PRP Growth Factor Therapy for Tissue Repair
At Full Circle Orthopedics and Sports Medicine, PRP Growth Factor Therapy works by concentrating your own platelets and delivering their growth factors directly into damaged tissue. This makes PRP Growth Factor Therapy one of the most versatile tools we offer, supporting repair in tendons, ligaments, muscle, and mildly irritated joints without surgery.
Our founder Courtney Kelm has spent more than twenty-five years working in health care and has helped thousands of patients find meaningful pain relief without surgery. She combines clinical experience, attention to detail, and advanced regenerative training to offer PRP injections that are safer, more precise, and more effective than what many practices provide.
We have treated patients who want to stay active, avoid surgery, recover from sports injuries, and manage chronic orthopedic conditions in a natural way. Every PRP treatment is performed with ultrasound guidance for accuracy and safety, and we use a high quality centrifuge system that produces a consistent, concentrated platelet product.
This page focuses on orthopedic PRP injections only. Full Circle does not perform cosmetic PRP for hair, skin, or aesthetic procedures.
How PRP Growth Factor Therapy Works
Your blood contains red blood cells, white blood cells, plasma, and platelets. Platelets carry growth factors that signal the body to repair tissue, build new cells, and reduce inflammation at the site of injury. PRP injections isolate and concentrate these growth factors, then deliver them precisely where repair is needed.
Typical blood contains about six percent platelets. When PRP is prepared through a high quality centrifuge, the platelet concentration can reach five to ten times that amount. This higher concentration of growth factors gives PRP injections their therapeutic effect, and their clinical use for musculoskeletal conditions continues to be studied on PubMed’s research database.
PRP injections are used for:
- Knee pain including strains, sprains, and early osteoarthritis
- Tendon injuries such as tennis elbow or rotator cuff irritation
- Chronic overuse injuries
- Muscle injuries
- Ligament sprains
- Joint irritation or degeneration
- Persistent pain that has not improved with physical therapy or steroid injections
PRP injections are appropriate for many orthopedic concerns, but every patient is evaluated first to determine if it is the right choice.
What Happens During PRP Injections
Your appointment includes several steps that make PRP injections safe and effective.
- A small sample of blood is taken from your arm, similar to a routine lab draw.
- The blood is placed in our centrifuge machine where platelets are separated and concentrated.
- The treatment area is cleaned and prepared.
- Local anesthetic is used to minimize discomfort.
- Courtney administers the PRP injection into the affected area using ultrasound guidance for accuracy.
- You rest in the office for several minutes before leaving.
Most visits take less than an hour. PRP injections are considered a minimally invasive procedure and do not require sedation, stitches, or time off from daily life beyond simple rest.
What to Expect After PRP Injections
It is common to feel sore or achy for two to three days after treatment. Some patients notice soreness for up to seven to fourteen days as the healing process becomes active. This is normal and expected.
General guidance includes:
- Avoid anti-inflammatory medications for one week
- Use Tylenol if needed
- Avoid ice during the early healing phase
- Rest the area for several days
- Resume light activity after ten to fourteen days
- Resume normal training or sport after about one month, depending on the area treated
Most patients feel improvement between six and eight weeks. Some progress sooner, while others need more time depending on the severity of the injury or condition.
Research supports that a series of two or three PRP injections can be more effective than one. Courtney makes individualized recommendations for each patient.
PRP Injections: Risks and Considerations
PRP injections are considered a safe procedure because they use your own platelets. Complications are rare but may include:
- Increased pain after injection
- Infection
- Irritation of nerves or soft tissue
- Scar tissue or calcification at the injection site
Courtney discusses all risks, benefits, and alternatives during your consultation.
Choosing Between PRP and A2M
PRP injections and A2M work through different mechanisms. PRP delivers a broad concentration of growth factors that support repair across tendons, ligaments, and muscle. A2M, by contrast, is concentrated specifically to neutralize the destructive enzymes that break down cartilage, making it a more targeted option for joint degeneration and arthritis.
Many patients benefit most from PRP injections for tendon and soft tissue injuries, while A2M is often the better fit when cartilage protection is the primary goal. Both are prepared from your own blood using our high-quality centrifuge system, and Courtney will help determine which approach, or combination, fits your specific injury.

FAQ: PRP Injections | Phoenix
Platelet Rich Plasma (PRP) injections use concentrated platelets from your own blood to support healing in joints, tendons, and ligaments. PRP delivers growth factors directly to the affected area to help decrease inflammation, encourage tissue repair, and reduce orthopedic pain without surgery. It works with your body’s natural healing process and is often used for injuries such as tendon irritation, sprains, joint pain, or partial tears.
PRP therapy can help tendon injuries such as tennis elbow, chronic muscle injuries, early osteoarthritis, knee pain, partial tears, and overuse injuries. Many patients choose PRP when they want to manage pain naturally and avoid steroid injections.
Yes. PRP injections are considered generally safe because they use your own plasma and platelets. There are minimal risks of allergic reaction. The main potential risks come from the injection process itself, such as temporary soreness or irritation at the injection site.
Most patients feel sore for two to three days. Many return to light activities or physical therapy within two weeks and can return to normal activities within a month. Full improvement usually appears between six and twelve weeks as tissue heals.
A small blood sample is collected and placed in a centrifuge machine that separates concentrated platelets from red blood cells and plasma. These concentrated platelets contain growth factors that support tissue repair.
Many patients do well with one treatment. For tendon injuries or chronic issues, a series of two treatments spaced four weeks apart can offer stronger results. Each plan is individualized.
Most patients describe mild pressure or discomfort. A local anesthetic is used before the injection, and the area may feel sore for a few days as the healing process begins.
PRP can help manage pain and support joint health in early stages of osteoarthritis. For more advanced arthritis, A2M may be recommended as it targets the chemicals that worsen joint degeneration.
Steroid injections reduce inflammation but do not promote healing and can weaken tissue over time. PRP injections support tissue repair with your own growth factors and have minimal long-term risks.
