Ligamentoplasty of the Ankle Periosteum Known as Roy-Camille/Saillant at the Orthopedic Traumatology Department of the Pau Hospital Center (France)

Introduction: Chronic ankle instability comprises two main entities, often associated with mechanical instability due to ligament and/or bone trauma, and functional instability due to a postural or proprioceptive defect. Periosteal ankle ligamentoplasty is a widely used technique in France. The aim of our study was to evaluate the functional result after a ligamentoplasty technique on the periosteum known as Roy-Camille/Saillant. Methods: A retrospective study of 264 months which involved 21 patients including 3 women and 18 men with a sex ratio of 6 with a mean age of 38.71 (25 - 58) years. Patients were included who benefited from a Roy-Camille/Saillant periosteal ligamentoplasty for chronic ankle instability and had accepted for the completion of an evaluation form. Fourteen were reviewed clinically and radiologically. We have an assessment sheet taking into account pain, function and alignment. The rearfoot AOFAS score indicates excellent (90 - 100), good (80 - 89), fair (70 - 79), and poor (<69). Results: A minimum follow-up of 8 months and an average follow-up of 7 years (8 months to 18 years). 93% had a painless and stable ankle, and 86% returned to sport. The mean postoperative AOFAS score was 97 (87 - 100), (86%) patients believed their ankle was more stable after surgery, (14%) did not feel any difference. 11 patients were very satisfied, 3 satisfied. Among the 11 satisfied with the operation, two (2) people complained of a sensitivity disorder. One patient presented with hypoaesthesia in the superficial peroneal nerve territory. Nine of them felt no difference between their right and left ankle. Conclusion: The satisfaction rate was 93%, and the results obtained in our study are in agreement with other techniques and previous publications on similar procedures.
