From: The vasculature and its role in the damaged and healing tendon
Condition | Observations |
---|---|
Tendon grafts | Neovascularisation is essential for long term survival of graft Potential model for study of neovascularisation in tendon injury and pathology |
Acute injury | Lack of knowledge of timing and control of the vascular response Increased vascularity at tendon stump following resection Initial vascular response is profuse and haphazard Diminution of blood supply results in impairment of repair process |
Chronic tendinopathy | Increased vascularity is associated with chronic (painful) tendon lesions Hypervascularity is apparently not associated with signs of attempted repair Hypervascularity may be a contributory factor to pain and chronicity of tendon lesions |
Spontaneous tendon rupture | Degeneration occurs before rupture without preceding clinical symptoms There is usually no evidence of a vascular response Absence of blood vessels is responsible for absence of pain and symptoms |
