<s>[INST] I need a knee replacement but I m very scared. was told my legs are to big with fat and could get bold clots and die. I have bone on bone and wearing a hole in bottom bone. Lots of arthristis (sp wrong).. Don t know what to do? Have no life. Can t hunt with my husband. [/INST] I understand getting any operation done is scary , there are some details which are missing to guide you properly , your age , your weight ,exact xray report , how much compression is there??? have you tried conservative treatment before and for how long? If you are really not in favour of going for knee replacement , these are the things you should work on 1.reduce your weight (knee joint is a weight bearing joint , even 2 kgs reduction will make a difference )2.hot fomentation3. strengthening exercises for knee as guided by physiotherapist.4.calcium rich diet5. continue walking if all this helps you by 50% at-least continue with it otherwise knee replacements are good answer to improve your quality of life. </s>
