Abstract

Purpose

To date, there have been limited studies reporting the mid- to long-term outcomes of meniscoplasties for discoid lateral meniscus. The current study aims to evaluate the mid- to long-term outcomes of arthroscopic meniscoplasty for discoid lateral meniscus in children and adolescents.

Methods

In the study, all patients under the age of 21 years who had undergone arthroscopic meniscoplasty with or without meniscal repair or partial meniscectomy for symptomatic lateral discoid meniscus were included. All patients were then followed up for a minimum of 5 years (median 84 months; range 68–110 months). The Lysholm scores and Ikeuchi scores were collected pre-operatively and at final follow-up and were compared.

Results

A total of 24 knees were included in the study. The median duration of follow-up was 84.0 months (range 68–110 months). The Lysholm score improved from 53 (range 11–95) pre-operatively to 100.0 (range 60–100) at final follow-up (p < 0.001). Based on the Ikeuchi score pre-operatively, 15 knees were rated as poor (62.5%), 7 knees were rated as fair (29.2%), and 2 knees were rated as good (8.4%). The Ikeuchi score improved significantly at the final follow-up, such that 1 knee was rated as good (4.2%) and 23 knees were rated as excellent (95.8%) (p < 0.001). When analysing the effect of concomitant meniscal repair or partial meniscectomy on the outcomes at final follow-up, there was no apparent difference in the improvement in Lysholm score or Ikeuchi score when comparing between patients who had meniscoplasty alone and patients who had concomitant meniscal repair, as well as when comparing between patients who had meniscoplasty alone and patients who had concomitant partial meniscectomy.

Conclusion

Meniscoplasty leads to good mid-term to long-term outcomes for children and adolescents with discoid lateral meniscus. Concomitant procedures such as meniscal repair or partial meniscectomy do not improve or worsen the mid- to long-term outcomes in these patients.

椎间盘成形术可为患有盘状外侧半月板的儿童和青少年带来良好的中期至长期效果

摘要

目的

迄今为止，很少有研究报道盘状外侧半月板的整形术的中长期结果。当前的研究旨在评估儿童和青少年椎间盘状半月板关节镜黏膜成形术的中长期效果。

方法

在这项研究中，纳入了所有21岁以下接受过有症状的侧盘状半月板修复或不进行半月板修复或部分半月板切除的关节镜下整形术的患者。然后所有患者随访至少5年（平均84个月;范围68 - 110个月）。术前和最终随访时收集Lysholm评分和Ikeuchi评分，并进行比较。

结果

该研究总共包括24个膝盖。中位随访时间为84.0个月（范围68 – 110个月）。术前Lysholm评分从术前的53（11 – 95）提高到100.0（60 – 100）（p  <0.001）。术前根据Ikeuchi评分，不良15膝（62.5％），正常7膝（29.2％），良2膝（8.4％）。在最后的随访中，Ikeuchi评分显着提高，因此，1膝被评为良好（4.2％），23膝被评为优秀（95.8％）（p <0.001）。当分析半月板修复或部分半月板切除术对最终随访结局的影响时，将单独进行增粘成形术的患者与半月板修复同时进行的患者进行比较，Lysholm评分或Ikeuchi评分的改善无明显差异，以及比较单独进行了整形术的患者和同时进行部分半月板切除术的患者之间的比较。

结论

对于患有盘状外侧半月板的儿童和青少年，粘膜成形术可带来良好的中期至长期效果。半月板修复或半月板切除术等伴随手术并未改善或恶化这些患者的中长期疗效。
