Dearest Dr. Nasef, You performed a Total Knee Replacement for my right knee almost two years ago now. I am doing perfect with it Al hamdu lil ALLAH!!! I went to omra last year in Ramadan, and I am planning HAJ next year ISA. I lived before my operation in total depression for maybe three years because my knee hurt so bad, and I thought I would never be able to do those things except maybe on a wheelchair!!! Rabena yebarik fi ya tabiby!
