NCT07470671

Brief Summary

In current literature, databases of healthy knee anatomy and function are confined to small sample sizes or singular imaging modalities. In this study, the investigator propose constructing a unique and large-scale database of healthy Caucasian knee anatomy and function by utilizing a combination of ultra-high resolution capabilities from photon-counting CT, lower limb weightbearing orthogonal imaging (EOS) of full leg, and non-invasive ultrasound-based functional testing of the knee. This study is a collaborative effort between the orthopaedics, radiology and biomechanical engineering departments in which the same prospectively acquired database will be used for multiple independent research questions.

Outcome Measures

Primary Outcomes (3)

  • CT scan

    CT scan images of the knee allow for detailed anatomical analysis of joint shape through the means of statistical shape modelling (SSM).

    Day 1

  • EOS scan

    EOS imaging of the full leg

    Day 1

  • Ultrasound

    Ultrasound-based gap analysis is a non-invasive and previously validated method of determining medio-lateral laxity of the knee joint.

    Day 1

Secondary Outcomes (1)

  • International Physical Activity Questionnaire

    Day 1

Study Arms (1)

Healthy Caucasian knees

Healthy Caucasian volunteers aged from 20 till 35 years old

Interventions

CT scan images of the knee allow for detailed anatomical analysis of joint shape through the means of statistical shape modelling.

Healthy Caucasian knees

Software-based reconstruction of orthogonal images provided by EOS imaging allows for a comprehensive three-dimensional analysis of lower limb alignment without the need for a full leg CT scan, minimizing exposure to ionizing radiation in the pelvic region.

Healthy Caucasian knees

For the analysis of constitutional balance, this study will use an ultrasound-based technique. This is a non-invasive and previously validated method of determining medio-lateral laxity of the knee joint.

Eligibility Criteria

Age20 Years - 35 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Aged 20-35 years old.
  • 'Caucasian':
  • Self-identification as Caucasian or of European descent.
  • Self-identification as having 'fair' skin tone.
  • Both parents and all grandparents are of Caucasian or European descent.
  • Healthy knee and lower limb:
  • No bony orthopaedic or trauma history in the lower limb (pelvis - foot).
  • No ligamentary or soft tissue trauma history in the knee.
  • No ligamentary or soft tissue trauma in the lower limb requiring cast immobilization.

You may not qualify if:

  • Participant uncertainty of pregnancy status.
  • Open wounds over the knee joint.
