Quadriceps Strain and TKA: Contribution of the Tourniquet and Intramedullary Rod to Postoperative Thigh Pain: A Randomized Controlled Trial.

Background: Thigh pain is relatively common after total knee arthroplasty (TKA) and has been attributed to compression of the thigh muscles by the tourniquet used during surgery. Thigh pain that occurs after a TKA that was performed without a tourniquet may be due to a strain of the quadriceps muscle or insertion of the intramedullary (IM) rod. The purpose of the present study was to determine the cause of thigh pain after TKA in a randomized controlled trial evaluating tourniquet use, IM rod use, and quadriceps strain.

Wrist Hemiarthroplasty of Irreparable Distal Radius Fracture under Wide-Awake Local Anesthetic and No Tourniquet.

Distal radius fractures (DRF) are common in elderly patients and the incidence continues to increase with the aging of the population. For irreparable fractures in the elderly, treatment with a reduction cast leads to unreliable results and frequent complications when treated with an anterior plate. Recent studies on hemiarthroplasty for elderly complex wrist fractures have resulted in good clinical and radiologic outcomes, as well as high satisfaction rates.
