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 (“consisten ...
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 ...
Aims The objective of this study was to compare the two-year migration and clinical outcomes of a new cementless hydroxyapatite (HA)-coated titanium acetabular shell with its previous version, which shared the same geometrical design but a different manufacturing process for a ...
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 migra ...
