目的：探讨不同程度膝内翻畸形患者行初次全膝关节置换术后下肢力线分布与近期临床疗效之间的关系。
方法：自2016年12月至2018年3月行初次全膝关节置换术治疗的膝骨性关节炎患者87例（101膝），男21例（25膝），女66例（76膝）；年龄51～85（67.6±7.0）岁。根据患者全膝关节置换术后下肢髋膝踝角（hip-knee-ankle angle，HKA）不同分为4组：中立位组（A组），-3°≤HKA≤3°，50膝；轻度内翻组（B组），3° < HKA < 6°，20膝；严重内翻组（C组），HKA≥6°，20膝；外翻组（D组），HKA<-3°，11膝。比较4组患者术前性别、年龄、体质量指数、手术侧别、术前及术后膝关节活动度，美国特种外科医院膝关节评分（Hospital for Special Surgery Knee Score，HSS），美国膝关节协会评分（Knee Social Score，KSS），并分别比较术后股骨、胫骨假体力线分布与近期临床疗效的关系。
结果：所有病例获得随访，时间（18.4±4.0）个月。4组患者术后末次随访膝关节活动度、HSS、KSS评分均较术前提高（P<0.001）。4组患者术后末次随访HSS、KSS评分组间比较差异具有统计学意义（P<0.05）；A组评分优于C、D两组（P<0.05），B组评分优于C、D两组（P<0.05），A、B两组间以及C、D两组间比较差异无统计学意义（P>0.05）；4组患者术后膝关节活动度组间比较差异无统计学意义。股骨假体力线在±3°以内组评分优于3°以外组（P<0.05），胫骨假体力线在±3°以内组评分较3°以外组差异无统计学意义（P>0.05）。
结论：膝内翻型骨关节炎患者初次全膝关节置换术后近期临床疗效与下肢力线分布有关，力线轻度内翻位分布可获得与中立位相似的近期临床疗效，股骨假体力线分布与初次膝关节置换术后近期临床疗效有关。 |

| Relationship between lower limb alignment distribution and short-term clinical results after primary total knee arthroplasty in patients with varying degrees of knee varus |

Abstract:
Objective: To analyze the relationship between the distribution of lower limb alignment and short-term clinical efficacy in patients with varus-type osteoarthritis after primary total knee arthroplasty (TKA).
Methods: From December 2016 to March 2018,87 patients(101 knees) with knee osteoarthritis were treated with the first total knee arthroplasty by the same medical group,including 21 males(25 knees) and 66 females(76 knees),ranging in age from 51 to 85 years old,with a mean of (67.6±7.0) years old. According to the difference of hip knee ankle angle (HKA) after total knee arthroplasty,the patients were divided into 4 groups:neutral position group (group A),-3° ≤ HKA ≤ 3°,50 knees;slight varus group (group B),3° < HKA < 6°,20 knees;severe varus group (group C),HKA ≥ 6°,20 knees;valgus group (group D),HKA < -3°,11 knees. The preoperative sex,age,body mass index,operative side,preoperative and postoperative knee joint activity,HSS score,KSS clinical and functional score were compared among the 4 groups,and the relationship between the force line distribution of femoral and tibial prosthesis and the recent clinical effect was compared.
Results: All the patients were followed up with a mean duration of(18.4±4.0) months. The range of motion of knee joint,HSS and KSS scores at the latest follow-up after operation in the 4 groups were higher than those before operation,and the difference was statistically significant (P<0.001). There were significant differences in HSS and KSS scores among the 4 groups at the latest follow-up (P<0.05);and the results in group A were better than those in group C and group D(P<0.05);the results in group B were better than those in group C and group D(P<0.05);there was no significant difference between group A and group B or group C and group D(P>0.05). There was no significant difference in knee joint activity among the 4 groups. The score of femoral prosthesis force line within ±3°was better than that of the other group(P<0.05),and the score of tibia prosthesis force line had no significant difference between within ±3°group and other group(P>0.05).
Conclusion: The short-term clinical efficacy of patients with knee varus osteoarthritis after primary total knee arthroplasty is related to the distribution of lower limbs alignment. The short-term clinical efficacy of slight inversion position can be similar to that of neutral position. The force line distribution of femoral prosthesis is related to the short-term clinical efficacy after primary knee arthroplasty. |
