PRP Tendon/Ligament Injection

Platelet-rich plasma (PRP) injections for tendons and ligaments are primarily used to treat degenerative and injury-related conditions in these connective tissues. Based on available evidence, the main clinical applications include:

Primary Conditions Treated:

• Lateral epicondylosis (tennis elbow)
• Chronic tendon injuries
• Acute ligament injuries
• Pectoralis major tendon injuries requiring repair
• Knee osteoarthritis (as an adjunct treatment affecting periarticular structures)

Treatment Goals:
The therapy aims to promote tissue healing and regeneration by delivering concentrated platelets and growth factors directly to injured areas. PRP is intended to accelerate the body's natural healing processes in tendons and ligaments, which typically have poor blood supply and heal slowly.

Clinical Evidence:
The evidence base shows growing research interest, with a bibliometric study identifying significant research trends over the past two decades. However, the clinical evidence remains mixed:

• One completed trial specifically examined PRP for acute and chronic ligament and tendon injuries
• A comparative study evaluated PRP as a treatment option for lateral epicondylosis
• Research on pectoralis major tendon repair showed outcomes both with and without PRP supplementation
• Some studies have explored systemic effects of PRP injection, though most focus on local tissue effects

Current Status:
Multiple ongoing trials are investigating PRP applications, including studies on degenerative disc disease and chronic knee osteoarthritis. The field appears to be actively evolving with standardization efforts around protocols and injection techniques.

Important Limitation: The available evidence suggests this remains an area of active investigation, with protocols still being refined. The heterogeneity in PRP preparation methods and injection techniques across studies makes it difficult to draw definitive conclusions about optimal treatment approaches.
