I have had two knee replacements at Suburban Hospital in Bethesda, MD. I am a complicated patient because I am a chronic pain sufferer. As a result, after a major operation, the traditional methods used to manage pain must be reviewed and tweaked sometimes. With each knee replacement, Dr. Jach was asked to provide a pain consultation. I was extremely impressed with his knowledge, patience, understanding and willingness to help me through the first few days of recovery. I highly recommend Dr. Jach.
