May 18, 2026 updated by: Jiang Dong, Peking University Third Hospital

Comparison of Modified Broström Repair + Suture Tape and Modified Broström Repair for Chronic Lateral Ankle Instability : A Prospective Cohort Study

GJL is a risk factor for postoperative recurrent instability following an MBR for CLAI. Additional suture tape augmentation has been suggested to provide more strength and stability. However, the outcomes of the MBP with suture tape augmentation were unknown, which requires further exploration.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Generalized joint laxity (GJL) is a risk factor for postoperative recurrent instability following an open modified Broström repair (MBR) for chronic lateral ankle instability (CLAI). MBR with suture tape augmentation may provide more strength and stability. However, BPR with suture tape augmentation may lead to rejection of the suture tape. In addition, the outcomes of the MBP with suture tape augmentation were unknown.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult

Accepts Healthy Volunteers

No

Sampling Method

Probability Sample

Study Population

The patients who go to visit a doctor for persistent lateral ankle pain and instability over three months and invalid conservative treatment, with the age of 15 - 55 years. If the Beighton score of the patient is ≥4 and the exclusion criteria are met, he or she is going to be advised to participate in this study.

Description

Inclusion Criteria:

  • Clinical diagnosis of lateral ankle instability
  • Beighton score ≥4
  • Age with 18 to 60 years

Exclusion Criteria:

  • Patients with an acute or subacute ankle injury
  • Injury of the deltoid ligament
  • Alignment of lower extremity greater than 5 degrees
  • Fractures of the lower extremity
  • Stage III or IV osteoarthritis
  • Patients who refused to participate in the study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The American Orthopaedic Foot and Ankle Society (AOFAS) score
Time Frame: postoperative AOFAS score at 1 year
This score is a primary scale for lateral ankle instability, ranges from 0-100, and the higher of the score is associate with a better outcome.
postoperative AOFAS score at 1 year
The American Orthopaedic Foot and Ankle Society (AOFAS) score
Time Frame: postoperative AOFAS score at 2 years
This score is a primary scale for lateral ankle instability, ranges from 0-100, and the higher of the score is associate with a better outcome.
postoperative AOFAS score at 2 years
The American Orthopaedic Foot and Ankle Society (AOFAS) score
Time Frame: postoperative AOFAS score at 6 months
This score is a primary scale for lateral ankle instability, ranges from 0-100, and the higher of the score is associate with a better outcome.
postoperative AOFAS score at 6 months
The American Orthopaedic Foot and Ankle Society (AOFAS) score
Time Frame: postoperative AOFAS score at 3 months
This score is a primary scale for lateral ankle instability, ranges from 0-100, and the higher of the score is associate with a better outcome.
postoperative AOFAS score at 3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Anterior displacement and talar tilt angle in stress radiography
Time Frame: postoperative radiographic measures at 2 years
The outcomes are common indicators for evaluation the lateral stability of ankle, and can be evaluated through same stress radiography
postoperative radiographic measures at 2 years
Rate of re-injury
Time Frame: the rate of re-injury at 2 years
The rate of patients re-sprain after the surgery
the rate of re-injury at 2 years

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Signal to noise value of anterior talofibular ligament
Time Frame: 6 months post-treatment
Signal to noise value of the anterior talofibular ligament
