Background. Knee osteoarthritis is a progressive incurable disease that in severe cases leads to total joint replacement, which requires significant economic costs and medical and social adaptation, has a number of postoperative complications and adverse outcomes. Therefore, special attention has recently been paid to the prevention and treatment of the early stages of the disease. The purpose of the study was to conduct a systematic analysis of scientific literature on the prospects and possibilities of using arthroscopy in the early diagnosis of monoarthrosis. Material and methods. A literature search was conducted in the PubMed and MEDLINE databases for 2010–2024 using the following medical subject headings and keywords: “deforming osteoarthritis of the knee joint”, “osteoarthritis of the knee joint”, “unilateral deforming osteoarthritis of the knee joint”, “unilateral osteoarthritis of the knee joint”, “gonarthrosis”, “monoarthrosis”, “arthroscopy”, “diagnosis”, “treatment”. If necessary, literature sources beyond the search period were used in some cases. A general search revealed 48 references on the use of arthroscopy as a diagnostic and therapeutic method in the early stages of monoarthrosis. The primary exclusion concerned the literature in which arthroscopy was used for the diagnosis and treatment of late-stage knee osteoarthritis (n = 38). The secondary exclusion included literature sources that contained only background information (summary, figures, references) (n = 12). As a result, only relevant full-text articles in professional journals remained (n = 15). Results. The lack of correlation between clinical symptoms and radiological signs of knee osteoarthritis causes low availability of orthopaedic care: more than 30 % of newly diagnosed patients have a severe stage of the disease, and in some cases the pathology is detected only in connection with the manifestation of complications; the diagnosis of osteoarthritis due to a large percentage of painless development of the disease (40 %) is often established at terminal stages. All of this suggests the need for further research into the various factors that influence the frequency, prevalence, economic and social burden of knee osteoarthritis. Arthroscopy is potentially the gold standard for validating non-invasive assessment methods such as magnetic resonance imaging, as it provides high magnification and direct view of articular cartilage with non-destructive interactive assessment of its structure and functional properties. Arthroscopy allows for a more detailed description of the depth and extent of lesions, as well as the detection of subtle changes such as cartilage softening, fibrillations, and tangential peeling. Clinical symptoms and structural changes in the knee joint elements visualised during arthroscopy in patients with monoarthrosis are covered in a few studies, some of which were published 10 years ago. The results of modern arthroscopic studies can be an important contribution to the development of diagnostic and differential diagnostic criteria for the early stages of monoarthrosis. Conclusions. Based on information and analytical studies of modern scientific literature, it has been found that knee osteoarthritis is accompanied by persistent pain, significant limitation of the lower limb function, and reduced ability to work, which often leads to joint replacement. Diagnosis of osteoarthritis in the early stages is difficult due to the absence of pathognomonic clinical, radiological and laboratory parameters, and in case of monoarthrosis with synovitis, it is complicated by differentiation with specific arthritis of the knee joint. Arthroscopy allows performing the necessary scope of diagnostic and therapeutic measures with verification of the pathological process and determination of gonarthrosis stage.
