What Is PRP Treatment for Knee Pain?

PRP treatment for knee pain works by drawing a small sample of your own blood, processing it in a centrifuge to separate and concentrate the platelets, then injecting that concentrated solution directly into the knee joint. Those platelets carry growth factors that help calm inflammation and encourage the joint’s own repair process. No foreign substance enters the body. No surgical procedure is involved. What sets PRP apart from most other injections is that the active ingredient comes from the patient themselves. It’s most often considered for people dealing with early to moderate knee arthritis, gradual cartilage wear or joint pain that hasn’t responded well enough to standard treatment.

According to Dr. Saurabh Talekar, orthopedic surgeon in Kandivali, “PRP isn’t a cure. It’s a way of using what the body already has and concentrating it where healing is needed. For the right patient, it can reduce pain meaningfully and buy considerable time before any surgical decision needs to be made. Patient selection is everything with PRP.”

The procedure itself is simple enough. What the body does with it afterward is where it gets interesting.

Blood Draw and Processing: A small amount of blood is drawn from the patient’s arm, similar to any routine blood test. That sample goes into a centrifuge which spins it at high speed, pulling the platelets away from the red and white blood cells. What remains is a concentrated platelet solution ready for injection.

Role of Platelets: Platelets do more than stop bleeding. They release growth factors that trigger tissue repair, help regulate inflammation and support cartilage cell regeneration. In a knee that’s been worn down over time, those signals aren’t strong enough on their own. PRP delivers them in a concentrated dose, right where the joint needs them most.

The Injection: The concentrate is injected into the knee, usually with ultrasound guidance to ensure accuracy. The whole thing takes under thirty minutes. Outpatient setting, no anaesthesia, no overnight stay.

What It Targets: PRP knee treatment is most commonly used for osteoarthritis, cartilage degeneration and certain tendon or ligament injuries around the joint. Rather than simply reducing pain signals, it targets the underlying tissue environment. That’s a meaningful clinical difference.

PRP sits between conservative care and surgery. Here’s how it lines up.

Steroid Injections: These work quickly and can bring significant short-term relief. Repeated use over time, however, can weaken cartilage and soft tissue. PRP doesn’t carry that risk because it’s autologous, meaning it comes from the patient’s own body.

Hyaluronic Acid: Often called a lubricant injection, it works by improving the quality of joint fluid. PRP goes a step further by actively promoting tissue repair rather than just reducing friction. Some evidence suggests PRP may outperform hyaluronic acid for pain relief in knee arthritis.

Physiotherapy and Medications: These remain the starting point for knee pain management and PRP doesn’t change that. It comes into consideration once standard conservative care has run its course and the patient still isn’t getting the relief they need, but surgery isn’t yet the right call.

Surgery: For patients who want to avoid or delay knee replacement, PRP treatment can create room to do that. Not everyone needs surgery and PRP gives both patient and clinician more time before that decision has to be made.

Understanding how PRP fits into the bigger picture of knee care starts with getting the right diagnosis before treatment. See how tendinitis and tendinosis in the elbow follow the same principle.

Dr. Saurabh Talekar holds an MRCS from the Royal College of Surgeons of Edinburgh and a fellowship in adult hip and knee replacement, with years of clinical experience assessing and managing knee conditions across the full spectrum of severity. His approach to PRP is grounded in proper patient selection, which is what determines whether PRP actually delivers results.

PRP works well for some patients and does very little for others. The difference usually comes down to how carefully the candidate was assessed beforehand. Dr.Talekar’s evaluation process identifies who genuinely stands to benefit before any injection is planned, so the procedure is clinically justified rather than reflexive. For suitable candidates, the aim is real pain reduction and maintained joint function, without escalating to surgery before it’s truly necessary. Call +91 9136363669 to book your consultation.
