Lindsey Vonn thinks her new titanium knee could start a trend in skiing. And pro sports in general

Lindsey Vonn thinks her new titanium knee could be the start of a trend in ski racing. The 40-year-old American standout had replacement surgery in April and returned to the World Cup circuit after nearly six years last weekend. She says her knee feels “amazing" and that "it’s something to seriously consider for athletes that have a lot of knee problems.” Her surgery was the first of its kind in World Cup skiing. Vonn had a robot-assisted surgery in April with part of the bone in her right knee cut off and replaced by two titanium pieces. She was planning her comeback a month later.
