Platelet-Rich Fibrin for Sports Injuries

How PRF, PRP, and Chiropractic Care Support Recovery

Abstract

Sports injuries can damage tendons, ligaments, muscles, and joints, sometimes leading to pain that does not improve with rest alone. Platelet-rich plasma (PRP) and platelet-rich fibrin (PRF) are regenerative treatments made from a patient’s own blood. PRF is a newer approach that forms a natural fibrin matrix designed to hold platelets and healing signals near an injured area for a longer period. At Chiromed, regenerative therapies may be combined with integrative chiropractic care, rehabilitation, and medical oversight to address both tissue healing and the mechanical problems that may contribute to injury. This article explains how PRF works, how it differs from PRP, and how an integrated treatment plan may help support sports injury recovery.

Understanding PRP, PRF, and the Term “PFP”

A quick terminology clarification is important.

The most commonly accepted medical terms are platelet-rich plasma (PRP) and platelet-rich fibrin (PRF).

The term “platelet fibrin plasma,” sometimes shortened to “PFP,” may be used informally in some settings, but it is not the standard term used in most medical research.

Both PRP and PRF are made from a patient’s own blood. A small blood sample is collected and placed in a centrifuge, which spins the blood to separate its different parts.

The goal is to create a concentrated blood product containing platelets and other healing-related components that can be placed near an injured tendon, ligament, muscle, or joint.

Platelets are best known for helping the blood clot, but they also release growth factors and chemical signals that take part in tissue repair (Johns Hopkins Medicine, n.d.; Yale Medicine, n.d.).

What Is Platelet-Rich Plasma?

Platelet-rich plasma is usually prepared as a liquid. After the blood is processed, the platelet-rich portion is collected and injected into the injured area.

PRP has been studied for several orthopedic and sports-related conditions, including:

• Tennis elbow
• Golfer’s elbow
• Achilles tendinopathy
• Patellar tendon injuries
• Plantar fascia pain
• Selected rotator cuff injuries
• Mild-to-moderate ligament injuries
• Knee osteoarthritis

Research suggests that PRP may be more useful for certain conditions than others. Some of the strongest orthopedic evidence involves chronic tendon problems and knee osteoarthritis.

However, treatment results can vary because PRP preparation methods are not all the same. Platelet concentration, white blood cell content, injection technique, and the type of injury may all influence outcomes (Hospital for Special Surgery [HSS], 2024).

What Is Platelet-Rich Fibrin?

Platelet-rich fibrin is another blood-based treatment, but it is prepared differently from traditional PRP.

PRF is often processed at a lower centrifuge speed and typically without an added anticoagulant. This allows natural clotting to begin.

Instead of remaining completely liquid, PRF can form a thicker fibrin network or gel-like structure.

This fibrin network acts as a temporary biological scaffold.

It can hold:

• Platelets
• White blood cells
• Growth factors
• Signaling proteins
• Other blood-derived repair components

Because these components are held inside a fibrin matrix, researchers have proposed that PRF may release growth factors more gradually than some traditional PRP preparations (Grecu et al., 2019).

Why the Fibrin Scaffold Matters

Healing tissue needs more than one short burst of biological signals.

After an injury, the body moves through several stages of healing. These may include inflammation, new tissue formation, collagen rebuilding, and remodeling.

The fibrin structure created by PRF may help provide a temporary framework for these processes.

Think of the fibrin matrix like a small biological mesh.

Rather than allowing platelets to spread away from the treatment area quickly, the matrix may help keep them closer to damaged tissue.

This is one reason PRF has gained attention in regenerative medicine.

However, PRF research in sports medicine is still developing. PRP has a larger body of clinical research behind it. PRF remains promising, but more high-quality studies are needed to determine which injuries respond best and which preparation methods are most effective (Costa et al., 2025).

What Sports Injuries May Be Considered for PRF?

PRF may be considered for certain sports injuries after a complete examination.

Possible conditions include:

• Chronic tendon injuries
• Partial tendon tears
• Mild-to-moderate ligament injuries
• Slow-healing muscle injuries
• Joint irritation
• Early degenerative joint changes
• Certain overuse injuries

A regenerative injection is not automatically the correct treatment for every athlete.

