Problem is, 100% sounds great, but 66% excellent outcome is down-right horrible compared to traditional total knee replacement, whose success rate is generally 98-99%. Newer technologies will definitely improve this over time, but my worry would still be the cement-bone interface, especially if you have pre-existing malalignment which, if severe, may require corrective surgery. The short of things is that the best part of your post was that you said taping is helping. I would stick to non-operative management for as long as you can and then broach the issue with your surgeon if the time does indeed come. Best of luck.
