EDEMA, WOUND INFECTION, SKIN, VENOUS THROMBOSIS
No limb swelling occurred in the ACB + GA group after surgery and vascular ultrasound examination showed no venous thrombus of the lower limbs 24 h postoperatively. In the SGA group, 24 h after the operation, four cases experienced crus swelling of different degrees. The patients were instructed to elevate the affected limbs and performed ankle pump exercises to reduce edema. One case of tension vesicle was observed. Skin vesicle was punctured and healed after wound dressing. Two cases of intermuscular venous thrombus were observed on ultrasound examination. Low molecular weight heparin (Sanofi, France) were injected (0.4 ml, q 12 h), and venous thrombosis were confirmed to disappear by ultrasound reexamination before discharge. Neither group had wound infection. Only one patient in the ACB + GA group had fat liquefaction and the wound healed after a fresh dressing change. One patient in the SGA group suffered from knee stiffness. Knee ROM returned to normal under manipulation under anesthesia (MUA) at 6 weeks postoperatively.
