Background: Loosening is a major cause for failure of total hip and total knee arthroplasties (THAs/TKAs). Preemptive diagnostics of asymptomatic loosening could open strategies to prevent gross loosening. A multitude of biomarkers may discriminate between loosened and sta

Tibial Baseplate Migration Is Not Associated with Change in Patient-Reported Outcome Measures and Clinical Scores after TKA
A Secondary Analysis of 5 Radiostereometric Analysis Studies with 10-Year Follow-up
Background:Radiostereometric analysis (RSA) provides highly accurate data about the migration of a total knee arthroplasty (TKA) component. However, patient-reported outcome measures (PROMs) reflect the patients' perspective of their functional status, pain, and overall health af

Influence of marker-selection method in radiostereometric analysis of total knee arthroplasty on tibial baseplate migration patterns
A secondary analysis of a randomized controlled trial with 5-year follow-up
Background and purpose — Different marker-selection methods are applied to represent implant and tibial seg-ments in radiostereometric analysis (RSA) studies of total knee arthroplasty (TKA). Either a consistent set of markers throughout subsequent RSA examinations (“consistent-m

Continued Stabilization of a Cementless 3D-Printed Total Knee Arthroplasty
Five-Year Results of a Randomized Controlled Trial Using Radiostereometric Analysis
BACKGROUND: Three-dimensional (3D) printing of highly porous orthopaedic implants aims to promote better osseointegration, thus preventing aseptic loosening. However, short-term radiostereometric analysis (RSA) after total knee arthroplasty (TKA) has shown higher initial migratio

Late stabilization after initial migration in patients undergoing cemented total knee arthroplasty
A 5-year followup of 2 randomized controlled trials using radiostereometric analysis
Background and purpose — In total knee arthroplasty (TKA), metal-backed (MBT) and all-polyethylene (APT) designs have shown comparable implant migration up to 2 years postoperatively using radiostereometric analysis (RSA). However, studies comparing mid-term migration of both des

The Influence of Postoperative Coronal Alignment on Tibial Migration After Total Knee Arthroplasty in Preoperative Varus and Valgus Knees
A Secondary Analysis of 10 Randomized Controlled Trials Using Radiostereometric Analysis
BACKGROUND: Orthopaedic surgeons aim for mechanical alignment when performing total knee arthroplasty (TKA) as malalignment is associated with loosening. Loosening may be predicted by migration as measured with radiostereometric analysis (RSA), but previous RSA studies on postope

Migration behaviour of 2 clinically excellent cementless stems with different design rationales
5-year follow-up of a randomised RSA-study
Introduction: Excellent long-term survival has been reported for both the Taperloc and the Mallory-Head cementless stems. However, little is known about the migration behaviour of these stems which have different design rationales. The purpose of this randomised clinical trial wa
...
BackgroundThe number of revisions after TKA is expected to rise because of aging populations in many countries and because patients are undergoing TKA at younger ages. Aseptic loosening is a major reason for late revision, which can be predicted by radiostereometric analysis (RSA
...
Background and purpose — Little is known about the long-term migration pattern of cementless stems in total hip arthroplasty (THA). Furthermore, the role of bioactive coatings in fixation, and thus migration, remains uncertain. Hydroxyapatite (HA) is the most commonly used bioact

Migration of a novel 3D-printed cementless versus a cemented total knee arthroplasty
Two-year results of a randomized controlled trial using radiostereometric analysis
Although bone cement is the primary mode of fixation in total knee arthroplasty (TKA), cementless fixation is gaining interest as it has the potential of achieving lasting biological fixation. By 3D printing an implant, highly porous structures can be manufactured, promoting osse

All-polyethylene versus metal-backed posterior stabilized total knee arthroplasty
Similar 2-year results of a randomized radiostereometric analysis study
Background and purpose — The all-polyethylene tibial (APT) component, introduced in the early 1970s, was surpassed by metal-backed tibial (MBT) trays as the first choice for total knee arthroplasty (TKA). With improved polyethylene, the modern APT components can reduce costs, and
...
Marker-based versus model-based radiostereometric analysis of total knee arthroplasty migration
A reanalysis with comparable mean outcomes despite distinct types of measurement error
Background and purpose — Pooling data of studies evaluating total knee arthroplasty migration using radiostereometric analysis (RSA) may be compromised when the RSA method used would influence estimated differences between groups. We therefore reanalyzed a marker-based RSA study
...
Palacos compared to Palamed bone cement in total hip replacement: a randomized controlled trial
RSA migration similar at 10-year follow-up
Background and purpose — Stability and survival of cemented total hip prostheses is dependent on a multitude of factors, including the type of cement that is used. Bone cements vary in viscosity, from low to medium and high. There have been few clinical RSA studies comparing the
