DOI: 10.1002/srin.202000241
Abstract: Bearing steels can be exposed to extreme service environments such as high contact pressure, high rotational speed, and/or elevated temperatures. Rolling contact fatigue (RCF) is therefore a key factor affecting the bearings life. Many authors… read more here.

DOI: 10.1007/s00167-017-4542-6
Abstract: PurposeOnly few long-term data on ligament-balanced cruciate-retaining total knee arthroplasty (CR TKA) are currently available. Either a mobile- or fixed-bearing insert can be chosen, which showed good mid-term outcome and few complications and revisions. This… read more here.
