Brief summary
The goal of this clinical study is to evaluate the effectiveness of the properties that support the functional state of the joints and the safety of the dietary supplement for food ARTNEO®, oral capsules, in patients with stage II-III primary osteoarthritis of the knee joint. The main questions it aims to answer are: 1. To evaluate the effectiveness of the joint functional state-supporting properties of dietary supplement ARTNEO®, capsules for oral administration, in patients with stage II-III primary osteoarthritis of the knee joint; 2. To evaluate the safety of dietary supplement ARTNEO®, capsules for oral administration, in patients with stage II-III primary osteoarthritis of the knee joint. Participants will be randomly distributed equally among two groups: * Group 1 ARTNEO (106 people): patients take the study dietary supplement ARTNEO®, 1 capsule 1 time per day for 6 months; * Group 2 Placebo (106 people): patients take placebo 1 capsule 1 time per day for 6 months.
