Conclusion]1? It showes a higher stress dodge in the calcar femorale after using various kinds of prosthesis implantation? After using CFR/PSF of lower elastic modulus as handle, the stress dodge rate is lower in femur, but the interface stress is higher, and this is the main factor and reason for the prosthesis loosening? 2? The stress force rule meets the design principle that the stress force decreases gradually in the bone interface from proximal to distal? The stress value in different combination of same prosthesis handle has no significant difference, that showes mechanical factor is not the main standard for selecting prosthesis combination?
[结论] 1、各种假体植入后均在股骨距处形成较高的应力遮挡,而用弹性模量较低的CFR/PSF作为柄,其股骨相应区域的应力遮挡率较低,但股骨相应界面应力较大,而界面应力过大是产生假体微动主要因素。2、股骨界面从近端至远端呈逐渐增高趋势的应力规律符合该假体的设计原理;相同假体柄的不同组合其股骨和髋臼相应界面应力值无明显差别,实验表明力学因素并不是选择假体组合的主要标准。

Results: The BMD decreased fastest in the first year after operation, as the postoperative time prolonged, the BMD decreased markedly at the medial part of the stem especially at the calcar and under calcar part, and at the medial part of the stem and the large trochanter, the BMD at the lateral lower part of the stem decreased at a lower extent, the femur shaft part under the tip of the stem lost the lest bone.
结果:术后第一年骨丢失多,随术后时间延长,假体柄内侧尤其是股骨矩及矩下R7、R6区、假体尖内侧R5和大粗隆区R1区骨丢失最明显,假体柄外侧中、下R2、3区端次之,假体柄尖远端股骨干处R4区骨丢失相对较少。

The mean range of motion was improved from preoperative 84°(40°-95°) to postoperative 104°(80°-120°); the mean preoperative Knee Society Scores were increased from preoperative 39 scores (10-67 scores) to 87(10-100), and the function was improved from 38 scores (0-60 scores) to postoperative 76(20-100). Alignment was obtained in 31 knees, with well localized femoral and tibial prostheses. The tibial prosthesis of 1 case developed inadequate retroversion; of 2 cases remained 2°-3° inversion; non-progressive radiolucent zone was found between tibial prosthesis and bone interface of 1 case.
膝关节活动度从置换前平均84°(40°~95°)增加到置换后平均104°(80°~120°),膝关节评分从置换前平均39分(10~67分),提高到随访时平均87分(10~100分),功能评分从置换前平均38分(0~60分)提高到随访时平均76分(20~100分)。31膝获得肢体的良好对线,股骨及胫骨假体位置良好。1例胫骨假体后倾不足,2例胫骨假体残留2°~3°内翻,1例胫骨假体与骨组织界面存在非进展性透亮带。

The most common causes of failed surgery found in 24 cases were aseptic loosening and peri-prosthetic osteolysis, wear-out of acetabulum was seen in 7, malpositioned prostheses in 6 and postoperative dislocation in 3. Infection and fracture of femoral stem happened in 3 and 2 patients respectively.
最常见的原因是假体松动、假体周围骨溶解,共24例次,其次为人工股骨头引起髋臼磨损7例次,假体置入位置不良6例次,人工髋关节脱位3例次,术后感染3例次,假体股骨柄断裂2例次。
