研究目的:

髌骨不稳(PI)是儿童青少年常见的骨科疾病。目前治疗髌骨不稳的手术方案包括:采用股骨止点解剖位重建的内侧髌股韧带(MPFL)修复术,以及采用非解剖位股骨止点(收肌结节悬吊法)的MPFL重建术。但针对这两种术式优劣比较,目前尚缺乏严谨的随机对照试验研究。  

Objectives of Study:

Patellar instability(PI) is a common orthopedic condition in children and adolescents. Medial patellofemoral ligament (MPFL) femoral attachment anatomical reconstruction and MPFL reconstruction using adductor-sling at nonanatomic femoral attachment sites are both surgical options for treating patellar instability. However, there is a lack of rigorous randomized controlled trials comparing the advantages and disadvantages of these two surgical approaches.

随机方法(请说明由何人用什么方法产生随机序列):

手术技术分配方案将由研究负责人放入不透明密封信封中。信封密封后将进行随机打乱并连续编号,无需预先分层。当患者到达手术室麻醉间时,主刀外科医生将拆开随机信封,根据信封内的信息确定拟采用的手术技术,从而决定患者将接受何种手术方式。

Randomization Procedure (please state who generates the random number sequence and by what method):

The surgical technique assigned for use will be placed in opaque, sealed envelopes by the study investigator. After sealing, the envelopes will be randomly shuffled and then consecutively numbered. No pre-stratification is required. Once the patient arrives in the anesthesia room of the operating theater, the randomization envelope will be opened by the operating surgeon, who will determine the surgical technique to be used based on the information inside the envelope. This will decide which surgical technique the patient will receive.
