How It Works Flashcards
What does a tear in the cuff mean for the rest of the tendon?
More force going through a smaller surface area
Increasing tendon thickness decreases what in tendon?
What does this create?
Decreases the stress and strains put through the tendon.
Creates favorable healing environment that allows the tendon to heal itself over time
What are two characteristics of unorganized scar tissue compared with healthy tendon tissue?
- Weaker
- Thicker
Healthy aligned tendon tissue leads to less of what?
Less stress going through tendon
What is the problem with grafts that have strength?
Nothing can grow through these grafts which causes scar tissue
What do fibroblasts do with type 1 collagen?
Remodel it and form new tendon like tissue
What does the type 1 collagen prevent fibroblasts from making?
Scar tissue
Why don’t PTTs heal?
Too much stress on smaller surface area of remaining healthy part of tendon
Why do partial thickness tears progress?
Too much stress on remaining tendon
Regeneten decreases what on underside of tendon which allows a favorable healing environment
Peak stresses and strains
Computer analysis on Regeneten shows what?
2mm increase of tendon on bursal sides decreases peak stresses and strains by 40% on articular side
What is angiogenesis?
Formation and growth of new blood vessels into the implant
