When it comes to joint implants, one size does not fit all. The modular design of the INBONE ankle allows the physician to select the appropriate components based on patient size and bone structure.

“After a lifetime of foot/ankle pain and limitation due to a congenital defect (tarsal coalition), I developed severe arthritis in both ankles. I spent two years carefully researching the alternatives available for my severely deteriorated ankle joints. Because of the severe malalignment, it was my understanding that the other ankle replacement models may not work. Until I learned of the INBONE ankle model, I was preparing for double amputation in hopes that I would have less pain and be more mobile with those prostheses.”

The INBONE Total Ankle is intended to be used to treat patients with ankle joints damaged by severe arthritis or a failed previous ankle surgery. The INBONE Total Ankle is intended to give patients limited mobility by reducing pain and restoring movement in the ankle.

“I was unable to walk even a block without excruciating pain and used a mobility scooter to get around inside the house. I used motorized carts in grocery stores and a wheelchair in public facilities like airports, hotels, museums, galleries, etc. Severe pain (8-9 of 10) was constant in my increasingly limited daily activities. I took prescription anti-inflammatories and Vicodin just to get around the house, and Neurontin when the pain was worse at night. While these medications helped, the chronic pain had a very negative effect on my mental and emotional well-being, in addition to severely limiting my physical movement and activities.”

“At my first consultation in May 2006 it was determined that the INBONE ankle was a good match for my ankle problems, and we scheduled the first surgery for July 2006. Because my insurance company considered ankle replacement to be “investigational”, I had to go through the entire appeal process before it was approved. Finally, in February 2007 I received my first INBONEankle and was weight-bearing at 8 weeks. I’ve had no pain, swelling, or other problems during the recovery period. In fact, with only one good ankle, I enjoyed the most active and pain-free period in the last 20 years. For example, I was able to pick blueberries on rough ground, walk for an hour through the Saturday Market, and do my grocery shopping standing up.”

Not everyone is a good candidate for the INBONE Total Ankle. Talk to your doctor to discuss your lifestyle and health to find out if surgery with the INBONE Total Ankle is a good option for you.

“In October 2007 I received the second INBONE ankle and the early part of the recovery has been exceptionally smooth and pain free. Next week I’ll be out of the cast and learning to walk on my own two new feet! I’m looking forward to a full and active life with functional ankles for the first time ever!”

Many factors contribute to the length of hospital stay and rehabilitation. These factors include, but are not limited to, your age and health at the time of surgery as well as your surgeon’s determination of the appropriate hospital stay and rehabilitation. Additionally, there are risks associated with ankle replacement surgery such as pain and bruising, damage to blood vessels or nerves, infection, or blood clots that can travel to your heart or lungs. If you experience these complications, your hospital stay may be extended.

Once you have healed, there is the possibility that the bone surrounding the INBONE Total Ankle may lose its ability to support the implant. If this occurs, additional surgery may be required to replace the implant or fuse your ankle. Additionally, it is unknown how long the implant can be expected to perform well once implanted.


These results are specific to this individual only. Individual results and activity levels after surgery vary and depend on many factors including age, weight and prior activity level. There are risks and recovery times associated with surgery and there are certain individuals who should not undergo surgery.
