ABSTRACT
BACKGROUND:Traditional total knee arthroplasty adopts medial parapatel ar approach, which induces severe trauma, requires long-term rehabilitation, and interferes the end point of quadriceps femoral tendon on superior patel ar pole. Total knee arthroplasty by subvastus approach has no impact on the knee-extension equipment, but it cannot provide sufficient exposure of surgical field and can induce damage to femoral muscle, so its application and safety need further exploration. OBJECTIVE:To explore clinical effect of total knee arthroplasty by subvastus approach and medial parapatel ar approach. METHODS:A total of 78 patients with 82 knees who were candidates for total knee arthroplasty were randomly divided into two groups. Treatment group (39 cases;41 knees) was given subvastus approach and control group (39 cases;41 knees) was given median parapatel ar approach. The knee function, range-of-motion of knee joint and complications after total knee arthroplasty were observed and compared. RESULTS AND CONCLUSION:Compared with control group, the operation time in treatment group was significantly increased, while the postoperative wound drainage, straight leg raising time and walking time were obviously reduced (P0.05), while at 1 and 6 weeks after surgery the scores in treatment group were significantly higher than those in control group (P<0.05). The range-of-motion of knee joint and MMT rank for quadriceps muscle were significantly improved in two groups after treatment (P<0.05), and those indicators in treatment group were more significant than the control group (P<0.05). The incidences of complications in treatment group and control group were 2.6%and 15.4%, respectively, with statistical y significant difference (P<0.05). The total knee arthroplasty by subvastus approach has less impact on the extensor mechanism, improves the recovery of knee function and range-of-motion of knee joint, and reduces the incidence of complications.

ABSTRACT
Objective To study the dynamic change of high-sensitivity C-reactive protein(hCRP),interleukin-1(IL-1?)interleukin-6(IL-6)in acute traumatic brain injury,and the correlation between the dynamic change and the scale of brain injury and the prognosis of the patients.Methods 192 cases patients were divided into different groups according to the Glasgow Coma Scale(GCS)and the Glasgow outcome Scale(GOS)three months later discharged from hospital respectively.The concentration of serum CRP,IL-1?,IL-6 were detected with immunoturbidimetry and ABC-ELISA 24 with in hours after traumatic brain injury and the concentration of serum after iniwn at ond day,three days and seven days was detected as well.Results Serum hCRP levels were remarkably elevated and reached peak value within 24 hours,and then gradually decreased.There were a negative correlation between hCRP,IL-1?,IL-6 and the patient's GCS groups(r=-0.162,P
