The Effect of Preoperative X/Y Ratio on Clinical Outcomes following Percutaneous Zadek Osteotomy for Insertional Achilles Tendinopathy.

ABSTRACT:

Background

The percutaneous dorsal closing wedge calcaneal Zadek osteotomy (ZO) is an effective treatment for patients with insertional Achilles tendinopathy (IAT), although consensus is lacking on ideal patient selection. Tourné et al proposed that a preoperative calcaneal X/Y ratio <2.5 defines surgical candidacy, but this criterion remains controversial. This study evaluated whether patients with IAT benefit from percutaneous ZO regardless of preoperative X/Y ratio.

Methods

A retrospective comparative study of 27 patients undergoing percutaneous ZO was performed. Patients were stratified into 2 cohorts based on preoperative X/Y ratio (<2.5 vs ≥2.5). Primary outcomes were PROMIS scores for pain, function, and mobility at 3, 6, and 12 months. Secondary outcomes included com
