In all cases examined brittle failure in the glass beams was observed due to stress concentration near the hole, highlighting the importance of the choice of an adequate distance from the hole and the edges of the beams and of the study of an appropriate interface material for connections between glass panels and steel members in the case of both preloaded and non-preloaded bolts.
While the knee was held in extension, a circular wire was passed from the tunnels and tightened until obtaining an adequate distance between the patella and the tibial tuberosity, considering the Insall-Salvati ratio (normal length of the patellar tendon is approximately equal to the length of the patella) [9].
