The New York Times highlights Lindsey Vonn’s remarkable return to elite ski racing after a partial knee replacement by Martin W. Roche, MD, knee surgeon and director of arthroplasty at HSS Florida, using an innovative, robot-assisted technique. By replacing only the damaged portion of her knee and preserving key structures, Dr. Roche helped restore the stability and strength Vonn had lacked for years—allowing her to withstand the extreme forces of World Cup downhill skiing. Her unprecedented performance is giving Dr. Roche valuable insights into implant durability under extraordinary conditions and setting new expectations for what patients can achieve after partial knee replacement.
