Performance of medial pivot, posterior stabilized and rotating platform total knee arthroplasty based on anteroposterior stability and patient-reported outcome measures; a multicentre double-blinded randomized controlled trial of 210 knees.

Background: Despite advancements in total knee arthroplasty (TKA), 10-20% of patients remain dissatisfied after surgery. Improved anteroposterior (AP) stability provided by medial pivot (MP) implants may theoretically lead to higher patient satisfaction.

Methods: AP stability and patient-reported outcome measures (PROMs) at one-year postsurgery were compared between patients who underwent TKA with MP- (n = 121), posterior stabilized (PS; n = 53) and rotating platform (RP; n = 57) implants in a double-blind multicentre randomized controlled trial (Dutch Trial Register: NL6856, 21-02-2018).

Major obstetric hemorrhage: a follow-up survey on quality of life of women and their partners.

Introduction: A description is given of the quality of life (QOL) of women who were treated with peripartum embolization or hysterectomy for major obstetric hemorrhage (MOH).

Methods: Questionnaires assessing QOL, combined with questionnaires and drawings assessing illness perceptions, were used to compare women with MOH to reference groups provided by the questionnaires.

Results: Women who experienced MOH have similar scores on QOL questionnaires compared to reference groups.

Increasing incidence of postpartum hemorrhage: the Dutch piece of the puzzle.

Introduction: An increase of postpartum hemorrhage (PPH) has been reported in many high-income countries. In addition to this data, this study reports on trends in the incidence of PPH in the Netherlands in 2000-2013, and examines the extent to which temporal changes in risk indicators could explain a possible change in incidence of PPH.

Material And Methods: We used data from the Dutch Perinatal Registry, which contains prospectively collected antenatal, peripartum and neonatal data of 95-99% of all women and neonates in the Netherlands.

Do tibiofemoral contact point and posterior condylar offset influence outcome and range of motion in a mobile-bearing total knee arthroplasty?

Purpose: The posterior condylar offset (PCO) and the tibiofemoral contact point (CP) have been reported as important factors that can influence range of motion and clinical outcome after total knee arthroplasty. A mobile-bearing knee implant with an anterior posterior gliding insert would in theory be more sensitive for changes in PCO and CP. For this reason, we analysed the PCO and CP and the relation with outcome and range of motion in 132 patients from a prospectively documented cohort in this type of implant.
