Surgical Management of Lateral Ankle Instability: Modified Broström-Gould Versus Arthroscopic Allograft Reconstruction of the Anterior Talofibular and Calcaneofibular Ligaments.

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. For this purpose, the clinical AOFAS (American Orthopedics Foot and Ankle Score) score will be used. The minimum value for the AOFAS score is 0 and the maximum value is 100. Higher scores on the AOFAS scale indicate a better outcome, meaning less pain, better function, and improved alignment.

Determine whether there are differences in health outcomes using the specific SP-36 (Short Form Health Survey) scale, is a 36-item questionnaire designed to measure health-related quality of life, it measures eight items: physical functioning, role limitations due to physical health, bodily pain, general health perceptions, vitality (energy/fatigue), social functioning, role limitations due to emotional problems and mental health. The score goes from 0 (worst health status) to 100 (best health status).

Determine whether there are differences in patient-perceived pain by using verbal numerical rating scale (VNRS). This score is widely used tool for assessing pain intensity, it measures pain from 0 (no pain) to 10 (worst paing imaginable).

Determine whether there are differences between both groups in the rate of postoperative complications, defined as: Delay or absence of surgical wound healing, superficial infection, deep infection, recurrence or persistence of instability, sural nerve and superficial peroneal nerve neuropathy and complex regional pain syndrome. They are all qualitative variables. They will be expressed in the categories: yes or no.

Determine whether there are differences in the time to return to normal life between the two surgical techniques. To do this, we will compare both groups in terms of time expressed in days.
