膝关节假体置换适应证选择是获得良好效果的关键

Proper selection of the prosthesis is the key to better clinical outcomes of total knee arthroplasty

随着社会明显老年化，膝关节骨关节炎及膝关节创伤性疾病越来越多，人工全膝关节置换术是治疗严重膝骨关节病及膝关节因创伤引起继发性骨关节炎临床有效的手术方法。选择适合患者的假体类型，关系到手术的成功与否。此外，临床上，还要考虑膝关节基本病变、畸形类型与膝部肌肉、韧带、软组织的质量以及患者的经济承受能力。这些因素使得临床医生的选择变得愈加困难。

In the last two decades, total knee arthroplasty was widely used in China. Among different designs, proper selection was the key to achieve satisfactory clinical outcomes. It was influenced by patho-physiological changes, types of abnormalities, quality of soft tissues, surgeons＇ clinical skills, as well as patients＇ insurance coverage. We analyzed different types of prostheses and concluded the advantages and disadvantages, especially clinical experience of indications and contraindications for the selection of proper prosthesis.
