Abstract:
OBJECTIVE:To explore clinical effects of single-tunnel pullout structure fixation and anatomical reconstruction of lateral ligament complex in treating chronic lateral ankle instability.
METHODS:From January 2016 to December 2018, clinical data of 23 patients with chronic lateral malleolus instability who underwent anatomical reconstruction of lateral malleolus ligament complex with single-tunnel pullout structure fixation, were retrospectively studied. Among them, including 7 males and 16 females, aged from 17 to 33 years old with an avergae of (26.0±4.3) years old;16 patients classified to grage 0, and 7 patients classified to gradeⅠaccording to Kellgren-Lawrence(K-L) grading;the time of sprain ranged form 2 to 15 with an average of (5.7±2.9) times;the time from injury to operation ranged to 4 to 18 months with an average of (9.0±3.3) months. The range of movement of operative and uninjured ankle joints were measured at 24 months after opertaion, visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society (AOFAS) were used to evaluate ankle joint function and improvement of pain, K-L grading and MRI scoring of osteoarthritis of ankle (MSOA) were used to evaluate degree of cartilage degeneration of ankle joint.
RESULTS:All patients were followed up from 24 to 48 months with an average of (33.4±6.7) months. All the anterior talofibular ligaments and calcaneofibular ligaments were dissected and reconstructed by single-tunnel pullout structure fixation. The range of motion of dorsiflexion, plantarflexion, varus, and valgus on the operative side of ankle joint were smaller than those on the healthy side. There were no statistically differences in dorsiflexion and eversion between operative side and healthy side of ankle joint (
CONCLUSION:Treatment of chronic lateral ankle instability with reconstruction of lateral ligament complex with single-tunnel pullout structure fixation could provide better tendon and bone healing conditions, improve surgical safety and could achieve satisfactory clinical outcomes.
