To Investigate The Correlation Between Peripatellar Pain Of Patients With Early KOA And Patellofemoral Joint Structure Disorder

ObjectiveHealthy people and KOA patients by measuring parameters of knee joint (patellofemoral in dices, congruence angle, lateral patellofemoral angle and patellar lateral shift ratio), a retrospective study of KOA patients for clinical and imaging features, clinical features and imaging characteristics of summed up the syndrome types, analysis of the correlation between these parameters in patients with KOA peripatellar pain, and discuss its clinical significance of knee osteoarthritis in early diagnosis, treatment.MethodsCollection of KOA patients in outpatient or hospitalization data and imaging examination results, and analyzed the measurement results through the patella X ray on the inclusion criteria of45°axial slices on the patellofemoral in dices, congruence angle, lateral patellofemoral angle and patellar lateral shift ratio and other parameters of the KOA patients, patellofemoral structure relation of imaging and clinical characteristics of retrospective study, summarizing the correlation analysis of early KOA patients peripatellar pain and patellofemoral structure relationship.ResultsThis study collected a total of40KOA patients and20healthy people, a total of60knee joints. The study found that:1the KOA of patients with knee joint in the male11cases, female29cases, accounted for27.5%,72.5%. The proportion of men and women close to:1:3, KOA patients and the health of two groups of gender comparison, using Fisher’s exact test, X2,=11.48, p=0.049, P<0.05, female prevalence was higher than that of men. Health group, mean age37.4±0.99, pain group the average age was44.8±0.46, with independent sample t test method, t=-7.735, P<0.001, two groups had statistical significance in age. Lateral patellar pain patients with a total of21cases, accounting for45%, the upper edge of the patella, medial, lateral and inferior border of gender by chi square test, p=0.639, no statistical significance.2according to the condition of patients and clinical symptoms, according to different TCM syndrome types, divided into three groups, the knee joint parameter measurement results are as follows, using a separate sample comparison, comparing data of different group two, P>0.01, patellofemoral in dices, congruence angle, lateral patellar angle data of the three groups had no significant difference.3according to the condition of patients with clinical symptoms, SF-MPQ pain questionnaire according to the reference standard, different degree of pain were divided into three groups, the knee joint parameter measurement results are as follows, compare the data of different group two, P>0.01, patellofemoral in dices, congruence angle, lateral patellar angle data of the three groups showed no statistical significance.4healthy patients and peripatellar pain in patients with knee KOA parameters (patellofemoral in dices, congruence angle, lateral patellofemoral angle) measurements, peripatellar pain in patients with patellofemoral in dices than healthy patients with patellofemoral in dices generally are relatively large, P<0.05, there was significant difference, that of patellofemoral joint gap asymmetry, patellar lateral tilt there is tendency, subluxation. Peripatellar pain patients health group lateral patellofemoral angle, using a separate sample analysis, P>0.05, no significant difference was found between two groups.5early KOA patients with different pain at the site of patellofemoral in dices, right angle and lateral patellofemoral angle by using the ANOVA analysis, P was greater than0.05, the knee pain of different parameters showed no statistical significance.6due to lateral patellar pain (30-47) group were only1people, not included in the three group of two two, group0-15and group15-30by independent sample analysis, t=1.773, p=0.093, there is no significant difference between the two groups.7a total of40cases, grade I male9cases, female27cases, second degree male1cases, female2cases, male1cases of grade III patients accounted for90%. Conclusion1patients with early KOA peripatellar pain symptoms and gender of patients are closely related, middle-aged women too much. 2. Among the different TCM syndromes, patellofemoral in dices, congruence angle, lateral patellofemoral angle measurements showed no significant difference.3patellofemoral joint structure disorder is caused by an KOA peripatellar pain in patients with early important reason.
