Here's the thing...I think we all have to decide how much 'pain' is adequate before deciding to go ahead with a surgery that will involve cutting of bone (bone 'cutting/sawing' or any type of injury to a bone is considered one of the most painful experiences...) unless there is something to alleviate that pain...and I'm not talking about pain medication, but more so, getting some type of relief of pain through intravenous methods..which they won't do anymore! In 2020, my husband's TKR involved a 'pain pump' intravenously pumping a type of lidocaine directly in to the knee (like the nerve block given before surgery) that lasted about 2 weeks and helped get him through the worst part of the surgery pain...It slowly gave him a numbing of the area and the pain was so much less than what they are making patients go through now! I totally believe that is why his surgery was such a success because he was able to do all of the exercises/stretches, etc, to heal correctly! The procedure works for most, but the $$ must be the reason they decided to stop doing it...and $$ is always the reason for everything...makes me crazy!
