Abstract

BACKGROUND:

Chronic Achilles tendinosis is a relatively common but difficult orthopedic condition to treat. In this study, autologous platelet rich plasma (PRP), a concentrated bioactive blood component rich in cytokines and growth factors, was evaluated to determine its potential long-term efficacy in treating chronic cases of Achilles tendinosis resistant to traditional nonoperative management.

METHODS:

Thirty patients with chronic Achilles tendinosis who did not respond to a minimum of 6 months of traditional nonoperative treatment modalities were treated with a single ultrasound guided injection of PRP. AOFAS scoring was completed for all patients pretreatment and at 0, 1, 2, 3, 6, 12, and 24 months post-treatment. MRI and/or ultrasound studies were completed for all patients pre-treatment and at 6 months post-treatment. Prior to the PRP treatment all of the patients in this study were considering surgical Achilles repair for their severe symptoms.

RESULTS:

The average AOFAS score increased from 34 (range, 20 to 60) to 92 (range, 87 to 100) by 3 months after PRP treatment and remained elevated at 88 (range, 76 to 100) at 24 months post-treatment. Pretreatment imaging abnormalities present in the Achilles tendon on MRI and ultrasound studies resolved in 27 of 29 patients at 6 months post-treatment. Clinical success was achieved in 28 of 30 patients.

CONCLUSION:

Platelet-rich plasma was used effectively to treat chronic recalcitrant cases of Achilles tendinosis.
