I hear of people getting these injections all the time. February of 2018, my right knee began to lock up and I went to the orthopedic. They submitted the paperwork for the orthovisc injections. I was told that it would take several weeks. They tried a few other brands that were cheaper when the insurance company denied the medication. Finally on April 28, 2018, my leg locked up and gave up the fight. When I went to see the doctor, I was told the shots were no longer an option and was scheduled for a TKR in 12 days. The same thing has happened with my left knee. In October, they tried to get the injections so that my left knee would be more stable as I recovered from shoulder surgery. It is now March 2019 and they have yet to approve it. So, I will be scheduling my left TKR and am hoping to wait until August. Insurance companies can be frustrating to say the least.
