Hip Squeaking after ceramic-on-ceramic Total Hip Arthroplasty

Chinese Medical Journal 2016年第15期129卷 1861-1866页

作者： Guo-Liang Wu Wei Zhu Yan Zhao Qi Ma Xi-Sheng Weng Department of Orthopaedic Surgery Peking Union Medical College Hospital Chinese Academy of Medical Sciences and Peking Union Medical College Beijing 100730 China

Objective： The present study aimed to review the characteristics and influencing factors of squeaking after ceramic-on-ceramic （CoC） total hip arthroplasty （THA） and to analyze the possible mechanisms of the audible noise. Data Sources： The data analyzed in this review were based on articles from PubMed and Web of Science. Study Selection： The articles selected for review were original articles and reviews found based on the following search terms： “total hip arthroplasty”, “ceramic-on-ceramic”, “hip squeaking”, and “hip noise.” Results： The mechanism of the squeaking remains unknown. The possible explanations included stripe wear, edge loading, a third body, fracture of the ceramic liner, and resonance of the prosthesis components. Squeaking occurrence is influenced by patient, surgical, and implant factors. Conclusions： Most studies indicated that squeaking after CoC THA was the consequence of increasing wear or impingement, caused by prosthesis design, patient characteristics, or surgical factors. However, as conflicts exist among different articles, the major reasons for the squeaking rernain to be identified.

Restoring Natural Hip Movements with Large Head (ceramic on ceramic) Total Hip Replacement: Experience of Our 150 Patients over 6 Years

Open Journal of Orthopedics 2017年第12期7卷 414-427页

作者： Sanjay Agarwala Mayank Vijayvargiya Sameer Chaudhari Department of Orthopedics P.D. Hinduja National Hospital Mumbai India

Background: Asian cultures require floor-seated positions demanding a high range of motion (ROM). ceramic-on-ceramic (COC) interface allowed the use of larger head with reduced wear debris generation and adverse tissue reactions. This study was conducted to analyze 6-year clinical-radiological outcome with large head fourth generation DeltaMotion®ceramic-on-ceramic (COC) hip articulation, with special emphasis on postoperative ROM, ability to sit cross-legged, stability, hip noise and revision surgery. Material and Methods: 150 consecutive hips were operated for primary cementless Total Hip Replacement (THR) using DeltaMotion®at a tertiary care center in Mumbai, India, between January 2010 and January 2015. Clinico-radiological outcome was assessed using the Harris Hip Score (HHS) and radiographs at 6 weeks, 6 months, and annually thereafter. Results: 108 (74.5%) patients were males and 37 (25.5%) were females with an average age of 50.87 years. Mean follow-up was 54 months (range: 37 - 86 months). The mean ROM was 120° in flexion, 10° in extension, 30° in adduction, 45° in abduction, 25° in internal rotation and 25° in external rotation. The mean HHS showed a statistically significant improvement of 64.5% (from 54.66 ± 6.42 pre-operatively to 89.95 ± 4.32 post operatively) (p-value: 0.001). 92% of patients were able to sit in squatting position and 92% were able to sit cross-legged on the floor at last follow-up. 0.7% joints (1 hip) had squeaking. Considering no revision surgery as the end point, 6-year prosthesis survivorship was 100%. Complications (superficial infection) occurred in three hips (2%). All patients reported to be satisfied with their outcome after surgery. Conclusion: We infer that DeltaMotion large head COC bearing allows scope for using larger head size in relatively smaller Indian hips due to factory fitted ceramic lining. At 6-year follow-up, high activity level was observed with excellent clinical-radiological outcomes and component lo
