Six hundred and ninety consecutive MRI images obtained on 1.5 T or 3.0 T devices were reviewed to investigate the prevalence and diagnostic pitfalls of the vacuum phenomenon (VP) of the knee joint. The VP was identified on 13 knees and 7 knees (53.8%) were diagnosed with osteoarthritis. Gradient-echo imaging facilitated the delineation of minute VP within the joint space with susceptibility artifacts.
