Abstract
Objectives
The study aims to determine whether an arthroscopic ligament reconstruction is necessary to relieve clinical ankle instability symptoms in patients with an MRI scan showing medial or lateral ligament tear.
Methods
This was a single centre retrospective case series study of 25 patients with ankle instability and ligament tear on MRI scan who had undergone arthroscopic procedures from January 2015 to December 2018. Patients were followed up for an average period of 3 years postoperatively to check for any recurrence of symptoms
Results
Of the 25 patients, 23 had ATFL tear on MRI scan, and 2 had deltoid ligament tear. Examination under anaesthesia was stable in 13 patients and unstable in 12 patients. The majority of the patients (76%) had a simple arthroscopic ankle debridement and no ligament repair. Six patients needed Brostrom repair.
Conclusions
Our study has shown that in patients with MRI proven ligament tear and clinical instability, a ligament reconstruction was unnecessary in most patients. The instability symptoms of patients were relieved by simple ankle arthroscopic debridement.
