To evaluate the approaches and procedures used by knee surgeons in Brazil for treating medial patellofemoral lesions (MPFL) of the knee in cases of acute traumatic dislocation of the patella.
A questionnaire comprising 15 closed questions on topics relating to treating MPFL of the knee following acute dislocation of the patella was used. It was applied to Brazilian knee surgeons during the three days of the 44th Brazilian Congress of Orthopedics and Traumatology, in 2012.
106 knee surgeons completely filled out the questionnaire and formed part of the sample analyzed. Most of them were from the southeastern region of Brazil. The majority (57%) reported that they perform fewer than five MPFL reconstruction procedures per year. Indication of non-surgical treatment after a first episode of acute dislocation of the patella was preferred and done by 93.4% of the sample. Only 9.1% of the participants reported that they had never observed postoperative complications. Intraoperative radioscopy was used routinely by 48%. The professionals who did not use this tool to determine the point of ligament fixation in the femur did not have a statistically greater number of postoperative complications than those who used it (p > 0.05).
There are clear evolutionary trends in treatments and rehabilitation for acute dislocation of the patella due to MPFL, in Brazil. However, further prospective controlled studies are needed in order to evaluate the clinical and scientific benefit of these trends.
评估巴西膝关节外科医生在髌骨急性创伤性脱位病例中治疗膝关节内侧髌股韧带损伤（MPFL）所采用的方法和步骤。
采用一份包含15个封闭式问题的问卷，这些问题涉及髌骨急性脱位后膝关节MPFL损伤的治疗。该问卷于2012年巴西第44届骨科学与创伤学大会的三天会议期间发放给巴西的膝关节外科医生。
106名膝关节外科医生完整填写了问卷并成为分析样本的一部分。他们大多数来自巴西东南部地区。大多数人（57%）报告称，他们每年进行的MPFL重建手术少于5例。93.4%的样本更倾向于并采用了髌骨首次急性脱位后的非手术治疗指征。只有9.1%的参与者报告称他们从未观察到术后并发症。48%的人常规使用术中透视。未使用该工具来确定股骨韧带固定点的专业人员术后并发症的数量在统计学上并不比使用该工具的人员多（p>0.05）。
在巴西，由于MPFL导致的髌骨急性脱位的治疗和康复存在明显的演变趋势。然而，需要进一步进行前瞻性对照研究，以评估这些趋势的临床和科学益处。
