Arthroscopic Partial Meniscectomy
We are unable to recommend for or against arthroscopic partial meniscectomy in patients with osteoarthritis of the knee with a torn meniscus.

Currently, arthroscopic partial meniscectomy is routinely performed in patients with symptomatic osteoarthritis of the knee who also have primary signs and symptoms of a torn meniscus.

Herrlin et al.127 compared arthroscopic partial meniscectomy followed by supervised exercise to supervised exercise alone and measured KOOS pain, symptoms, activities of daily life, sports/recreation, and quality of life subscales scores as outcomes. The study was downgraded from moderate- to low- strength because 40% of patients declined participation and the arthroscopic group had non-homogeneous preoperative KOOS scores. The authors reported no significant treatment benefits of meniscectomy using any of the outcomes at eight weeks and six months. Since there was only one low-strength study, the recommendation was graded inconclusive.
