PRP Injections
Platelet-rich plasma therapy for joint and tendon healing.
Platelet-rich plasma (PRP) injections use a concentrated preparation of the patient's own blood platelets, which contain growth factors that may support tissue healing, injected directly into an affected joint or tendon. It is generally considered for certain cases of osteoarthritis and chronic tendon problems that have not responded fully to more standard treatment.
Types
Leukocyte-Rich PRP
A PRP preparation containing white blood cells alongside platelets.
Leukocyte-Poor PRP
A PRP preparation with white blood cells minimised, sometimes preferred for joint injections.
PRP for Joint Injection
Used for certain cases of osteoarthritis, particularly in the knee.
PRP for Tendon Injection
Used for chronic tendon conditions such as tennis elbow that have not responded to other treatment.
Common Causes
PRP injections are considered for specific conditions where standard treatment has provided incomplete relief, most commonly certain patterns of osteoarthritis and chronic tendon problems.
- Osteoarthritis not fully relieved by standard non-surgical treatment.
- Chronic tendon conditions, such as long-standing tennis or golfer's elbow.
- Patients wishing to explore additional non-surgical options before considering surgery.
- Certain soft tissue injuries where healing has stalled.
Signs and Symptoms
- Persistent joint or tendon pain despite standard treatment
- Symptoms that have plateaued with physiotherapy and medication alone
- Ongoing limitation in activity due to unresolved pain
- Interest in exploring options before considering surgery
Diagnosis
PRP is considered as part of an overall treatment plan once the underlying condition - typically osteoarthritis or a specific tendon problem - has already been diagnosed through clinical examination and appropriate imaging.
Treatment Approach
The procedure involves drawing a small blood sample, processing it to concentrate the platelets, and injecting the resulting preparation into the affected area, usually under clinical guidance. Evidence for PRP is still evolving and results vary between individuals, so it is generally discussed as one option among several rather than a guaranteed solution. Dr. K. G. Gopalakrishna discusses realistic expectations and whether PRP is a reasonable option for the specific condition being treated.
