April Fool's! …Or Is It?

You might think we’re joking if we told you that knee replacement surgery can sometimes be done on an outpatient basis—meaning many patients go home the very same day.

But this is no joke.

Using the subvastus knee replacement approach, patients often experience less pain, faster recovery, and a quicker return home after surgery. In fact, outpatient knee replacement is routinely performed by Dr. Matthew Dwyer and Dr. Christopher Phelps at Orthopedic Performance Institute.

So while April 1st is known for surprises, this is one that’s very real—and very good news for patients needing knee replacement.

Call (210) 545-7171 to schedule an evaluation and learn if outpatient knee replacement may be right for you.

Everyone is familiar with using cold for pain relief. Now there’s iovera for joint pain, an FDA-cleared, outpatient focused cold therapy (or cryoneurolysis) procedure that freezes nerves to temporarily block pain signals.

The focused cold therapy with the iovera system delivers precise controlled doses of cold to targeted nerves which immediately stops pain signals from being transmitted to the brain. This is done without use of drugs or medications and does not permanently damage the nerves or surrounding tissue. Iovera is used to treat osteoarthritis joint pain and chronic joint pain.

To learn more about iovera, visit www.orthopedicperformance.com or call (210) 545-7171.

Thinking about hip replacement surgery? At OPI, Dr. Matthew Dwyer and Dr. Christopher Phelps perform the anterior hip approach, a minimally invasive technique designed for less pain, faster recovery, and fewer restrictions after surgery.

With the anterior approach, patients benefit from:
- Less muscle damage – Surgeons work between muscles rather than cutting through them, leading to less pain and faster healing.
- Lower risk of hip dislocation – Preserving natural stabilizing muscles helps keep the new joint secure.
- Improved range of motion – Get back to bending, moving, and crossing your legs with fewer limitations.
- Faster recovery & shorter hospital stay – Many patients start walking sooner and go home earlier.
- More precise implant placement – A better view of the hip joint during surgery leads to optimal results.
