  • Severity of Chronic Knee Pain After Total Knee Replacement Rochester, Minn.

    The prevalence of chronic pain following total knee replacement has been under studied.  In recent years, the perioperative use of multimodal analgesic strategies including regional anesthetic techniques has substantially improved early postoperative pain management. However, it is not clear that these improvements in perioperative care have reduced the frequency of chronic pain post-total knee replacement.  This study will conduct a cross sectional study to determine the prevalence of chronic knee pain following total knee replacement up to 5 years postoperatively.  This study will also identify risk factors, such as smoking, depression, and pain problems elsewhere as predictors of chronic knee pain after knee replacement.
