Osteoarthritis

“A Big Problem”

More than 40 Million Americans have arthritis (joint inflammation)

27 Million people suffer from Osteoarthritis

40 million by 2020

3

Most of us by our 60s & 70s

More women than men after 50

All races equally

Burden of Disease

475,000 Knee Replacements performed annually

Causes

Primary Osteoarthritis (Most Common)

Result of aging

Decreased ability of cartilage to repair itself

Ligaments supporting joints weaken

11

ObesityJoint Injury

Surgery

Congenital abnormal joints

Gout

Causes

Secondary Osteoarthritis

12

Effect of Weight Loss“Take home point”

For each pound of weight loss 4 pound reduction in the forces hitting the knee while walking.

“Less weight, Less load on the knee”

Arthritis and Rheumatism, July 2005

13

University of North CarolinaStudy

“Almost 50% of all U.S. adults

and nearly 66% of obese adults will

develop painful arthritis by the age

of 85”

Osteoporosis

15

Osteoporosis

Loss of Bone Density

16

Symptoms of arthritis

Pain in affected joints

Pain worse with prolonged use

Stiffness after periods of inactivity

Grating or “Catching” sensation with movement

17

Diagnosis

History

Physical Exam

Blood Test- to rule out other diseases

25

Medication- NSAIDs

NSAIDs are nonsteroidal anti-inflammatory drugs

Aspirin

Ibuprofen

Naproxen

26

Vitamins & Nutritional Supplements

Glucosamine / Chondroitin Sulfate

Some positive results for moderate to advance arthritis

Recently, the American Academy of Orthopedic Surgeons

recommended against its use for patients with

osteoarthritis of the knee (Dec, 2008)

Fish Oil (Omega-3 Fatty Acids)

Diet rich in Fruits and Vegetables

Injections

Cortisone (steroid)

Visco-Supplementation (Synvisc One,Orthovisc, Hyalgan, Supartz, Euflexxa)

29

Joint Protection- Daily Exercise

1.Daily range of motion exercise (Stretching)

2.Strengthening exercises every other day

3.Endurance exercises three times per week

30

Exercise Dos

Talk to your doctor first

Consider athletic trainer or physical therapist

31

Braces

Sleeves neoprene

improve balance?

local warmth

control swelling

high compliance

32

Braces

Unloaders “unload” or take pressure of the arthritic side of knee

decrease pain

improve walking tolerance

poor compliance

expensive

33

External Support Aids

“Unloads” the joint

34

When all else fails

to improve pain………..

35

Surgery“Top of the Ladder”

36

Asking Questions About Surgery

Alternatives

Benefits and for how long?

Risks?

What is procedure called?

How is it done?

Results?

Return to “normal” activity?

37

Surgical Options-Arthroscopy

Mini incisions

Outpatient

38

Arthroscopy – Debridement(Shaving of articular Cartilage (“tread”)

A means of “smoothing” the coating cartilage

In conjunction to treating meniscus tears

Not designed for treatment of arthritis alone

39

Arthroscopy – MicrofractureKnee and Shoulder

small awl used to make holes in bone

promote re-growth of cartilage

40

Arthroscopy – “OATS” Procedure

transfer of healthy “tread” to “bald” area

41

Duke University Medical CenterStudy

Hip Replacement Surgery

“Seniors with arthritis who undergo Hip Replacement are twice as likely to show improvements in functioning and ability to care for themselves”

(no age limit on the benefits!!)

50

New Technologies

51

Laboratory

Recombinant Gene Therapy (synthesize the growth factors which produce new cartilage)

Specific Growth Factors promote cartilage (tread) maintenance and repair

May limit the progression of arthritis

Platelet Rich Plasma (PRP)

52

Recent discovery of a natural occurring molecule in the body that can counter the progression of arthritis

Genes and Development

53

Traditional TKA vs. High Flex TKA

Designed to safely accommodate flexionup to 125

Designed to safely accommodate flexionup to 155

New Implant Designs

54

Gender Specific Knee Implant

Women have a different shaped knee joint

New Implant Designs

55

Patient Specific Instrumentation

MRI or CT based technology

3D model created of knee

Surgery Planning

Customized pin guides or cutting blocks

56

Patient Specific Instrumentation

57

Mini-Incision Surgery (Knees)

58

Complications

Mini-Incision Surgery for the knee reduces recovery time but increases wound healing problems.

Clinical Orthopedics and Related Research

Mini-Incision and alternative approaches for the hip---controversial!!!!

59

Consumer Beware

Bozic K J, et al. Impact of direct to consumer advertising on physician attitudes and behavior in orthopedic surgery American Academy of Orthopedic Surgeons

**Poll of 737 hip and knee surgeons

**Over 75% of surgeons reported that direct-to-consumer (DTC) advertising

negatively impacted their practice and the relationship with patients. **Ads presented a skewed view of procedures and devices by

exaggerating the benefits and down playing risks.

**(Patients) were not more educated about the risks and benefits, not more educated about the alternatives, not more educated about the costs and that they were less open to alternatives after reading or viewing direct-to-consumer advertisements
