摘要

背景:在进行全膝关节置换术(TKA)时,外翻膝关节畸形矫正过程中,为寻求屈伸间隙的适当平衡,外侧上髁截骨是一种手术选择。然而,它的使用并不频繁,文献中描述的报道很少。本研究的目的是描述连续一组外翻畸形患者在TKA期间行外侧上髁截骨术的临床结果。方法回顾性分析2016年1月至2018年12月在TKA中行外侧上髁截骨术的18例外翻畸形患者。采用Ranawat分类对外翻畸形类型进行评估。在TKA前后用全景腿部站立x线片测量股骨胫骨角;用膝关节社会评分- kss和牛津膝关节评分量表评估功能。结果患者平均年龄71.8±6.1岁,女性13例。根据Ranawat的分类,11个膝关节有III级(>20°)外翻畸形。术前和术后平均股胫角分别为25.8°±9.9°和7.1°±1.8°。通过KSS和Oxford量表观察功能改善,与术前相比平均提高37.4±13.4分和32.4±6.7分。没有发现术中或术后并发症的证据。结论在这些患者中,外上髁截骨术被证明是一种有效的手术选择,可以在TKA中矫正外翻畸形,使肢体正确对准,并获得良好的功能效果。

Lateral epicondyle osteotomy for correction of valgus deformity during total knee arthroplasty: Surgical technique and clinical outcomes

Background

Lateral epicondyle osteotomy is one of the surgical choices when seeking a proper equalization and balance of the flexion and extension gaps during the correction of a valgus knee deformity, when performing a total knee arthroplasty (TKA). However, its use is not frequent, and the reports described in literature are scarce. The aim of this study was to describe the clinical outcomes of the patients in which lateral epicondyle osteotomy was performed during TKA in a consecutive group of patients with valgus deformity.

Methods

Retrospective study of 18 patients with valgus deformity, who had lateral epicondyle osteotomy during TKA, from January 2016 to December 2018. The type of valgus deformity was assessed with Ranawat’s classification. The femorotibial angle was measured with a panoramic leg standing X-rays before and after the TKA; The function was evaluated with the Knee Society Score-KSS and Oxford Knee Score scale.

Results

The average age was 71.8 ± 6.1 years and 13 cases were women. According to Ranawat’s classification, 11 knees had Grade III (>20°) valgus deformity. The mean preoperative and postoperative femorotibial angles were 25.8° ± 9.9° and 7.1° ± 1.8°, respectively. Functional improvement was observed through the KSS and Oxford scales, with an average increase of 37.4 ± 13.4 and 32.4 ± 6.7 points compared to preoperative. No evidence of intraoperative or postoperative complications associated with the procedure was found.

Conclusion

In these patients, the osteotomy of the lateral epicondyle proved to be an effective surgical option for the correction of valgus deformity during TKA, allowing proper alignment of the limb with good functional results.

期刊介绍: Journal of Arthroscopy and Joint Surgery (JAJS) is committed to bring forth scientific manuscripts in the form of original research articles, current concept reviews, meta-analyses, case reports and letters to the editor. The focus of the Journal is to present wide-ranging, multi-disciplinary perspectives on the problems of the joints that are amenable with Arthroscopy and Arthroplasty. Though Arthroscopy and Arthroplasty entail surgical procedures, the Journal shall not restrict itself to these purely surgical procedures and will also encompass pharmacological, rehabilitative and physical measures that can prevent or postpone the execution of a surgical procedure. The Journal will also publish scientific research related to tissues other than joints that would ultimately have an effect on the joint function.
