Background
knee arthroplasty, aseptic loosening of the tibial component, TKA
OSTEOARTHRITIS
Total knee arthroplasty (TKA) is commonly utilized to treat osteoarthritis, although aseptic loosening of the tibial component remains a primary concern [In order to increase the longevity of joint prostheses, researchers have explored various materials including cobalt chromium molybdenum, titanium, ceramic, and more recently, poly-ether-ether-ketone (PEEK) [The cement penetration depth is an important indicator of the quality and longevity of TKA. According to previous reports, cement penetration in well-performing TKA ranges from 2 to 4 mm [This study aimed to compare the effects of PEEK and CoCrMo knee prosthesis on cement penetration in the tibial bone and evaluate the short-term clinical outcomes and safety of PEEK TKA.
