Abstract:
Objective To investigate the presence of radial displacement of the meniscus in knee joint, and discuses its clinical significance. Methods From January 2000 to February, 398 cases underwent MRI because of different symptoms, and were analyzed retrospectively. Of them, 312 were recruited to the study, whose age was more than 18 years without knee operation, serious deformity, bone destruction, fracture, dislocation and tumor. Non-weight-bearing magnetic resonance images (MRI) of 312 patients with symptoms, including 125 males and 187 females aging from 19 to 85 years, were used to evaluate retrospectively for the radial displacement of the meniscus in knees by Kenny's method. The macroscopic observation for menisci were noted separately during total knee replacement(TKR) and knee arthroscopy in 21 and 35 patients respectively. Results In the 312 cases, MRI examinations demonstrated that 52 patients were found with the radial displacement of the meniscus(16.7%),including 47 medial menisci and 6 lateral menisci. There was a statistically difference among each age group (?2=10.18,P
