Should a torn meniscus be repaired or partly removed?

AI-generated illustration. This is not a real patient or a diagnostic image.

The meniscus helps distribute load over a wider area in the knee. Finding a tear therefore does not mean that all the tissue should be removed. In suitable patients, the aim is to preserve as much healthy, functional meniscus as possible.

Can every tear be repaired?

The location and pattern of the tear, tissue quality and how long it has been present all matter. Repair may have a better chance in areas with a better blood supply. Root tears and certain other tear patterns need specific consideration. Age alone does not determine the entire decision.

Loading and movement restrictions may be needed to protect tissue after repair. Early recovery may differ after partial removal, but an easier short-term recovery does not necessarily mean a better long-term result for every patient.

Is surgery essential?

No. Particularly with degenerative findings, nonsurgical treatment may be appropriate depending on symptoms and examination. When necessary, limited removal of an irreparable, symptomatic fragment may be considered. Meniscal loss changes load distribution; preserving the outer portion does not eliminate osteoarthritis risk. Options and rehabilitation should be discussed together.
