Platelet-rich plasma, better known as PRP, started in operating rooms and professional locker rooms and has since become one of the most requested regenerative treatments in orthopedic and pain medicine. San Diego alone has dozens of clinics offering it, at price points and precision levels that vary more than most patients expect. This guide is for anyone weighing PRP for a knee, shoulder, tendon, or spine problem, or anyone whose physician has mentioned it as an alternative before surgery. Preparing PRP at a high dose and high concentration is critical to the treatment, and so is placing it with image guidance. At Advanced Pain & Regenerative Specialists we provide unparalleled care, preparing high-dose, high-concentration PRP and using image guidance for every injection.
What PRP Is and How It Works
PRP is a concentrate of platelets made from a sample of your own blood. Platelets are best known for clotting, but they also carry a payload of growth factors, the signaling proteins your body dispatches to injured tissue to organize repair and healing. A PRP injection takes the platelets from a blood draw, concentrates them to several times their normal level, and places them directly into the damaged joint, spine, tendon, or ligament.
From Blood Draw to Injection
Most patients find the whole process simpler than they expected. We draw blood the same way a lab does for routine testing, then spin it in a centrifuge. The spin separates the sample into layers, and we extract the platelet-rich layer while setting aside the red blood cells and most of the plasma. That concentrate goes into a syringe and is injected during the same visit. From draw to injection, the whole appointment usually runs about an hour, sometimes more depending on the procedure.
What Concentrated Platelets Do in Damaged Tissue
Once injected, the platelets release growth factors that recruit repair cells to the area, stimulate new blood vessel formation, and promote collagen production. The treatment is designed to amplify a healing response in tissues that struggle to mount one on their own. Tendons and cartilage have notoriously poor blood supply and few resident healing cells, which is a large part of why a strained Achilles or an arthritic knee heals slowly, or sometimes not at all. PRP delivers the biological signal for repair directly to the spot that needs it.
Conditions PRP Treats
PRP is used across a wide range of musculoskeletal problems, and the strength of the supporting research varies by condition. Here is where it stands for the problems we see most.
Knee Osteoarthritis
Knee arthritis carries the strongest research base of any PRP application. Multiple randomized trials and meta-analyses suggest PRP may outperform hyaluronic acid injections for pain and function in mild to moderate knee osteoarthritis, with improvements that often hold through six to twelve months. The key qualifier is staging, because PRP performs best when there is still cartilage to protect, which is why we grade the arthritis on imaging before recommending it. Corticosteroid injections may calm inflammation in the knee, but they also depress the function of the healing cells the joint relies on.
Tendon Injuries
Chronic tendon problems are the other area where the evidence is respectable. Tennis elbow has been studied extensively, and several trials suggest PRP may provide more durable relief than steroid injections once you look past the first few months. Patellar tendinopathy, Achilles tendinopathy, and partial rotator cuff tears are also common candidates. Degenerated tendon tissue with poor blood supply is precisely the environment PRP was designed for. Steroid injections decrease the inflammation but also leave the tendon weaker, while PRP works to heal the tendon, shorten recovery, and strengthen the healed tissue.
Shoulder, Hip, and Spine
PRP is also used for shoulder arthritis, hip arthritis, sacroiliac joint pain, and some spine conditions. The research in these areas is thinner than it is for the knee and elbow, and we say so plainly during consultation. The spine has small joints, called facet joints, that connect the vertebral bodies, and they commonly become arthritic and cause back pain. PRP injections into the facet joints and their supporting ligaments may help repair the source of back or neck pain. For some patients these injections are the better alternative, particularly when the other options are escalating medication or a surgery they want to avoid, but the conversation starts with an accurate picture of what the evidence supports.
What the Research Actually Shows
Patients deserve a straight summary of where the science stands. The evidence is strongest for mild to moderate knee osteoarthritis and chronic tendinopathy, where multiple randomized trials support meaningful improvement in pain and function. It is promising but mixed for hip arthritis, hamstring injuries, and acute muscle strains. One reason study results vary is that PRP itself varies. Preparation systems differ in platelet concentration and white blood cell content, and two clinics offering “PRP” may be injecting meaningfully different products. With current standards of practice, meaning high-dose, high-concentration PRP, the outcomes are more promising.
