主 题：patellofemoral joint osteoarthritis quadriceps femoris atrophy joint instability anterior cruciate ligament reconstruction
摘 要：High incidence of patellofemoral pain and patellofemoral joint osteoarthritis was found following anterior cruciate ligament(ACL)*** unstability of patellofemoral joint might be an important contribution *** study was designed to define the relationship between the unstability of patellofemoral joint and quadriceps femoris *** patients underwent MRI scan before ACL reconstruction and every two weeks after surgery,until 12 *** merchant’s patellar congruence angle,lateral inclination angle,and quadriceps femoris muscle cross-sectional area were measured and the relationship between the changes of angles and the ratio of quadriceps femoris atrophy was studied by multiple regression *** quadriceps femoris atrophy was observed after ACL reconstruction during the follow-up period of 12 *** merchant’s patellar congruence angle and lateral inclination angle significantly changed after *** alterations of the merchant’s patellar congruence angle were significantly correlated with the atrophy ratio of vastus medialis(coefficient=-5.76)and vastus lateralis(coefficient=8.35)during the follow-up period of 12 *** alterations of lateral inclination angle were significantly correlated with the atrophy ratio of vastus medialis(coefficient=20.62),vastus lateralis(coefficient=-11.38)and rectus femoris(coefficient=-0.469)during the follow-up period 12 *** sum up,ACL reconstruction can alleviate the dysfunction of patellofemoral joint to a certain ***,the unbalanced atrophy of quadriceps femoris once again destroyed the stability of patellofemoral joint following the operation,which might be one cause of patellofemoral joint pain and early onset of osteoarthritis after ACL ***,rehabilitation training that focuses on quadriceps femoris especially the vastus medialis shortly following operation is suggested.
