Summary

Primary Objective:

To clarify whether arthroscopic reconstruction with allograft provides tangible benefits over the modified open Broström-Gould technique, or if both are equivalent in efficacy and safety. The clinical AOFAS scale will be used for assessment.

Secondary Objectives:

To determine if there are differences in health outcomes and patient-perceived pain using the specific SP-36 scale and verbal numeric rating scale (VNRS). Additionally, to assess differences in postoperative complication rates and time to return to daily life activities between the two surgical techniques.

Study Design:

Prospective, randomized, controlled clinical trial with two parallel groups stratified by age and functional demand.

Condition or Disorder Being Studied:

Chronic lateral ankle instability.

Study Population and Sample Size:

The target population includes subjects diagnosed with chronic lateral ankle instability. The study population consists of patients diagnosed in the Orthopedics consultations at Hospital Infanta Elena who meet the inclusion and exclusion criteria. Based on sample size calculations, a total of 36 patients will be recruited. However, due to the prospective nature and stratification by epidemiological and functional variables, the sample size may be increased to ensure comparable groups in each stratum.

Study Timeline and Estimated Completion Date:

The study is expected to begin in the third quarter of 2025. Recruitment is estimated to last 24 months, with a follow-up period of 12 months, for a total duration of 3 years, ending in the third quarter of 2028.

Conditions

  • Ankle Sprain

Interventions

PROCEDURE

Arthroscopic reconstruction surgery

Arthroscopic reconstruction with allograft, in which a tendon (generally from a tissue bank) is used to reconstruct the ligaments. This technique is performed through small incisions using arthroscopy.

PROCEDURE

Open surgery

Open surgery consists of the modified Broström-Gould technique, which allows for the reconstruction of damaged ligaments using the patient's own tissues through an incision on the lateral side of the fibula. This technique has shown satisfactory functional results.
