Not every painful joint needs surgery—and not every patient needs the same injection. At Atlanta Bone & Joint Specialists, we start with the diagnosis and then help you understand whether cortisone, gel, PRP, an amniotic tissue or other orthobiologic treatment, cartilage restoration or another approach makes sense.
Patients often arrive knowing they want an injection but not knowing which type. These pages explain the major options, plus one emerging area we are actively reviewing as the evidence develops.
Gel injections, also called hyaluronic acid injections or viscosupplementation, are used primarily for symptoms related to knee osteoarthritis. They are different from cortisone and different from biologic treatments such as PRP.
Platelet-rich plasma (PRP) is prepared from a patient's own blood. It concentrates platelets and biologically active components and may be considered for selected arthritis, tendon and sports-medicine conditions.
“Stem cell therapy” is a broad term used for several different tissue-based treatments. The science and terminology can be confusing, so this page focuses on what these treatments actually are, what is still being studied and what patients should understand before paying for one.
A focal cartilage defect is not the same thing as generalized osteoarthritis. Selected patients—often younger or more active—may have joint-preservation options designed specifically around a localized area of cartilage damage.
Amniotic and other birth-tissue-derived products are sometimes marketed as regenerative injections for arthritis and soft-tissue problems. Products in this category can differ substantially in composition, processing, evidence and regulatory status, so patients should understand exactly what product is being proposed and what data support its use.
BPC-157 and other peptides are receiving attention for possible musculoskeletal healing. Human orthopedic data remain limited, and we do not currently offer peptide therapy. We are following the evidence as higher-quality research becomes available.
Knee, shoulder and hip pain can come from very different problems. Treating every painful joint with the same injection does not make sense. The right treatment depends on what is actually damaged, how advanced the problem is, your goals and what has already been tried.
Start With an Orthopedic EvaluationHistory, examination and appropriate imaging help distinguish arthritis, tendon disease, cartilage injury and other causes.
Mild or focal disease may have very different options from advanced structural arthritis.
Sometimes that is therapy or medication. Sometimes it is an injection. Sometimes another treatment makes more sense.
The goal is not to keep repeating procedures indefinitely; it is to move treatment forward when symptoms or disease progression warrant it.
These treatments are not interchangeable. This quick comparison is a starting point—not a substitute for examining the joint and making a diagnosis.
| Treatment | What it is | Common orthopedic use | Key point |
|---|---|---|---|
| Cortisone | Anti-inflammatory medication | Selected painful or inflamed joints, bursae and soft-tissue conditions | Often useful when inflammation is an important part of the problem |
| Gel / Hyaluronic Acid | Viscosupplement injected into the joint | Primarily knee osteoarthritis | Not a steroid and not a stem-cell treatment |
| PRP | Concentrated platelets prepared from the patient's blood | Selected arthritis, tendon and sports-medicine conditions | Evidence and expected benefit vary by diagnosis |
| Orthobiologics | Broad category that may include tissue- or marrow-based preparations | Selected orthopedic conditions | Terminology and evidence vary; avoid promises of guaranteed cartilage regrowth |
| Amniotic Tissue–Derived Products | Products derived from donated birth tissues; composition varies by product | Sometimes marketed for arthritis and soft-tissue conditions | Evidence and regulatory status vary; no amniotic product is FDA-approved to treat an orthopedic condition |
Insurance coverage, out-of-pocket cost, indications and availability vary by treatment, diagnosis, payer and individual clinical circumstances.
The term is used loosely online. We prefer to be specific about what is being injected, what problem it is intended to treat and what the evidence can reasonably support.
Age, diagnosis, severity, activity level, prior treatment and patient goals all matter when deciding whether an injection is worth considering.
A treatment may help pain or function without recreating normal cartilage. Patients deserve to understand that distinction before choosing a procedure.
Some patients can remain active with nonsurgical treatment. Others may eventually be better served by cartilage restoration or joint replacement when structural disease is advanced.
New treatments deserve interest—but they also deserve the same standard of evidence we apply to everything else in medicine.
BPC-157 and other peptides are receiving significant attention for possible effects on tendon, ligament, muscle and other tissue healing. There are interesting preclinical data, but human orthopedic evidence remains very limited.
As physicians, we have to evaluate more than whether a treatment sounds biologically promising. We need reliable human data on safety, dosing, product quality, effectiveness and which patients—if any—actually benefit.
Many injections can be performed accurately using anatomic landmarks. For selected deep, small or difficult targets, point-of-care ultrasound allows the physician to visualize the needle and intended structure in real time.
Learn About Ultrasound-Guided InjectionsStraight answers to the questions patients commonly ask before choosing between gel, PRP, cortisone, amniotic tissue and other orthobiologic treatments.
There is no single best injection for every knee. The choice depends on the degree of arthritis, symptoms, prior treatment, age, activity level, medical history and goals. Cortisone, gel injections and PRP are different treatments with different strengths and limitations.
Not for every patient. Gel injections are used primarily for knee osteoarthritis, while PRP may be discussed for selected arthritis and tendon conditions. The more useful question is which treatment fits the specific diagnosis and stage of disease.
No. PRP is prepared from a patient's blood and concentrates platelets and associated biologically active components. Tissue- or marrow-based orthobiologic treatments are different procedures.
Patients should be cautious with claims that an injection can reliably recreate normal cartilage or reverse advanced arthritis. Some biologic treatments are studied for symptom and functional improvement, but that is different from guaranteeing restoration of a normal joint.
Some patients can manage symptoms for extended periods without surgery, especially when arthritis is not advanced. Injections do not reliably reverse severe structural arthritis, so joint replacement may eventually become the more appropriate treatment for some patients.
These are products derived from donated birth tissues and marketed in several different forms. Their composition, processing, biologic activity and regulatory status can vary substantially. No amniotic product is FDA-approved to treat an orthopedic condition, so patients should understand the specific product and evidence before considering treatment.
Not at this time. BPC-157 has interesting preclinical data, but human orthopedic evidence remains limited and it is not FDA-approved. We believe additional high-quality human data on safety, dosing, product quality and effectiveness are needed before offering it in our office.
Not always. A history, physical examination and X-rays often provide substantial information. MRI or ultrasound may be added when the additional imaging is likely to change the diagnosis or treatment plan.
Atlanta Bone & Joint Specialists serves patients through offices in Decatur, Snellville and Loganville, Georgia. The availability of a specific injection or biologic procedure may vary by physician, diagnosis and location.
You should not have to diagnose yourself or choose a procedure from a menu before seeing an orthopedic physician. Start with the problem, understand the options and then decide what makes sense.
