![Page 16: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/16.jpg)
Glucosamine & Chondroitin
• Balance of evidence from high-quality trials has shown little to no evidence of clinically meaningful benefit
• Statistically significant improvement in pain scores in studies with < 6 months of follow-up from mostly low-quality trials.

Q : Clinical case
62 year old women with bilateral grade IV OA and background of CAD / CCF(NYHA IV) and borderline renal dysfunction ( Creatinine :1.9) is suffering with severe knee pain what is your approach
1. TKR 2. I/A steroid injection 3. Analgesics like PCM , Glucosamine + Chondroitin
![Page 21: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/21.jpg)
Answer
• I/A steroid injections
![Page 22: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/22.jpg)
![Page 23: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/23.jpg)
Intraarticular glucocorticoids
• Moderate to severe pain affecting one or a few joints, not adequately relieved by oral drugs.
• Monoarticular or oligoarticular inflammatory OA in whom NSAIDs are contraindicated
![Page 24: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/24.jpg)
Opioid analgesics
• Moderate to severe pain in whom other interventions have failed
• Tramadol (50 to 100 mg max of q6h) alone or in combination with acetaminophen
• Oxycodone - short-term use in patients with acute exacerbations of pain
![Page 25: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/25.jpg)
To summarise
• PCM – still a safe drug in less , 2gms/day • NSAID – use judiciously • Topical NSAID – very effective • Glucosamine + chondroitin – data emerging as
effective • IA steroid can be used for short term pain
relief • Guidelines /recommendations may change

Question 2
Decrease in 5 kg body weight reduces the risk of OA knee by
1. 50%2. 40%3. 30%4. 20%
![Page 62: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/62.jpg)
Answer
Decrease in 5 kg body weight reduces the risk of OA knee by
1. 50%
![Page 63: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/63.jpg)
• Increased body wt. is associated with OA knee• Duration of obesity plays a cumulative role• Women is more in risk • Secretes adipokines from adipose tissue
Exercise – Quadriceps weakness, reduction in body fat, increased physical activitiesDietary Changes – Fat & Caloric restriction
4. WEIGHT LOSS(Decrease in wt by 5kg substantially reduces the risk of OA by 50% )
![Page 64: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/64.jpg)

6.PHYSICAL THERAPY , ROM EXERCISE MODALITIES: SURGE FARADIC STIMULATION, TENS, IFT, UST(Restricted)TRACTION: Controvertial
Target the factors which leads to disabilities
• Flexibility –ROM deficits - extension lag – articular changes, shorting of myotendinous structures, joint stiffness• Shorter muscle has biomechanical disadvantage for generating
forces – so stretching is essential prior to exercise• ROM – important functional activity (knee flexion required)
70° for walking83° for climbing stairs93° for getting up from a chair

55 years old lady with severe varus deformity of both knees, walks with
difficulty with walker support ; X-ray - Severe osteoporosis, Gr IV OA
changes, Femoral and tibial varus
1) Conservative treatment2) Corrective osteotomy of femur and tibia3) Bilateral TKR – Staged (gap of one week)4) Bilateral TKR – single stage
![Page 109: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/109.jpg)
4) Bilateral TKR – single stage
• Single stage – Many advantages– Single anesthesia and OT visit– Cost effective– Safe without added risk of complications– Very effective in severe deformities
• Chance of complications highest if second surgery is done during first two weeks
• Staged TKR - at least a gap of 6 months

Most common early complications in post Total Knee Replacement
1) Infection2) DVT leading to Pulmonary embolism3) Neurovascular Injury4) Acute Renal Failure
![Page 115: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/115.jpg)
2) DVT leading to Pulmonary embolism
• Thirty-Day Postoperative Complications and Mortality Following Total Knee Arthroplasty Incidence and Risk Factors Among a National Sample of 15,321 Patients Philip J. Belmont et al JBJS 2014
Infection=0.30%, DVT= 0.78%, NV injury=0.10%, ARF=0.10%
• Lack of registry data from India• In India, Infection has to be kept in mind

Most common indication for Revision TKR
1) Infection2) Aseptic loosening3) Dislocation4) Periprosthetic fracture
![Page 119: PANEL DISCUSSION : OSTEOARTHRITIS STATE OF THE ART IN 2016 - Dr Darshan Singh Bhakuni](https://reader031.vdocuments.us/reader031/viewer/2022030214/58997f871a28abb97c8b4e27/html5/thumbnails/119.jpg)
2) Aseptic loosening
15 year follow-up of 32476 TKR in Norwegian Arthroplasty Register) Mona et al 10 June 2015• Loosening = 28%• Infection = 21%• Dislocation = 20%• Pain = 6%• Others = 25%

CONCLUSION
• Corrective osteotomy has a great role in middle aged patients with early arthritis and deformity
• Joint replacement surgery greatly improves quality of life in elderly
• 15-yr survival rate of implant is 90%• Aseptic loosening is leading cause of revision
TKR.
