Every person's body is slightly different. Some tricks that work for certain people's hips don't always work for others.
If you have a medical condition or would like to try and pop your hip without getting on the ground, a stretch that should get the same result is the 'crane' yoga stance. In this stance, you stand on one leg and place the bottom of your foot on the inside of your opposite thigh, bending your knee outwards so your leg is parallel from your waist. Once you're in this stance, put your palms together against your chest as if you are praying, and slowly stretch your arms up, straightening your back.
