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.

Biodex results on both sides before 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.
Time frame: pre-surgery
Biodex results on both sides at 3 months
Isokinetic strength test conducted on both the injured and uninjured sides of the patients using the Biodex system 3 months after surgery.
Time frame: 3 months after surgery
Biodex results on both sides at 6 months
Isokinetic strength test conducted on both the injured and uninjured sides of the patients using the Biodex system 6 months after surgery.
Time frame: 6 months after surgery
