Osteoarthritis “wear and tear” “bone on bone” Pathologic hallmark is focal loss of cartilage
Osteoarthritis symptoms- moderate to severe persistent pain Loss of mobility Decrease of motion Altered activity level Deformity
Osteoarthritis Treatment Goals- Freedom, increase range of motion, improved quality of life
Treatment-osteoarthitis Rehabilitation-PT Restore or improve function through use of exercise, pain relief and educational programs
Treatment-Osteoarthitis Analgesics- NSAIDs, Tylenol injections- steroids, gel injections Weight loss
Treatment-osteoarthritis Unloader brace- Changes alignment of knee, excellent for patients with some deformity
Treatment-osteoarthritis Alternative treatments- Glucosamine Chondroitin sulphate Vit E Tumeric
Surgical options Arthroscopy-does not treat arthritis Indicated only for mechanical symptoms
Surgical treatment Joint Replacement- Goals to reduce pain, increase ADL, increase mobility and function, improve quality of life
Surgical treatment Joint replacement 600,000/year Very predictable- <15 % revision rate 90% patient satisfaction Improves quality of life like CABG
Surgical treatment Osteotomy- Cutting tibia and changing alignment of knee 60% survival at 10 years
Osteotomy
Surgical treatment Partial Knee Replacement- Replacing only the arthritic compartment , usually medial Good survival rate in appropriate patients
Partial knee replacement
Surgical treatment TKR- Replacing the arthritic surfaces with metal and plastic implants Maintain ligaments Maintain muscle and motion
Surgical treatment Complications Infection 1-2% Blood clots 1-2% Instability Limited range of motion Difficulty kneeling
