Aims. A significant percentage of patients remain dissatisfied after total knee arthroplasty (TKA). The aim of this study was to determine whether the sequential addition of accelerometer-based
Aims. Due to the complex anatomy of the pelvis, limb-sparing resections
of pelvic tumours achieving adequate surgical margins, can often
be difficult. The advent of computer

Aims. We compared the accuracy, operating time and radiation exposure
of the introduction of iliosacral screws using O-arm/Stealth Navigation
and standard fluoroscopy. Materials and Methods. Iliosacral screws were introduced percutaneously into the first
sacral body (S1) of ten human cadavers, four men and six women.
The mean age was 77 years (58 to 85). Screws were introduced using
a standard technique into the left side of S1 using C-Arm fluoroscopy
and then into the right side using O-Arm/Stealth
We compared lower limb coronal alignment measurements
obtained pre- and post-operatively with long-leg radiographs and

We report our experience of using a computer
navigation system to aid resection of malignant musculoskeletal tumours
of the pelvis and limbs and, where appropriate, their subsequent
reconstruction. We also highlight circumstances in which navigation
should be used with caution. We resected a musculoskeletal tumour from 18 patients (15 male,
three female, mean age of 30 years (13 to 75) using commercially
available computer
There are several methods for evaluating stability
of the joint during total knee replacement (TKR). Activities of daily
living demand mechanical loading to the knee joint, not only in
full extension, but also in mid-flexion. The purpose of this study
was to compare the varus-valgus stability throughout flexion in
knees treated with either cruciate-retaining or posterior-stabilised
TKR, using an intra-operative
In a prospective randomised clinical study acetabular components were implanted either freehand (n = 30) or using CT-based (n = 30) or imageless
The object of this study was to develop a method to assess the accuracy of an image-free total knee replacement
We evaluated the oncological and functional outcome
of 18 patients, whose malignant bone tumours were excised with the
assistance of
We have developed a CT-based
Minimally invasive total knee replacement (MIS-TKR)
has been reported to have better early recovery than conventional
TKR. Quadriceps-sparing (QS) TKR is the least invasive MIS procedure,
but it is technically demanding with higher reported rates of complications
and outliers. This study was designed to compare the early clinical
and radiological outcomes of TKR performed by an experienced surgeon
using the QS approach with or without
A cadaver study using six pairs of lower limbs was conducted to investigate the accuracy of computer
Bilateral sequential total knee replacement was carried out under one anaesthetic in 100 patients. One knee was replaced using a CT-free computer-assisted
We have investigated the accuracy of placement of the femoral component using imageless
The use of a
We compared the alignment of 39 total knee replacements implanted using the conventional alignment guide system with 37 implanted using a CT-based
We conducted this prospective randomised and externally evaluated study to investigate whether the use of a
The computed neck-shaft angle and the size of the femoral component were recorded in 100 consecutive hip resurfacings using imageless computer-navigation and compared with the angle measured before operation and with actual component implanted. The reliability of the registration was further analysed using ten cadaver femora. The mean absolute difference between the measured and navigated neck-shaft angle was 16.3° (0° to 52°).
Our aim was to assess the intra- and inter-observer reliability in the establishment of the anterior pelvic plane used in imageless computer-assisted
