Ankle Osteoarthritis

When you are experiencing pain in the ankle, it is often from a type of arthritis affecting this joint known as ankle osteoarthritis.


Lisfranc Injury

This is an injury of the foot in which one or more of the metatarsal bones are displaced from the tarsus.


Syndesmosis Sprain

A syndesmosis sprain, also referred to as a high ankle sprain, occurs as a result of ligament damage in the ankle.


Hallux Rigidus

A form of degenerative arthritis, which can cause pain and stiffness in the metatarsophalangeal joint (the joint where your big toe—the hallux—joins your foot).


Flat Foot

A condition in which the entire sole of the foot touches the floor when standing.


Osteoarthritis of the Foot

Osteoarthritis is a type of arthritis that can cause pain and inflammation in any of the joints in the foot.



A bunion, medically termed hallux valgus, occurs when the big toe leans too far into the second one and causes a swelling on the side of the big toe joint



Hammertoes are a potentially serious problem for people who suffer from poor circulation or diabetes. It is easy to diagnose through a quick examination.


Peroneal Tendinitis/Dislocation/Subluxation

The peroneal tendon’s primary function is to stabilize the ankle and foot, protecting them from sprains. Dislocation or subluxation is common if in athletes.


Ligament Sprain/Instability

When you injure one or more ligaments in your ankle, typically on the outside of your ankle, it is known as an ankle sprain or sometimes called a ligament sprain/instability.


Osteochondral Defect (OCD)

This is any type of damage to articular cartilage and underlying (subchondral) bone.

Dr. Ahmed did my ankle surgery yesterday morning. I had my last 2 ankle surgeries at another institution out of town 15 years ago and had a rough recovery leading me to this third one. This time was a fantastic experience! From the first visit with Dr. Ahmed and Danielle to the actual surgery yesterday I have been impressed with the professionalism, knowledge, and caring nature of Dr. Ahmed, the staff at Nilssen, and Andrews. Thank you for taking such good care of me and setting me up for a smooth recovery!read more

I wish we would have found her sooner, but I am so thankful for her more

Virginia Willard
My friends who are surgeons unanimously referred me to Dr Eric Nilssen, when my ankle was broken. His office arranged my fist appointment on a Monday morning following Vereran's weekend, after I contacted them about 4 pm on a Friday afternoon. Dr. Eric and his staff were spot on. I had issues post surgery with my initial cast and Justin was immediately responsive. Immediately, he had me come into the office and removed the old cast and replaced it with great care. Many of us don't realize the impact of the cast on tour body part and being sensitive to it is very important. I would only go to Dr Nilssen for ankle issues. I'm one week post surgery and will review again once I'm off the cast, crutch and back to more

As one of Dr. Nilssen's earlier patients in the area, I have referred many to his care. After several ankle fractures and reconstructions, his expertise has had me walking in 3 inch heels, scuba diving and walking without a limp or pain since he resolved the issues. Extremely smart, innovative and patient focused, I would not recommend another specialist for foot and ankle care. With such vision and commitment to care, start and end your care plan with his team. It will be time and money well more
