Does AlloDerm attach itself to inside of breast and implant. Can I rotate my implant by manipulation to get rid of rippling?

Typically Alloderm will incorporate into the tissue of the body.  If the sling was done to hold the inframammary fold the internal suture line can hurt for 6-8 weeks.
Hope this helps,

Acellular dermal matrix becomes apparent to patients' tissues, not breast implants. Therefore, the breast implants can still move or shift in their "pockets".Palpability and rippling of breast implants may be related to several factors. These include the amount of soft tissue and breast tissue coverage over the breast implants, the position of the breast implants (submuscular versus sub glandular), the type of implants (saline versus silicone), and the degree of overfilling of saline filled implants. Also, breast implant displacement problems (such as bottoming out or lateral displacement) may play a role when it comes to increase breast implant rippling.
Generally, weight loss will extension weight any rippling/palpability of the implants. Deflation of saline implants will also increase the rippling/palpability of the implants.
Correction of the rippling may involve further surgery including implant pocket exchange if possible (sub glandular to submuscular), implant exchange if possible (saline to silicone), capsulorraphy (adjustment of the surrounding breast implant capsules to prevent displacement) and/or the use of allograft (acellular dermal matrix) to provide an additional layer of tissue between the implant and the patient's skin.  
  I hope this helps.

Alloderm incorporates into the breast tissue and your cells grow into it. It’s unlikely that you can manipulate an implant to get rid of rippling, at least not permanently. I’d suggest booking an appointment with your surgeon to be examined for a more specific answer. Best of luck!
