Value of digital telethermography for the diagnosis of septic knee prosthesis: a prospective cohort study / C.L. Romanò, R. D'Anchise, M. Calamita, G. Manzi, D. Romanò, V. Sansone. - In: BMC MUSCULOSKELETAL DISORDERS. - ISSN 1471-2474. - 14(2013), pp. 7.1-7.7.
Abstract:
BAckground. Diagnosis of peri-prosthetic infection remains challenging, often requiring a combination of different tests.
METHODS:
In this prospective, case-control study, the diagnostic accuracy of telethermography was evaluated in a group of seventy patients who had had a total knee replacement and were undergoing a reoperation because of infection or another implant-related problem, after a minimum of one year from implant.
RESULTS:
An average differential temperature of the affected versus not affected knee of 1.9 °C was observed in infected prosthesis, compared to 0.3 °C in aseptic failures. Considering a normal reference value equal or less than 1.0 °C, telethermography showed an accuracy, sensitivity, specificity, positive and negative predictive value of, respectively: 0.90, 0.89, 0.91, 0.91, 0.88.
CONCLUSIONS:
Digital telethermography is a reliable option for diagnosing peri-prosthetic knee infection.
