摘要:
目的:探讨轻中度膝内外翻患者行全膝关节置换术(Total Knee Arthroplasty,TKA)时运用试模复位技术确定胫骨假体旋转定位区间及旋转对线的临床疗效。方法:选取2019年10月至2022年3月62例行初次单侧全膝关节置换术的患者,术中运用试模复位技术进行胫骨旋转定位,术后随访采用膝关节活动度、美国膝关节协会评分(KSS评分)评价临床效果,行CT扫描并测量胫骨假体旋转角度及假体旋转不匹配度。结果:胫骨假体相对于胫骨结节内侧缘处于外旋位,平均旋转角度α1=7.43°±3.18°; 胫骨假体相对于胫骨结节中、内侧缘1/3处于内旋位,平均旋转角度α2=-13.12°±4.38°; 股骨和胫骨假体旋转不匹配角度β角平均为2.42°±4.17°。随访时间为6～18 个月,平均为(12.31±2.15)个月,62例患者均未出现手术相关并发症,术后膝关节活动度为115.63°±6.98°,KSS临床评分为(90.02±2.92)分,功能评分为(83.22±6.41)分,与术前差异有统计学意义(P<0.05)。结论:轻中度膝内外翻患者行全膝关节置换手术时运用试模复位技术确定胫骨假体的旋转定位可以获得良好的临床效果,其定位区间位于胫骨结节内侧缘与胫骨结节中、内侧缘1/3之间。
Abstract:
Objective:To explore the clinical efficacy and range of tibial rotational alignment using the range of motion(ROM)technique for determining the rotational alignment of the tibial prosthesis in cases of mild to moderate varus and valgus deformity in total knee arthroplasty(TKA).Methods:A retrospective study was conducted on 62 patients who underwent TKA between October 2019 and March 2022.The tibial component was positioned using the ROM technique.The rotational alignment of the tibial component was measured on CT images with reference to the medial aspect of the tibial tubercle and the medial one-third of the tibial tubercle.The range of motion and knee society score(KSS)were used to assess the clinical outcomes.Results:The rotational alignment of the tibial component was found to be 7.43°±3.18° relative to the medial aspect of the tibial tubercle and -13.12°±4.38° relative to the medial one-third of the tibial tubercle.There was a significant difference between the two groups(P<0.05).The rotational mismatch was measured to be 2.42°±4.17°.The follow-up period ranged from 6 to 18 months,with an average of(12.31±2.15)months.No postoperative complications were observed.The ROM was recorded as 115.63°±6.98°.The clinical postoperative KSS scores were(90.02±2.92)points,and the functional KSS scores were(83.22±6.41)points.Conclusion:The use of the ROM technique for positioning the tibial rotational alignment in cases of mild to moderate varus and valgus deformity in TKA has shown promising clinical efficacy.The ideal range of tibial rotational alignment in TKA was found to be from the medial border of the tibial tubercle to the medial one-third of the tibial tubercle.Employing the ROM technique for tibial rotational alignment facilitates a more suitable matching of the tibial component with the femoral component and provides reliable tibiofemoral joint dynamics characteristics.
