Patent ID: 8895054

Claim:
A method for lubricating a joint of a mammal, the method comprising: administering into a cavity of the joint having a first temperature a composition consisting essentially of liposomes, wherein said liposomes are multilamellar vesicles (MLV) dispersed in a fluid medium, the liposomes having a mean diameter of between about 0.8 μm to about 10 μm and consisting essentially of membranes including at least one phospholipid (PL) selected from the group consisting of dimyristoylphosphatidylcholine (DMPC) and a mixture of DMPC and dipalmitoyl-phosphatidylcholine (DPPC), the membranes having a phase transition temperature in which solid ordered (SO) to liquid disordered (LD) phase transition occurs, the phase transition temperature being at a temperature of about 20° C. to about 39° C.; the phase transition temperature being lower than the first temperature.
