Chad Crittenden

39 days, 18 survivors, 6 weeks of filming. Chad Crittenden, 35, was chosen as the first amputee to participate in CBS’ Survivor Vanuatu. Remaining on the show for 27 days, Chad, a below-the-knee amputee, persevered through starvation, dehydration, discomfort, constant temperature fluctuations, and of course 24-hour camera surveillance.

Prior to the show’s filming Chad prepped with his prosthetist, Wayne Koniuk of San Francisco Prosthetic-Orthotic Service, working on basic exercises such as entry and exit out of the water and strength training for optimum performance. “There were no complications with my prostheses during the show’s filming. Unbelievably, my Renegade® endured everything I put it through – sand, surf, and all of the crazy challenges. However, I lost 15 pounds in 27 days and that affected how my socket and liner fit — I had to overcompensate with extra socks.”

Chad CrittendenYou would think that being an amputee on Survivor would affect you mentally, emotionally and physically, but for Chad this was not the case. In fact, he would have planned the same strategy had he not be an amputee. “I have pretty high standards so I am satisfied with my performance, but not elated. Under the circumstances, there were a few challenges, for instance the balance beams that I caught myself on and feel I could have trained harder for.” Chad’s appearance on the show exposed the public to amputees and their capabilities. “I’m sure it dispelled stereotypes, and I hope that it inspired amputees worldwide,” he said.

Chad was most enthused by the production itself, claiming that after watching Survivor for years, “I finally witnessed first-hand the real behind-the-scenes drama that the viewers wish they could see but don’t,” he said. “The technical aspects and coordination that go into the show is colossal, there are literally hundreds of people working together to make the show a success.” According to Chad, each show gets better than the last.

At Freedom Innovations, the Vanuatu Season will always remain our favorite. We were thrilled to see an amputee performing such great acts while wearing the Renegade. It was a true surprise to everyone at the company and a pleasure to turn on the television every Thursday night to root for “one of our own”. Chad’s success is a measure of his determination and skill as well as a demonstration of what we have long known to be a top of the line product. We couldn’t be more proud of Chad and his accomplishments.

Frequently Asked Questions

There are a lot of prosthetic devices available today.  How do I know which prosthetic foot or knee is best for me?                         

There are many variables that must be considered when selecting a prosthetic foot or knee product.  This includes the height and weight of the product as well as the functional benefits it offers.  There are also considerations around your body weight, requirements for battery-power, water resistance, etc.  Your mobility ‘K-Level’, as defined by Medicare, will determine the types of technology your insurance will cover.  All of these things must be carefully reviewed and analyzed by your prosthetist.  And it’s important that you voice your lifestyle concerns, functional goals and aspirations as a part of the evaluation process.

We offer a broad range of prosthetic foot products in an effort to meet the varying needs of amputees globally.  Our foot products are divided into six subcategories based on the type of user profile they accommodate best.

Can I buy Freedom Innovations products direct?

Freedom Innovations products should be fitted and ordered by qualified prosthetists. We are unable to sell directly to the public. Your prosthetist will make sure that you are measured and fit properly to achieve the best possible results.  He or she will also be able to discuss pricing and insurance coverage.

How do I find a prosthetist in my area?

Use our Prosthetist Finder tool to find a prosthetist in your area familiar with our product line. Many of these prosthetists have completed the Freedom Institute of Technology’s (FIT) clinical education programs designed to ensure the best outcomes with our products. This includes coursework on carbon fiber foot selection and fitting and how to properly fit and program the Plié Knee.

How soon after the amputation surgery can a prosthetic foot or knee be fit?

The process can begin once your residual limb has healed. Normally it takes approximately four to eight weeks to heal as long as there are no post-operative complications involved.

Will I be able to do all of the things I did before I lost my limb?

Our goal at Freedom Innovations is to allow you to achieve your full potential. We have many, many success stories in which our customers have gone back and excelled at the activities they once enjoyed.  Some individuals even find that they are motivated to challenge themselves with new hobbies and athletic activities.  The key is staying motivated and working with a good network of healthcare professionals including your prosthetist, physical and occupational therapists, and others.  And of course, we are committed to providing the prosthetic technology that will enable you to achieve your goals.

Is wearing a prosthesis painful?

Acclimating to life as a new amputee is not without its challenges.  Achieving a good socket fit is critical and it can take time because revisions are often needed to accommodate your limb, which will change in size and shape especially in the beginning.  However, your prosthesis should not be painful.  If you are uncomfortable, especially if you begin to experience skin breakdowns, contact your prosthetist for an adjustment.  He or she is committed to your health, comfort and overall well-being.

How will my prosthesis stay on?

There are many different suspension options to ensure that your prosthesis stays attached to your residual limb.  This includes various socket shapes, pin locking systems and vacuum suspensions. Talk to your prosthetist about the best option for your anatomy and your lifestyle.

What kind of shoes can I wear with my foot product?

You can wear many different types of shoes, including boots, sneakers, dress shoes, sandals and even high heels with certain prosthetic foot technology.  Our Runway foot allows you to walk barefoot at home (no heel height) in the morning and with a simple adjustment, transition to wearing heels up to 2 inches (5 cm) for work or a night out. We also offer the broadest range of sandal toe options for those that love to wear ‘flip-flops’ or sandals during the summer months. Read more here.

Lastly, don’t forget to bring your favorite shoes to your prosthetist so the possibilities can be explored and, if necessary, a fit test can be conducted.

How long will my prosthesis last?

The life of your prosthesis will vary depending on how much you use it, how well you take care of it, and the general environment in which it operates.  Our foot and knee products are generally sold with a 36 month warranty.  (Product-specific warranty periods are listed on each product webpage.)  Liners have a shorter life expectancy and are sold with a 6-12 month warranty.

Ask your prosthetist for instructions regarding the proper care and cleaning techniques for your prosthetic leg.
