Total Knee Replacement has been in use for more than 50 years, although it is relatively recently that better understanding of the biomechanics of the knee has resulted in more advanced knee replacement devices that provide the patient and surgeon with a wider choice of treatment options for arthritis of the knee joint. More patients now want to know what those treatment options are, and to have a better understanding of the technology involved in knee replacement devices. Within My Knee you can find out exactly what Knee Replacement involves and about the different technologies which are now available to the surgeon and patient.    These include two kinds of Total Knee Replacement (fixed bearing and mobile bearing) and Unicompartmental Knee Replacement, where just one part of the knee is replaced in cases where the whole joint is not affected by arthritis.   In the Case Studies section you can read the personal stories of just a few of the patients who have had mobile bearing Total Knee Replacement or Unicompartmental knee replacement. The information contained within this site has been designed for you – the patient – and is presented in lay terms with the intention of helping you to make an informed choice with regard to your choice of treatment, in consultation with your orthopaedic surgeon.
