The anterior mini-open approach for femeroacetabular impingement: Gait and functional assessment at one year post-surgery
Abstract
This study aimed to evaluate the outcome of the anterior mini-open approach of the hip for femoroacetabular impingement (FAI) at one year post-surgery by use of questionnaires, functional capacity tests and biomechanical studies. This is a case series prospective study. A total of 14 patients diagnosed of FAI were included. Patients were classified according to Tönnis scale. Hip joint mobility, Faber distance, pain levels (assessed on a visual analogic scale [VAS]), 6-minute walking test (6MWT), Timed up & go test (TUGT), Stairs climbing test, Lequesne functional index, and gait analysis were assessed prior to and 12 months after surgery. Pain significantly improved following surgery. An improvement of 80% or more was found in 6 patients (42.85% of cases). Improvements were also seen in time support of the affected limb and in the braking force of the contralateral limb, although these are not clinically significant. No statistically significant changes were seen in functional capacity tests. At 12 months after surgery, meralgia paraesthetica presented in 3 patients (21.4%), and a total hip arthroplasty was performed in 1 patient. There was significant reduction in pain intensity 12 months following mini-open approach for FAI c...Continue Reading

Biomechanics
Biomechanics examines the generation of internal forces within the body and investigates the effects and control of forces that act on or are produced on tissues. Here are the latest discoveries.
