The use of tourniquet in total knee arthroplasty does not impact the functional outcome: a randomised controlled study.

Background: This study evaluates the clinical evidence for performing total knee arthroplasty (TKA) without a tourniquet, a shift from the near-universal use in 2009 to current trends towards tourniquet-less TKA in Norway and Sweden. This change is set against a backdrop of conflicting evidence regarding the positive and negative effects of tourniquet use.

Questions/purposes: The aims were to determine if the tourniquet has an impact on [1] Forgotten Joint Score-12 (FJS-12) at 8 weeks after surgery; [2] postoperative strength and function; [3] postoperative pain and opioid analgesic use; and [4] operative time, bleeding, and length of stay (LOS).

The tourniquet's effects on skeletal muscle during total knee arthroplasty.

This study investigates the impact of perioperative tourniquet on skeletal muscle cells during total knee arthroplasty (TKA) and its effects on the gene expression of apoptotic, inflammatory, and angiogenic pathways. The randomized controlled trial included 44 patients undergoing TKA. The patients were randomized to undergo surgery with (n = 23) or without (n = 21) tourniquet.

[Acute abdominal pain as cause of hospitalisation].

Background: Our aim was to investigate the extent, management and use of resources in patients admitted for acute abdominal pain.

Material And Methods: A prospective analysis of patients admitted as emergencies with acute abdominal pain of less than seven days duration was performed during two 3-month periods in 2000 and 2001.

Results: 483 patients, 262 women and 221 men with median age 50 years were registered.
