Short-term (3-6 months) results of using a new type of implants for the delivery of intraosseous contents into the cavity of the affected knee joints are presented, i.e. for performing arthro-medullary bypass grafting (AMS). Arthroscopic debridement of the knee joint was performed in 69 patients with stage 2-3 osteoarthritis, whose clinical and demographic data did not differ from each other. Radiographically, the stability of the implant was established for 6 months, without signs of osteolysis and bone loss around the perimeter of the implant. By 6 months, patients after AMS had practically stopped taking drugs, while in the control group at this time, 50% of patients had to regularly take these drugs in one form or another.
