Abstract

PURPOSE: Meniscocapsular(MC) separation in knee joint can deteriorate joint function and must be repaired in arthroscopy. We investigated retrospectively MR imaging findings in order to find out its validity for accurate diagnosis & early treatment.
MATERIALS AND METHODS
From Jan. 1998 to Dec. 1999, among the patients treated with MC tear under the arthroscopy, MRI findings was evaluated in 31 patients(18 cases: medial, 13 cases: lateral) at retrospectively.
RESULTS
The important findings in medial meniscus were that fluid collection meniscus and MCL was 12 cases(67k) and increased distance between meniscus and capsule was 10 cases(56%), but in lateral meniscus, perimeniscal swelling was 10 cases(77%), and menisco-tibial extension rupture was 8 cases(62%).
CONCLUSION
The important MR findings for the MC tear were the increasing distance or fluid between meniscus and joint capsule or MCL at medial meniscus, and perimeniscal swelling, menisco-tibial extension rupture at lateral meniscus.
