« Cheese-wiring » effect of the steel frame at the level of the patella: 1: Orifice of the initial tunnel; 2: direction of the bone rail; 3: Orifice of the tunnel after “cheese-wiring” effect. A bone rail at both the patellar and the tibial levels was visible in the metal frame group and caused relaxation of the frame when returning to knee extension and therefore a loss of protection of ligament suture
