Taiwan singer-actress Rene Liu says she may go on hiatus after a concert this coming Saturday, because of a long-time knee injury that threatens her ability to walk.

Liu was recently spotted seeing a doctor alone at the Chung Shan Hospital in Taipei, and later told the media that she has experienced pain in her right knee for more than two years.

The 38-year-old star says the pain resulted from too much pressure she had put on her right knee because the left one was injured in a car accident when she was in high school.

Liu's busy career has kept her from surgery. After the diagnosis two years ago, she completed four films, but the pain became worse. She now finds it difficult to climb or walk down stairs. Her doctor warned that if she continues to postpone surgery, she might eventually become wheelchair-bound.

Liu is scheduled to perform at the Taipei Arena on November 29. She said an operation would follow two days later.

When asked about her future plans, Liu said she would take a rest first and think about what to do next.
