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.
1 Flammable Gases: Some cryogenic liquids produce a gas that can burn in air. 2  The most common examples are hydrogen, methane and liquefied natural gas. 3  Oxygen: Many materials considered as non-combustible can burn in the presence of liquid oxygen. 4  Organic materials can react explosively with liquid oxygen.
