Brief Summary

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.

Conditions

Haglund Syndrome; Insertional Achilles Tendinopathy

Keywords

insertional Achilles tendinopathy; Haglund Syndrome; endoscopic calcaneoplasty

Outcome Measures

Primary Outcomes (3)

• Victorian Institute of Sport Assessment-Achilles，VISA-A

  Evaluation of foot and ankle function. Higher scores indicate better function.

  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.

  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

  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

  perioperatively、after the surgery

• Height of Haglund deformity

  perioperatively、after the surgery

• BMI

  baseline

• Calcaneal X/Y ratio

  perioperatively、after the surgery

• age

Study Arms (2)

OPEN

Patients with Haglund syndrome and insertional Achilles tendinopathy treated with open calcaneoplasty.

ENDO

Patients with Haglund syndrome and insertional Achilles tendinopathy treated with endoscopic calcaneoplasty combined with insertional Achilles tendon reconstruction.

Eligibility Criteria

• Age: 18 Years - 80 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

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.

You may qualify if:

• : Patients had completed at least 12-month postoperative follow-up
• : Complete medical records and imaging findings were available

You may not qualify if:

• : Patients with previous Achilles tendon surgery.
• : Patients with missing medical records or imaging findings that precluded valid evaluation.
• : Patients deemed ineligible for enrollment by the investigators for other reasons.
