Knee pain secondary to problems with patellar tracking is common. The initial treatment for these problems is conservative. Patellar orthotics have been used extensively to treat a variety of extensor mechanism problems. Millions of health care dollars are spent annually on the use of these braces. There are many different patellar orthotics on the market today. The use and design of most of these devices are unclear and often lack a solid biomechanical foundation. The practical mechanical function of these braces is to reduce the lateral displacement of abnormal patellofemoral tracking. Orthotics that are designed and tested using practical biomechanical principles for applying a medially directed force to the patella seem to have a role in treating patients with knee pain secondary to patellar malalignment and instability. Well-defined and controlled clinical studies of the use of patellar braces are lacking.
继发于髌股关节轨迹问题的膝关节疼痛很常见。这些问题的初始治疗是保守治疗。髌股矫形器已被广泛用于治疗各种伸肌机制问题。每年在使用这些支具上花费数百万美元的医疗保健费用。如今市场上有许多不同的髌股矫形器。这些装置中的大多数的使用和设计尚不清楚，并且通常缺乏坚实的生物力学基础。这些支具的实际机械功能是减少异常髌股关节轨迹的侧向位移。使用实际生物力学原理设计和测试的、用于向髌骨施加向内定向力的矫形器似乎在治疗继发于髌骨排列不齐和不稳定的膝关节疼痛患者中发挥作用。目前缺乏关于使用髌股支具的明确且可控的临床研究。
