关节镜下单通道双线技术治疗胫骨髁间棘骨折

目的:探讨关节镜下单通道双线技术治疗胫骨髁间棘骨折的临床疗效。方法:2016年1月至2020年4月,收治22例胫骨髁间棘骨折患者,男14例,女8例;年龄26~45(34.8±5.9)岁;手术时间为受伤后5~15(11.2±4.1) d。所有患者给予关节镜下骨块复位和单通道双线技术固定。术后根据X线片评估骨折愈合情况,术前及末次随访采用Lysholm评分、IKDC 2000评分和抽屉试验进行临床疗效评价。结果:22例患者全部获得随访,时间12~75(34.6±13.0)个月。Lysholm评分术前(30.80±9.55)分,末次随访(89.60±2.89)分,差异有统计学意义(t=9.67,P<0.01);IKDC 2000术前(24.60±7.21)分,末次随访(80.00±6.17)分,差异有统计学意义(t=11.41,P<0.01)。1例患者抽屉试验为弱阳性。结论:单通道双线技术可实现对髁间棘撕脱骨块的有效固定,操作简便、创伤小,适用于各种类型的髁间棘撕脱骨折。目的:探讨关节镜下单通道双线技术治疗胫骨髁间棘骨折的临床疗效。方法:2016年1月至2020年4月,收治22例胫骨髁间棘骨折患者,男14例,女8例;年龄26~45(34.8±5.9)岁;手术时间为受伤后5~15(11.2±4.1) d。所有患者给予关节镜下骨块复位和单通道双线技术固定。术后根据X线片评估骨折愈合情况,术前及末次随访采用Lysholm评分、IKDC 2000评分和抽屉试验进行临床疗效评价。结果:22例患者全部获得随访,时间12~75(34.6±13.0)个月。Lysholm评分术前(30.80±9.55)分,末次随访(89.60±2.89)分,差异有统计学意义(t=9.67,P<0.01);IKDC 2000术前(24.60±7.21)分,末次随访(80.00±6.17)分,差异有统计学意义(t=11.41,P<0.01)。1例患者抽屉试验为弱阳性。结论:单通道双线技术可实现对髁间棘撕脱骨块的有效固定,操作简便、创伤小,适用于各种类型的髁间棘撕脱骨折。

Clinical outcomes of arthroscopic single-tunnel double-line technique in treating tibial intercondylar eminence fractures

Objective: To evaluate clinical efficacy of single-tunnel double-line technique with tendoscopy in treating tibial intercondylar eminence fractures.Methods: From January 2016 to April 2020,22 patients with tibial intercondylar eminence fractures were admitted,including 14 males and 8 females with a mean age of (34.8±5.9) years old ranging from 26 to 45 years old. The mean duration from injury to surgery was(11.2±4.1) days(ranged,5 to15 d). All patients were treated with arthroscopic single-tunnel double-line technique. The fracture healing was evaluated according to X-ray. The Lysholm score,IKDC 2000 score and the anterior drawer test were used to evaluate efficacy before operation and at the latest follow-up.Results: All patients were followed up,and the duration ranged from 12 to 75 months,with an average of(34.6±13.0) months. Lysholm score was (89.60±2.89) points at the latest follow-up,showing significant difference when compared with preoperative score which was (30.80±9.55)points(t=9.67,P<0.01). IKDC 2000 score was(80.00±6.17) points at the latest follow-up,showing significant difference when compared with preoperative score which was (24.60±7.21)points(t=11.41,P<0.01). One patient showed weakly positive of drauer test.Conclusion: Single-channel double-line technique could effectively fix bone block of intercondylar eminence with advantage of easy operation and minimally invasive,which could be applied to various types of tibial intercondylar eminence fractures.
