TI  - Factors Related to Meniscal Extrusion and Cartilage Lesions in Medial Meniscus 
      Root Tears.

AB  - The purpose of this study was to identify factors affecting medial meniscus 
      extrusion and cartilage degeneration in medial meniscus root tears (MMRT) and to 
      determine the optimal cut-off values for the factors that predict disease 
      severity. We retrospectively evaluated 86 consecutive patients diagnosed with an 
      isolated MMRT by magnetic resonance imaging (MRI) examinations and arthroscopic 
      procedures for 2 years. Patient-specific factors such as age, sex, the time 
      between injury and MRI (mTIME), the time between injury and surgery (sTIME), the 
      time between MRI and surgery (dTIME), Kellgren-Lawrence (KL) grades, and the 
      mechanical tibiofemoral axis angle (mTFA) were documented. Regression analyses 
      and receiver operating characteristic (ROC) curve analyses were performed. The 
      mTIME was only positively correlated with meniscal extrusion (r = 0.425, 
      p < 0.001). The patients who had grades 3 and 4 cartilage lesions had only 
      significantly higher KL grades and longer sTIME than the patients who had lower 
      grades of cartilage lesion (6.5 months [interquartile range (IQ): 3.0-12.0) vs. 
      2.5 months [IQ: 0.9-3.9]; p < 0.001). The cut-off value of mTIME and sTIME were 
      2.5 and 6 months. Relapse times greater than 2.5 months and 6 months after a 
      specific event were associated with a 7.8-fold increased risk for meniscus 
      extrusion and an 18.2-fold increased risk for cartilage lesions, respectively. 
      The risk of medial extrusion of the meniscus and the severity of articular 
      cartilage lesions increased with time after an injury. The period of time from 
      2.5 to 6 months after traumatic event might be a critical window for intervention 
      in the patients with MMRT to perform the repair in the status which the meniscus 
      did not extrude more than 3 mm and the cartilage lesion did not progress more 
      than grade 3. This study is a retrospective and uncontrolled case series and 
      reflects level IV of evidence.
