X-ray Measurement On Adult Knee Joint From Patients With KBD During Treatment

Objective:The morphologic parameters of the patella and patellofemoral joint from patients with Kaschin Beck disease(KBD)were observed and measured using X-ray to search the pattern of radiographic changes of KBD, and to provide data for the clinical diagnosis and treatment, and for the joint replacement.Methods:Eighty-four inpatients with KBD were taken X-ray pictures and comprehensive treatment( such as hot wax, massage therapy, acupuncture with electric stimulation,traditional Chinese medicine and kinetotherapy). The knee joint K-L grading, patella, patellar bone type shift rate, Insall index, sulcus angle, congruence angle, lateral patellofemoral angle, patellofemoral indices were measured on the pictures, and the clinical data about age, gender, clinical manifestations, clinical curative effect from inpatients with KBD were collected, and the correlation between clinical data and the morphologic parameters were analysed statistically.Results:Preliminary results indicate that the patients with KBD in higher level of K-L classification showed more severe the clinical symptoms, and got less the curative effect; the patients with greater congruence angle and the patellofemoral indices, revealed more severe clinical manifestations and gained less clinical effect; the patients with smaller Insall index and lateral patellofemoral angle demonstrated more severe the clinical symptoms and obtained less curative effect. The patients with higher grades in classification of K-L and the patellar, and with greater patellofemoral exponent received higher WOMAC score, i.g more easier left worse sequelae with them after treatment.Conclusion:The knee joint K-L grading, patellar type, Insall index, congruence angle, lateral patellofemoral angle, patellofemoral indices can be used as referent data for judging the clinical curative effect and prognosis of KBD.
