Midlands Orthopaedics & Neurosurgery

#1 in Hip Resurfacing in North America

 updated 2/2023

Over 6800 hip resurfacings:

  • one of the first surgeons in the US to begin metal-on-metal hip resurfacing in 1999
  • led the first US FDA trial on hip resurfacing leading to approval of the Corin Cormet 2000 device in 2007.
  • developed the Biomet Magnum and recap systems for hip replacement and resurfacing and began using these in 2005.
  • began using the world’s first completely uncemented (Biomet) system for resurfacing in 2007. And have performed over 5800 uncemented resurfacings to date, while most surgeons still rely on inferior cement fixation of the femoral component.

Do our competitors post their results online?

The most important factor in achieving a successful result is the surgeon’s skill. You can only assess this from published data. We publish our results on this website (patient education / latest data) and in scientific journals (see all of my publications in the section: patient education/scientific publications). 99% 13-year implant survivorship in 5500 cases using the Biomet uncemented resurfacing system (99.3% in men and 98.3% in women). These are results in all comers… not just selected lowest risk patients (men with osteoarthritis). This compares favorably with the recent National Joint Registry report from Great Britain where a similar 92% overall 8-10 year survivorship is reported for both the cemented Biomet and BHR hip resurfacing systems.

It also compares favorably to benchmark data of all three major joint registries (British, Swedish, and Australian) for THR where the mean patient age is 70 and implant survivorship sits at approximately 95% for 10 years. For younger patients, 10-year benchmark data for THR falls off to a dismal 80% at 10 years for patients under 50 years age.

Outpatient surgery?

We have pioneered outpatient joint replacement surgery at Midlands Orthopaedics and neurosurgery. We began in 2012 and have performed thousands of joint replacements of all kinds in the last 8 years. We have now perfected this to the point that most of my joint replacements are done as outpatient procedures. Local patients go home several hours after the operation and follow-up with me in the office 1 week later. Out of area patients go to a hotel instead where I see them the next morning before they begin their drive home. Only patients with certain serious comorbidities or those with uncooperative insurance plans are still done at the hospital.

Most patients who have had one procedure done at the hospital and another as an outpatient much prefer the latter. The outpatient approach is safe, convenient, friendly, less costly, and avoids exposure to hospital infections. One requirement to qualify for outpatient surgery is to bring a capable and responsible caretaker (family or close friend at least 18 years of age) with you.

The physicians and physical therapy department at Midlands Orthopaedics & Neurosurgery will ensure the most comprehensive approach to help find relief for you in the quickest way possible.
