goals, associated meniscus or cartilage damage, examination findings, and response to rehabilitation. Physiotherapy can improve strength, movement, balance, and confidence before or instead of an operation for some people.

Arrange an assessment with an orthopaedic clinician or physiotherapist if a knee injury caused a pop, swelling, restricted movement, or repeated buckling. The assessment may include stability tests and imaging. Until reviewed, avoid twisting, pivoting, and activities that make the knee give way; use the support and exercises recommended for your injury.

If reconstruction is advised, pre-operative rehabilitation often aims to settle swelling and restore comfortable straightening and bending. After surgery, rehabilitation protects the graft while progressively rebuilding leg strength, coordination, and sport-specific control.

Seek urgent care after a knee injury if the foot becomes cold, pale, numb, or weak, if the knee looks deformed, or if severe pain prevents safe movement. Prompt clinical review is also sensible when swelling rapidly develops, the knee repeatedly collapses, or the joint locks and cannot straighten.

Ask whether your tear is partial or complete, whether another structure is injured, what rehabilitation alone might achieve, and how your work or sport affects the decision. Ask what graft options mean for you, how long each recovery stage may take, and which symptoms should prompt an earlier review.
