Assessment of proprioception improvement after anterior cruciate ligament reconstruction with tibial remnant preservation versus non remnant preservation

Abstract

Background: The ACL functions both as an anterior stabilizer and as a sensory organ. It is not only provides proprioceptive function, but also initiates protective and stabilizing muscular reflexes. Most ACLs are ruptured in the proximal half and most mechanoreceptors have been reported to be located in the sub-synovial layer near the tibial insertion of the ACL. Therefore, it is reasonable to preserve the remnant tissue. Particularly the tibial side, as a source of reinnervation if impingement and Cyclops can prevented. Objective: To compare proprioception after ACL reconstruction with remnant preservation versus non remnant preservation. Methods: This is a prospective single blind controlled randomized study was done from December 2015 to October 2017, it was conducted on forty patients (40 males). Divided into two groups twenty patients in each one to assess proprioception after anterior cruciate ligament reconstruction. Group (A) consisted of 20 patients with mean age 28±5.57 years who underwent to ACLR with tibial remnant preservation. Group (B) consisted of 20 patients with mean age 29.05±5.596 years who underwent to ACLR with non-remnant preservation were selected on the basis of clinical picture and imaging findings.
