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. Our aims are to compare postural disorders after ligament reconstruction by hamstring tendon graft in the 3 months after surgery to those caused by aging. Materials and Method: 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. Conclusion: Postural alteration after ACL reconstruction on the injured leg and on bilateral posture can be compared to postural disorders caused by age.
Highlights
The rupture of the anterior cruciate ligament (ACL) is often traumatic and will cause a disturbance in the stability of the knee, highly requested articulation during the activities of the daily life and during the sport practice
Postural alteration after ACL reconstruction on the injured leg and on bilateral posture can be compared to postural disorders caused by age
Two groups of subjects participated in the study; a first of eleven asymptomatic subjects presenting no involvement in the lower limb and a second of seven subjects who had undergone ACL surgery with STG after isolated rupture of the ACL at three months postoperatively
Summary
The rupture of the ACL is often traumatic and will cause a disturbance in the stability of the knee, highly requested articulation during the activities of the daily life and during the sport practice. 87% of ACL surgery are uncomplicated [7] but it is possible to find joint, muscle, neuromuscular or proprioceptive. These changes will have an impact in the regulation of bipodal posture [8,9,10,11] and unipodal [12,13,14,15,16,17,18,19,20] statically and / or dynamically. 75.3% of people who have had surgery return to sport at the same level as before the injury and a certain percentage did not recover after one year due to lack of confidence, fear of recidivism, or by a feeling of instability [22]
