| Popis: | Objectives The aim of our study was to compare the standard fabellotibial suture with Mini TightRope fixation for the treatment of a cranial cruciate ligament (CCL) rupture using a feline custom-made limb press. Methods Cadaveric hindlimbs of 10 cats were inserted in the limb press at predefined joint angles and loads of 10% and 30% body weight (BW) were applied. Mediolateral radiographs were taken and three-dimensional coordinates were recorded using a microscribe digitiser, with intact and transected CCLs and after either fabellotibial suture or Mini TightRope fixation were performed. Different distances and angles from radiographs or microscribe coordinates were analysed. Results Radiographic distances from the femoral condyle to the cranial edge of the tibia (X1–X2) were higher in CCL-deficient stifles than in intact stifles at 10% and 30% BW loads. All fabellotibial sutures and Mini TightRope fixations neutralised excessive cranial tibial thrust. A significant difference in the distance between the patella and tibial tuberosity (D2) was observed between CCL-deficient limbs and Mini TightRope-fixed limbs at 10% BW load ( P Conclusions and relevance Fixation of CCL-deficient stifles with lateral fabellotibial suture, as well as Mini TightRope tightened with a 20 N load, produces good biomechanical stability, as detected via radiographic assessment. |