Just as important is what PRP will not do, and the list deserves the same clarity. It will not regrow cartilage in a bone-on-bone joint, reattach a full-thickness tendon tear, or substitute for surgery when the problem is structural. Clinics that promise otherwise are selling past the science, and that overselling has done more damage to the field’s reputation than any failed injection. When PRP is unlikely to help, the responsible move is to tell the patient before taking their money, and that is how we run our practice.
The Procedure, Visit by Visit
The Consultation
Every PRP treatment at our office starts with an evaluation by Dr. Boddu. That includes a physical exam, a review of your imaging, and a frank discussion of whether PRP fits your condition and your goals. We at Advanced Pain & Regenerative Specialists take a functional unit approach when we evaluate and treat our patients, because joint, tendon, and spine disorders are almost always multifactorial, and every structure involved needs to be treated for the best outcome. If PRP fits, you leave with preparation instructions, the most important of which is pausing anti-inflammatory medications such as ibuprofen and naproxen beforehand, since they can blunt the platelet response the treatment depends on. Exact pricing for your treatment plan is confirmed at this visit, before anything is scheduled.
The Day of the Injection
Plan on one to two hours, during which we draw your blood, centrifuge it while you wait, and prepare the injection site. Most patients describe the injection itself as pressure with brief discomfort, similar to a cortisone shot, and we also offer sedation for the procedure to maximize comfort. A local anesthetic can be used at the skin, though we use it sparingly near the target tissue because some anesthetics can interfere with platelet activity. After a short observation period, you go home the same day. You will want to arrange a driver if we are treating a weight-bearing joint or using sedation.
Ultrasound Guidance and Why It Matters
PRP only works if it reaches the target tissue, and studies of unguided joint and tendon injections show they miss the intended target far more often than most patients would guess. We perform PRP injections under image guidance so the concentrate is confirmed in the joint capsule or tendon sheath rather than the surrounding tissue. Any clinic quoting you a price for PRP should be able to tell you how they confirm placement. If the answer is experience and feel, the platelets may never reach the problem.
Recovery and Aftercare
Expect the treated area to be sore for two to five days. That soreness is part of the design, since PRP builds healing by increasing blood supply, stimulating healing cells, and attracting progenitor cells to the injury, and we ask patients to ride it out instead of reaching for anti-inflammatories. Acetaminophen is generally fine for comfort, and we provide a specific aftercare sheet for your treatment area. We will also prescribe pain medication to take care of post-procedure pain.
The first week calls for relative rest, meaning normal daily movement without loading the treated joint or tendon hard. From there, activity ramps up progressively, often alongside physical therapy, because the repairing tissue responds well to gradual load. Most patients notice early improvement somewhere between four and eight weeks, with gains that continue to build over three to six months. Depending on the condition, treatment may involve one injection or a series of two to three spaced several weeks apart, and we map that plan out during consultation, with the full course priced before you start.
What PRP Costs in San Diego
There is no standard price for PRP, and San Diego quotes reflect that. Most single-injection treatments in this market fall between $1,000 and $3,000, and more complex treatments cost more depending on the sites treated and the number of injections. The spread comes from real differences in what is being delivered. The preparation system and resulting platelet dose, the use of image guidance, the training of the person performing the injection, the body area being treated, and whether the quote covers one injection or a packaged series all move the number.
Insurance is the other half of the cost conversation, and the answer is simpler. Most insurers, including Medicare, classify PRP as investigational for orthopedic conditions and do not cover it. Patients pay out of pocket, though HSA and FSA funds can typically be applied. Be cautious with offers that undercut the market dramatically, because the corners being cut are usually platelet dose or image guidance, the two things that most influence whether the injection works. We confirm exact pricing during consultation, in writing, before you commit to anything.
PRP Compared With Cortisone, Stem Cells, and Surgery
PRP vs Cortisone
Cortisone calms inflammation quickly, and for an acute flare that speed can make it the right call, but its limits show up over time. Relief often fades within weeks to months, and a 2017 randomized trial published in JAMA found that repeated steroid injections into arthritic knees were associated with greater cartilage loss over two years compared with saline. Cortisone may help the pain, and over the long run it can make the underlying disorder worse. PRP moves in the opposite direction on both counts, working more slowly, typically over weeks, toward improving the tissue environment and healing rather than suppressing the symptom, with studies suggesting relief that lasts longer once it arrives.
