Study summary

To evaluate the outcome of percutaneous paratenon release for chronic midportion Achilles tendinopathy.

Read the detailed description

Since 2011 the percutaneous procedure took the place of the open release of the paratenon for the surgical treatment for chronic midportion Achilles tendinopathy in the investigators' center. In this study the investigators re-evaluate the patients undergoing percutaneous surgery since then in order to compare the outcome with the excellent results cited in literature. The patients will be contacted and asked to participate completing a VAS-score, a VISA-A score and agreeing with a clinical examination.

Approving by the Ethical Committee of UZLeuven is pending.
