Association Between Years of Experience and Ankle Joint Disorder in Male Student Basketball Players Based on Ultrasonography

Abstract

Purpose: The goal of the study was to survey ankle joint disorder in male senior high school and college student basketball players based on the results of an ultrasonographic medical check-up of the ankle joint.

Materials and methods: The subjects were 17 senior high school student and 19 college student basketball players. Ultrasonography, evaluation of ATFL injury, and examination of the talocrural joint region were performed. The subjects were grouped based on the presence or absence of old ATFL injury, and subjects with ATFL injury were classified by the injured region: fibular insertion site, parenchyma, and talar insertion site. The talocrural joint region was evaluated based on the areas of the lateral margin, central region, and medial margin, and sites with an irregular bone contour and osteophyte were counted individually. The questionnaire asked about the patients' history of ankle injuries.

Results: A questionnaire survey revealed that 70-79% of all subjects had experienced a sprain at least once and 21-29% had frequently sprained the left or right foot 10 or more times in the past. On ultrasonography, there was no significant difference in ligament injury or injured site between the senior high school and college students, but the number of osteochondral findings in the talocrural joint region was significantly higher in the college students. In addition, the number of injured sites significantly increased in those with 10 or more years of playing experience.

Conclusion: These results suggest that disorder of the talocrural joint region progresses with an increase in years of experience in student basketball players who do not take specific preventive measures against this injury.

a Healthy ankle group The healthy ankle group (grades 0: no injury and 1: elongation without tear and swelling without tear) has no old tears of the ATFL. b Injured ankle group The injured ankle group (grade 2: partial tear and grade 3: compete tear) has an old tear of the ATFL.

Years of basketball experience in all subjects 16 of the 19 college students had experience of ≥10 years. Therefore, we divided the subjects into 2 groups: one group with 10 or more years of experience and one group with less than 10 years of experience.
