I worry less about capsular contracture in patients who have bottomed out implants. This is because the bottoming out indicates to me that your tissues have stretched and relaxed allowing the implant to drop. This does not happen in people who are prone to forming breast capsules.
The repair should work and I have not see capsules form in patients I have done this type of correction on.
Many factors cause capsular contracture. In my opinion the most important are bleeding during surgery, poor technique, and failing to do implant displacement exercises or massage after surgery.
Massage is the most important thing you can do after surgery to lessen capsular contracture.
Ibuprofen has smooth muscle relaxant properties and is believed by many to lessen contraction post op. Vitamen E has also been recommended. Both of these supplements are recommended anecdotally and have not been proven in controlled studies to prevent capsules.
Discuss taking these meds with your surgeon before you take them.
Good surgical technique and post operative massage are your best options.