PRP vs Stem Cell Therapy
PRP and stem cell therapy are both regenerative injections drawn from your own body, but they are different biologics with different jobs. PRP delivers growth factor signaling and suits mild to moderate arthritis and tendon problems. Stem cell treatments, typically drawn from your own bone marrow, bring repair cells themselves and are generally reserved for more advanced degeneration, at a meaningfully higher cost. We compare the two in depth in our article on PRP versus stem cell therapy.
When Surgery Is Still the Right Call
Some problems are structural, and biology alone will not fix them. Full-thickness tendon tears, advanced bone-on-bone arthritis, joints that mechanically lock or give way, and nerve compression with progressive weakness are surgical conversations, and we refer patients to trusted surgical colleagues when that is the better path. PRP earns its place before that point, and sometimes after it during recovery, but a practice that treats every problem as injectable is not evaluating, it is selling.
Who Is a Good Candidate
The patients who do best with PRP share a recognizable profile, and the consultation is where we check you against it. The strongest candidates bring most of the following traits into the exam room.
- Mild to moderate arthritis rather than end-stage disease
- A chronic tendon problem that has not resolved with rest and physical therapy
- A desire to delay or avoid surgery, backed by realistic expectations about what a biologic injection can deliver
- General health good enough to mount the healing response the treatment is built around
We counsel patients away from PRP when the joint is bone-on-bone, when there is an active infection, when certain blood or platelet disorders are present, or when expectations have outrun what the evidence supports. Some blood-thinning medications also require coordination with your prescribing physician before treatment.
PRP at Advanced Pain & Regenerative Specialists
PRP at our practice is physician-performed, image-guided, and preceded by an evaluation that takes candidacy seriously. Dr. Navneet Boddu is board-certified in both pain medicine and anesthesiology, a contributing author to the Atlas of Interventional Orthopedics Procedures and a regenerative medicine textbook, and a national and international lecturer on regenerative medicine. The physician who evaluates your case is the physician who performs your injection.
Our office is in Oceanside, serving Carlsbad, Vista, San Marcos, Encinitas, and the greater San Diego area. Details on the treatment itself are on our PRP injections page, and new patients can request an appointment online.
Frequently Asked Questions
How much does PRP cost in San Diego?
Most single-injection PRP treatments in San Diego run between $1,000 and $3,000, depending on the preparation system, image guidance, the body area treated, and whether the price covers a series. More complex treatments cost more depending on the sites treated and the number of injections. We confirm exact pricing at consultation before anything is scheduled.
Will insurance pay for PRP injections?
In most cases insurance does not pay for PRP injections. Insurers including Medicare classify it as investigational for orthopedic conditions, so treatment is typically out of pocket, though HSA and FSA funds can usually be applied.
How many PRP injections will I need?
The number of injections depends on the condition being treated. Many patients are treated with a single injection, while chronic tendon problems and arthritis are sometimes treated with a series of two to three injections spaced several weeks apart. The plan is set at consultation, priced as a whole course, and never sold visit by visit.
How long does a PRP injection last?
For knee arthritis, studies commonly report improvement lasting six to eighteen months, and some patients report longer. Duration varies with the condition, its severity, and how the tissue responds.
Is PRP worth the money?
For the right patient, the research supports it, particularly for mild to moderate knee arthritis and chronic tendinopathy. For the wrong patient, no injection is worth the money, which is why the evaluation matters more than the syringe.
What should I avoid after a PRP injection?
Anti-inflammatory medications such as ibuprofen and naproxen for several weeks, since they work against the inflammatory response PRP is designed to trigger, and hard loading of the treated area during the first week. We provide a full aftercare protocol for your specific treatment.
Is PRP the same as stem cell therapy?
PRP and stem cell therapy are related treatments, but they are not the same thing. PRP concentrates platelets and their growth factors from your blood to stimulate repair and healing, while stem cell therapy delivers repair cells themselves along with growth factors, usually from bone marrow. They suit different levels of tissue damage, and our comparison article walks through choosing between them.
