The aim: to study the results of surgical treatment of patients with injuries of the meniscus of the knee joint, in whom arthroscopic suturing of the meniscus was used according to the developed technique.Methods. In this paper, we studied the results of surgical treatment of 134 patients with chronic injuries of the meniscus of the knee joint, who were treated at the City Clinical Hospital No. 7 in Almaty for the period from 2017 to 2021. 70 (52.3%) patients made up the control group, who underwent meniscus resection using arthroscopic technique. The main group included 64 (47.7%) patients with ruptures of the meniscus of the knee joint. He performed a meniscus suture under arthroscopic control according to the method developed by us (RK patent No. 35413 dated 12/10/2021). Results. Clinical application of a new method of arthroscopic meniscus suturing in patients of the main group allowed to increase the frequency of excellent results by 7.3% (p=0.012), good treatment results by 19.7% (p<0.001) according to the Lysholm scale compared with the control group. The treatment outcomes of patients in the study groups, analyzed using the criteria of evidence-based medicine, indicate the effectiveness of a new method of arthroscopic meniscus suturing, which reduces the frequency of unsatisfactory outcomes in the long-term period of surgical treatment by 5.5% (p=0.184) compared with the control group.Сonclusions.The results of the research work support the arthroscopic repair of meniscal tears with good long-term results and a low risk of complications. Thus, a new method of arthroscopic suturing of the meniscus provides prevention of the development of contractures, gonarthrosis in the postoperative period in patients with injuries of the meniscus of the knee joint and allows for early functional treatment compared to traditional arthroscopic meniscectomy.Keywords: knee joint, menisci, meniscus injury, osteoarthritis, arthroscopy, meniscus suture, meniscus resection.
