Purpose : To assess the MR findings of chondromalacia patella and correlate the grade
and associated lesions with the arthroscopic findings.
Materials and Methods : Twenty-five patients with pain in the anterior part of the
knee underwent fat-suppressed axial and coronal T2-weighted, dual echo sagittal proton
density-weighted and T2-weighted, and in some cases, T1-weihgted and T2-weighted
imaging, using a 10cm field of view, and a 5-inch general puneral pirpose coil. We
retrospoctively assessed these find dings, and the locations, tirades and associated
lesions, and correlated these with the arthroscopic findings.
Results : Fourteen cases (56%) of chondromalacia patellae were arthroscopic grade I /
¥±, nine (36%)were grade ¥², and two(8%) were grade ¥³: associated lesions were
medial synovial plicae(16 cases, 64%), meniscus tear(10: 40%), dreciate ligament
injury(two: 8%), complete or incomplete discoid miniscus(four: 16%), bipartite patella
(one :4%) and Osgood-Schlatter disease(one:4%). In 24 cases, MR imaging indicated
chondromalacia patella :17 cases were grade 1/¥±, five were grade ¥², and two were
grade ¥³. The location of chondromalacia patella was the medial facet(five case:20%),
lateral facet(three :12%), junction of the medial and odd facet(13:52%), and diffuse
involvement (four ,16%). The sensivity and specificity of MR imaging were 72% and
96% respectively.
Conclusion : We evaluated the exact location and grade of chondromalacia patella and
associated lesions, as seen on MR images. These and the arthroscopic findings showed
close correlation, and in cases involving this condition, MRI is thus a useful indicator of
an appropriate surgical method and plan.(J Korean Radiol Soc 1998:38: 345-350)
