What is Osteoarthritis Knee ?
OA is NON - INFLAMMATORY joint disease
characterized by
Degeneration of articular cartilage
Hypertrophy of bone margins
Changes in synovial membrane

Primary Osteoarthritis : Most Common
• Thought to be result of aging
• Decreased ability of cartilage to repair
itself
• Ligaments and muscle supporting joint
weakened
![Page 6: Dr (Prof.) Anil Arora - Global Ortho Osteoarthritis Knee Management Dr... · Dr (Prof.) Anil Arora MS (Orth) DNB (Orth) Dip SIROT FAPOA (Korea), FIGOF (Germany), FJOA (Japan) Computer](https://reader030.fdocuments.net/reader030/viewer/2022040717/5e240110d6f7927df7405596/html5/thumbnails/6.jpg)
Secondary Osteoarthritis
• Obesity
• Trauma
• Surgery
• Abnormal joints
• Gout
• Diabetes
• Hormone disorders
![Page 7: Dr (Prof.) Anil Arora - Global Ortho Osteoarthritis Knee Management Dr... · Dr (Prof.) Anil Arora MS (Orth) DNB (Orth) Dip SIROT FAPOA (Korea), FIGOF (Germany), FJOA (Japan) Computer](https://reader030.fdocuments.net/reader030/viewer/2022040717/5e240110d6f7927df7405596/html5/thumbnails/7.jpg)
Symptoms
1. Pain at the start of activity that gets better “warms up
over time”
2. Progressive pain with activities
3. Loss of motion, muscle weakness
4. “Crunching” sensation in the knee
5. Over the time deformity can occur in the knee

Diagnosis
• Physical Examination
• X- Ray
• Blood Test to rule out other diseases

OA – Management Principles
• Slow progression over many years - Cannot
be cured
• Treatment directed at symptoms and
slowing progress of the condition
• Goals:
• Decrease pain
• Maintain / Improve range of motion
• Maintain / Improve muscle strength

Stimulate production of cartilage components
and allow rebuilding of damaged cartilage.
1. Glucosamine can increase mucopolysaccharide and
collagen synthesis in fibroblast tissue.
2. Glucosamine also appears to activate core protein
synthesis in human chondrocytes
