I am a 29 yo male and I love to play basketaball. In 2008, I had an ACL reconstruction surgery of my left knee. A few months ago, i began to have swelling in my left knee. Doctor I went to recommended an MRI. The MRI revealed that I had a “markedly diminutive” medial meniscus and an oblique tear in the posterior horn of my lateral meniscus. It also showed that I had degenerative changes beginning in my knee. I love to play sports and lift weights. I am afraid that if I continue to play and compete the way i do (and I want to continue as I enjoy it) I will end up with osteoarthritis which will limit my activities. Is there anything I can do to prevent osteoarthritis and still play and lift weights. I heard about the MACI cartilage repair procedure and Meniscus Transplant – Are these probable options for me?
