Assessing Preoperative Pain Sensitivity Predicts the Postoperative Analgesic Requirement and Recovery after Total Knee Arthroplasty: A Prospective Study of 178 Patients.

Background: The aim of this article is to study the correlation between preoperative pain sensitivity and postoperative pain and analgesic requirements for patients undergoing primary total knee arthroplasty.

Methods: Between December 2018 and April 2019, the pain sensitivity of 178 consecutive patients undergoing primary total knee arthroplasty was assessed preoperatively with a digital algometer. The patients reported the VAS (visual analog scale) score at 3 instances of needle prick (phlebotomy, glucometer blood sugar, intradermal antibiotic test dose), during the range of movements and completed the Depression Anxiety Stress Scale score.

Lag screw with DHS (LSD) for vertical angle femoral neck fractures in young adults.

Vertical Pauwels Type III fractures of the neck of femur in young patients are difficult fractures to treat. These are usually as a result of high energy trauma which are associated with a significant degree of fracture comminution in the neck of femur. This makes the fracture reduction and fixation difficult.
