The purpose of this study is to evaluate the safety profile and impact on functional results of surgical debridement performed in the early postoperative by comparing them with patients that undergone uncomplicated total joint arthroplasty. This is a retrospective case-control study. Patients that underwent debridement with prosthesis preservation for suspected acute postoperative infection of total hip or knee arthroplasty between 2010–2014 were included. Controls were randomly selected (1:2 ratio) from a list of primary arthroplasty patients in the same time period matching for articulation, age, gender, ASA score, BMI and follow-up time. Infection status, success of treatment and medical-surgical complications were investigated and all patients were assessed using Hip disability and Osteoarthritis Outcome Score(HOOS) or Knee injury and Osteoarthritis Outcome Score(KOOS).Aim
Method
Chronic back pain is a complex and poorly understood condition incorporating sensory, cognitive and emotional elements. Research demonstrates a strong association between chronic back pain and cognitive and non-cognitive factors such as anxiety, depression, fear-avoidance and self-efficacy. However, until very recently, the way in which chronic back pain sufferers process their emotions was largely unknown. To this end, we conducted two case-control studies using a between-groups correlational design to investigate the relationship between chronic back pain and emotional processing. In study 1, 55 chronic back pain sufferers and 55 pain-free individuals were administered the Emotional Processing Scale (EPS) to determine whether chronic back pain sufferers process their emotions differently from pain-free individuals. In study 2, 32 CBP sufferers and 27 pain-free individuals were administered the EPS, PHQ-9 and the GAD-7 to further test if chronic back pain is associated with altered emotional process and whether anxiety and depression may play a role in this relationship.Background and purpose of study:
