Princeton Orthopaedic Associates, P.A., II was formed in March of 1992, the result of the merger of two successful orthopaedic practices in Princeton, NJ: Orthopaedic Associates of Princeton, P.A., founded in 1974; and Princeton Orthopaedic Group, founded in the mid-1960s. In 1987, we opened our state-of-the-art flagship office located at 325 Princeton Avenue.
