What is PRP?
PRP (Platelet Rich Plasma) is a concentrate obtained from the patient's own blood, rich in growth factors naturally present in platelets. These biological elements have the ability to stimulate tissue repair and modulate inflammation.
Treatment begins with a simple blood test. After centrifugation, the enriched plasma is isolated and then injected directly into the joint affected by osteoarthritis (knee, hip, shoulder, ankle, or any other affected area). PRP is 100% autologous: it contains no medication, chemicals, or external agents.
In which case is it indicated?
PRP is particularly suitable for early to moderate forms of osteoarthritis, when cartilage is still present. It can be offered when conventional medical treatments (analgesics, cortisone injections, hyaluronic acid, etc.) become insufficient, ineffective, or contraindicated.
Dr. Coulin recommends it in particular in the following cases:
- Osteoarthritis of the knee, hip, or other weight-bearing joints
- Persistent chronic pain despite well-conducted medical treatment
- Local inflammation (synovitis) without severe joint damage
- Desire to delay surgery (prosthesis fitting)
- Maintenance or recovery of joint capital in young and active patients
PRP is also used as a complement to certain surgeries (meniscus, ligaments) to promote faster recovery.
What is the role of PRP in osteoarthritis?
Osteoarthritis is a degenerative disease that causes the progressive deterioration of joint cartilage. This wear and tear is accompanied by pain, joint stiffness, and loss of mobility.
PRP does not regenerate cartilage strictly speaking, but it acts effectively on several mechanisms:
- Reduction of local inflammation
- Improving the quality of synovial fluid (the natural lubricant of the joint)
- Long-lasting pain relief
- Better joint function
In some patients, stabilization of the osteoarthritic progression is observed. It is a natural, well-tolerated treatment that is part of a comprehensive care plan aimed at preserving joint mobility, avoiding or postponing the need for surgery.
How does the injection work with Dr. Coulin?
The injection is performed during a consultation at the office, in a rigorous but non-invasive medical setting. The steps are simple and quick:
- Blood collection
- Centrifugation – The blood is placed in a centrifuge to isolate the platelet-rich plasma.
- Preparation – The PRP is collected and placed in a sterile syringe, ready for injection.
- Intra-articular injection – precisely guided into the affected joint
The procedure is not very painful, does not require general anesthesia and does not affect the rest of the day.
What are the expected consequences and effects?
The after-effects of the injection are generally very straightforward. Moderate local discomfort may occur within 24 to 48 hours of the procedure, but a return to daily activities is generally immediate. However, it is advisable to avoid intense physical exertion for a few days.
The first effects usually appear between two and four weeks after the injection, with maximum benefits observed between one and three months. Patients notice a reduction in pain, improved joint mobility, and a reduction in the need for anti-inflammatory or painkiller medications.
The effectiveness of the treatment can last between six and twelve months. Depending on the evolution of symptoms, a renewal may be considered.
