Freeman and colleagues report the design rationale and early clinical outcomes of the Freeman-Swanson total knee prosthesis across 69 arthroplasties (1970–1972). The study asks whether a roller-in-trough, cruciate-sacrificing surface replacement can relieve pain, restore function, and correct deformity while avoiding the fixation failures of fully-constrained hinges.
