Quantifying Patellar Tendon Microstructure Using DTI
Quantifying Patellar Tendon Microstructure Using Diffusion Tensor Imaging
The goal of this observational study is to understand how diffusion tensor imaging (DTI) relates to other traditional measures and knee function. The main question it aims to answer is:
Will regions of known patellar tendon pathology present with smaller DTI scalar parameters, shorter fiber length, and lower fiber density compared to the contralateral tendon and healthy regions in the ipsilateral tendon.
Participants will:
- undergo MRI and ultrasound imaging
- perform knee function test
- complete questionnaires

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Bone-patellar tendon-bone (BPTB)
This group will have patellar injury confirmed through self-reported surgical history and evidence of ipsilateral BPTB graft harvest on ultrasound.
|
MRI using DTI technology
Standard US
|
Patellar tendinopathy group
This group will have patellar tendinopathy confirmed based on International Scientific Tendinopathy Symposium Consensus on Clinical Terminology (ICON) statement, which defines patellar tendinopathy as "persistent patellar tendon pain and loss of function related to mechanical loading."
Ultrasound diagnosis must confirm alteration of tendon macrostructure.

Measure Description |
Time Frame |
---|---|---|
Compare scalar parameters of known patellar tendon pathology to the contralateral tendon
Time Frame: Up to 2 weeks
|
DTI parameters will be obtained by built-in diffusion-weighted sequences on the GE MRI machine.
Regions of interest will be selected using clinical scans, and region specific DTI parameters will be compared between regions and over the repeat test sessions
|
Up to 2 weeks
