Reconstruction of the medial patellofemoral ligament (MPFL) with nonresorbable suture tape (FiberTape) could be an alternative to MPFL reconstruction (MPFLR) using an autologous tendon graft after a first-time patellar dislocation.
To investigate whether good clinical and radiological results are achievable with this technique.
Case series; Level of evidence, 4.
Between January 2017 and September 2020, a total of 30 patients with acute first-time patellar dislocation and a low anatomic risk factor constellation of patellar instability underwent MPFLR using nonresorbable suture tape combined with cartilage surgery if necessary. After a minimum 2-year follow-up, the Banff Patella Instability Instrument 2.0 (BPII 2.0)-a numerical analog scale (NAS, 0-10) for patellofemoral pain (PFP) (NAS pain) and subjective knee joint function (NAS function)-was used to assess patients' reported quality of life after surgery in 20 patients (men/women: 14/6; age, 22.2 ± 6.1 years; 67% follow-up rate). Magnetic resonance imaging (MRI) scans of the surgically treated knee joint were conducted, and the Area Measurement And DEpth & Underlying Structures (AMADEUS) scores were evaluated pre- and postoperatively.
The BPII 2.0 score was 81 ± 12.5 (55.2-94.7) points postoperatively. The subjective rating of knee joint function (NAS function) was 8.5 ± 1.5 (4-10), and the PFP (NAS pain) was 1.5 ± 1.7 (0-5) postoperatively. MRI evaluations showed an increase in the AMADEUS score in all patients from 79 ± 24.3 points (40-100 points) preoperatively to 92.3 ± 9 points (75-100 points) postoperatively ( = .02).
MPFLR with nonresorbable suture material can achieve satisfactory clinical and radiological outcomes after an acute first-time patellar dislocation.
对于首次髌骨脱位后内侧髌股韧带（MPFL）重建，使用不可吸收缝线带（FiberTape）可能是自体肌腱移植进行MPFL重建（MPFLR）的一种替代方法。
研究该技术是否能取得良好的临床和影像学结果。
病例系列；证据水平，4级。
2017年1月至2020年9月期间，共有30例急性首次髌骨脱位且髌骨不稳定解剖危险因素较低的患者接受了MPFLR，必要时联合软骨手术，使用不可吸收缝线带。经过至少2年的随访，采用班夫髌骨不稳定器械2.0（BPII 2.0）——一种用于评估髌股疼痛（PFP）（NAS疼痛）和主观膝关节功能（NAS功能）的数字模拟量表（NAS，0 - 10）——对20例患者（男/女：14/6；年龄，22.2±6.1岁；随访率67%）术后的生活质量报告进行评估。对接受手术治疗的膝关节进行磁共振成像（MRI）扫描，并在术前和术后评估面积测量与深度及基础结构（AMADEUS）评分。
术后BPII 2.0评分为81±12.5（55.2 - 94.7）分。术后膝关节功能主观评分（NAS功能）为8.5±1.5（4 - 10），PFP（NAS疼痛）为1.5±1.7（0 - 5）。MRI评估显示，所有患者的AMADEUS评分从术前的79±24.3分（40 - 100分）增加到术后的92.3±9分（75 - 100分）（P = 0.02）。
对于急性首次髌骨脱位，使用不可吸收缝合材料进行MPFLR可取得满意的临床和影像学结果。
