Table 3:

Specific ultrasound findings for all tendons (right and left Achilles and patellar tendons, n = 552 tendons [138 runners]), and development of pain over the following year. Values represented as n (%), where n refers to the number of tendons with that particular abnormality, and the percentage relates to the proportion of that particular tendon abnormality that did or did not develop pain.

Achilles	Develop pain	12 (38.7%)	2 (40%)	1 (16.7%)	1 (14.3%)	11 (50%)
	Do not develop	19 (61.3%)	3 (60%)	6 (83.3%)	6 (85.7%)	11 (50%)
Patellar	Develop pain	8 (16.7%)	0 (0%)	8 (28.6%)	4 (26.7%)	7 (17.5%)
	Do not develop	40 (83.3%)	1 (100%)	20 (71.4%)	11 (73.3%)	33 (82.5%)
