The National Registries are often long, technical and very detailed – but they provide a great deal of useful  information.

Hip Resurfacing Report from AJRR 2016 Report

Hip Resurfacing at Surface Hippy Posted on by
Hip resurfacing represented less than 1% of the total hip arthroplasty procedures in our sample, as surgeons have moved away from the metal-on-metal articulations that predominated (Figure 19). This procedure remains highly concentrated among both hospitals and surgeons; in 2015, resurfacing was done in only 48 AJRR hospitals by 63 surgeons. One surgeon accounted for 117 of the 448 resurfacing procedures (26%), while another performed 52 procedures (11.6%). The majority (86.1%) of the resurfacing procedures were performed on males, consistent with
the practice in registries worldwide 7,8.

American Joint Replacement Registry Announced

American Academy of Orthopaedic Surgeons (AAOS) Creates Independent Organization 07/23/2009 Rosemont, IL The American Academy of Orthopaedic Surgeons (AAOS) has incorporated the American Joint Replacement Registry (AJRR), a nonprofit organization dedicated to collecting and reporting on hip and knee joint replacement procedures. AAOS believes this proposed option is a patient safety best practice. The goal of a national joint registry is to monitor device performance, thereby allowing early recognition of underperforming processes or devices and supporting continued clinical learning. “In 2009, AAOS has made great strides in bringing the American Joint Replacement Registry to reality. We have now incorporated. And, we currently are in the process of forming project work groups to tackle data, governance and oversight issues.” said John

The use of primary total
resurfacing hip replacement has declined for the
fourth consecutive year. There was a 22.1%
reduction in primary total resurfacing
procedures compared to 2009. Analyses on a
variety of factors affecting outcome have been
presented. These include primary diagnosis,
gender, age, head size and type of prosthesis.
Patients having a total resurfacing for
osteoarthritis are revised less frequently than
patients with developmental dysplasia. Females
have a significantly higher rate of revision
compared to males. Males have an age related
rate of revision, which is significantly higher
for patients 65 years or older.

As reported last year, the difference in outcome
related to gender is largely due to the size of
the femoral component. There is an inverse
relationship between rate of … Read the rest
