Study population: Patients diagnosed with Haglund syndrome and insertional Achilles tendinopathy who received surgical treatment in our hospital. Subjects were retrospectively screened according to inclusion and exclusion criteria and divided into two groups based on surgical approach. Both groups underwent calcaneoplasty combined with insertional Achilles tendon reconstruction, one via open approach and the other via endoscopic approach.
Inclusion Criteria:1: Patients attended the orthopedic outpatient clinic of Nanjing First Hospital and underwent open or endoscopic calcaneoplasty combined with Achilles tendon insertion reconstruction between 2019 and 2026.
2: Patients had completed at least 12-month postoperative follow-up
3: Complete medical records and imaging findings were available
-
Exclusion Criteria:1: Patients with severe Achilles tendon injury or complete rupture.
2: Patients with previous Achilles tendon surgery.
3: Patients with missing medical records or imaging findings that precluded valid evaluation.
4: Patients deemed ineligible for enrollment by the investigators for other reasons.

About this study
Official title: Open Versus Fully Endoscopic Calcaneoplasty With Achilles Tendon Insertional Reconstruction for Haglund Syndrome: A Retrospective Comparative Study
This project intends to retrospectively review the medical records of patients with Haglund's syndrome who underwent surgical treatment in the Department of Sports Medicine and Joint Surgery between 2019 and 2026, to analyze the advantages and limitations of totalendoscopic calcaneoplasty combined with Achilles tendon insertion reconstruction compared with conventional open surgery. The findings are expected to provide scientific evidence for individualized treatment of patients with Haglund's syndrome.

What is being measured
The primary outcome is the main question the study is designed to answer.
Victorian Institute of Sport Assessment-Achilles，VISA-A
Evaluation of foot and ankle function. Higher scores indicate better function.
Measured: pre-surgery, 1-month after the surgery, 3-month after the surgery, 6-month after the surgery, 12-month after the surgery
American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale
Evaluation of foot and ankle function. Higher scores indicate better function.
Measured: pre-surgery, 1-month after the surgery, 3-month after the surgery, 6-month after the surgery, 12-month after the surgery
visual analogue scale，VAS
The visual analogue scale (VAS) is a pain assessment scale, in which lower scores indicate less severe pain
Measured: pre-surgery, 1-month after the surgery, 3-month after the surgery, 6-month after the surgery, 12-month after the surgery
Secondary outcomes (5)
Fowler-Philip angle
The Fowler-Philip angle was measured on radiographic images in degrees
Measured: perioperatively、after the surgery

BMI
weight and height will be combined to report BMI in kg/m^2
Measured: baseline
Calcaneal X/Y ratio
The Calcaneal X/Y ratio was measured on radiographic images
Measured: perioperatively、after the surgery
