The METEOR trial is a multicenter RCT testing whether arthroscopic partial meniscectomy beats structured physical therapy for degenerative meniscal tears. It enrolled 351 symptomatic patients aged 45 and older with a meniscal tear and mild-to-moderate knee osteoarthritis on imaging. The primary outcome was change in WOMAC physical-function score at 6 months.
When a patient 45 or older presents with knee pain, a degenerative meniscal tear, and mild-to-moderate OA on imaging, start with structured physical therapy rather than rushing to arthroscopy. The key teaching point: a meniscal tear on MRI is not automatically the pain generator. Two-thirds of tears in this age group are incidental, so the arthritis is often the real driver of symptoms.
This explains the result. Trimming the meniscus does not treat the underlying osteoarthritis, while PT improves strength and function regardless of the tear. This is the first large multicenter RCT on this question, and per the editorial team it shifted degenerative meniscal tear management worldwide toward an initial nonoperative trial.
For critical appraisal, know the limitations: only 26% of eligible patients enrolled (selection bias), the trial was unblinded, and the 30% crossover complicates interpretation. The intention-to-treat analysis is the trustworthy result; the "success rate" secondary outcome favoring surgery is biased.
