Medial ve Lateral Menisküslerin Radyal Yırtıklarında MRG ve Eşlik Eden Diz Eklemi Patolojileri

GİRİŞ ve AMAÇ: Bu çalışmanın amacı, medial ve lateral menisküslerde izlenen radyal yırtıkların manyetik rezonans görüntüleme (MRG) bulgularını ve bu yırtık tipinin, eşlik eden diz patolojileri ile ilişkisini ortaya koymaktır. YÖNTEM ve GEREÇLER: Bu çalışmada retrospektif olarak 30 hastanın MRG incelemesi PACS üzerinde değerlendirildi. MRG bulguları retrospektif olarak kas iskelet tercübesi olan 2 radyolog tarafından yorumlandı. Çalışmaya, pür radyal yırtığı olan hastalar dahil edildi. Diz MRG incelemeleri yapılmış ve radyal yırtık tespit edilen 30 olgu belirlenerek verileri kaydedildi. 30 hastadan 22'si merkezimizde atroskopik operasyon geçirmiş olup, 22'sinde de MRG bulguları ile uyumlu şekilde radyal yırtık olduğu konfirme edildi. BULGULAR: 30 olgunun 17'sinde medial menisküste (%56,7), 13'ünde lateral menisküste (%%43,3) radyal yırtık saptadık. Medial menisküste 11 (%36,7) olguda ekstrüzyon (≥3 mm), lateral menisküste 7 (%23,3) olguda ekstrüzyon görülmektedir. Bu çalışmada, radyal yırtığa en sık eşlik eden ligaman patolojisi ön çapraz bağ (ÖÇB) (17 olgu %56,9) olarak saptanmıştır. Radyal yırtık ile kıkırdak patolojileri arasındaki ilişki değerlendirildiğinde; En sık medial patellar fasette (MPF) 26 (%86,6) kondromalazi saptandı. TARTIŞMA ve SONUÇ: Radyal yırtıklar sıklıkla medial menisküste meydana gelirler. Medial meniskal radyal yırtıklarda mediale ekstrüzyon (≥3 mm) sık eşlik ederken, lateral meniskal radyal yırtıklarda laterale ekstrüzyon daha az rastalanılır. Radyal meniskal yırtıklarda en sık ligaman patolojisi, arka çapraz bağda görülür. Radyal yırtık ile dejeneratif kıkırdak hastalığı ilişkisinde, en sık MPF kıkırdağının etkilendiği izlenmektedir. Medial menisküs ekstrüzyonu ile kıkırdak dejenerasyonu arasında belirgin ilişki mevcut iken, lateral menisküs ekstrüzyonu ile kıkırdak dejenerasyonu arasında belirgin ilişki korele edilemedi.

Mrı and Accompanying Knee Pathologies in the Radial Tears of Medial and Lateral Menisci

INTRODUCTION: The aim of this study is to demonstratemagnetic resonance imaging (MRI) findings of radial tearsthat are seen in the medial and lateral menisci and therelationship between this tear type and other accompanyingknee pathologiesMETHODS: In this study, the MRI examinations of 30 patientswere evaluated on PACS retrospectively. The MRI findingswere interpreted by two different radiologists who wereexperienced in musculoskeletal radiology. Only the patientswho revealed radial tears on MRI were included in the study.Out of 30 patients,22 underwent arthroscopic operation in ourcenter and all of them were confirmed to have radial tears inaccordance with the MRI findings.RESULTS: Extrusion (≥3 mm) was observed in the medialmeniscus of 11 cases (36.7%) and in the lateral meniscus ofseven cases (23.3%). In this study, the most commonaccompanying ligament pathology was in the anterior cruciateligament (ACL) (17 cases, 56.9%). When the relationshipbetween radial tear and cartilage pathologies was evaluated;cartilage degeneration frequently was found in the medialpatellar facet (MPF) of 26 cases (86.6%) patients.DISCUSSION AND CONCLUSION: Medial meniscal radialtears are frequently accompanied with extrusion to medial (≥3mm). ACL pathology is the most common ligament pathologyin radial meniscal tears. It is observed that MPF cartilage arefrequently affected in relation to radial tear and degenerativecartilage disease. There is a significant relationship betweenmedial meniscal extrusion and cartilage degeneration.
