New research, guidelines and FDA decisions, each with a note on what it might change in a conversation with your surgeon, how certain it is, and links to the original sources.

A systematic review of 12 studies with more than five years of follow-up found that repairing a medial meniscus root tear was associated with better outcomes than partial meniscectomy.
What this could change in a conversation with your surgeon: If you have a root tear, ask whether repair is an option. The included studies were mostly lower-quality, so the evidence is still building.
Researchers reviewed 171 patients whose complex meniscus tears were repaired. 13.5% needed more surgery, and previous surgery on the same knee was the only factor linked with failure.
What this could change in a conversation with your surgeon: Tears once routinely trimmed may be repairable. Ask whether repair is possible before agreeing to remove tissue.

The British Association for Surgery of the Knee said the FIDELITY trial tested a specific group, and that selected patients with mechanical symptoms who have completed physiotherapy may still benefit from arthroscopy.
What this could change in a conversation with your surgeon: Experts agree trimming shouldn't be routine for wear-related tears. They still debate whether it helps a smaller group.

The FIDELITY trial randomized 146 adults with degenerative tears to partial meniscectomy or sham surgery. At 10 years, the meniscectomy group did no better. Arthritis progressed in 81% versus 70%, and 12% versus 4% went on to knee replacement or osteotomy.
What this could change in a conversation with your surgeon: This is the strongest long-term evidence yet. If your tear is from wear, ask about structured therapy before surgery.
