Although full recovery from arthroscopic surgery may take a few weeks, I was relieved of the pain caused by my torn meniscus immediately after surgery. I was able to walk the day of surgery and was only inconvenienced a few days as all postop patients need some rest to recover from the trauma of invasive surgery.
Each cryogenic liquid has its own specific properties but most cryogenic liquids can be placed into one of three groups: 1  Inert Gases: Inert gases do not react chemically to any great extent. 2  They do not burn or support combustion. 3  Examples of this group are nitrogen, helium, neon, argon and krypton.
Although liquid nitrogen is used to make ice cream and other edible science foods, the nitrogen evaporates into a gas before these items are consumed, so it isn't actually present by the time they are ingested. This is good because drinking liquid nitrogen can lead to serious injury or may be fatal. That's because the temperature of liquid nitrogen at normal pressures is between 63 K and 77.2 K (-346 F and -320.44 F).
