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.
This method of recovery has remained the main source of helium since. Helium is colorless, odorless, non-toxic, non-corrosive and non-combustible. Helium has the lowest boiling point of any substance , 4.2 Kelvin or â269 Â°C and as a result, liquid helium is the coldest matter on Earth.
