Detection of osteoarthritis using acoustic emission analysis

Previous studies indicated that Acoustic Emission Analysis (AEA) can detect osteoarthritis OA earlier than other techniques [1 –4]. In principle, AEA measures acoustic emissions (AE) produced by any material under load or strain. Lesions, e.g., in cartilage, lead to characteristical alterations in the AE during load [1–5]. These emissions can be detected and interpreted for diagnosis. AEA has the potential for the early diagnosis of OA, e.g., at stages, when cartilage regeneration is still possible [6–9], but the assessment of the diagnostic accuracy of AEA is necessary.
