摘要
目的:评估半月板集中联合拔出修复和开放楔形胫骨高位截骨术(OWHTO)治疗内侧半月板后根撕裂(MMPRT)和内翻对准患者的放射学、临床和关节镜结果。方法:我们回顾性分析了2017年至2022年期间接受OWHTO手术的患者,包括MMPRT和内翻对准并接受半月板集中和经胫骨拔出修复的患者,随访时间至少为2年。评估临床和影像学结果,包括Rosenberg视图中的内侧关节间隙宽度(mJSW)。在钢板取出时(手术后1年)进行二次关节镜检查,评估半月板愈合和软骨状态。内侧半月板挤压(MME)在初次手术和二次关节镜检查中被分类。计算队列特异性最小临床重要差异(MCID)。结果:48例符合条件的患者中,37例可随访,纳入分析,平均随访时间为45.7±12.0个月(范围:24-71个月)。屈曲角度及各项临床评分均有明显改善。根据国际膝关节文献委员会(IKDC)的数据,92.9%的患者达到了MCID,在所有膝关节损伤和骨关节炎结局评分(kos)亚量表中,除kos运动外,80%的患者达到了MCID。mJSW由术前的2.7±1.0 mm增加到术后2年的2.9±1.0 mm (p = 0.046)。半月板完全愈合率为80.6%,国际软骨修复学会股骨内侧髁和胫骨内侧平台评分显著提高(p = 0.011, p = 0.006)。83.3%的患者MME得到改善。结论:在短期随访中,联合拔出修复、半月板集中和OWHTO显著改善了临床、放射学和关节镜预后,在Lysholm评分、IKDC主观评分和kos亚量表中达到MCID阈值的患者比例很高。
Combined medial meniscus repair, centralization, and high tibial osteotomy are associated with improved clinical, radiological, and arthroscopic outcomes in patients with posterior root tears and varus alignment.
Purpose: To evaluate the radiological, clinical, and arthroscopic outcomes following meniscal centralization combined with pull-out repair and open-wedge high tibial osteotomy (OWHTO) in patients with medial meniscal posterior root tear (MMPRT) and varus alignment.
Methods: We retrospectively analyzed patients who underwent OWHTO between 2017 and 2022, including those with MMPRT and varus alignment who received meniscal centralization and transtibial pull-out repair, with a minimum 2-year follow-up. Clinical and radiographic outcomes, including medial joint space width (mJSW) in the Rosenberg view, were evaluated. Second-look arthroscopy, performed at the time of plate removal (1 year after surgery), evaluated meniscal healing and cartilage status. Medial meniscus extrusion (MME) was classified at the initial surgery and second-look arthroscopy. The cohort-specific minimal clinically important difference (MCID) was calculated.
Results: Of the 48 eligible patients, 37 were available for follow-up and were included in the analysis, with a mean follow-up of 45.7 ± 12.0 months (range: 24-71 months). The flexion angle and all clinical scores were significantly improved. MCID was achieved in 92.9% of patients, according to the International Knee Documentation Committee (IKDC), and in >80% of patients for all Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales, except for the KOOS Sport. mJSW increased from 2.7 ± 1.0 mm before surgery to 2.9 ± 1.0 mm at 2 years after surgery (p = .046). Complete meniscal healing was observed in 80.6%, with significant improvements in the International Cartilage Repair Society scores for medial femoral condyle and medial tibial plateau (p = .011, p = .006). MME was improved in 83.3% of patients.
Conclusion: Combined with pull-out repair, meniscal centralization and OWHTO significantly improved clinical, radiological, and arthroscopic outcomes at short-term follow-up, with a high proportion of patients achieving MCID thresholds in the Lysholm score, IKDC subjective score, and KOOS subscales.
期刊介绍:
Nowhere is minimally invasive surgery explained better than in Arthroscopy, the leading peer-reviewed journal in the field. Every issue enables you to put into perspective the usefulness of the various emerging arthroscopic techniques. The advantages and disadvantages of these methods -- along with their applications in various situations -- are discussed in relation to their efficiency, efficacy and cost benefit. As a special incentive, paid subscribers also receive access to the journal expanded website.
