Aims. Robotic-assisted total knee arthroplasty (RA-TKA) is theoretically more accurate for component positioning than TKA performed with
Aims. The aim of this study was to compare robotic arm-assisted bi-unicompartmental knee arthroplasty (bi-UKA) with conventional
Aims. The aim of this study was to evaluate whether achieving medial joint opening, as measured by the change in the joint line convergence angle (∆JLCA), is a better predictor of clinical outcomes after high tibial osteotomy (HTO) compared with the

Aims. This study aimed to evaluate if total knee arthroplasty (TKA) femoral components aligned in either
Aims. The aim of this study was to investigate the distribution of phenotypes in Asian patients with end-stage osteoarthritis (OA) and assess whether the phenotype affected the clinical outcome and survival of
Aims. The aim of this study was to compare the post-operative radiographic

Extracorporeal irradiation of an excised tumour-bearing
segment of bone followed by its re-implantation is a technique used
in bone sarcoma surgery for limb salvage when the bone is of reasonable
quality. There is no agreement among previous studies about the
dose of irradiation to be given: up to 300 Gy have been used. We investigated the influence of extracorporeal irradiation on
the elastic and viscoelastic properties of bone. Bone was harvested
from mature cattle and subdivided into 13 groups: 12 were exposed
to increasing levels of irradiation: one was not and was used as
a control. The specimens, once irradiated, underwent mechanical
testing in saline at 37°C. The
Aims. We evaluated a large database with
We have previously reported the short-term radiological
results of a randomised controlled trial comparing kinematically
aligned total knee replacement (TKR) and
The cause of dissatisfaction following total
knee arthroplasty (TKA) remains elusive. Much attention has been
focused on static
Between April 2004 and July 2007, we performed 241 primary total knee replacements in 204 patients using the e.motion posterior cruciate-retaining, multidirectional mobile-bearing prosthesis. Of these, 100 were carried out using an image-free navigation system, and the remaining 141 with the conventional technique. We conducted a retrospective study from the prospectively collected data of these patients to assess the early results of this new mobile-bearing design. At a mean follow-up of 49 months (32 to 71), 18 knees (7.5%) had
The aim of this study was to determine whether exposure of human articular cartilage to hyperosmotic saline (0.9%, 600 mOsm) reduces in situ chondrocyte death following a standardised
Between October 2001 and September 2009 we lengthened 242 lower-limb segments in 180 patients using the Intramedullary Skeletal Kinetic Distractor (ISKD).
Aims. Patient-specific instrumentation of total knee arthroplasty (TKA) is a technique permitting the targeting of individual kinematic alignment, but deviation from a neutral
Correct positioning and alignment of components during primary total knee replacement (TKR) is widely accepted to be an important predictor of patient satisfaction and implant durability. This retrospective study reports the effect of the post-operative

An understanding of the remodelling of tendon is crucial for the development of scientific methods of treatment and rehabilitation. This study tested the hypothesis that tendon adapts structurally in response to changes in functional loading. A novel model allowed manipulation of the
In this study we used subject-specific finite
element analysis to investigate the
1. The structure and blood supply of the femoral head and neck, the mechanics of weight bearing, and the known effects of an inert foreign body are considered in relation to arthroplasty. 2. Some artificial hips are reviewed from the biomechanical standpoint. 3. From the information now available it is inferred that
