Magnetic Resonance Imaging and Arthroscopic Findings of the Popliteomeniscal Fascicles With and Without Recurrent Subluxation of the Lateral Meniscus
Arthroscopy, 03/30/2012Suganuma J et al.
A significantly high incidence of abnormal posterosuperior popliteomeniscal fascicle (sPMF) was found in RSLM and contralateral knees. Thus abnormal sPMFs existed in both knee joints before patients had locking symptoms, suggesting that abnormal sPMFs may be required for locking symptoms. A significantly high incidence of abnormal iPMFs was found only in the knee joints with recurrent subluxation of the lateral meniscus (RSLM). An abnormal anteroinferior popliteomeniscal fascicle (iPMF) is thus the essential lesion to allow the at–risk lateral meniscus to become unstable beyond the rate of control knees.
