Abstract

Purpose:The purpose of this study was to measure the active voluntary contraction distances of ruptured musculotendinous units during wide-awake tendon reconstruction surgery and to investigate the relationships between active contraction distance and the passive distraction distance and the time elapsed before reconstruction.Methods:The passive distraction distance and active contraction distance of 36 tendons of 22 patients who underwent forearm tendon transfer or tendon graft during wide-awake surgery were measured.Results:The passive distraction distance was significantly related to the active contraction distance of the ruptured musculotendinous unit (r = 0.60, P < 0.05). The passive distraction distance accounted for approximately half of the total excursion of the musculotendinous unit. There was no significant correlation between each distance and the time elapsed before reconstruction.Conclusions:The passive distraction distance was significantly related to the active contraction distance of the ruptured musculotendinous unit in vivo during wide-awake surgery. Active musculotendinous unit contraction distance may be a useful index to evaluate ruptured musculotendinous unit degeneration and donor muscle function in standard tendon reconstruction. This study suggested that the advantages of the wide-awake approach were not just as a clinical tool but also as an in vivo research tool.
