Do I need a foley catherter inserted if i'mhaving knee surgery?

Whether you need a Foley catheter for knee surgery depends on the specific procedure and your surgeon's preferences. Generally, Foley catheters are used during surgeries that may involve longer anesthesia or when patients are unable to use the bathroom afterward. It's best to discuss your individual case with your surgeon or anesthesiologist to determine if a catheter is necessary for your situation.
