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

Risk Factors for Tibial Component Loosening
A Meta-Analysis of Long-Term Follow-up Radiostereometric Analysis Data
BACKGROUND: Radiostereometric analysis (RSA) is a highly accurate tool to detect implant migration and predict loosening following total knee arthroplasty (TKA). However, little is known about the predisposing risk factors for implant migration, nor which migration profile should
...
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 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

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
...
The Effect of Coronal Alignment on Tibial Component Migration Following Total Knee Arthroplasty
A Cohort Study with Long-Term Radiostereometric Analysis Results
Recent short-term studies of total knee arthroplasty (TKA) have claimed improved clinical outcomes and implant survival when aiming to restore constitutional joint kinematics, as compared with neutral mechanical axis alignment. However, implant durability may be compromised when
...
Migration and clinical outcome of mobile-bearing versus fixed-bearing single-radius total knee arthroplasty
A randomized controlled trial
Background and purpose — Mobile-bearing total knee prostheses (TKPs) were developed in the 1970s in an attempt to increase function and improve implant longevity. However, modern fixed-bearing designs like the single-radius TKP may provide similar advantages. We compared tibial c

Migration of all-polyethylene compared with metal-backed tibial components in cemented total knee arthroplasty
A randomized controlled trial
Background and purpose — With a rapidly increasing population in need of total knee arthroplasty (TKA), there is renewed interest in cost-saving all-polyethylene designs. Differences between metal-backed and all-polyethylene designs in initial component migration assessed by radi

Peri-apatite coating decreases uncemented tibial component migration
Long-term RSA results of a randomized controlled trial and limitations of short-term results
Background and purpose — Biological fixation of uncemented knee prostheses can be improved by applying hydroxyapatite coating around the porous surface via a solution deposition technique called Peri-Apatite (PA). The 2-year results of a randomized controlled trial, evaluating th

Fixation and clinical outcome of uncemented peri-apatite-coated versus cemented total knee arthroplasty
Five-year follow-up of a randomised controlled trial , using radiostereometric analysis (RSA)
Aims The optimal method of tibial component fixation remains uncertain in total knee arthroplasty (TKA). Hydroxyapatite coatings have been applied to improve bone ingrowth in uncemented designs, but may only coat the directly accessible surface. As peri-apatite (PA) is solution d
