The proprioception of the knee joint following tibia plateau fractures

Proprioception is a conscious and/or unconscious perception of position change in an extremity or joint in space. In our study our purpose was to evaluate whether the lower extremity proprioception in long term, is altered following tibia plateau fractures and to assess its relation with age and type of fracture. This retrospective study includes the evaluation of proprioception in 38 tibia plateau fracture patients (29 male, 9 female) of various types who were operated with open reduction and internal fixation (ORIF) technique in our clinic, by comparison of both operated knee and unaffected knee. The mean age of the patients were 38,8 (range, 20-60) and mean follow-up time was 56 months (range, 13-120 months). Proprioception measurements were assessed at 30° and 60° of knee flexion degrees both passively and actively. There were no significant difference between the operated knee and unaffected knee by mean absolute angular deviation values at passive (p = 0,22) or active 60° (p = 0,22). Accordingly passive (p = 0,47) and active 30° (p = 0,62) mean absolute angular deviation values showed no significant difference. Our study has indicated that proprioception at the operated extremity is not significantly different from the unaffected knee in tibia plateau fractures at long term follow-up.
