The effect of continuous adductor canal block combined with distal interspace between the popliteal artery and capsule of the posterior knee block for total knee arthroplasty: a randomized, double-blind, controlled trial.

Background: The optimal analgesia for total knee arthroplasty (TKA) requires excellent analgesia while preserving muscle strength. This study aimed to determine the hypothesis that continuous adductor canal block (CACB) combined with the distal interspace between the popliteal artery and the posterior capsule of the knee (IPACK) block could effectively alleviate the pain of the posterior knee, decrease opioids consumption, and promote early recovery and discharge.

Methods: Patients undergoing unilateral, primary TKA were allocated into group CACB+SHAM (receiving CACB plus sham block) or group CACB+IPACK (receiving CACB plus IPACK block).

Effect of flurbiprofen axetil combined with "Cocktail" therapy on opioid dosage in patients after total knee arthroplasty.

Objectives: To investigate the effect of flurbiprofen axetil combined with "cocktail" therapy on opioid dosage in patients after total knee arthroplasty (TKA).

Methods: The clinical data of 200 patients who underwent TKA in Baoding No.1 Central Hospital hospital from March 2019 to March 2021 were collected for retrospective analysis.

Prazosin inhibits the growth and mobility of osteosarcoma cells.

Background: Osteosarcoma is a primary malignant bone tumor that frequently occurs in adolescents and children, its high aggressiveness and rapid metastasis often resulting in poor prognoses. In previous studies, Prazosin has been shown to possess anti-proliferative properties against prostate cancer and glioblastoma cells. In our study, we investigated Prazosin's underlying mechanisms and its effects on the biological behaviors of osteosarcoma cells.
