Journal ArticleDOI
Hands-on robotic unicompartmental knee replacement: A PROSPECTIVE, RANDOMISED CONTROLLED STUDY OF THE ACROBOT SYSTEM
Justin Cobb,Johann Henckel,P. Gomes,Simon Harris,M. Jakopec,F. Rodriguez,A.R.W. Barrett,Brian Davies +7 more
TL;DR: In this article, a prospective, randomised controlled trial of unicompartmental knee arthroplasty with the assistance of a robotic arm was conducted, where the authors compared the performance of the Acrobot system with conventional surgery.
Journal ArticleDOI
Pseudotumors in association with well-functioning metal-on-metal hip prostheses: a case-control study using three-dimensional computed tomography and magnetic resonance imaging.
Alister Hart,Keshthra Satchithananda,Alexander D. Liddle,Shiraz A. Sabah,Donald McRobbie,Johann Henckel,Justin Cobb,John A. Skinner,Adam W.M. Mitchell +8 more
TL;DR: A periprosthetic cystic pseudotumor was diagnosed commonly with use of metal artifact reduction sequence (MARS) magnetic resonance imaging in this series of patients with a metal-on-metal hip prosthesis.
Journal ArticleDOI
The painful metal-on-metal hip resurfacing
Alister Hart,Shiraz A. Sabah,Johann Henckel,Angus Lewis,Justin Cobb,Barry Sampson,Adam W.M. Mitchell,John A. Skinner +7 more
TL;DR: Metal artefact-reduction MRI, three-dimensional CT measurement of the position of the component and inductively-coupled plasma mass spectrometry analysis of cobalt and chromium levels in whole blood on 26 patients with unexplained pain following metal-on-metal resurfacing arthroplasty are carried out.
Journal ArticleDOI
Very low-dose computed tomography for planning and outcome measurement in knee replacement: THE IMPERIAL KNEE PROTOCOL
Johann Henckel,Robin R. Richards,K. Lozhkin,Simon Harris,F. Rodriguez y Baena,A.R.W. Barrett,Justin Cobb +6 more
TL;DR: By refining the CT scanning protocol, the effective radiation dose received by the patient is reduced down to the equivalent of one long-leg standing radiograph, which will be more acceptable to obtain the three-dimensional data set produced by CT scanning.
Journal ArticleDOI
Pseudotumors Are Common in Well-positioned Low-wearing Metal-on-Metal Hips
TL;DR: Pseudotumors were not associated with increased wear or metal ion levels, suggesting patient susceptibility is likely to be more important.
