Risk assessment of the onset of Osgood-Schlatter disease using kinetic analysis of various motions in sports.
Ontology highlight
ABSTRACT: Some studies have listed motions that may cause Osgood-Schlatter disease, but none have quantitatively assessed the load on the tibial tubercle by such motions.To quantitatively identify the load on the tibial tubercle through a biomechanical approach using various motions that may cause Osgood-Schlatter disease, and to compare the load between different motions.Eight healthy male subjects were included. They conducted 4 types of kicks with a soccer ball, 2 types of runs, 2 types of squats, 2 types of jump landings, 2 types of stops, 1 type of turn, and 1 type of cutting motion. The angular impulse was calculated for knee extension moments ?1.0 Nm/kg, ?1.5 Nm/kg, ?2.0 Nm/kg, and ?2.5 Nm/kg. After analysis of variance, the post-hoc test was used to perform pairwise comparisons between all groups.The motion with the highest mean angular impulse of knee extension moment ?1.0 Nm/kg was the single-leg landing after a jump, and that with the second highest mean was the cutting motion. At ?1.5 Nm/kg, ?2.0 Nm/kg, and ?2.5 Nm/kg, the cutting motion was the highest, followed by the jump with a single-leg landing. They have a large load, and are associated with a higher risk of developing Osgood-Schlatter disease. The mean angular impulse of the 2 types of runs was small at all the indicators.Motions with a high risk of developing Osgood-Schlatter disease and low-risk motions can be assessed in further detail if future studies can quantify the load and number of repetitions that may cause Osgood-Schlatter disease while considering age and the development stage. Scheduled training regimens that balance load on the tibial tubercle with low-load motions after a training day of many load-intensive motions may prevent athletes from developing Osgood-Schlatter disease and increase their participation in sports.
