The rotations and displacements during the activities were similar to those of moderate-to-high constrained fixed bearing knees.
In our current study, we compared the particle size and morphology of polyethylene wear debris between failed mobile bearing and fixed bearing knees.
We reviewed the incidence of patella clunk at mid-to-long-term follow-up of a rotating high-flex versus fixed bearing posterior stabilized TKA design.
In vitro wear simulation was performed according to ISO 14243-1 2002 (E) with the clinically introduced Univation® F fixed bearing unicompartmental knee design (Aesculap AG, Tuttlingen, Germany) made of UHMWPE/CoCr29Mo6 in a direct comparison to experimental gliding surfaces made of CFR-PEEK pitch and CFR-PEEK PAN.
We present the long-term results of a series of consecutive TKA Press Fit Condylar (J&J), cemented fixed bearing with selective patellar resurfacing in nonselected patients.
Citak et al. [5] demonstrated restored knee kinematics after performing a combined ACL reconstruction and fixed bearing UKA on cadaver specimens.
It is not clear in what proportion of knees fixed bearing devices can safely be used.
Pooled survivorship estimates were also compared with each type of insert (unconstrained fixed bearing, unconstrained mobile bearing, PS fixed bearing, PS mobile bearing, constrained condylar and all-polyethylene tibia) with cement fixation.
For this investigation, fixed bearing unicompartmental knee prostheses (Univation-F, Aesculap, Tuttlingen, Germany) were used with a metal on polyethylene articulation.
The early outcomes of 2 newer-generation posterior cruciate ligament-retaining fixed-bearing total knee arthroplasty (TKA) implant designs were assessed to determine if a single sagittal radius femoral design has an advantage in obtaining earlier knee range of motion and function when compared with a contemporary multiradius femoral design.
Moreover, the numerical results showed that the shear reinforcement, fixed bearing and the pier installed with the fixed bearing were more vulnerable to earthquake excitation than the shear studs, slide layer, and cement asphalt mortar layer investigated in this study.
