MSC Physiotherapy - Tendons and Ligaments

Primary, Secondary and Tertiary bundles are surrounded by a sheath that facilitates gliding of bundles against each other during movement. What is the name of this sheath?

• Endotendon

• Fasicles

• Collagen Type II

• Paratenon

Approximately how much of the cellular component of a tendon is made up of Tenoblasts and Tenocytes?

• 20-25%

• 90-95%

• 80%

• 70%

The tendon ECM is comprised mainly of Collagen Type 3 and minimal amounts of Collagen Type 1, proteoglycans and glycosaminoglycans

• True

• False

What is the function of Collagen Crimps?

• • Provide extensibility and flexibility, permit long range deformability and passive recoil without energy input.

• Provide increased strength within the tendon

• They are the powerhouse of the cell

• Increase stiffness of the tendon, decrease flexibility and increase energy input

What are the 2 main functions types of Tendons?

• Positional and Energy Storage

• Stability and Positional

• Energy Storage and Strength

• Strength and Stability

Deep Ligament Fibres insert directly into bone via what?

• Cartilage
• Muscles
• Tendons
• Sharpey's fibers

Elongation of ligaments under constant or cyclic repetition is know as what?

• Strain

• Proprioception

• Creep

• Elastic Recoil

Ligaments have a higher percentage of Collagen Type III than Tendons

• True

• False

At what stage of Tendon Tissue Healing do the Tenocytes and Collagen Fibres begin to align in the direction of stress to restore strength and tendon stiffness?

• Maturation

• Consolidation

• Proliferation

• Inflammation

Roughly how long does the final maturation stage of tendon tissue healing take?

• 6-8 weeks

• 6-12 months

• 1-2 years

• 3-5 years
