Key Takeaways
- Biologic injections, including platelet-rich plasma (PRP), use components drawn from the patient's own body to support natural tissue repair and reduce inflammation.
- PRP is created by drawing a small sample of blood, processing it in a centrifuge to concentrate the platelets, and injecting that concentrated plasma into the injured area.
- These injections are most commonly used for tendon injuries, ligament injuries, early osteoarthritis, and chronic joint pain affecting the shoulder, elbow, hand, and wrist.
- Most patients tolerate the procedure well, and noticeable improvements usually develop over several weeks as the tissue heals.
- Dr. Mark Yaffe is a board-certified orthopedic specialist offering biologic injection therapy in Buffalo Grove, Elk Grove Village, and Schaumburg, IL, and patients can request an appointment to find out whether biologic treatment is right for them.
Why Biologic Injections Have Become So Popular
Patients dealing with stubborn shoulder, elbow, hand, or wrist pain often find themselves caught between two extremes: trying to manage with rest and over-the-counter medication, or moving straight to surgery. Biologic injection therapy has emerged as a powerful middle option, one that taps the body's own healing biology to address the source of the problem rather than just masking the symptoms.
According to the American Academy of Orthopaedic Surgeons, orthobiologics are substances naturally found in the body that surgeons can use in higher concentrations to support the healing of broken bones, injured muscles, tendons, ligaments, and joints. For Dr. Yaffe's upper extremity patients, the most common biologic treatment is platelet-rich plasma, or PRP.
What Biologic Injections Are (PRP and Beyond)
The term 'biologic injection' covers a family of treatments that use natural materials, typically derived from the patient's own body, to encourage healing. The most established and widely used biologic in orthopedic care is PRP.
Platelet-rich plasma is a concentrated form of the patient's own platelets, suspended in a small amount of plasma. Platelets are the cells most people associate with clotting, but they also contain a rich supply of growth factors that direct tissue repair. By concentrating those platelets and delivering them directly to an injured tendon, ligament, or joint, PRP can amplify the body's natural healing response.
Other biologic products in orthopedics include:
- Bone graft materials that support healing of fractures and surgical reconstructions
- Bioinductive implants such as the Shoulder REGENETEN device, are used for select rotator cuff conditions
- Hyaluronic acid injections for certain joint conditions
- Other autologous tissue preparations that vary by clinical situation
Dr. Yaffe's biologic toolkit centers around PRP for non-surgical care and bioinductive options for select surgical cases, with treatment selection always tailored to the individual diagnosis.
How Biologic Injections Support Natural Healing
The science behind PRP and other biologic injections comes down to the growth factors and signaling molecules that platelets carry. When concentrated PRP is delivered into a damaged tendon, ligament, or joint, those growth factors trigger several healing processes:
- Recruiting repair cells to the area of injury
- Stimulating collagen production, the building block of tendon and ligament tissue
- Encouraging new blood vessel formation to nourish healing tissue
- Modulating inflammation so the body can move from chronic irritation to active repair
- Supporting the regeneration of damaged tissue rather than simple scar formation
Research has shown encouraging results for PRP in upper extremity tendon conditions. In a randomized controlled trial published in 2025, PRP injections produced superior functional outcomes at three and six months compared to corticosteroid and saline injections for the treatment of lateral epicondylitis (tennis elbow). That study supports PRP as a promising option for patients with chronic tendon problems who haven't responded to conservative care.
It's important to note that biologic injections are not instant pain relief. Cortisone tends to act faster but provides shorter-term relief, while PRP works more slowly and aims at longer-term healing of the underlying tissue.
Conditions Commonly Treated With Biologic Injections
Dr. Yaffe uses biologic injection therapy for a focused set of conditions where the evidence and clinical experience are strongest. These typically include:
- Tennis elbow (lateral epicondylitis) that hasn't improved with rest, therapy, or bracing
- Golfer's elbow (medial epicondylitis) in similarly persistent cases
- Rotator cuff tendinopathy or partial-thickness rotator cuff tears
- Articular cartilage injuries in the shoulder, elbow, or wrist
- Early osteoarthritis of the upper extremity joints
- Chronic tendon injuries in the hand, wrist, or elbow
- Ligament injuries that are healing slowly with conservative care
- Sports injuries affecting the shoulder and elbow
Patients dealing with these conditions often find biologic injections especially appealing because they avoid the risks of surgery and the side effects associated with repeated steroid use.
What the PRP Procedure Involves
A PRP injection is a same-day, in-office procedure that typically takes less than an hour from start to finish. The basic steps include:
1. Blood Draw
A small amount of blood is collected from the patient's arm, similar to a routine lab draw.
2. Centrifuge Processing
The blood sample is placed in a centrifuge, which spins it at high speed to separate out the components. The result is a concentrated layer of platelet-rich plasma.
