Abstract
Background: In patients with lateral ankle instability (LAI) and attenuated ligament tissue quality, the stability of lateral ankle can be achieved through percutaneous inferior extensor retinaculum augmentation (PIERA). This study is aimed to compare the functional outcomes of PIERA with gold standard Modified Broström Procedure (MBP) for patients with LAI.
Methods: Twenty participants were allocated to PIERA and MBP treatment group according to the intraoperative arthroscopic assessment of lateral ankle ligament, with each group comprises 10 participants. Patients were assessed using American Orthopaedic Foot and Ankle Society score, Cumberland ankle instability tool, Foot and Ankle Ability Measure, star excursion balance test (SEBT), and a stair descent gait analysis, a day prior to surgery and one year postoperatively. Operative outcomes and variables during stair descent were documented and compared between the preoperative and postoperative patients, and between treatment groups.
Results: The PIERA procedure significantly promoted the clinical outcomes of the patients with LAI. The anterior reach of SEBT was increased from 79.1 ± 12.6 to 84.8 ± 12.9 (p = 0.034). The PIERA procedure significantly increased ankle flexion range of motion (p = 0.049), maximal ankle dorsiflexion (p = 0.009), and peroneal activation post-initial-contact (p = 0.002) and during the gait cycle (p = 0.015). The effects of PIERA and MBP on ankle function were not significantly different.
Conclusion: PIERA produces similar functional outcomes compared with MBP in promoting clinical outcomes, dynamic postural stability, peroneal activation, and ankle sagittal range of motion for patients with LAI.
Level of evidence: III, retrospective cohort study.
期刊介绍：
Foot and Ankle Surgery is essential reading for everyone interested in the foot and ankle and its disorders. The approach is broad and includes all aspects of the subject from basic science to clinical management. Problems of both children and adults are included, as is trauma and chronic disease. Foot and Ankle Surgery is the official journal of European Foot and Ankle Society.
The aims of this journal are to promote the art and science of ankle and foot surgery, to publish peer-reviewed research articles, to provide regular reviews by acknowledged experts on common problems, and to provide a forum for discussion with letters to the Editors. Reviews of books are also published. Papers are invited for possible publication in Foot and Ankle Surgery on the understanding that the material has not been published elsewhere or accepted for publication in another journal and does not infringe prior copyright.
