髌的

To investigate the outcome of medial patellofemoral ligament reconstruction using the semitendinosus tendon for recurrent dislocation of the patella.

目的探讨内侧髌股韧带重建术治疗复发性髌骨脱位及半脱位的手术方法及临床疗效。

Results: The extensor mechanism was wrapped up by trilaminar prepatellar fibrous soft tissues with different arrangement.

结果：髌前三层不同走向的纤维膜性结构包被伸膝装置。

Objective:To summarize clinical application of the medial sural artery pedicled muscle flap to cover soft tissue defects on the prepatellar region.

目的：总结腓肠内侧动脉带蒂肌瓣修复髌前软组织缺损的临床应用结果。

Lateral retinacular overlap suture and medial retinacular release could make patella tilt. Three months after operation, Outerbridge Ⅰ～Ⅱ grade cartilage degeneration could be seen in medial articular cartilage of patella.

采用外侧支持带紧缩缝合和内侧支持带松解可以造成山羊髌股关节倾斜，3月后发生以髌骨内侧面OuterbridgeⅠ级和Ⅱ级为主的病变。

KT-2000arthrometer side-to-side difference of anterior displacement was 13% versus 20% in Quadrupled-stranded semitendinosus group and patellar tendon group at 30 pounds.

但是，髌韧带组伸膝角度丧失(≤3°)的机率大于四股半腱肌腱组，分别为40％和6％，P＜0.001，有显著性差异。

Based on these MRIs, researchers determined how much cartilage loss occurred over time at the two joints of the knee: the tibiofemoral joint, where the thigh bone meets the lower leg bone; and the patellofemoral joint, behind the kneecap.

基于这些，磁共振成像，研究人员确定有多少软骨发生损失随着时间的推移，两个关节膝关节：胫股关节，大腿骨会见小腿骨骼；及髌股关节，后面膑。

Full-thickness cartilage defects, 0.5cm×0.5cm in size, were created at superior and lower area of femur trochlear in eight porcins (16 knees, 32 defects in all), the lesions in the right knees were untreated or treated by periosteum , the left knees were served as ACI groups (including monolayer and polylayer culture group), each defect was distributed into every control groups and every treated groups randomly.

在8头猪（16膝）股骨髁髌切迹上下各建立一个0.5cm×0.5cm大小的全层软骨缺损（共32个缺损），右膝为空白对照组和自体骨膜移植对照组，左膝为单层培养细胞组和复层培养细胞组，上下缺损随机进入各对照和试验组。

Objective To study the difference of healing process of reconstructing the knee cruciate ligaments with allograft tendons which were treated by program freezing and －80℃ deepfrozen.

目的 从实验角度观察程序冷冻液氮保存和－80℃深低温保存方法处理同种异体髌腱后重建膝关节交叉韧带的愈合过程并比较其差异。

Department of Orthopaedics,Qingdao Municipal Hospital,Qingdao 266000,ChinaAbstract:Objective To study the difference of healing process of reconstructing the knee cruciate ligaments with allograft tendons which were treated by program freezing and －80℃ deepfrozen.

目的 从实验角度观察程序冷冻液氮保存和－80℃深低温保存方法处理同种异体髌腱后重建膝关节交叉韧带的愈合过程并比较其差异。

Methods Reconstruct the ACL of the knee with the BPTB of rabbits which had been preserved for 2 weeks with －80℃ deepfrozen or liquid nitrogen deepfrozen after program freezing,and the cells poison response,cells activity,the maximum load and morphologic changes of the grafts were observed to compare the two allografting groups each other and compare them with the autografting group.

将兔的1/2骨髌腱骨复合体经-80℃深低温保存和程序冷冻液氮保存2周后观察冻存变化差异并行同种异体移植重建前交叉韧带，分别于术后3周和8周观察细胞毒反应、细胞活性、最大载荷和形态学变化等指标进行比较并与自体移植组对照。

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。