3. Injection Preparation
The injection site is cleaned and often numbed with a local anesthetic to minimize discomfort.
4. Targeted Injection
Using anatomic landmarks and, in some cases, ultrasound guidance, Dr. Yaffe delivers the PRP directly into the area of damaged tissue.
5. Aftercare Instructions
Patients usually leave with simple instructions about activity modification, icing, and what to expect in the days that follow. Most return to normal daily activities quickly, with restrictions on heavy lifting or strenuous use of the area for a short period.
The procedure is well tolerated, and because PRP uses the patient's own blood, allergic reactions are essentially nonexistent.
Expected Results and Recovery Timeline
One of the most common questions patients ask is, 'How quickly will I feel better?' PRP doesn't work like a cortisone shot, which can dull pain within days. Instead, PRP works gradually as the body responds to the growth factors and begins repairing tissue. A typical timeline looks like:
| Time After Injection | What to Expect |
|---|---|
| First 1 to 3 days | Mild soreness or increased pain at the injection site |
| Week 1 | Soreness improves, return to most normal activities |
| Weeks 2 to 4 | Early signs of improvement begin to appear |
| Weeks 6 to 12 | Most noticeable functional and pain improvements |
| 3 to 6 months | Peak effect, with continued tissue remodeling |
Some patients only need a single injection, while others benefit from a short series of treatments spaced weeks apart. Dr. Yaffe tailors the plan based on the specific condition, the severity of the injury, and how the patient responds.
PRP Compared to Other Common Injections
To help patients understand where PRP fits, here's how it stacks up against other common injection options:
| Feature | PRP (Biologic) | Cortisone (Steroid) | Hyaluronic Acid |
|---|---|---|---|
| Source | Patient's own blood | Synthetic medication | Synthetic or animal-derived |
| Mechanism | Stimulates tissue healing | Reduces inflammation | Lubricates the joint |
| Speed of relief | Slower, several weeks | Faster, days | Variable |
| Duration of effect | Often months to longer-term | Weeks to a few months | Months |
| Repeated use | Generally safe with limits | Limited due to tissue effects | Periodic, depending on condition |
| Best for | Tendon, ligament, joint healing | Acute inflammation | Joint osteoarthritis |
For more on how PRP compares directly to cortisone for shoulder and elbow pain, Dr. Yaffe has discussed this in detail on his practice blog.
Who Is a Good Candidate for Biologic Injections?
PRP is not the right answer for every patient or every injury, but it can be an excellent option for certain situations. Ideal candidates often share several characteristics:
- Persistent tendon, ligament, or early joint pain that hasn't fully responded to rest, therapy, bracing, or medication
- A desire to avoid or delay surgery when possible
- An interest in regenerative treatment rather than long-term reliance on cortisone shots
- Overall good health with no medical conditions that interfere with platelet function
- Realistic expectations about a gradual, multi-week improvement curve
Patients with certain blood disorders, active infections, or other medical issues may not be candidates. Insurance coverage for PRP varies, so Dr. Yaffe's team helps patients understand both the clinical and financial picture before moving forward.
See If Biologic Injections Are Right for You
Biologic injection therapy gives many patients a path forward when conservative care has stalled and surgery feels premature. For the right conditions and the right patient, PRP can support real tissue healing with a simple, in-office procedure.

Frequently Asked Questions
What are biological treatments in orthopedics?
Biological treatments, also called orthobiologics, use natural substances such as a patient's own platelet-rich plasma or other concentrated tissue products to support the healing of injured tendons, ligaments, cartilage, and bone. Dr. Yaffe's practice focuses primarily on PRP for upper extremity conditions.
What is PRP therapy?
PRP, or platelet-rich plasma therapy, is a regenerative treatment in which a small amount of the patient's blood is processed to concentrate the platelets, then injected into an injured area. The growth factors in those platelets help recruit repair cells, stimulate collagen production, and support natural tissue healing.
What are regenerative medicine injections used for?
Regenerative medicine injections are most often used for chronic tendon injuries such as tennis elbow and rotator cuff tendinopathy, ligament injuries, early osteoarthritis, and stubborn joint pain that hasn't improved with standard conservative care. They aim to support real tissue repair rather than simply mask pain.
Is platelet rich plasma treatment painful?
Most patients tolerate the procedure well. The blood draw is similar to a routine lab test, and the injection site is usually numbed before treatment. Mild soreness for a few days after the injection is normal as the body begins its inflammatory healing response.
How many biologic injections will I need?
The number of injections depends on the condition being treated and how each patient responds. Some patients see significant improvement from a single PRP injection, while others benefit from a short series spaced weeks apart. Dr. Yaffe creates a personalized plan after evaluating each patient's diagnosis and goals.
