Case Studies
The KneeEase CPM™ has only recently been made available for the use of total knee
replacement patients at home. This latest entry into the home rehabilitation equipment
market has been driven by the success and impressive contributions of predecessor
products GenUbender™ and GenuEase™ which have been proven by thousands of
patients in clinical rehabilitation centers over the past four years. Numerous case
studies documenting the benefits of these products including difficult cases where
patients were facing potential manipulations before being introduced to these machines
have been recorded.
KneeEase CPM™ is a highly portable, motorized version of its heavier cousins— specifically designed for use at home while retaining all of the important therapeutic
benefits of its clinical counterparts. This product is now available to fulfill growing
requests by doctors for home applications which were functionally prohibited by the
lack of mobility of the earlier clinical models. Previous experience and case studies will
transfer and continue to be relevant to this home model.
Case Study #1
|
| Patient: |
K. V. |
| Dx: |
Right Total knee arthroplasty |
Date of surgery: |
May 6, 2005 |
| Surgeon: |
Robert Jackson, MD |
| History: |
Long history of right knee pain secondary to arthritic changes and
degenerative joint disease. |
Summary:
- Following the patient’s TKA surgery on 5/6/05, she experienced cardiac complications and was transferred to the ICU.
- The majority of her hospital stay was in the ICU.
- While in the ICU she did not have physical therapy and the CPM was used on a very limited basis.
- She was discharge from the hospital on 5/14/05.
- Began home health physical therapy on 5/18/05. The patient was treated 3x/week. Treatment
included therapeutic exercises as per TKA protocol and gait training. Traditional CPM was also used daily following standard protocol 3x/day for 2 hours each session. Right knee ROM was measured at 10 - 70 degrees.
- The patient was very consistent and compliant with therapy and CPM protocol, but progress was slow with regard to ROM.
- The patient had a follow up visit with Dr. Robert Jackson on 6/9/2005 in his office. He determined that the patient would require a manipulation under anesthesia if she did not demonstrate more rapid progress with her ROM.
- I talked with Dr. Jackson on 6/13/2005 and asked if I could use the GenUbender with the patient to help improve her ROM.. He agreed.
- The GenUbender was introduced to the patient on 6/15/2005. Both the patient and her husband were instructed in set up and proper use. The patient was instructed to use the GenUbender 2-3x/day for 30 mins. each session as per protocol. She was told to hold each stretch for 30 seconds both at end ranges of flexion and extension. Prior to using the GenUbender that day, the
patient’s ROM was measured at 5 - 90 degrees.
- Discontinued use of traditional CPM on 6/15/2005.
- The patient was very consistent and compliant with GenUbender protocol. She also continued
to receive therapy 3x/week via home health care. Therapist worked mostly on strengthening and
gait training. Therapist also supervised GenUbender use on his visits to ensure protocol was
being followed correctly.
- The patient continued to use the GenUbender until 7/7/2005 (total of 23 days). Her ROM on
that day was measured at 0 - 132 degrees. Physical therapy was discontinue as the patient
achieved all goals. Manipulation was avoided. Both the patient and Dr. Jackson were very
pleased.
- By way of comparison, the traditional CPM was used at home for a total of 28 days. Twenty
degree improvement was achieved with flexion and a 5 degree improvement with extension.
- GenUbender achieved a 42 degree improvement with flexion and 5 degree improvement with
extension.

Case Study #2
|
| Patient: |
M.O. |
| Dx: |
Left Total knee arthroplasty |
Date of surgery: |
8-8-05 |
| Surgeon: |
Kent Samuelson, M.D. |
| History: |
Multiple past knee surgeries, Degenerative joint disease with arthritic
changes resulting in severe pain and limited range of motion. |
Summary:
- Following surgery and hospitalization, the patient began home health physical therapy. The patient used a traditional CPM while in the hospital for 4 days, but one was not sent home with the patient.
- Permission sought from Dr. Samuelson to use GenUbender machine with the patient for the next 4 weeks to augment his home health and out-patient physical therapy. Permission granted.
- Began using GenUbender on 8-16-05. The patient was thoroughly instructed in the set up and protocol of the GenUbender machine. He was given a written copy of the protocol. Range of motion was measured on this date and found to be 15 - 70 degrees.
- The patient was very consistent with daily use of the GenUbender, following established protocol. Home health physical therapist worked with the patient on strengthening, gait training, stairs, and supervision of GenUbender protocol.
- Home health physical therapy discontinued after 2 weeks. The patient began out-patient therapy, but continued to use the GenUbender at home.
- The patient discontinued using the GenUbender on 9-17-05. Range of motion on that day was measured at 0 - 120 degrees. The patient reported that prior to his knee replacement surgery, he was unable to bend his knee much past 90 degrees secondary to pain and degenerative changes.

Case Study #3
|
| Patient: |
R.B. |
| Dx: |
Right Total knee arthroplasty revision |
Date of surgery: |
8-17-05 |
| Surgeon: |
Richard Jackson, M.D. |
| History: |
The patient had a right total knee replacement in 1992. He began having pain and instability in the right knee as of late. He was examined by Dr. Richard Jackson and it was determined that the components, particularly the joint spacer had worn out. The patient would require a total knee revision. |
Summary:
- Following the patient’s surgery and hospitalization, Dr. Richard Jackson ordered a
GenUbender machine for the patient to use at home. The patient lives in a remote area. The
nearest therapy clinic is miles away.
- A GenUbender machine was delivered to the patient’s home on 8-20-05. He was thoroughly
instructed in the set up and use of the machine. He was given a written copy of the established
protocol. Range of motion measurements were taken and found to be 10 - 85 degrees.
- The patient was contacted weekly by phone to monitor his progress and to answer any
questions he may of had. The patient was very consistent and motivated in following the
GenUbender protocol.
- September 9th, 2005 marked 3 weeks of using the GenUbender. The machine was picked up
from the patient. Range of motion measurements were taken and found to be 0 - 132 degrees.

Case Study #4
|
| Patient: |
S.R. |
| Dx: |
Left Unicompartment Arthroplasty |
Date of surgery: |
9-15-05 |
| Surgeon: |
Kirt Kimball, M.D. |
| History: |
Long history of left knee pain secondary to degenerative joint condition and arthritis affecting the medial compartment. A total knee replacement was not indicated, as the lateral compartment was unaffected by arthritic changes. |
Summary:
- Following the patient’s surgery and hospitalization, Dr. Kirt Kimball ordered a GenUbender machine for the patient to use at home instead of the traditional CPM.
- A GenUbender machine was delivered to the patient’s home on 9-20-05. She was thoroughly instructed in the set up and use of the machine. She was given a written copy of the established protocol. Range of motion measurements were taken and found to 20 - 80 degrees.
- The patient also received home health physical therapy 3 times per week to work on strengthening, gait training and to supervise to GenUbender protocol.
- After 3 weeks of home physical therapy and daily use of the GenUbender, the machine was removed from the patient’s home on 10-11-05. Range of motion measurements were taken and found to 0 - 130 degrees.
