Risks of Knee Arthroscopy

Reviewed by Greg Jaroszynski MD, FRCSC | Last updated May 2026

Knee arthroscopy is commonly performed as a day surgery procedure, but every operation has risks. The risk profile depends on the patient, the condition being treated, and whether additional procedures are performed.

Possible risks

Patients with established osteoarthritis may continue to have symptoms after arthroscopy because the arthritic joint surface, rather than the meniscus alone, may be the main pain generator.
