Intra-articular Corticosteroids
• Beneficial in KNEE
• Short-duration benefits: 2-4 weeks• Every 3 months ,not effective at 2
years
![Page 12: Non arthroplasty oa knee](https://reader036.fdocuments.net/reader036/viewer/2022082309/554b400fb4c905ff268b4b5d/html5/thumbnails/12.jpg)
• Delayed effect (4 weeks)• Long duration (6 months)• 1-5 weekly injections
Not recommended J Bone Joint Surg Am, 2013 Oct
Intra-Articular Hyaluronic Acid (IAHA)“viscosupplement”
![Page 13: Non arthroplasty oa knee](https://reader036.fdocuments.net/reader036/viewer/2022082309/554b400fb4c905ff268b4b5d/html5/thumbnails/13.jpg)
IAHA: Mechanism of Action
• Increased synovial fluid HA conc.• Increased cartilage
lubrication/elasticity• Chondrocyte proliferation• Decreased inflammatory mediators

Platelet-Rich Plasma in Knee OA
• Kon et al 2010 and Filardo et al 2011 , series n=115• Three 5ml PRP; improved at 6 and 12 months
• Sampson et al 2010 series n=14• PRP at 0/4/8 wks; pain reduction out to 52 weeks in majority
• Wang-Saegusa et al 2011 series n=261• PRP at 0/2/4 wks; improved pain/fxn/QOL to 6 mos w/o AdvEfx
• Sanchez et al. 2008 case/cont• PGRF vs Hyaluronic acid (HA), weekly x3• At 5 weeks, 33% decrease pain w/ PRGF, 10% w/ HA
• Spakova et al 2012 case/cont, n=120• PRP vs HA, weekly x3; At 3 & 6 mo, PRP better WOMAC/VAS
• Kon & Mendelbaum et al 2011 case/cont n=150• LMW HA vs HMW-HA vs PRP at weekly x3• PRP better than HA at 6 mo• Age > 50 and severe OA: PRP = LMW-HA• Age<50 with cartilage lesions, and mild OA: PRP best
• Li & Zhang et al, 2011 RCT n=30• PRP vs HA at 0/3/6 weeks; PRP more effective at 6 mo

Arthroscopic Debridement ??
• “In a controlled trial involving patients with osteoarthritis of the knee, the outcomes after arthroscopic lavage or arthroscopic débridement were no better than those after a placebo procedure”.

Osteotomy
![Page 20: Non arthroplasty oa knee](https://reader036.fdocuments.net/reader036/viewer/2022082309/554b400fb4c905ff268b4b5d/html5/thumbnails/20.jpg)
Dr. Mark Coventry of the Mayo Clinic who first described osteotomy for degenerative arthritis. The original paper published in 1965 continues to be clinically relevant.

HTO-Indications
• Active lifestyle • ≤ 60 yrs• Uni compartment disease • ≤ 10° Fixed flexion deformity• ≥ 90° flexion

Types of OsteotomyCoventry Closing Wedge 1960s
![Page 23: Non arthroplasty oa knee](https://reader036.fdocuments.net/reader036/viewer/2022082309/554b400fb4c905ff268b4b5d/html5/thumbnails/23.jpg)

Disadvantages of Closing Wedge Osteotomy
• Removes bone from metaphysis• Requires fibular osteotomy• Peroneal neuropathy 15%• Lateral tibiofemoral instability 15%• Patella Baja• Increases difficulty of later TKA
![Page 25: Non arthroplasty oa knee](https://reader036.fdocuments.net/reader036/viewer/2022082309/554b400fb4c905ff268b4b5d/html5/thumbnails/25.jpg)
Opening Wedge Osteotomy1990s
Noyes FR, Goebel SX, West J: Opening wedge tibial osteotomy: The 3-triangle method to correct axial alignment and tibial slope. Am J Sports Med 33:378-387, 2005.)
![Page 26: Non arthroplasty oa knee](https://reader036.fdocuments.net/reader036/viewer/2022082309/554b400fb4c905ff268b4b5d/html5/thumbnails/26.jpg)
Advantages of Opening Wedge Osteotomy
• Adds bone to tibial metaphysis• No lateral knee instability• Rare peroneal neuropathy• Later TKA no more difficult than
usual
