The role of hydrogen peroxide in hip arthroplasty
Andrew Kailin Zhou, Milind Girish, Azeem Thahir, Jiang An Lim, Caitlyn Tran, Shaan Patel, Matija Krkovic
Jun 29, 2022
Hydrogen peroxide has become more commonly used in hip arthroplasties due to high risk of periprosthetic infections. Its purported roles include irrigation, haemostasis, reduction of aseptic loosening and attachment of...
Influence of consciousness, muscle action and activity on medial condyle translation after Oxford unicompartmental knee replacement
E. C. Pegg, J. Bare, H. S. Gill, H. G. Pandit, J. J. O'Connor, D. W. Murray, A. J. Price
Dec 01, 2015
Background
Quantification of the in vivo position of the medial condyle throughout flexion is important for knee replacement design, and understanding knee pathology. The influence of consciousness, muscle action, and...

Fracture of mobile unicompartmental knee bearings
Cases of fractured mobile unicompartmental knee bearings have recently been reported. The purpose of this study was to understand the mechanics behind these fractures and to examine the influence of different design...
Approximation of the functional kinematics of posterior stabilised total knee replacements using a two-dimensional sagittal plane patello-femoral model
Previous in vivo studies have observed that current designs of posterior stabilised (PS) total knee replacements (TKRs) may be ineffective in restoring normal kinematics in Late flexion. Computer-based models can prove a useful...
Analysis of Pediatric Respiratory Disease Trends Using the 2016 KIDs' Inpatient Database
Many infants and young children worldwide have been affected by chronic respiratory conditions. In this paper, the authors performed an exploratory and predictive analysis of the 2016 KID data set to examine respiratory disease...

Optimal acetabular component orientation estimated using edge-loading and impingement risk in patients with metal-on-metal hip resurfacing arthroplasty
Stephen J Mellon, G Grammatopoulos, Michael Andersen, Hemant Pandit, Harinderjit S Gill, David Murray
Jan 01, 2015
Edge-loading in patients with metal-on-metal resurfaced hips can cause high serum metal ion levels, the development of soft-tissue reactions local to the joint called pseudotumours and ultimately, failure of the implant. Primary...
Preoperative pain location is a poor predictor of outcome after Oxford unicompartmental knee arthroplasty at 1 and 5 years
A. D. Liddle, H. Pandit, C. Jenkins, A. J. Price, C. A. F. Dodd, H. S. Gill, D. W. Murray
Nov 01, 2013
PURPOSE: Indications for unicompartmental knee arthroplasty (UKA) vary between units. Some authors have suggested, and many surgeons believe, that medial UKA should only be performed in patients who localise their pain to the...
Asymmetrical hip loading correlates with metal ion levels in patients with metal-on-metal hip resurfacing during sit-to-stand
Stephen Mellon, George Grammatopoulos, Hemant Pandit, David W Murray, Harinderjit S Gill
Jan 01, 2014
The occurrence of pseudotumours following metal-on-metal hip resurfacing arthroplasty (MoMHRA) has been associated with high serum metal ion levels and consequently higher than normal bearing wear. Measuring ground reaction...
