The aim of this review article is to analyze the clinical effectiveness of total knee replacement (TKR) compared to unicompartmental knee replacement (UKR) in patients with medial unicompartmental osteoarthritis (MUO) in terms of survival rates, revision rates and postoperative complications. The search engine was MedLine. The keywords used were: medial knee osteoarthritis. Three thousand and n...

In this paper, we propose a revision-based approach for conflict resolution by generalizing the Disjunctive Maxi-Adjustment (DMA) approach (Benferhat et al. 2004). Revision operators can be classified into two different families: the model-based ones and the formula-based ones.

Background: Cementless total hip replacement is the common THR performed in England, Wales, Northern Irelandand the Isle of Man. The Corail stem is the most popular cementless implant and has a ODEP 10A rating. Review ofits performance in the registry identified an increase rate of revision amongst the smaller stem sizes. However, claritywas not provided on the explanation for this finding. We ...

We show that the Darwiche-Pearl arguments lead naturally to the acceptance of a smaller class of operators which we refer to as admissible. These a...
