Fig 1.
Ultrasound assessment and measurement of the patellar tendon.
(A) the linear transducer placed longitudinally distal to the patella, (B) thickness of the PT was assessed at four locations: 5, 10, 15, and 20 mm inferior to the apex of the patella, (C) the 3D graphical representation of PT thickness at each location (5-10-15-20 mm).
Table 1.
Ultrasound measurements for PT thickness (mm) at the four measurement points (5-10-15-20mm).
Table 2.
Intra-class correlation coefficients (ICC), 95% confidence Interval (95% CI), standard error of measurement (SEM), minimal detectable change (MDC) and 95% limit of agreement (LOA) for intra- and inter-rater reliability of patellar tendon thickness.
