Functional Follow-up After Endoscopic Calcaneoplasty for Haglund's Deformity

Completed

• Conditions: Haglund's Deformity
• Interventions: Other: Classification statistics

• Registration Number: NCT04471259
• Lead Sponsor: Peking University Third Hospital

Brief Summary

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.

Detailed Description

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.

Arm && Interventions

Group	Intervention	Description
Patients' uninjured side	Classification statistics	The Biodex, AOFAS, VAS were tested on the patients' uninjured side
Patients' injured side	Classification statistics	The Biodex, AOFAS, VAS were tested on the patients' injured side

Primary Outcome Measures

Name	Time	Method
Biodex results on both sides before surgery	pre-surgery	Biodex isokinetic muscle testing system was applied in this research. Isokinetic muscle strength test is a kind of muscle function evaluation and test method, which has been applied in the research and clinical work of sports medicine and rehabilitation medicine but never on Haglund's disease before. The isokinetic muscle strength test of the flexor and dorsiflexion of the ankle joint can evaluate the muscle strength and endurance to reflect the postoperative patient's capacity for action, providing reliable clinical evidence for postoperative rehabilitation of patients after endoscopic calcaneoplasties. Isokinetic strength test conducted on both the injured and uninjured sides of the patients using the Biodex system before surgery.
Biodex results on both sides at 3 months	3 months after surgery	Isokinetic strength test conducted on both the injured and uninjured sides of the patients using the Biodex system 3 months after surgery.
Biodex results on both sides at 6 months	6 months after surgery	Isokinetic strength test conducted on both the injured and uninjured sides of the patients using the Biodex system 6 months after surgery.
