Table 4. Comparisons of the shear elastic modulus, thickness and CSA of the patellar tendon on the painful side of athletes with unilateral PT and dominant side of the healthy athletes.

Variables	Control group	PT group	P Value
	(n = 20)	(n = 13)
Shear elastic modulus, kPa	27.5±11.3	43.6±17.9	0.003*
Thickness, mm	5.6±1.2	6.9±1.8	0.019*
CSA, cm2	1.4±0.3	1.7±0.4	0.032*

Values shown as mean ± standard deviation; PT =  patellar tendinopathy; CSA =  cross sectional area.*P<0.05.
