Abstract

PURPOSE: We analyzed the correlation of the Lysholm score, anterior displacement of tibia on stress radiography and muscle strength around the knee with postural control after anterior cruciate ligament reconstruction and also compared them with the normal subjects.
MATERIALS AND METHODS
Twenty-five patients after ACL reconstruction were evaluated with Lysholm knee score, anterior displacement on stress radiography with Telos, muscle strength around the knee with Biodex dynamometer and postural control with posturography.
RESULTS
The postural control had significant correlation with the Lysholm knee score & anterior displacement on stress radiography(r=0.565, r=0.783, p<0.01), but not with muscle strength around the knee(p>0.05). Patients group with 5mm instability under anterior displacement on stress radiography showed no significance compared with normal control group, while the group with instability more than 6mm showed significant differences in some conditions com- pared with control group.
CONCLUSION
Postural control after ACL reconstruction have significant correlation with Lysholm score and we presumed that the acquisition of mechanical stability of the knee after ACL reconstruction may be one of the important factors associated with the recovery of postural control by improvement of the proprioception.
