Summary

A novel reconstructive surgery for chronic lateral ankle instability shows promising results. Most athletes returned to sport, with high satisfaction rates and minimal recurrence, particularly when degenerative changes were absent.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Anatomy

Background:

  • Chronic lateral ankle instability is a common condition, often leading to persistent pain and functional limitations.
  • Existing treatments may not fully restore stability or allow return to high-level athletic activity.
  • Recurrent instability after initial injury is a significant challenge for athletes.

Purpose of the Study:

  • To evaluate the efficacy of a new reconstructive surgical procedure for chronic lateral ankle instability.
  • To assess patient satisfaction and return-to-sport rates after the novel procedure.
  • To identify factors influencing surgical outcomes in patients with chronic lateral ankle instability.

Main Methods:

  • A cohort of 45 patients (47 ankles) with chronic lateral instability underwent a new reconstructive procedure.
  • The surgery involved lateral shifting of the capsule-ligament complex and advancement of the talocalcaneal ligament and inferior extensor retinaculum.
  • A retrospective review of 39 patients (39 ankles) was conducted at a mean follow-up of 4.6 years.

Main Results:

  • Excellent or good functional ratings were achieved in 34 out of 39 reviewed patients (87%).
  • Ninety-two percent (36/39) of patients reported satisfaction with the surgical outcome.
  • Thirty-four patients (87%) successfully returned to their preinjury level of sport, including 9 of 11 college athletes and 25 of 28 recreational athletes.

Conclusions:

  • The described reconstructive procedure is effective in treating chronic lateral ankle instability, leading to high patient satisfaction and successful return to sport.
  • Outcomes appear favorable, with low rates of recurrent instability, especially in the absence of pre-existing degenerative joint disease.
  • Pre-existing degenerative changes in the ankle may be associated with less favorable surgical results.
