Fig. 3: MRI scoring system used. The MRI is graded from 0 to 69, with the higher number representing more severe grades of OA.

Features: BME (bone marrow edema) or Cyst, fat pad alt SI, fat pad signal intensity alteration. Location: Pat, patella; Troch, trochlea; LFC, lateral femoral condyle; LTP, lateral tibial plateau; MFC, medial femoral condyle; MTP, medial tibial plateau; aLM, anterior horn of lateral meniscus; bLM, body of lateral meniscus; pLM, posterior horn of lateral meniscus; aMM, anterior horn of medial meniscus; bMM, body of Medial Meniscus, pMM, posterior horn of medial meniscus; ACL, anterior cruciate ligament; PCL, posterior cruciate ligament; MCL, medial collateral ligament; LCL, lateral collateral ligament. Prefemoral, pre-femoral fat pad; Suprapatellar, suprapatellar fat pad; Hoffa’s, Hoffa’s fat pad. There was a total of 40 separate scores, adding up to the highest possible score of 69, representing the wort possible grade (that is, worst knee health). The MRI is graded from 0 to 69, with the higher number representing more severe grades of OA.
