Proprioceptive Isokinetic Repositioning, Functional Testing, and a Self-reported Questionnaire Before and After Anterior Cruciate Ligament Reconstruction

2019-08-17 19:30:34 | BioPortfolio


This prospectively study aims to evaluate the evolution of knee joint proprioception on isokinetic dynamometer before and after Anterior Cruciate Ligament (ACL) reconstruction and its relationships with muscle strength, self reported questionnaire and return to sport. This study will include 30 athletes with isolated ACL rupture, and treated with ACL reconstruction surgery and 15 healthy volunteers.


Anterior cruciate ligament (ACL) rupture is a common injury in athletes. It has multiple consequences on the knee: instability, pain, loss of muscle strength, proprioceptive impairments, modification of the knee kinematics and premature knee osteoarthritis. In athletes, the majority of these injuries are treated with ACL reconstruction surgery. The main objective of this treatment is the reduction of knee instability to allow return to sport, and this at the same level prior to the injury. Thus, the athlete's follow-up after the surgery is essential to guide the return to sport and to ensure that the knee sensorimotor control allows the return to sport. Currently this assessment is based primarily on functional testings and measurement of muscle strength.

The investigators propose to prospectively study the evolution of instrumentally measured knee proprioception using isokinetic dynamometer before and after ACL reconstruction as well as a study of the factors associated with its favorable evolution and its impact in the return to sport and its level.

Medical and Biotech [MESH] Definitions

The tear-forming and tear-conducting system which includes the lacrimal glands, eyelid margins, conjunctival sac, and the tear drainage system.

Sensory functions that transduce stimuli received by proprioceptive receptors in joints, tendons, muscles, and the INNER EAR into neural impulses to be transmitted to the CENTRAL NERVOUS SYSTEM. Proprioception provides sense of stationary positions and movements of one's body parts, and is important in maintaining KINESTHESIA and POSTURAL BALANCE.

Measurement of light given off by fluorescein in order to assess the integrity of various ocular barriers. The method is used to investigate the blood-aqueous barrier, blood-retinal barrier, aqueous flow measurements, corneal endothelial permeability, and tear flow dynamics.

The measurement around the body at the level of the ABDOMEN and just above the hip bone. The measurement is usually taken immediately after exhalation.

The measurement of magnetic fields generated by electric currents from the heart. The measurement of these fields provides information which is complementary to that provided by ELECTROCARDIOGRAPHY.
