This patient had a recurvatum problem at the knee; so, the posterior shell might have been given to this patient to gain some time until the patient's knee flexors became stronger.
Breakaway torque is defined as the torque required to start a partâs rotation from a stationary position. It is usually a higher value compared to the maximum tightening torque value as per specification .
Torque is a force around a given point, applied at some distance from that point. In other words, it is a measure how much a force causes an object to rotate. Example of torque in action with a spanner and bolt. Letâs imagine we have a bolt that has rusted in place, and requires a torque of 3Nm before itâll budge.
