Loretta Lynn has postponed a few concerts, due to a torn knee ligament that requires minor surgery.

Philadelphia's Temple Performing Arts Center and Washington, DC's 9:30 Club are some of the venues having to tell ticket holders that the 78-year-old country legend must reschedule for a later date.

"She regrets disappointing any of her fans, but looks forward to rescheduling her shows as soon as possible," a spokesperson tells TheBoot.com.

Fans learned the extent of her discomfort at a concert on March 4 in Buffalo, New York, when she asked the crowd for their permission to continue to last of her show while seated. Noticably toughing out the pain, Loretta held the hand of her son, Ernest Ray, as she got out of the chair to sing a medley of gospel songs before closing the show with "Coal Miner's Daughter."

She also had to take a seat after about 15 minutes of standing at a recent concert in Greensboro, N.C.

A sure trooper, Loretta is known for continuing her packed concert schedule in sickness and in health. The icon has performed shows until just a few days before she underwent knee surgery in 2000, and she kept performing in 2009 after a bad bout with the flu.

Loretta received many honors last year when she marked her 50th Anniversary in show business. In addition, she will be among those honored at "Girls' Night Out: Superstar Women of Country - the Concert of the Year," at the MGM Garden Arena in Las Vegas on April 4.

Feel better, Loretta!
