The Technique

The procedure targets the interface between the patellar tendon and Hoffa’s fat pad, not the tendon itself. Using ultrasound guidance, a needle is used to mechanically separate this plane, disrupting neovessels and nerve ingrowth thought to drive pain.

This aligns with the broader “neovascular pain” model popularized in Achilles work and more recent patellar tendon interventions. Learn more here.

Key Findings

1. Patients Demonstrated Meaningful Clinical Improvement

At final follow-up (~13 months):

• 83% of patients achieved clinically significant improvement
• Mean VISA-P improvement: +53 points

That magnitude of change is notable, especially in a chronic, treatment-resistant population.

2. Patients Demonstrated Rapid Return to Sport

One of the more compelling findings:

• All competitive athletes returned to sport within 1 month

This makes scraping particularly interesting for in-season athletes.

3. Favorable Safety Profile

• No major complications reported
• Procedure is performed outside the tendon, preserving structural integrity

By targeting this interface, scraping offers a mechanism-based interventio, minimal disruption of tendon structure, and offers a bridge between conservative care and surger.

Bottom Line

Baria et al. provides early but compelling evidence that tendon scraping may offer meaningful symptom relief with rapid recovery and low risk. While larger studies are needed, this technique represents a promising addition to the treatment algorithm for chronic patellar tendinopathy, especially when traditional approaches fall short.
