The document summarizes research on prolotherapy, which involves injections to repair soft tissues like ligaments and tendons. It discusses definitions of prolotherapy and focuses on dextrose prolotherapy. It provides evidence that prolotherapy is not experimental, as it is taught in postgraduate medical programs and supported by published studies. Several studies on specific conditions like Achilles tendinosis, knee osteoarthritis, and low back pain are summarized, demonstrating safety and efficacy of prolotherapy though some need further research.

2. Sections of Talk
• Definitions and Focus
• Is Prolotherapy Experimental?
• Studies by Topic.
3. Definition of Prolotherapy:
Option One
• Injection to repair or restore function of
soft tissue which includes cartilage,
ligament, tendon, nerve, and supportive
matrix.
• PRP, stem cell, and ozone injection are all
methods of reparative injection and can
reasonably be called prolotherapy.
• For billing purposes connective tissue or
joint prolo should be distinct from Neural
prolo.
4. Definition of Prolotherapy:
Option Two
• Injection to repair soft tissue which
includes cartilage, ligament, tendon,
nerve, and supportive matrix.
• Injection to restore nerve function neural
prolotherapy is best termed Lyftogt
technique.
• For billing purposes connective tissue or
joint prolo should be distinct from Neural
prolo.
5. Focus of This Talk
• Dextrose prolotherapy as data on other
types of injectants is much more limited.
• However, we will consider how other
injectants can be evaluated in similar
ways.
6. Dextrose Prolotherapy Is Not
Experimental Because
• It is taught as an acceptable method
procedure by one or more approved post
graduate programs for the healing arts?
(Univ Wisconsin, specialty college in
AOA), and
• It is based upon sufficient learned
publications supporting the safety and
efficacy? (Level B or higher in multiple
areas)
7. Taught in Department of Family
Medicine at University of Wisconsin
• “Prolotherapy is performed and taught to Family
Medicine residents on a regular basis at the
University of Wisconsin School of Medicine and
Public Health. Residents in this program also
participate in a 2 week hands on CME training
program in prolotherapy in Honduras. This counts
as part of their orthopedic elective time in the
residency.”
Jeffrey J. Patterson, Professor of F.P. at U.W Wisconsin
8. Taught in Continuing Education
Programming By University of
Wisconsin
• “In addition the The University of Wisconsin School
of Medicine and Public health sponsors post
graduate CME programs in prolotherapy through
the UW Department of Continuing Medical
Education. These are held annually on the UW
campus. “
Jeffrey J. Patterson, Professor of Family Practice at U.W Wisconsin

10. U.S. Preventative Service Task Force
Classification of Evidence
• Level I: Well designed RCT (s) with clinical and
statistically significant evidence.
• Level II: Well designed:
II-1 Controlled trials without randomization
II-2 Cohort or case control studies from more
than one center.
II-3 Dramatic result from uncontrolled trial,
Blinded Machine Measure case control
Level III. Substantially flawed RCTs or other controlled
studies. Single well designed cohort or case control
study
11. When SHOULD You Discuss
Prolotherapy With Patients
• A: Good evidence Benefit > Risk
• B: Fair evidence Benefit > Risk
• C. Fair evidence Benefit = Risk
• D. Fair evidence Benefit < Risk
• I. Insufficient , poor quality or conflicting
evidence.

14. Referrals for Prolotherapy Are
Not Just Based on Evidence
• Competition
• Literature ignorance
• Invasiveness
• Artfulness
15. Insurance Coverage Is Not Just Based
on Evidence
• Standardized method. This will
require introduction into medical
schools or repeated RCTs.
• Simple method compatible with
single level payment.
16. Benefit of Insurance Coverage Is Not
Just Based on Evidence
• Option to bill above single level
payment for more complex cases?
(Time based or condition based
approach is too advanced to expect in
a socialist system)
• Insurance company abuse.
17. Achilles Tendinosis (Chronic)
• RCT Nonblinded: #40 (15/14/15), Yelland 2009, 20%
Dextrose + .1 Lido/Ropiv, subcu, weekly, mean 9.5 Rx, 1 Yr

