  • 锚钉技术重建膝关节内侧副韧带

    目的 总结采用锚钉技术重建膝关节内侧副韧带的临床疗效。 方法 2007 年2 月- 2009 年3 月,采用小切口骨锚钉固定重建21 例断裂的膝内侧副韧带。男12 例,女9 例;年龄17 ~ 61 岁,中位年龄30 岁。致伤原因:车祸伤18 例,扭伤2 例,运动伤1 例。左膝8 例,右膝13 例。均为Ⅱ~Ⅲ度断裂患者,其中股骨内髁附着点断裂12 例,胫骨内髁附着点断裂9 例。除1 例伤后1 个月手术外,其余患者受伤至手术时间为2 ~ 7 d。 结果 术后切口均Ⅰ期愈合。19 例获随访,随访时间13 ~ 25 个月,平均16.5 个月。术后12 个月膝关节功能Lysholm评分为(94.2 ± 5.7)分,与术前(26.3 ± 8.3)分比较差异有统计学意义(P lt; 0.01);其中优13 例,良4 例,可2 例。术后Lysholm 评分各指标均高于术前,差异均有统计学意义(P lt; 0.01)。 结论 锚钉技术具有手术操作简便、创伤小、固定可靠、并发症少等优点,是重建膝内侧副韧带的有效方法之一。

  • APPLICATION OF TIBIAL MECHANICAL AXIS LOCATOR IN TIBIAL EXTRA-ARTICULAR DEFORMITY IN TOTAL KNEE ARTHROPLASTY

    Objective To explore the application value of self-made tibial mechanical axis locator in tibial extra-articular deformity in total knee arthroplasty (TKA) for improving the lower extremity force line. Methods Between January and August 2012, 13 cases (21 knees) of osteoarthritis with tibial extra-articular deformity were treated, including 5 males (8 knees) and 8 females (13 knees) with an average age of 66.5 years (range, 58-78 years). The disease duration was 2-5 years (mean, 3.5 years). The knee society score (KSS) was 45.5 ± 15.5. Extra-articular deformities included 1 case of knee valgus (2 knees) and 12 cases of knee varus (19 knees). Preoperative full-length X-ray films of lower extremities showed 10-21° valgus or varus deformity of tibial extra joint. Self-made tibial mechanical axis locator was used to determine and mark coronal tibial mechanical axis under X-ray before TKA, and then osteotomy was performed with extramedullary positioning device according to the mechanical axis marker. Results All incisions healed by first intention, without related complications of infection and joint instability. All patients were followed up 5-12 months (mean, 8.3 months). The X-ray examination showed lt; 2° knee deviation angle in the others except 1 case of 2.9° knee deviation angle at 3 days after operation, and the accurate rate was 95.2%. No loosening or instability of prosthesis occurred during follow-up. KSS score was 85.5 ± 15.0 at last follow-up, showing significant difference when compared with preoperative score (t=12.82, P=0.00). Conclusion The seft-made tibial mechanical axis locator can improve the accurate rate of the lower extremity force line in TKA for tibia extra-articular deformity.
