An observational study in Haglund Syndrome and Insertional Achilles Tendinopathy, sponsored by Nanjing First Hospital, Nanjing Medical University. Not yet recruiting at 1 site in China. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-10-21.
Sponsored by Nanjing First Hospital, Nanjing Medical University · Observational
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.
Nanjing First Hospital, Nanjing Medical University is the lead sponsor of 220 studies on the registry; 107 are open to participants now.
Counted across the registry records on this site, refreshed daily.
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.
