目的:确定术前软骨下骨髓水肿(SBME)的存在是否与外侧单室膝关节置换术(LUKA)后不良预后相关。
方法:描述性研究。研究的地点和持续时间:骨科,重庆中医骨科医院,重庆,中国,从2019年1月到2022年6月。
方法:接受LUKA治疗的患者数据来自医学注册数据库。两组均根据术前磁共振成像(MRI)是否存在SBME进行。视觉模拟量表(VAS)美国膝关节协会得分(AKSS)比较两组患者满意度。
结果:共20例接受LUKA治疗的患者。9例存在SBME,11例不存在。SBME患者在术前评估以及术后1、3和6个月的评分较差。然而,12个月随访时,两组间无显著差异.8例(88.9%)的SBME患者对LUKA手术满意,9例(81.8%)的SBME患者对LUKA手术满意,组间无显著差异。
结论:术前存在SBME与LUKA术后6个月内的不良功能结局相关。
背景:骨髓,水肿,膝盖,关节成形术,结果,患者满意度。
OBJECTIVE: To determine whether the presence of preoperative subchondral bone marrow oedema (SBME) is associated with inferior outcomes after lateral unicompartmental knee arthroplasty (LUKA).
METHODS: Descriptive study. Place and Duration of the Study: Department of Orthopaedic Surgery, Chongqing Orthopaedic Hospital of Traditional Chinese Medicine, Chongqing, China, from January 2019 to June 2022.
METHODS: Data on patients treated with LUKA were obtained from the Medical Registry Database. Two groups were made based on the presence and absence of SBME on preoperative magnetic resonance imaging (MRI). The visual analogue scale (VAS), American Knee Society Scores (AKSS), and rate of patient satisfaction were compared between the two groups.
RESULTS: A total of 20 patients treated with LUKA were reviewed. The SBME was present in 9 cases and absent in 11 cases. Patients with SBME had inferior scores at preoperative evaluation and at 1, 3, and 6 months postoperatively. However, there was no significant difference between the groups at the 12-month follow-up. Eight (88.9%) patients with SBME were satisfied with the LUKA surgery versus 9 (81.8%) patients without SBME, showing no significant differences between groups.
CONCLUSIONS: Presence of preoperative SBME is associated with inferior functional outcomes after LUKA within six months of follow-up.
