Design
The present study was a cross-sectional prospective study that was approved by the Helsinki Committee of our medical center. Each subject received an explanation about the aim of the study and the methods of data collection. Only after providing written informed consent were the subjects included in the present study.
Participants
Ninety-three participants were evaluated in a single session examination. Of the 93 subjects, 63 had a diagnosis of symptomatic unilateral or bilateral knee OA of ≥3 months
Study Flow
The present study included 63 subjects (41 [65.1%] females and 22 [34.9%] males) with unilateral or bilateral knee OA (medial tibiofemoral compartment) and 30 asymptomatic controls (9 [30%] females and 21 [70%] males). The mean age was 64.2 ± 8.1 years and 67.9 ± 8.9 years for the patients with knee OA and healthy controls, respectively, and this difference was not statistically significant (p = .063). No drop-outs occurred because all the data were collected at 1 session. Recruitment was
Discussion
The purpose of the present study was to evaluate the association between knee OA and Achilles tendon pathology. The results of our study confirmed our first hypothesis that patients with knee OA will have a thicker Achilles tendon compared with healthy controls. Our second hypothesis that the Achilles tendon thickness would correlate with knee OA severity, measured using different variables, was also confirmed.
Subjects with knee OA had a significantly thicker Achilles tendon compared with
