loading the aseptically formulated PGGA into a syringe; and

placing the formulated PGGA into a diseased joint by interarticular injection.

2. The method of claim 1 , wherein the PGGA has a molecular weight of at least about 250,000 Daltons.

3. The method of claim 2 wherein the PGGA has a molecular weight of at least about 1 million Daltons.

4. A method of treating a degenerative joint disease, comprising:

providing pharmaceutical grade poly-gamma-glutamic acid (PGGA) having a molecular weight of at least about 250,000 Daltons;

aseptically formulating the PGGA at a concentration of from about 10 mg/ml to about 30 mg/ml;
