In-office needle-based diagnostic imaging appears to be statistically equivalent to surgical diagnostic arthroscopy in patients with knee pain, according to an article published online in Arthroscopy. 

The prospective, blinded, multicenter trial included 110 consecutive patients aged 18–75 years who presented with knee pain between April 2012 and April 2013. Each patient underwent a physical examination, MRI, in-office diagnostic imaging, and a diagnostic arthroscopic examination in the operating room. Two blinded, unaffiliated experts reviewed the in-office arthroscopic images and MRI images using the surgical diagnostic arthroscopy images as the “control” group. The accuracy, sensitivity, and specificity of in-office arthroscopy was equivalent to surgical diagnostic arthroscopy and more accurate than MRI. There were no patient- or device-related complications with in-office arthroscopy. Read the abstract...
