Fig. 3

Patterns of stress distribution at different flexion angles in the knee models with the TP or the modified TT technique. At 0° of flexion, the highest stress was seen on the anterior margin of the inner orifice of the tunnel in both groups. At 90° and 135° of flexion, the site of the highest stress moved to the posterior part of the inner orifice (A). The maximal stress concentration was also monitored around the outer orifice of the tunnel where the tendon was fixated in both groups (B). These figures are from a single representative specimen (TP group: upper column, modified TT group: lower column)
