2. Fig 1
(A) FE mesh (59,874 elements) of soft tissue around the midpatellar tendon region and indenter. (B) Peak stress value showing the tendency to converge as the number of elements increases, with the soft tissue at the midpatellar tendon being indented to an extent that pain was just initiated.
