Does interval time between pulsed dye laser treatments for port-wine stains influence outcome? A systematic review and meta-analysis.

The pulsed dye laser (PDL) is the standard treatment for port-wine stains (PWS). Maximal improvement occurs after multiple treatment sessions; however, the optimal treatment interval has yet to be determined. The aim of this study was to review whether there is an association between PDL treatment interval and outcome of PWS.

The medial border of the tibial tuberosity as an auxiliary tool for tibial component rotational alignment during total knee arthroplasty (TKA).

Purpose: The objective of this study was to quantify the amount of ensuing internal rotation of the tibial component when positioned along the medial border of the tibial tubercle, thus establishing a reproducible intraoperative reference for tibial component rotational alignment during total knee arthroplasty (TKA).

Methods: The angle formed from the tibial geometric centre to the intersection of both lines from the middle of the tibial tuberosity and its medial border was measured in 50 patients. The geometric centre was determined on an axial CT slice at 10 mm below the lateral tibial plateau and transposed to a slice at the level of the most prominent part of the tibial tuberosity.
