Dr Khanna has always been a straight shooter, with extreme compassion for how pain affects all aspects of life. The disc replacement at C4 that he did for my husband helped tremendously. He is now five months post-op and he continues to feel improvement. Dr. Khanna was also able to re-create more of the normal curve of the neck which was damaged long ago from a car accident. This has improved my husband’s posture which will help him in the long run.
