received call from this number, no caller ID name, no message left, called the number back and initially got a recording stating "for quality assurance this call may be recorded" , then someone answered "Advanced Knee Care" ... when I spoke to the woman and told her someone called me from this number but I don't recognize knowing this business, she said they believe someone has hacked (or spoofed) their number and has been using it (as the phone caller ID #) to call people, they are currently working with someone regarding this.
