The knee is susceptible to dislocation, and it sometimes dislocates for no greater reason than fast walking or a slight slide, just as the jaw dislocates for no reason other than yawning. The knee dislocates in all directions except in front, due to the patella that prevents this.
The patient is placed on a bench, close to the ground, and his legs are slightly raised. Then a strong man pulls his arms firmly up and down, and the chiropractor returns the joint to its place according to the general laws of treating dislocations and makes a bandage.
