Abstract: BACKGROUND: Patellofemoral pain syndrome is a common disease in the field of sports injuries. Research in and outside China is increasing year by year, but there is no visual analysis for patellofemoral pain syndrome. OBJECTIVE: To objectively analyze the literature research on patellofemoral pain syndrome in and outside China in the past 13 years, to summarize the recent research directions in this field and to sort out the knowledge structure in and outside China. METHODS: Relevant articles on patellofemoral pain syndrome were collected from Web of Science and CNKI. Citespace software was used for visual analysis to show the research hotspots and development trends of this field. RESULTS AND CONCLUSION: (1) A total of 1 679 articles were finally included in the Web of Science database. The authors with the most articles are De Oliveira Silva D from La Trobe University in Melbourne, Australia and Crossley KM from the University of Melbourne, Australia. Hot keywords are hip, biomechanics, prevention (prognosis), prevalence disease rate, consensus statement, gender differences, electromyographic activity, risk factor, and osteoarthritis. (2) A total of 214 articles were included and analyzed in the CNKI database. The author with the most articles is Miao Ping from the Rehabilitation Department of the Second Affiliated Hospital of Guangzhou Medical University. Hot keywords are arthroscopy, biomechanics, strength training, lateral femoral muscle, surface electromyography, patellofemoral arthritis, and joint replacement. (3) International research hotspots show the biomechanical characteristics of increased knee external rotation, increased hip adduction, and decreased hip internal rotation during patient exercise. Strengthening the hip abductors and external rotators can effectively improve the pain and function of patients. At present, the most appropriate method to treat the disease in the world is a customized multi-modal intervention program, including strengthening of the gluteal muscles and quadriceps, emphasizing education and activity adjustment. (4) The results of major Chinese studies in this field confirm that the use of arthroscopic surgery can improve the pain of patients with patellofemoral pain syndrome, and patellofemoral joint replacement has a certain effect on early severe patellofemoral arthritis in such patients. Rehabilitation training methods are mainly based on hip joint strength training, supplemented by core muscles, lower limb eccentric strength and neuromuscular control training. Compared with foreign countries, the unique research hotspots in China are acupuncture and Chinese medicine.
