Pain Management

We take pain seriously at Health Quest and have a pain management program designed to provide you relief and help you recover more quickly. Post-surgery pain control options include on-demand narcotics delivered orally or intravenously. Due to our use of a revolutionary nerve block that numbs an area without weakening the surrounding muscle, recovery from total knee replacements and other orthopedic procedures has become significantly less painful. For more information, see Pain Management.

Pre-Surgery Classes

The more you know about your surgery ahead of time, the more prepared you will be to face recovery. Therefore, we urge you and your loved ones to take advantage of our pre-surgery classes and seminars.

  • Pre-Operative Total Joint Replacement (TJR) classes are offered at all four Health Quest Hospitals and is an opportunity to learn how to prepare for surgery and meet members of the orthopedic team, including specially trained nurses, physical therapists, occupational therapists and case managers.
  • Nutrition classes teach you about health-supportive nutrition, emotional eating and small lifestyle changes that can make a big impact before and after orthopedic surgery.
