1. An implantable orthopedic medical device comprising:
- a biodegradable polymer stereocomplex comprising a biodegradable polymer comprising a first enantiomer and a second enantiomer, the biodegradable polymer is immobilized on a filler particle prior to being contacted with an initiator and an optional catalyst,wherein the implantable medical device initially degrades at a first degradation rate and subsequently degrades at a second degradation rate that is faster than the first degradation rate.
