Abstract

Abstract:

BACKGROUND: The change of the axial angle of the lower limb is related to the occurrence and development of osteoarthritis.

OBJECTIVE: To analyze the correlation between the change of lower limb power line and pain area in the knee osteoarthritis patients.

METHODS: Totally 65 knee osteoarthritis patients were selected as pain group and 30 healthy people were selected as control group. All the participants took anteroposterior and lateral knee radiographs through PACS imaging systems to collect six imaging indexes, including install index, the degree of tibiofemoral joint subluxation, tibiofemoral inside and outside joint clearance ratio, femoral angle, tibial angle and tibiofemoral angle. Knee osteoarthritis patients in pain group were divided into two common clinical pain areas which were proparea and medial area.

RESULTS AND CONCLUSION: (1) The insall index, the degree of tibiofemoral joint subluxation, tibiofemoral inside and outside joint clearance ratio between knee osteoarthritis patients in pain group and people in healthy control group had significant differences. There was no statistical significance in the femoral angle, tibial angle and tibiofemoral angle. (2) In terms of the comparison between proparea and medial area in knee osteoarthritis patients in pain group, tibiofemoral joint subluxation degree was statistically different. (3) These findings suggest that there was a higher patella in knee osteoarthritis patients who were in pain, more severe in the degree of tibiofemoral joint subluxation, and more limited in tibiofemoral inside and outside joint clearance ratio. The degree of tibiofemoral joint subluxation of proparea was more severe than medial area in pain group.
