目的 观察运用两种不同缝线固定修补材料对疝修补术后的复发、切口感染、慢性疼痛等并发症发生情况。方法 对2008年4月至2010年4月期间笔者所在科室收治的250例腹股沟疝患者行无张力疝修补手术时，采用多股丝线或可吸收合成缝线固定修补材料进行前瞻性对比研究。结果 2组患者术后疝复发、切口感染和切口疼痛（包括慢性疼痛）发生率间的差异均无统计学意义（P＞0.05）。结论 腹股沟疝无张力修补术后的复发、切口感染、慢性疼痛等并发症的发生与缝线选择无关。术者的操作技巧、严格的无菌操作原则、彻底止血以及组织损伤小才是防止术后感染、慢性疼痛等并发症发生的重要因素。
Objective To investigate the effectiveness of double-needle suture for mixed meniscus tear repair under arthroscope. Methods Between April 2006 and January 2011, 22 patients with mixed meniscus tear were treated with double-needle suture under arthroscope. There were 14 males and 8 females, aged 18-41 years (mean, 31.3 years). All injuries were caused by sports. The time between injury and admission ranged from 2 days to 4 years (median, 11 months). International Knee Documentation Committee (IKDC) score was 42.5 ± 15.2, Lysholm score was 45.5 ± 13.5, and Tegner score was 2.9 ± 1.6. Seventeen cases complicated with anterior cruciate ligament injury. Results Healing of incision by first intention was achieved in all patients. No injury of nerve and blood occurred. The patients were followed up 12-48 months with an average of 27.6 months. According to Barrett et al. standard, 19 cases (86%) got clinical healing. The IKDC, Lysholm, and Tegner scores were improved to 77.1 ± 8.9, 79.8 ± 9.9, and 6.8 ± 1.6 respectively at last follow-up, showing significant differences when compared with preoperative scores (P lt; 0.05). Conclusion Arthroscopic meniscus repair using double-needle suture can provide good effectiveness because it has high firmness.
Objective To evaluate the surgical techniques and effectiveness of arthroscopic treatment of anterior cruciate ligament (ACL) tibial eminence avulsion fracture with non-absorbable suture fixation combined with the mini-plate. Methods Between January 2009 and March 2012, 32 patients with ACL tibial eminence avulsion fractures were treated. There were 18 males and 14 females, aged 12-40 years (mean, 17.5 years). The injury causes included traffic accident injury in 15 cases, sport injury in 6 cases, and falling injury in 11 cases. The time from injury to operation ranged 7-18 days with an average of 9.5 days. Before operation, the results of Lachman test were all positive; the Lysholm score was 52.13 ± 4.22 and the International Knee Documentation Committee (IKDC) score was 44.82 ± 2.44. According to Meyers-McKeever classification criteria, there were 12 cases of type II and 20 cases of type III. After arthroscopic poking reduction of fracture, tibial eminence avulsion fractures were fixed with the Ethibond non-absorbable sutures bypass figure-of-eight tibial tunnel combined with the metacarpal and phalangeal mini-plate. Results Primary healing was obtained in all incisions; no joint infection or skin necrosis occurred after operation. All patients were followed up with an average time of 22.4 months (range, 12-50 months). The patients showed negative Lachman test at 12 weeks after operation. Except 3 patients having knee extension limitation at last follow-up, the knee extension range of motion (ROM) was normal in the other patients; the knee flexion ROM was normal in all patients. The Lysholm score and IKDC score were significantly improved to 94.19 ± 0.93 and 94.35 ± 1.22 at last follow-up, showing significant differences when compared with preoperative values (t=55.080, P=0.000; t=101.715, P=0.000). Conclusion The arthroscopic treatment of ACL tibial eminence avulsion fracture with Ethibond non-absorbable suture fixation combined with mini-plate is an effective procedure with the advantages of minimal trauma, reliable fixation, and satisfactory recovery of the knee joint function.
