Chondroplasty is an option in cases of mild to moderate cartilage wear. During arthroscopy the loose cartilage flaps and debris within the knee are removed using an arthroscopic shaver. Great care is taken to avoid damaging normal cartilage.
Short Term Investments as Current Assets on the Balance Sheet. These are investments that a company plans to sell shortly or can be sold to provide cash. These short-term investments aren't as readily available as money in a checking account but they provide added cushion if some immediate need were to arise.
A business needs to be liquid enough to meet expenses, but not have so much cash on hand that short-term investment opportunities are not pursued. Companies often divide their assets into net liquid, quick, and current assets. Net liquid assets are what would be left if all of the businesses debts were paid off. Quick assets are those that can be converted into cash immediately, while current assets are those that can be converted within a year.
