Lack of Competition Based on Value
Patient choice and competition for patients are powerful
forces to encourage continuous improvement in value
and restructuring of care
Today’s competition in health care is not aligned with
value Financial success of Patient
system participants success
Creating positive-sum competition on value is
fundamental to health care reform

Value = Outcome/ Cost
Value in any field must be
defined around the customer
(e.g., patient), not the supplier
(e.g., providers)
VALUE
*Outcome= Quality (e.g., clinical outcome,
safety) + Service (e.g., satisfaction,
convenience, communication)

I believe that my choice of surgeon will have an
important impact on my outcome. 4.7
There are big differences in the quality of care among
different orthopaedic surgeons. 4.5
I had adequate information to choose the surgeon for
my procedure. 3.3
I found data that helped me understand how this
surgeon compares to other surgeons. 3.2
Who Will Define ‘Quality’ in Orthopaedics?
Requires development of quality measures and
ensures close collaboration with physicians and
other stakeholders regarding the measures used
in the performance program.

Is Hip Arthroscopy Cost-effective for
Femoroacetabular Impingement?
David W. Shearer MD, MPH, Jonathan Kramer BS,
Kevin J. Bozic MD, MBA, Brian T. Feeley MD
CORR 2012
If NO arthritis, may be cost effective or beneficial
With arthritis, probably NOT cost effective unless
there is a benefit delay to a THR for 16 years
The Patient
(Ideal compared to open surgery)
1. Day surgery
2. Reduced pain and
disability
3. Reduced loss of
productivity (work)
4. Reduced limited
mobility
5. Quicker return to self-
care (reduced family
burden), ADLs and
sports

3. Best practices advice
Define the goals of surgery
Relieve pain
Preserve cartilage and labrum
Restore ROM and function

Time away from team
Family, etc.
Best practices advice for hip arthroscopy
Any non-arthritic hip
condition
Some with < Tönnis 1
Expectations match
outcomes
Surgeons expectations
= patients expectations
Reasonable and proven
procedures
Other tips to maximize value to patient, surgeon,
hospital, insurer, government (public health benefits)
1. Correct indications, supported by H&P and imaging
2. Surgeon should know his abilities, and optimize the
surgical environment
3. Hospitals and surgical centers of excellence only
(avoid the occasional hip scope)
4. Insurers should pay a reasonable fee to support
centers of excellence
5. Insurers and Government should rely on members
(not bureaucrats) of AAOS and AANA to determine
appropriate hip surgical procedures

The Problem:
Number of patients needing TJA will continue to grow
Kurtz et al JBJS 2007
600%
Background
Total hip replacement is
one of the most cost-
effective procedures in
all of medicine
Cautioned against overutilization of THA in
young active patients
Described those over 65 yrs as best suited
candidates
By the 2nd decade, considered expanding THA
to much younger and more active pts
10/20/2014

Primary goals
Pain relief
Restoration of Essential Functions
One of the most cost-effective medical interventions for improving
quality of life
Total Hip Arthroplasty
Implant Design
Bearing Surfaces
Surgical Techniques
Lead to improved outcomes
Increased patient satisfaction
Enhanced Implant Durability
Increased patient expectations and demand
Total Hip Arthroplasty
# THAs in the United States
continues to steadily increase
Most rapid rate of growth is in
younger patients

Rating scales for THA
Harris, Merle d’Aubigne developed hip
scores in 1960’s
Consistent with indications at that time,
excellent score required only pain relief,
normal walking, and successful basic
ADLs
In spite of application of procedures
to younger, more active, more
demanding patient population, same
rating scales still utilized
General outcomes, QOL measures
added; substantial ceiling effect
persists
Evidence emerging that all patient
expectations are not being met
43% of patients had ALL of their expectations
fulfilled completely
Absence of any post-operative limp among most
important prognostic factors for satisfaction
10/20/2014
7
Specific values important to patients,
spouses, families, employers not
specifically addressed by current rating
scales:
Return to employment at high level
Return to high level recreation
Return to normal sexual function
National Multi-Center Study Recently Completed
to:
Establish current level of success/
function of modern implants in
returning high demand patients to
crucial activities
Determine if there are any discernible
differences among currently utilized
implants (including THA vs. SRA)
Definitions
Modern implants = uncemented stem + advanced bearing surface
Advanced bearing surface:
Highly cross-linked polyethylene against metal, ceramic, or Oxinium
Ceramic-ceramic
Metal-metal (monoblock, modular, SRA)
High demand patients = age ≤ 60 + high activity level (premorbid UCLA
score ≥ 6)
10/20/2014
8
Multicenter Study: Methods
Collected data through the administration of an unbiased and blinded
telephone questionnaire to evaluate functional outcomes of modern hip
implants at a minimum of one year after surgery.
Included patients from 5 geographically diverse medical centers with
experience using different types of advanced bearing surfaces.

