U W H e a lt h S p o r t s R e h a b i l i t a t i o nPlatelet-Rich Plasma RehabilitationGuidelinesWhat is Tendinopathy?Tendons are strong bands of connectivetissue comprised primarily of asubstance called collagen. Mechanically,tendons connect muscle to boneand transmit the force to generatemovement. Muscle and tendon injuriesaccount for a significant percentage ofthe over 100 million physician visitsin the US per year and this numberwill continue to rise as our populationages and remains active1. Previously,tendon injuries and disorders werealmost always considered tendonitis.Tendonitis is an inflammatory process,but recent research has shown that mostof the more chronic tendon problems donot have any inflammatory cells. Theprimary problem in these cases appearsto be a breakdown of the structuralproperties of the tendon collagen. Thusthe correct terminology for this problemis tendinopathy, as opposed to tendonitis.Tendinopathy results from overstressinga tendon. This can be from a singularacute bout of activity, or more often,from repetitive and sustained stressesover many months or even years. Itis possible for different areas of thetendon to be in different stages ofinjury or disorder2. Tendinopathy canultimately lead to chronic degradationof the tendon, and rarely, to the pointof tearing or rupture. There are manycurrent treatment options for thiscondition including, but not limited to,rest, anti-inflammatory medications(e.g., ibuprofen, naproxen), steroidinjections, physical therapy, shockwave therapy, dry needling and surgery.Recent advancements in regenerative(restoration and growth) medicine haveled to the development of platelet-richplasma (PRP) injections as a viabletreatment for various tendinopathies.What is Platelet-RichPlasma (PRP)?PRP is the concentration of plateletsderived from the plasma portion ofone’s own blood3. While platelets arewidely known to play a large rolein clotting processes, their use intreatment of tendon disease is dueto their abundance of enzymes andgrowth factors related to the healingprocess4,5. Tendons have a poor bloodsupply, meaning it is difficult for thesetissues to receive the nutrients needed tostimulate repair1,4,6. An injection of PRPto the injured site provides the tendontissue with healing growth factors thatare otherwise difficult for the bodyto deliver because of the poor bloodsupply. Similar mechanisms have beentheorized for treatment of ligamentinjuries such as medial collateralligament sprains of the knee or cartilagedeterioration, such as osteoarthritis ofthe knee7. The injection can also restarta healing inflammatory process, whichis why patients are often given initialactivity restrictions. Subsequent referralsto physical therapy are often made sothat patients may be taught to loadthe tissue in an appropriate fashion torebuild strength and flexibility.What does the PRPprocedure involve?PRP begins by collecting blood fromthe individual, usually by using asyringe and needle at the arm, similarto a clinic laboratory blood draw. Theamount of blood needed is determinedby the size of the area to be treatedand the concentration of plateletsdesired3. The blood is then placed ina centrifuge where the rapid spinningprocess separates the blood into 3components—the plasma or waterportion of the blood, the PRP layer,and the cellular layer containing redand white blood cells. The PRP layer isthen available for use in the clinic. Afterapplying a local anesthetic (numbingmedicine) to the site of the injection,the PRP is injected into the injuredtissue. Sometimes the injection isperformed in the radiology departmentso that the radiologist physicianmay view the area under ultrasoundguidance to ensure accurate placementof the injection. The patient is educatedabout activity restrictions and is oftengiven devices that limit the amount ofmovement at the area for the next fewdays. The patient is encouraged to restthe area for a few weeks, avoiding anyvigorous or strenuous activities, beforeThe health care team forthe UW Badgers and proudsponsor of UW Athletics6 2 1 S c i e n c e D r i v e M a d i s o n , W I 5 3 7 1 1 u ws p o r t sm e d i c i n e . o r g

After the early phases,strengthening and neuromuscularcontrol exercises are emphasizedthroughout the affected extremity. In thefinal stages of rehabilitation, the focuswill be on progressive dynamic extremitycontrol and stability during sport specificmovements, such as change of directionand rotational movements.Do I need to do physicaltherapy and rehabilitationafter PRP?A quality post-procedure rehabilitationprogram helps facilitate a successfuloutcome.

General time frames aregiven for reference to the average, butindividual patients will progress atdifferent rates depending on their age,associated injuries, pre-injury healthstatus, rehabilitation compliance andinjury severity. These guidelines arepresented in reference to tendon-relatedprocedures, but general guidelinesand concepts apply with treatmentof ligamentous, joint, and musclepathologies.PRP Process:ABA: Collection of your own blood,B: Utilizing the centrifuge to separate the plateletsand growth factors from the blood,C: The separation of components into 2 vials,D: the injection of the platelet rich plasma to theaffected area.C2D6 2 1 S c i e n c e D r i v e M a d i s o n , W I 5 3 7 1 1 u ws p o r t sm e d i c i n e . o r g

This will be described for you at your physician clinic visit. Lower body exercise for upper body procedures and upper body exercise for lowerbody procedures are allowed.
