Recent patent applications reveal an industry focus on developing acetabular solutions
While enabling technologies in joint replacement continue to be in the spotlight, clues revealed in the shadows of data point to niche focus areas for hip implant advancements. After examining the evidence in US patent applications filed since the beginning of the year, SmartTRAK identified a trend towards acetabular implant solutions. These solutions include implant designs that can address or potentially reduce the risk of acetabular bone loss or instability, often encountered in revision hip arthroplasty.
SmartTRAK’s US Hip Replacement Market Overview points out that revision hip procedure growth remains lower than that for primary hips due to the extended implant survivorship of next-generation implants and materials. However, revision hip procedures are expected to grow with a 5-year CAGR of +3.5% to nearly 110K procedures by the end of 2028. And, according to a paper by Sahil A. Sanghavi, MS, DNB, et al., acetabular bone loss continues to be one of the most challenging issues faced by orthopedic surgeons. (J Am Acad Orthop Surg, May 2024).
At least 15 patent applications published since January 1 are related to acetabular implant solutions. The line-up of patent subjects ranges from trial implants for more accurate cup placement during surgery to custom 3D printed augments with filings from large market players to designing surgeons. In Figure 1 below, SmartTRAK outlines the most recent acetabular implant-related patent applications.
