Open AccessInfluence of bone density on morphologic cement penetration in minimally invasive tibial unicompartmental knee arthroplasty: an in vitro cadaver study
Unicompartmental knee arthroplasty is an established treatment option for anteromedial osteoarthritis. However, large registry studies report higher rates of aseptic loosening compared to total knee arthroplas...

TKA design-integrated trochlea groove rotation reduces patellofemoral pressure
Total knee arthroplasty (TKA) leaves 11–25% of the patients unsatisfied, and patellofemoral joint pain is one cause. This study aimed to compare the differences between kinematics and load transfer in the same...

Open AccessAccuracy of a non-invasive CT-based measuring technique for cement penetration depth in human tibial UKA
Aseptic loosening of the tibial component remains a major cause of failure in unicompartmental knee arthroplasty (UKA) and may be related to micro-motion at the cement-bone interface due to insufficient cement...
