The type of bone cement used during knee replacement surgery affects the outcome of that surgery. High viscosity bone cement (HVC) boasts shorter mixing and waiting times and longer working and hardening phases, meaning surgeons can handle and apply the cement earlier than with low- or medium-viscosity cements. Although HVC may be more convenient to use, there is mounting evidence that the bond it produces is not as strong. Researchers have observed more early failures with the use of HVC, even when used in combination with a previously well-performing implant. Complications associated with knee replacements performed with HVC include loosening and debonding (where the implant fails to adhere to the cement interface on the shin or thigh bone), which requires revision surgery. Other reported problems include new onset chronic pain and instability.

High-viscosity bone cement may sacrifice surgical...

A person usually opts for a total knee replacement (TKR) to regain their quality of life.

I never dreamed how much this would mean to me

I received another check today, much to my surprise. Thank you, thank you, thank you! I never dreamed how much this would mean to me in my golden years, as I have had hearing problems for years and needed to update my hearing aids, but with a limited income, found that was impossible. I now have the best hearing aids that I have ever had, thanks to you fighting so hard on my behalf.
