What does it mean if my knee has been numb for 5 months now? I'm 19 year old female. I'm 5'2" and weight 210 lbs. I've had 10 procedures/surgeries done since I was 15 months old (5 eye surgeries, 2 knee surgeries, appendix, shoulder surgery, and oral surgery to get a tooth down from my gums). It has been 5 months since my second knee surgery which was a Medial Patella Femoral Ligament Reconstruction. Since the second knee surgery I haven't been able to feel my knee because it's still numb over the kneecap.
