目的：通过影像学资料测量膝关节单髁关节置换术后内侧间室关节线改变情况，研究其与术后股胫角改变之间的关系，同时研究其与术后关节功能之间的关系，探讨关节线改变的意义。
方法：对2012年7月至2015年8月56例接受膝关节单髁置换术的患者进行回顾性研究。其中男21例，女35例；年龄50~82岁，平均62.3岁。BMI指数18.3~30.1，平均23.5。取前后位膝关节负重全长X线片，测量术后关节线改变值。分别测量术前术后股胫角，计算股胫角改变值。术后随访时使用膝关节HSS评分对膝关节功能进行评估。分析关节线改变与股胫角改变、术后膝关节功能的相互关系。
结果：胫骨内侧间室关节面抬高（2.2±2.0）mm（-3.3~7.0 mm），股胫角改变（2.3±3.0）°（-4.5°~9.6°），胫骨内侧关节面抬高值与股胫角改变值间有显著相关性（P<0.05）。术后随访12.2个月（10~16个月），关节面抬高值与术后HSS评分间无明显相关性（P>0.05）。
结论：膝关节单髁置换术后内侧间室关节线的改变与股胫角的改变呈显著相关性，术中胫骨侧截骨是同时关系这两者的关键因素，关节线的改变与术后短期临床功能之间无明显相关性，这可能与单髁关节的假体设计有关。 |

| Correlation of medial compartmental joint line elevation with femorotibial angle correction and clinical function after unicompartmental arthroplasty |
|
Abstract:
Objective: To study the correlation of postoperative femorotibial angle with medial compartmental joint line elevation after unicompartmental arthroplasty(UKA),as well as the correlation of joint line elevation with the clinical function by measuring radiological joint line.
Methods: A retrospective study of 56 patients from July 2012 to August 2015 was performed. The mean body mass index (BMI) was 23.5 (ranged,18.3 to 30.1). The standing anteroposterior radiographs of these patients were assessed both pre-and post-operatively,and the knee function was evaluated according to HSS grading. The correlation between postoperative femorotibial angle(FTA) and joint line elevation was analyzed as well as the correlation between joint line elevation and the clinical function.
Results: The mean medial joint line elevation was (2.2±2.0) mm(ranged,-3.3 to 7.0 mm),and the mean FTA correction was (2.3±3.0)°(ranged,-4.5° to 9.6°). The mean follow-up period was 12.2 months. There was a significant correlation between in joint line elevation and FTA correction(P<0.05),while there was no significant correlation between joint line elevation and the clinical function(P>0.05).
Conclusion: There was a significant correlation between medial compartmental joint line elevation and FTA correction after UKA,and the proximal tibial osteotomy was critical during the procedure. There was no significant correlation between joint line elevation and the clinical function,which may be related to the design of UKA prosthesis. |
