移动式UKA是治疗前内侧KOA的有效方法。它具有创伤小、恢复快、保持正常的膝关节本体感觉的优点11,12,13。UKA的关键是屈伸平衡;即在恢复内侧副韧带张力的前提下，使屈曲间隙和伸展间隙尽可能相等14.这种不平衡可能导致轴承脱位、假体磨损或侧隔室15、16、17?...

膝关节骨关节炎（KOA）是一种全球负担1，目前采用逐步治疗策略。对于终末期单间室 KOA，单间室膝关节置换术 （UKA） 是一种有效的选择，10 年生存率超过 90%2。内侧 UKA 仅替换严重磨损的内侧间室，并保留自然外侧间室、内侧副韧带 （MCL） 和交叉韧带3.原理是通过胫骨截骨术和股骨磨削使屈曲间隙和伸展间隙大致相同，并在植入假体和轴承4后恢复内侧副韧带张力。与全膝关节置换术相比，UKA具有更大的手术难度和技术要求。主要来源是膝关节3整个运动范围内的韧带适当平衡。
传统上，在初步截骨术后，外科医生在关节间隙插入间隙测量仪，并通过感受内侧副韧带的张力间接确定屈伸间隙是否相等。然而，即使对于经验丰富的外科医生来说，平衡的定义和感觉也几乎不一样。对于初学者来说，掌握平衡的要求更加困难。屈伸间隙的不平衡会导致一系列并发症5,6，导致翻修率增加。
随着技术的进步，一些研究人员试图将张量应用于 UKA 7,8。然而，这些研究都是在固定轴承UKA上进行的，张量在使用时可能会损坏MCL。
传感器的出现不仅满足了显示膝关节间隙压力的需求，而且各种传感器由于其尺寸小，通常具有较小的MCL损伤风险9,10。此外，目前使用的传感器均为有线传输，可能会干扰无菌操作，使用起来不够方便。
为了准确测量屈伸间隙平衡参数，我们为UKA开发了一种无线传感器组合，该组合由金属底座，前侧，内侧和侧面带有三个压力探头的无线传感器以及缓冲块组成。传感器组合实时测量并显示关节空间的压力，以帮助外科医生准确评估是否达到了平衡目标。

in vitro application of a wireless sensor in flexion-extension gap balance of unicompartmental knee arthroplasty

单间室膝关节置换术（UKA）是终末期前内侧骨关节炎（AMOA）的有效治疗方法。UKA的关键是屈伸间隙平衡，这与术后并发症密切相关，例如轴承脱位，轴承磨损和关节炎进展。传统的间隙平衡评估是通过间隙计间接感知内侧副韧带的张力来进行的。它依赖于外科医生的感觉和经验，这对于初学者来说是不精确和困难的。为了准确评估UKA的屈伸间隙平衡，我们开发了一种无线传感器组合，由金属底座，压力传感器和缓冲块组成。截骨术后，插入无线传感器组合可以实时测量关节内压。准确量化屈伸间隙平衡参数，指导股骨进一步磨削和胫骨截骨术，提高间隙平衡的准确性。我们对无线传感器组合进行了 体外 实验。结果表明，应用由经验丰富的专家进行的传统屈伸间隙平衡方法后，差异为11.3 N。

这项 体外 研究是在一具60岁的女性尸体上进行的。外科医生使用S型股骨假体和3毫米的骨头支撑目标，在进行股骨磨削和胫骨截骨术后，使用间隙计初步评估屈伸间隙张力，并认为达到了平衡。
安装股骨试验后，将无线传感器插入内侧关节间隙，在屈曲110°（屈曲间隙）和20°（伸展间隙）处测量关节内压3次。屈伸间隙压力分别为49.9 N-44.8 N、47.1 N-25.9 N和42.0 N-34.2 N（<str...

