The present invention provides branched polymers which can be used as lubricants or shock absorbers in vivo. For example, the inventive polymers can be used as viscosupplements, viscoelastics, tissue space fillers, and/or anti-adhesive agents. Also provided are pharmaceutical compositions comprising the inventive polymers and methods of using them including, for example, in the treatment of arthritic and sport-injured knee joints; in reconstruction or cosmetic procedures, intervertebral disc repair, treatment of vocal cord problems, treatment of urinary incontinence, and prevention of adhesion formation following abdominal or gynecological surgery.