Objective To explore the surgical method and effectiveness of multi-spot suture fixation under arthroscope in treating tibial intercondylar anterior eminence fracture. Methods Between February 2006 and January 2010, 15 patients with tibial intercondylar anterior eminence fracture were treated with multi-spot suture fixation under arthroscope after fracture reduction. There were 14 males and 1 female with a median age of 33 years (range, 7-55 years). The injury causeswere traffic accident in 9 cases, sport in 2 cases, and fall ing in 4 cases. The anterior drawer test, Lachman test, and pivot shift test in all the cases turned out to be positive. The Lysholm score was 64.7 ± 1.3. According to Meyers-McKeever classification, 5 cases were classified as type II, 7 cases as type III, and 3 cases as type IV. Of them, 13 cases had fresh fracture and 2 cases had old fracture. Assisted with anterior cruciate l igament-aimer, bone tunnels (2 mm in diameter) were built through the fracture fragments after fracture reduction, through which Ethibond 2 polyester sutures were guided into the joint by No.18 spine needles; after knot of 2 sutures or knot of only 1 suture was made, the other ends of sutures were fastened together outside the joint. Results The incisions of all the cases healed by first intention with no compl ication of infection or deep venous thrombosis. Fifteen patients were followed up 14-48 months with an average of 24.2 months. The X-ray examination indicated fractures healed in all the cases at 2-4 months (mean, 3 months). At 6 months after operation, 14 cases showed negative results of Lachman test and anterior drawer test but 1 case positive, while all the cases showed negative results in pivot shift test. The extension and flexion spheres of knee activity were normal in 13 cases and were l imited in 2 cases. The Lysholm score was 95.1 ± 2.1, showing significant difference when compared with the preoperative score (t=43.020, P=0.000). Conclusion Multi-spot suture fixation under arthroscope is an effective method with small invasion, rel iable fixation, and simple operation for treating tibial intercondylar anterior eminence fracture.
Objective To compare the effectiveness of arthroscopic screw and suture fixations in treatment of anterior cruciate ligament tibial eminence avulsion fractures. Methods Between January 2002 and January 2009, 43 patients with freshanterior cruciate ligament tibial eminence avulsion fracture were treated, which were rated as types II and III according to Meyers- McKeever-Zaricznyj classification. Fractures were fixed with either screw (screw group, n=21) or nonabsorbable suture (suture group, n=22). There was no significant difference in sex, age, disease duration, and fracture type between 2 groups (P gt; 0.05). The range of motion (ROM) and Lysholm score were compared between 2 groups, and the knee stabil ity was evaluated based on the Lachman test and KT-2000 measurement. Results The operation time was 48-60 minutes (mean, 51.6 minutes) in the screw group, and 55-68 minutes (mean, 63.2 minutes) in the suture group, showing significant difference (t=4.645, P=0.032). Incisions healed by first intention and no compl ication occurred in 2 groups. All patients were followed up (5.7 ± 0.6) years in the screw group and (5.3 ± 0.5) years in the suture group. The fracture healed completely in both groups; the heal ing time was (3.3 ± 0.6) months in the screw group and (3.2 ± 0.4) months in the suture group, showing significant difference (t=3.723, P=0.019). Between the screw group and the suture group, no significant difference was found in ROM [(128.6 ± 10.1)° vs. (130.2 ± 14.1)°, P gt; 0.05] and Lysholm score (94.6 ± 14.5 vs. 95.1 ± 17.2, P gt; 0.05). The stabil ities based on KT-2000 measurement were also similar between 2 groups at last follow-up [(0.9 ± 0.3) mm vs. (1.0 ± 0.4) mm, P gt; 0.05]. Lachman test of 2 groups were negative. Conclusion Boththe screw and nonabsorbable suture fixation techniques for anterior cruciate l igament tibial eminence avulsion fracture (type II or III) have good results in terms of functional outcome and stabil ity. However, some patients show flexion contractures of 5° or 10°.
Objective To introduce the arthroscopic technique of figure-of-eight suture fixation for tibial eminence fracture, and to report its clinical results. Methods From January 1998 to June 2001, 21 cases of tibial eminence fracture were treated arthroscopically with figure-of-eight suture fixation technique. Active rehabilitation began one week after operation. The patients were followed up 6-24 months. The reduction and union of fracture, knee laxity, range ofmotion, and total knee function were evaluated. Results All fracture healed without displacement six weeks after operation. Three months postoperatively, no knee laxity or instability was detected in all patients; full range of motion of the affected knee returned in all patients when compared with the normal side. Six months postoperatively, the Lysholm knee score was 93.4±2.7. Conclusion Arthroscopic treatment of tibial eminence fracture with figure-of-eight suture fixation technique is reliable for fracture reduction , fixation and early mobilization. Arthroscopy is conducive to diagnoses and treatment of associated knee arthropathy, reduces the morbidity associated with arthrotomy, and restores knee function to the greatest extent when combined with figure-of-eight suture fixationtechniques.
