Right Breast Capsulated After 20 Years - Why?

This is really a hard question to answer.  However, the reason why they did is less critical than the fact that encapsulation is actually relatively straightforward to correct.  Most PS's will simply remove some or all of the hardened capsule, wash the pocket out extensively with antibiotic solution, and then replace both implants.  By doing so, the results can often be quite pleasing and the downtime is next to nothing.

I hope that helps!

Schedule a consultation with a board certified PS and plan to have the implants replaced.  The cause of CC is unknown but if your implants are giving you problems, it is time to change them.

Many times, the exact reason that capsular contracture occurs is never known.

If there was bleeding or infection recently in the breast, this could be a cause.

If your implant has ruptured, this could also be a cause.

I'd recommend getting an ultrasound to check on your implant.  If the capsule is hard, painful or looks asymmetric, those are all reasons to consider the corrective surgery.  Your local board-certified plastic surgeon can help you with this.