intratendon, 6 wk interval, 5(1-13) Rx, 28 wk(5-73) HRUS
fup, 1-4 Yr symptom fup, 70% data, VAS sport 74%
improvement, HRUS correlation.
• CONCLUSION = Fair evidence of benefit and objective
ultrasound findings but methods needing improvement
in efficacy to exceed therapy standard of care. = B
18. ACL Ligament Laxity
• Case series #18: Reeves 2003, KT-1000 ADD >1, single intraartic
10% Dextrose + .1 Lido + .9 BA in water VS same without 10%
Dextrose. 9 ml Q 2 mo X 3 and then PRN for 3 years. (25%
dextrose given in some injections after year one) 2 dropout (1
disseminated cancer and 1 w/c bound with travel issues), 10/16 no
laxity and sustained at 3 months, pain with walking improved 43%,
subjective swelling improved 63%, ROM by 10.5 degrees total
flexion.
19. ACL Ligament Laxity
• Summary: Single case series but with objective end
point. (KT-1000 measure) Level B/C Safety plus fair
evidence of effectiveness but small study needing
confirmation.
• Option: Repeat with delayed treatment cohort and
blinded machine measure.
• Reeves KD, Hassanein K. Long-term effects of dextrose prolotherapy for anterior cruciate ligament laxity. Altern

groin pain, 92% return to full sport.
21. Adductor Tendinosis
• Summary: Moderate size study with failure of usual
treatment and clear endpoint of unrestricted sport.
Level B Evidence. Safety and good evidence of efficacy.
• Options: Repeat study for stronger B level evidence as
blinding not feasible/ethical. Consider neural therapy
approaches as they are clarified.

dextrose + .4% lido 10 ml over most
tender area, 2 week interval, 2-3 Rx, fup
time not mentioned, marked improvement
in VAS for pain in 30/37.
23. Coccygodynia Pain
• Summary: Level B/C Evidence. Attractive surgery
alternative but small size and fup time not specified.
May have neural effect via large volume.
• Option: Repeat with neural prolo and potentially
enthesis injection as well and more defined followup
timing.

24. Finger Osteoarthritis
• RCT #27 (13 Dextrose/ 14 Lido): Reeves 2000, medial
and lateral injection of ½ ml of either 10% Dextrose + .1
Lido + .9 BA in water VS same without 10% Dextrose.
Q 1 mo X 3. 6 mo fup blinded. Then all received
dextrose through 1 year. 100% data capture to 1 year. 6
month data showed pain with movement significantly
better with dextrose (42% vs 15% p = .027) and flexion
range improved more (+8 vs -8.7 degrees, p =.003)
25. Finger Osteoarthritis
• Summary: Small single RCT. Level A Safety plus fair
evidence of effectiveness. However other classification
is 1B evidence with small high quality RCT with fewer
than 2 consistent RCTs. Discomfort with injection is
drawback to this method.
• Option: Vitamin D study due to pain with injection as an
alternative.

for osteoarthritic thumbs and fingers (DIP, PIP and trapeziometacarpal Joints) : Evidence of clinical efficacy. Jnl
Alt Compl Med 2000;6(4):311-320.
26. Knee Osteoarthritis
• RCT #120: Reeves 2000, single intraartic 10% Dextrose
+ .1 Lido + .9 BA in water VS same without 10%
Dextrose. 9 ml Q 2 mo X 3. 6 mo fup blinded. 6 Month
additional fup for 1 yr. 9 dropouts (5 medial, 4 efficacy[3
lido]). 100% data capture for remaining 111. Pain
improvements not different but ROM and subjective
swelling and buckling episodes were better in the
dextrose group. (Overall Dextrose better with P = .015)
• RCT # ___ UW Study with final results pending.
• Pre and Post Arthroscopy study Argentina in bone on
bone (medial compartment) knees with results pending.
27. Knee Osteoarthritis
• Summary: Level B Evidence. Risks minimal (dextrose
alone). Good clinical response but not level A because
control improved pain enough that lidocaine or benzyl
alcohol or hypotonic solution injection may not be a
control intervention. Needs further confirmation for that
reason.
• Option: Await UW Study and arthroscopy study results.
May repeat without lidocaine vs Saline. (Dextrose has
been found to be analgesic). OR may combine neural
therapy, or alternatively treat with neural prolotherapy
without intraarticular prolo.

week Rx interval, μ7.1 Rx, 96% data capture 1 year and 80% at 2
years, no signif differences with saline but 36%/33% improvement in
pain and 42%/31% improvement in disability scores at 1 year,
sustainable to 2 years.
31. Low Back Pain: Non specific
• Summary: Level B/C Evidence. Fair sized study with
