About PRP with Protein Concentrate
Standard PRP concentrates platelets. Your blood plasma also carries many other proteins, some of which help control inflammation and slow the enzymes that break down tissue inside an irritated joint. The protein concentrate step filters and concentrates these plasma proteins from the same blood draw.
The two preparations are injected together under ultrasound into the joint. The idea is to pair the platelets' repair signaling with proteins that may calm the joint environment. This approach is newer than standard PRP, and the research behind it is still growing, so we reserve it for specific situations.
Dr. Gruner offers this option mainly for people with arthritis who want to stay active. It is always paired with a strength and activity plan, since stronger muscles around a joint remain one of the most reliable ways to reduce arthritis pain over time.
What happens during treatment
- 1.
Dr. Gruner reviews your history, imaging, and an ultrasound exam to decide whether standard PRP or PRP with protein concentrate is the better fit.
- 2.
A larger blood draw than standard PRP is taken from your arm, because two separate preparations are made from it.
- 3.
The blood is processed in two ways: one to concentrate platelets and one to filter and concentrate plasma proteins.
- 4.
The skin is numbed, and both preparations are injected into the joint under live ultrasound guidance.
- 5.
You go home the same day with instructions for activity, medications, and follow-up.
Who may be a good candidate
- Adults with mild to moderate knee, hip, or shoulder arthritis who have not had enough relief from exercise and other conservative care.
- People who want to limit repeated steroid injections into a joint.
- Patients who are not ready for, or are not candidates for, joint replacement and want to stay active.
- People willing to follow a strengthening program after the injection.
Recovery
Expect the joint to feel sore, full, or stiff for a few days. Most people return to walking and light daily activity quickly and resume harder exercise gradually over the following weeks. Any improvement in pain and function typically builds slowly rather than overnight, and we reassess at follow-up.
Risks and limits
Risks are similar to standard PRP: post-injection soreness and swelling, bruising at the blood draw or injection site, and uncommon infection or bleeding. Anti-inflammatory medicines are usually paused around the procedure. Because this is a newer approach, the evidence is more limited than for standard PRP, and results vary. It is not appropriate for people with an active infection, certain blood disorders, or active cancer, and it does not replace joint replacement when arthritis is severe.
What to expect at your visit
- 1.
We listen first
Your visit opens with a real conversation: how the problem started, what you have already tried, and the activity you want back.
- 2.
Exam and in-office ultrasound
A hands-on exam, then ultrasound at the exam table, often while you move, so your physician can see the tendon, joint, or nerve involved.
- 3.
A clear diagnosis and plan
You leave knowing what is wrong and what your options are, from strength-based rehab to procedures, and why we recommend each one.
- 4.
Treatment and follow-through
Most procedures happen here in the office. We coordinate with your physical therapist and check progress against the goals you set.

Questions about PRP + Protein
- Is PRP with protein concentrate better than regular PRP?
- It is not better for everyone. It is designed for certain joint conditions, and the research is still developing. Dr. Gruner will explain which option makes more sense for your joint and goals.
- Where do the proteins come from?
- Both the platelets and the proteins come from your own blood, drawn the same day. Nothing from another person or animal is added. The proteins are filtered and concentrated from the liquid part of your blood, called plasma.
- Can PRP with protein concentrate delay knee replacement?
- Some people with arthritis use orthobiologic injections to manage pain and stay active while they are not ready for surgery. No injection can promise to delay or prevent joint replacement. If your arthritis is advanced, we will talk openly about when a surgical opinion makes sense.
