WHAT IS REVIVAL PRP®?
REVIVAL PRP® is an Advanced Separator Gel based, easy to use, sterile system that is used to prepare PRP in a safe and effective manner to accelerate the body’s own natural healing process.
PRP is used in various medical applications including tissue enhancement, tissue and cell regeneration, rejuvenation, reconstruction and for general healing and repair.
PRP is indicated for the following conditions:
- ACL rupture
- Chronic and surgical wounds
- Supraspinatus tendinopathy
- Fractures, bone defects and cavities
- Chronic equine laminitis
- Suspensory ligament lesions
- Osteoarthritis and degenerative joint disease

COMMON CONDITIONS IN CANINE, FELINE AND EQUINE SPECIES
As an animal ages or engages in various activities, they are at risk for developing various degenerative joint diseases (DJD), tendinopathies and/or suffering from injuries that may develop into chronic wounds. Some common conditions that they may suffer from are:
Supraspinatus tendinopathy (ST) is characterized by degeneration of the tendon fibers and occurs in young to middle-aged, large breed dogs with no gender predilection (Ho et al 2015) and is a common cause of forelimb lameness in dogs. The cause of ST is thought to be repeated strain and overuse from chronic repetitive activity, with a failure of adequate remodeling (Canapp Jr et al 2016). Extreme and rapid hyperflexion of the shoulder is likely the cause of tear or damage to the supraspinatus tendon.
Dogs are typically non-responsive to traditional treatments such as rest and NSAIDs, and additional reported treatment options such as rehabilitation therapy and surgery may not always be successful.
Following resolution of lameness, there is a lifelong increased susceptibility to re-injury due to the reduced strength of fibrotic scar tissue compared to the original tendon (Ho et al 2015).
Open wounds in dogs can occur from a number of different causes. Abrasions or scrapes can occur when the superficial skin layers are damaged. This will cause minor inflammation, some surface bleeding and may cause bruising. Abrasions can occur from an animal biting at their skin, jumping over or digging under fences, fighting or being dragged across a rough surface.
Lacerations are when an animal’s skin has been cut or torn open. Some lacerations will have clean, smooth edges or they may have jagged edges. Some lacerations will affect multiple layers of tissue depending on what caused the actual laceration. Puncture wounds or bite wounds occur when an object or tooth pierces the skin and leaves a small hole in the surface.
The hole will most likely affect multiple layers of tissue and is most susceptible to bacterial infections. Puncture wounds can easily become abscessed, creating a bigger medical emergency for your client’s pet.
The flexor tendons of horses’ lower limbs are important weight-bearing structures at rest and during locomotion. The anatomic arrangement of tendons and joints in the lower limb provides an efficient transfer of muscular energy for rapid locomotion. Of the two flexor tendons, the superficial digital flexor tendon (SDFT) is more commonly injured than the deep digital flexor tendon (DDFT). The SDFT provides a spring-like store of energy in the galloping horse and is subject to strains close to its mechanical limits, making it susceptible to overstrain injuries. Tendon damage may occur as a result of either overstrain of the tendon or a traumatic penetrating injury (O’Sullivan 2007).
It appears that the SDFT matures early, after which time it has limited ability to adapt to stress and undergoes progressive degeneration (Dowling et al 2000). Tendinopathy of the superficial digital flexor tendon (SDFT) is a common injury in Thoroughbred racehorses and other horse breeds and is regarded as a career limiting disease. Clinical injury is mostly strain induced and characterized by chronic degeneration after repetitive microtrauma in sport horses. Tendinopathy may also be caused by a single external percutaneous trauma, such as a kick (Geburek et al 2016)
Degenerative Joint Disease (DJD) refers to arthritis or osteoarthritis, which is the result of the gradual deterioration of the articular cartilage within one or more the joints. This smooth resilient cartilage degenerates, becoming brittle over time. With severe DJD, the degenerated cartilage may actually split away from the bone and become loose within the joint. DJD can follow a number of joint diseases, including infection, and may develop after bone or joint injury or surgery.
