Abstract
This study was performed to investigate the value of knee thermography as a screening procedure in an attempt to decrease the number of negative arthrograms. Thermagraphy was performed on 90 consecutive patients prior to double contrast knee arthrography. Most of these patients were examined for evaluation of the menisci. Surgical follow-up was available in 39 patients. Clinical follow-up was available in 46; five patients were lost to follow-up. Fifteen patients (18%) has normal thcrmograms and positive arthrograms. On the basis of this study, we feel that this high percentage of false negatives precludes the use of thermegraphy as an accurate screening procedure in the diagnosis of internal derangements of the knee.
