Objective To discuss the relationship between antibiotic prophylaxis and surgical site infection(SSI) in colorectal cancer.Methods A survey of 880 patients with colorectal cancer from Jan.1998 to Dec.2008 were studied.Patients were divided into two groups by antibiotic duration: ≥24 h group(n=401) and 0.05).Conclusion Longer operation time,more blood loss and longer bleeding time are the risk factors of surgical site infection.Moreover prolonged antibiotic prophylaxis can not decrease the incidence of SSI.

Objective To investigate the influence and clinical significance of knee lateral thrust gait to femorotibial angle and lateral joint space in the patients with knee varus deformity. Methods 44 patients (male 10, female 34; range 31-60 years old, mean 41 years old) with knee varus deformity and lateral thrust involved in this study. The femorotibial angle and lateral joint space were measured on the standing anteroposterior film (single-foot loading and double-feet loading) of knee in order to compare the changes of them. The double-feet loading film simulated the corresponding relationship between thighbone and tibiae at double-support time, as early knee lateral thrust. The single-foot loading film simulated the corresponding relationship between thighbone and tibiae at single-support time, as late knee lateral thrust. The changes of femorotibial angle and lateral joint space in the two positions showed the changes of corresponding relation between thighbone and tibiae during knee lateral thrust. Results The mean femorotibial angle was 188.50??4.48? and 185.50??4.46? at the time of single-foot loading and double-feet loading respectively. It indicated that the femorotibial angle was increasing at the time of single-foot loading. The mean width of lateral joint space was (9.92?0.86) mm and (7.70?0.78) mm at the time of single-foot loading and double-feet loading respectively. It demonstrated that lateral joint space was widening more at the time of single-foot loading. The result suggested the lateral thrust of knee led to these changes. The increasing of femorotibial angle meant an increase of knee adduction moment during gait. The increasing of lateral joint space led to lateral structures chronic instability. The increased knee adduction moment and lateral structures chronic instability were the important mechanisms for degeneration of knee medial department. Conclusion The knee lateral thrust gait results in the augments of femorotibial angle and lateral joint space. These lead to the increase of the load on knee medial compartment, lateral structures chronic instability and varus deformity increasing. Lateral thrust might cause aggravation of knee varus and gonarthrosis at knee medial compartment.

[Objective]To analyze the reasons of complications in high tibial valgus osteotomy in the varus osteoarthritic knee and its management.[Method]We studied the results of valgus-producing high tibial osteotomies in patients who had medial unicompartmental osteoarthritis and varus malalignment.We performed the operation for 126 patients from January 2000 to October 2004.Twenty-one patients had complications,including four men and seventeen women,with average age of 61 years(ranged:48～64 years).The femorotibial angle was measured on the standing anteroposterior film of knee preoperatively in order to get high accuracy in preoperative planning.A lateral closing-wedge osteotomy was performed,the osteotomy site was stabilized by Giebel blade plate or stepped staple.[Result]The mean duration of follow-up was 7.5 months(ranged,6 to 12 months).There were twenty-three complications(21 patients,16.7%):tibial fracture in four cases,deep-vein thrombosis in five cases,peroneal nerve palsy in three cases,recurrence of varus deformity in six cases,internal fixation failure in four cases(recurrence of varus deformity developed in two patients),a superficial wound infection developed in one patient.[Conclusion]To reduce the incidence of complications in high tibial valgus osteotomy,we should make familiarication with anantomy and take more accuracy in preoperative planning,improve surgical skill as well as appropriate perioperative management.

