Walter Wallberg to undergo knee surgery in May

Walter Wallberg finished fourth in the moguls event in Milan/Cortina, failing to defend his Olympic gold. He will undergo surgery in May for a meniscus and cartilage injury in his knee, which causes him significant pain while skiing. Wallberg, who is also dealing with a bad back, has a career marked by successes, injuries, and operations, as depicted in the documentary 'Walter vs Walter' that premiered in Stockholm before he traveled to Italy for the Olympics.
