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.

Just finished my last laser treatment. I am PAIN FREE for the first time in over a year!!! I mean the kind of pain that wakes you up in the middle of the night and it's so bad you contemplate chopping off your own hand just to get some relief. I was facing an $800 never conduction test that wasn't going to do anything for me and surgery that was going to put me out of commission for 2 to 3 months (ain't no body got time for that)! I cannot say enough nice things about the staff. They were all so nice and helpful. They obviously love helping people. If you have chronic pain of any kind, do yourself a favor and check this out!!! 85 to 95% success rate. 100% success in my case!

Dr. Ahmed is an amazing surgeon- she wants her patients to be able to get back to the activities and sports that they enjoyed prior to their injury. She’s very smart and she only performs surgery when it is absolutely necessary. She has a great bedside manner and I can tell she really cares about the outcomes of her patients. Her staff is equally as amazing. Libba at the front desk made sure all of my paperwork for insurance was perfect and on time. Danielle answered every single question I had before and after surgery and she was always very patient and sweet with me. Justin is great- he’s very personable, and he makes you feel more at ease about having to wear a splint and cast for weeks (he also takes his time when replacing your splint or cast so that he is sure it will be as comfortable as possible). All-in-all, I have nothing but praise for Dr. Ahmed and her office. If you want to be in good hands, I highly recommend her!!!

Thank you again Dr Nilssen. With each new milestone I realize that I am only physically able to achieve them thanks to your expertise in my surgery. 1 year after surgery (2016)Michael and I won the Hobie 20 national championship and this year in November we are thankful to be a part of team USA at the Hobie 16 World Championship.
Truly I wouldn’t be able to continue to compete in this sport I love if I hadn’t found you to fix my ankle.

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!

Dr Ahmed is amazing. She gave my daughter outstanding care! She went to her with complications after a broken Sesamoid bone in her right toe. Dr Ahmed found the problem and also diagnosed plantar fasciitis. Prescribed special shoe inserts and an apparatus to wear at night. My daughter suffered for a year through different doctors. I wish we would have found her sooner, but I am so thankful for her now.

I feel like a valued patient at Dr. Ahmed's office. All my concerns were addressed, and my questions answered. I feel comfortable going into surgery knowing I will be well taken care of. The office staff is friendly and professional, and Dr. Ahmed took the time to explain everything and helped me to understand what would be taking place and what to expect after the surgery. I know I am in good hands.

Dr. Nilssen and his staff are AMAZING!! Had ankle replacement with another doctor 5 times in 2 years (same doctor). It was getting worse. I couldn’t walk for over 800 days. Went to Dr Nilssen and 2 surgeries later (corrective and repair) and only 103 days later I’m walking! I tell everyone I know about Nilssen Orthopedics. They will never know how much I appreciate what they’ve done for me and how they fixed what had been done. I can go back to living. Thank you!!

The staff is very helpful and take the time to answer your questions and concerns. Dr. Nilssen was extremely confident in my full ankle replacement and was the first Dr I have visited with this much confidence of my full recovery. I am 12 weeks into the recovery process and physical therapy. I am looking forward to my visit again in 8 weeks to see the results.

Dr. Nilssen removed a neuroma from my foot 1 year ago and more recently had another removed by a different doctor. I had much less post surgical symptoms after the surgery performed by Dr. Nilssen. I will definitely go back to him for the next surgery as I have more neuromas. Dr. Nilssen and his staff are very professional and friendly!!

A friend referred me to Dr Nilssen and I'm so thankful. I have had two surgeries, the first in September 2016 and the second in December 2016 for bunion removal. The procedures weren't bad, outpatient. However, I was shocked at how painful the recovery has been. The care and concern shown by Dr Nilssen and his staff has been amazing. I'm glad I had the procedures done and highly recommend Dr Nilssen and his team.

This was my second procedure using Dr. Nilsssen, the man knows his business! If you have issue with your feet don't waste your time on other doctors!
His new office is amazing! On my first visit I had the MRI on site and procedure scheduled, words can't explain how easy he has made it to get better.
Michael F.
21:13 16 Dec 16
Dr Nilssen has preformed two different procedures on my ankle and both times I experienced wonderful care and results. At one time, Dr Nilssen was treating 3 members of my family and 2 very close friends. We were all very pleased with his care and expertise. I would go to NO ONE else! He is the BEST!
Virginia W.
22:35 15 Dec 16
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 normal.
Pandora de B.
21:26 23 Nov 16
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 spent.
