February 1, 2012AbstractBackground: The ability to return to sports activities (especially
running) after hip resurfacing arthroplasty seems to be very important for young
and active patients who have developed osteoarthritis.Purpose: To assess the quality of return to sports after hip resurfacing
arthroplasty by examining the time spent running, weekly mileage, and the
possibility of returning to competition in a series of patients.

Study Design: Case series; Level of evidence, 4.

Methods: A prospective, consecutive series of 202 patients (215 hip
resurfacings) was assessed to evaluate the possible resumption of running
activity (time spent, weekly mileage, return to competition). Of this initial
cohort, 40

I would like to take this opportunity to comment on the Lancet article, “Failure rates of metal-on-metal hip resurfacings: analysis of data from the National Joint Registry for England and Wales”, by Professor AW Blom, published on October 2, 2012.

First of all, this is an observational scientific study with valid research design and questions; however, the conclusions point out the limitations of registry studies (more on this to follow). Overall the conclusions of the study do NOT find any new information that has not already been known since 2010: that certain hip resurfacing implants perform better than others; that females do worse than males with hip resurfacing; and that larger size implants have a lower revision… Read the rest

Pat’s Corner – Hip Resurfacing is still an excellent option 2012 despite negative media

Hip Resurfacing at Surface Hippy Posted on by

I would like to comment, mostly for the people new to hip resurfacing, about the negative NY Times articles and other media against hip resurfacing. All of this information is one sided. The authors and some surgeons have an agenda against hip resurfacing. The retention rate of the BHR and other devices has been recorded and the records are available to the public. The first place to look are the national registries since they are actual statistics, not opinions:

Also watch the video interviews with the top hip resurfacing surgeons. They address all of this negative press and give a complete story to the success of hip resurfacing. Here are my interviews:

Metal-on-Metal Bearings by Dr. Rogerso 2014

Hip Resurfacing at Surface Hippy Posted on by

Updated 10/2/2014

Metal-on-metal (MoM), ceramic-on-ceramic (CoC), and ceramicized
metal-on-polyethylene (CMoP) bearings all were developed as a reaction to the
well recognized mediocre long-term results with metal-on-polyethylene hips in
younger, more active patients.

Polyethylene wear increases with increased
activity and load, and often elicits an aggressive response from the body where
loosening and bone loss occurs (osteolysis), making subsequent revision more
difficult.

Alternate bearings (MoM, CMoP, and CoC) are more resistant to
wear, and their wear debris does not usually appear to stimulate near as much
osteolytic bone loss response as does polyethylene wear. Metal-on-metal bearings
have the added benefit that they can withstand high impact without shattering,
as do ceramic heads, and the larger metal head sizes render them statistically
about 10 times more stable … Read the rest

Dr. Rogerson Replies to Dr. Kurtz Book and Opinions

Hip Resurfacing at Surface Hippy Posted on by

Dr. Kurtz had an article online that had concerns about the head neck rations of hip resurfacing compared to total hip replacement. We wanted to provide potential hip resurfacing patients with opinions of other top resurfacing surgeons to explain their views.

Vicky,

I read over the discussion of the head-neck ratios and
impingement that you forwarded which was very thorough.
There is no question that the head to neck ratios of a
total hip arthroplasty with a small diameter neck are
larger than with resurfacing arthroplasty, especially a
metal on metal big femoral head construct. This would
translate into less impingement and greater stability
which increases as the head size increases. If
biomechanics were the only factor involved in the choice
of a prosthesis then

THE DURABILITY OF HIP RESURFACING by Dr. Gross 2012

Hip Resurfacing at Surface Hippy Posted on by

Updated 10/2/2014 Thomas P. Gross, MD  13 years experience. Over 3000 cases.  For more information: www.grossortho.com

A recent Article in the Lancet medical journal has criticized hip resurfacing arthroplasty (HRA) as less durable than cemented 28mm total hip replacement (THR). I take exception to the inappropriate conclusion that the authors drew from this highly flawed study.

 

However, there are two conclusions that can be drawn from this study. Surgeons, who are inexperienced in hip resurfacing, have more revisions in the short term with resurfacing than if they stick with standard hip replacement. Women have a higher failure rate than men with hip resurfacing. Both of these are old news.

 

Hip resurfacing has several distinct advantages over stemmed small bearing total hip replacement. The … Read the rest

What is the Best Bearing Type? Dr. Thomas Gross 2011

Hip Resurfacing at Surface Hippy Posted on by
A comparison of modern bearing types Dr. Thomas Gross 1/11/2011

As a patient there are four reasons you should consider a metal-on-metal bearing total hip replacement or resurfacing:

1. WEAR: Low.

2. BREAKAGE: Unbreakable bearing. 

3. STABILITY: Maximum stability of the joint.  Using a metal-on-metal bearing surface allows the manufacture of a large bearing hip joint that will not dislocate. 4. BONE PRESERVATION: Resurfacing is only possible with this bearing type. This allows bone preservation and avoidance of a stem in the femoral canal.

Hip replacement has come a long way since the 1950’s. It has improved to the point where middle aged or older patients can expect a relatively long life out of the implants if they follow certain restrictions and don’t participate

Survivorship Rates for Hip Resurfacing from National Registries

Survivorship Rates for Hip Resurfacing from National Registries

Australian Orthopedic Association National Registry 2011

The cumulative percent revision at ten years for primary total resurfacing
hip replacement undertaken for osteoarthritis is 7.5%

Running Activity After Hip Resurfacing Arthroplasty

There are six prostheses with over 1,000 observed component years, the ASR,
Adept, BHR, Cormet, Durom and Mitch TRH. At seven years, the BHR has the lowest
cumulative percent revision (5.0%) compared to Cormet (11.1%), Durom (9.6%) and
ASR (13.0%). The BHR is the only resurfacing prosthesis with a cumulative
percent revision at ten years (6.3%).

Results of Hip Resurfacing by Dr. Brooks 2012

Updated 10/2/2014

Peter Brooks MD, FRCS(C) www.clevelandclinic.org 216-444-4284 brooksp@ccf.org

I have been performing hip resurfacing at Cleveland Clinic using the Birmingham Hip Resurfacing System (BHR) since 2006, shortly after it became the first resurfacing device to be approved by the FDA. Two of my partners perform BHR as well. We also perform total hip replacement (THR). I would agree with Dr Gross, “The Durability of Hip Resurfacing” on this site in his excellent rebuttal to an ongoing series of dubious studies and apples-to-oranges comparisons in the orthopedic literature, mass media, national registries, and personal series. I have been very pleased with the outstanding results of hip resurfacing when done in the right patient, using a properly designed device, with well placed implants. At this time,… Read the rest

New Clinical Results about the BIRMINGHAM HIP™ Resurfacing

Published Thursday, Feb. 09, 2012

LONDON, February 9, 2012 -PRNewswire/ – Smith & Nephew (NYSE:SNN; LSE:SN), the global medical technology business, today announced the results of a new study for its BIRMINGHAM HIP™ Resurfacing (BHR) System. The study, carried out at the request of the FDA, followed the progress of the first 400 BHR patients in the United Kingdom and found that after 10 years, 99% were either satisfied or extremely satisfied with their BHR procedure.

“These results further exemplify why the BHR Hip is unlike any other metal-on-metal implant,” says John Soto, Senior Vice President for Smith & Nephew’s Global Hip Franchise. “Not only does the BHR Hip offer all the advantages of hip resurfacing, including bone-conservation, greater range of motion and … Read the rest
