In orthopedics, weight-bearing is the amount of weight a patient puts on the leg on which surgery has been performed. In general, it is described as a percentage of the body weight, because each leg of a healthy person carries the full body weight when walking, in an alternating fashion.

Non-weight-bearing (NWB): The leg must not touch the floor and is not permitted to support any weight at all.[1] The patient may hop on the other leg or use crutches or other devices for mobility. In this grade, 0% of the body weight may be rested on the leg.
Touch-down weight-bearing or Toe-touch weight-bearing: The foot or toes may touch the floor (such as to maintain balance), but not support any weight.[1] Do not place actual weight on the affected leg. Imagine having an egg underfoot that one is not to crush.
Partial weight-bearing: A small amount of weight may be supported by the affected leg.[1] The weight may be gradually increased up to 50% of the body weight, which would permit the affected person to stand with his body weight evenly supported by both feet (but not to walk).
Weight-bearing as tolerated: Usually assigned to people that can support from 50 to 100% of the body weight on the affected leg, the affected person independently chooses the weight supported by the extremity.[1] The amount tolerated may vary according to the circumstances.
Full weight-bearing: The leg can now carry 100% of the body weight, which permits normal walking.[1]
