Section I • Introduction
Congratulations on obtaining your new iFIT
transfemoral prosthesis. We hope you will enjoy the
comfort and adjustability of the device. Years of
research and development have gone into the design
of this prosthesis so that we could provide you with
the best possible product.
Below you will find a series of instructions which are
essential to follow in order to get the best results from
your prosthesis and prevent any problems. Please note,
these pictures feature a white inner liner while most
devices have our latest black material. Please follow
these instructions so you can continue to achieve a
great fit. We strongly suggest using the wear schedule
on page 10 so you can check your residual limb and
gradually adjust to the device. Even though the iFIT
Prosthesis is designed to be easily fit and aligned we
recommend that only an iFIT certified prosthetist can
customize and fit this device to your needs.
Thank you for choosing iFIT Prosthetics!

PATIENT ADVISORY WARNINGS
The prosthetic socket must be securely buckled at all times
when you are standing or walking. The buckles must be
completely closed so that the locking mechanism prevents
them from opening. Your limb must be completely in the
socket and the pin suspension system fully engaged—you
should not be able to pull the device off of your limb.
Your iFIT prosthetist will select the other components that
accompany the socket according to your body weight and
activity level. These include the prosthetic knee, silicone
pin suspension liner and foot. If your weight or activity level
changes, or if your prosthesis becomes less comfortable,
please notify your healthcare provider.
The socket should be comfortable to wear. If you have
any discomfort, alert your iFIT prosthetist. The healthcare
provider will test your ability to use the device while in their
clinic to ensure you can use it safely and properly.
To minimize the chances of any problems occurring, this
prosthetic device has undergone extensive engineering
testing by iFIT Prosthetics. You should always wear a silicone
locking liner (this is the liner with a pin attached) that is
compatible with the suspension in the device. You should
also ensure it is buckled tightly and securely to prevent
rotation during walking.
You must carefully follow the directions of your iFIT
prosthetist and the instructions contained in this brochure.
Failure to do any of the following could result in tripping
and falling, device failure, skin breakdown, or cause other
serious harm.
• The pin attached to the silicone locking liner should be
fully inserted into the bottom of the socket prior to use.
Check to see that the socket does not pull off once you
engage the pin. You will hear a clicking noise as the pin
locks into the locking mechanism.
• Be sure to check that the prosthesis is firmly attached
to your limb.
• If your silicone liner is worn out replace it with one
prescribed by your healthcare provider that works with
the iFIT prosthesis system. The silicone liner should be
trimmed higher than the prosthesis to prevent rubbing/
skin breakdown.
• Do not stand or walk without buckling all buckles and
checking to ensure that they are locked.
• Do not make adjustments to the buckles while standing.
Sit down and then make any buckle adjustments.
• The prosthesis must fit snuggly and comfortably around
your leg to work properly. Loosening the buckles too much
may alter walking and lead to falls.
• Let your prosthetist know if there are any areas of
excessive rubbing or pinching so they can modify
the socket.
• The iFIT transfemoral (above knee) prosthesis is not
designed for vigorous activities such as running.
• If there is pain in the limb, reduce the tightness of the
buckle one notch. Buckling too tight may cause excess
pressure or reduce blood flow to the limb. If the pain
continues despite loosening the buckle, take it off and
contact your healthcare provider.
• Only a certified iFIT prosthetist may fit and align
this device.
• Do not wear the prosthesis without a protective silicone
locking liner (with pin) which is supplied by your
healthcare provider.
• If the inner liner shows signs of excessive wear or tears
please contact your prosthetist to have it replaced.
• Do not rest or sleep with the prosthesis against your
opposite leg. Doing so may cause skin irritation
or breakdown.
As with any prosthesis there are always potential problems
that may arise. It is important that you use the iFIT Prosthesis
exactly as described in this guide. Failure to do so may result
in one or more of the following problems:
1. Prosthetic failure.
2. Residual limb skin breakdown.
3. Pain in residual limb with use of the prosthesis.
4. Risk of fall while using the prosthesis.
5. Reduced circulation (blood flow) to a limb if it is buckled
too tightly.
If you have any concerns with your prosthesis please
contact your iFIT prosthetist first.

Section II • iFIT Prosthesis Components*
Please use this guide in any communications regarding your prosthesis. This will help the healthcare provider and the
manufacturing company when responding to any questions you may have.
*The pictures in this guide show a white liner, we have recently updated our product to include a black liner.
The white is pictured to delineate the liner and the other socket components.

