Fig. 4From: Age-related changes in mechanical properties of semitendinosus tendon used for anterior cruciate ligament reconstructionRelationship between the extent of slackening of the semitendinosus tendon specimen and patient age. The extent of slackening was calculated based on the initial length of the 1st (A) or 6th cycle (B). The extent of slackening from both the 1st and 6th cycles was not significantly correlated with patient ageBack to article page
