Abstract: Articles for increasing lubrication of a joint are described herein. The articles include resorbable, biocompatible particles having a glass transition temperature within a joint of less than about 37° C. and capable of increasing fluid movement within the joint compared to synovial fluid, viscosupplemental fluid, or combinations thereof. A composition for increasing lubrication of a joint is also disclosed. The composition includes the resorbable, biocompatible particles and a carrier fluid. Methods of lubricating a joint and treating disease affecting the joint such as osteoarthritis are also described herein. The methods include introducing the resorbable, biocompatible particles into a joint.
