My knee was injured long time ago and my meniscus? - magnetic knee strap

cartleage truncated. MRI shows no cartleage between the bones. I was told I needed knee surgery in two parts. Is there an alternative method such as injection of stem cells to develop cartleage to its knees? Can anyone give a reliable answer, and if so, please tell me the website / email / e-mail phone / location. Thank you.
