The questionnaire attached to this post is a compilation of questions derived from various scoring systems such as Tegner Lysholm Knee Scoring Scale OKS (Oxford Knee Score) Harris Hip Score and others. However, these are better used by doctors because they require some medical opinion in them to get an accurate score. 1: If you are not yet convinced you are bad enough to need joint replacement, print off a few copies of the form and complete them at monthly intervals so you can give yourself a time-lapse snapshot of your life. This should help you make up your mind. 2: If you have an appointment with a surgeon, your surgeon doesn't think you are ready for a replacement or thinks you are too young, print off the form, complete it and take it with you to your next appointment. Because of the source of the questions, it will be in a language with which he will be familiar. It also means he will have a very detailed description of your life and the difficulties you are having to cope with. If you print off the form, would you please click on the Agree icon (green tick) so I can see how many people are using it. Thank you.
