• The knee joint is protected in front by the patella
• Meniscus - acts as a shock absorber
• Articular cartilage allows the surfaces of the knee to glide over each other without damaging the surface

• About 7 crore Indians are suffering from knee related problems
• Evidence suggests that women have a higher incidence of OA than men, and overall have an incidence of 2.95 per 1000 population, compared with 1.71 per 1000 population in men

Why is this problem more prevalent in India
• Squatting / Ground sitting habits• Climbing stairs• Indian Toilets• Obesity• Complicated patients• Heredity
Can we prevent Osteoarthritis

Intra-articular
Steroids
• Indicated when knee is inflamed
• Confirm intra-articular placement by draining effusion, then injection
• Wide variation in responses
![Page 23: Total hip replacement in jaipur](https://reader033.vdocuments.mx/reader033/viewer/2022042608/55c3a3cfbb61eb42338b462f/html5/thumbnails/23.jpg)
Viscosupplementation
• Replaces pathologic synovial fluid
• Supplements elasticity and viscosity
• Reduces pain and improves mobility

How do we know that the patient needs surgery ?
• Regular pain needing medication
• Deformity of the knee, crepitus in knee
• Night pain, getting up pain
• Altered social or family life due to pain

Total Knee Replacement
• The ultimate solution for OA of knee is to replace the worn-out parts of the knee with an artificial joint
• The prosthesis that is used is made up of plastic and metal and is placed on the joint surface of each bone
• This surgery has been widely used for many years with excellent results especially for knees

• Day 2 Walking (with aids)
• Day 4/5 Stair climbing
• Day 5-7 Home (with 2 walking sticks)

![Page 41: Total hip replacement in jaipur](https://reader033.vdocuments.mx/reader033/viewer/2022042608/55c3a3cfbb61eb42338b462f/html5/thumbnails/41.jpg)
Benefits of TKR
• TKR can relieve pain that doesn't respond
to other treatment options
• Pain reduction in 90 to 95% of the patients
• Reduced stiffness and improved joint
movement
• Increased walking ability
• Improved alignment of deformed joints
![Page 42: Total hip replacement in jaipur](https://reader033.vdocuments.mx/reader033/viewer/2022042608/55c3a3cfbb61eb42338b462f/html5/thumbnails/42.jpg)
Myths
• Hip replacement works but knee replacement doesn’t
• Knee replacements are still experimental
• Knee replacements only last 8-10 years may be 15 years maximum
• I am too fat - my implants might break
![Page 43: Total hip replacement in jaipur](https://reader033.vdocuments.mx/reader033/viewer/2022042608/55c3a3cfbb61eb42338b462f/html5/thumbnails/43.jpg)
• TKR surgery is too costly
• TKR is not successful
• After TKR, I have to be bedridden for 3 months
• A total knee replacement implies that everything about the joint is being replaced
