Platelet Rich Plasma (PRP) injections for muscle, ligament tendon, cartilage injuries
Blood delivery into Centrifuge system
Centrifuge system will separate the platelet rich plasma from red blood cells and white blood cells

Knee PRP injection technique
Autologous Conditoned Plasma (ACP) PRP Injections
Technique
Prime double syringe
21G Butterfly needle - draw 15 cc blood. No need for citrate if injected w/in 30 mins
Place syringe red cap into centrifuge w/ counterbalance (saline filled syringe)
Spin @ 1500 rpm x 5 mins
Place index fingers under clear wings of outer syringe & use thumbs to depress red wings of inner syringe to draw the plasma into inner syringe.
Insert 22g needle & inject

Intra-articular Autologous Conditioned Plasma Injections Provide Safe and Efficacious Treatment for Knee Osteoarthritis: An FDA-Sanctioned, Randomized, Double-blind, Placebo-controlled Clinical Trial
Patrick A Smith. Am J Sports Med. 2016 April
Conclusion: ACP is safe & provides quantifiable benefits for pain relief & functional improvement w/ regard to knee OA. No adverse events were reported for ACP administration. After 1 year, WOMAC scores for ACP subjects had improved by 78% from baseline score compared to only 7% for placebo control group had improved.

Ultrasound guided PRP (platelet rich plasma) injections
Correlation of the site of pathology on MRI
Meta-analysis of 18 studies
Primary outcome = change in pain intensity. Leukocyte rich prp better than leukocyte poor prp
Indications: tennis elbow, patella tendonitis, rotator cuff tendinopathy, achilles tendinopathy.
Recommendations: ultrasound guided single prp injection into tendon with 2 mm local anesthetic superficial to tendon using 6 pass peppering dry needling

Randomized Controlled Trial
Platelet rich plasma (PRP) in patients with partial thickness rotator cuff tears or tendinopathy leads to significantly improved short term pain relief & function compared with corticosteroid injection: a double blind randomized controlled trial.
Cory A Kwong et al. Arthroscopy. 2021 Feb.
Conclusions: Patients with PTRCTs or tendinopathy experienced clinical improvement in pain & patient-reported outcome scores after both ultrasound-guided cortisone & PRP injections. Patients who received PRP obtained superior improvement in pain & function at short-term follow-up (3 months). There was no sustained benefit of PRP over cortisone at longer-term follow-up (12 months).
