Objective To summarize the clinical features of chronic ruptured patellar tendon, and introduce the augmentation technique of repair of chronic ruptured patellar tendon with high strength polyester sutures and postoperative rehabilitation.Methods Six cases of chronic patellar tendon rupture were treated and reinforced with high strength polyester sutures from 2002 to 2007.Patellar tendon ruptures was primary end Ho -end repaired, and reinforced with 4 polyester sutures that were passed through in-traosseous tunnels within the patella and tibial tubercle.The surgery reestablished knee extensor continuity and restored the length of patellar tendon.Augmentation techniques were reliable, and allowed patients to walk and bend the knee, regain adequate quadriceps strength early.Postoperative rehabilitation: on the 1st day after surgery, walking upright and passive flexion of 90° was allowed, and brace protection was unnecessary; 3 weeks later, straight leg raise; 6 weeks later, brisk walking; 12 weeks later, squatting and climbing stairs; 6 months later, sports was allowed, including the jump and kick.Results All patients were followed up from 1 to 5 years.No patient sustained a re-rupture.All patients satisfied with their result.The Lysholm score were 100.Kach knee had restored full range of motion 6 months later, and regained adequate quadriceps strength.Conclusion Augmentation techniques with high strength polyester sutures is reliable and demonstrate good intermediate to long-term results.It can avoid re-operation for removal of the cerclage wire, allow patients to walk and bend the knee, regain adequate quadriceps strength early.

Objective To study the difference of transverse incision and longitudinal incision for B-T-B graft harvesting in reconstruction of anterior cruciate ligament.Methods Sixty four cases of reconstruction of anterior cruciate ligament from January 2004 to December 2004 were observed.Transverse incisions were used in 32 cases,and longitudinal incision were chosen in the other 32.The operation time,the length of incision,the thickness of scar,the injury of saphenous nerve and the joint function of knee were compared.Results All patients were followed up more than 1 year.The average duration of surgical procedure with longitudinal incision was 11 minutes shorter than that with transverse incision.The scar of transverse incision is smaller and thinner than that of longitudinal incision.The injury of saphenous nerve and knee joint function of knee revealed no notable difference in the 2 groups.Conclusions Transverse incision for B-T-B graft harvesting in reconstruction of anterior cruciate ligament is a better choice.

Objective To introduce Torg's modified Bristow procedure for recurrent anterior dislocation of the shoulder joint,and to evaluate it's clinical result.Methods 25 shoulders with recurrent anterior dislocation were treated with Torg's modified Bristow procedure from January 2002 to December 2006.Based on history,physical examination and X-ray examination,all the diagnosis were confirmed.The follow-up period ranged from 1 to 5 years,with an average of 3.1 years.Results All the cases had Hillsachs lesions and Bankart lesions.After 2 years,only one shoulder had redislocated and 96% of patients were satisfied with the operative repair.The Rowe standard rating scale:excellent 72%;good 24%;fair 4%;poor 0%.Conclusion Torg's modified Bristow procedure provided a good functional result in patients with recurrent shoulder dislocations.

Objective To compare the clinical outcomes of anterior cruciate ligament(ACL)reconstruction by using allograft and autograft of patella tendon.Methods From August 2003 to December 2005,82 ACL reconstruction patients were studied retrospectively,including 59 cases using autograft of patellar bone-tendon-bone(BPTB)and 23 cases using BPTB allograft.Physical examination,scores of IKDC,Lysholm-Tegner and VAS as well as KT-2000 measurements were used for evaluation pre-and post-operation.Results 41 autograft and 17 allograft patients were finally followed up.One allograft patient suffered re-rupture of the reconstructed ligament.Positive ADT test were found in 5 autograft and 1 allograft patients and positive Lachman test were found in 3 autograft and 1 allograft patients.No statistically significant differences were revealed in ROM.IKDC,Lysholm-Tegner Score and KT-2000 measurements showed no significant differences between two groups,but VAS for autograft group were significantly higher than allograft group(P

Objective To study the diagnostic value of porphobilin staining of gastric mucus for primary pathologic duodenogastric reflux (DGR). Methods A total of 58 DGR patients diagnosed from January, 2007 to April, 2008 were recruited to the study as DGR group, and 21 healthy volunteers as control.All subjects underwent 24-hour intragastric bilirubin monitor and gastroscopy. Bilirubin absorption value of 0. 25 and median reflux time of 23.60% were taken as thresholds to differentiate low reflux group ( reflux time ＜ 23.60% ) and high reflux group (reflux time ≥23.60% ). Porphobilin staining of gastric mucosa was quantitatively analyzed. Results Deposition of porphobilin in mucosa of gastric antrum, gastric angle and gastric body in primary pathologi DGR group was significantly higher than those in healthy group (P ＜0. 05 ). The occurrence of atrophic and intestinal metaplasia of gastric antrum in high reflux group was significantly higher than that of low reflux group (P ＜ 0. 05). Deposition of porphobilin in mucosa of gastric antrum, gastric angle and gastric body in high reflux group was significantly higher than that of low reflux group (P ＜ 0. 05 ). The New Sydney system pathological scores of gastric antrum and angle of high reflux group was higher than that of low reflux group ( P ＜ 0. 05 ). The deposition of porphobilin in mucosa of gastric antrum and gastric angle was positively correlated with New Sydney system pathological scores in primary pathological DGR group (r=0.59, P=0.041 andr=0.73, P=0.038). Conclusion Porphobilin staining of mucosa in gastric antrum can reflect the severity of bile reflux, and is positively correlated with the extent of gastric mucosal lesion, which may be helpful in diagnosis of primary pathological DGR.
