Creating an informed patient requires reliable, unbiased, and user-friendly joint and bone health resources throughout the patient engagement process. One of the newest American Academy of Orthopaedic Surgeons (AAOS) patient offerings is the American Joint Replacement Registry (AJRR) Patient-Facing Interim Report. It joins an array of other AAOS patient education resources including the popular OrthoInfo website (over 3 million visits monthly) and the AAOS Registry Program Blog featuring orthopaedic patient stories from guest bloggers. Each of these offerings add a unique perspective to maintaining bone health, treatment options, and expected outcomes. All three resources (plus more) are detailed below and available to your patients.


2018 AJRR Patient-Facing Interim Report 

AJRR Patient-Facing Interim Report CoverThe AJRR Patient-Facing Interim Report was created to share highlights from the 2018 AJRR Annual Report that are meaningful and understandable to a patient audience. A team composed of surgeon leaders, the AAOS Registry Program Public Advisory Board, and AAOS Registry department staff prepared the document to convey:

  • An overview of the AJRR and why registries are important
  • The kind of information that is in the Registry and how it is used
  • Hip and knee replacement descriptions and results (data from 2012 to 2017)
  • A description of patient-reported outcome measures and their significance
  • A list of other helpful orthopaedic patient resources


A Sampling of Key Content

Hip Diagram

(AJRR Hip Sample 2012 - 2017)

  • The average age for first-time hip replacements in 2017 was 65.5 years of age
  • The average age of patients undergoing revision surgery was 67.4 years of age
  • The need for early revision (done less than three months from the initial procedure) is linked to either a patient's comorbidity, the presence of another disease or condition, or a complication from the procedure, such as dislocation, infection, or fracture


Knee Diagram

(AJRR Knee Sample 2012 - 2017)

  • The average age for patients undergoing a primary knee replacement in this sample was 66.8 years
  • Among all "linked" revisions, most were done from 6 - 12 months after the initial surgery*
  • For all early revisions, completed within three months of the initial surgery, the most common reason was due to either infection or an inflammatory reaction

*Linked revisions refer to other existing factors present in some knee arthroplasty patients that experienced an early revision, such as: a patient's comorbidity, the presence of another disease or condition, or a complication from the procedure

However, their understanding of a chosen treatment and their recovery expectations are often influenced by information from others who have undergone similar treatments. Below are some of our most popular Registry guest blogs sharing first-person orthopaedic patient stories. The patient stories featured in the blog are also noted in the Patient-Facing Report. You can link to any of the guest blogs below from your website making them easily available to your patient population:

Data Snapshot

Did you know? In AJRR's sample, femoral head size usage patterns have remained relatively constant between 2012 and 2017, with 36 mm heads used in approximately 58% of the primary THA procedures performed. The increased stability afforded by larger heads coupled with diminished volumetric wear concerns when these heads are used with highly cross-linked or enhanced polyethylene liners generally explains their sustained popularity.
