At Advanced Foot and Ankle Center, we see all kinds of foot and ankle issues starting from the tips of the toes and going all the way up the leg and everything in between. One common complaint that we hear is a lump or knot on the bottom of the arch. Some people have pain and some don't. Sometimes they grow and others never do. In almost all cases, this is a plantar fibroma.
A plantar fibroma is a benign thickening of the plantar fascia. This is the large ligament that runs from your heel to the ball of the foot and is the main supporter of your arch. The portion of the ligament can become thickened from trauma or repetitive pressure to the area, but the conclusive cause has not yet been identified.
Your provider will take a thorough history and examine both your lower extremities before making the diagnosis. Sometimes x-rays or an MRI is needed to confirm the fibroma. Treatment for plantar fibromas starts conservatively. This can begin with topical medications, custom shoe inserts, cortisone injections and physical therapy to try to reduce the size and pain to the area.
If conservative options fail, the fibroma can be removed surgically in the operating room.
At Advanced Foot and Ankle Center, our providers have had experience dealing with this issue conservatively and surgically. If you have questions about this or any other foot and/or ankle issue. Please call us at 972-542-2155.
Have a wonderful day,