Check the silicone locking liner and make sure the pin is secured and not
loose. This liner should be rolled onto the residual limb without any gaps
or air bubbles at the end. Make sure the pin sticks out directly below the
limb and that it is not angled in one direction. This liner should be trimmed
above the edge of the socket to protect the skin.
1. Begin in a seated position while wearing a silicone locking liner.
2. Slide the prosthesis onto the residual limb making sure the prosthesis
is in line with the limb. If the prosthesis is put on at an angle the pin will
not go in.
3. Make sure the pin engages in the lock with at least 3 clicks.

1. Make sure you are seated.
2. Make sure the flap with the hooks are on the outside flap.
3. The bolt on the lateral upright should be facing directly upward.
4. We recommend starting with the middle or top buckle first.
The lower buckle is secured last.
5. You may need to start looser and then gradually tighten the cables
by buckling and re-buckling until the optimal hook is reached. You may
notice that once you tighten one area another cables loosens- continue
to optimize until the right tightness is achieved.
6. Always make sure your hand is on the outside of the buckle.
7. If you notice that the edge of the liner or flap with the hooks is running
into the lateral upright, please contact your prosthetist to have this piece
trimmed down.
8. Always check that the buckles are securely fastened by checking that
the safety latch is engage.
BUCKLING THE PROSTHESIS

10
1. Once buckled, stand up to test out the tightness.
2. If too tight or too loose, return to a seated position.
3. Move the cable 1-2 notches either forward or backward until
the right fit is achieved.
4. Once you find a snug fit, you can also mark this notch with a marker
if needed. We have found a silver marker works well.
Important
If you notice any excessive movement of the limb inside the socket,
contact your prosthetist immediately. Many persons with amputation
shrink in size and may need their prosthesis adjusted by the prosthetist.
MAKING ADJUSTMENTS USING THE BUCKLE
1. Always begin in a seated position.
2. Press the safety latch on the buckle rearward in order to lift the buckles
and unbuckle the cables.
3. Press the pin release button located on the lower lateral side of the
prosthesis. This button is recessed and must be held down while the limb
is pulled out of the prosthetic.
4. The limb should slide out easily. If you are having difficulty make sure you
are sliding the prosthetic off in the direction of the pin- otherwise the pin
will be caught at an angle. One way to accomplish this is by buckling the
middle buckle, then pushing the release button.
TAKING OFF THE PROSTHESIS

11
1. You should clean your silicone locking liner after each use and allow
to dry. Please refer to the manufacturer instructions.
2. The prosthesis can be cleaned with a damp cloth.
3. Regularly inspect the anti-rotation pads and liner of the device.
If either is damaged or has moved please contact your prosthetist.
4. Periodically inspect the cables on the device to make sure they are not
showing signs of excessive wear (i.e. fraying). If they do, please contact
your prosthetist.
5. The prosthesis can be worn in the water if used with an appropriate
waterproof knee and foot. Please discuss with your prosthetist prior to
using in the water.
6. After using in freshwater, empty all of the water out of the device by
turning it upside down. Allow to dry completely before using again.
7. If using in saltwater, make sure you rinse the entire device out with
freshwater. Next, refer to freshwater directions above.

Section V • Frequently Asked Questions
1) Are there different sizes of the iFIT Prosthesis?
Yes, there are two different sizes: standard and wide. Each can be adjusted by the wearer when volume
changes occur. Larger adjustments can be made by the prosthetist.
2) What happens if I have reached the limit of how far I can adjust my prosthesis?
Always contact your prosthetist if the device is not getting tight enough; it is critical the prosthesis has
a snug fit. Your prosthetist can make larger adjustments by making simple modifications to your prosthesis.
3) How many times a day should I adjust the buckle system?
This will depend on how much volume change you experience. We suggest assessing your device every
couple of hours or after extended ambulation/activity to ensure it is snug.
4) Can I wear the prosthesis in the water?
Yes, you can wear the prosthesis in the water provided you have a waterproof foot and knee. If you are
wearing the prosthetic in saltwater always rinse with freshwater after.
5) What is the max weight of the prosthesis?
The maximum weight is 300 pounds.
6) Are parts on this prosthesis replaceable?
Most parts of the prosthetic can be replaced. Contact your prosthetist if you notice excessive wear in your liner,
cables or other components.
7) How long is my device warrantied for?
Every iFIT prosthesis is guaranteed for a one year period.
8) This prosthesis does not go as high up my hip as a conventional prosthetic, will I have less stability?
During our testing we found that the prosthesis does not need to go higher up the limb to provide stability.
By having the prosthesis tightly buckled, there is enough purchase to provide adequate stability for ambulation.
9) Is there a certain order which I should use to buckle the prosthesis?
We suggest starting with the middle or upper cable first and the bottom last. You may need to re-adjust
a couple times to find the appropriate fit.
10) Can I get this device with suction suspension or vacuum?
The iFIT Prosthesis can only be used with pin suspension at this time.
