Despite the fact that research fraud and misconduct are under scrutiny in the field of orthopaedic research, little systematic work has been done to uncover and characterise the underlying reasons for academic retractions in this field. The purpose of this study was to determine the rate of retractions and identify the reasons for retracted publications in the orthopaedic literature. Two reviewers independently searched MEDLINE, EMBASE, and the Cochrane Library (1995 to current) using MeSH keyword headings and the ‘retracted’ filter. We also searched an independent website that reports and archives retracted scientific publications (Objectives
Methods
To study the effect of hyaluronic acid (HA) on local anaesthetic
chondrotoxicity Chondrocytes were harvested from bovine femoral condyle cartilage
and isolated using collagenase-containing media. At 24 hours after
seeding 15 000 cells per well onto a 96-well plate, chondrocytes
were treated with media (DMEM/F12 + ITS), PBS, 1:1 lidocaine (2%):PBS,
1:1 bupivacaine (0.5%):PBS, 1:1 lidocaine (2%):HA, 1:1 bupivacaine (0.
5%):HA, or 1:1 HA:PBS for one hour. Following treatment, groups
had conditions removed and 24-hour incubation. Cell viability was
assessed using PrestoBlue and confirmed visually using fluorescence
microscopy.Objective
