Abstract

BACKGROUND AND AIM

Osteoarthritis is a common consequence of cranial cruciate ligament rupture (CCLR) in the canine stifle. Total knee replacement is a valuable method for managing end-stage osteoarthritis.

MATERIALS AND METHODS

Two new designs of total knee replacement implants were fabricated with information from computed tomography scans. Canine hind limbs of cadavers were tested with a biomechanical testing machine with C-arm fluoroscopy. The four groups tested were as follows: Intact stifles (INTACT), CCLR, total knee arthroplasty (TKA) with a peg on top of the tibial component (TKAP), and TKA with no peg on top of the tibial component (TKAN). Extension, flexion, adduction, abduction, internal rotation, external rotation, cranial translation, caudal translation, and range of motion were measured.

RESULTS

The cranial translation of the tibia relative to the femur increased significantly after cutting off the cranial cruciate ligament. After arthroplasty, adduction/abduction and cranial/caudal translation within the TKAN group was increased compared with the intact stifle group. In the TKAP group, only adduction was greater than it was in the intact stifle group.

CONCLUSION

The design of the prosthesis used for the TKAP group was more appropriate for total knee replacement in dogs than the design of the prosthesis for the TKAN group.

摘要

背景与目的

骨关节炎是犬科动物 stifle 中颅交叉韧带断裂（CCLR）的常见后果。全膝关节置换是治疗终末期骨关节炎的一种有价值的方法。

材料与方法

利用计算机断层扫描的信息制作了两种新型全膝关节置换植入物。使用带有 C 形臂荧光透视的生物力学测试机对尸体的犬后肢进行测试。测试的四组如下：完整 stifles（INTACT）、CCLR、胫骨部件顶部有栓子的全膝关节置换术（TKA）（TKAP）以及胫骨部件顶部无栓子的 TKA（TKAN）。测量了伸展、屈曲、内收、外展、内旋、外旋、向前平移、向后平移和活动范围。

结果

切断颅交叉韧带后，胫骨相对于股骨的向前平移显著增加。关节置换术后，TKAN 组内的内收/外展和前后平移与完整 stifle 组相比有所增加。在 TKAP 组中，只有内收大于完整 stifle 组。

结论

与 TKAN 组假体设计相比，TKAP 组使用的假体设计更适合犬的全膝关节置换。
