<s>[INST] I have had a knee replaced (same knee) twice and a patella ligament tear and repaired using same ligament. Than my ligament stretched and knee cap moved, couldn t raise that leg very high and another surgery was done to tighten my tendon & placed an other cadaver ligament. two years later and still in pain at times an 8 or 9. only an xray done to verify knee replacement seems to be OK. Also had pain management to no avail, and only more pain.?? what to do, where to go???? I know Dr Kumar if you are the one that studied at AHI???? [/INST] Dear sir/mamthis may be bold because  you need to provide more information but sometimes after the tear from the patelar ligament the pain comes from the patela and sometimes there is the need even for the patela to be replace if i can say so. </s>
