Radiological assessment of total and unicompartmental knee replacement remains an
essential part of routine care and follow-up. Appreciation of the various measurements that …

In hip replacement the use of hard bearing materials, which have been shown to have lower
wear rates than traditional metal-UHMWPE couples, has been encouraged in an effort to …

Purpose Dual mobility THA implantations are increasing. THA survival of more than 15 years
is considered long-term survival based on the Charnley prosthesis, which has a median …

Background: Metal-on-metal arthroplasty-related pseudotumors can cause severe local
destruction of bone and soft tissues. The cause of pseudotumors is unknown, although some …

Abstract Analysis of polyethylene (PE) wear in knee implants is crucial for understanding the
factors leading to revision in total knee arthroplasty. Importantly, current experimental and …

It is well known that wear occurring in polyethylene menisci is a significant clinical problem.
At this regard, wear tests on biomaterials medical devices are performed in order to assess …

Background Wear of polyethylene tibial inserts can decrease the longevity of total knee
arthroplasty. Wear is currently assessed using laboratory methods that may not permit …

In contrast to the articulating and taper surfaces of failed total hip replacements, volumetric
wear analysis of trunnions is not routinely performed. Metal wear particles from the trunnion …

Recently developed techniques have enabled volume loss measurements on surgically
retrieved total knee replacements (TKR). However, it is not well understood how volume loss …

One of the most recent advances in knee replacement surgery is the Unicompartmental
Knee Prosthesis that involves the substitution of only one compartment. Uncertainties on the …
