Needle Lavage

This article is part of a series of blog posts regarding the American Academy of Orthopedic Surgeons’ (AAOS) Full Treatment Guideline For Knee Osteoarthritis.

Recommendation 17 – The AAOS does not recommend needle lavage for patients with symptomatic knee OA.

Needle lavage involves rinsing out the knee joint with saline solution.  4 studies were examined surrounding this treatment option.  In only one of those studies were there statistically significant results showing that needle lavage was effective.  The remaining science said there was little to no effect on needle lavage in relation to pain, swelling, and knee function.
