|
Tendons connect what two structures?
|
Muscle
Bone |
|
|
What is the four-part sequence of transitional tissue as tendon attaches to bone?
|
Tendon
Fibrocartilage Mineralized fibrocartilage (Sharpey’s fibers) Bone |
|
|
Describe the toe region of the tendon stress-strain curve? Why?
|
Small toe region ("tendons have tiny toes")
Because of high collagen content within tendons (85% collagen) |
|
|
Paratenon covered tendons vs.sheathed tendons: which heal more better readily and why?
|
Paratenon covered tendons heal better
Because they have a rich capillary system that provides excellent vascularity |
|
|
When reinserting tendon to bone, is there a proven benefit to creating a bony trough?
|
No demonstrated benefit
|
|
|
What is the advantage of early active motion after tendon injury?
|
Improved ROM relative to immobilization
|
|
|
What is the disadvantage of early active motion?
|
Stresses repair and healing tissue
|
|
|
What is the preferred form of motion after tendon repair?
|
Controlled passive motion
|
|
|
What three microscopic changes are seen in tendon composition after prolonged immobilization?
|
Decreased collagen diameter
Increased collagen disorder Decreased cellularity |
|
|
What effect do these changes have on tendon strength?
|
Reduced