Employment
THA is one of the most commonly performed
surgical procedure in the world
Limited information in the literature to
provide to patients, employers, and insurance
companies about returning to work after THA
Employment is vital component to overall
quality of life in young, active patients

Young-Jo Kim, MD/PhD
Associate Professor of Orthopaedic Surgery
Acetabular Dysplasia
Insufficient acetabular coverage leads to
mechanical instability
Overloaded labrum and acetabular cartilage
at the acetabular edge degenerates and
results in hip PAIN with activity and
OSTEOARTHRITIS
Periacetabular osteotomy reorients the
shallow acetabulum resulting in less PAIN
and POSSIBLE slowing of OA progression

Clinical Outcome after PAO
Survival data using THA as end point
5-10 year 84-90%
Matheney, Kim, and Millis JBJS 2009 91:2113-2123
Troelsen, Elmengaard, Soballe JBJS 2009 91:2169-2179
20 year 60%
Steppacher, Tannast, Ganz, Siebenrock CORR 2008

Predictors of Failure
Higher age
More osteoarthritis, Tonnis grade>1
Poor joint congruency after osteotomy
Severe dysplasia
QOL in PAO patients older than 40
Cohort comparison study
WOMAC and SF-12
assessment
Although PAO resulted in
good QOL, THA was
better.

Cost Effectiveness of PAO
Cost effectiveness primarily a function of
pre-existing OA and longevity after surgery
Tonnis grade I PAO more cost effective
Cost effectiveness of $7856 per quality adjusted life
year
Tonnis grade II PAO still more cost
effective, but
Cost effectiveness of $824 per quality adjusted life
year
Tonnis grade III THA more cost effective

Proper patient selection is key!
Radiographic Assessment of Hip OA
Plain radiographic features
Joint space narrowing
Osteophyte formation
Subchondral cyst formation
Radiographic views
Standing vs supine AP pelvis views
False profile view
Functional view (abduction, flexion, internal rotation
view)

Tönnis Grade of OA
Subjective grading of radiographic OA on AP
pelvis
Grade 0 no arthritis
Grade 1 increased sclerosis of head and
acetabulum, slight narrowing of the joint
space, slight lipping at the joint margins
Tönnis Grade of OA
Grade 2 small cysts in the head or
acetabulum, increasing narrowing of the joint
space, moderate loss of sphericity of head
Grade 3 large cysts in the head or
acetabulum, severe narrowing or obliteration
of the joint space, severe deformity of the
head, necrosis
Difficult to distinguish between grade 0 and 1
Inter-rater reliability can be poor
Joint Space Width Quantitative Measure of
Cartilage Loss
Measure the minimum space between
acetabulum and femoral head in the weight
bearing zone
Usually more reliable measure
JSW > 3 mm considered normal
JSW < 2.5 mm is considered arthritic

Study Design
Prospective cohort study looking at factors
affecting early failure of the joint after PAO
Looked at pre-operative dGEMRIC, patient
factors, radiographic factors
Looked at clinical and radiographic failure as
well as conversion to THR
Results
Multiple stepwise logistic regression
confirmed that dGEMRIC and joint
subluxation are predictors of outcome
independent of age, center-edge angle of
Wiberg, Tönnis grade, and joint congruency.
Final model:
dGEMRIC: likelihood ratio test=9.91, p=0.002
Subluxation: likelihood ratio test=6.33,
p=0.012

Patient Selection for Pelvic Osteotomy
44 year old woman with chronic right hip
pain with activity
Pain in the anterior groin
Pain with activity and night pain

7 years post-op
Conclusion
PAO can be a cost effective solution in
young patients with minimal osteoarthritis
Proper staging of cartilage damage is helpful
in improving the overall outcome after PAO
