髌的

Objective To discuss a new method of curing the damnification at infrapatellar structure (patellar ligament and the structure around it).

目的 探讨髌下结构损伤的新的治疗方法。

Objective: To compare the different parameters of the patellofemoral joint in kinematic MR in normal and abnormal groups under various degree of flection.

目的：通过测量髌股关节动态MRI的一些参数，比较不同屈曲角度下正常人及患者之间的差异性。

Autogenous semitendinosus tendon and gracilis tendon or autogenous bone - patellar tendon (middle 1/3)- bone are mainly used for anterior cruciate ligament reconstruction at home and abroad.

应用自体半腱肌腱和股薄肌腱或者应用自体骨-髌腱(中1/3)-骨重建前交叉韧带的方法是国内外重建前交叉韧带的主要方法。

Usually the anterolateral approach is not as satisfactory as the anteromedial one, primarily because it is more difficult to displace the patella medially than laterally.

通常，膝关节的前外侧入路不如前内侧人路效果满意，主要是由于髌骨更难向内侧脱位、另外，此法需要更长的皮肤切口，而且髌韧带经常要做骨膜下或皮质下部分游离。

5 Patellar fractures are the second commonest periprosthetic fracture of the knee, with a reported incidence of patello-femoral complications (fracture, loosening, radiolucency) from

髌骨骨折是第二常见的膝部假体周围骨折，报道髌股并发症的发生率自0.15%－12%。

The healing process and histological behavior of the tendon transplantation group were similar with those of the autografting group, however, which was better by liquid nitrogen after program freezing than by -80℃ deepfreezing.

结论经程序冷冻液氮保存和-80℃深低温保存方法冻存的兔异体髌腱重建膝关节交叉韧带后愈合过程和自体韧带移植重建过程相似，但程序冷冻液氮保存法优于传统的-80℃深低温保存法。

Objective:To study the location and the length of cruciate ligament transposed from patellar ligament and the clinical significance.

目的：探讨髌韧带移植重建交叉韧带距离及重建点的位置对膝关节功能恢复的影响。

We chose 15 fresh adult knee samples without obvious genual diseases ( 5 examples of extended position,5 examples of flexed 45 degrees position, 5 examples of flexed 90 degrees position ), embed the samples of different functional positions with 5% blue glutin, and obtained 0.5mm sample by mill cuts technology at low temperature condition.

对无明显膝关节病变的成年志愿者60人，在MRI上选用SE-T1加权，做层厚2.0mm无间距扫描，TR1500ms，TE15ms。测量膝关节由全伸位到屈曲位前、后交叉韧带的长度和厚度，并观察髌股位置关系。

It is more congruent with biologic mechanies and normal physiological anatomise,and it is more sensitively and effectively to detect early or dormant patello-femoral disease. Keywords:weight-bearing, Merchant view, Patello-femoral, projecting technology.

负重髌骨轴位投照法操作简便，实用性强，更符合生物力学原理，切合正常生理解剖，临床应用对早期及隐匿性髌股关节紊乱的检测更灵敏、更有效。

The decreased extent of amplitude of femoral nerve maximal electrical twitch and quantitative patella tendon reflex were compared.

同时作股神经最大电刺激和定量髌腱反射时，肌电波幅减低程度之间的比较。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