Obese animals are more likely to develop DJD, as a direct result of the mechanical stress that excess weight puts on the joints. Although DJD is not usually an inflammatory disease, mild inflammation plays a part in causing clinical signs. When the cartilage cells become damaged, they release substances that result in inflammation, causing pain and further damage to the cartilage. Thus, once DJD begins, it can become a vicious cycle. Most of the damage caused by DJD is irreversible.
WHAT IS PRP?
Platelet Rich Plasma (PRP) is a portion of the animal’s own blood plasma that is concentrated in platelets and growth factors. These are critical in triggering the body’s regenerative mechanisms.
The most basic method to prepare PRP is through centrifugation. The animal’s blood is drawn and centrifuged at a specific speed until it is separated into 3 layers: Platelet Poor Plasma (PPP), Buffy Coat/Platelet Rich Plasma (PRP) and red blood cells.
REVIVAL PRP’s Advanced Separator Gel sits in between the platelet-rich plasma and the red blood cells to ensure that the physician obtains a plasma preparation that is free from any red blood cells. Red blood cell contamination may provoke an inflammatory effect which can affect healing.
Depending on the application, calcium chloride is added to form a fibrin clot, which this then applied to the affected area.
The platelets undergo degranulation to release Growth Factors (GFs) with healing properties. The plasma contains cytokines, thrombin, and other GFs with inherent biological and adhesive properties.

APPLICATIONS OF PRP IN DIFFERENT THERAPEUTIC AREAS
PRP has many different applications over a wide range of therapeutic areas such as Sports and Orthopedics, Dental, Cosmetic Surgery, Esthetics and Dermatology, General Surgery , Chronic Wounds, and Ophthalmology
Athletes of all competition levels are early adopters of novel treatment methods. They are driven to find less invasive methods of injury management and faster means of returning to their sports.
Ligament, muscle and tendon tears are often slow to heal due to inadequate blood supply to these areas. Although PRP can be injected on any muscle or tendon. The following areas are the most common sites:
- Shoulder (rotator cuff)
- Elbow (Lateral or medial Epicondylitis; aka tennis or golfer’s elbow)
- Knee (patellar tendon; aka Jumper’s knee)
- Ankle (Achilles Tendon)
PRP can also be used during surgery to augment healing for ACL reconstruction and rotator cuff repair.
Connective tissues such as ligaments and tendons heal by filling in with scar tissue, which in turn, doesn’t support the pressure of large loads effectively and increases the risk of re-injury. Chronic tendon injuries are related to degeneration of the tendon tissue. Traditional forms of therapy do not necessarily improve the tendon’s ability to create new tissue and heal in the same way PRP does.
Platelets release bioactive proteins and growth factors which enhance tissue regeneration and healing. New tendon cells called tenocytes start to develop in the treated area. Cartilage cells called chondrocytes form when PRP is injected into damaged cartilage. There is also an increase in the number of growth factors in the treated area as well as a build-up of Type 1 collagen fibers, which constitute the base structure of tendon tissue. PRP has been demonstrated to shorten recovery time, decrease pain and improve performance in the injured area
- Many high-profile athletes are also taking advantage of the benefits that PRP offers:
- Kobe Bryant of the LA Lakers received more than three treatments on his knee in the past few years and was able to make a full comeback after serious injury
- Alex Rodrigues of the New York Yankees received multiple PRP treatments for both his left shoulder and right knee
- Peyton Manning (quarterback of the Denver Broncos) had several treatments to help repair ligaments, tissues and alleviate pain in his neck
- Tiger Woods received PRP treatments for his Achilles tendon and both knees after a knee surgery to repair injury.

