一個消費者教育項目介紹了一種微創(chuàng)完全膝關(guān)節(jié)置換術(shù)，幫助患者明白不同類型微創(chuàng)關(guān)節(jié)置換術(shù)之間的重要區(qū)別。

由Zimmer公司推出的這種新型微創(chuàng)手術(shù)，完全不損傷控制膝蓋彎曲運動的股四頭肌肌肉和肌腱。在傳統(tǒng)的膝關(guān)節(jié)置換術(shù)中需要切開、修補或者切除這些組織，導(dǎo)致患者在術(shù)后痊愈與康復(fù)時出現(xiàn)疼痛。這種被稱作MIS Quad-Sparing完全膝關(guān)節(jié)成型術(shù)（TKA），在手術(shù)的時候需要使用特殊儀器以及改良的外科技巧來進(jìn)行與傳統(tǒng)膝關(guān)節(jié)微創(chuàng)替代手術(shù)相同的、臨床證實有效的操作，但是手術(shù)切口更小。

與傳統(tǒng)完全膝關(guān)節(jié)置換術(shù)相比教，MIS Quad-Sparing TKA具有以下優(yōu)點：組織創(chuàng)傷少、手術(shù)切口較小而且不明顯、康復(fù)期縮短、術(shù)中失血少、疼痛少、住院時間短。迄今為止，已經(jīng)有2,000多例患者接受了Quad-Sparing膝關(guān)節(jié)置換術(shù)。

Zimmer公司主席、董事長、執(zhí)行總裁Ray Elliot說：“Quad-Sparing TKA手術(shù)方案花了兩年半時間才最終定型，讓醫(yī)生與患者明白這種手術(shù)與其它目前使用的微創(chuàng)手術(shù)之間的區(qū)別十分重要。”

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.
