Modified Brostrӧm Procedure With and Without Possible Arthroscopy for Lateral Ankle Instability
Lateral Ankle Instability
About this trial
This is an interventional other trial for Lateral Ankle Instability
Eligibility Criteria
Inclusion Criteria:
- Able to independently consent for surgery
- Able to demonstrate an understanding of study procedures
- Adult patient 18 years of age or older
- All active duty soldiers, Veterans, dependents
- Ability to comply with study procedures for the entire length of the study
- Presence of lateral ankle instability meeting operative criteria listed in 6.2.1 with documented failed conservative measures such as: physical therapy, ankle braces, and rest
Exclusion Criteria:
- Unable to obtain medical clearance for surgery
- Recent (1 month) febrile illness that precludes or delays participation
- History of or suspected of drug/alcohol abuse, as these patients may not be compliant with physical therapy. All patients are required to be immobilized for 6 weeks after surgery
- Pregnant women, this is an elective procedure and a MBP or ankle arthroscopy is not typically offered to pregnant women. Screening for pregnancy is done as part of standard of care

MBP plus ankle arthroscopy (Group A)
MBP alone (Group B)
Group A will receive a diagnostic ankle arthroscopy followed by the Modified Brostrӧm Procedure (MBP). In the ankle arthroscopy, multiple pictures are taken inside of the joint to note possible pathologic processes (for example - osteochondral lesions of the talus). Ankle arthroscopy involves one incision in the middle of the ankle anteriomedial (middle) incision and one incision on the outside of the ankle. Each incision (a small cut in the skin) is roughly 5mm in length (which is about 0.2 inches). After the incision is made, the participant will receive a diagnostic ankle arthroscopy.If the surgeon detects an abnormality inside the joint, he will operate on the abnormality with the arthroscope according to the generally accepted principles for treating the abnormality.
Group B will receive sham skin incisions on the ankle a Modified Brostrӧm Procedure (MBP) alone (that is, there will be no diagnostic ankle arthroscopy) followed by the Modified Brostrӧm Procedure (MBP). If a participant is assigned to Group B, the participant will receive two small superficial skin incisions at the sites where the investigators would normally insert instruments for the ankle arthroscopy. As with Group A, there will be one anteriomedial (middle) incision on the middle of the ankle and one anteriolateral (side) incision to on the outside of the ankle. Each incision will be roughly 5mm in length and 5 mm in depth, but will not violate subcutaneous tissue. The width of these incisions will be the width of the blade, at 1mm. However, unlike Group A, the participants in Group B will not have any instruments inserted into their ankle and will not have any operation to repair or remove damaged tissue.
