Functional Follow-up After Endoscopic Calcaneoplasty for Haglund's Deformity
Functional Follow-up After Endoscopic Calcaneoplasty for Haglund's Deformity
Isokinetic muscle strength test implemented by the Biodex system is a method used for
 evaluating muscle function that has been applied clinically in the field of sports and
 rehabilitation medicine. However, information on its application on Haglund's deformity
 remain insufficient. Therefore, the present study is designed to examine the effectiveness of
 the muscle strength test using the Biodex system in evaluating the recovery of athletic
 capacity in patients with Haglund's deformity following endoscopic surgery.
Patients. A retrospective (medical records), level 3 evidence study was designed to evaluate
 the outcomes of patients who underwent endoscopic surgery for Haglund's deformity. The
 present study was approved by the Peking University Third Hospital's ethics committee.
 Written informed consent was obtained from all patients, parents or guardians of the patients
 prior to the present study. The rights of the patients were protected.

 Diagnosis. Patients were designed to be diagnosed based on subjective complaints, combined
 with clinical and radiological examinations. Radiological measurements for this disease
 include the Fowler-Phillip angle, calcaneal pith angle, parallel pitch lines, Chauveaux-Liet
 angle and the X/Y ratio.
Inclusion Criteria:

 -  Patients who underwent endoscopic surgery for Haglund's deformity

 Exclusion Criteria:

 -  None
