Research on the Examination Value of High-Frequency Ultrasound in the Postoperative Rehabilitation Treatment of Sports Injury Achilles Tendon Rupture

The objective of the paper is to explore the examination value of high-frequency ultrasonography in the postoperative rehabilitation treatment of Achilles tendon injury occurred during sports events. The high-frequency ultrasound imaging technique was applied to examine the Achilles
 tendon injuries of patients. After the patients accepted Achilles tendon rupture repair surgeries, ultrasound imaging was applied to detect the rehabilitation conditions during the recovery processes. The diagnosis was mainly performed through the Achilles tendon sonograms examined 4 weeks,
 6 weeks, 12 weeks, 24 weeks after the surgeries respectively; in addition, the changes in the American Orthopedic Foot and Ankle Score (AOFAS) and the elasticity modulus of repaired Achilles tendons were observed 8 weeks, 12 weeks, 24 weeks, and 48 weeks after the surgeries respectively. The
 results showed that the Achilles tendon was significantly improved after the postoperative rehabilitation, and the average AOFAS score was positively correlated with the elasticity modulus of the repaired Achilles tendon. In addition, the research results also indicated that the high-frequency
 ultrasound technology could accurately observe the thickness, area, and internal echo of the Achilles tendons of patients dynamically in real-time, which was convenient and quick. After the patient had undergone rehabilitation training, high-frequency ultrasound could be used to detect the
 postoperative rehabilitation conditions of patients, thereby the real-time rehabilitation conditions of the patients would be obtained.
