先前关于膝关节支架效果的运动学研究主要集中在前交叉韧带和支架对缺乏该韧带的膝关节的稳定作用1-23。这些研究大多集中在使用关节计的功能性膝关节支架的分析上2,3,5-8,10-15。其他研究集中在通过使用伦琴立体摄影分析技术分析股胫移位4,9,16,17，通过分类疼痛和功能能力对支撑进行主观评价18-22，以及确定不同类型的膝关节支撑的有效性，如铸造支撑23-26。虽然很少有研究评估卸载支架治疗单室关节炎退行性变的有效性，但先前的一项研究通过初步透视分析确定支架是在负重条件下治疗非肥胖患者膝关节骨关节炎的有效方法27。在对单一类型支架的调查中，结果没有评估三维运动，研究也没有确定不同类型的骨关节炎膝关节支架在相似条件下是否表现良好。
P revious kinematic studies on the effects of knee braces have concentrated primarily on the anterior cruciate ligament and the effects of bracing to stabilize the knee that has a deficiency of this ligament1-23. The majority of those studies have concentrated on the analysis of functional knee braces with use of arthrometers2,3,5-8,10-15. Other studies have concentrated on the analysis of femorotibial translation through the use of roentgen stereophotogrammetric analysis techniques4,9,16,17, subjective evaluation of bracing by categorizing pain and functional ability18-22, and the determination of the effectiveness of different types of knee braces, such as cast bracing23-26. Although minimal research evaluating the efficiency of off-loading braces for the treatment of unicompartmental arthritic degeneration has been performed, a previous study with an initial fluoroscopic analysis determined that bracing is an effective treatment for osteoarthritis of the knee in nonobese patients under weight-bearing conditions27. In that investigation of a single type of brace, the results were not assessed for three-dimensional motion and the study did not determine whether different types of osteoarthritic knee braces would perform well under similar conditions.
The objective of the present study was to analyze subjects with symptomatic unicompartmental osteoarthritis under in vivo, dynamic weight-bearing conditions with use of video fluoroscopy28,29 to determine whether five different off-loading knee braces provide separation of the medial femoral condyle from the tibial plateau, thus avoiding excessive loads on the degenerated compartment.