Some common orthopedic indications for which PRP is used are listed below:
- Tendinopathies (refers to a degenerative condition of tendons characterized by the chronic loss of collagen, stability, strength and tissue integrity possibly caused by natural aging, injury, repetitive stress, and/or neural, vascular and hormonal inputs)
- Ligament Sprains
- Muscle Strains
- Joints (i.e. osteoarthritis; a chronic degenerative disease of hyaline cartilage)
PRP can be effective for many cases of osteoarthritis as repairing the damage has posed a great challenge due to its regenerative limitations. Platelets and other elements within the blood help tendons and ligaments heal by stimulating a repair and growth response that accelerates the process of developing new tissue. However, the tendons and ligaments do not receive a rich blood supply containing these factors which is why they often take a significant amount of time to heal. PRP stimulates healing of cartilage and reduces pain and disability by delivering these factors directly to the site of injury. Areas of treatment can include knee, hip, shoulder and ankle.
With age, the cartilage lining the joints can shrink and wear thin causing friction between the bones. Bone spurs and inflammation can gradually enlarge the joint leading to the pain and dysfunction of arthritis.
Damages to the cartilage have been treated by cortisone and HA injections, micro fracture, debridement and grafting procedures. The results obtained by these techniques are so far unsatisfactory and in most cases, result in the formation of fibrous connective tissue with minimal mechanical strength at the affected area.
Not only does PRP stimulate cellular activity and the process of regeneration and repair, it also improves bone and cartilage recovery, as well as reduce inflammation and pain which could potentially inhibit the deteriorating effects of age and slow the progression of arthritis.
The primary goal of PRP is to resolve pain through healing, therefore, it could prove to have lasting results. Initial improvement may be seen within a few weeks and gradually increase as healing progresses. Research studies and clinical practice have demonstrated PRP injections to be very effective at relieving pain and returning patients to their normal lives.
Ultrasound and MRI imaging have both shown definitive tissue repair after PRP therapy thereby confirming the healing process. The need for surgery can also be greatly reduced by treating injured tissues before the damage progresses to an irreversible condition.
PRP can be used to accelerate autologous grafts used for site preparations, sinus lifts, osteointegration, ridge augmentations, etc. An enhanced bone regeneration can be expected when PRP is used with mixtures of autologous bone and bone substitutes and with recombinant human growth factors such as recombinant BMP. PRP has also been shown to increase the quantity and quality of the host bone in areas of localized alveolar defects when used for guided bone regeneration.
Early results are promising that PRP placed in the preparation site of a dental implant will promote and accelerate osteointegration. This may be beneficial in the maxilla, in areas of previous failures, in type IV bone, in osteoporotic women, etc.
A clinical trial that observed 20 patients undergoing cosmetic surgery) demonstrated bleeding capillaries were effectively sealed within three minutes after application of PRP and PPP.
An added advantage was that the use of electrocautery could be minimized, therefore decreasing the risk of damage to adjacent nerves.
Platelet rich plasma contains the bioactive proteins which act as the catalyst for accelerating the wound healing process. With the increased level of growth factors present in PRP, the tissue maturation phase is accelerated and the overall healing process is significantly improved in terms of post-operative pain, swelling, infection and establishment of tissue texture, colour and contour. PRP’s cohesive nature and its hemostatic properties also allow for minimal bleeding.
Growth factors found in PRP permit accelerated tissue regeneration. It can be used to treat corneal lesions and dystrophy, superficial punctuate keratitis, severe dry eye-related ocular surface disorders, ocular GvHD, recurrent erosion syndrome, neurotrophic keratopathy, keratopathy with loss of epithelial-stromal tissue resulting from chemical or physical traumas, sicca syndrome and/or Sjögren’s syndrome.
It also provides nutritional factors necessary to maintain cellular feasibility in the epithelial repair process while reducing the risk of contamination and infection.
Administration of a single intra-articular injection of autologous PRP resulted in significant improvements in dogs suffering from OA involving a single joint

The purpose of this trial was to determine the efficacy of a single IA injection of an autologous platelet concentrate for treatment of osteoarthritis in dogs. Dogs were randomly assigned to a treatment or control group. Dogs in the treatment group were then sedated, and a blood sample (55 mL) was obtained. PRP was then injected intra-articularly within 30 minutes. Control dogs were sedated and given an intra-articular injection of saline (0.9% NaCl) solution. Assessments were repeated 12 weeks after injection of platelets or saline solution.
