Ultrasonic evaluation of plantar fascia in patients with osteoarthritis of the knee

To study the changes of plantar fascia in patients with knee osteoarthritis. Collect knee arthritis surgery patients and according to the length of the course is divided into long-course and short-course group, collection of healthy volunteers as control group at the same time, basic information such as age, height, weight, and body mass index (BMI) were recorded; the application of Philips and Siemens ultrasonic diagnostic instrument, a foot plantar fascia in patients with knee osteoarthritis in ultrasonic scanning, measuring the thickness of the heel of plantar fascia, observe its sonographic manifestation; age, BMI, and plantar fascia thickness were compared between groups. The plantar fascia thickness of the normal control group was 0.30 +/- 0.06 cm on the left side and 0.30 +/- 0.05 cm on the right side. The plantar fascia thickness of the long-course group was 0.44 +/- 0.10 cm on the left side and 0.42 +/- 0.10 cm on the right side. The plantar fascia thickness of the group with short course of disease was 0.37 +/- 0.06 cm on the left side and 0.34 +/- 0.7 cm on the right side. Multivariable analysis of variance was used to compare the thickness of plantar fascia in the long-course group, the short-course group, and the control group, P < .05; there were statistical differences among the 3 groups. Multivariate analysis of variance was used to compare the general data of the long-course group, the short-course group, and the control group. Age: the long-course group was compared with the short-course group and the control group, P < .05; short-course group compared with control group, P > .05. BMI: compared with long-course group and short-course group, P < .05; long course of disease group compared with short course of disease group, P > .05. BMI was statistically different between the case group and the control group. Plantar fascia was thickened in patients with knee osteoarthritis, and the thickening of plantar fascia was related to BMI. The thickening of plantar fascia was uneven, and the degree of thickening was related to the course of disease. At the same time, the sonogram of plantar fascia was less echogenic than that of normal controls.
