Unicompartmental knee arthroplasty(UKA)is a commonly used and effective treatment for knee osteoarthritis(KOA)limited to a single compartment.With the continuous development of traditional cemented prostheses,and emerging cementless UKA prosthetic ma-terials,both kinds of prostheses have demonstrated significant clinical efficacy.In this article,we review and compare the design differences,clinical efficacy,associated complications,and use of new technologies in UKA between cemented and cementless UKA to comprehensively assess their clinical efficacy.
