COULD YOUR KNEE PAIN BE PES ANSERINE BURSITIS?
Pain on the inside of your knee—even after a knee replacement—doesn't automatically mean your replacement has failed or you need another surgery.
Sometimes, the source of the pain is a small, inflamed bursa just below the knee.
Three tendons attach in this area, and a small fluid-filled sac called the pes anserine bursa helps them glide smoothly over the shinbone. When this bursa becomes irritated, it can cause significant tenderness and pain on the inner side of the upper shin.
Here's the aha moment: Not all knee pain comes from inside the knee joint.
Pes anserine bursitis can mimic other knee problems, including meniscus and ligament issues. Identifying the true source of pain is the first step toward finding the right treatment—and surgery isn't always the answer.
Dr. Corbett Winegar, MD, FAAOS, is the Treasure Valley's only orthopedic surgeon fellowship-trained specifically in knee care. His specialized expertise helps him evaluate complex knee pain and determine what may actually be causing it.
Don't assume your knee needs another surgery. Get the right diagnosis first.
