Knee arthroplasty implants are designed with features that provide varying articular
constraint over the range of flexion such that the pattern of knee motion may also vary …

Total knee arthroplasty is a well established treatment for degenerative joint disease, which
is also performed as a treatment in younger and middle-aged patients who have a …

X3 is a highly crosslinked ultrahigh molecular weight polyethylene (UHMWPE) produced by
a sequential irradiation and annealing process. The sequential process results in a material …

Initial implant stability is crucial to cementless knee arthroplasty fixation. The objective of this
study was to evaluate the stability of two baseplates with different fixation features: a …

Increased femoral knee component surface roughness is clinically and experimentally
correlated with increased ultra-high molecular weight polyethylene (UHMWPE) wear rates …

Aseptic loosening attributable to wear-related osteolysis historically has been the
predominant cause of failure in THA. Advances in low-wear bearing couples show great …

Metallic femoral components with ceramic articulating surfaces can substantially lower
polyethylene (PE) wear during walking activities under conditions of normal knee alignment …

Pain-free flexion of as much as 155 with stability is the ultimate goal of total knee
replacement (TKR). Achieving this amount of flexion depends on implant design, surgical …

The wear of ultrahigh-molecular weight polyethylene (UHMWPE) tibial inserts in total knee
arthroplasty (TKA) remains a major limitation that hinders the longevity of clinically …

Walking is only one of many daily activities performed by patients following total knee
replacement (TKR). The purpose of this study was to examine the hypotheses (a) that …
