Frequently Asked Questions

A surgery center (also known as an ambulatory surgery center, outpatient surgery center, same-day surgery center, or surgicenter) is a licensed, freestanding, outpatient health care facility where surgical procedures not requiring an overnight hospital stay are performed.

Some of the benefits of a surgery center include:

  • Access to same-day surgeries, so you can get back to your life faster
  • Reduced risk of hospital-acquired-infections
  • Shorter procedure times than in a hospital
  • Reduced stress (less time off work or away from family)
  • Increased affordability

The main difference between inpatient care at a hospital versus outpatient care at a surgery center is that for inpatient care you stay the night in the hospital. Hospitals are also open 24/7 whereas a surgery center is only open during business hours (e.g., 8:30 am to 5:00 p.m.).

For many musculoskeletal procedures, outpatient surgery can be a safe and less stressful experience than inpatient surgery. Overall, surgery centers are very safe with a low frequency of complications.

Ultimately, your doctor will tell you whether or not you are a good candidate for outpatient surgery, but it may be considered very safe for you if you are:

  • In overall good health
  • Not obese
  • Age 65 or younger
  • Having a minimally invasive or low-risk procedure

ou would not be a candidate for outpatient surgery if you are over age 65 and are considered overweight or obese or you have

  • Obstructive lung disease
  • Hypertension
  • History of heart attack or stroke
  • Previous cardiac intervention
  • History of prolonged operating room time during past surgeries

Part B of Medicare covers outpatient surgery if medically necessary. Talk to your healthcare provider to see if he or she thinks Medicare will judge the surgery to be necessary.

Rules about what Medicare covers can be confusing. For more information call 1-800-MEDICARE (1-800-633-4227) or visit the website at https://www.medicare.gov. You can also call your local Social Security office to ask questions about Medicare.

The surgical procedures performed at surgery centers are less invasive, lower-risk procedures like carpal tunnel release, arthroscopy, fracture treatment, meniscus removal, total joint replacement, etc.

The development of less invasive arthroscopic technologies has made it possible to move total joint replacement out of hospitals and into more convenient and cost-effective outpatient facilities.

In addition to lowering out-of-pocket costs, the biggest difference a patient will experience is a shorter length of stay. Patients are typically released from the surgery center to their home in the first 4 to 6 hours after surgery rather than the traditional hospital stay of 2 to 3 days. In addition, shorter-acting anesthesia is used when the patient is in surgery which allows for an easier recovery.

A 2014 American Academy of Orthopaedic Surgeons study showed same-day outcomes were comparable to those of patients admitted to the hospital and staying at least one night following surgery. Surgical site infection rates, a common complication leading to re-admission, is also much lower at surgery centers. According to The Centers for Disease Control, surgery centers have an infection rate that is less than half that of hospital inpatient facilities.

Over the past several years, we have seen many changes occur that brought us to the point that outpatient total joint replacement surgery is possible:

  • Advancements in surgical techniques–Incisions are smaller, reducing the likelihood of infection and pain
  • Improvements in anesthesia allow for rapid recovery and a shorter length of stay
  • Improvements in post-procedure pain management techniques with new longer-lasting local anesthetics and a pharmaceutical approach to limit the use of opioids
  • Improvements in family and patient education, preparation and follow- up

The benefits for patients having a total joint replacement at OSI include:

  • Lower Costs
  • Lower Infection Rates
  • Better Outcomes
  • Personalized Care
  • Shorter Stay
  • Recovery at Home

Outpatient total joint replacement is recommended for select patients who are healthy enough to have surgery in such a setting and have the appropriate home setting/support to allow them to be discharged in this manner.
