For the management of unicompartmental osteoarthritis, researchers observed an increasing utilization of unicompartmental knee arthroplasty and a declining utilization of high tibial osteotomy, according to study results.
Researchers retrospectively reviewed the PearlDiver database between 2007 and 2011 for utilization data on unicompartmental knee arthroplasty (UKA) and high tibial osteotomy (HTO). Patient age, gender and region were extracted from the database, and the researchers used chi square analysis, logistic regression and parametric testing to perform statistical analysis.
Study results showed UKA was performed most frequently in patients between the ages of 60 and 64 years, whereas HTO was performed most frequently in patients between 40 and 44 years.
The likelihood of receiving UKA over HTO became significant when patients reached 50 years of age, as patients between 50 and 59 and those older than 60 were significantly more likely to receive UKA vs. HTO, according to the researchers.
The researchers also found women were most likely to undergo UKA, whereas men more frequently underwent HTO.
