Comparison operative and conservative management for primary patellar dislocation: an up-to-date meta-analysis.

Purpose: The aim of this review was to compare the clinical outcomes between operative and conservative management for primary patella dislocation (PPD).

Methods: PubMed Medline, EMBASE, Google scholar, and the Cochrane Library were systematically searched for randomized controlled trials that compared operative technique versus conservative technique for PPD. The results of eligible studies were independently extracted and analyzed according to the following: patient's satisfaction, Kujala score, Tegner score, and redislocation rate.

A novel, solventless reductive coupling of carbonyl compounds by alkali metals, catalysed by bromobenzene.

Catalysed by bromobenzene, alkali metals including Li, Na, and K can mediate the reductive coupling of carbonyl compounds under mild, solventless conditions to furnish the corresponding pinacol products.
