MEMPHIS, Tenn., April 22 /PRNewswire-FirstCall/ -- As evidence of its drive to return knee pain sufferers to a lifetime of physical activity, Smith & Nephew ( SNN, LSE: SN) Orthopaedics Division today announces the results of unprecedented testing on its VERILAST technology for knee replacement implants.
