Background
How well torn menisci heal in children and teenagers when they are repaired surgically — rather than removed — and which factors affect that healing. We followed 25 young patients (29 menisci) for an average of 2.3 years.
Rationale
The meniscus is the C-shaped shock absorber inside the knee. Removing it — once standard practice — substantially raises the risk of arthritis later in life. In a still-growing knee, that risk is even more important. Meniscal tears are uncommon in children, so the evidence on whether they should be repaired (rather than trimmed) has been thin.
Results
24 of the 29 menisci healed and the patient was symptom-free. The four re-ruptures all happened in the same poorly-supplied middle portion of the meniscus, after a new injury. Patients who had a torn ACL repaired at the same time as the meniscus tended to do better. Activity scores dropped slightly, but most patients returned to good knee function.
Implications
For children and adolescents with an unstable meniscal tear, repair — not removal — should be the default. Most heal. The harder area to fix is the middle portion, where the blood supply is poorer. If there is a coexisting ACL injury, doing both at once may improve the outcome.
