Is there any correlation between partially empty sella and chondromalacia patella, I m 28 years old lady, I ve been diagnosed with chondromalacia patella which is a result of muscle weakness as my doctor said. however, two months ago, I did Brain MRI, which results in partially emty sella, neurologist told me that it is normal, and there is no need to further work up. I want to know if there is any relation between PES and my knees pain.
