What happens to the scar tissue within Achilles tendonitis? Is it forever a weak spot?

Have it treated. Tears in the achilles or chronic inflammation can result in scarring, which is not as oriented or as strong as the natural tendon. Many are using fat-derived stem/stromal cells plus platelet-rich plasma to be placed (via guided ultrasound) within the shealth of the tendon. New tendon often results which is stronger and flexible like original tendon tissues.
Yes. Scar is always weaker than uninjured tissue but the difference is often not functionally significant. The achilles tendon is one area that is subject to the greatest torque and shear forces by virtue of the weight carried in this area which makes it particularly more vulnerable to repetitive trauma.
Depends. It depends on the amount of soft tissue destruction. If the inflammation is controlled, soft tissue destruction and scarring should be minimized.

Could you tell me what happens to the scar tissue within Achilles tendonitis?

Ineffective healing. When scar builds up in a torn or ruptured tendon, it is often not quality strength and will reinjure easily. The body tried to heal the tendon, but microtraumas continue to happen, cause inflammation and scar not lined up in the long axis of the tendon. Best treatments are often use of undifferentiated cells plus platelet concentrates injected into the tendon to heal with tendon, not scarring. Read more...
Stretches and weaken. Normally, scar tissue is the important part of healing of mesenchymal tissues.As the scar tissue forms as a result of trauma(imicrohemorhage), or inflammation the tensile strength diminishes.Eventually the tendon may rupture.Scar tissue collagen is quite different from the collagen of the normal tendon.In scar they are arranged in disorderly fashion incontrast the collagen in tendoachilis is arrange.

Remodels. Tendinitis or inflammation of a tendon results in swelling of the adjacent tissues that are rubbed by the inflamed tendon. The tendon often develops swollen areas that are tender as well. These improve after the irritation is reduced by splinting or medication. Read more...

Is there scar tissue associated with Achilles tendonitis?

Possibly yes. Signs of inflammation such as swelling, warmth, and pain occur in a person with achilles' tendonitis. Damaged tendons can become calcified (get deposits of calcium), thicker than normal, less elastic (not as stretchable), and fibrotic (form scar tissue fibers). Tendon rupture occurs when a sudden shear stress force is applied to an already inflamed or damaged tendon. Read more...
Depends. Is really depends. There is a gradation of issues with the tendon from simple tendonitis/inflammation to tendinosis/degeneration. The tendonitis can improve with little to no scar tissue. The tendinosis is less likely to do so. Read more...
