One hundred and eight patients with knee pain and a degenerative horizontal tear of the posterior horn of the medial meniscus were randomized to be treated either with arthroscopic meniscectomy or conservative treatment (strength training). The aim of the trial was to evaluate if the surgical procedure provided superior clinical outcomes, measured by Visual Analog Scale (VAS) pain, Lysholm knee score, Tegner activity scale, patient subjective knee pain and satisfaction. After 2 years of evaluation, the treatments did not differ in terms of keen pain relief, knee function, or satisfaction.
