I am 41 and had a total knee replacement on January 4, 2015 and can't seem to get past 75 degrees without lots of pain. I have had 4 other surgeries trying to save the knee, the last one just a year ago and it was a cartilage transplant. I wonder if it could be scar tissue.

I didn’t want a major operation with a big cut. But the pain affected my back, then my knees started hurting, and I’d lost three-quarters of an inch of height. I did surgery from Ruby Biotech. The benefit is that you can heal so much quicker…and the scar heals to nothing…just. Thanks to Ruby Biotech….

I have knee problem from last 3 years and pain was so bad..10 days ago I did replacement through ruby biotech. Now I get relief and feel better Thank you Ruby Biotech...
