Zimmer公司推出Quad-Sparing完全膝关节置换术

一个消费者教育项目介绍了一种微创完全膝关节置换术，帮助患者明白不同类型微创关节置换术之间的重要区别。

由Zimmer公司推出的这种新型微创手术，完全不损伤控制膝盖弯曲运动的股四头肌肌肉和肌腱。在传统的膝关节置换术中需要切开、修补或者切除这些组织，导致患者在术后痊愈与康复时出现疼痛。这种被称作MIS Quad-Sparing完全膝关节成型术（TKA），在手术的时候需要使用特殊仪器以及改良的外科技巧来进行与传统膝关节微创替代手术相同的、临床证实有效的操作，但是手术切口更小。

与传统完全膝关节置换术相比教，MIS Quad-Sparing TKA具有以下优点：组织创伤少、手术切口较小而且不明显、康复期缩短、术中失血少、疼痛少、住院时间短。迄今为止，已经有2,000多例患者接受了Quad-Sparing膝关节置换术。

Zimmer公司主席、董事长、执行总裁Ray Elliot说：“Quad-Sparing TKA手术方案花了两年半时间才最终定型，让医生与患者明白这种手术与其它目前使用的微创手术之间的区别十分重要。”

Quad-Sparing Total Knee Replacement
 
A minimally invasive total knee replacement procedure comes with a consumer education program to help patients understand important differences between various types of minimally invasive joint-replacement surgery.

This new minimally invasive surgery (MIS) from Zimmer Holdings, Inc. (Warsaw, IN, USA), entirely spares the quadriceps muscle and tendons, which control bending of the knee. The splitting, manipulating, or cutting of some of these tissues during traditional knee-replacement surgery causes much of patients’ pain during recovery and rehabilitation. Called MIS Quad-Sparing total knee arthroplasty (TKA), the procedure involves the use of special instrumentation and a modified surgical technique to place the same, clinically proven implants used in traditional knee MIS replacement surgery, but through a much smaller incision.

Compared to traditional total knee replacement surgery, the advantages of the MIS Quad- Sparing TKA include less tissue trauma, a smaller, less conspicuous incision, shorter total rehabilitation, less blood loss, less pain, and a shorter hospital stay. To date, more than 2,000 patients have had knees replaced with the Quad-Sparing technique.

“Quad-Sparing TKA has been two-and-a-half years in the making, and it’s important for physicians and patients to understand the distinction between the benefits of this technique and other minimally invasive techniques available today,” noted Ray Elliot, chairman, president, and CEO of Zimmer.
