Sleep Disturbance Strongly Related to the Development of Postoperative Delirium in Proximal Femoral Fracture Patients Aged 60 or Older.

Purpose: Post-fracture sleeping disorders can lead to a deterioration of mental and physical health and delay recovery to pre-fracture status. Here, an analysis was conducted to determine if sleep disturbance is a risk factor for delirium in patients older than 60 years of age with surgically treated proximal femoral fractures.

Materials And Methods: This retrospective study included 316 patients with surgically treated proximal femoral fractures between January 2014 and December 2016; 33 patients were removed from analysis due to exclusion criteria.

Advantages of the experience of navigation when starting manual total knee arthroplasty.

Purpose: To evaluate how the accuracy of coronal-plane bone cutting and operative time may be affected by the experience of navigated total knee replacement (TKR) in starters of manual TKR.

Methods: We analyzed 30 cases of navigated TKR performed in the early years (group 1), 30 consecutive cases of navigated TKR performed after experiencing more than 100 cases of navigated TKR (group 2), and the initial 30 consecutive cases of manual TKR (group 3). Postoperative mechanical hip-knee-ankle (mHKA) angle, mechanical medial proximal tibial angle (mMPTA), and mechanical lateral distal femoral angle (mLDFA) were measured.