The provider should first determine:

• Which structure is damaged
• How serious the injury is
• Whether the tissue is stable
• Whether surgery may be needed
• Whether the injury is acute or chronic
• What treatments have already been attempted
• What sport or activity the patient wants to return to

Severe injuries such as complete tendon ruptures, unstable joints, fractures, serious nerve injuries, or infections require appropriate medical evaluation before regenerative care is considered.

PRF Does Not Replace Rehabilitation

A common mistake is assuming that an injection alone will correct the entire injury.

PRF may support the injured tissue, but it does not automatically correct the reason the tissue became overloaded.

An athlete may also have problems such as:

• Limited joint movement
• Weak supporting muscles
• Poor posture
• Reduced balance
• Uneven movement
• Poor running mechanics
• Poor lifting technique
• Repetitive overuse
• Inadequate recovery between workouts

If these issues are not corrected, the injured tissue may continue to experience abnormal stress.

That is where integrative chiropractic care and rehabilitation can become an important part of the recovery process.

How Integrative Chiropractic Care Supports Sports Injury Recovery

At Chiromed, an integrated treatment approach can look beyond the painful area alone.

The goal is to identify both the injured tissue and the mechanical factors that may be contributing to the problem.

Integrative chiropractic care may include:

• Joint mobility assessment
• Chiropractic adjustments when appropriate
• Soft-tissue treatment
• Corrective exercises
• Mobility exercises
• Strengthening
• Balance training
• Postural correction
• Movement retraining
• Return-to-sport planning

For example, an athlete with knee pain may have hip weakness, poor ankle mobility, or poor landing mechanics.

A runner with Achilles tendon pain may have limited ankle motion or an uneven gait.

A shoulder injury may be related to poor shoulder blade control, weakness, or limited upper-back movement.

The goal is to identify these contributing factors so that injured tissue is not placed under the same harmful stress during recovery.

PRF and Chiropractic Care: A Biological and Mechanical Approach

Combining PRF with integrative chiropractic care creates two different treatment targets.

PRF focuses on biology.

It is designed to support the local healing environment around damaged tissue.

Chiropractic care and rehabilitation focus on mechanics.

They are used to improve joint motion, strength, flexibility, balance, coordination, and movement quality.

Together, these treatments may form part of a non-surgical sports injury recovery plan when they are clinically appropriate.

A patient’s plan may include:

1. A detailed examination
2. Review of imaging when needed
3. Identification of the injured structure
4. Regenerative treatment when appropriate
5. Temporary activity changes
6. Gentle mobility work
7. Gradual strengthening
8. Sport-specific rehabilitation
9. Functional testing before returning to activity

This type of progression can help reduce the risk of returning to sports too quickly.

Why Timing Matters After PRF or PRP

Immediately after a regenerative injection, the tissue needs time to respond.

Patients may experience temporary soreness, stiffness, or swelling.

Aggressive treatment is not usually the goal during the early stage.

Instead, rehabilitation may begin with controlled movement and gradually increase as the tissue becomes more comfortable and stronger.

The exact timeline depends on:

• The injured structure
• Severity of the injury
• The injection used
• Patient age
• Overall health
• Activity level
• Treatment goals

A patient recovering from a mild tendon injury may progress differently from someone with a chronic partial tear.

This is why recovery should be based on function rather than using the same schedule for every patient.

The Multidisciplinary Approach at Chiromed

Sports injuries can involve more than one system in the body.

That is why multidisciplinary care may be useful.

Chiromed’s integrative approach can bring together chiropractic care, rehabilitation, functional medicine principles, injury management, and medical oversight.

Dr. Alexander Jimenez, DC, APRN, FNP-BC, CCST, CFMP, IFMCP, ATN, combines chiropractic assessment with advanced clinical training in family practice and functional medicine.

His clinical approach commonly considers:

• Musculoskeletal function
• Joint mechanics
• Strength
• Mobility
• Lifestyle factors
• Nutrition
• Recovery habits
• Functional health
• Individual treatment goals

This allows sports injuries to be examined from more than one angle.

Rather than only asking, “Where does it hurt?” the treatment team may also ask why the injury developed and what can be changed to improve long-term function.

Medical Oversight and Collaborative Care

Dr. Maria Guadalupe Cardenas, MD, works alongside Dr. Jimenez as Medical Director and Collaborative Physician.

Dr. Cardenas is board-certified in internal medicine and has more than 40 years of clinical experience.

This type of medical collaboration may be valuable because regenerative treatment decisions can involve factors beyond the injured joint or tendon.

