PRP therapy involves concentrating platelets from whole blood through centrifugation to increase growth factor levels and promote healing. Platelets contain growth factors that attract stem cells, promote cell proliferation and healing. While research on platelet growth factors dates back to the 1980s, interest in clinical PRP applications grew due to studies on treating tennis elbow. PRP involves extracting a patient's blood, centrifuging it to separate platelets from plasma, then injecting the concentrated platelets into injured tissues like tendons. Studies support PRP for tennis elbow but not rotator cuff repair. Future research may refine PRP techniques and indications.

2. What is PRP?
PRP is simply whole
blood that is
centrifuged to create
an increased
concentration of
platelets with or
without WBC’s

3. What’s so special about Platelets?
• Platelets contain granules that store
large numbers of “growth factors”
• Alpha granules released (activated)
when platelets aggregate and
adhere to a site of injury or
inflammation
• Listing of other growth factors:
interleukin-1, tumor necrosis
factor, transforming growth factor,
insulin growth factor and more
• It is the activation of platelets and
release of the various growth
factors that makes them special
and is the key to enhancing tissue
repair and healing!

4. Platelet Rich Plasma Biology
What do these Growth Factors Do??
• Chemotaxis
– Directional movement in response to a chemical
stimulus
– Stems cells are attracted to the growth factors and
migrate into the area
• Cell proliferation
– Significant increase in cellular reproduction
activity
• Possibly even a systemc effect
– Performance enhancing?

5. The Primary Growth Factors Role in
Soft Tissue Healing and Repair
• PDGF
– 2 polypeptide chains
– AB, BB and AA types (AB in human platelets)
– Stored in alpha granules in platelets
– Receptors are found in tendon, cartilage, synovium and
elsewhere
• TGF beta
– Also polypeptide, multiple chains, TGF beta-1 most
studied form
– Found in platelets and bone, cartilage
– Also found in macrophages
– Receptors are universal in cells throughout the body

Clinics, Warangal-506002

6. Effect of PDGF on Tissues
• Immediate (within 5 minutes)
– Second messenger stimulation
– Inflammatory response
• Early (30min to 4 hours)
– M-RNA stimulation, protein synthesis
– Chemotaxis (draws cells to the area)
• Late (4-24 hours)
– Fibroblast mitosis

Clinics, Warangal-506002

7. Effect of TGF-Beta on Tissues
• Actually inhibits cell growth
• More of a modulator of cell growth,
differentiation
– Very important in wound repair

Clinics, Warangal-506002

8. Summary of Effect of Platelet
Growth Factors on Tissues
It appears that through a complex series of
biochemical and cellular events, these
growth factors cause a rapid and sustained
increase in the number of fibroblasts in an
area and then through a poorly understood
interaction among factors modulates
cellular activity to cause stem cell
maturation.

9. Breaking News?
So when did all this
information about
platelets get
discovered?
Is this Twitter
Worthy News????

10. AOSSM sponsored Sports Induced
Inflammation Workshop.
Bethesda, Maryland. May 1989.
“Although the cellular events involved in the healing
and repair of musculoskeletal connective tissue
injuries are reasonably well described, the
molecular mechanisms regulating these responses
are incompletely understood. New information,
particularly on the roles of various cytokines and
growth factors in inflammation and wound healing,
however, is continually being published. This
information may ultimately have far reaching
therapeutic implications.”

11. Round Table Discussion on
Clinical uses of PRP
Dr. Steven Arnoczky - moderator.
Orthopedics Today March 2009
“Platelet rich plasma (PRP) is generically defined as an
increase (above baseline) in the concentration of platelets
and their associated growth factors. While the clinical
benefits of PRP in enhancing the healing of
musculoskeletal tissues are only beginning to be
explored, the substantial amount of basic science data
supporting the role of growth factors in enhancing cell
migration, proliferation and matrix synthesis has provided
a compelling rationale for use of PRP in the treatment
and repair of various connective tissue structures.”

• Stem cells
• MSC’s
• Lipocytes
• Bone Marrow

13. Current Clinical Uses of PRP
• Everything and
anything!
• Internet marketing for
host of ailments
• Snake oil of today
“Cures rheumatism,
grows hair, gets rid of
wrinkles, etc., etc.”

14. Current Clinical Uses of PRP
Compelling Rationale!
• Meniscus repair
• Tendonitis (office based
injection)
• Arthritis?
• Ligament surgery?
• Tendon repairs?
• Acute injury?

15. Past Clinical Use in Improving Healing
of Meniscus Repairs Using - Fibrin Clot
• Dr. Warren and Dr. Arnoczky at HSS
• Whole blood, clotted and injected
• Difficult to handle, difficult to inject
• No commercial backing
• Fell out of favor

16. Why the interest in PRP?
Historically there has been interest for a long
time at the research level.
Clinical interest started with an hypothesis by
Mishra et al.
Could the treatment of a common clinical
disorder - lateral epicondylitis be improved
by injecting PRP into the tendon?
03/05/17 16Dr.Shoeb AHMED Ruby Dental
Clinics, Warangal-506002

17. Clinical Model
Lateral Tendinosis
(aka lateral epicondylitis/tennis elbow)
• Common Disorder
– 5 per 1000 pts per year seen in general
practice
• Natural history—
– Highly variable - lack of uniform
response to treatment
• Typically seen over age 35
• Repetitive activities
– Most common cause
– May occur from injury (acutely)

18. Tendinopathy or Tendinosis
Definitions - Histologically
Speaking
–Loss of longitudinal alignment of
collagen fibers
–Hypercellularity with
neovascularization
–-No acute inflammatory cells
–Angiofibroblastic Hyperplasia
(Nirschl)
–Grossly--no longer white but
rather gray

19. Disappointing Effects of Current
Clinical Rx of Inflammation
Oral NSAID’S or
Corticosteroid injection
• interrupts the inflammatory
cycle
• GI intolerance of many oral
meds
• decreases proteoglycan
synthesis
• weakens tendon tissue
• atrophy of subQ fat
• skin discoloration

20. Clinical Application
for Use of PRP
In the Treatment of Tendinopathy - Mishra
•Current clinical investigations being performed in
the treatment of lateral epicondylitis
•Difficult patient mix with some having failed
surgery or multiple cortisone injections
•Part of approval process for FDA certification for
this use
•First step towards insurance co recognition of this
as treatment modality worthy of reimbursement

26. PRP use in RCR
Despite a Compelling Rationale
There have been a handful of good Level I
studies that have shown no benefit in terms of
clinical scores or healing rate when PRP is
used to augment the surgical repair of a
rotator cuff tear.

27. Future of PRP
Expanding role in the treatment of many conditions and
an adjunct to healing in the care of connective and
musculoskeletal tissues.
We have only scratched the surface.
Future use will likely involve staged biochemical
manipulation of the healing and inflammatory
process.
The future is bright but uncertain until more clinical
series are completed.

28. Limitations in the use of PRP
• Efficacy
– Lack of clinical data
• Number of studies being
done
• Indications are being
developed
• Uniformity of prep
– PRP classification
• Insurance recognition
– CMS tracking code
• $$$$$$$ - Evidence based?