我们的无线传感器实时量化屈伸间隙平衡的压力参数，这是单间室膝关节置换术的关键。传感器可以实时显示隔间压力，帮助外科医生更准确地评估屈伸平衡，并实现无线数据传输以满足术中无菌要求。UKA是膝关节骨关节炎的重要治疗方法，本协议中使用的传感器可以帮助UKA的动态术中评估，这对它的成功至关重要。该传感器专为移动轴承UKA设计，可以完美地适合UKA的假肢试验。此外，我们还为不同的假肢尺寸设计了匹配的传感器。该传感器专为UKA初学者设计，可缩短他们的学习曲线。该传感器非常易于操作，没有特定的技术。首先打开股骨和胫骨角测量装置。打开计算机上的角度测量软件。扫描两个测量设备的二维码，点击蓝牙连接。将两个角度测量仪器放在水平工作台上，然后单击校准按钮进行校准。用膝盖上的带子系住仪器，实时测量膝关节屈曲角度。将尸体置于仰卧位，下肢屈曲和外展覆盖在手术台外侧。使用内侧髌骨旁入路，用手术刀打开关节腔。现在，沿着髌骨内侧缘的顶点在关节线远端约三厘米处做一个切口，在胫骨结节内侧约一厘米处结束。使用龙格去除股骨内侧髁、髁间窝和胫骨前部的骨赘。将一毫米的股骨尺寸勺插入内侧隔室，以确定软骨关节空间的大小。插入不同大小的股骨尺寸勺来钩住股骨后髁。当勺子的末端距离软骨表面约一毫米时，选择与勺子相对应的股骨假体的大小。接下来，将一个三毫米的 G 夹连接到胫骨锯导轨和股骨尺寸勺。确保导板轴在冠状面和矢状面上平行于胫骨长轴，并且踝轭指向同侧髂前上棘。使用往复锯进行垂直胫骨锯切割。垂直向下推进锯，直到它停留在锯导轨的表面上。从胫骨切除导管上取下垫片并插入开槽的零垫片，然后使用摆动锯片切除平台。现在，取下开槽垫片，用宽截骨器将平台向上拉动，然后用膝盖伸展将其移除。在股骨远端髁上开一个洞。将髓内棒插入孔中。接下来，将股骨钻头导轨连接到髓内杆并进行股骨钻孔。将后切除导板安装到股骨的钻孔中。使用振荡锯进行股骨后髁截骨术，并取出导板和骨碎片。接下来，切除内侧半月板，留下半月板的小袖带以保护内侧副韧带。完全去除后角。插入零股骨插管并将球形磨机连接到股骨远端铣削，插入股骨试验并通过间隙规评估屈伸间隙。使用角度测量设备监测屈曲角度。将间隙规插入具有轻微阻力的关节空间，以定义屈伸间隙平衡。如果间隙不相等，则根据差异值研磨股骨，直到相等。卸下传感器磁感应电源开关。打开平板电脑上的压力测量软件。扫描传感器二维码，进入测量界面。单击连接设备按钮。根据量规规格选择合适的厚度缓冲块。将传感器放在金属底座上，然后将缓冲块安装在传感器上。单击在平板电脑上开始工作。将无线传感器组合插入内侧隔间，并将金属底座安装到胫骨截骨表面。测量膝关节屈曲 110 度和 20 度的屈曲和伸展间隙压力。分别计算三次连续测量的平均值。屈曲间隙的压力值非常一致，而拉伸间隙的压力值差异很大，弯曲时的平均压力为46.3 N，拉伸间隙的平均压力为35.0 N。术后X线片显示假体体位合适，胫股骨定位和屈曲角度良好。进行压力测量时，选择与假体尺寸相对应的传感器，以免损坏截骨表面并影响屈伸间隙平衡。间隙平衡后，平衡安装股骨和胫骨部件。将来，我们需要大样本多中心状态来确定传感器反映的屈伸间隙压差的可接受范围及其对UKA长期效果的改善。
