探討前十字韌帶缺損後經由內視鏡韌帶重建術後其膝關節本體自覺功能性評估

Evaluation of Knee Proprioception after Arthroscopic ACL Reconstruction Using Bone-Patellar-Tendon-Bone Graft

摘要


Ligaments play a major role in normal joint kinematics, providing mechanical restraint to abnormal joint motion when a stress is placed on the joint. Following injury to the anterior cruciate ligament (ACL) is thought to disrupt joint afferent sensation and result in proprioceptive deficits. The primary concern of the orthopedic surgeon has been the mechanical restoration of this ligament following injury, or post reconstructive surgery, in attempt to reestablish the joint's static stability and kinematics. Proprioception is considered a specialization variation of the sensory modality of touch, which encompasses the dynamic and static sensation of joint motion (kinesthetic sensibility) and position (joint position sensibility), respectively. To investigate this problem, 10 patients were studied at an average of 11.2 mouths after arthroscopy ACL reconstruction with BPTB. The kinesthetic sensibility was measured by establishing the threshold to detection of passive motion (TTDPM) and joint position sensibility was assessed by reproduction of passive positioning (RPP). A proprioceptive testing device (PTD) which was designed to assess joint propriocetion. Results revealed no significantly decrease Kinesthetic awareness in the ACL reconstructed knee versus the uninvolved knee. Lastly, we found that surgery combined with rehabilitation may restore some, if not all, of the proprioceptive sensibility and may ultimately improve function and prevent the recurrent symptoms.
