Eligibility
Inclusion criteria
Inclusion criteria: -Subjects who are undergoing total knee arthroplasty for one or both knees due to primary knee degenerative arthritis between 55 and 85 years of age. Year) -Kellgre-Lawrence grade (0-4, 5 stage) grade 0: no radiographic features of osteoarthritis grade 1: Radiological findings suggest that the joint gap is slightly narrowed and bone projections are suspected Grade 2: The radiological findings show a narrow joint gap and clearly visible bone protrusions. Grade 3: Radiological findings show that the joint gap is narrow, several bone protrusions are visible, bone deformity is visible, and bone sclerosis is visible. Grade 4: Radiological findings show that the joint gap is clearly narrowed, large bone protrusions are observed, severe bone sclerosis and clear bone deformity are observed. -Subjects who have fully explained the preoperative study and expressed their intention to participate
Exclusion criteria
Exclusion criteria: -Subjects diagnosed with inflammatory arthritis (rheumatic arthritis, psoriatic arthritis, spondylosis, etc.) -Subjects with post-traumatic arthritis in the knee due to surgery -Subjects with arthritis due to bone necrosis in the knee due to surgery -A person with a history of infectious arthritis in the knee joint due to surgery -Subjects with reduced range of motion of the knee joint (more than 20 degrees of flexion construction and less than 90 degrees of subsequent flexion) -Subjects with very severe valgus and varus deformity (Hip-Knee-Ankle angle ± 15 degrees or more) -When the destruction and deformation of the joint is severe, it is expected to perform artificial joints using bone grafts, blocks, and long poles. -Subjects who are deemed to have an impact on the analysis of results due to severe deformation of the femur, tibia and patella including around the knee joint -If it is judged that it is not appropriate to be included in the study by other responsible researchers
