Hi there!
Yes, knee issues could be related spinal issues as well if there is neural compression. Other possibilities that may need to be considered include chondromalacia, infections/ inflammations, arthritis, bursitis, tendonitis, cyst formation, bone growths/ tumours, nerve impingement/ compression, fractures, injuries to the internal knee ligaments/ menisci etc. I would suggest getting this evaluated by an orthopedician for an accurate diagnosis and appropriate management.
Hope this helps.
Take care!
