# Los Angeles Orthopedic Surgery Specialists > LAOSS is a board-certified orthopedic group practice with eight offices across Greater Los Angeles, treating the full range of musculoskeletal conditions from knee, hip, shoulder, spine, hand, foot, and sports injuries to joint replacement, arthroscopy, and interventional pain management.
