FOREWARD
This manual has been written for operators of the Furniss Corporation Continuous Passive Motion (CPM) Therapy Unit.
It contains general information for operation, precautionary instructions and maintenance recommendations. In order to obtain
maximum life and efficiency from your Furniss Corp CPM Unit, and to assist in the proper operation of the unit, read and
understand this manual thoroughly. It is recommended that all clinicians and support personnel become familiar with the
operating procedures, as well as the indications, contraindications, warnings and precautions prior to administering patient
treatment.
Product Description
Continuous Passive Motion is a postoperative procedure designed to aid in patient recovery after joint surgery, soft tissue
surgical procedure or trauma. The treatment method has been practiced for more than 30 years. This unit is typically used
postoperatively for total knee replacement and Anterior Cruciate Ligament (ACL) repairs.
After extensive joint surgery patient attempts at joint flexion can cause considerable pain, dissuading the patient from effective
joint motion. Failure to achieve proper rehabilitative flexion can lead to stiffening of the tissue around the joint. Eventually, this
condition may cause intra-articular adhesions (formation of scar tissue) and extra-articular contractures (shortening of a muscle
or tendon), resulting in a limited range of motion for the joint.
Passive range of motion moves the joint gradually and slowly without the use of the patient’s muscles. The device is applied
post-operatively and can be used in both inpatient and outpatient therapy regimens. The physician will prescribe usage
instructions, including the speed of the machine, the duration of usage, amount of motion and the rate of motion increase.
Various studies have concluded that patients using a CPM machine following surgery generally reduce the risk of complications
and require less pain medication than those who do not use the CPM device after the same type of surgery.

SOFTGOODS APPLICATION
Furniss Softgoods 1828-1 are designed specifically for use with Furniss Knee CPM devices. Softgoods provide a 'troughing'
effect allowing proper alignment of the limb and a truer fit overall. Constructed with the highest quality materials. Furniss
Softgoods provide superior comfort and support for the patient.
Each Patient Softgoods kit includes five (5) pads total:
1 - Foot Boot
1 - Calf Pad
1 - Thigh Pad
2 - Auxiliary Straps
Slide the pocket of the foot boot over the end of the foot plate and secure to the
Velcro.
Secure ankle support straps on the foot boot to the foot assembly tubes on both
sides.
The calf pad is the smaller of the two square-shaped pads. Position the calf pad so
TROUGH
TROUGH
that the cut-out is facing the thigh cradle. Peel the velcro strapping from the back of
the pad, loop over the cradle bar of the unit and secure to the back of the softgood.
Be sure not to pull the softgood tight, forming a trough to allow for proper alignment.
The thigh pad is the larger of the two square-shaped pads. Position the thigh pad so
that the cut-out is facing the calf pad (the cut-outs will form a 'diamond' shape).
Begin with the tab Velcro at the very end of the thigh pad. Secure this piece to the
bottom of the thigh block**. Peel the rest of the Velcro strapping from the back of
the pad, loop over the cradle bar of the unit and secure to the back of the softgood.
Be sure to 'trough' the softgood, do not pull the softgood tight.
The two (2) auxiliary straps may be used to secure the thigh and/or calf (do not secure too tightly—leave room for shifting).
Softgoods are intended for single patient use only. Should the pads become soiled during use, spot clean by hand with mild
detergent and warm water.
Furniss Softgoods are designed specifically for use with the Knee CPM Series. Use of any other brand of CPM Softgoods may
adversely affect performance of the Knee CPM device and result in discomfort or injury to the patient.

PATIENT SETUP
Correct measurement and adjustments are required to ensure patient comfort and compliance and to achieve desired range of
motion. Check that the unit is at 0 degrees during patient setup.
Note: Use only on a stable surface.
An unstable surface could result in injury to patient and damage to the device.
FITTING THE PATIENT
Determine the length of the patient’s femur by measuring from the greater trochanter (hip joint) to the center or joint line of
the knee.
Transfer this measurement to the thigh cradle beginning approximately 1.5 to 2 inches away from the hip pivot assembly
measuring to the knee axis of the unit. Adjust the thigh cradle to match this measurement by loosening the thigh
adjustment knobs and sliding the thigh cradle to the proper length. Note: The DC2480 maximum cradle adjustment is 3
inches. Do not extended beyond this point. If patient’s thigh length exceeds these measurements, simply increase the
beginning point of measurement to 4 to 6 inches away from the hip pivot assembly.
Loosen the calf cradle adjustment knobs and extend the foot assembly. Do not remove this assembly -- only slide far
enough for patient placement. Position the patient's leg in the unit, with softgoods in place.
Slide the foot assembly toward patient accordingly leaving one half inch gap between the patient’s foot and the foot plate.
Tighten the calf cradle adjustment knobs securely.
The foot assembly may be adjusted in plantar flex or dorsi flex positions. Loosen the adjustment knobs on the foot
assembly, adjust the foot plate to the desired positioning and securely tighten the adjustment knobs.
Remember: The goal is to align the knee axis of the patient with the knee pivot axis of the CPM

PATIENT SET UP
BED STABILIZING SYSTEM
Bed stabilizer rods are included in the base of each Furniss Knee CPM. This system, in conjunction with the non-skid pad
located on the bottom of the control box, effectively prevents migration or "movement" of the unit while on a patient.
Loosen the base knobs, extend the rods to the appropriate length and tighten the knobs securely.
Stabilize the rods against a solid barrier such as a foot board.
PEDIATRIC AND PETITE PATIENT ADJUSTMENT
The Furniss Knee CPM can adjust easily to accommodate pediatric and petite patients.
Loosen the calf adjustment knobs and slide the foot assembly out of the cradle.
Loosen the foot assembly adjustment knobs (do not remove).
Rotate both foot tubes 180 degrees so that they are facing the opposite direction.
Tighten the foot assembly adjustment knobs.
Slide cradle back into the device and secure with
the calf adjustment knobs.
Note: You may apply a strip of adhesive-backed
loop Velcro to this side of the footplate for added
stability of the foot boot softgood.
