MY GOAL AS AN INSTRUCTOR

provide a safe participant oriented environment

Treatment of Knee OA

• Pt education

• Reach ideal body weight in those who are overweight

– Weight loss can result in significant decrease in symptoms

• Alter lifestyle behaviors, eg, overuse syndromes

• Mostly palliative to decrease pain, leading ideally to improved health-related quality of life

.

Treatment of Knee OA

• Analgesics/anti-inflammatory therapies

• Assistive devices to “unload” joints

• Cognitive behavior therapy

• Physical therapy and exercise therapy

• No proven structure-modifying therapies

• Recent data regarding metalloproteinase inhibitors suggests some benefit in patients with progressive disease

Principles for Knee Osteoarthritis management

• National guidelines from AAOS, ACR, and AGS1,3,4

–Exercise, weight loss relieve symptoms and

maintain function

–NSAIDs and tramadol preferred for most

patients

–Acetaminophen may be preferred for older

patients because of better safety profile

Benefits of local corticosteroid injections

• Reduce inflammation

• Rapid reduction in pain

• Improve range of motion

• Prevent contracture

*In inflammatory conditions chondroprotective and may prevent or inhibit erosion of cartilage and bone

Benefits of aspirations and intra-articular steroid injection include:

Steroid Duration/Potency Dose/site

Hydrocortisone acetate Low/Short 10-25 mg for soft tissue and small

joints/ 50 mg for large joints

Methylprednisolone acetate

(Depo Medrol) Intermediate/Intermediate

2-10 mg for soft tissue and small

joints / 10-80 mg for large joints

Triamcinolone acetonide

(Aristocort, Kenalog)

Triamcinilone

Hexacetonide (Aristospan)

Intermediate/Intermediate

Long/High

2-10 mg for soft tissue and small

joints / 10-80 mg for large joints

Dexamethasone sodium

phosphate (Decadron) High/Long

0.5-3.0 mg for soft tissue and

small joints / 2-4 mg for large

joints

Betamethasone (Celestone

Soluspan) High/Long

1-3 mg for soft tissue and small

joints, 2-6 mg for large joints

Mechanism of action:Corticosteroid Injections

Purported to be a local anti-inflammatory?

Steroids locally in the joint have effects on:

edema

lymphocytes

macrophages

mast cells

Side Effects:Corticosteroid Injections

Infection (1 in 50,000 injections)¹

Post injection flare (2% crystal induced synovitis)¹

Skin hypopigmentation, subcutaneous atrophy¹

Vasovagal syncope (procedure related)¹

Tendon rupture (rare)¹

Osteonecrosis (rare)¹1. West, S Rheumatology Secrets 2rd edition 2002

Relative contraindications to injections

• superficial infection or broken skin

• unstable coagulopathy

• prosthetic joint (hemiarthroplasty can be injected)

Aspiration should be performed if

sepsis is suspected

Hyaluronic Acid Injections

Synovial Fluid

Acts as lubricant

Serves as shock absorber

Relieves pain

Retards inflammation

May support the synthesis of normal hyaluronic acid

Why is HA usedto treat pain in O/A?

Cannot take NSAIDs

Will not take corticosteroid injections

Too young for total knee replacement

Not ready for total knee replacement

“nothing else has worked”

Early chondral problems in young patients

Common

injection sites

for corticosteroid injections

•Shoulder

•Trochanteric bursa

•Knee

•Trigger points

Uncommon

sites•HIP (guided)

•SIJ (guided)

•Achilles Tendon

•Infra-patellar Bursa

•TMJ

•Flexor Tendons

•Small joints of hands or feet

Tips for good procedures I•Beginners’ main problem;

Finding the right spot.

•Anatomy picture

for joints and think of referred patterns

Trigger points:

In general stick the needle where it hurts.

•Difficult to cause real

Damage except side of neck

or chest wall.

length vs. gauge

•The longer and thinner the needle,

The more flexible

•The shorter and larger the bore,

The more rigid

Larger needles for larger joints

Smaller needles for smaller joints

Needle choices

Tips for good procedures II

•Relaxed Patient

•Relaxed Operator

Tips for good procedures III

•Right hand injects

•Left hand supports

•Patient is foundation

•Left hand must be

anchored to patient

Tips for good procedures IV

•Pain caused by

rapid tissue invasion

•Introduce needle slowly

•Use smallest needle

possible

•Use smallest injectate

volume possible

•Pain should be no worse

than venipuncture
