A New Test for Achilles Tendinopathy Based on Kager’s Fat Pad Clinical Assessment Predictive Values Rodríguez Sanz, David Losa Iglesias, Marta Elena Becerro De Bengoa Vallejo, Ricardo Sánchez Milá, Zacarías Dorgham, Hend Adel Abdelhalim Elerian, Ahmed Ebrahim Yu, Tian Calvo Lobo, César Velázquez Saornil, Jorge Martínez Jiménez, Eva María Background This study aimed to check the diagnostic accuracy of a new test to identify Achilles tendinopathy. Study Design: Observational study. Methods: Seventy patients recruited from a private medical centre met the diagnostic criteria for unilateral Achilles tendinopathy (age, 45.1 ± 12.7 years; weight, 75.00 ± 10 kg; height, 1.75 ± 0.1 m) and were tested based on both Achilles tendons. Seventy patients with a unilateral Achilles tendinopathy ultrasound diagnosis were tested using David’s test. Results: Most (86%) subjects demonstrated Kager’s fat pad asymmetry in relation to the Achilles tendon in the complete passive dorsiflexion in the prone position (David’s sign). No healthy tendons had David’s sign. Conclusions: The presence of asymmetry in Kager’s fat pad in relation to the Achilles tendon during complete passive dorsiflexion is strongly indicative of ultrasound-diagnosed tendinopathy. David’s test demonstrated a sensitivity of 85.71% (95% CI, 77.51% to 93.91%) and a specificity of 100% (95% CI, 100% to 100%), while noting the lack of blinding of the assessors and the uncertainty of the diagnostic measures (95% CI). Asymmetry of the fat pad could potentially serve as a characteristic marker for patients with Achilles tendinopathy. 2025-10-03T14:58:35Z 2025-10-03T14:58:35Z 2025-10-03T14:58:35Z 2023-08-09 journal article https://hdl.handle.net/20.500.14352/124506 2077-0383 10.3390/jcm12165183 2077-0383 eng Rodríguez-Sanz D, Losa-Iglesias ME, de Bengoa-Vallejo RB, Sánchez-Milá Z, Dorgham HAA, Elerian AE, et al.
