If you have been living with chronic joint pain and wondering whether there is something beyond rest, cortisone shots, and surgery, you are not alone. More patients seeking PRP injections in Sacramento are asking this exact question — and for good reason. Platelet rich plasma therapy has moved from experimental to mainstream over the last decade, and the results for the right patients can be significant.
At Sacramento Orthopedic Sports & Shoulder, Dr. Greg Takenishi and his team work specifically with athletes and individuals dealing with sports-related injuries and shoulder conditions. With over 15 years of experience evaluating and treating these cases, the practice has a front-row view of when PRP works, when it does not, and how to match the right treatment to the right patient.
But is it actually worth it? Here is an honest breakdown of what the science says, who it helps most, and what you can realistically expect.
What Is Platelet Rich Plasma Therapy?
Platelet rich plasma therapy is a regenerative treatment that uses your own blood to accelerate healing. A small sample of blood is drawn from your arm, then spun in a centrifuge to concentrate the platelets — the cells that trigger tissue repair and reduce inflammation.
That concentrated plasma is then injected directly into the damaged area: a knee, shoulder, hip, or tendon. The goal is not to mask pain. It is to stimulate the body’s own healing response at the site of injury.
Because the treatment uses your own blood, the risk of allergic reaction is extremely low. There are no synthetic drugs involved.
How PRP Injections Work
Platelets contain growth factors — proteins that signal the body to send healing cells to an injured area. In healthy tissue, this process happens naturally. In chronic injuries, the healing signal often stalls.
PRP jumpstarts that process. By flooding the damaged tissue with a concentration of growth factors that is 5 to 10 times higher than what naturally circulates in your blood, the injection can restart tissue repair that the body had essentially given up on.
The process itself is straightforward:
- A blood draw takes about five minutes
- The centrifuge spin takes roughly 15 minutes
- The injection is guided by ultrasound imaging for precision
- Most patients go home the same day
There is typically a short recovery window — light activity for a few days — before most people return to normal movement.
PRP for Knee Pain: What the Research Shows
PRP for knee pain, particularly osteoarthritis of the knee, has some of the strongest evidence behind it among all PRP applications. Multiple randomized controlled trials have compared PRP to hyaluronic acid injections and corticosteroids, and PRP consistently shows better pain reduction and functional improvement at the six-month and 12-month marks.
A 2023 meta-analysis published in the American Journal of Sports Medicine found that PRP significantly outperformed placebo for knee osteoarthritis — with benefits lasting well beyond what cortisone provides.
PRP also shows strong results for:
- Patellar tendinopathy (jumper’s knee)
- IT band syndrome
- Meniscus irritation (in certain cases, not full tears)
- Post-surgical knee recovery
For patients with mild to moderate knee osteoarthritis who are not yet candidates for replacement, PRP often provides meaningful relief that buys real time — sometimes years — before more invasive intervention becomes necessary.
PRP for Shoulder Pain: A Promising Option
PRP for shoulder pain is another area where the evidence is growing. Rotator cuff injuries are among the most common reasons patients seek orthopedic care, and they sit in a frustrating middle ground — too significant to heal on their own, but not always severe enough to justify surgery.
PRP has shown particular promise for:
- Partial rotator cuff tears (not full thickness)
- Shoulder tendinopathy
- Biceps tendon irritation
- Chronic shoulder bursitis
- AC joint pain
For full rotator cuff tears, PRP alone is typically not enough. But used alongside surgical repair, it can improve healing rates and speed recovery. Some studies suggest it also reduces re-tear risk when used as a surgical adjunct.
If you have been told your shoulder “just needs rest” but have seen little progress, a PRP evaluation is worth having.
PRP vs Surgery: Which Is Right for You?
The PRP vs surgery conversation depends heavily on the specific injury, its severity, your age, and your activity goals. PRP is not a replacement for surgery in every case — but it does provide a real alternative in many.
Here is a general framework for thinking about it:
| Condition | PRP a Good Option? | Surgery More Appropriate? |
| Mild to moderate knee OA | Yes | Only if PRP fails |
| Partial rotator cuff tear | Often yes | If >50% thickness or complete |
| Achilles tendinopathy | Yes | Rarely, and only after conservative care |
| ACL tear | Adjunct only | Yes, for active patients |
| Full meniscus tear | No | Typically yes |
| Chronic lateral epicondylitis (tennis elbow) | Yes | Rarely needed |
The biggest advantage of PRP over surgery is recovery time. A PRP injection has a few days of soreness. Surgery has weeks to months of structured rehab, time off work, and real risk of complications.
For patients who are not surgical candidates due to age or general health, PRP often represents one of the few remaining regenerative options available.
Who Is a Good Candidate for PRP?
PRP works best for patients who:
- Have a specific, diagnosable source of joint pain (confirmed by MRI or ultrasound)
- Have not responded adequately to physical therapy or cortisone alone
- Are not yet at the stage where joint replacement is the only reasonable option
- Do not have active infection, blood disorders, or platelet dysfunction
- Are not currently on blood thinners (some can be paused with physician guidance)
PRP is not a cure-all. Managing expectations matters. Most patients see gradual improvement over six to twelve weeks as healing progresses, not overnight relief. Some require two or three injection cycles for optimal results.
What to Expect from PRP Injections in Sacramento
At Sacramento Orthopedic Sports & Shoulder, the process starts well before the injection. Dr. Takenishi conducts a thorough orthopedic assessment to identify the specific source of your pain. Imaging is reviewed or ordered to confirm the diagnosis and determine whether PRP is the right fit for your case — not every patient is a good candidate, and that evaluation matters.
Because the practice focuses exclusively on sports-related injuries and shoulder conditions, Dr. Takenishi brings a level of specialization that general orthopedic practices often cannot match. Athletes and active patients benefit from a treatment approach that accounts for performance goals, not just pain management.
The injection itself is ultrasound-guided, which improves accuracy and outcomes compared to landmark-based injections. After the procedure, a structured activity plan helps the body respond to the treatment correctly.
Most patients tolerate PRP very well. A day or two of increased soreness at the injection site is common as the inflammatory healing response begins — that is actually a sign the treatment is working.
Follow-up typically happens at the four-to-six week mark to assess progress and decide whether additional injections are warranted.
Frequently Asked Questions
How many PRP injections will I need? Most conditions respond to one to three injections spaced four to six weeks apart. Knee osteoarthritis often responds well to a single injection series. Tendon injuries sometimes require repeat treatment.
Does insurance cover PRP? Most commercial insurance plans do not cover PRP, as it is still classified as investigational for many diagnoses. However, some plans offer partial coverage. Our team can help you understand your options.
How long does PRP relief last? For knee osteoarthritis, studies show meaningful relief lasting 12 to 18 months or longer. Results vary by individual and condition severity.
Is PRP painful? The injection itself involves mild discomfort, similar to any joint injection. Post-procedure soreness typically resolves within 48 to 72 hours.
Can I combine PRP with other treatments? Yes. PRP is often most effective when combined with physical therapy, activity modification, and anti-inflammatory lifestyle changes.
The Bottom Line
Platelet rich plasma therapy is not a miracle cure, but for the right patients and the right conditions, it is one of the most effective non-surgical tools in orthopedic medicine today. If you have joint pain that has not responded to conservative care, and you want to explore your options before committing to surgery, PRP is a conversation worth having.
Sacramento Orthopedic Sports & Shoulder specializes in exactly these cases. Dr. Greg Takenishi has spent over 15 years helping athletes and active patients get back to doing what they love — with as little intervention as necessary.
