Articular noise after THA using delta CoC bearings has little impact on quality of life
Journal of Arthroplasty Dec 17, 2020
Chatelet JC, Fessy MH, Saffarini M, et al. - This study was sought to present clinical results and survival at a minimum of 10 years of a consecutive series of uncemented total hip arthroplasty (THA) with fourth-generation ceramic-on-ceramic (CoC) bearings and ascertain the incidence of articular noises, their risk factors, and impact on quality of life (QoL). There were 25 revisions, 38 deceased, and 36 lost to follow-up from a series of 456 CoC THAs. Researchers evaluated the remaining 357 hips at 11.1 ± 0.7 years (range, 10-14) applying the Forgotten Joint Score, Oxford Hip Score, and a questionnaire on articular noises. They calculated Kaplan-Meier survival, and multivariable analysis was conducted to ascertain relationships between articular noise and patient/surgical factors. The effect of articular noises on QoL was negligible for most patients, out of 100 hips (28%) that reported some articular noises 10 years after CoC THA. Surgeons must be aware that increasing head size could also increase risks of articular noises, notably in young and active patients, although larger heads can improve mobility and reduce risks of dislocations.
