PRP Injection Therapy for Knee Pain: A Non-Surgical Option for Selected Patients- By Dr. Balaraju Naidu, Robotic Orthopedic Surgeon, ONUS Robotic Hospitals
Introduction
Knee pain is one of the most common orthopedic complaints, affecting people of all ages but especially those with osteoarthritis. As knee arthritis progresses, patients may experience pain, stiffness, swelling, and difficulty performing routine activities such as walking, climbing stairs, or standing for long periods.
Many individuals worry that knee pain automatically means surgery. However, depending on the stage of arthritis and the patient’s overall condition, several non-surgical treatment options may be considered before surgery becomes necessary.
One such treatment is PRP (Platelet-Rich Plasma) Injection Therapy, which has gained attention as a regenerative treatment option for selected patients with knee osteoarthritis.
According to Dr. Balaraju Naidu, Robotic Orthopedic Surgeon at ONUS Robotic Hospitals, proper evaluation is essential to determine whether PRP is appropriate for a patient’s specific condition.
Understanding Knee Osteoarthritis
Osteoarthritis is a degenerative joint condition that occurs when the protective cartilage covering the ends of bones gradually wears away.
As cartilage deteriorates:
- Joint surfaces become rough
- Friction increases
- Inflammation develops
- Pain and stiffness worsen
- Movement becomes restricted
Over time, everyday activities can become increasingly difficult.
Common Symptoms of Knee Osteoarthritis
Patients with knee arthritis may experience:
Knee Pain
Pain may occur during walking, standing, climbing stairs, or after prolonged activity.
Morning Stiffness
The knee may feel stiff after waking up or after sitting for long periods.
Swelling
Inflammation within the joint can cause visible swelling.
Reduced Mobility
Patients often notice difficulty bending or straightening the knee.
Grinding Sensation
Some people experience clicking, cracking, or grinding sounds during movement.
Difficulty Walking
As arthritis progresses, walking longer distances becomes more challenging.
What Is PRP (Platelet-Rich Plasma) Therapy?
PRP stands for Platelet-Rich Plasma, a concentrated preparation derived from the patient’s own blood.
Platelets are natural blood components that contain growth factors and proteins involved in tissue repair and healing processes.
PRP therapy involves:
- Drawing a small amount of the patient’s blood.
- Processing it using specialized equipment.
- Separating platelet-rich plasma from other blood components.
- Injecting the concentrated PRP into the affected knee joint.
The procedure is performed under medical supervision after proper orthopedic evaluation.
How PRP May Help Knee Pain
PRP therapy is designed to support the body’s natural healing response.
In selected patients, PRP may help:
Reduce Pain
Some patients report reduced knee discomfort after treatment.
Improve Joint Function
Better movement and improved daily activity performance may be possible.
Enhance Mobility
Reduced symptoms can support more comfortable walking and physical activity.
Improve Quality of Life
Less pain often allows patients to remain active and independent.
However, results vary between individuals.
Who May Benefit From PRP Therapy?
PRP is not suitable for every patient with knee arthritis.
It may be considered for selected individuals with:
- Early-stage osteoarthritis
- Mild to moderate cartilage wear
- Persistent knee pain
- Functional limitations despite conservative treatment
- Desire to explore non-surgical treatment options
The decision should always be based on clinical evaluation and imaging findings.
Is PRP Suitable for Advanced Arthritis?
This is one of the most important questions patients ask.
While PRP may help selected patients with early-stage arthritis, advanced osteoarthritis often requires different treatment approaches.
In severe arthritis:
- Cartilage loss may be extensive
- Joint deformity may be present
- Functional limitations may be significant
In such cases, PRP may not provide the desired results, and other treatment options—including knee replacement surgery—may need to be considered.
Why Proper Evaluation Is Essential
No two patients with knee pain are exactly alike.
A thorough orthopedic assessment helps determine:
- The stage of arthritis
- Severity of symptoms
- Joint alignment
- Functional limitations
- Previous treatments
- Overall health status
Proper evaluation helps ensure the right treatment is selected for the right patient.
Investigations Before PRP Treatment
Depending on the patient’s condition, evaluation may include:
Clinical Examination
Assessment of pain, mobility, stability, and function.
X-Rays
Help determine the extent of joint degeneration.
Additional Imaging
In selected cases, MRI or other investigations may be required.
These assessments help determine whether PRP is likely to be beneficial.
