Is Unicompartmental Knee Having a Moment?

Apparently so, according to a new review of epidemiological trends and outcomes among knee arthroplasty patients in the United States. This new study out of Case Western Reserve, titled “Epidemiological Trends and Outcomes of Unicompartmental Knee Arthroplasty Among 104 Million Patients in the United States,” appears in the December 2024 edition of The Journal of Arthroplasty.

“Our primary motivation for examining trends in unicompartmental knee arthroplasty utilization stemmed from the relatively recent relaxation of patient selection criteria, which now accommodate for younger individuals (patients as young as 50) and those with higher BMIs [body mass index] (patients with BMIs as high as 40),” explained lead author Parshava Sanghvi, an M.D. candidate at Case Western Reserve University School of Medicine in Cleveland, Ohio.
