ABSTRACT

Objective:

To investigate any changes in proprioception or grey matter volume (GMV) after anterior cruciate ligament (ACL) rupture.

Methods:

Eighteen male patients with right-side ACL rupture (diagnosed through clinical examination and MRI) and healthy right hand function constituted the case group, while another 18 right-handed healthy counterparts were enrolled as the control group. Proprioception, balance and functional performance were assessed for both groups using the anteroposterior shift of the tibia (APST), an active angle reproduction test (AART), a modified star excursion balance test (mSEBT) and single-leg hop distance (SHD). MRI (at 3.0T) was used to collect the brain structure images and SPM8 software was used to perform voxel-based morphometry. Any correlation between changes in function and GMV were analyzed.

Results:

Significant differences were observed between the two groups in their average APST, AART, SEBT and SHD scores. Compared with the healthy controls, the average volume of grey matter in the cerebelum-crus1-L was significantly larger in the case group, while their Supp_Motor_Area_R, Parietal_Sup_R, Parietal_Inf_R, Caudate_R and ParaHippocampal_R grey matter volumes were significantly smaller. Among the case group, the average volumes of their Supp_Motor_Area_Rs, Parietal_Sup_Rs, Parietal_Inf_Rs, and Caudate_Rs were negatively correlated with their mSEBT scores.

Conclusions:

The brain′s structure changes after ACL rupture and neuromuscular control becomes impaired. The cortical motor control strategy shifts to subcortical motor control after ACL rupture. The mSEBT can reflect indirectly the changes in brain structure plasticity after ACL rupture.
