The primary objective was to compare the functional outcomes after an isolated MPFL reconstruction using either a quasi-anatomical technique (group A) or an anatomical MPFL reconstruction (group B). The secondary objectives were to compare the rates of redislocation, range-of-motion and subjective patellar instability (Smillie test).
A multicenter longitudinal prospective comparative study was performed. Group A had 29 patients and 28 were included in Group B. Patients with trochlear dysplasia types C and D and patients who had undergone a trochleoplasty, a distal realignment or patella distalization concurrently with MPFL reconstruction were excluded. The main evaluation criterion was the Kujala functional score.
The mean postoperative Kujala was 90.4 (89.4 in group A and 92.1 in group B). Upon comparing the mean difference between pre- and post-operative values, no differences were detected between the two groups (n.s).
Isolated quasi-anatomical MPFL reconstruction using a gracilis tendon autograft for recurrent patellar dislocation provides outcomes as good as the isolated anatomical MPFL reconstruction in patients with no trochlear dysplasia up to those with trochlear dysplasia type A and B at the 2-5 years follow-up.
Level IV.
本研究的主要目的是比较使用解剖型（A 组）和非解剖型（B 组）单束前交叉韧带重建术后的功能结果。次要目的是比较复发性髌骨脱位患者接受单束前交叉韧带重建术后的再脱位率、活动范围和主观髌骨不稳定（Smillie 试验）。
进行了一项多中心前瞻性对照研究。A 组有 29 例患者，其中 28 例纳入 B 组。排除滑车发育不良 C 型和 D 型患者，以及同时行滑车成形术、远端矫正术或髌骨下移术的患者。主要评估标准为 Kujala 功能评分。
术后平均 Kujala 评分为 90.4 分（A 组为 89.4 分，B 组为 92.1 分）。比较术前和术后的平均差值，两组间无差异（n.s）。
在 2 至 5 年随访中，对于无滑车发育不良、A 型和 B 型滑车发育不良患者，使用自体股薄肌腱进行非解剖型单束前交叉韧带重建术治疗复发性髌骨脱位的效果与解剖型单束前交叉韧带重建术相当。
IV 级。