For control dogs, lameness scores, pain scores, and PVF at week 12 were not significantly different from pre-treatment values. In contrast, for dogs that received platelet injections, lameness scores (55% decrease in median score), pain scores (53% decrease in median score), and PVF (12% increase in mean PVF) were significantly improved after 12 weeks, compared with pre-treatment values
It was concluded that in dogs suffering from OA involving a single joint, administration of a single intra-articular injection of autologous platelets resulted in significant improvements 12 weeks later, as determined by subjective (ie, owner-assigned scores for severity of pain and lameness) and objective (ie, PVF) measures.
A single intralesional treatment with PRP contributes to an earlier reduction of lameness and to an advanced organization of repair tissue

The purpose of this trial was to evaluate the effect of a single treatment of equine superficial digital flexor tendon (SDFT) disease with PRP on clinical and ultrasonographic parameters
Using a placebo-controlled clinical trial design, 20 horses with naturally occurring tendinopathies of forelimb SDFTs were randomly assigned to the PRP-treated group (n = 10) or control group (n = 10) after clinical and ultrasonographic examination. The SDFTs received an intralesional treatment with autologous PRP or were injected with saline, respectively (day 0).
Compared to day 0, lameness decreased significantly by week 8 after treatment with PRP and by week 12 in the control group. Ultra-sonographically there was no difference in the summarized cross-sectional area between the groups at any time point.
Ultrasound tissue characterization showed that echo types representing disorganized matrix decreased significantly throughout the observation period in the PRP-treated group.
Echo type II, representing discontinuous fascicles, not yet aligned into lines of stress was significantly higher 24 weeks after PRP treatment. 80% of the PRP treated horses reached their previous or a higher level of performance after 12 months compared to 50 % in the control group.
A single intralesional treatment with PRP up to 8 weeks after onset of clinical signs of tendinopathy contributes to an earlier reduction of lameness compared to saline treatment and to an advanced organization of repair tissue as the fibrillar matrix is getting organized into fascicles while remodelling continues.
Long-term, PRP treatment has the potential to increase the number of horses reaching their previous level of performance. Earlier treatment of tendinopathy with PRP should be considered to enhance these effects
PRP treated wounds showed more granulation formation and angiogenesis, faster epithelialization and collagen deposition than control wounds.

This study was conducted to identify the effectiveness of platelet-rich plasma (PRP) and efficacy of intralesional injection as a method of application to acute cutaneous wounds in dogs
Autologous PRP was separated from anticoagulant treated whole blood in three dogs. Cutaneous wounds were created and then treated by intralesional injection of PRP in the experimental group, while they were treated with saline in the control group on days 0, 2 and 4. The healing process was evaluated by gross examination throughout the experimental period and histologic examination on day 7, 14 and 21.
In PRP treated wounds, the mean diameter was smaller and the wound closure rate was higher than in the control. Compared with control wounds, total granulation indexes of PRP-treated wounds were increased on days 7 (p = 0.040) and 14 (p = 0.031).
The upper granulation index of PRP-treated wounds on Day 7 was significantly higher (p = 0.006) than that of the control while on day 14, the lower granulation index of the PRP-treated group was higher (p = 0.000)
The number of vessels was highest on day 7 in both the control and PRP-treated wounds and decreased gradually over the experimental period. More vessels were observed in the PRP-treated wounds than the control wounds on day 7 (p=0.0000). On day 7, PRP-treated wounds also displayed more collagen fibers than control wounds. The collagen fibers in all of the PRP-treated groups became denser and more abundant than those in the control group on day 14.
At day 21, most of the midportions and all of the upper portions of the dermis in PRP-treated wounds showed tightly packed collagen fibers running parallel to each other and the epidermis relative to control wounds.
