Evaluating a new hydrogel to prevent adhesions after ankle ligament surgery

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to assess the effectiveness of a novel crosslinking hyaluronan hydrogel in preventing adhesions following anterior talofibular ligament repair surgery. Participants will be randomly assigned to receive either the hydrogel or a sham treatment, with the expectation that those receiving the hydrogel will experience improved range of motion in their ankle. The study focuses on patients with confirmed anterior talofibular ligament injuries who have not responded to conservative treatments. The trial will monitor outcomes related to adhesion formation and functional recovery post-surgery.

Inclusion Criteria:

1.1 Voluntarily participate and sign an informed consent form; 1.2 Age 18 to 60 years of male or female; 1.3 Patients experiencing lateral ankle pain discomfort, confirmed by MRI to have anterior talofibular ligament (ATFL) injury; 1.4 History of recurrent ankle inversion sprains three times or more, with no improvement after six months of conservative treatment, and scheduled for ATFL repair surgery; 1.5 Willing to comply with all follow-up requirements of the trial protocol.

Exclusion Criteria:

2.1 Severe ankle osteoarthritis; 2.2 Patients with a history of ankle fracture or surgery; 2.3 Undergoing foot- or ankle-related treatments that may affect the trial results; 2.4 Presence of skin infection, skin defects, or need for skin grafting at the surgical site; 2.5 Uncontrolled chronic diseases, such as diabetes mellitus; 2.6 Presence of autoimmune diseases (such as Autoimmune Collagenopathy, rheumatoid arthritis), malignancies, coagulation disorders, heart diseases, psychiatric illnesses, or other conditions that may pose higher risks to patients in the trial; 2.7 Use of corticosteroids within the past 6 months, systemic corticosteroids within the past month, immunosuppressive drugs within the past 3 months, or daily use of non-steroidal anti-inflammatory drugs (NSAIDs) within the past week, or occasional use within 8 hours (patients using nasal/inhaled corticosteroids may be considered for inclusion) ; 2.8 Clinically significant coagulation abnormalities or undergoing anticoagulant therapy within 10 days before surgery or currently taking anticoagulant drugs; 2.9 Known allergy to sodium hyaluronate or any components of medical devices;allergy to Gram-positive bacterial protein or streptococcal protein；or other severe allergic history deemed unsuitable for participation by the investigators; 2.10 Pregnant, lactating women, or women planning to become pregnant during the trial period; 2.11 Other conditions deemed unsuitable for participation by the investigators.
