Influence of Anterior Cruciate Ligament surgery with semitendinous and gracilis graft on static postural balance at 3 months postoperatively: Randomized controlled study

Abstract: Introduction: The anterior cruciate ligament (ACL) tear is the most common sport injury. Surgery is often proposed, but single-leg and double-leg static postural disorders have been discovered several months after surgery. Objective: To compare postural disorders after ligament reconstruction by hamstring tendon graft in the 3 months after surgery to those caused by aging and to determine the influence of vision and of knee position in postural control. Materials and Methods: 2 groups of subjects underwent bilateral and unilateral postural tests. An analysis of the centre of pressure’s displacement is carried out for each test. Results: Comparaison of the two groups shows no significant difference for the injured leg on the unilateral and bilateral tests only. There is a significative difference for the closed-eyes unilateral tests and the bent-knee bipodal tests of the ACL group. Conclusion: Postural alteration after ACL reconstruction on the injured leg and on bilateral posture can be compared to postural disorders caused by age. Vision seems to be used in postural control. Postural alteration seems most important in the bilateral bent-knee testACL surgery. He specializes in the field of laximetric assessment, isokinetic assessment, gait and postural analysis to determine risk factors related to sports recovery after ACL surgery. He is also teacher in several insitutes in various fields of rehabilitation and publishes many articles on lower limbs rehabilitation.
