Abstract：
(1) Background: Acute patella dislocation (APD) is a prevalent knee injury, with rates between 5.8-77.8 per 100,000. APD often results in repeat lateral patella dislocations due to the instability of the medial patellofemoral ligament (MPFL). Non-operative treatments have a 50% recurrence rate. While autologous grafting for MPFL has been favored, surgeons are now exploring synthetic grafts. We aimed to assess the effectiveness of synthetic grafts in MPFL reconstruction surgeries for repeated patellar dislocations; (2) Methods: Our research was based on a thorough search from the National Institute of Health and Clinical Excellence Healthcare Databases, using the Modified Coleman Methodology Score for quality assessment; (3) Results: Six studies met the inclusion criteria. A total of 284 patients and 230 knees were included. Seventy-five percent of patients were graded to have excellent-good clinical outcomes using the Crosby and Insall Grading System. International Knee Documentation Committee score and Knee injury and Osteoarthritis Outcome Score scores showed 59% and 60% post-operative improvement, respectively; (4) Conclusions: All studies showed improvement in post-operative functional outcomes and report no serious adverse events. The 6 mm, LARS (Orthomedic Ltd., Dollard-des-Ormeaux, QC, Canada) proved to have the most improvement in post-operative outcomes when used as a double bundle graft.
摘要：
(1)背景:急性髌骨脱位(APD)是一种普遍存在的膝关节损伤,费率在5.8-77.8/100,000之间。由于内侧髌股韧带（MPFL）的不稳定性，APD通常会导致重复的外侧髌骨脱位。非手术治疗有50%的复发率。虽然自体移植用于MPFL受到青睐，外科医生现在正在探索合成移植物。我们旨在评估MPFL重建手术中合成移植物对重复髌骨脱位的有效性；（2）方法：我们的研究基于美国国立卫生与临床卓越医疗数据库研究所的彻底搜索，使用改良的Coleman方法评分进行质量评估；（3）结果：6项研究符合纳入标准。共包括284名患者和230个膝盖。使用Crosby和Insall评分系统，有75％的患者被评分为具有良好的临床结果。国际膝关节文献委员会评分和膝关节损伤和骨关节炎结果评分显示59%和60%术后改善，结论：所有研究均显示术后功能结局改善，无严重不良事件。6毫米，LARS(OrthomedicLtd.,Dollard-des-Ormeaux,QC,加拿大）被证明在用作双束移植物时，术后结果的改善最大。
