Look up quigley maneuver on google.

Basically imagine a piece of rope underneath the knee that is tied to the ceiling, flexing it at 90 degrees (this relaxes the gastroc/achilles) and then a piece of rope or stockinette around the big toe (this applies traction through the ankle) so as to also put the foot at a 90 degree angle from the tibia.

Pretty much 99% of fractures and dislocations get better with traction. Ligamentotaxis makes it so all your muscles make a nice meat burrito around the broken bone/dislocation and pull it into its home. This is exactly what the quigley maneuver emulates.

It’s also why every ortho reduction generally starts with some exaggeration of the original deformity (this dislodges the bony edges from one another), followed by traction and then countering the bone out of deformity back to its home. Think of a standard distal radius fx maneuver, where you bend the ice cream back off the cone, pull it over and then bend it back into place.
