A nomogram predictive model for aseptic loosening after tumor prosthetic replacement around the knee joint. The corresponding points for each factor are based on the condition of the patient, which can be determined by making a vertical line upwards (e.g., a patient with prosthetic stem length < 14 cm will receive between 70 and 80 points). Add all the points to get the total score, then find the corresponding points on the total points axis and make a vertical line down to predict the 5-year and 10-year survival rate without aseptic loosening
