Lower extremity gait kinematics outcomes after knee replacement demonstrate arthroplasty-specific differences between unicondylar and total knee arthroplasty: A pilot study KU Leuven
BACKGROUND: The aim of the present study is to compare sagittal gait kinematics of ankle, knee and hip joints between subjects with unicondylar and total knee arthroplasty and age matched healthy controls. Since unicondylar knee replacement is a less invasive procedure, which more closely preserves knee joint anatomy, we hypothesized that one year post unicondylar knee arthroplasty patients would demonstrate more normal gait patterns than ...
The use of computer-assisted orthopedic surgery for total knee replacement in daily practice: a survey among ESSKA/SGO-SSO members Ghent University
Computer-assisted orthopedic surgery (CAOS) for total knee arthroplasty is an emerging surgical tool, yet little is known about how it is being used in everyday orthopedic centers. We sought to better understand physicians' current practices and beliefs on this topic through performing a Web-based survey. Between December 2006 and January 2007, a 24-question survey was emailed to 3,330 members of the European Society of Sports Traumatology Knee ...
Femoral component loosening in high-flexion total knee replacement AN IN VITRO COMPARISON OF HIGH-FLEXION VERSUS CONVENTIONAL DESIGNS KU Leuven Ghent University
High-flexion total knee replacement (TKR) designs have been introduced to improve flexion after TKR. Although the early results of such designs were promising, recent literature has raised concerns about the incidence of early loosening of the femoral component. We compared the minimum force required to cause femoral component loosening for six high-flexion and six conventional TKR designs in a laboratory experiment. Each TKR design was ...
Early primary total knee replacement for complex proximal tibia fractures in elderly and osteoarthritic patients Vrije Universiteit Brussel
Complex intra-articular fractures of the proximal tibia are difficult to treat, especially in the elderly osteoporotic patient. Pre-existing osteoarthritis, cartilage damage during trauma, suboptimal reduction and fixation due to poor bone stock and/or secondary displacement frequently lead to poor outcome. After osteosynthesis rehabilitation is cumbersome as patients have been non-weight bearing for long periods of time and secondary total knee ...
Knee Load Distribution in Hip Osteoarthritis Patients After Total Hip Replacement KU Leuven
Reduced external knee adduction moments in the second half of stance after total hip replacement have been reported in hip osteoarthritis patients. This reduction is thought to shift the load from the medial to the lateral knee compartment and as such increase the risk for knee osteoarthritis. The knee adduction moment is a surrogate for the load distribution between the medial and lateral compartments of the knee and not a valid measure for the ...
Does pre-surgical central modulation of pain influence outcome after total knee replacement? Vrije Universiteit Brussel University of Antwerp KU Leuven
The aim of this study is to systematically review whether the presence of altered central pain modulation pre-surgical influences outcome after total knee replacement (TKR) in patients with knee osteoarthritis (OA), and if so which indices of central pain modulation predict poor outcome after TKR. To identify relevant articles, PubMed and Web of Science were searched. The search strategy was a combination of key words related to "Knee ...
Effect of femoro-tibial component size mismatch on outcome in primary total knee replacement University of Antwerp
Background: Most total knee arthroplasty systems allow a degree of femoro-tibial component size mismatch. We aim to investigate the influence of size mismatch on outcome after primary total knee arthroplasty. Methods: We reviewed 332 patients with cruciate-retaining Genesis II total knee arthroplasty with regard to femoro-tibial component size mismatch and Oxford Knee Score (OKS). We evaluated effects of Body Mass Index, gender and patellar ...
Is adapted measured resection superior to gap-balancing in determining femoral component rotation in total knee replacement? KU Leuven Ghent University
Obtaining a balanced flexion gap with correct femoral component rotation is one of the prerequisites for a successful outcome after total knee replacement (TKR). Different techniques for achieving this have been described. In this study we prospectively compared gap-balancing versus measured resection in terms of reliability and accuracy for femoral component rotation in 96 primary TKRs performed in 96 patients using the Journey system. In 48 ...
Tibial component in total knee replacement University of Antwerp
The aim of this study was to find a relationship between tibial overhang, malpositioning and oversizing, and the functional outcome. 188 patients were included in this retrospective study. All patients completed an Oxford knee score questionnaire at mean follow-up of 5 years. Anteroposterior radiographs of the total knee replacements were reviewed for medial and lateral overhang and oversizing. Lateral overhang was seen in 32.9% of patients with ...
