Quadriceps Strain and TKA: Contribution of the Tourniquet and Intramedullary Rod to Postoperative Thigh Pain

“…The literature does not point to a cause for pain in the thigh after TKA, other than the use of a tourniquet 3 . Possible causes of thigh pain after TKA that are not related to the use of a tourniquet include an iatrogenic strain of the quadriceps muscle during the procedure, microtrabecular fracture caused by placement of the intramedullary (IM) rod into the femoral canal, and neurologic causes (e.g., neuritis resulting from spinal anesthetic or femoral or adductor canal nerve blocks or meralgia parastetica 4 ).…”

“…In approximately 5% of patients, thigh pain due to a quadriceps strain was more bothersome than knee pain following TKA. n Gregory W.