Medical evaluation may consider:

• Current medications
• Blood-thinning medications
• Blood disorders
• Infection risk
• Chronic disease
• Laboratory results
• Overall medical stability
• Whether an injection is appropriate

Working together allows the medical and chiropractic sides of care to support the same recovery goal.

Functional Medicine and Sports Recovery

Functional medicine principles may also be used to look at factors that can influence healing.

These may include:

• Protein intake
• Vitamin and mineral status
• Hydration
• Sleep
• Blood sugar control
• Stress
• Inflammation
• Recovery between workouts

These factors do not replace treatment for an injured tendon or ligament.

However, they may affect how well the body handles training and recovery.

An athlete who is not sleeping, eating enough protein, or allowing enough recovery time may have more difficulty rebuilding injured tissue.

Personal Injury and Rehabilitation Services

Although PRF may be discussed often in sports medicine, similar treatment principles may also be used in other musculoskeletal injuries.

Chiromed evaluates patients with injuries related to:

• Sports
• Exercise
• Workplace activities
• Motor vehicle accidents
• Repetitive movement
• Overuse
• Joint degeneration

The goal of treatment is to determine the source of pain and develop a plan based on the patient’s condition.

Rehabilitation then works to restore function rather than simply covering up symptoms.

Is PRF Better Than PRP?

There is no simple answer.

PRF has several interesting biological features because of its natural fibrin matrix and slower release of some growth factors.

PRP has been studied more widely in orthopedic medicine.

A provider may choose one preparation over another depending on the injury, treatment goals, available evidence, and clinical experience.

Patients should be cautious of claims that one treatment is always better than the other.

Regenerative medicine is not a one-size-fits-all process.

What PRF Cannot Do

PRF should not be described as a miracle treatment.

It cannot guarantee that damaged tissue will heal.

It also cannot:

• Repair every complete tendon rupture
• Replace severely damaged cartilage
• Correct an unstable fracture
• Remove serious nerve compression
• Treat an infection
• Eliminate the need for surgery in every case

Regenerative therapies work best when patients are selected carefully and realistic treatment goals are established.

Safety Considerations

PRF and PRP come from the patient’s own blood, which reduces the chance of an allergic reaction to the product itself.

However, injections still have possible risks.

These may include:

• Temporary pain
• Swelling
• Bruising
• Bleeding
• Infection
• Irritation of nearby tissue
• Lack of improvement

Patients should tell their healthcare provider about medications, supplements, previous illnesses, blood disorders, and other health conditions.

They should never stop aspirin, anti-inflammatory medicines, or prescription blood thinners without guidance from the appropriate medical provider.

Returning to Sports After Treatment

Returning to sports should be gradual.

Feeling less pain does not always mean the tissue is fully ready for competition.

Before returning, the athlete may need to demonstrate:

• Good range of motion
• Adequate strength
• Improved balance
• Controlled movement
• Limited or no pain with activity
• Ability to complete sport-specific drills

A good return-to-sport program also helps rebuild confidence.

The goal is not simply to return quickly.

The goal is to return safely and with enough strength and control to lower the chance of another injury.

A More Complete Way to Treat Sports Injuries

Modern sports injury care often works best when treatment addresses both the damaged tissue and the forces acting on that tissue.

PRF may help support the biological healing environment.

Integrative chiropractic care can help address movement problems.

Rehabilitation helps restore strength and function.

Medical oversight helps determine whether regenerative treatment is appropriate and safe.

Functional medicine principles may also support nutrition, sleep, recovery, and overall health.

Together, these services can create a more complete recovery plan.

Conclusion

Platelet-rich plasma and platelet-rich fibrin are blood-based regenerative treatments used in selected orthopedic and sports medicine cases.

PRF differs from traditional PRP because it forms a natural fibrin network that may hold platelets and healing signals near damaged tissue for a longer period.

Although PRF is promising, research is still developing, and it should not be presented as a guaranteed cure.

At Chiromed, regenerative care can be combined with integrative chiropractic treatment, medical oversight, rehabilitation, and functional medicine principles.

This multidisciplinary approach allows providers to address both sides of a sports injury: the biological needs of damaged tissue and the mechanical problems that may continue to place stress on it.

For athletes and active individuals, the goal is not only to reduce pain. It is to restore movement, rebuild strength, improve function, and create a safer path back to activity.
