Claim 0:
1. A method for morselizing a biodegradable drug delivery composition comprising at least one pharmaceutically active principle comprising:
(1) formulating a biodegradable drug composition comprising
(a) a biodegradable triblock copolymer having the formula:

PLAv-PEGw-PLAx, wherein v and x are the number of repeat units ranging from 24 to 682 and w is the number of repeat units ranging from 4 to 273 and v=x or v≠x;
(b) a biodegradable diblock copolymer having the formula:

mPEGy-PLAz 

wherein y and z are the number of repeat units with y ranging from 3 to 45 and z ranging from 7 to 327, wherein the polyethylene glycol chain in the triblock and/or the diblock copolymer is 2 kDa and
wherein the ratio of the biodegradable triblock copolymer of (a) and the biodegradable diblock copolymer of (b) is 3:2 to 1:19 in said biodegradable drug composition and
(c) at least one pharmaceutically active principle;
(2) administering said formulated biodegradable drug delivery composition in at least one joint of a patient, such that it is contained within the articulating joint capsule.
