Habitual Patellar Dislocation

Brief summary

Adult habitual dislocation of the patella is a common dislocation of the patella. The range of lesions is wide and the severity is high. Clinical diagnosis and treatment are difficult. In clinical work, misdiagnosis and treatment are not targeted at pathological mechanisms. This leads to irregular diagnosis and treatment, high failure rate and revision rate, and patients undergoing multiple operations. The project team developed a four-in-one surgical technique centered on tibial tuberosity osteotomy and proximal displacement in the preliminary research, which overcomes the disadvantages of traditional knee extension surgery and is suitable for adults. Early research Shows safe and effective clinical efficacy. The purpose of this application project is to take independent innovation of core surgical technology as the lead, adopt a two-way cohort study method, compare the clinical efficacy of the new four-in-one technology and traditional soft tissue surgery in the treatment of adult habitual patellar dislocation, and analyze and formulate adult habituation Comprehensive and systematic solutions for patella dislocation, relying on this scientific research project to conduct multi-center and large-sample clinical case studies, and evaluate the effectiveness and safety of independent innovative technologies through standardized medical research methods to improve the surgical treatment of adult habitual patella dislocation Success rate, reduce recurrence rate and failure rate, improve the level of clinical treatment of the disease, and finally put forward a special clinical diagnosis and treatment system for the disease in the international academic community.
