Diagnosis and treatment of intraoperative popliteus tendon impingement.

Herein, we describe a simple, effective strategy for diagnosing and treating intraoperative popliteus tendon impingement during total knee arthroplasty (TKA). When lateral impingement is detected intraoperatively during TKA, manual isolation of the popliteus tendon can help determine the cause. Using this technique, the etiology of intraoperative lateral impingement during TKA was never misdiagnosed and the popliteus tendon was never unnecessarily released.

Pharmacologic risk factors for post-operative delirium in total joint arthroplasty patients: a case-control study.

Total joint arthroplasty (TJA) patients are at increased risk of post-operative delirium (POD) given their demographics and functional impairment. Certain pharmacologic agents are known to cause delirium, but those that cause delirium following TJA are unknown. Our aim was to explore if specific anesthetic agents, opiate pain medications, or benzodiazepines are associated with POD following TJA.