Objective To evaluation high tibial osteotomy combined with anteromedial transfer of the distal fragment for the treatment of medial and patellofemoral compartmental osteoarthritis of the varus knee. Methods High tibial osteotomy was performed in 30 knees of 24 patients with medial and patellofemoral compartmental osteoarthritis of the varus knee, which was combined with anteromedial transfer of the distal fragment. The patients included 5 males (7 knees), 19 females (23 knees), with the mean age 53 years (range, 49-55 years). All patients were followed-up with footprints to assess the foot progression angle preoperatively and at 6 months to 2 years after the osteotomy. Tibial torsion of these subjects was measured by computerized tomography preoperatively and after the osteotomy. The statistical evaluation was carried out by the paired t test. Results The foot progression angle was 8.95??2.99? preoperatively, and -2.23??4.11? postoperatively during walking. The tibial torsion was 33.77??8.12? preoperatively and 21.27??8.48? after the osteotomy. The statistical evaluation showed foot progression angle and tibial torsion preoperative were significant difference from those postoperative (P 0.05). This result revealed that the decrease of foot progression angle was equal with the decrease of tibial torsion postoperatively. Conclusion High tibial osteotomy combined with anteromedial transfer of the distal fragment may be the effective method for medial and patellofemoral compartmental osteoarthritis of the knee, but it would cause calf and foot internal rotation. The change of foot progression angle and tibial torsion can influence the effect of high tibial osteotomy. The magnitude of anteromedial transfer of the tibial tubercle must be individualized and be devised preoperatively. It is important to evaluate patellofemoral malalignment and to measure the magnitude of tibial internal rotation in operation.

5 cm. Track record of average range of motion and KSS score. Results A total of 27 knees(10.23%) showed HO after TKA, which included type Ⅰ13 knees, typeⅡ8 knees, typeⅢ 6 knees. Average KSS score of typeⅢ was 83.1?1.5. It was lower than normal group(P0.05). Conclusion TypeⅢ HO after TKA impact clinic outcome. Ostephte increases the probability of HO, and NSAIDS decrease the probability. The incidence of HO have no relation with implants.

Objective To evaluate the clinical results from the treatment of local chondral or osteochondral lesions on the talus dome with autologous osteochondral transplantation or mosaicplasty harvested from the ipsilateral knee. Methods There were 23 patients with chondral defects of the talus dome including post-traumatic cartilage defects(n=11), osteochondritis dissecans(n=9), and local osteoarthritis(n=3). The position and size of the defect were defined under ankle arthroscopy. The procedures consisted of debriding its edges and base drilled under ankle arthroscopy or arthrotomy, then harvesting osteochondral cylinders from non-weight bearing surface of the ipsilateral knee under arthroscopy, and using the osteochondral autograft transfer system(OATS) to implant the donor graft into the recipient holes of talus cartilaginous defects with press-fit technique. A single donor transplantation or the mosaicplasty was used. Results All the patients were followed up for 15 to 30 months(mean, 22 months). The mean pain intensity measured by standard visual analogue scale(VAS) reduced from 4.9?1.2 to 0.8?0.1 at final follow-up(P

[Objective]To evaluate efficacy and method of arthroscopic meniscoplasty for horizontal tear of discoid lateral meniscus in a short follow-up term. [Method]A series of 27 patients (27 knees) (mean age 32 years, range 6 years to 42 years) who underwent arthroscopic evaluation and treatment of a discoid lateral meniscus between 2002 and 2006 was reviewed. All the patients who were selected had the horizontal type of tear. Of those discoid menisci classified intraoperatively (n=27), 85.2% (n=23) were complete discoid lateral menisci and 14.2% (n=4) were incomplete discoid lateral menisci. No Wrisberg type was noted. Arthroscopic meniscoplasty was performed in all cases. The horizontal tear meant meniscus was divided into two leaves. The auther removed the unstable leaf to the peripheral rim and preserved the stable one. Arthroscopic meniscoplasty was performed in the stable leaf.[Result]All the patients were evaluated at follow-up according to the Lysholm knee Scoring Scale. At follow-up, patients were reviewed to recognize possible of retear and requirement of arthroscopic revision. The knee score of these patients improved from 72.48?4.64 points preoperatively to 92.18?4.52 points postoperatively. Recurrence of tear or requirement of arthroscopic revision was not noted at the final follow-up. [Conclusion]Arthroscopic meniscoplasty of the horizontal tear of discoid meniscus is an effective method.

0.05). But when the flexion exceeded 30?, especially when it exceeded 60?, the displacement in pPc increased markedly, much greater than that of an intact knee (P0.05), while a slight over-restriction may be found at some angles. Conclusion Double-band reconstruction could effectively restrict the posterior displacement of the tibia and restore anteroposterior stability to the knee joint within its full range of flexion. aPc reconstruction could also maintain the posterior stability of the knee, while the result of pPc reconstruction is most unsatisfactory.
