“…Demographic information (see File 1, Supplemental Digital Content, http://links.lww.com/JSM/ A387) was obtained through self-reported survey at the time of ultrasound scans. All student-athletes were eligible with the following exclusion criteria: (1) age younger than 18 years or (2) prior surgery/amputation to structures (including ACL surgeries with patellar tendon grafts; only the affected tendon/fascia was excluded in the statistical analysis). The sonographic scans were performed in a protocolized fashion with a 12 to 18 MHz linear probe (Logiq E9 R7, Sonosite PX, Sonosite X-porte, Konica Minolta Sonimage HS-1).…”

“…Patellar tendinopathy, Achilles tendinopathy, and plantar fasciopathy are common conditions that prevent athletes from participating in practice and competition. [1][2][3] These conditions can be challenging to treat and can lead to time-intensive and costly interventions. Ultrasound is a cost-effective and accessible diagnostic tool for these 3 conditions.…”

Objective: This study aimed to determine the prevalence of ultrasound abnormalities in the Achilles tendon, patellar tendon, and plantar fascia among a large cohort of collegiate student-athletes. Design: Observational cross-sectional study. Setting: Three Division I institutions. Participants: 243 student-athletes participated in this study. Exclusion criteria included those younger than 18 years or who underwent prior surgery/amputation of structures, including anterior cruciate ligament (ACL) surgeries with patellar tendon grafts. Interventions: Ultrasound examination of the Achilles tendon, patellar tendon, and plantar fascia of each leg was performed. An experienced sonographer reviewed each tendon video in a blinded manner, with a separate experienced sonographer separately reviewing to establish inter-rater reliability. Main Outcome Measures: The primary outcome measured was the presence of any sonographic abnormality including hypoechogenicity, thickening, or neovascularity. Results: Ultrasound abnormalities were identified in 10.1%, 37.2%, and 3.9% of all Achilles tendons, patellar tendons, and plantar fasciae, respectively. Abnormalities were significantly associated with the presence of concurrent pain for all structures (P < 0.01). Specifically, athletes with sonographic abnormalities were approximately 4 times [relative risk (RR) = 4.25; 95% confidence interval (CI), 2.05-8.84], 6 times (RR = 5.69; 95% CI, 2.31-14.00), and 5 times (RR = 5.17; 95% CI, 1.76-15.25) more likely to self-report pain in the Achilles tendon, patellar tendon, and plantar fascia, respectively. Conclusions: This multi-institutional study completed at 3 Division I institutions is the largest study of its kind to identify the prevalence of sonographic abnormalities in the Achilles tendon, patellar tendon, and plantar fascia among collegiate student-athletes of various sports.

This study aimed to assess the longitudinal changes in triceps surae muscle-tendon architecture to an mountain ultramarathon. Experienced trail runners (N=55, 78% men, age: 45.2 [13.5] years) participated in a 156-km trail run (6000m climbing) consisting in six 26-km laps. The resting architectural properties of triceps surae muscle-tendon were measured using ultrasound imaging for Achilles tendon cross-sectional area (AT CSA), medial gastrocnemius muscle pennation angle, thickness, length and fiber length. Measurements were performed the day before the race (Baseline), at 52-km (T1), at 104-km (T2), at 156-km (T3) and 12 hours after the race (H12). Among finishers (n=41), there was a significant biphasic change in AT CSA during the race (P = 0.001). Firstly, a significant decrease in AT CSA occurred between Baseline and T1 (P = 0.006), with greater decrease for participants averaging speed >8 km/h (p = 0.014). Secondary, there was a significant increase in AT CSA especially between T2 and T3 (P = 0.006) that was correlated with a decrease in average speed (P = 0.001) and alteration of spaciotemporal running parameters (p < 0.05). Changes in muscle-tendon architecture was not significantly different between finishers (n=41) and non-finishers (n=14). In 47 participants (85.5%) who completed the follow-up, AT CSA at H12 was greater compared to Baseline (P = 0.010). The main finding is the significant and biphasic modification of the AT CSA during a 156-km mountain ultramarathon with an initial decrease corresponding to mechanical stress followed by a secondary increase suggesting adaptive mechanotransduction persisting after 12 hours.
