Knee arthroplasty in the young patient: survival in a community registry.

摘要: UNLABELLED Operative options for the younger patient with an arthritic knee remain controversial. We prospectively followed 1047 patients 55 years old or who underwent arthroplasty in a community joint registry over 14-year period. Patients were implanted joints of three predominant designs by 48 surgeons four hospitals associated registry. The mean age this cohort was 49.8 years, and 62.8% (657/1047) female. There total 73 revisions performed, 5.6% (37/653) women 9.2% (36/394) men. Cemented TKAs performed best, cumulative revision rate 15.5%, compared to 32.3% unicompartmental (UKA) 34.1% cementless designs. Men had higher than women, 31.9% 20.6%. Adjusting implant type gender, there no difference based on diagnosis (OA versus other) group (< = 40, 41-45, 46-50, 51-55 years) between cruciate-retaining -substituting Eighty five percent cemented TKA implants survived at 14 population under Cementless UKA increased risk independently.
